Meta-analysis for the effect of hormone replacement therapy on survival rate in female with lung cancer.

OBJECTIVES:The effects of hormone replacement therapy on the survival rate of female lung cancer patients are still controversial. The Meta-analysis aims to systematically evaluate the effect of hormone replacement therapy on the survival rate of female lung cancer patients. METHODS:Retrospective studies regarding the effect of hormone replacement therapy on female lung cancer patients' survival rate were searched from the database of Embase, Cochrane, Pubmed, CNKI, Wanfang, and Weipu. The Meta-analysis was conducted with Stata 12.0 software. I2RESULTS:Five retrospective studies were included, involving 2 582 female patients with lung cancer. There were 1 054 cases of female lung cancer with hormone replacement therapy and 1 528 cases of female lung cancer without hormone replacement therapy. No publication bias was observed among these studies. The sensitivity analysis result showed that the overall results were stable. Meta-analysis showed that compared with patients without hormone replacement therapy, patients with hormone replacement therapy had an increased survival time for 5 years (ES=0.346; 95% CI 0.216 to 0.476; PCONCLUSIONS:Hormone replacement therapy improves 5-year survival in female lung cancer patients. Female lung cancer patients with menopausal syndrome can use hormone replacement therapy properly under their doctors' suggestion.
