- Association Between GATA3 and Histopathological and Immunohistochemical Parameters in Early-Infiltrating Breast Carcinomas(2022) SOUZA, Priscila de Medeiros; CARVALHO, Filomena Marino; AGUIAR, Fernando N.; GAGLIATO, Debora; BARROS, Alfredo Carlos Simoes Dornellas deObjective: This study evaluated the frequency of GATA-binding protein 3 (GATA3) expression in early breast cancer and its relationship with histopathological and immunohistochemical parameters. Materials and Methods: GATA3 was analysed by immunohistochemistry in histological sections of rumors from 105 female patients, with histological diagnosis of invasive breast carcinoma (BC), at clinical stages I, II and IIIA, who underwent primary surgical treatment. GATA3 nuclear expression was determined as the percentage of positive tumor cells and further categorized as high (positive expression in more than 95% of cells) or non-high (negative or low positive expression in up to 95% of rumor cells). GATA3 expression was analysed according to the patient age, tumor and node pathological stage, histological type, histological and nuclear grade, lymphovascular invasion, and estrogen receptor (ER), progesterone receptor (PR), androgen receptor (AR), human epidermal growth factor 2 (HERZ) status, and Ki-67 expression. Results: GATA3 expression was positive in 103 cases (98.1%). High expression was significantly associated with low histological and nuclear grade, positive hormonal receptors, and less proliferative activity based on Ki-67 expression. A prominent feature was that 94.7% of the ER-posirive/HER2-negative cases presented high-GATA3 expression, as 94.0% of the rumors showing high-GATA3 were ER-positive. In ER-negative/HER2-positive or ER-negative/HER2- negative, high-GATA3 was present in 25% while 75% were non-high-GATA3 compared with ER-positive/HER2- negative (4.1%) and ER-positive/HER2-positive (20%). Proliferative activity in triple-negative breast cancer tended to be higher among rumors with low-GKIA3, irrespective of AR expression. In the group of ER-positive/HER2-negative tumors only three cases were low-GATA3 (85% and 80%), both with high proliferative activity. Conclusion: High GATA3 expression is associated with favorable histopathologic and immunohistochemical BC prognostic factors.
- Recommendations for the treatment of vulvar cancer in settings with limited resources: Report from the International Gynecological Cancer Society consensus meeting(2022) MALUF, Fernando Cotait; ZIBETTI, Graziela Dal Molin; PAULINO, Eduardo; MELO, Andreia Cristina de; RACY, Douglas; FERRIGNO, Robson; USON JUNIOR, Pedro Luiz Serrano; RIBEIRO, Reitan; MORETTI, Renato; SADALLA, Jose Carlos; RODRIGUES, Angelica Nogueira; CARVALHO, Filomena Marino; BAIOCCHI, Glauco; CALLEGARO-FILHO, Donato; ANGIOLI, RobertoIntroductionDue to scant literature and the absence of high-level evidence, the treatment of vulvar cancer is even more challenging in countries facing limited resources, where direct application of international guidelines is difficult. Recommendations from a panel of experts convened to address some of these challenges were developed. MethodsThe panel met in Rio de Janeiro in September 2019 during the International Gynecological Cancer Society congress and was composed of specialists from countries in Africa, Asia, Eastern Europe, Latin America, and the Middle East. The panel addressed 62 questions and provided recommendations for the management of early, locally advanced, recurrent, and/or metastatic vulvar cancer. Consensus was defined as at least 75% of the voting members selecting a particular recommendation, whereas a majority vote was considered when one option garnered between 50.0% and 74.9% of votes. Resource limitation was defined as any issues limiting access to qualified surgeons, contemporary imaging or radiation-oncology techniques, antineoplastic drugs, or funding for the provision of contemporary medical care. ResultsConsensus was reached for nine of 62 (14.5%) questions presented to the panel, whereas a majority vote was reached for 29 (46.7%) additional questions. For the remaining questions, there was considerable heterogeneity in the recommendations. ConclusionThe development of guidelines focusing on areas of the world facing more severe resource limitations may improve medical practice and patient care.
- Recommendations for the prevention, screening, diagnosis, staging, and management of cervical cancer in areas with limited resources: Report from the International Gynecological Cancer Society consensus meeting(2022) MALUF, Fernando Cotait; MOLIN, Graziela Zibetti Dal; MELO, Andreia Cristina de; PAULINO, Eduardo; RACY, Douglas; FERRIGNO, Robson; USON JUNIOR, Pedro Luiz Serrano; RIBEIRO, Reitan; MORETTI, Renato; SADALLA, Jose Carlos; NOGUEIRA-RODRIGUES, Angelica; CARVALHO, Filomena Marino; BAIOCCHI, Glauco; CALLEGARO-FILHO, Donato; ABU-RUSTUM, Nadeem R.IntroductionNearly 85% of cervical cancer new cases are diagnosed in limited resources countries. Although several strategies have been proposed to reduce the disease burden, challenges remain to provide the best possible care. We report recommendations from an expert consensus meeting convened to address from prevention to management of cervical cancer in limited resources countries. MethodsThe expert panel, composed by invited specialists from 38 developing countries in Africa, Asia, Eastern Europe, Latin America, and the Middle East, convened in Rio de Janeiro in September 2019, during the Global Meeting of the International Gynecological Cancer Society (IGCS). Panel members considered the published scientific evidence and their practical experience on the topics, as well as the perceived cost-effectiveness of, and access to, the available interventions. The focus of the recommendations was on geographic regions rather than entire countries because medical practice varies considerably in the countries represented. Resource limitation was qualified as limited access to qualified surgeons, contemporary imaging or radiation-oncology techniques, antineoplastic drugs, or overall funding for provision of state-of-the-art care. Consensus was defined as at least 75% of the voting members selecting a particular answer of the multiple-choice questionnaire, whereas the majority vote was considered as 50% to 74.9%. ResultsConsensus was reached for 25 of the 121 (20.7%) questions, whereas for 54 (44.6%) questions there was one option garnering between 50% to 74.9% of votes (majority votes). For the remaining questions, considerable heterogeneity in responses was observed. DiscussionThe implementation of international guidelines is challenging in countries with resource limitations or unique health-care landscapes. The development of guidelines by the health care providers in those regions is more reflective of the reality on the ground and may improve medical practice and patient care. However, challenges remain toward achieving that goal at political, economic, social, and medical levels.
