Abstract
Introduction: Breast cancer is the most common oncological pathology in the female population worldwide, it has been determined that its prognosis is linked to the diagnostic tumor stage, histological type and systemic treatment that is applied according to the molecular subtype. The objective of this study is to identify the association of the expression of hormonal receptors, HER2 / neu and Ki67 with the survival of patients with breast cancer. Methods: A descriptive, retrospective study was carried out at the National Oncology Institute Dr. Juan Tanca Marengo in 284 patients diagnosed with breast cancer from January 2006 to December 2013. Age, histological diagnosis, clinical stage, molecular subtypes and survival variables were analyzed. Results: The average age was between 40 and 65 years, The most frequent histopathological diagnosis was infiltrating ductal carcinoma in 236 patients, the percentage of Ki67 was higher than 14% in 60% of those killed, the most frequent molecular subtype luminal B HER2 was positive with 95 cases and higher mortality in negative triples with 12.76%. Conclusion: Ki67 is a useful marker to assess the prognosis of the patient, the molecular classification of the tumor will allow directing the specific treatment and thereby obtaining the clinical re-staging of the patient.
