食管癌是我国常见的恶性肿瘤之一。有关影响食管癌予后的因素报告较多。但对食管癌肿瘤内脉管侵袭的研究却少有报告,尤其对术前放射治疗切除标本肿瘤内脉管侵袭的观察更少。本文对135例食管癌切除标本(其中32例为术前放疗标本)进行脉管侵袭的观察。探讨放射治疗对肿瘤内脉管侵袭的影响以及脉管侵袭与肿瘤的大小,肿瘤的部位、组织学分化程度,淋巴结转移及癌周间质反应的关系。材料和方法 1975—1984年我院共切除食管癌135例(其中术前放疗32例)作为分析材料。所有标本均按肿瘤标本常规取材、福尔马林固定、石
Esophageal cancer is one of the common malignant tumors in China. There are many reports of factors affecting esophageal cancer. However, studies on vascular invasion in esophageal cancer have rarely been reported, and even fewer observations have been made on preoperative vascular invasion of tumor specimens. In this study, vascular invasion was observed in 135 specimens of esophageal cancer (32 of which were preoperative radiotherapy specimens). To investigate the effect of radiotherapy on vascular invasion in tumors and the relationship between vascular invasion and tumor size, tumor location, histological differentiation, lymph node metastasis, and interstitial stromal response. Materials and Methods From 1975 to 1984, a total of 135 cases of esophageal cancer (including 32 cases of preoperative radiotherapy) were resected as analysis materials. All specimens were routinely obtained from tumor specimens, formalin fixed, and stone
