However, the conclusions regarding this issue are still conflicting. Hence, in this study, we performed a systematic review and meta-analysis to determine the prognostic significance of pretreatment serum albumin in BC patients. Materials and methods: A systematic search was carried out in PubMed, Embase, and Web of Science. A total of 16 studies involving 13,917 patients were included in the current meta-analysis. hazard ratios (HRs) and 95% CIs were pooled to assess the intensity of association. Moreover, heterogeneity, sensitivity analysis and publication bias were explored. All statistical analyses were conducted by STATA 12.0. Results: Our results suggested that a decreased pretreatment serum albumin level was closely related to a worse overall survival (HR 1.88, 95% CI 1.43, 2.48; P<0.01) and cancer-specific survival (HR 1.65, 95% CI 1.08, 2.52; P=0.02). In addition, from the results of this meta-analysis, it was also observed that a lower pretreatment serum albumin level was linked to higher incidence of postoperative 30-day complication (odds ratio [OR] 1.41, 95% CI 1.03, 1.91; P=0.03) and 90-day mortality (OR 2.51, 95% CI 1.82, 3.48; P<0.01). Furthermore, these findings were demonstrated to be reliable by our sensitivity and subgroup analysis stratified by ethnicity, analysis type, and cutoff value. Conclusion: Our results revealed that a lower pretreatment serum albumin level yields a poor long-term prognosis and increases the risks of postoperative complication and mortality in BC patients and can be applied to risk stratification and individualized therapy in BC patients.
