Correlação entre os fatores prognósticos clássicos e sobrevida em cinco anos de pacientes com carcinoma da mama em uma instituição pública do estado de Sergipe

Abstract

Breast cancer is the most frequent neoplasm in females in Brazil and in the world, except for non-melanoma skin neoplasms and the first cause of death due to neoplasia in women. Due to the magnitude of this pathology, it is important to know the various factors related to the prognosis and survival of the women affected by this neoplasm. Thus, the objective of this study is to analyze the correlation between classic prognostic factors and the 5-year survival of patients with breast cancer treated at a public reference hospital in the city of Aracaju, a medium-sized city in the state of Sergipe, in the period of 2011 and 2013. The overall survival of the study was almost 85%. The variables analyzed were: histological grade, histological type, axillary lymph node involvement, staging and age at diagnosis. Among these, the only variable that presented a significant relationship with 5-year survival was the histological grade, in which Grade II patients presented lower survival (78%), while Grade III patients presented 43 survival of 81% and patients with Grade I had a probability of survival of 85%. In addition, it was detected that 61% of patients who developed distant metastases had died to the end of the study, which reinforces the idea that the presence of metastasis may negatively reflect the survival rates
