目的试图明确吸烟与大肠癌发生之间的关系。方法为回顾性分析病例对照研究,文中病例均来自我院2009-2011年的住院患者,将患者分为两组:大肠癌组计157例,肠道良性疾病组计80例。两组病例在年龄、性别方面匹配良好。分析两组病例中吸烟者所占比例,同时分析吸烟与性别、肿瘤发生部位之间是否存在联系。结果吸烟者(不论戒烟与否)在病例组中所占比率与对照组比较差异无统计学意义(P >0.05),在每日吸烟量、吸烟年限、吸烟指数等指标上,两组差异亦均无统计学意义(P >0.05)。吸烟者(不论戒烟与否)在不同部位的大肠癌患者中所占的比例差异无统计学意义(P >0.05),在每日吸烟量、吸烟年限、吸烟指数等指标上,不同部位肿瘤差异亦均无统计学意义(P >0.05)。结论吸烟并未增加罹患大肠癌的危险,但考虑到吸烟的其他危害,仍应远离烟草,及早戒烟。
Objective To clarify the relationship between smoking and the occurrence of colorectal cancer. Methods A retrospective analysis of case-control study, all cases were from our hospital from 2009 to 2011 inpatients, patients were divided into two groups: 157 cases of colorectal cancer group, 80 cases of intestinal benign disease group. Two groups of patients in age, gender, good match. Analyze the proportion of smokers in two groups of cases, and analyze whether there is a relationship between smoking and sex, tumor site. Results There was no significant difference in the proportion of smokers (whether smoking cessation or not) in the case group and the control group (P> 0.05). On the other hand, there was no significant difference in the daily smoking amount, smoking duration and smoking index No statistical significance (P> 0.05). The proportion of smokers (regardless of smoking cessation) in different parts of patients with colorectal cancer was no significant difference (P> 0.05), in the daily amount of smoking, smoking duration, smoking index and other indicators, different parts of the tumor Also no statistical significance (P> 0.05). Conclusions Smoking does not increase the risk of developing colorectal cancer, but taking into account other hazards of smoking, you should stay away from tobacco and stop smoking as soon as possible.
