- Interferon lambda and hepatitis C virus core protein polymorphisms associated with liver cancer(2016) MOREIRA, Joao Paulo; MALTA, Fernanda de Mello; DINIZ, Marcio Augusto; KIKUCHI, Luciana; CHAGAS, Aline Lopes; LIMA, Livia de Souza Botelho; GOMES-GOUVEA, Michele Soares; CASTRO, Vanessa Fusco Duarte de; SANTANA, Rubia Anita Ferraz; SUMITA, Nairo Massakazu; VEZOZZO, Denise Cerqueira Paranagua; CARRILHO, Flair Jose; PINHO, Joao Renato RebelloBackground: Hepatitis C virus (HCV) infection is often persistent and gradually advances from chronic hepatitis to liver cirrhosis and hepatocellular carcinoma (HCC). Worldwide, hepatocellular carcinoma is the fifth most common neoplasm. Method of study: the Interferon lambda (IFNL) polymorphisms genotypes (rs8099917, rs12979860 and rs12980275) and the presence of mutations in HCV core protein were analyzed in 59 patients with HCC, and also in 50 cirrhotic patients (without HCC). Results: the rs12980275-AG genotype was associated with HCC on age-adjusted analysis (OR 2.42, 95% CI 1.03-5.69, P=0.043). Core substitutions R70Q and L91M were mainly found in genotype 1b isolates. Furthermore, a borderline level of statistical significance association was found among the presence of amino acid Glutamine (Q) in the position 70 and IFNL3 genotype AG (P=0.054). Conclusions: the screening of these polymorphisms and functional studies would be useful in clinical practice for identifying groups at high risk of HCC development.
- Hepatocellular Carcinoma Management in Nonalcoholic Fatty Liver Disease Patients Applicability of the BCLC Staging System(2016) KIKUCHI, Luciana; OLIVEIRA, Claudia P.; ALVARES-DA-SILVA, Mario R.; TANI, Claudia M.; DINIZ, Marcio A.; STEFANO, Jose T.; CHAGAS, Aline L.; ALENCAR, Regiane S. S. M.; VEZOZZO, Denise C. P.; SANTOS, Gilmar R.; CAMPOS, Priscila B.; ALVES, Venancio A. F.; RATZIU, Vlad; CARRILHO, Flair J.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.
- Brazilian society of hepatology recommendations for the diagnosis and treatment of hepatocellular carcinoma(2015) CARRILHO, Flair J; MATTOS, Angelo Alves de; VIANEY, Alex F; VEZOZZO, Denise Cerqueira P; MARINHO, Fábio; SOUTO, Francisco J; COTRIM, Helma P; COELHO, Henrique Sergio M; SILVA, Ivonete; GARCIA, José Huygens P; KIKUCHI, Luciana; LOFEGO, Patricia; ANDRAUS, Wellington; STRAUSS, Edna; SILVA, Giovanni; ALTIKES, Isaac; MEDEIROS, Jose Eymard; BITTENCOURT, Paulo L; PARISE, Edison RABSTRACT Hepatocellular carcinoma is a malignancy of global importance and is associated with a high rate of mortality. Recent advances in the diagnosis and treatment of this disease make it imperative to update the recommendations on the management of the disease. In order to draw evidence-based recommendations concering the diagnosis and management of hepatocellular carcinoma, the Brazilian Society of Hepatology has sponsored a single-topic meeting in João Pessoa (PB). All the invited pannelists were asked to make a systematic review of the literature and to present topics related to the risk factors for its development, methods of screening, radiological diagnosis, staging systems, curative and palliative treatments and hepatocellular carcinoma in noncirrhotic liver. After the meeting, all panelists gathered together for the discussion of the topics and the elaboration of those recommendations. The text was subsequently submitted for suggestions and approval of all members of the Brazilian Society of Hepatology through its homepage. The present paper is the final version of the reviewed manuscript containing the recommendations of the Brazilian Society of Hepatology.
- Clinical and epidemiological aspects of hepatocellular carcinoma in Brazil(2013) KIKUCHI, Luciana; CHAGAS, Aline L.; ALENCAR, Regiane S. S. M.; PARANAGUA-VEZOZZO, Denise C.; CARRILHO, Flair J.The global hepatocellular carcinoma (HCC) incidence is widely variable, depending on geographic region and the prevalence of major risk factors. In Brazil, two large multicentre retrospective studies were performed to investigate clinical and epidemiological aspects of HCC. In the first study, performed in 1997, HCC was found in cirrhotic livers in 71% of cases. Chronic alcoholism was present in 36% of cases, chronic hepatitis B in 35% and hepatitis C in 25%. In a 2010 survey, cirrhosis was present in 98% of cases and HCV was the main aetiology (54%). Differences in HBV prevalence were found among regions. Selection of HCC treatment depends on tumour burden, liver function and performance status. Liver transplantation ( LT) is the best available curative treatment for HCC in its early stage and with compromised liver function. After modifications in priority policy, the number of patients with early HCC submitted for LT has increased in the past 5 years in Brazil. Chemoembolization is the most common initial HCC therapy in early and intermediate stages of HCC in Brazil.
- Hepatocellular Carcinoma Related to Schistosoma mansoni Infection: Case Series and Literature Review(2015) TODA, Karla Sawada; KIKUCHI, Luciana; CHAGAS, Aline Lopes; TANIGAWA, Ryan Yukimatsu; PARANAGUA-VEZOZZO, Denise Cerqueira; PFIFFER, Tulio; ROCHA, Manoel de Souza; ALVES, Venancio Avancini Ferreira; CARRILHO, Flair JoseBackground and Aims: Schistosomiasis is a major chronic disease of humans in endemic regions, and infected individuals may develop a spectrumof pathology, including hepatic fibrosis, hepatosplenomegaly, and portal hypertension. Hepatocellular carcinoma (HCC) is considered the fifth most common cancer in the world, and there is limited and controversial evidence suggesting that Schistosoma mansoni infection may be a possible risk factor for HCC. The aim of this study was to report a case series of patients with HCC and S. mansoni infection and to conduct a literature review on the topic. Methods: From January 2002 to January 2015, an institutional database was screened retrospectively to identify patients with HCC and S. mansoni infection at a single center in the Department of Gastroenterology of University of Sao Paulo School of Medicine and Hospital das Clinicas, Brazil. Results: Seven cases were included. The mean age of patients was 62.1 +/- 10.3 years; six (85.7%) were male and one (14.3%) was female. All cases had positive epidemiology, coming from endemic areas of S. mansoni infection in Brazil, and four (57.1%) had previous complications (upper gastrointestinal bleeding) related toportal hypertension or surgery intervention (splenectomy) performed more than 10 years before the HCC diagnosis. Nontumoral portal vein thrombosis was identified in five (71.4%) patients. All patients had negative serology for HCV, and four (57.1%) had positivity of HBVcore antibodies without evidence of viral replication. According to BCLC staging, one (14.3%) patient was BCLC A and received TACE instead of RFA because HCC size was >30 mm; three (42.8%) BCLC B patients received sorafenib instead of local regional treatment due to the presence of nontumoral TPV. During follow-up, all patients developed tumoral progression and died. Conclusions: It remains unclear if S. mansoni infection alone has carcinogenic potential. The available literature indicates that S. Mansoni, in the presence of HBV and HCV infections, likely acts as a cofactor for the hepatic lesion and potentiates injury.
