In patients with pre-existing spondylosis or spinal canal stenosis gastritis diet australia generic lansoprazole 30 mg with amex, hyperextension injuries are more likely to injure the spinal cord gastritis dieta recomendada lansoprazole 30 mg buy on-line, particularly in the cervical spine with a poorer prognosis gastritis diet àëèýêñïðåññ lansoprazole 30 mg. At any level gastritis diet 8 jam 15 mg lansoprazole sale, the cord is vulnerable to transection if the applied forces are sufficient; however digestive gastritis through diet generic lansoprazole 15 mg buy, cord transection cannot be presumptively diagnosed based on fracture dislocation pattern. Axial gradient echo T2* is also employed, particularly in the cervical and thoracic segments. Acute intramedullary hemorrhage is seen as a focus of T2 shortening (hypointensity) [15]. Four prognostication patterns are predictive of neurological outcome (normal, single-level edema, multi-level edema, and mixed hemorrhage and edema) [27]. Cord contusion carries a worse prognosis since it may evolve into cyst formation, but recovery may occur in 70% of patients with incomplete spinal cord syndromes. The presence and extent of spinal cord hematoma are each significantly associated with poor long-term neurological outcomes. Cervical cord intramedullary hematomas have a strong correlation with a complete neurologic deficit and irreversible spinal cord injury. Special Circumstances/Conditions Pediatric Pediatric spine injuries are not in the purview of this chapter. In general, spine injuries in children are much less common than in adults, the criteria for imaging and screening are different and less well defined (in part related to less evidence), and a guiding principle should be very judicious use of ionizing radiation imaging modalities because of potential downstream consequences of neoplasm. Geriatric the incidence and type of cervical spinal injury in the elderly patient (older than 65 years) differs from those in younger patients because spondylosis (degenerative changes) and/or decreased bone mineralization (osteoporosis) predisposes to vulnerability of low-velocity injuries (such as a fall from standing height) [29]. Typically, upper cervical spine injuries, especially at C2, are caused by hyperextension in patients with degenerative changes [30]. Pseudofractures There are many normal anatomical variants that can simulate disease, including some that can be confounded for spinal trauma [31]. The craniocervical junction and upper cervical spine have a number of these, owing to the unique transitional aspects of this anatomy. In some people, nonfusion of the atlas (C1) ossification centers results in a cleft that persists into adulthood showing smooth corticated margins, which helps distinguish it from a fracture. Clefts of the atlas most commonly occur at the posterior synchondrosis, but may occur anywhere within the C1 ring, including rarely anteriorly (0. In response there may be overgrowth of the neural arches at the margins of the cleft as they attempt to fuse. The atlantooccipital membrane may become partially or completely ossified (latter resulting in an arcuate foramen). The odontoid process of C2 may have a persistent os terminale (small summit ossification center) or os odontoideum (larger fragment which may involve the base and extend into the body of C2). When an os odontoideum is developmental it may have a dysplastic appearance and be associated with a hypertrophic anterior arch of C1. A remnant of subdental synchondrosis of C2 often persists into adulthood, appearing as a sclerotic line surrounded by lucency at the base of the dens. Clefts may have multiple locations in verterbrae involving the subaxial portions of the spine. Spina bifida occulta results from failed osseous fusion of the posterior synchondrosis. A cleft may also occur within the pars interarticularis (spondylolysis), pedicle (retrosomatic cleft) or lamina (retroisthmic cleft). An isolated defect within the bony wall of the transverse foramen is a very uncommon variant that is unlikely to represent a fracture (the latter of which is characterized by disruptions in two locations with displacement of the fragment). Anterior wedging of the vertebral bodies can also be a normal finding in adults at the thoracolumar junction. Occasionally, a Schmorl node might be initially confused with an acute fracture, particularly if there is associated physiologic wedging of the vertebral body. Occasionally, secondary ossification centers may remain unfused later into adulthood (beyond 16-25 years). The margins will be smooth and corticated as opposed to acute fractures, which are irregular and noncorticated. They are more common in the thoracic and cervical spine than in the lumbar region. Conclusion the main objectives of imaging patients with spinal trauma are: rapid and accurate depiction of the spinal axis, identification of (potentially) unstable injuries, and assisting decision making for surgical treatment. Radiologists who interpret trauma images should have basic concepts of spinal instability because the lack of detection and characterization of these injuries places the patient at risk of pain and neurological dysfunction. While the exact classification or specific nomenclature can be important to facilitate uniform communication, the critical element is identifying this as an unstable lesion. Cervical spine trauma in children is rare and the diagnosis can be challenging due to anatomical and biomechanical differences as compared with adults. Recognition of the normal developing spine and variants can prevent misdiagnoses of injury. Denis F (1984) Spinal instability as defined by the three-column spine concept in acute spinal trauma.

Although overlap exists, inflammatory disorders can predominantly affect the synovial articulations of the spine (rheumatoid disease) or primarily the enthesis of ligaments and intervertebral discs (seronegative spondyloarthropathies). The various disease states are not static but rather need to be viewed as dynamic and progressive, usually resulting in complications. In rheumatoid disease it is primarily the cervical spine that is involved, but it is very rare that the rheumatoid arthritis patient presents with cervical spine manifestations as the first mode of presentation. On the other hand seronegative spondyloarthropathies usually present with axial manifestations of enthesitis as the first mode of presentation, and these are easily overlooked. Synovial involvement of the cervical spine in seropositive inflammatory states has a predilection for the facet joints, and in particular the C1-C2 articulations. In seronegative spondyloarthropathy, the inflammatory site is the enthesis where the collagen of the ligaments or intervertebral disc annulus enters bone directly. The cause of the inflammatory process is the generation of cytokines, which results in edema, bone erosion, disorganization of bone and ligament structure, which promotes a reactive osteitis and eventually ossification of the ligaments commencing at the enthesis interface. The seronegative spondyloarthropathies can be further categorized based on the imaging findings equated to the clinical features and laboratory findings. Inflammatory back pain that is worse at night and in the early morning is the key clinical hallmark of inflammatory spondyloarthropathy. Ankylosing spondylitis usually presents with early morning stiffness that is eased by movement and exercise. However the onset is usually insidious allied with multiple relapsing episodes of back pain that usually starts in the lumbar spine. The condition can remain undiagnosed for years, resulting in fusion of the spine, which renders the condition painless. Although classification subtypes have evolved over the last 30-40 years, the main challenge facing the radiologist is the early diagnosis of inflammatory spinal disorders because the early institution of therapy can limit disability and diminish disease progression. It is a fundamental component required in establishing 128 Inflammatory Disorders of the Spine 129 the diagnosis of ankylosing spondylitis, but it is also relevant to the other spondyloarthropathies. In ankylosing spondylitis it is bilateral and symmetrical, while in psoriatic spondyloarthropathy and reactive arthritis it can be bilateral or unilateral. Involvement of the axial skeleton is unusual and indeed rare in the absence of sacroiliitis. Conventional radiography remains the initial diagnostic imaging modality recommended despite its low sensitivity and relatively high false-negative rate in early disease. There are inherent limitations to the proper radiographic assessment of the sacroiliac joints; these arise because the joints themselves are divergent in the anteroposterior projection, which is why a posteroanterior projection is usually a better option of assessing the sacroiliac joints. It is also well known that conventional radiography can miss advanced sacroiliitis. Early inflammatory sacroiliitis can result in a loss of the sharpness of the subchondral bone outline of the joint; this then progresses to becoming irregular due to the presence of erosions, and this in turn produces an appearance of localized joint widening. Sclerosis of the subchondral bone on either side of the joint is fairly diagnostic in established disease, especially when it involves the inferior and middle portion of the joint and is more pronounced on the iliac side. However, in established disease, the sacroiliac joint can also exhibit loss of sharpness due to ossification across the joint leading to ankylosis. The modified New York criteria have identified five radiographic stages of sacroiliac joint involvement: Grade 0: no abnormality Grade 1: suspicious changes Grade 2: sclerosis with early erosions Grade 3: severe erosions, pseudo joint widening and partial ankylosis Grade 4: complete ankylosis. In practice, however, radiological detection of these changes is challenging with poor interobserver and intraobserver reliability for the changes in early disease, namely stages 1 and 2. The relatively late development of radiographic changes in ankylosing spondylitis is undeniably one of the factors that can delay the diagnosis. T1-weighted spin-echo sequences are, however, better at depicting articular erosions. The degree of the edema can vary, ranging from florid, fairly extensive areas of periarticular edema to more focal and localized zones of edema paralleling the joint line. It is usually the inferior iliac portion of the joint that is involved in the early stages of sacroiliac inflammatory change. They are particularly helpful in determining whether the instituted drug regime is working, identifying a need to alter the drug regime, and deciding to stop drug regimes if they are not working in view of the significant side-effects and high cost. However, one needs to bear in mind that sclerosis on its own can have a similar appearance in both active disease and in burnt-out inflammation. Axial Skeleton Ankylosing spondylitis is the seronegative spondyloarthropathy prototype. It is primarily a disease of the axial skeleton involving the sacroiliac joints and the spine. The primary target organ is the enthesis where the spinal longitudinal ligaments and annulus fibrosus merge directly with the bone. In the early manifestations of inflammation an osteitis is produced by the inflammatory response, and this leads to bone marrow edema and then subsequently this is followed by reactive sclerosis and eventually ossification of the involved ligaments. There is usually an orderly progression of involvement of the spine commencing first in the thoracolumbar and lumbosacral regions, and then advancing to the midlumbar, midthoracic and eventually the cervical spine. Spondylitis Spondylitis occurs in about 50% of ankylosing spondylitis patients, although females are relatively less affected. The earliest changes are caused by enthesitis at the insertion of the outer fibers of the annulus fibrosus on the ring apophysis of the vertebral end plate. Although this occurs circumferentially, it is predominantly the anterior attachment that usually produces the more florid manifestations. Subtle erosions with reactive sclerosis in the vertebral corners are seen, and radiographically these 130 V. Cassar-Pullicino have been referred to as Romanus lesions when viewed as erosions, and "shiny corners" when the erosion is associated with sclerosis due to the reactive osteitis. The Romanus erosive disease can also produce an apparent squaring of the anterior outline of the vertebral body. However, the Romanus lesions are short lived and resolve by producing resultant syndesmophyte formation. The syndesmophytes represent the ossification of the outer fibers of the annulus fibrosus in ankylosing spondylitis. They are seen radiographically as very fine and symmetric in appearance, bridging the intervertebral space. This may initially appear at a single disc level, but usually progresses to involve multiple segments producing the socalled characteristic "bamboo spine". The same inflammatory process results in ossification of the longitudinal ligaments, which insert onto the vertebral bodies producing squaring of the vertebral body appearance as the fusion progresses. Multiple contiguous areas of high T1 signal can be seen in vertebral bodies and in particular at their corners in segments of the spine that have undergone extensive fusion. This has been related to the presence of calcification or alternatively the presence of marrow within mature transdiscal ankylosis. They can be useful in the acute phase of inflammatory change, particularly in the early manifestations of the disease. In acute Romanus lesions, contrast medium injection usually renders the erosions more clearly defined. Spondylodiscitis There are two types of spondylodiscitis that can be detected within the discovertebral junction. The primary spondylodiscitis is usually a sign of early discovertebral involvement with a stable spinal status. In the secondary spondylodiscitis, or as it sometimes known Andersson type B lesions, there is more extensive and florid discovertebral disease and destruction. The degree of vertebral destruction is usually mild, but there is often extensive bony edema and bony sclerosis, and in long established cases the endplates can be completely destroyed on both sides of the intervertebral disc. In Andersson type B lesions the spine is unstable at the site of involvement because of increased mobility. This increased mobility could be at a level between fused segments or be associated with deficiency of the posterior elements where there is a pseudoarthrosis due to a fracture.

Which of the following is the most appropriate course of action for the physician to take regarding his colleague While at work, the colleague appears disen gaged, distracted, moody, and forgetful. He asked his colleague if something is wrong and was rebuffed, being told that he is fine. The patient is an ortho pedic surgeon and has experienced loss of consciousness on three separate occasions over the past 6 months after prolonged standing in the operating room. Each episode was brief, was preceded by darkening of peripheral vision, and occurred approximately 2 hours into each surgical procedure. She reports no chest pain, palpitations, weak ness, headache, sensory symptoms, flushing, or nausea before the episodes, and no bladder or bowel incontinence or postevent confusion were seen following syncope. She had a normal evaluation in the emergency department after each episode with a normal physical examination, laboratory studies, and electrocardiogram.

D: 23714311] Bibliography · Assessing the pretest probability of heparin-induced thrombocytopenia by using a risk scoring system, such as the 4T score, is helpful in guiding therapy in patients at low risk for it. A multicenter, randomized, con trolled clinical trial of transfusion requirements in critical care. This patient has modest coagulopathy and throm bocytopenia resulting from hepatitis C-related liver dis ease. Previous retrospective studies have shown that central venous catheter insertion is safe in patients with a prolonged prothrombin time and! Cryprecipitate in the prophylaxis of bleeding tor patients with low fibrinogen levels undergoing procedures has not been evaluated. Most procedures and surgeries can be safely performed with a platelet count of at least 50. Therapy may be required for patients with platelet counts lower than 30,000 to 40,000/µL (30-40 x 109 /L) or with bleeding. She has pseudothrombocytopenia as shown on the periph eral blood smear, a condition that leads to the formation of platelet clumps in vitro. The auto mated platelet counter does not recognize the clumps as masses of platelets, and the platelet count is, therefore, spu riously low. Drawing a complete blood sample into a citrate or heparin-anticoagulated tube may resolve the clumping. How ever, unless a trial of desmopressin shows a robust, sustained response, it should not be used for a major surgery. Other risks include viral transmission, transfu sion-related acute lung injury, and febrile, allergic, and ana phylactic reactions. Pro longed use of these agents is associated with the potential for thrombosis, especially in patients with an underlying thrombophilia. Used as a single agent, tranexamic acid is unlikely to provide sufficient hemostasis for a patient undergoing abdominal surgery. Cold agglutinin disease may occur as a primary disorder or may be associated with a lymphoproliferative disorder or certain infections, such as Mycoplasma pneumoniae or Epstein-Barr virus. However, testing for this disorder is indicated only in patients without evidence of an autoimmune cause of hemolysis. Therefore, hemoglobin electrophoresis would not likely be helpful in establishing the cause of his hemolysis. The indirect antiglobulin test detects antierythrocyte antibodies in the serum and is used primarily before blood transfusion and in prenatal testing of pregnant women. Autoimmune hemolytic anemias are characterized by the presence of antibodies directed toward antigens on the surface of erythrocytes; they are further classified by the type of irnmunoglobulin involved and the resulting tendency of hemolysis to occur in warm or cold environments. The immune response to the bound lgG causes erythrocytes to become spherocytic, resulting in hemolysis. The lgM antibodies fix complement and then detach from erythrocytes when they return to the warmer body core. He has inflammatory anemia (previously ane mia of chronic disease), which does not usually require treatment. Chronic infections such as tuberculosis or osteo myelitis, malignancies, and collagen vascular diseases are associated with anemia. In response to inflammatory states, erythropoietin production is inhibited and the erythroid precursor response to erythropoietin is blunted. Inflamma tion leads to increased levels of inflammatory cytokines, including tumor necrosis factor-a. Hepcidin causes decreased iron absorption from the gastrointestinal tract and decreased iron release by macrophages by inducing internalization and proteol ysis of the transporter protein ferroportin. Item 45 Answer: D A peripheral blood smear may be normal in patients with inflammatory anemia, or, over time, may show microcytic hypochromic erythrocytes such as in iron deficiency. Typi cally, inflammatory anemia is characterized by a hemoglobin level greater than 8 gldL (80 glL). Because of erythrocyte underproduction, the reticulocyte count is typically low for the degree of anemia. The serum iron level is initially normal but decreases over time, the total iron-binding capacity is low, and the ferritin level is typically elevated. Although bone marrow evaluation is seldom neces sary, ample stainable iron would be present. However, it is not indicated for diagnosis in classic cases of inflammatory anemia. Erythropoiesis-stimulating agents may improve inflam matory anemia but are associated with thrombosis and other effects that impede safe use. Iron defi ciency would present with a low ferritin level of less than 100 nglmL (100 µglL) even in the setting of chronic inflammation. Additionally, total iron-binding capacity in iron deficiency tends to be elevated and not decreased. New onset pancytopenia in adults: a review of underlying pathologies and the associated clinical and laboratory find ings. The bone marrow biopsy demonstrating less than 10"/o cel lularity confirms the diagnosis of aplasia. The risk of progression to a clinically symptomatic disease is approximately I"lo per year. Persons with out a plasma cell dyscrasia have normal ratios; abnormal ratios suggest a disproportionate production of a monoclonal Kor 11. Patients with zero, one, two, or three risk factors have a risk of progression to clinically 187 Educational Objective: Diagnose monoclonal gammop athy of undetermined significance. Item47 Answer: C symptomatic disease over 20 years of 5%, 21%, 37%, and 58%, respectively. This patient has several findings suspicious for this disease as the cause of his hypercalcemia, including osteopenia with a thoracic compression fracture, anemia, and kidney dysfunction. However, kidney dysfunction can occur as a direct result of hypercalcemia, regardless of its underlying cause. An important clue in this patient is the discordance between the degree of proteinuria assessed by the urinalysis compared with the urine protein-creatinine ratio. A routine dipstick urinalysis will detect albumin uria but is relatively insensitive at detecting other urine proteins. However, a urine protein-creatinine ratio mea sures all proteins in the urine, including immunoglobu lins, if present. Similarly, a sulfosalicylic acid test will detect all urine proteins, including light chains, and can be performed for suspected myeloma cast nephropathy. Increased 1,25-dihydroxyvitamin D (calcitriol) lev els may result from ingestion of calcitriol or increased 25-hydroxyvitamin D (calcidiol) activation to calcitriol as a result of underlying granulomatous disease (for example, sarcoidosis) or lymphoma, thus leading to hypercalcemia. This patient has no history of calcitriol ingestion and no physical examination or radiographic features of granu lomatous disease or lymphoma. Increased calcitriol levels do not explain his anemia, osteopenia and thoracic com pression fracture, or kidney dysfunction with nonalbumin proteinuria. Primary hyperparathyroidism can present with hyper calcemia, bone mineral density loss with increased com pression fracture risk, and, when hypercalcemia is severe enough or long-standing, kidney dysfunction. However, pri mary hyperparathyroidism is uncommonly associated with anemia and does not explain the proteinuria, so measuring the intact parathyroid hormone level is not indicated. Although the patient has an extensive smoking history, no findings on physical examination or chest radio graph suggest the presence of a solid tumor. He takes chronic warfarin therapy but presents with a sig niAcant coagulopathy of unclear cause. Specific factor level measurement is useful when it is clinically helpful to under stand the basis of a coagulation disorder to guide therapy. A thrombotic microangiopathy may ensue, and schistocytes develop in 30% or patients. Factor V levels can be used to distinguish between liver disease and vitamin K deficiency. Item 50 Answer: A In addition to stopping the transfusion and resuscitating the patient. The patient is most likely experiencing sepsis as a result of transfu sion-transmitted bacterial infection. Transfusion-transminecl bacterial infection remains an important cause or transfusion-related morbidity and mortality with rates of all septic reactions and fatal septic reactions reaching 1:74,807 and 1:498. The majority or infections are due to staphylococcal species, although gram-negative organisms are also implicated. However, febrile nonhemo lytic transfusion reactions are not typically associated with hypotension. Epinephrine should only be used to treat anaphylaxis, which is less likely than sepsis in this patient. Anaphy laxis is associated with hypotension and respiratory distress, 189 Educational Objective: Treat a patient with transfu sion-transmitted bacterial infection. Considering the high morbidity and mortality associ ated with a septic transfusion reaction. Bacterial screening of apheresis platelets and the residual risk of septic transfusion reactions: the American Red Cross experience (20042006). If a 0-dimer test is not available or is positive, perform ing duplex ultrasonography would be the appropriate next step. Because this patient has none of these factors and no alternative explanation for his leg symptoms, obtaining a 0-dimer test is an appropriate next step. When using the D-dimer test for pretest probability assessments, a moderately or highly sen sitive assay should be used. Physicians must be aware of the sensitivity of the test used in local laboratories. Lower sensi tivity assays have not been validated as useful for predicting pretest probability. Patients requiring surgery should undergo transfusion before their procedure to avoid complications. Transfusion to a hemoglobin level of 10 g/dL (100 g/L) has been shown to be equivalent to exchange transfusion for low- to medium-risk surgeries. Eryth rocyte transfusions must be given with care in patients with sickle cell disease. In some patients, "hyper hemolysis" occurs because of alloimmune responses to erythrocyte antigens. Several multicenter studies have documented the clin ical efficacy of transfusion to 10 g/dL (100 g/dL) compared with the more aggressive strategy of exchange transfusion targeting a hemoglobin S level of 30%. This patient already has evidence of thrombosis and must start treatment immediately to prevent extension and embolization. Warfarin initiation alone is inadequate, because it may take 3 to 5 days to achieve a therapeutic anticoagulation effect. Possi ble point values range from Oto 8; scores of Oto 3 indicate low probability. Warfarin is avoided during pregnancy because it crosses the placenta, causes fetal anticoagula tion throughout the pregnancy, and is a teratogen. However, warfarin is not present in breast milk in any sub stantial amount and does not induce an anticoagulant effect in the breastfed infant. Similarly, heparins are minimally excreted in breast milk, and any drug ingested by an infant is unlikely to have any clinically relevant effect because of the very low bioavailability of oral heparins. Answer: E Answers and Critiques It is unknown whether apixaban, dabigatran, or rivar oxaban are excreted in human milk. Therefore, known safe alternatives to these new oral anticoagulants should be used in women intending to breastfeed. She has mul tiple myeloma requiring therapy with anemia and myelo ma-related bone disease manifested by osteopenia with a Tl2 compression fracture. Studies have shown that bisphospho nates inhibit osteoclast-mediated osteolysis, reduce the risk of skeletal-related events (pathologic fracture, need for radi ation therapy or surgery to bone, spinal cord compression), decrease bone-related pain, and improve median overall survival. The risk of skeletal-related events was reduced in patients with or without evidence of lytic bone disease on plain radiographs. Bisphosphonates therefore represent a critical aspect of care for patients with myeloma requiring therapy, and guidelines call for the use of zoledronic acid or pamidronate in all patients with newly diagnosed multiple rnyeloma. Although vertebroplasty has not been shown to be beneficial in the management of osteoporotic vertebral body compression fractures, a small randomized study comparing balloon kyphoplasty with nonsurgical man agement of painful vertebral body compression fractures in patients with multiple myeloma and solid tumors demonstrated improved short-term physical function ing, pain control, and quality of lite for those undergoing kyphoplasty. However, data on long-term outcomes with kyphoplasty are lacking in patients with cancer, and no role has been established for the procedure in the absence of pain. International myeloma working group recommendations tor the treatment of multiple myeloma-related bone disease. This is caused by erythrocyte damage through repetitive mechanical trauma such as running or marching, resulting in intravascular hemolysis. Hemolysis leads to increased levels of free hemoglobin in the plasma, which is filtered by the kidneys, resulting in hemoglobinuria. Urinalysis findings show evidence of blood in the urine by dip stick but no erythrocytes, as seen in this patient. With prolonged intravascular hemolysis, patients may become secondarily iron deficient through iron loss in the urine. Patients with this entity may show iron deficiency anemia with evidence of urine iron loss, indicated by the pres ence of hemosiderin in sloughed tubular cells by Prussian blue staining. Exercise-induced hemolysis is considered a benign condition and is treated by removal or reduction of the traumatic cause of erythrocyte injury.

The Gleason score has been correlated closely with the prevalence of nonorgan-confined disease and outcomes after definitive local therapy gastritis diet gastritis symptoms discount lansoprazole 30 mg online. This information is instru mental in guiding decisions on the need for imaging evalua tion and local therapy gastritis diet zucchini order 15 mg lansoprazole mastercard. Imaging studies to assess for possible metastatic disease or regional lymph node involvement are only indicated for men with poor-risk features (typically men with intermediate gastritis food to eat order cheap lansoprazole, high gastritis diet 7 up calories generic lansoprazole 30 mg fast delivery, or very high-risk cancer) gastritis natural supplements order lansoprazole 30 mg with visa. It is only appropriate for men with very low-risk or low-risk prostate cancer with a life expectancy of at least 10 years. Men undergoing active surveillance receive referral for definitive local therapy if there is any evidence of disease progression. As of this writing, no randomized trials have compared the use of active surveil lance with initial, definitive local therapy. Options for local therapy include external-beam radio therapy, brachytherapy, and radical prostatectomy. At the present time, there are no data supporting the use of proton beam radiotherapy in the treatment of prostate cancer. Unfortunately, no randomized trials to date have compared treatment outcomes or incidence of complications among these modalities. For men with low-risk, clinically localized prostate cancer, all three modalities offer excellent disease control. Radiation is often associated with symptoms of urinary irritation (urgency, frequency, dysuria), with brachytherapy causing these symptoms more commonly than external-beam radiotherapy. Radical prostatectomy is more commonly associated with urinary incontinence, with approximately 60% to 70% of patients having urinary leakage 2 months following surgery. Problems with sexual function are frequent in men treated with both radiation and surgery, although these complications occur more commonly follow ing surgery. Bowel complications are associated with radia tion therapy and include increased urgency, increased frequency, and diarrhea; however, these complications occur in only approximately 10% to 20% of men. Prostate cancer treatment-related complications occur most commonly in 102 the first few months after treatment, and they improve or resolve over time in most men. For all men who have com pleted local therapy, follow-up monitoring for relapse and treatment-related complications is vital. Studies have indicated that early initiation of ther apy, before identification of clinical evidence of metastasis, is associated with decreased prostate cancer mortality rates but no improvement in overall survival. As of this writing, no evidence supports one approach over the other, and consensus guidelines indicate that either is appropriate. The most common site of metastasis is bone, and men with osseous metastatic disease are at risk for pain and fracture. Treatments available to target bone metastases include external-beam radiotherapy and bone-targeted radi opharmaceutical agents. Radiation is most appropriate for men with pain limited to one or a few metastatic sites. For men with multifocal bone pain due to metastatic disease, treatment with a radiopharmaceutical agent is indicated. Another important treatment for men with osseous metastatic disease is osteoclast inhibition. In addi tion, castrate-resistant disease may be responsive to secondary endocrine therapies, including ketoconazole, megestrol, gluco corticoids, and estrogens. Both of these agents have been shown to improve overall survival in placebo con trolled trials. Sipuleucel -, an autologous dendritic cell-based T therapeutic vaccine, has also been shown to improve survival in men with asymptomatic or minimally symptomatic cas trate-resistant metastatic prostate cancer. Patients whose dis ease does not respond to these therapies or in whom disease progresses after an initial response eventually require chemo therapy. This combination has been found to improve survival compared with mitoxantrone, which was the standard of care previously. Cabazitaxel is a newer taxane that also has demonstrated efficacy in the treatment of metastatic castrate resistant prostate cancer. Although chemotherapy is effective in patients with advanced prostate cancer, the median survival of such patients is less than 2 years. Given this prognosis, the use of chemotherapy in the setting of metastatic castrate-resistant prostate cancer should be discussed within the context of goals of care and palliative care. Testicular cancer management represents a true success story among solid tumors because it has been one of the most curable cancers since the late 1970s. The 5-year sur vival rate for all patients with testicular germ cell tumors is approximately 95%. Mostly all testicular cancers are germ cell tumors, which will be discussed in this section. For most men, testicular cancer symptoms are attributable to local disease and include testicular swelling, identification of a testicular mass, or, occasionally, a dull pain in the lower abdo men, perianal region, or scrotum. After a palpable mass is identified, testicular ultrasonog raphy is performed to confirm the presence of a solid mass, following which radical inguinal orchiectomy is usually per formed. Needle biopsy is contraindicated, as this can result in an increased recurrence rate. In conjunction with histologic sampling, it is important to measure serum tumor marker levels, which include P-human chorionic gonadotropin, lactate dehydrogenase, and a-fetoprotein. The serum a-fetoprotein level is never elevated in patients with pure seminomas, and P-human chorionic gonadotropin is only elevated in approximately 20% of patients with pure semino mas. Nonseminomatous germ cell tumors can contain ele ments of seminoma, but those elements are mixed with tumors with nonseminomatous histologies, which include yolk sac tumor, choriocarcinoma, and embryonal carcinoma. Treatment depends on stage, histology, and, in patients with advanced disease, risk assessment based on disease extent and tumor marker levels. Because many testicular can cer treatments can affect future fertility, obtaining a sperm Testicular Cancer · Patients with a biochemical recurrence of prostate can cer (a rising serum prostate-specific antigen level and no evidence of local disease progression) are treated with androgen deprivation therapy. For patients with seminoma confined to the testis (stage I), orchiectomy is usually curative. Options following surgery include active surveillance, single-agent carboplatin, and radi ation to para-aortic lymph nodes. Active surveillance consists of regular tumor marker and imaging assessments with the purpose of evaluating for evidence of recurrence. Treatment of advanced disease depends on both histology and risk assessment based on clinical extent of disease and tumor marker levels. All patients with advanced disease receive chemotherapy, most commonly bleomycin, etoposide, and cisplatin, given for three to four cycles. Following treatment, patients are observed closely with periodic history, physical examination, and imaging and tumor marker assessments. For patients with residual radio graphic abnormalities following treatment, surgery is some times recommended. Patients with relapsed or refractory disease are treated with salvage chemotherapy, and some times, autologous hematopoietic stem cell transplantation. There is an increased risk for metabolic syndrome (insulin resistance, hypertension, dyslipidemia, abdominal obesity) after chemotherapy or radia tion treatment. Other potential complications include pulmo nary toxicity, kidney failure, peripheral neuropathy, ototoxicity, Raynaud phenomenon, and cardiovascular disease. Renal cell carcinomas arise in the renal cortex and are the most common type of tumors affecting the kidney. The next most common tumor, transitional cell carcinoma of the renal pelvis, is not considered a renal cell carcinoma and is treated similarly to bladder cancer. Patients with renal cell carcinoma are often asymptomatic until they have advanced disease, but possible symptoms include hematuria, an abdominal mass, abdominal pain, and unexplained weight loss. However, the classic triad of flank pain, hematuria, and a palpable abdomi nal mass occurs in only approximately 9% of patients. Larger lesions can be removed without biopsy if imaging findings are consistent with malignancy. For patients who are not surgical candi dates, active surveillance or ablative treatment can be consid ered for those with small tumors. No established adjuvant therapy for renal cell carcinoma is available, although studies using targeted agents are ongoing; consequently, patients with localized renal cell carcinoma are observed following surgery regardless of the local extent of disease. Selected patients with metastatic disease at presentation undergo cytoreductive nephrectomy, which has been associated with improved sur vival in some studies. Common sites of metastasis in renal cell carcinoma are the lung, liver, bone, and renal fossa. Previously, metastatic renal cell carcinoma treatment was disappointing because responses to cytotoxic chemo therapy were limited and survival was often short. Although interleukin-2 can result in long-term remission in about 10% of patients, this agent is expensive, not widely available, and is associated with significant toxicity. However, because of rapidly expanding knowledge about the molecular pathogen esis of renal cell carcinoma, multiple targeted therapies are now available, and many of these agents have been shown to have significant activity against renal cell carcinoma. Unfortunately, no stud ies comparing any of these agents have been published to date. Agents with demonstrated activity in second-line treatment include axi tinib, sorafenib, and everolimus. Following resection, additional treatment with intravesical bacillus Calmette-Guerin or chemotherapy is usually given, with the amount of treatment determined by risk assessment. The risk of recurrence and of new primary tumors is high fol lowing a diagnosis of superficial bladder cancer; consequently, careful surveillance is essential following initial treatment. Cystectomy is recommended only for patients with frequent, high-grade recurrences occurring within a short period. Conversely, patients with muscle-invasive disease often are treated with radical cystectomy, although bladder sparing approaches can be considered in some patients. Neoadjuvant cisplatin-based chemotherapy is also recom mended, as it can improve survival in patients with muscle invasive disease; however, the role of adjuvant chemotherapy is much less clear. Although cisplatin-based regimens have been shown to improve survival, cures are uncommon, and median survival is only about 15 months. In the United States, almost all bladder cancer is transitional cell carcinoma, which will be the focus of this sec tion. The incidence of bladder cancer has increased by more than 50% during the past 20 to 30 years. Risk factors include advanced age, white ethnicity, various occupational exposures, and cigarette smoking; smoking is the most important risk factor and encompasses current and former smokers and indi viduals exposed to second-hand smoke. Individuals at occupa tional risk include metal workers, painters, miners, textile workers, and leather workers, among others. The most common presenting symptom is painless hema turia, although some patients experience other urinary symp toms, such as frequency, urgency, or dysuria. Identification of new-onset hematuria in patients older than 40 years man dates urologic evaluation with cystoscopy. Biopsy or resection can be performed during initial cystoscopy, depending on the status of the lesion. These lesions often can be treated Bladder Cancer · the response of metastatic renal cell carcinoma to tradi tional cytotoxic chemotherapy is limited and associated with short survival; however, multiple targeted thera pies, including vascular endothelial growth factor inhibitors, have significant activity against renal cell carcinoma and may improve survival in select patients. Transient palpable lymphadenopathy is a common physical finding, particularly among young patients, and is virtually always benign, with less than 1% of cases persisting and later found to be lymphoma. Local or systemic infection with bac teria or viruses, drug reactions, and autoimmune disease can all be characterized by transient lymphadenopathy. Lymphoma is the most common subtype of the hemato logic malignancies and is heralded by lymphadenopathy. The fifth most common malignancy, lymphoma constitutes 5% of all cancers and 3% of cancer-related deaths in the United States. Hodgkin lymphoma has a bimodal age distribution, occurring between ages 15 and 45 years and after age 55 years. In addition to chronic inflammation caused by infectious agents, genetic factors and occupational risk factors predis posing to lymphoma include exposure to herbicides, chlorin ated organic compounds, and other fertilizing material used in farming. To establish a diagnosis of lymphoma, it is optimal to per form an excisional biopsy to preserve lymph node architecture. Core needle biopsy can be used for deep lymph nodes in place of excision, but fine-needle aspiration should be avoided. Routine blood tests should include a complete blood count with differential, eryth rocyte sedimentation rate, and chemistry panel, including serum urate levels. Serum levels of lactate dehydrogenase, p2microglobulin, and immune globulins should also be assessed to assist in diagnosis and establish prognosis. Patients with aggressive lymphoma with involvement of the testes, sinuses, bone marrow, and ocular sites require a lumbar puncture owing to an increased risk for central nervous system involvement. A comprehensive physical exami nation determines the number of sites, size (small versus large), and consistency (firm and fixed versus soft and move able) of lymphadenopathy. In addition, careful assessment for enlarged Waldeyer tonsillar ring nodes and hepatic and splenic enlargement is warranted. Patients with soft, small, freely moveable lymph nodes that are limited to one or two adjacent sites and who have no other significant history or physical examination findings can be followed with serial examina tions over 6 to 8 weeks and require no other laboratory studies or imaging. Persistent or enlarging lymphadenopathy, particu larly when associated with systemic symptoms, may require Evaluation and Diagnosis · In addition to chronic inflammation caused by infec tious agents, genetic factors and occupational risk fac tors predisposing to lymphoma include exposure to herbicides, chlorinated organic compounds, and other fertilizing material used in fanning. Lymphomas are classified into three prognostic groups: indolent, aggressive, and highly aggressive. Conversely, aggressive lymphomas, and particularly, highly aggressive lymphomas such as Burkitt oo. Newer modalities of prognostic testing are available, including next-generation sequencing that assesses major portions of tumor genomes to identify mutations predictive of outcome to available therapies.
