• A 66-year-old black woman diagnosed with stage III colon cancer underwent definitive resection of the primary tumor 3 years ago. After surgery, she received adjuvant chemotherapy with 5-fluorouracil and leucovorin. Approximately 20 months later, she developed metastatic disease in the liver (five lesions in right and left lobe) and lungs (one lesion in the right and left lobe). She was treated with irinotecan, 5-fluorouracil, and leucovorin, and had a partial response to therapy. One month ago, disease progression was documented on restaging CT scans. The patient‟s laboratory studies show relatively normal organ function. She has fatigue, decreased appetite, and has noticed a 2.3-kg (5-Ib) weight loss over the past 3 months. She has stopped participating in weekend bike trips with a cycling club, but remains involved in church and family activities and states that she wants to be as aggressive as possible in fighting the cancer. What is the most reasonable recommendation for this patie
• A 72-year-old man is evaluated because of constipation, abdominal pain, and distention that have worsened over the past week. Two years ago, he was diagnosed with stage III rectal cancer (primary tumor and renal involvement) and underwent low anterior resection. Chemotherapy with 5-fluorouracil and leucovorin followed, and pelvic radiation was given with concurrent infusion of 5-fluorouracil. He has been having regular bowel movements, and results of his most recent colonoscopy (1 year ago) were unremarkable. On physical examination, his pulse rate is 100/min. He has orthostatic hypotension, a slightly distended abdomen with hyperactive bowel sounds, and some guarding to deep palpation in the left lower quadrant. Plain radiograph of the abdomen shows distended loops of small bowel, with no stool in the distal colon or rectum. The patient is hospitalized for bowel rest and intravenous hydration. What is the next step in this patient‟s management?
• A 63-year-old man is evaluated because of a several-month history of increasing fatigue and some vague upper abdominal discomfort. His medical history includes gastroesophageal reflux disease, coronary artery disease, and clinical depression, all of which are well controlled with medications. The patient has been working full time. On physical examination, he has mild hepatomegaly. His hemoglobin is 12.2 g/dL, serum alkaline phosphatase level 280 U/L, and serum aspartate aminotransferase level 65 U/L. CT scan of the abdomen and pelvis shows multiple hepatic lesions ranging in size from 1 cm to 4 cm; mesenteric, para-aortic, and paracaval lymphadenopathy, and a colonic mass at the splenic flexure. Colonoscopy reveals a nonobstructing, non bleeding lesion; biopsy shows it to be poorly differentiated adenocarcinoma. Fine- needle aspiration of one of the liver lesions confirms the presence of malignant cells consistent with a primary colon cancer. What is the most appropriate next step in
• A 64-year-old woman has the following family history: One sister, who was a smoker, had lung cancer at the age of 63 years; another sister had breast cancer at the age of 70 years. Her father had prostate cancer at 82 years of age, and her mother had breast cancer at age 71 years. She has three other sisters, now aged 58, 60, and 65 years who have no history of cancer. She has two daughters and two sons between the ages of 25 and 39 years, who have no history of cancer. Her ancestry is European in general, and she is not of known Ashkenazi Jewish descent. She is concerned that “cancer runs in the family” and would like to have one of those “gene tests” she has read about. What is the best advice to give her and her family?

• A 26-year-old man with testicular cancer who is receiving chemotherapy is evaluated in the emergency department. His temperature is 38.9 °C (102 °F), and he complains of feeling flushed and tired. He has an indwelling central venous port, but there are no localizing symptoms to suggest a source of infection. Chest radiograph shows no abnormalities. The patients hemoglobin is 8.9 gIdL; the absolute neutrophil count is 165/μL and the platelet count is 56,000/μL. Results of other laboratory studies and urinalysis are within normal limits. Blood samples are obtained from a peripheral vein and through the port and sent for culture; a urine culture is also ordered. The patient is hospitalized and intravenous ceftazidime is initiated. Three days later, the patient‟s temperature is 37.8 °C (100 °F) and absolute neutrophil count is 4504/μL; his clinical condition is otherwise stable. Results of blood and urine cultures are negative. A repeat chest radiograph is normal, and blood and urine speci
• A 68-year-old man presents to his primary care physician for a routine physical examination. The patient‟s medical history is significant for hypertension. The patient is found to have guaiac-positive stools and is subsequently referred for colonoscopy. Colonoscopy reveals a “golf ball”-size, near-obstructing tumor in the descending colon, not admitting the scope. The biopsy is positive for adenocarcinoma of the colon. Which of the following is the next step in the management of this patient?
• A 57-year-old man is found to have a rectal mass 3 cm from the anal verge on digital rectal examination. Subsequent colonoscopy and biopsy confirm rectal adenocarcinoma. EUS examination demonstrates penetration of the tumor into, but not through, the muscularis propria, but shows significant perirectal lymph nodes. CT scan of chest/abdomen/pelvis demonstrates no metastases. The patient is staged as T2N1M0. What procedure should be attempted to remove the primary lesion in this patient?
