RESUMO

BACKGROUND: Prolonged time on the waiting list affects post-transplant survival of patients with hepatocellular carcinoma (HCC). However, it is not yet known which patients will be at higher risk for early dropout from the list. We investigate specific risk factors for early waiting list dropout in patients with HCC. METHODS: This was a single-center, intention-to-treat analysis of adults with HCC, within the Milan criteria, from July 2006 through September 2013. Patients were divided into groups according to waiting list time. The main end point was dropout from the list. RESULTS: The dropout rates of the study cohort at 3, 6, and 12-months were 6.4%, 12.4%, and 17.7%, respectively. Patients who dropped out from the list tended to be older, with blood types A and O, and with higher Child-Pugh and Model for End-Stage Liver Disease (MELD) scores. They also had larger nodules, responded poorly to trans-arterial chemo-embolization (TACE), and had a higher alpha-fetoprotein. Those with blood types B and AB appeared to be protected for dropout (odds ratio [OR] = 0.21, P = .02). Patients who responded to TACE were also protected (OR = 0.22, P < .001). When we looked into time to dropout, the only baseline characteristic that stood out was a higher MELD score (13 for those dropping out up to 90 days vs 10 for those dropping out after 180 days, P = .0025). CONCLUSIONS: We conclude that patients who drop out early from the list are primarily driven by the severity of liver disease. Patients who had progressive HCC had a high tumor load and poor response to loco-regional therapies, dropping out from the list after 180 days of inclusion.

RESUMO

INTRODUCTION: Since August 2010, The Brazilian National Transplantation System has allowed performance of liver transplantation (OLT) for patients with hepatocellular carcinoma (HCC) beyond the Milan criteria (MC) who have been successfully treated with preoperative downstaging (DS). Herein we sought to compare the clinical profiles and liver explant findings among patients with versus without preoperative DS. METHODOLOGY: Prospective cohort of patients with HCC within and beyond the MC undergoing OLT. Patients were considered for DS if they were beyond the MC without evidence of vascular invasion or extrahepatic disease. Transcatheter arterial chemoembolization was used for DS, which was considered to be successful if the MC were achieved at any moment during the follow-up. RESULTS: Between May 2006 and May 2010, we performed 130 OLTs in HCC patients, among whom 10 received preoperative DS. Both groups were comparable for gender, age, viral etiology, serum levels of alpha fetoprotein, and Child-Pugh and Model for End-Stage Liver Disease (MELD) scores (P > .05). The liver explants were within the MC in 80% of patients with preoperative DS and 90% of those without preoperative DS. They were comparable for the number of HCC nodules, total tumor size, histologic grade, and presence of microvascular invasion. Patients with pretransplant DS showed larger HCC nodules (33.3 ± 9.65 vs 26.3 ± 9.62 mm; P .029) and more frequent macrovascular invasion (1 vs 1 patient, P = .024). CONCLUSION: Preoperative DS for unresectable HCC may provide a curative treatment for patients who would otherwise be candidates for palliative therapy only. The baseline characteristics and liver explant findings were similar in both groups. We have yet to determine whether the differences observed regarding the size of the largest nodule and the higher frequency of macrovascular invasion have an impact on outcome.

RESUMO

INTRODUCTION: Orthotopic liver transplantation (OLT) is an excellent option for patients with unresectable hepatocellular carcinoma (HCC) within the Milan criteria. Recurrence of HCC has a severe impact on post-OLT survival. In this study, we performed an analysis of post-OLT recurrence pattern of HCC. METHODS: The prospective cohort of OLT patients included those with unresectable HCC within the Milan criteria, and those beyond the Milan criteria who were downstaged with transcatheter arterial embolization until they achieved the Milan criteria. RESULTS: Between May 2006 and May 2011, we performed 130 OLT for unresectable HCC within the Milan Criteria among whom 9 patients (6.9%) experienced tumor recurrence. Two (22.2%) had undergone preoperative downstaging. At the time of OLT, mean serum alpha-fetoprotein levels were 623.8 ± 682.9 ng/mL. The liver explants showed 7 (77.8%) subjects were within the Milan criteria, with an average 2.6 ± 2.2 tumors, most of which (89%) were moderately differentiated. Microvascular and macrovascular invasion were observed in 5 (55.6%) and 2 (22.2%) cases, respectively. Liver explants were beyond the Milan criteria in both patients who had undergone preoperative downstaging. Recurrence occurred 23.1 ± 14.3 months after OLT, having been detected in the liver (n = 3; 33.3%), lung (n = 3; 33.3%), brain, peritoneum, and adrenal gland (n = 1 each; 11.1% each). Mean survival after detection of recurrence was 137.4 ± 96.4 days. CONCLUSIONS: Despite strict candidate selection criteria, HCC recurrence may occur after OLT, bearing a significant impact on posttransplant outcomes to optimize results requires refinements in candidate selection, as well as well-defined cost-effective post-OLT surveillance protocols.

RESUMO

Hepatitis B (HBV) is a public health problem worldwide; one-third of the population has already been in contact with HBV, and 350 million people are chronic carriers of virus. The appearance of hyperimmune gamma globulin and antiviral drugs has allowed that group to undergone hepatic transplantation, achieving satisfactory results to prevent a relapse. But the use of hyperimmune gamma globulin has an extremely high cost, and combined therapies with new antiviral drugs seem to be a therapeutic alternative. We analyzed 21 patients with hepatitis B associated or not with Delta hepatitis over a mean follow-up period of 19.5 months, concluding that use of only nucleotide analogues has sufficient to achieve satisfactory results.

RESUMO

The solid and cystic tumour of the pancreas is a rare entity that occurs in young women. Clinically the patients are often asymptomatic, the tumor of variable size (2-10 cm) and show a fibrous encapsulation. In contrast to adenocarcinoma of pancreatic ductal cells, which is the most frequent tumor of the pancreas, this tumour have a slow growth, usually do not have metastases and have a favourable prognosis. The authors related the case and have done a revision of the illness.
