- 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.

C.; LONGATTO-FILHO, A.; CAMPOS, P. B. De; OLIVEIRA, C. P.; STEFANO, J. T.; MARTINS-FILHO, S. N.; CHAGAS, A. L.; HERMAN, P.; D'ALBUQUERQUE, L. C.; ALVARES-DA-SILVA, M. Reis; CARRILHO, F. J.; BALTAZAR, F.; ALVES, V. A. F.Introduction: Hepatocellular carcinoma (HCC) has been associated to non-alcoholic fatty liver disease (NAFLD). We sought to investigate the immunoexpression of several glycolytic metabolism-associated markers in patients with HCC associated to NAFLD and associate these factors to their clinical-pathological characteristics. Methods: We evaluated 35 HCC specimens from 21 patients diagnosed with non-alcoholic steatohepatitis (NASH) undergoing liver resection (12 patients), liver transplantation (8 patients), or both (1 patient). Histological features, clinical aspects, demographic and biochemical data, as well as the immunohistochemical reactivity for monocarboxylate transporters 1, 2, and 4; their chaperone CD147; carbonic anhydrase IX; and glucose transporter-1 (GLUT1) were assessed. Results: Metabolic-associated cirrhosis was present in 12 of the 21 patients (8 child A and 4 child B scores). From 9 patients without cirrhosis, 3 presented NASH F3 and 6 NASH F2. Sixteen (76%) had diabetes mellitus, 17 (81%) arterial hypertension, and 19 (90%) body mass index above 25 kg/m2; 8 (38%) had dyslipidemia. From 35 nodules, steatosis was found in 26, ballooning in 31 nodules, 25 of them diagnosed as steatohepatitic subtype of HCC. MCT4 immunoexpression was associated with extensive intratumoral fibrosis, advanced clinical stages, and shorter overall survival. GLUT1 was noticeable in nodules with extensive intratumoral steatosis, higher intratumoral fibrosis, and advanced clinical stages. Immunohistochemical expression of the metabolic biomarkers MCT4 and GLUT1 was higher in patients with Barcelona-clinic liver cancer B or C. GLUT1 correlated with higher degree of steatosis, marked ballooning, intratumoral fibrosis, and higher parenchymal necroinflammatory activity. Conclusion: Our data indicate that the expression of the glycolytic phenotype of metabolic markers, especially GLUT1 and MCT4, correlates with a more severe course of HCC occurring in NASH patients.
- Hypolactasia is associated with insulin resistance in nonalcoholic steatohepatitis(2016) MAZO, Daniel Ferraz de Campos; MATTAR, Rejane; STEFANO, Jose Tadeu; SILVA-ETTO, Joyce Matie Kinoshita da; DINIZ, Marcio Augusto; DUARTE, Sebastiao Mauro Bezerra; RABELO, Fabiola; LIMA, Rodrigo Vieira Costa; CAMPOS, Priscila Brizolla de; CARRILHO, Flair Jose; OLIVEIRA, Claudia P.AIM To assess lactase gene (LCT)-13910C>T polymorphisms in Brazilian non-alcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH) patients in comparison with healthy controls. METHODS This was a transverse observational clinical study with NAFLD patients who were followed at the Hepatology Outpatient Unit of the Hospital das Clinicas, Sao Paulo, Brazil. The polymorphism of lactase non-persistence/ lactase persistence (LCT-13910C>T) was examined by PCR-restriction fragment length polymorphism technique in 102 liver biopsy-proven NAFLD patients (steatosis in 9 and NASH in 93) and compared to those of 501 unrelated healthy volunteers. Anthropometric, clinical, biochemical and liver histology data were analyzed. Continuous variables were compared using the t or Mann-Whitney tests, and categorical data were compared with the Fisher's exact test. Univariate logistic regression and multivariate logistic regression adjusted for gender and age were performed. RESULTS No differences in the LCT-13910 genotype frequencies were noted between the NAFLD patients (66.67% of the patients with steatosis were CC, 33.33% were CT, and none were TT; 55.91% of the patients with NASH were CC, 39.78% were CT, and 4.3% were TT; P = 0.941) and the healthy controls (59.12% were CC, 35.67% were CT, and 5.21% were TT) or between the steatosis and NASH patients. That is, the distribution of the lactase non-persistence/lactase persistence polymorphism (LCT-13910C>T) in the patients with NAFLD was equal to that in the general population. In the NASH patients, the univariate analysis revealed that the lactase nonpersistence (low lactase activity or hypolactasia) phenotype was associated with higher insulin levels (23.47 +/- 15.94 mu U/mL vs 15.8 +/- 8.33 mu U/mL, P = 0.027) and a higher frequency of insulin resistance (91.84% vs 72.22%, P = 0.02) compared with the lactase persistence phenotype. There were no associations between the LCT genotypes and diabetes (P = 0.651), dyslipidaemia (P = 0.328), hypertension (P = 0.507) or liver histology in these patients. Moreover, in the NASH patients, hypolactasia was an independent risk factor for insulin resistance even after adjusting for gender and age [OR = 5.0 (95%CI: 1.35-20; P = 0.017)]. CONCLUSION The LCT-13910 genotype distribution in Brazilian NAFLD patients was the same as that of the general population, but hypolactasia increased the risk of insulin resistance in the NASH patients.
