An endoscopic biopsy was performed on specimens taken from 374 patients with a large bowel cancer, who had received a colo-rectal resection between 1980 and 1984. An average of three to four biopsy specimens was taken from each patient. The pathological diagnosis of these specimens revealed a carcinoma with an identifiable pathological classification in 280 patients (74.9%), a carcinoma without an identifiable classification in 54 (14.4%), a suspect cancer in 7 (1.9%), and no sign of a cancer in 33 (8.8%). The diagnosis of the 33 cases in which no cancer was detected were adenoma in 11 patients, inflammation in 8, necrosis in 1, and no clear pathological determination in 11. The correspondence rates between a biopsy specimen and a tissue specimen diagnoses were 57.9% in a well differentiated adenocarcinoma; 77.4% in a moderately differentiated adenocarcinoma; 85.5% in a poorly differentiated adenocarcinoma; and 100% in a mucoid carcinoma.
对1980年至1984年间接受结直肠切除术的374例大肠癌患者的标本进行了内镜活检。每位患者平均采集三到四个活检标本。这些标本的病理诊断显示，280例患者（74.9%）为具有可识别病理分类的癌，54例（14.4%）为无可识别分类的癌，7例（1.9%）为疑似癌，33例（8.8%）无癌症迹象。在未检测到癌症的33例病例中，诊断为腺瘤的有11例患者，炎症的有8例，坏死的有1例，11例无明确病理诊断。活检标本与组织标本诊断的符合率在高分化腺癌中为57.9%；中分化腺癌中为77.4%；低分化腺癌中为85.5%；黏液癌中为100%。
