Malignancy- A 64-year-old woman with a history of cervical intraepithelial neoplasia presents with a firm 3-cm mass protruding at the anal verge. Anoscopy shows a fixed mass just distal to the dentate line. A biopsy of the lesion is performed, which has the findings shown in the Figure. Colonoscopy findings are unremarkable and computed tomography of the chest, abdomen, and pelvis reveals no evidence of distant disease. Magnetic resonance imaging reveals no locoregional nodal or sphincter involvement. The next best step in management for this patient is:
- A 64-year-old woman undergoes colonoscopy for a positive fecal immunochemical test result. A mass is found in the midrectum (Figure). Pathology findings show an adenocarcinoma. For local staging of the tumor, what is the most appropriate next study to perform?
Malignancy- A 70-year-old woman with a medical history of hypertension and hypothyroidism reports rectal bleeding, maroon blood mixed in with her stool, and weight loss to her primary care physician. She is referred to undergo diagnostic colonoscopy. She is found to have a hepatic flexure mass with biopsies taken and tattoo placed distally, with pathology returning as moderately differentiated adenocarcinoma, mismatch repair (MMR) protein expression intact. Laboratory testing includes a complete blood count, basic chemistry, and carcinoembyronic antigen (CEA) with findings of anemia and a mildly elevated CEA level. What imaging is recommended for completion of the staging work-up in this patient?
- A 57-year-old man undergoes total neoadjuvant therapy (TNT) for management of a cT3N1M0 rectal cancer. After completion of both chemotherapy/radiotherapy and consolidation chemotherapy, the presence of complete clinical response to treatment is assessed by
