Survival in women with breast cancer. Hospital “Jose Ramon Lopez Tabrane”.Province of Matanzas. 2010-2015

Abstract

Introduction: in the last three years, mortality rates due to breast cancer in the female sex in Cuba slightly decreased, but studies of this disease survival have not been carried out in the province of Matanzas.

Objectives: to evaluate the behavior of the global survival time of this series at the 5^th year and to assess survival according to chosen variables.

Material and method: a retrospective, longitudinal, observational descriptive study was carried out; 288 women diagnosed with breast cancer took part on it; they were diagnosed in the mastology consultation of the hospital “Jose Ramon Lopez Tabrane”, province of Matanzas during the period January 1^st 2010- December 31^st 2015. The Kaplan-Meier method was used to determine the global survival time at the 5^th year according to chosen variables.  The comparison of the different curves for the exposition variables was made using the Log Rank test. The test value higher than 1 and p < 0.05 was considered statistically significant.

Results: global survival at the 5^th year was 66 %. There are survival rates well below the international standards for the stage III (37 %) and stage IV (0) patients. Global survival significantly decreases insofar as the number of affected ganglia and the size of the tumor at the moment of the diagnosis increase.

Conclusions: global survival at the 5^th year was lower than the one recorded in most of the consulted international studies.  There is a remarkable decrease of survival in patients with disease advanced clinical stages: III and IV.
