贲门癌口侧浸润距安全切断线的判定

目的　探讨贲门癌根治术中上切断线的判定。方法　通过对 70例施行根治性手术的贲门癌口侧浸润距离的测量及其与病理因素关系分析 ,判定安全切断线。结果　贲门癌口侧浸润距离与其病理因素密切相关 (P<0 .0 5 )。结论　癌灶 <3cm ,早期及 Borrmann2、3型、高分化、团生、浆膜层未受侵时 ,上侵长度在 2 cm以内 ,安全切断线可在 3cm以内。而>3cm、Borrmann3、4型、低分化、弥漫生长、浆膜受侵者 ,上侵长度为 2～ 4cm左右 ,安全切线应在 5 cm以上。

Discussion on Decision of Safe Cut Line from Oral Invasive Length of Gastric Cardiac Adenocarinoma

Objective To discuss decision of safe cut line radical gastrectomy of cardiac adenocarcinoma.Methods The oral invasive length of 70 cases gastric ca rdiac adenocarcinoma underwent radical gastrectomy were measured, and the relati onship between it and pathological factors was analyzed.Results Oral invasive length of gastric cardiac adenocarcinoma had a significant difference between th e groups in different pathological factors.Conclusions Safe cut line probably be less than 3 cm in those that the size was smaller than 3 cm, e arly stage, Borrmann l?2 type, well differentiated, expend growth patten and wi thout serosal invasion. However,it should be more than 5 cm in those that the si ze was larger than 5 cm,Borrmann 3?4 type, poorly differentiated, diffuse grow th patten and w ith serosalinvasion.
