Abstract:

The aim of this study was to evaluate the effectiveness in a real-world study of adjuvant trastuzumab in women with positive HER-2 initial breast cancer in overall survival and relapse-free survival. A retrospective cohort study was conducted in women with HER-2 positive breast cancer with trastuzumab complementary to treatment recruitedJuly 2012 to May 2017 and follow-up until July 2021. The death rate was 2.62 per 100 person/year and the incidence rate of recurrence was 7.52 per 100 person/year. The probability survival at 8.7 years was 85.9% while the probability of relapse-free survival in the same period was 62.8%. The use of trastuzumab proved to be effective in the adjuvant treatment of breast cancer in a public health service in southern Brazil. Prognostic factors associated with worse overall survival or relapse did not influence the natural history of the disease, except locally advanced disease at the beginning of treatment. The data presented may prove to be useful in helping to make decisions about whether or not to use trastuzumab in the treatment of initial or locally advanced breast cancer in the Brazilian public health service.
