随道国内外结、直肠癌发病率不断上升的趋势,尽管在治疗上已取得了很大进展,但术后平均5年生存率仍低于40%~50%,治愈性癌肿切除术后的平均复发率约为30%。局部复发和转移是影响患者生存率的主要原因。因此结、直肠肿瘤复发再手术越来越受到重视。本文就1990年2月至1995年11月间20例复发性结、直肠癌再手术者,分析其复发的原因,认为复发与病理分期、淋巴结转移情况、病理类型、肿瘤分化程度、生长部位、首次手术情况等有密切关系,阐述了复发性结、直肠癌的外科处理方法,以期减少复发,提高生存率。
With the increasing incidence of colorectal cancer and rectal cancer at home and abroad, despite significant advances in treatment, the average 5-year survival rate after surgery is still below 40% to 50%, after curative cancer resection. The average recurrence rate is about 30%. Local recurrence and metastasis are the main reasons that affect the survival rate of patients. Therefore, rectal tumor recurrence and reoperation are getting more and more attention. This article analyzes the causes of recurrence in 20 patients with recurrent colorectal cancer and rectal cancer from February 1990 to November 1995. The recurrence and pathological stage, lymph node metastasis, pathological type, tumor differentiation, and growth site are considered. The first surgical situation is closely related to the surgical treatment of recurrent knots and rectal cancers in order to reduce recurrence and improve survival.
