背景:吸烟与皮肤光损伤或恶性肿瘤之间的关系尚不清楚。除了吸烟,紫外线辐射和免疫抑制对致癌作用都有影响。目的是研究吸烟与皮肤光老化的关系,光化性角化病(AK),皮肤癌,和色素细胞痣的成年受试者有任何类型的皮肤癌的风险。
方法:在库奥皮奥大学医院的这项横断面研究中,芬兰,2017年5月至2020年10月,488名受试者(年龄21-79岁,246名男性和242名女性,94例免疫抑制)检查了各种皮肤病变,光老化严重程度,Nevi,烟草包装年(TPY),以及可能的混杂因素。
结果:在逻辑回归分析中,在TPY和皮肤总光老化之间没有发现明显的关联,面部光老化,AK,或者痣,特别是当其他混杂因素,比如年龄,被考虑。此外,TPY与黑色素瘤无关,基底细胞癌,或任何类型的皮肤癌。然而,与不吸烟者相比,曾经吸烟者的鳞状细胞癌(SCC)的粗比值比升高(OR=1.99;95%CI:1.02-3.88,p=0.043).在进一步分析中,≤10的TPY产生SCC的多变量调整比值比升高(AOR=4.90;95%CI:1.31-18.26,p=0.018),但TPY>10没有(AOR=1.14;95%CI:0.22-6.05,p=0.876)。
结论:吸烟与虽然不是剂量依赖性的,随着SCC可能性的增加,但与基底细胞癌或黑色素瘤无关.然而,吸烟对皮肤光老化严重程度的影响,AK,还有Nevi,似乎很虚弱。
BACKGROUND: The relationship between tobacco smoking and cutaneous photodamage or malignancies is still unclear. In addition to smoking, both ultraviolet radiation and immunosuppression have an impact on carcinogenesis. The purpose was to
study the association of smoking with cutaneous photoaging, actinic keratosis (AK), skin cancers, and pigment cell nevi in adult subjects at risk of any type of skin cancer.
METHODS: In this cross-sectional
study at Kuopio University Hospital, Finland, between May 2017 and October 2020, 488 subjects (aged 21-79 years, 246 males and 242 females, 94 with immunosuppression) were examined for a variety of skin lesions, photoaging severity, nevi, tobacco pack-years (TPY), as well as for possible confounding factors.
RESULTS: In logistic regression analyses, no marked association was found between TPY and total skin photoaging, facial photoaging, AK, or nevi, especially when other confounding factors, such as age, were considered. In addition, TPY was not associated with melanoma, basal cell carcinoma, or any type of skin cancer. However, ever smokers produced an elevated crude odds ratio (OR=1.99; 95% CI: 1.02-3.88, p=0.043) for squamous cell carcinoma (SCC) compared to non-smokers. In further analysis, TPY of ≤10 produced an elevated multivariable adjusted odds ratio (AOR=4.90; 95% CI: 1.31-18.26, p=0.018) for SCC, but TPY >10 did not (AOR=1.14; 95% CI: 0.22-6.05, p=0.876).
CONCLUSIONS: Smoking was associated, though not dose-dependently, with an increased likelihood of SCC, but it was not associated with basal cell carcinoma or melanoma. However, the impact of smoking on cutaneous photoaging severity, AK, and nevi, appears to be weak.
