大肠是多原发癌好发部位之一,在大肠内同时或先后发生二个或二个以上的原发癌灶为大肠多原发癌。任何一个外科医生的临床实践中,都不可能亲自遇到和处理很多次大肠多原发癌(以下简称多发癌),因此常对本病认识不足,而把注意力集中到一个癌灶上容易漏掉同时存在的第二个癌灶或把后来发生的原发癌误为“复发”或转移判为不治之症而放弃治疗,因此大肠多发癌值得引起注意。
The large intestine is one of the most prevalent sites of primary cancer. Two or more primary tumors occur simultaneously or sequentially in the large intestine as multiple primary tumors of the large intestine. In any clinical practice of a surgeon, it is impossible to personally encounter and deal with many multiple primary large intestine cancers (hereinafter referred to as multiple cancers), so the lack of knowledge of the disease is often enough to focus on one cancer site. It is worth noting that multiple cancers in the large intestine are missed if they miss the second cancerous tumor that exists at the same time or mistaken the subsequent primary cancer for “recurrence” or metastasis is rendered incurable.
