article 44 Citação(ões) na Scopus Epidemiology of HCC in Brazil: incidence and risk factors in a ten-year cohort(2014) PARANAGUA-VEZOZZO, Denise C.; ONO, Suzane K.; ALVARADO-MORA, Monica V.; FARIAS, Alberto Q.; CUNHA-SILVA, Marlone; FRANCA, Joao I. D.; ALVES, Venancio A. F.; SHERMAN, Morris; CARRILHO, Flair JoseBackground and aim. The lack of information about hepatocellular carcinoma (HCC) in Brazil weakens health policy in preventing deaths from the illness. The aim of this study was to establish the cumulative incidence and the risk factors for hepatocellular carcinoma development in patients under a surveillance program. Material and methods. 884 patients with compensated cirrhosis were prospectively followed up for at least five years, from August 1998 until August 2008, with at least one annual ultrasonography liver examination and serum alpha fetoprotein (AFP) measurement. Results. Among 884 patients, 72 (8.1%) developed a tumor with a median follow up of 21.4 months. In the hepatocellular carcinoma group, hepatitis C virus infection was the major etiological factor (65.3%), 56.9% (41/72) were male and the mean average age was 57 +/- 10 years. The annual incidence of hepatocellular carcinoma was 2.9%. 79.2% (57/72) of HCCs were detected within Milan Criteria, and the mean survival time was 52.3 months, significantly higher than for those outside Milan, with a mean time of 40.6 months (p = 0.0003). Conclusion. The annual incidence of HCC among this large series of Brazilian cirrhotic patients was around 2.9% with a detection rate of 8.1%, or a cumulative incidence rate over five years of 14.3%. The three variables related to HCC risk were low serum albumin [HR: 0.518 (0.46-0.78)], high AFP > 20 ng/mL [HR: 3.16 (1.86-5.38)], and ethnicity (Brazilian-East Asian descendants vs. other mixed Brazilian ethnicities) [HR: 2.86 (1.48-5.53)].article 2 Citação(ões) na Scopus 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.conferenceObject Diagnostic Accuracy of Elastography, Alfa Fetoprotein and Ultrasound Findings in Screening for Hepatocellular Carcinoma in Patients on Liver- Transplant Waiting List(2014) NACIF, Lucas S.; VEZOZZO, Denise C.
