蜂窝式移动电话的使用与腮腺恶性肿瘤发病的相关性

Correlation between cellular phone use and risk of parotid gland malignancy

目的探讨蜂窝式移动电话的使用与腮腺恶性肿瘤发病的关系。方法采用病例对照研究,选择我院1993-2009年间收治的腮腺恶性肿瘤137例,按年龄性别匹配选择腮腺良性肿瘤403例作为对照组,通过问卷调查获得两组患者蜂窝式移动电话使用情况,应用Logistic回归分析,计算使用蜂窝式移动电话与发生腮腺恶性肿瘤间的关联强度OR值。结果使用蜂窝式移动电话患腮腺恶性肿瘤的风险是不用或使用时间半年以内者的1.503倍(OR95%CI:1.002-2.255),而累计通话时间达到181-594h及>594h者发病风险分别是2.122倍(OR95%CI:1.158-3.887)和1.795倍(OR95%CI:1.031-3.127)。结论使用蜂窝式移动电话累计通话时间过长患腮腺恶性肿瘤的风险增加。

Objective To study the correlation between cellular phone use and risk of parotid gland malignancy. Methods 947 eligible cases with parotid gland tumors admitted to our hospital from 1993 to 2009 were identified. 540 participants of them were interviewed, 137 malignancy cases of whom served as an experimental group, 403 benign cases of whom served as a control group. Their use of cellular phone was investigated using questionnaires. OR value for the correlation between cellular phone use and risk of parotid gland malignancy was calculated by Logistic regression analysis. Results The risk of developing parotid gland malignancy was 1.503-fold higher in patients who regularly used cellular phone than in those who did not use or used it for no more than 6 months（OR=1.503, 95% confidence interval CI=1.002-2.255）. The risk of developing parotid gland tumor was 2.122-fold and 1.795-fold higher respectively in patients who used cellular phone for 181-594h（OR=2.122, 95% CI=1.158-3.887） and over 594h（OR=1.795, 95% CI=1.031-3.127） than in those did not use or used it for no more than 6 months. Conclusion Over-long time of using cellular phone can raise the risk of parotid gland malignancy.
