    A phase II trial with anti-Lewis-Y monoclonal antibody (hu3S193) for the treatment of platinum resistant/refractory ovarian, fallopian tube and primary peritoneal carcinoma
    (2015) SMALETZ, Oren; DIZ, Maria D. P. E.; CARMO, Claudio C. do; SABBAGA, Jorge; CUNHA-JUNIOR, Geraldo F.; AZEVEDO, Sergio J.; MALUF, Fernando C.; BARRIOS, Carlos H.; COSTA, Ronaldo L.; FONTANA, Ana G.; MADRIGAL, Vivian; WAINSTEIN, Alberto J.; YEDA, Fernanda P.; ALVES, Venancio A.; MORO, Ana M.; BLASBALG, Roberto; SCOTT, Andrew M.; HOFFMAN, Eric W.
    Objectives. The primary objective was to evaluate the clinical efficacy of hu3S193, a humanized monoclonal antibody against the Lewis-Y antigen, in patients with platinum resistant/refractory ovarian, fallopian tube and primary peritoneal carcinoma. Secondary objectives were safety and pharmacokinetics. In addition, we sought to determine the potential interaction of clinical benefit and patient characteristics. Methods. This two-stage, multicenter, single arm, phase II trial enrolled eligible patients to receive hu3S193 weekly at a dose of 20 mg/m(2) intravenously for 8 weeks (1 cycle) to a maximum of 3 cycles. Efficacy was measured as clinical benefit rate (objective response or stable disease for at least 24 weeks). Results. 26 of 31 patients were eligible for efficacy analysis. No complete/partial responses were observed. Six patients had stable disease for 24+ weeks [clinical benefit rate 23% (95% CI = 9.77%-46.71%)]. Median PFS was 8.4 weeks (95% CI = 6.0 to 16.1). Median PFS differed between patients with no ascites and no visceral disease and patients with ascites and/or visceral disease [16.1 vs. 8.1 weeks (p = 0.0058)]. The most commonly reported treatment-related adverse events were fatigue (19.3%) and nausea (16.2%). Allergic reactions occurred in 6 patients (5 with Grade 1/2; 1 with Grade 3). Conclusions. Hu3S193 lacked sufficient activity in the first stage of the study to open enrollment to the second stage. However, based on the longer PFS in patients with no ascites and no visceral disease, consolidation strategies in platinum sensitive disease are currently being tested. (C) 2015 Elsevier Inc.

    (2018) MORON, Roberson A.; JACOB, Carlos Eduardo; BRESCIANI, Claudio Jose Caldas; SIMOES, Kleber; ALVES, Venancio Avancini Ferreira; IRYA, Kyoshi; GAMA-RODRIGUES, Joaquim; CECCONELLO, Ivan; LONGATTO-FILHO, Adhemar; ZILBERSTEIN, Bruno
    The aim of the present study was to determine the clinical significance of p53 and p21(ras) p21(wafl), p27(kip1) and p16(ink4a) expression in cases of early gastric cancer. A total of 81 patients who had undergone gastrectomy with D2 lymphadenectomy between 1971 and 2004 were retrospectively investigated. The immunohistochemical expression of p21ras, p53, p21waf1.cip1, p27kip1 and p16ink4a in the tissues was evaluated. In normal, metaplastic and tumoral mucosa, p53 was positive in 53, 87.3, and 87.1% of the cases, respectively. In the same tissues, p21ras was positive in 85.3, 86 and 96.8%, respectively. Positivity for p16ink4a was detected in 46.3, 91.1 and 86% of the cases, respectively, whereas p27kip1 was positive in 60, 94.7 and 95.3%, and p21wafl/ cip1 was positive in 32.4, 72.7 and 71.4% of the cases, respectively. All the tumors were positive for p53. Tumors with lymph node invasion presented with overexpression (+ 4) of p53 in 47% of the cases vs. 17% of patients who did not have lymph node involvement. Therefore, higher expression of p53, p21ras and p21wafl/ cip1 in the tumor exhibited a statistically significant association with lymph node involvement.

    Middle ear adenoma with neuroendocrine differentiation: relate of two cases and literature review
    (2013) BITTENCOURT, Aline Gomes; TSUJI, Robinson Koji; CABRAL JUNIOR, Francisco; PEREIRA, Larissa Vilela; FONSECA, Anna Carolina de Oliveira; ALVES, Venâncio; BENTO, Ricardo Ferreira
    INTRODUCTION: Adenomas with neuroendocrine differentiation are defined as neuroendocrine neoplasms, and they are rarely found in the head and neck. OBJECTIVE: To describe two cases of a middle ear adenoma with neuroendocrine differentiation, with a literature review. CASE REPORT: Patient 1 was a 41-year-old woman who presented with a 3-year history of left aural fullness associated with ipsilateral ""hammer beating"" tinnitus. Patient 2 was a 41-year-old male who presented with unilateral conductive hearing loss. CONCLUSION: Adenoma with neuroendocrine differentiation of the middle ear is a rare entity, but it should be considered in patients with tinnitus, aural fullness, and a retrotympanic mass and remembered as a diferential diagnosis of tympanic paraganglioma.

    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 Jose
    Background 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)].

    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.
