Abstract

Background: The role of smoking in the prognosis of bladder cancer may significantly impact clinical management. It is also a considerable burden to Taiwan's economy and health of its citizens.

Objective: To search Taiwan's National Health Insurance Research Database to determine whether smoking affected overall and cancer-specific mortality of patients with bladder cancer.

Methods: We collected data on basic information, tumor stage, and comorbidities. Each smoking case was propensity score-matched by age, sex, and diagnosis year to one control individual among bladder cancer patients. The study comprised a never-smoke and an ever-smoke group, with each group including 4,728 patients after matching. We evaluated the association between smoking and mortalities in patients with bladder cancer. Cox proportional regression modeling was used to estimate hazard ratios (HRs) of overall and cancer-specific mortality rates. Stratified analysis was also performed to estimate risk ratios of overall and cancer-specific mortalities in bladder cancer patients with and without a history of smoking history among different subgroups.

Results: The overall and specific mortality ratio of patients who were ever smokers were 1.15-fold and 1.16-fold, respectively, compared with those of never smokers (overall: 95% confidence interval [CI], 1.06-1.26, P = 0.0014; specific: 95% CI, 1.03-1. 03, P = 0.0176). Patients with bladder cancer who smoked and had significantly higher overall and specific mortality rates were those with Charlson Comorbidity Index (CCI)≥3 (overall: P = 0.0119; specific: P = 0.0092), diabetes mellitus (DM; overall: P = 0.0046; specific: P = 0.0419), and non-muscle-invasive bladder cancer (NMIBC; overall: P = 0.0038; specific: P = 0.0014).

Conclusions: Overall and specific mortality rates were significantly higher in the ever-smoke group than in the never-smoke group. The ever-smoke group with male sex, CCI≥3, DM, and NMIBC had increased risks for overall and specific mortality.

吸烟与膀胱癌患者总体和特定死亡率之间的关系:一项基于人群的研究

背景:吸烟在膀胱癌预后中的作用可能会显著影响临床治疗。这对台湾的经济和公民的健康也是相当大的负担。目的:检索台湾全民健康保险研究数据库，以确定吸烟是否影响膀胱癌患者的总体死亡率和癌症特异性死亡率。方法:我们收集基本信息、肿瘤分期和合并症的资料。在膀胱癌患者中，每个吸烟病例按年龄、性别和诊断年份与一个对照个体进行倾向评分匹配。该研究分为从不吸烟组和经常吸烟组，每组匹配后包括4,728名患者。我们评估了膀胱癌患者吸烟与死亡率之间的关系。Cox比例回归模型用于估计总体死亡率和癌症特异性死亡率的风险比(hr)。还进行了分层分析，以估计不同亚组中有和没有吸烟史的膀胱癌患者的总体死亡率和癌症特异性死亡率的风险比。结果:与不吸烟者相比，曾经吸烟患者的总死亡率和特定死亡率分别为1.15倍和1.16倍(总体:95%可信区间[CI]， 1.06-1.26, P = 0.0014;特异性:95% CI, 1.03-1。03, p = 0.0176)。吸烟的膀胱癌患者总体死亡率和特定死亡率均显著高于Charlson合并症指数(CCI)≥3的患者(总体:P = 0.0119;特异性:P = 0.0092)，糖尿病(DM;总体:P = 0.0046;特异性:P = 0.0419)，非肌肉浸润性膀胱癌(NMIBC;总体:P = 0.0038;特异性:P = 0.0014)。结论:吸烟组的总死亡率和特定死亡率显著高于不吸烟组。经常吸烟的男性、CCI≥3、糖尿病和NMIBC组的总死亡率和特异性死亡率风险增加。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
