吸烟增加霍奇金淋巴瘤发病危险
2009/02/02
德国的研究报道,吸烟可以增加霍奇金淋巴瘤的发病危险,但与非霍奇金淋巴瘤的发病关系不大。
研究者在1992~2000年期间,共收集478590名参与调查者的吸烟信息,并对3567410人进行了为期一年的随访,评估吸烟对淋巴瘤发生和不同亚型的影响。
结果显示,有1371人确诊为淋巴瘤。吸烟使发生霍奇金淋巴瘤的相对危险度增加2倍以上(危险比为2.14),但对非霍奇金淋巴瘤的影响不大(危险比为1.06)。在这一前瞻性的研究中提示吸烟可以增加霍奇金淋巴瘤的发病风险。

Lymphomas are one of the few cancers that have been increasing in incidence over the past decades. So far, only a few established risk factors have been identified, including immunosuppression and viral infections. Recent evidence suggests etiologic heterogeneity of different lymphoma subtypes. Smoking may affect risk differently, depending on the lymphoma entity. The European Prospective Investigation into Cancer and Nutrition was used to study the role of smoking in the etiology of lymphomas and individual subtypes within a prospective study. Information on baseline and lifetime tobacco smoking by 478,590 participants was collected between 1992 and 2000. Cox proportional hazards regression was used to calculate multivariate-adjusted hazard ratios and 95% confidence intervals. During 3,567,410 person-years of follow-up, 1,371 lymphoma cases (1,304 non-Hodgkin’s lymphomas and 67 Hodgkin’s lymphomas) were identified. Relative risk for smokers at recruitment was more than twofold higher for Hodgkin’s lymphoma (hazard ratio = 2.14, 95% confidence interval: 1.18, 3.87) but was not elevated for non-Hodgkin’s lymphoma (hazard ratio = 1.06, 95% confidence interval: 0.94, 1.19) and individual B-cell non-Hodgkin’s lymphoma subtypes. In this prospective study, smoking appeared to increase Hodgkin’s lymphoma risk consistently in both genders, whereas B-cell non-Hodgkin’s lymphoma risk was not associated. Future analysis should involve viral biomarkers and genetic susceptibility markers to elucidate potential mechanisms of smoking-induced carcinogenesis, particularly for Hodgkin’s lymphoma.
