abstract
PURPOSE: The incidence of breast cancer following solid organ transplantation is comparable to the age-matched general population. The rate of de novo breast cancer following liver transplantation varies. Furthermore, there is limited information on the management and outcomes of breast cancer in liver transplant recipients. We aim to evaluate the impact of liver transplantation on breast cancer surgery outcomes and compare the outcomes after breast cancer surgery in liver transplant recipient in transplant versus non-transplant centers. METHODS: National Inpatient Sample database was accessed to identify liver transplant recipient with breast cancer. Mortality, complications, hospital charges, and total length of stay were evaluated with multivariate logistic regression testing. Weighted multivariate regression models were employed to compare outcomes at transplant and non-transplant centers. RESULTS: Ninety-nine women met inclusion criteria for liver transplantation + breast cancer and were compared against women with breast cancer without liver transplantation (n = 736,527). Liver transplantation + breast cancer had lower performance status as confirmed via higher Elixhauser Comorbidity Index (20.5% vs 10.2%, p < 0001). There were significantly more complications in the liver transplantation cohort when compared to the non-liver transplant recipient (15.0% vs 8.2%, p = 0.012). However, on multivariate analysis, liver transplantation was not an independent risk factor for post-operative complications following breast cancer surgery (odd ratio, 1.223, p = 0.480). Cost associated with breast cancer care was significantly higher in those with liver transplantation (2.621, p < 0.001). Breast conservation surgery in liver transplantation had shorter length of stay as compared to breast cancer alone (odds ratio, 0.568, p = 0.027) in all hospitals. CONCLUSION: Liver transplantation does not increase short-term mortality when undergoing breast cancer surgery. Although there were significantly more complications in the liver transplantation cohort when compared to the non-liver transplant recipient (15.0% vs 8.2%, p = 0.012), on multivariate analysis, liver transplantation was not an independent risk factor for postoperative complications following breast cancer surgery. Breast cancer management in liver transplant recipient at non-transplant centers incurred higher charges but no difference in complication rate or length of stay when compared to transplant centers.
