Previous studies have suggested that patients with human immunodeficiency virus (HIV) infection are at higher risk of lung cancer, but the impact of HIV infection on the risk of mortality among lung cancer patients is still unclear. We conducted a systematic review and meta-analysis to clarify the association between HIV infection and mortality risk among lung cancer patients.
PubMed and Embase databases were searched to identify studies assessing the association between HIV infection and mortality risk among lung cancer patients. Only studies reporting adjusted relative risk (RR) of mortality among lung cancer patients with HIV infection were included. Meta-analysis of random-effect model was utilized to calculate the pooled RR with 95% confidence interval (CI).
Twelve cohort studies were finally included. Compared with lung cancer patients without HIV infection, the pooled RR of mortality among lung cancer patients with HIV infection was 1.48 (95% CI, 1.22-1.78, P < .001; I = 88.6%). After excluding 2 studies with low quality, HIV infection was still significantly associated with an elevated risk of mortality among lung cancer patients (RR = 1.51, 95% CI, 1.25-1.82, P < .001; I = 89.8%). Sensitivity analysis showed that the statistical significance of the pooled RR was not changed by excluding any one study.
The outcomes from the meta-analysis provide strong evidence for the elevated risk of mortality among lung cancer patients with HIV infection, and HIV infection is an important prognostic factor in lung cancer patients.
既往研究提示,人类免疫缺陷病毒(HIV)感染患者患肺癌的风险更高,但HIV感染对肺癌患者死亡风险的影响仍不明确。我们进行了一项系统评价和荟萃分析,以阐明HIV感染与肺癌患者死亡风险之间的关联。
检索PubMed和Embase数据库,以识别评估HIV感染与肺癌患者死亡风险之间关联的研究。仅纳入报告了HIV感染的肺癌患者死亡校正相对风险(RR)的研究。采用随机效应模型进行荟萃分析,计算合并RR及95%置信区间(CI)。
最终纳入12项队列研究。与未感染HIV的肺癌患者相比,感染HIV的肺癌患者死亡合并RR为1.48(95%CI,1.22 - 1.78,P<0.001;I=88.6%)。排除2项低质量研究后,HIV感染仍与肺癌患者死亡风险升高显著相关(RR=1.51,95%CI,1.25 - 1.82,P<0.001;I=89.8%)。敏感性分析表明,排除任何一项研究,合并RR的统计学意义均未改变。
荟萃分析结果为感染HIV的肺癌患者死亡风险升高提供了有力证据,HIV感染是肺癌患者的一个重要预后因素。
