R.T. is a 64-year-old man who went to his primary care provider's office for a yearly examination. He initially reported having no new health problems; however, on further questioning, he admitted to having
developed some fatigue, abdominal bloating, and intermittent constipation. His physical examination
findings were normal except for stool positive for occult blood. He had a complete blood count (CBC) with
differential, basic metabolic panel (BMP), and carcinoembryonic antigen (CEA) testing and was referred
to a gastroenterologist for a colonoscopy. Colonoscopy revealed a 5-cm mass in the sigmoid colon, which
was diagnosed as adenocarcinoma of the colon. A distant metastatic workup is negative, and R.T. is being
scheduled for a laparoscopic sigmoidectomy with anastomosis.
