We investigated the occurrence of multiple primary colorectal and gastric cancer (MPCGC) in 1277 colorectal cancer patients between 1972 and 1996. MPCGC was found in 65 (5.1%). In the 28 synchronous cases, gastric or colorectal cancer was accidentally detected by pre-, intra-, or postoperative examinations. In 23 of the 37 metachronous cases, colorectal cancer developed on average 83 months after the operation for gastric cancer. In the other 14 cases, gastric cancer developed on average 70 months after the operation for colorectal cancer. Therefore, careful pre-, intra-, or postoperative examinations are strongly called for in order to not overlook the presence of colorectal or gastric lesions in MPCGC cases.
我们调查了1972年至1996年间1277例结直肠癌患者中多原发性结直肠癌和胃癌（MPCGC）的发生情况。发现MPCGC患者65例（5.1%）。在28例同时性病例中，胃癌或结直肠癌是在术前、术中或术后检查时偶然发现的。在37例异时性病例中的23例中，结直肠癌平均在胃癌手术后83个月发生。在另外14例中，胃癌平均在结直肠癌手术后70个月发生。因此，强烈要求在术前、术中或术后进行仔细检查，以免在MPCGC病例中漏诊结直肠或胃部病变。
