Survival from biliary tract cancer and increased body weight: a systematic review and meta-analysis
Summary:
The role of overweight and obesity on the prognosis of biliary tract cancer (BTC) remains unclear. This systematic review and meta-analysis aims to examine the association between being overweight/obesity and BTC prognosis (overall survival, progression-free survival and response rates). Potentially eligible publications were sought in PubMed up to December 31, 2019. Random-effects meta-analysis was conducted to combine estimates; Cochran Q and I2 statistic and were used for the assessment of between-study heterogeneity. Five observational studies including a total of 1,160 tumor patients were included in the qualitative synthesis, among which three studies were retained for the meta-analysis, involving 1,060 cancer cases. No statistically significant association was found between overweight/obesity and the overall survival of BTC [pooled hazard ratios (HR)=1.07; 95% confidence interval (95% CI): 0.85-1.35, seven study arms]. Notably, in a subgroup analysis, obese subjects showed decreased overall survival [pooled HR=1.57; 95% CI: 1.03-2.40, two study arms] versus normal weight patients. In conclusion, there is suggestive evidence that obesity may contribute to poorer prognosis of biliary cancer, in comparison to normal weight status. Additional studies from various geographic regions are needed to further substantiate and validate the present findings.
