作者将进展期直肠癌淋巴转移规律的研究结果应用于临床，施行了扩大淋巴结清除术。到１９８７年共治疗２１１例，并对术后随访超过５年的２００例的生存率与一般根治术进行了对比。结果表明，扩大根治术后的５、１０年生存率均显著高于一般根治术（前者分别为６８％及４７％，后者分别为４２．９％及２４．１％）。并对扩大根治术的手术要点、意义与适应证、并发症及预防等问题进行了讨论。
The authors applied the results of the study of lymphatic metastasis of advanced rectal cancer to the clinic and performed extensive lymphadenectomy. By 1987, a total of 211 cases had been treated, and the survival rate of 200 patients who had been followed up for more than 5 years had been compared with general radical surgery. The results showed that the 5-year and 10-year survival rates after radical mastectomy were significantly higher than those of conventional radical surgery (68% and 47% in the former and 42.9% in the latter and 24.1% in the latter). In addition, the key points, significance, indications, complications and prevention of extended radical mastectomy were discussed.
