摘要
本文报道30例胃十二指肠血吸虫病合并胃癌,均为手术病理证实。主要从组织学方面进行分析。其中胃窦部28例窦贲门部2例。癌灶处虫卵沉积为33.3％(10/30),十二指肠切缘处为66.7％(20/30)。虫卵均已钙化。癌灶处虫卵周围未见癌变的移行过渡现象,故虫卵诱发癌肿之说,证据不足。十二指肠处虫卵周围无特异性变化,提示十二指肠并未因虫卵沉积而使癌肿发生率增多。推测虫卵只有在其它因素参与下才有可能诱发癌肿。因胃血吸虫病与胃癌的好发部位相同,二者关系有待进一步探讨。十二指肠血吸虫病合并胃癌可认为是偶然并存。
Thirty cases of gastric and duodenal schistosomiasis associated with gastric carcinomas (28 pyloric, 2 cardia) are reported. On histological sections, ova of the parasite were found deposited in cancerous tissue in 10, at periphery of cancer in 20. All of the ova seen were calcified. No transitional zone was observed in between the ova and cancerous foci, nor was there any specific histologic changes around the ova. The authors concluded that there was no evidence indicating that gastric carcinoma can be induced by schistosomiasis. The association of schistosomiasis and gastric carcinoma was merely coincidental.
