血吸虫病性大肠癌的组织学分型与虫卵的关系──147例大肠癌的分析

HISTOPATHOLOGIC SUBTYPES OF COLORECTAL CARCINOMA WITH AND WITHOUT SCHISTOSOMIASIS AND ITS RELATIONSHIP TO OVA DEPOSITION──ANALYSIS OF 147 CASES

本文对本院８５例血吸虫病合并大肠癌和６２例无合并症的大肠癌进行了组织学分型差异的比较，并与血吸虫卵沉积严重程度联系起来。结果发现血吸虫病合并大肠癌中粘液性癌的比例明显高于对照组，这种差异在虫卵中度～高度沉积的大肠癌中更为显著，提示了血吸虫病合并大肠癌中虫卵沉积程度越高组织学分型特异性越大，这种特异与慢性溃疡性结肠炎合并癌的病例有类同之处。

Comparison of histopathologic subtype was made between 85 cases of colorectal carcinoma with schistosomiasis(group CCS) and 62 cases without complication(group CC), and between the degree of ova deposition. It was found that there was higher percentage of mucinous carcinoma in group CCS than in group CC, and was also much moresignificantly higher in the cases of moderate and severe ova depositon. Similar characteristics of histologic subtypes have been found in colorectal carcinoma associated with chronic ulcerative colitis.
