ABSTRACT

Preoperative chemotherapy followed by surgery was applied in three patients, aged 68 years (male), 48 years (female), and 80 years (male) with locally advanced cancer of the colon with bladder invasion. Achieving a resection with free margins (R0) is essential in colon-cancer surgery, but the role of preoperative chemotherapy in colon cancer remains unknown. When a tumour is presumed to be unresectable, guidelines recommend discussing the case and possibly referring the patient to an oncological


expertise centre, where each patient will be individually assessed for the most suitable preoperative treatment and surgery during a multidisciplinary tumour board meeting. All three patients showed that preoperative chemotherapy led to down-staging and reduction of the tumour size, although removal of the bladder was still necessary in one patient. All patients underwent a complete resection, which resulted in long-term disease-free and overall survival.
