Evaluation of starting treatment time, histopathological staging and positivity of biomarkers (ER, PR, HER-2) in 3,566 patients treated by SUS from 2012 to 2014, at Perola Byington Hospital

Abstract

The purpose of the study was the time to start treatment, age, surgical staging and the positivity of biomarkers (ER, PR and HER-2) in 3,566 patients with breast carcinoma served by SUS from January 2012 to December 2014 in Perola Byington Hospital (SP), Brazil. The median time to initiation of therapy was 32 days. The age of patients ranged from 12 to 98 years with 49 patients (1.4%) with less than 30 years, 396 (11.1%) between 30 and 39 years, 1,002 (28.1%) between 40 and 49 years, 1,737 (48.7%) between 50 and 69 years and 382 (10.7%) over 70 years. As to staging, 8.1% of the tumors were treated “in situ”, 17.2% were in stage I, 43.1% in II, III and 28.6% in only 3% in Stage IV. The positivity of the estrogen receptor and/or progesterone was 72.9% and the HER-2 17.4%. Tumors luminal A and B represented by 23 and 46% and triple-negative, 17.5% of cases. The data show a significant number of patients with tumors in situ and prevalence of patients in Stage I and II.
