Advances and improvements in cancer diagnosis and treatment have made it possible to find multiple primary cancers. We report here a rare case of metachronous quintuple cancer involving the stomach, rectum, colon, liver and prostate. An 80s‒ year‒old male was referred to our hospital with abnormality on upper GI series. He had undergone a distal gastrectomy in May 2005. Postoperative diagnosis was advanced gastric cancer (pT2N1M0, pStage ⅡA). In August 2006, anterior resection was performed with a diagnosis of advanced rectal cancer(pT3N0M0, pStage Ⅱa). For ascending colon polyps, endoscopic submucosal dissection was performed with a diagnosis of adenocarcinoma in adenoma(pTisN0M0, pStage 0)in September 2007. In June 2016, laparoscopic ileocecal resection was performed with a diagnosis of advanced cecum cancer(pT3N0M0, pStage Ⅱa). Follow up CT images showed a liver tumor in S4. Partial liver resection was performed in October 2010. Postoperative pathological diagnosis was hepatocellular carcinoma(pT2N0M0, pStage Ⅱ). Prostate cancer(cT2aN0M0)was treated by androgen deprivation therapy from February 2018. Although he had high‒frequency microsatellite instability, germline mutations in hMLH1 and hMSH2 genes were not detected. Histopathological examination showed that each tumor was an independent tumor and had not metastasized from any others. The patient had a good clinical course after these treatment until now.
