“…However, it has also been shown through a retrospective analysis of the UNOS database that females have a 25% lower recurrence rate after transplant. Lastly, some literature suggested donor/recipient sex match may also play a role in HCC recurrence after LT[ 38 , 39 ]. Unfortunately we had limited data on tumor-specific variables in our study; for instance, we did not have tumor grade, AFP levels, or downstage data.…”

BACKGROUND Data examining the impact of sex on liver transplant (LT) outcomes are limited. It is clear that further research into sex-related differences in transplant patients is necessary to identify areas for improvement. Elucidation of these differences may help to identify specific areas of focus to improve on the organ matching process, as well as the peri- and post-operative care of these patients. AIM To utilize data from a high-volume Eurotransplant center to compare characteristics of male and female patients undergoing liver transplant and assess association between sex-specific variables with short- and long-term post-transplant outcomes. METHODS A retrospective review of the University of Essen’s transplant database was performed with collection of baseline patient characteristics, transplant-related data, and short-term outcomes. Comparisons of these data were made with Shapiro-Wilk, Mann-Whitney U , χ 2 and Bonferroni tests applied where appropriate. A P value of < 0.05 was accepted as statistically significant. RESULTS Of the total 779 LT recipients, 261 (33.5%) were female. Female patients suffered higher incidences of acute liver failure and lower incidences of alcohol-related or viremic liver disease (P = 0.001). Female patients were more likely to have received an organ from a female donor with a higher donor risk index score, and as a high urgency offer (all P < 0.05). Baseline characteristics of male and female recipients were also significantly different. In multivariate hazard regression analysis, recipient lab-Model for End-Stage Liver Disease score and donor cause of death were associated with long-term outcomes in females. Pre-operative diagnosis of hepatocellular carcinoma, age at time of listing, duration of surgery, and units transfused during surgery, were associated with long-term outcomes in males. Severity of complications was associated with long-term outcomes in both groups. Overall survival was similar in both males and females; however, when stratified by age, females < 50 years of age had the best survival. CONCLUSION Female and male LT recipients have different baseline and transplant-related characteristics, with sex-specific variables which are associated with long-term outcomes. Female recipients < 50 years of age demonstrated the best long-term outcomes. Pre- and post-transplant practices should be individualized based on sex-specific variables to optimize long-term outcomes.
