本文报告9例膀胱癌术后腹壁切口种植癌。原发膀胱癌为高分级、浸润性癌。种植癌亦皆为高分级癌,均位于腹直肌前鞘深面。5例合并复发性膀胱癌,3例有浅表淋巴结转移。文中对切口种植癌的发生、预后、预防和治疗进行了讨论。本文同时报告用电子显微镜观察噻替哌溶液浸泡离体膀胱癌细胞的结果,提示噻替哌有预防切口种植癌的作用。 This article reports 9 cases of bladder cancer after abdominal wall incision. Primary bladder cancer is a high grade, invasive cancer. Planting cancers are also high-grade cancers and are located deep in the rectus sheath. Five patients had recurrent bladder cancer and 3 had superficial lymph node metastases. This paper discusses the occurrence, prognosis, prevention and treatment of incision cancer. At the same time, the results of electron microscope observation of thiotepa solution soaking isolated bladder cancer cells have been reported, suggesting that thiotepa can prevent cancer in the incision.
