Clinical pathological characteristics and survival of patients with breast cancer attended at IMAT (Montería).

Características clínico-patológicas y sobrevida de las pacientes con cáncer de mama atendidas en el Instituto Médico de Alta Tecnología (IMAT) (Montería).

Breast cancer is a public health problem that deserves special attention because of its incidence and its profound social impact because it affects women, the fundamental axis of the modern family. Objective: The aim of this study was to describe clinical-pathological characteristics and survival rate of patients with breast cancer treated at IMAT Oncomédica. Methods: Descriptive, retrospective observational study of 506 patients with breast cancer, where socioeconomic, histological variables, hormone receptor and HER2 expression, treatments and relapses were analyzed. Results: The mean age at diagnosis was 54 years. The predominant histological subtype was ductal and most patients had an early disease. The 5-year overall survival rate in all patients in the study was 77.6%. The pathological response rate to neoadjuvant chemotherapy was 11% in all patients. The 6-year overall survival rate in patients receiving neoadjuvant chemotherapy was greater in those who achieved complete pathologic response (74.4%) versus those who did not achieve complete pathologic response (62.1%) (p = 0.044). Conclusions: This research was carried out at IMAT, a cancer reference center for Córdoba. This is the first study to determine the clinical and pathological characteristics of people with breast cancer in this region, with results of overall survival rate similar to Latin American countries and close to the rates of Europe and the United States.
