The morphological study of surgical specimens in rectal cancer involves assessment of the quality of mesorectumectomy, examination of serial sections of a tumor growth area, and study of the proximal, distal, and circulatory ends of resection as a criterion for the quality and efficacy of surgery. The circulatory end of resection is regarded as positive when it has tumor cells inside or within 1 mm of it and the performed surgery is unradical. The data obtained with the use of this technology make it possible to most fully estimate the site and extent of a tumor process, to identify a number of important prognostic factors, and to assess the quality of a performed surgical intervention and preoperative diagnosis. The procedure is adapted to the standard technological equipment of morbid anatomy units.
直肠癌手术标本的形态学研究包括评估直肠系膜切除的质量、检查肿瘤生长区域的连续切片，以及研究切除的近端、远端和切缘作为手术质量和疗效的标准。当切除切缘内或距切缘1毫米范围内有肿瘤细胞时，该切缘被视为阳性，所施行的手术为非根治性手术。使用该技术获得的数据能够最全面地评估肿瘤进程的部位和范围，识别一些重要的预后因素，并评估所施行的手术干预和术前诊断的质量。该程序适用于病理解剖科室的标准技术设备。
