RESUMEN

BACKGROUND: Liver transplantation is a unique treatment opportunity for patients with chronic liver disease and hepatocellular carcinoma (HCC). Selection of HCC patients for transplantation was revolutionized by Milan-based criteria, but tumor recurrence and shortage of organs are still a major concern. Nowadays, additional preoperative tumor parameters can help to refine the graft allocation process. The objective of this study was to evaluate the prognostic value and cut-off points of pretransplant serum alpha-fetoprotein (AFP) levels and radiological tumor parameters on liver transplantation outcomes. METHODS: This is a single-team retrospective cohort of 162 consecutive deceased donor liver transplants (DDLT) with pathologically confirmed HCC. Pretransplant serum AFP levels and radiological tumor parameters were retrieved from a preoperative follow-up. Receiver-operating characteristics (ROC) curves were used to evaluate cut-off points for each outcome. Multivariate Cox regression model was used to assess the predictors of HCC relapse and recipient mortality. RESULTS: Twelve recipients (7.4%) had HCC recurrence after transplantation, with median survival time of 5.8 months. Pretransplant AFP ≥30 ng/mL (hazard ratio [HR]: 13.84, P = .003) and radiological total tumor diameter (TTD) ≥5 cm (HR: 12.89, P = .005) were independent predictors for HCC relapse. Moreover, pretransplant AFP ≥150 ng/mL was independently associated with recipient mortality (HR: 4.45, P = .003). CONCLUSIONS: Pretransplant AFP levels and radiological TTD were independently associated with HCC relapse and recipient mortality after DDLT, with different cut-off points predicting different outcomes. These findings may contribute to improving decision-making in the context of liver transplantation for HCC patients.

RESUMEN

INTRODUCTION: Liver transplantation is the standard treatment for end-stage liver disease. Brazil holds the third highest number of liver transplants performed per year, but center maldistribution results in high discrepancies in accessing this treatment. In 2012, an interstate partnership successfully implemented a new liver transplantation program in the middle west of Brazil. Here, we report the results of the first 500 liver transplants performed in this new program and discuss the impacts of a new transplant center in regional transplantation dynamics. METHODS: We reviewed data from the first 500 consecutive deceased donor liver transplants performed in the new program during an 8-year period. We analyzed data on patients' clinical and demographic profiles, postoperative outcomes, and graft and recipient survival rates. Univariate survival analysis was conducted using log-rank tests to compare the groups. RESULTS: Almost half (48%) of the procured organs and 40% of the recipients transplanted in our center were from outside our state. Recipient 30-day mortality was 9%. Overall recipient survival at 1 year and 5 years was 85% and 80%, respectively. Mortality was significantly associated with higher Model for End-Stage Liver Disease (P < .001) but not with the presence of hepatocellular carcinoma (P = .795). DISCUSSION: The new transplantation program treated patients from different regions of Brazil and became the reference center in liver transplantation for the middle west region. Despite the recent implementation, our outcomes are comparable to experienced centers around the world. This model can inspire the creation of new transplantation programs aiming to democratize access to liver transplantation nationwide.

RESUMEN

INTRODUCTION: In the era of shortage of organs for donation, transplantation from suboptimal donors is an expanding alternative to minimize waitlist mortality. In that sense, the safety of using organs from bacteremic donors has been a recurrent matter of discussion. We aimed to evaluate the influence of donor positive blood culture in the recipient and graft outcomes after liver transplantation from deceased donors. MATERIAL AND METHODS: Blood culture results from 255 deceased liver donors were retrospectively reviewed. Patients were categorized into 2 groups based on the recipients who obtained a graft from a donor with negative or positive blood culture. Graft and recipient outcomes were compared between the 2 groups using univariate survival analysis and multivariate regression models. Transmission of bloodstream infection from donor to recipient was assessed by reviewing recipients' microbiologic status when there was evidence of infection. RESULTS: Positive blood culture in donors was not associated with negative outcomes after transplantation. Death within 30 days after transplantation and overall recipient and graft survival did not differ between the 2 groups. Only Child-Pugh score ≥10 and retransplantation status were considered independent predictors of recipient death and graft failure. We identified 1 potential case of bacteremia transmission from donor to recipient. CONCLUSION: Donor positive blood culture was not associated with negative outcomes after liver transplantation. Transmission of infection from donor to recipient is possible, but rare. The results support the usage of bacteremic donors as a safe alternative to the scarcity of optimal donors.
