Previous issue date: 2013-03-15 / Renal cell carcinomas (RCCs) are among most the most lethal malignant neoplasms. Despite the evolution in the development of new drugs and imaging studies, mortality rates have increased around the world. Currently, to establish risks of mortality in RCC patients are classified according to scales and nomograms that can‗t accurately predict clinical outcomes. The association between cancer and thromboembolic events is well known for a long time. A few years ago, researchers identified tissue factor as one of the proteins responsible for these phenomena and several studies have been conducted trying to correlate the expression of tissue factor with cancer. In 2009, a study conducted by our group described the important association between the immunohistochemical expression of tissue factor and mortality in patients with Wilms' tumours. The aim of the present study was to correlate the immunohistochemical expression tissue factor with prognostic factors and mortality in 58 patients surgically treated at Hospital S?o Lucas in the years 2004 to 2007, who had been followed for at least five years. / O c?ncer renal ? uma das neoplasias malignas mais letais. As taxas de mortalidade t?m crescido mundialmente a despeito da evolu??o do diagn?stico precoce e do surgimento de novos f?rmacos ativos na terapia da doen?a sist?mica. Atualmente, para se estabelecer riscos de morbimortalidade em c?ncer renal, os pacientes s?o classificados de acordo com escalas e nomogramas que ainda n?o conseguem predizer com acur?cia a evolu??o cl?nica dos mesmos. De longa data, j? sabemos da associa??o entre fen?menos tromboemb?licos e neoplasia. H? alguns anos, pesquisadores identificaram o fator tecidual como uma das prote?nas respons?veis por estes fen?menos e desde ent?o v?rios estudos t?m sido conduzidos tentando identificar em diferentes tipos tumorais a associa??o entre fator tecidual, tromboembolismo e neoplasia. Em 2009, nosso grupo analisou a correla??o da express?o imunoistoquimica do fator tecidual com sobrevida em pacientes com tumores de Wilms. Neste estudo, houve importante associa??o entre express?o elevada do fator tecidual e pior progn?stico. O objetivo do presente trabalho foi correlacionar a express?o imunoistoquimica deste mesmo fator tecidual com fatores progn?sticos e mortalidade em 58 pacientes portadores de tumores de c?lulas claras de rim submetidos a cirurgia no Hospital S?o Lucas da PUCRS nos anos de 2004 ? 2007 e que tiveram acompanhamento por pelo menos 5 anos.
