A 63-year-old man presents to his primary care doctor with a one-month history of blood in his stools. He is referred for a colonoscopy and found to have a friable mass along the anterior wall just proximal to the second rectal fold. A biopsy confirms moderately-differentiated adenocarcinoma. The patient then obtains pelvic magnetic resonance imaging and chest, abdomen, and pelvis computed tomography demonstrating local invasion of the primary tumor into the mesorectal fat (T3), no suspicious regional lymph nodes (N0), and no evidence of distant metastatic disease (M0).
一位 63 岁男性因一个月来大便带血到其初级保健医生处就诊。他被转介进行结肠镜检查，发现前壁靠近第二直肠折处有一个易碎的肿块。活检证实为中分化腺癌。随后，患者进行了盆腔磁共振成像和胸部、腹部及盆腔计算机断层扫描，显示原发肿瘤局部侵犯中直肠脂肪（T3），无可疑区域淋巴结（N0），也无远处转移疾病的证据（M0）。
