PREVALêNCIA DE C NCER DE MAMA E ASSOCIA O COM SEUS FATORES PROGNóSTICOS E PREDITIVOS DIAGNOSTICADOS NUM HOSPITAL UNIVERSITáRIO

Breast cancer is the most frequent cancer in women in Brazil. Although it is considered a cancer with relatively good prognosis, if diagnosed and treated appropriately, mortality rates from breast cancer remain high in Brazil, most likely because the disease is still diagnosed in advanced stages. The aim of this study was to evaluate the prevalence of breast cancer in a university hospital by pathological examination and the prognostic and predictive factors associated with each case, to observe the stage of diagnosis of patients. We conducted a retrospective study with selection of anatomic-pathological reports of mammary tumor excision diagnosed with breast cancer, from the University Hospital of Presidente Prudente - SP, in the period from 1998 to 2009. We collected the data related to patient age and prognostic and predictors factors. There were 183 cases of breast cancer. The highest incidence occurred between the ages of 40-49 years (29.5%) and the most frequent histological type was invasive ductal carcinoma (61.2%). In 45% of cases, the tumors were measured less than 2 cm. The majority (71%) had no metastasis to axillary lymph nodes. In 27 cases there was expression of hormone receptors and in 26 patients were overexpression of Her2/neu. It is concluded that the patients studied were diagnosed in early stage of breast cancer.
