据美国癌症协会估计,1977年美国有101,000结直肠癌新发病例,占癌症发病率之首位,51,300人死于本病,其死亡率仅次于肺癌。在治疗方面,“根治性切除术”总的生存率有所提高,但术后复发率仍较高,远期疗效尚不令人满意。为了提高疗效,近年来除进一步改进手术技术外,还在放疗、化疗、免疫、电凝和冷冻等综合治疗方面做了一些努力,现分述如下。 According to the American Cancer Society’s estimate, in the United States, there were 101,000 new cases of colorectal cancer in the United States in 1977, accounting for the highest incidence of cancer, 51,300 people died of the disease, and the mortality rate was second only to lung cancer. In terms of treatment, the overall survival rate of “radical resection” has increased, but the recurrence rate is still high, and the long-term effect is not satisfactory. In order to improve the efficacy, in addition to further improvement of surgical techniques in recent years, some efforts have been made in radiotherapy, chemotherapy, immunity, electrocoagulation, and freezing and other comprehensive treatment, and are now described as follows.
