本文通过对100例直肠癌术后标本(未放疗组及放疗组各50例)的病理组织学检查,眼观界线下0.5～3.0cm均在粘膜下、肌层、浆膜或肌层外脂肪不同部位发现有癌侵润或扩展的(?)2例。其中未放疗组16例,放疗组26例。观察结果折算为新鲜标本之距离。分析结果表明:放疗与未放疗组差别显著(P<0.05)。通过原始数据计算结果,放疗对此距离影响较大(即使之缩小)。浸润与逆向扩展与侵犯肠管的周径;大体及组织学类型及Dukes分期有关,而与肿瘤大小无关。本文对于临床如何根据术前检查来判断能否保留括约肌或采用什么术式提供了比较具体的参考意见。并指出:放疗病人(剂量3000～(?)000rads)切缘与癌体下缘距离比末放疗病人可适当缩短。由此扩大了保留括约肌手术范围。
This article through the pathological examination of 100 cases of rectal cancer after surgery (not radiotherapy group and 50 cases of radiotherapy group), 0.5 to 3.0 cm below the eye line are in the submucosa, muscle, serosa or extramuscular fat Two cases with cancer invasion or expansion (?) were found in different sites. There were 16 patients without radiotherapy and 26 with radiotherapy. The observations are converted into fresh specimens. The analysis showed that there was a significant difference between radiotherapy and non-radiotherapy groups (P<0.05). From the results of the raw data calculation, radiotherapy has a large influence on this distance (even if it is reduced). Infiltration and continuation of expansion and violation of the perimeter of the bowel; gross and histological types and Dukes staging, but not with the size of the tumor. This article provides a more specific reference on how to determine whether the sphincter muscle can be preserved or what type of surgery is used according to the preoperative examination. And pointed out: radiotherapy patients (dose 3,000 ~ (?) 000rads) and the lower edge of the cancer than the end of radiotherapy patients can be appropriately shortened. This expands the scope of surgical sphincter preservation.
