• 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?
• 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?
• Patient with germ cell tumor receiving BEP. Which side-effect would necessitate cessation of the responsible drug:
• In a case of Dysgerminoma of ovary tumor markers is likely to be raised.one of the following
• Young male with germ cell cancer. He is on bleomycin. etoposide and cisplatinum. What side effect would make you stop the treatment?
• 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?
• A 68-year-old man with a 60-pack-year smoking history is evaluated because of hemoptysis. Radiograph of the chest shows a right hilar mass and mediastinal widening. CT scans of the chest and abdomen confirm the hilar mass and bulky lymphadenopathy in the mediastinum with no other overt metastases. Bronchoscopic biopsy specimen shows small-cell lung cancer. Bone scan and CT scan of the head are negative for tumor. A low serum sodium level and inappropriately high urine osmolality suggest that he has the syndrome of inappropriate antidiuretic hormone secretion. Which of the following is the most appropriate treatment recommendation?
• During evaluation of tumor biopsy specimens, which of the following markers can be used as a histochemical indicator of cell proliferation?
• A 52-year-old woman who is a nonsmoker has a 3-cm right inguinal lymph node.Biopsy specimen shows a poorly differentiated malignancy that is difficult to characterize by light microscopy. The biopsy specimen is negative for leukocyte common antigen, cytokeratin, and estrogen receptors. Which of the following additional tests would best establish the source of this tumor?
• Mutations in which gene are least likely to be associated with breast cancer if inherited in the germ-line?
