医药学论文:多因素回归分析中医药干预对大肠癌预后的影响
【摘要】 目的 应用多因素分析的方法探讨中医药治疗对大肠癌预后的影响。方法 应用COX-多因素回归分析,对200余例大肠癌病例的临床资料进行回顾性分析,主要分析中医药干预因素对预后的影响。结果 大肠癌患者的发病年龄、中医药切入时间、中医药作用时间以及放射治疗等四个因素与术后发生复发、转移显著相关(P< 0.05);中医药干预是影响发生复发、转移后大肠癌患者生存时间的独立因素(P< 0.01)。结论 大肠癌患者较早开始中医药治疗可以改善其预后;中医药治疗在晚期大肠癌的治疗性干预中具有显著的优势作用。

Multi-variable regression analysis of prognosis of colorectal cancer treated by traditional Chinese medicine
【Abstract】 Objective The Cox multi-variable regression analysis was used to evaluate the relationship between prognosis of colorectal cancer and the TCM(traditional Chinese medicine) treatment. Methods The clinic-correlative factors or variables of 200 patients with colorectal cancer were analyzed by Log-Rank test and by Cox proportional hazards model.Results Patient's age, the time the TCM intervening in, the course of the TCM, and radiotherapy influenced the rate of local-recurrence and remote-metastasis(terminal events) occurring by single variable analysis (P< 0.05). The factors of age and the TCM intervening time were related with terminal events after surgical treatment by multivariable analysis (P< 0.05). The factor of the TCM treatment was significant correlated with survival time of patients with terminal events (P< 0.01).Conclusion Earlier intervening in of the TCM has a good influence on the prognosis of colorectal cancer. The TCM treatment brings the most great advantage to the post- metastasis-or remote-patients in their terminal periods than any other treatments did.

COX-多因素回归分析可以在诸多相关变量中筛选并检验一个、或多个与事件结果显著相关的因素。本文对200余例大肠癌病例的临床资料进行多因素分析,探讨中医药治疗对大肠癌预后的影响。
1 资料与方法
1.1 一般资料 在1998年1月1日~2004年3月31日就诊的大肠癌病例中获得201例可进行统计的病例资料。其中结肠癌92例,直肠癌109例。男102例,女99例。所有病例均有明确病理学诊断依据,均为腺癌。行根治术170例,姑息术20例,11例未行手术治疗。确诊时已发生转移者30例,根治术后170例中有51例(30.0%)发生转移或复发(晚期事件),共81例;其中肝转移39例(76.5%),腹盆腔转移19例(37.3%),肺转移12例(23.5%),淋巴结转移6例(11.8%),有术后复发16例(31.4%)。170例根治术后病例中155例(91.2%)接受了中医药治疗,发生转移或复发的81例有中58例(71.6%)接受了中医药治疗。
