    Clinical and pathological evaluation of fibrolamellar hepatocellular carcinoma: a single center study of 21 cases
    (2015) CHAGAS, Aline Lopes; KIKUCHI, Luciana; HERMAN, Paulo; ALENCAR, Regiane S. S. M.; TANI, Claudia M.; DINIZ, Marcio Augusto; PUGLIESE, Vincenzo; ROCHA, Manoel de Souza; D'ALBUQUERQUE, Luiz Augusto Carneiro; CARRILHO, Flair Jose; ALVES, Venancio A. F.
    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.

    Re-Transplantation, Higher Creatinine Levels in Hepatitis C Virus Patients, and Donor Age Are Predictors of Mortality in Long-Term Analysis of Late Acute Rejection in Liver Transplantation
    (2017) NACIF, Lucas Souto; PINHEIRO, Rafael Soares; PECORA, Rafael Antonio de Arruda; TANIGAWA, Ryan Yukimatsu; ROCHA-SANTOS, Vinicius; ANDRAUS, Wellington; ALVES, Venancio Avancini Ferreira; D'ALBUQUERQUE, Luiz Carneiro
    Background: Late acute rejection (LAR) differs in its clinical and histological presentation and management from early acute rejection. This clinical entity is not completely understood; thus, we aimed to identify significant prognostic factors that can influence post-transplant survival in LAR patients. The purpose of this study was to evaluate the incidence and post-transplant survival of patients from a single center with a focus on late acute rejection. Material/Methods: From January 2002 to June 2013, all liver biopsies from patients with rejection were scored using the Banff criteria. The groups were compared, and simple and multiple logistic regression and survival curves were created. Results: A total of 779 liver transplants were performed; 585 patients with no rejections and 194 patients with rejections were analyzed. The overall incidence of LAR was 6.7%, and there was a higher prevalence of early acute cellular rejection than LAR. The mean time to LAR was 564 days (median 214 days, range 91-2642). LAR had a more severe grade (35.3%) than early acute rejection (23.5%). The survival rates were similar between both modalities for the long-term period. Worse mortality rates were observed in liver re-transplantation (HR 4.77; p<0.0001); in hepatitis C virus patients with increased creatinine levels (HR 22.48; p=0.016); and in donors > 41 years of age (OR 2.1; p=0.047) in a long-term analysis of LAR. Conclusions: Liver re-transplantation, higher creatinine levels in hepatitis C virus patients, and donor age were predictors of mortality in this long-term analysis of late acute rejection in liver transplantation.

    Percutaneous radiofrequency ablation for early hepatocellular carcinoma: Risk factors for survival
    (2014) KIKUCHI, Luciana; MENEZES, Marcos; CHAGAS, Aline L.; TANI, Claudia M.; ALENCAR, Regiane S. S. M.; DINIZ, Marcio A.; ALVES, Venancio A. F.; D'ALBUQUERQUE, Luiz Augusto Carneiro; CARRILHO, Flair Jose
    AIM: To evaluate outcomes of radiofrequency ablation (RFA) therapy for early hepatocellular carcinoma (HCC) and identify survival-and recurrence-related factors. METHODS: Consecutive patients diagnosed with early HCC by computed tomography (CT) or magnetic resonance imaging (MRI) (single nodule of <= 5 cm, or multi-(up to 3) nodules of <= 3 cm each) and who underwent RFA treatment with curative intent between January 2010 and August 2011 at the Instituto do Cancer do Estado de Sao Paulo, Brazil were enrolled in the study. RFA of the liver tumors (with 1.0 cm ablative margin) was carried out under CT-fluoro scan and ultrasonic image guidance of the percutaneous ablation probes. Procedure-related complications were recorded. At 1-mo post-RFA and 3-mo intervals thereafter, CT and MRI were performed to assess outcomes of complete response (absence of enhancing tissue at the tumor site) or incomplete response (enhancing tissue remaining at the tumor site). Overall survival and disease-free survival rates were estimated by the Kaplan-Meier method and compared by the log rank test or simple Cox regression. The effect of risk factors on survival was assessed by the Cox proportional hazard model. RESULTS: A total of 38 RFA sessions were performed during the study period on 34 patients (age in years: mean, 63 and range, 49-84). The mean follow-up time was 22 mo (range, 1-33). The study population showed predominance of male sex (76%), less severe liver disease (Child-Pugh A, n = 26; Child-Pugh B, n = 8), and single tumor (65%). The maximum tumor diameters ranged from 10 to 50 mm (median, 26 mm). The initial (immediately post-procedure) rate of RFA-induced complete tumor necrosis was 90%. The probability of achieving complete response was significantly greater in patients with a single nodule (vs patients with multi-nodules, P = 0.04). Two patients experienced major complications, including acute pulmonary edema (resolved with intervention) and intestinal perforation (led to death). The 1- and 2-year overall survival rates were 82% and 71%, respectively. Sex, tumor size, initial response, and recurrence status influenced survival, but did not reach the threshold of statistical significance. Child-Pugh class and the model for end-stage liver disease score were identified as predictors of survival by simple Cox regression, but only Child-Pugh class showed a statistically significant association to survival in multiple Cox regression analysis (HR = 15; 95% CI: 3-76 mo; P = 0.001). The 1- and 2-year cumulative disease-free survival rates were 65% and 36%, respectively. CONCLUSION: RFA is an effective therapy for local tumor control of early HCC, and patients with preserved liver function are the best candidates.

    Quantification of C4d deposition and hepatitis C virus RNA in tissue in cases of graft rejection and hepatitis C recurrence after liver transplantation
    (2015) SONG, Alice Tung Wan; MELLO, Evandro Sobroza de; ALVES, Venancio Avancini Ferreira; CAVALHEIRO, Norma de Paula; MELO, Carlos Eduardo; BONAZZI, Patricia Rodrigues; TENGAN, Fatima Mitiko; FREIRE, Maristela Pinheiro; BARONE, Antonio Alci; D'ALBUQUERQUE, Luiz Augusto Carneiro; ABDALA, Edson
    Histology is the gold standard for diagnosing acute rejection and hepatitis C recurrence after liver transplantation. However, differential diagnosis between the two can be difficult. We evaluated the role of C4d staining and quantification of hepatitis C virus (HCV) RNA levels in liver tissue. This was a retrospective study of 98 liver biopsy samples divided into four groups by histological diagnosis: acute rejection in patients undergoing liver transplant for hepatitis C (RejHCV+), HCV recurrence in patients undergoing liver transplant for hepatitis C (HCVTx+), acute rejection in patients undergoing liver transplant for reasons other than hepatitis C and chronic hepatitis C not transplanted (HCVTx-). All samples were submitted for immunohistochemical staining for C4d and HCV RNA quantification. Immunoexpression of C4d was observed in the portal vessels and was highest in the HCVTx- group. There was no difference in C4d expression between the RejHCV+ and HCVTx+ groups. However, tissue HCV RNA levels were higher in the HCVTx+ group samples than in the RejHCV+ group samples. Additionally, there was a significant correlation between tissue and serum levels of HCV RNA. The quantification of HCV RNA in liver tissue might prove to be an efficient diagnostic test for the recurrence of HCV infection.

    ABSTRACT Hepatocellular carcinoma (HCC) is one of the leading causes of cancer-related mortality worldwide. The Brazilian Society of Hepatology (SBH) published in 2015 its first recommendations about the management of HCC. Since then, new data have emerged in the literature, prompting the governing board of SBH to sponsor a single-topic meeting in August 2018 in São Paulo. All the invited experts were asked to make a systematic review of the literature reviewing the management of HCC in subjects with cirrhosis. After the meeting, all panelists gathered together for the discussion of the topics and the elaboration of updated recommendations. The text was subsequently submitted for suggestions and approval of all members of the Brazilian Society of Hepatology through its homepage. The present manuscript is the final version of the reviewed manuscript containing the recommendations of SBH.

    m-RECIST at 1 month and Child A are survival predictors after percutaneous ethanol injection of hepatocellular carcinoma
    (2014) SILVA, Mauricio F.; CARRILHO, Flair J.; PARANAGUA-VEZOZZO, Denise C.; CAMPOS, Luciana T.; NACIF, Lucas S.; DINIZ, Marcio A.; FARIAS, Alberto Q.; ALVES, Venancio A. F.; D'ALBURQUERQUE, Luis A. C.; ONO, Suzane K.
    Background and aims. Percutaneous ethanol injection (PEI) is a well-established therapeutic option in patients with cirrhosis and hepatocellular carcinoma (HCC). The modified-Response Evaluation Criteria in Solid Tumors (m-RECIST) are an important tool for the assessment of HCC response to therapy. The aim was to evaluate whether HCC response according to the m-RECIST criteria could be an effective predictor of Long-term survival in Barcelona Clinic Liver Cancer (BCLC) stage 0 and A HCC patients undergoing PEI. Material and methods. 79 patients were followed-up for median time of 26.8 months. HCC diagnosis was based on the,current guidelines of the American Association for Study of the Liver Diseases (AASLD) and European Association for Study of the Liver (EASL). Patient survival was calculated from the first PEI session to the end of the follow-up. Results. The 1-, 3-, and 5-year overall survival rates were 79, 48 and 37%, respectively. In the multivariate analysis, Child-Pugh-Turcotte (CPT) (p = 0.022) and the response to m-RECIST criteria (p = 0.016) were associated with patient survival. CPT A patients who achieved Complete Response (CR) 1 month after PEI presented a 5-year survival rate of 55%. By contrast, the worst scenario, the group with CPT B but without CR had a 5-year survival rate of 9%, while the group with either CPT A or CR as a survival predictor had a 5-year survival rate of 31%. In conclusion, in BCLC stage 0 and A HCC-patients, m-RECIST at 1 month and Child A may predict survival rates after PEI.

    Steatosis and steatohepatitis found in adults after death due to non-burn trauma
    (2019) REIS-JUNIOR, Paulo; TANIGAWA, Ryan; MESQUITA, Gustavo Heluani Antunes de; BASAN, Natalia; ALVES, Venancio; D'ALBUQUERQUE, Luiz Augusto Carneiro; ANDRAUS, Wellington
    OBJECTIVE: With the increasing prevalence of steatosis, the number of steatotic liver grafts from deceased donors is also increasing. Thus, determining the prevalence and the population risk factors of steatosis may assist in risk stratification. The aim of this study was to evaluate the prevalence and predictors of steatosis and steatohepatitis among livers from adults who died due to non-burn trauma. METHODS: Specimens were collected from 224 adults undergoing autopsy at a regional autopsy referral center from September 2011 to April 2013. Histopathological examination was performed on six samples obtained from different lobes of each liver. The outcomes of interest were the presence of steatosis, steatohepatitis, NASH inflammation and NASH fibrosis. The main predictors were body mass index, abdominal circumference, liver weight and volume, presence of cholelithiasis, and siderosis. Our modeling strategy made use of a series of generalized linear models with a binomial family. RESULTS: Our sample had a mean age of 40 years; steatosis was diagnosed in 48.2% of cases, and steatohepatitis was diagnosed in 2.7%. The presence of a high proportion of fatty changes was more prevalent among males and older individuals, with the most affected age group being 41-60 years. When evaluating the crude odds ratio for steatosis, the factors significantly associated with an increased risk of steatosis were greater abdominal circumference, BMI, and liver weight and the presence of siderosis. CONCLUSION: Our study reinforces the role of older age, obesity and hepatomegaly as predictors of fatty liver disease. These variables should be considered in the assessment of fatty changes in the livers of potential liver donors.
