Hepatocellular carcinoma in patients coinfected with hepatitis B or C and HIV: more aggressive tumor behavior?

INTRODUCTION AND OBJECTIVES: Hepatocellular carcinoma (HCC) is the 6th cause of cancer and hepatitis C (HCV) and B (HBV) viruses are the most frequent risk factors for HCC. Patients coinfected with HCV or HBV and HIV present a faster progression to liver fibrosis and higher incidence of HCC. The aim of this study was to evaluate the survival and clinical outcomes of coinfected patients with HCC comparing with non-HIV patients. METHODS: We conducted a retrospective cohort study, including 267 HCC patients with HCV or HBV infection with or without HIV. The primary endpoint was overall survival. A Kaplan-Meier curve was presented to assess survival function. Clinical and radiologic variables, according to HIV status, were compared by logistic regression. RESULTS: Among 267 HCC patients, 25 (9.3%) were HIV-positive. In the coinfected group, patients were younger (49.8 vs 61.2 years, P < 0.001), cirrhosis was less predominant (88 vs 96.7%, P = 0.05), a smaller proportion received HCC treatment (60 vs 86.3%, P = 0.001) and the frequency of portal vein tumoral thrombosis was higher (32 vs 11.1%, P = 0.003). The overall mortality rate was higher in the HIV-positive group (92 vs 74.3%), independently of clinical and tumoral variables. CONCLUSION: Coinfected patients with HCC presented higher mortality, tumor diagnosis in a younger age, less underlying cirrhosis and a higher frequency of tumoral thrombosis. Further studies are warranted to better understand the role of HIV in hepatocarcinogenesis, in order to improve the management of those patients, particularly regarding screening programs.

Management of Hepatocellular Carcinoma during the COVID-19 Pandemic - São Paulo Clínicas Liver Cancer Group Multidisciplinary Consensus Statement.

More than 18 million people in 188 countries have been diagnosed as having coronavirus disease (COVID-19), and COVID-19 has been responsible for more than 600,000 deaths worldwide. Brazil is now the second most affected country globally. Faced with this scenario, various public health measures and changes in the daily routines of hospitals were implemented to stop the pandemic. Patients with hepatocellular carcinoma (HCC) are at an increased risk for severe COVID-19 as they present with two major diseases: cancer and concomitant chronic liver disease. The COVID-19 pandemic can significantly impact the management of HCC patients from diagnosis to treatment strategies. These patients need special attention and assistance at this time, especially since treatment for tumors cannot be delayed in most cases. The aim of this guideline was to standardize the management of HCC patients during the COVID-19 pandemic. This document was developed, on the basis of the best evidence available, by a multidisciplinary team from Instituto do Câncer do Estado de São Paulo (ICESP), and Instituto Central of the Hospital das Clínicas da Universidade de São Paulo (HC-FMUSP), which are members of the São Paulo Clínicas Liver Cancer Group.

Adherence to BCLC recommendations for the treatment of hepatocellular carcinoma: impact on survival according to stage.

OBJECTIVES:: This study sought to assess the adherence of newly diagnosed hepatocellular carcinoma patients to the Barcelona Clinic Liver Cancer system treatment guidelines and to examine the impact of adherence on the survival of patients in different stages of the disease. METHODS:: This study included all patients referred for the treatment of hepatocellular carcinoma between 2010 and 2012. Patients (n=364) were classified according to the Barcelona Clinic Liver Cancer guidelines. Deviations from the recommended guidelines were discussed, and treatment was determined by a multidisciplinary team. The overall survival curves were estimated with the Kaplan-Meier method and were compared using the log-rank test. RESULTS:: The overall rate of adherence to the guidelines was 52%. The rate of adherence of patients in each scoring group varied as follows: stage 0, 33%; stage A, 45%; stage B, 78%; stage C, 35%; and stage D, 67%. In stage 0/A, adherent patients had a significantly better overall survival than non-adherent patients (hazard ratio=0.19, 95% confidence interval (CI): 0.09-0.42; p<0.001). Among the stage D patients, the overall survival rate was worse in adherent patients than in non-adherent patients (hazard ratio=4.0, 95% CI: 1.67-9.88; p<0.001), whereas no differences were observed in patients in stages B or C. CONCLUSIONS:: The rate of adherence to the Barcelona Clinic Liver Cancer staging system in clinical practice varies according to clinical disease stage. Adherence to the recommended guidelines positively impacts survival, especially in patients with early-stage disease.

Hepatocellular Carcinoma Management in Nonalcoholic Fatty Liver Disease Patients: Applicability of the BCLC Staging System.

BACKGROUND/AIMS: Nonalcoholic fatty liver disease (NAFLD) has emerged as an important cause of chronic liver disease, cirrhosis, and hepatocellular carcinoma (HCC). The Barcelona Clinic Liver Cancer (BCLC) system is the preferred staging system to evaluate patients with HCC and links prognosis assessment with treatment recommendation. The aim of this retrospective study was to evaluate whether the BCLC staging system and its treatment algorithm are suitable for patients with HCC arising from NAFLD. METHODS: Forty-two patients with HCC related to either to NAFLD or cryptogenic cirrhosis were retrieved retrospectively from 2 centers in Brazil. Patients were classified according to BCLC staging system. If the proposed HCC therapy could not be applied, the case was considered to represent deviations from the recommended BCLC guideline. Causes of treatment deviations were investigated. RESULTS: There were 4 patients without evidence of cirrhosis according to liver biopsy and/or clinical evaluation. One (2%), 21 (50%), 10 (24%), 5 (12%), and 5 patients (12%) were classified initially to the very early (0), early (A), intermediate (B), advanced (C), and terminal (D) BCLC stages, respectively. Thirty-five patients (83%) were treated according to BCLC recommendations. There were 3 cases (of 5) of protocol deviation in BCLC C patients. The 1- and 2-year overall survival rates were 81% and 66%, respectively. CONCLUSIONS: The BCLC system is applied in most cases of NAFLD-related HCC cases. Deviation of BCLC is found more frequently in BCLC C stage patients.

Clinical and pathological evaluation of fibrolamellar hepatocellular carcinoma: a single center study of 21 cases.

OBJECTIVES: Fibrolamellar hepatocellular carcinoma is a rare primary malignant liver tumor that differs from conventional hepatocellular carcinoma in several aspects. The aim of this study was to describe the clinical, surgical and histopathological features of fibrolamellar hepatocellular carcinoma and to analyze the factors associated with survival. METHODS: We identified 21 patients with histopathologically diagnosed fibrolamellar hepatocellular carcinoma over a 22-year period. Clinical information was collected from medical records and biopsies, and surgical specimens were reviewed. RESULTS: The median age at diagnosis was 20 years. Most patients were female (67%) and did not have associated chronic liver disease. Most patients had a single nodule, and the median tumor size was 120 mm. Vascular invasion was present in 31% of patients, and extra-hepatic metastases were present in 53%. Fourteen patients underwent surgery as the first-line therapy, three received chemotherapy, and four received palliative care. Eighteen patients had "pure fibrolamellar hepatocellular carcinoma," whereas three had a distinct area of conventional hepatocellular carcinoma and were classified as having "mixed fibrolamellar hepatocellular carcinoma." The median overall survival was 36 months. The presence of "mixed fibrolamellar hepatocellular carcinoma" and macrovascular invasion were predictors of poor survival. Vascular invasion was associated with an increased risk of recurrence in patients who underwent surgery. CONCLUSION: Fibrolamellar hepatocellular carcinoma was more common in young female patients without chronic liver disease. Surgery was the first therapeutic option to achieve disease control, even in advanced cases. Vascular invasion was a risk factor for tumor recurrence. The presence of macrovascular invasion and areas of conventional hepatocellular carcinoma were directly related to poor survival.
