• Which one of the following statements is true of B cell CLL?
• A 29-year-old man was diagnosed with stage II (that is, spread from the primary tumor to retroperitoneal lymph nodes) nonseminomatous germ cell tumor 1 year ago. Treatment included orchiectomy and retroperitoneal lymph node dissection. He now presents with an elevated level of β-human chorionic gonadotropin hormone and multiple pulmonary lesions ranging in size from 0.61 to 3.22 cm. Needle biopsy specimen of the largest lesion reveals a germ cell tumor consistent with the initial diagnosis. He is asymptomatic. What is the best treatment for this patient?
• Radiation-induced cell death in carcinomas typically occurs immediately after attempting to traverse which phase of the cell cycle?
• A 30-year-old man presented with a swelling in the testis and an ultrasound scan confirmed the presence of a malignant mass. Following orchidectomy, he was found to have a 40-mm seminomatous germ cell tumour without non-seminomatous components. There was evidence of vascular invasion within the testis.Investigations: serum lactate dehydrogenase (LDH) 1250 U/L (10–250) serum α-fetoprotein normal serum β-human chorionic gonadotrophin (HCG) 700 U/L (<5) A CT scan of body showed retroperitoneal lymphadenopathy of up to 7 cm in size, a 3- cm mediastinal lymph node and over 30 pulmonary metastases. There were no signs of liver, brain or bone metastases. What is the most appropriate International Germ Cell Cancer Collaborative Group classification?
• A 43-year-old man with severe acquired aplastic anemia has not responded to immunosuppressive agents. He remains neutropenic and transfusion-dependent for platelets and red cells. He has an HLA-identical brother who has been cleared as a donor for his planned allogeneic stem cell transplant.They are both cytomegalovirus-seronegative. Which of the following would be prevented by using irradiated cellular blood products for this patient?
• In an office visit for an annual checkup, a 46-year-old man reports that he has had malaise and intermittent sweats for the past few months but has been able to continue his job as a high school teacher. Two years ago he was treated for stage III diffuse large-cell non-Hodgkin‟s lymphoma with six cycles of cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) and attained complete remission. He takes simvastatin for hypercholesterolemia and hydrochlorothiazide for hypertension. On physical examination, he has lymphadenopathy: a 3-cm right axillary node and a 2- cm right supraclavicular node. His spleen tip is palpable. Laboratory evaluation shows mild normochromic, normocytic anemia and an elevated serum lactate dehydrogenase level. CT scans of his chest and abdomen reveal additional mediastinal and retroperitoneal lymphadenopathy. What is the best next step in this patient‟s management?
• A 68-year-old man with locally advanced non-small-cell lung cancer is evaluated because of the new onset of low back pain over the past 2 weeks. It is relieved with ibuprofen, and his only other symptom is mild fatigue. The patient completed combined chemotherapy and radiation therapy 6 months ago, and restaging scans afterward showed marked shrinkage of the right perihilar mass. He has no muscle weakness. Plain radiograph of the thoracic and lumbar spine shows no abnormalities other than signs of mild osteoarthritis. Neurologic examination is unremarkable. What is the most appropriate next step in the management of this patient?
• A 71-year-old man with mild chronic obstructive pulmonary disease and mild hypertension is evaluated during an annual routine visit. Review of systems is notable for intermittent cough, increasing dyspnea on exertion, a 2.3-kg (5 Ib) weight loss, and fatigue. The patient takes aspirin, 81 mg/d, and hydrochlorothiazide, 50 mg/d orally. He smoked one pack of cigarettes per day for 49 years but quit smoking 2 years ago. On physical examination, distant breath sounds are audible in both lungs and there are scattered rhonchi. Chest radiograph shows a perihilar mass. Abnormal laboratory results include hemoglobin of 12.5 g/dL and a serum sodium of 127 meq/L. Endobronchial biopsy reveals small-cell lung cancer. Further staging studies suggest that the disease is limited-stage. What is the most appropriate treatment for this patient‟s hyponatremia?
• A 58-year-old woman with a 60-pack-year smoking history is evaluated because of hemoptysis and weight loss. Chest radiograph and CT scan show a right perihilar mass with mediastinal adenopathy. The results of CT scans of the abdomen, bone scan, and MRI of the head are otherwise negative. Examination of a specimen by bronchoscopic biopsy confirms small-cell lung cancer, and the findings suggest limited-stage disease. After the patient completes mediastinal radiation therapy and four cycles of cisplatin and etoposide, repeat CT scans indicate that her disease is in complete remission. What is the best recommendation concerning further therapy?
• A 61-year-old man with a 120-pack-year smoking history is evaluated for a persistent and worsening cough and found to have a 3-cm mass in the right upper lobe on chest radiography. CT-directed needle biopsy is positive for squamous cell carcinoma. CT scans of the abdomen and pelvis, bone scan, and MRI of the head are negative for metastatic disease. Positron emission tomography scan shows uptake only in the right upper lobe mass, and pulmonary function tests indicate that the patient has adequate pulmonary reserve to undergo resection. The patient undergoes a right upper lobectomy. All margins are clear, and all peribronchial lymph nodes are negative for tumor within the resected specimen. What is the most reasonable adjuvant therapy for this patient?
