Estudos Brasileiros Apresentados nos Encontros Anuais da ASCO entre 2001 e 2007: Aumento de Produção, com Baixa Taxa de Publicação

Abstract

A pesquisa clínica está crescendo no Brasil, e muitos dos estudos recentes importantes no campo da oncologia incluíram um número substancial de pacientes brasileiros. Entretanto, é difícil estabelecer até que ponto ocorreu um aumento proporcional da pesquisa originada no Brasil. Objetivou-se responder a essa questão através de uma análise bibliométrica de estudos brasileiros apresentados nos Encontros Anuais da American Society of Clinical Oncology (ASCO). Foi realizada uma busca manual dos 24.998 abstracts publicados nos Anais do Encontro da ASCO durante os anos de 2001 a 2007. Os abstracts definidos como brasileiros foram aqueles em que pelo menos dois terços das instituições eram do Brasil. Foram identificados 244 estudos brasileiros (0,97% do total). Houve um aumento significativo da proporção de estudos brasileiros ao longo dos anos compreendidos pelo estudo (P=0,017). Dos 244 estudos, 69,6% não foram apresentados no encontro, aparecendo apenas nos Anais como publication only. Depois de um seguimento mediano de 35 meses, apenas 16,9% dos abstracts de 2001 a 2005 foram publicados em revistas indexadas nas bases de dados Medline e Lilacs, com um tempo mediano até a publicação de 13,5 meses. Este estudo demonstra empiricamente o aumento da produção científica por parte dos pesquisadores brasileiros na área de oncologia, mas sugere também que é necessário um esforço para aumentar a taxa de publicação dos estudos.

Publication rate of scientific papers presented at the largest event on breast cancer research in Latin America

“…During this period, the dissemination and awards of the event increased. Thus, one of the justifications for this trend is the increase in Brazilian participation in international congresses, such as the San Antonio Breast Cancer Symposium and American Society of Clinical Oncology (ASCO) Annual Meeting, which give researchers greater prestige and visibility [1,6]. Given this information, researchers should be encouraged to present their abstracts at Brazilian events and, later, receive institutional support to publish them.…”

“…This symposium was selected because it is the largest event on breast cancer research in Brazil and Latin America. The 2012-2017 period was selected to allow an interval of 3 years after presentation, since this period is considered an appropriate time for the publication of abstracts presented at a congress [1]. In 2011, the BBCS event was not held because the city of Goiânia was the venue for the Brazilian Congress of Mastology.…”

“…Disseminating knowledge gained from scientific research is the first step for healthcare advancement. Safe and reliable sources of information are of vital importance, and priority must be given to scientific studies conducted with appropriate methodology [1][2][3]. In recent years, scientific development in the field of breast cancer has contributed to progress in the diagnosis of the disease, to consolidating new treatment strategies and to achieving more favourable oncologic outcomes [3][4][5].…”

“…Among other benefits, medical congresses promote continued education, the discussion of clinical cases, the formulation of institutional protocols and the launching of specialised bibliographic material, as well as allowing contact between individuals from different geographic regions [6]. In this respect, bibliometric studies within any given medical speciality can contribute by providing indicators related to the production and dissemination of scientific knowledge [1,7]. These studies also allow the progress achieved in any given subject or topic within each area of interest to be evaluated [1,2,6].…”
