一般认为直肠癌的生物学行为较其它内脏器官为好,但其治疗效果还不令人满意。为提高其疗效,我院从1975年起对直肠癌的临床病理特征,淋巴转移规律,壁内逆向浸润,保留神经的功能性手术,术前放疗,术后化疗及抗癌药物代谢动力学等进行了系列研究,取得了良好的效果,现总结报告如下。 It is generally believed that the biological behavior of rectal cancer is better than other internal organs, but its therapeutic effect is still not satisfactory. In order to improve its curative effect, the clinical pathological features of rectal cancer, lymphatic metastasis, retrograde infiltration in the wall, functional surgery to preserve nerves, preoperative radiotherapy, postoperative chemotherapy and anticancer drug metabolism dynamics, etc. have been performed in our hospital since 1975. A series of studies was conducted and good results were obtained. The summary report is as follows.
