异时性多原发结肠癌合并原发性空肠腺癌1例

Metachronous multiple primary colon cancer with primary adenocarcinoma of the jejunum:a report of one case

异时性多原发结肠癌是在不同时间(相隔≥6mo)内在不同的部位相继出现结肠恶性肿瘤且病理排除同一种肿瘤复发及转移.本例患者在20年的时间内先后发生横结肠、升结肠、乙状结肠、降结肠及空肠腺癌,均行手术切除及术后全身化疗后疗效好,患者术后长期生存,临床上实属罕见.

Metachronous multiple primary colon cancer is defined as two or more newly developed cancers occurring at least 6 months after the initial colon cancer in different parts of the colon.Here,we reported a patient who developed primary colon cancers of the transverse colon,ascending colon,sigmoid colon and descending colon,and adenocarcinoma of the jejunum successively in 20 years.All cancers were subjected to surgical resection and postoperative chemotherapy.The patient had a good outcome and long-term postoperative survival,which is rarely seen in patients with such disease.
