Follow-up 71 patients during 20 months (12-29) operated on for colorectal cancer by laparoscopic or open surgery demonstrated no correlation between port-side metastases (1/35) or tumor recurrences (5/71) and intraperitoneal tumor cells. All these patients were cytologic-negative; however, all were initial in an advanced tumor stage (pT3-4, N1-3). We conclude from these results that free tumor cells during operation do not seem to influence outcome or the development of port-side metastases.
对71例接受腹腔镜或开放手术治疗的结直肠癌患者进行了20个月（12 - 29个月）的随访，结果显示端口侧转移（1/35）或肿瘤复发（5/71）与腹腔内肿瘤细胞之间无相关性。所有这些患者细胞学检查均为阴性；然而，所有患者最初均处于肿瘤晚期（pT3 - 4，N1 - 3）。从这些结果我们得出结论，手术期间游离的肿瘤细胞似乎不会影响预后或端口侧转移的发生。
