Objectives Evaluate the epidemiological aspects of patients with endometrial cancer, based on statistics from the Oncology Gynecology Center of Santa Marcelina Hospital in Sao Paulo, Brazil between 2011 to 2018.

Methods Evaluate the epidemiological aspects of patients with endometrial cancer (EC), based on statistics from the Oncology Gynecology Center of Santa Marcelina Hospital in Sao Paulo, Brazil between 2011 to 2018.

Results The median age at diagnosis was 63 years and the diagnosed cases were predominantly white ethnicity (51%). Bleeding after menopause was the most frequent symptom reported (77.8%). Among the cases analyzed, 36 nulliparous patients presented endometrial cancer (15%). The most prevalent histological type was endometrioid adenocarcinoma (66.1%). The most frequent tumor staging was IA with 30.9%, followed by IB 18.83%, II 2%, IIIA 8%, IIIB 9.2% IIIC1 4.6%, IIIC2 6.69%, IVA 0.42% and IVB 16.74%. Surgical staging with hysterectomy and bilateral adnexectomy represented 76.9% and the most frequent adjuvant treatment was brachytherapy (53.1%). Seventy patients underwent brachytherapy and pelvic radiotherapy (29.9%) and 38 patients underwent adjuvant brachytherapy, radiotherapy and chemotherapy as an adjuvant (15.9%). An overall survival rate of 65% and a mortality rate of 29% over the 5-year period have been identified.

Conclusions EC is the eighth most frequent gynecological tumor in Brazil. Data analysis allowed to corroborate the most common clinical symptom and the frequent histological type in the literature. This neoplasm classically presents early symptoms and curative treatment, however the data analysis shows a high death rate and diagnosis of advanced disease. So, the endometrioid type, doesn´t have the best prognosis always and needs a better molecular analysis to optimize therapy,to reduce mortality.
