早在1898年日本金森首先发现日本血吸虫病与直肠癌合并存在的事实,1932年美国学者 Snell 在我国苏州的报告可能是我国最早的资料。1949年以来,国内络续有病理学家及临床医师的病例报告及讨论。以后,血吸虫病流行地区如苏州和嘉兴有较大数字的病例分析与病理形态学观察报告。关于两者之间的关系,大多数学者认为有一些因果关系,近年来更认为血吸虫性大肠病变是一种大肠癌癌前病变。其理由如下。
As early as 1898, Japan’s Kanamori first discovered the existence of schistosomiasis and rectal cancer in Japan. In 1932, American scholar Snell’s report in Suzhou, China may be the earliest data in China. Since 1949, there have been case reports and discussions with pathologists and clinicians in China. Later, schistosomiasis epidemic areas such as Suzhou and Jiaxing have a large number of case analysis and pathological observations. Regarding the relationship between the two, most scholars believe that there are some causal relationships. In recent years, schistosomes-related colorectal disease is considered to be a precancerous lesion of colorectal cancer. The reason is as follows.
