General considerations, indications and contraindications for liver transplantation in Chile. A multicenter consensus development documentLiver transplantation is an excellent therapeutic option for terminal liver disease. During the last decades the results of liver transplantation have improved significantly with a patient survival rate of nearly 90% at one year and 80% at 5 years of follow-up. The main indications for liver transplantation include: end-stage liver disease associated to cirrhosis, acute liver failure, and hepatic tumors (mainly hepatocarcinoma). The absolute contraindications for a transplant are less frequent than in the past, and include: severe co-morbidity (cardiac or pulmonary), sepsis, advanced HIV disease and extra-hepatic malignancy. This document presents a Consensus of the main groups performing liver transplantation in Chile, about its indications and contraindications. It also reviews general aspects of liver transplantation, including the selection and referral of liver transplant candidates, allocation of organs and the evaluation of severity of liver disease (Rev Méd Chile 2008; 136: 793-804).

Post-transplant lymphoproliferative disorder (PTLD) is a major and potentially life-threatening complication after solid-organ transplantation. The aim of this study was to describe the disease characteristics, clinical practices, and survival related to PTLD in adult orthotopic liver transplant (OLT) recipients in South America. We conducted a survey at four different transplant groups from Argentina, Brazil, and Chile. Among 1621 OLT recipients, 27 developed PTLD (1.7%); the mean age at diagnosis was 53.7 (± 14) yr with a mean time of 39.7 (± 35.2) months from OLT to PTLD diagnosis. Initial therapy included reduction in immunosuppression alone in 23.1% of the patients. Either rituximab or chemotherapy was employed as initial or second-line therapy in 76.9% of the patients. PTLD location was frequently extranodal (80.7%) and mostly involving the transplanted liver (59.3%). The overall survival at one and five yr post-PTLD diagnosis was 53.8% and 46.2%, respectively. Significant univariate risk factors for post-PTLD mortality included lactate dehydrogenase ≥ 250 U/L (HR 9.66, p = 0.02), stage III/IV PTLD (HR 5.34, p = 0.004), and HCV infection (HR 7.68, p = 0.01). In conclusion, PTLD in OLT adult recipients is predominantly extranodal, and although mortality is high, long-term survival is possible.
