• A 40-year-old woman has a routine gynecologic examination. At the age of 32 years, she gave birth to twins after receiving fertility drugs. She has just seen a television program on ovarian cancer, and is concerned because previous use of fertility drugs and a family history of ovarian cancer were mentioned as possible risk factors. Her mother developed endometrial cancer at 56 years, and a paternal uncle was diagnosed with a type of lymphoma at 60 years. She has one older sister with hypertension and one younger brother who is healthy. Results of her pelvic examination are unremarkable, but she asks what additional tests she should have to look for ovarian cancer in the early stages that cannot be detected by physical examination. What is the most appropriate management for this patient?
• A 30-year-old woman has a right mastectomy and axillary lymph node dissection for a carcinoma diagnosed by fine needle aspiration cytology. The histologic pattern is that of a poorly differentiated carcinoma that is negative for oestrogen and progesterone receptors, but is positive for HER2/neu. One axillary lymph node demonstrates micro- metastases. Her 32 year old sister is found to have a similar lesion. Which of the following statements regarding risk factors for this lesion is the most appropriate?
• A 50-year-old perimenopausal woman is evaluated because of abdominal swelling. CT scan of the chest, abdomen, and pelvis shows mesenteric lymphadenopathy and a small amount of ascites but no ovarian masses. Needle biopsy specimen shows adenocarcinoma; the tumor is found to be negative for hormone receptors. The serum carcinoembryonic antigen level is normal at 2.0 ng/mL and the serum CA-125 is 1200 ng/mL (elevated). What is the best next step in her treatment?
• 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?
• Diffuse intramural spread with extensive fibroblastic thickening is a morphologic pattern most characteristically associated with carcinoma of the
• 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?
• Which of the following stages of oropharyngeal squamous cell carcinoma is associated with the lowest risk of contralateral cervical lymph node metastases?
• 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?
• For previous patients, after the appropriate evaluation, the patient undergoes surgery. No intraoperative evidence of metastases is identified. Postoperatively, the pathology report reveals that the tumor is an adenocarcinoma invading into the pericolonic fat, with 2 involved lymph nodes. After the patient recovers from surgery, which of the following is the most appropriate next step in his management?
• A 43-year-old man presented with vomiting and 4-kg weight loss. His performance status was 1. He was found to have a pre-pyloric gastric carcinoma gastric outlet obstruction. A CT scan showed no metastases. What is the most appropriate next step?
