Abstract

Colonic metastasis from ovarian cancer is extremely rare, with only seven reported cases. A 77-year-old woman who had previously undergone surgery for ovarian cancer was admitted to a local hospital with anal bleeding. Histopathological analysis confirmed the presence of adenocarcinoma. Colonoscopy revealed a descending colon tumor. The patient was diagnosed with Union for International Cancer Control T3N0M0 descending colon cancer or colon metastasis of the ovarian cancer. Laparoscopic left colectomy was performed; intraoperative frozen section diagnosis confirmed metastasis from ovarian cancer, and the absence of invasion to the serosal surface suggested hematogenous metastasis. This is the first case of colonic metastasis from ovarian cancer that was diagnosed using an intraoperative frozen section and laparoscopically treated.

卵巢癌向降结肠的转移。

卵巢癌的结肠转移极为罕见，仅报道了7例。一名77岁的妇女曾接受过卵巢癌手术，因肛门出血住进当地一家医院。组织病理学分析证实了腺癌的存在。结肠镜检查发现一降结肠肿瘤。患者被诊断为国际癌症控制联盟T3N0M0降结肠癌或卵巢癌结肠转移。行腹腔镜左结肠切除术;术中冰冻切片诊断证实卵巢癌转移，浆膜表面未见浸润提示血行转移。这是第一例使用术中冷冻切片诊断和腹腔镜治疗的卵巢癌结肠转移病例。
