EPIDEMIOLOGIC PROFILE OF MEN HOSPITALIZED FOR BREAST CANCER IN BRAZIL

Introdução

Breast cancer is the most common type of cancer among women worldwide and in Brazil, after non-melanoma skin cancer. Breast cancer can also commit men, although rare, representing 1% of the total notifications of the disease. Due the rarity of this pathology, little is known about the etiology of male breast cancer, but some risk factors such as advanced age, hormonal imbalance and family history had been pointed out.

Objetivos

This study’s objective was to understand the epidemiologic profile of the men hospitalized due breast cancer in Brazil in the last five years.

Métodos

This is a descriptive study of secondary data, which was gathered by using the Informatics Department of the Brazilian Health System, and it corresponds to the cases registered from January of 2016 to December of 2020. The data of interest were those related to the total number of admissions, age range, ethnicity, mortality rate, average amount spent with each hospitalization.

Resultados

There were 3.501 (100%) admissions in Brazil due male breast cancer. In the southeast, there were 1.439 (41,1%) hospitalizations, being the part of the country with most hospitalized men. Followed by this region, comes the Northeast (26,7%), the South (18,1%), the Midwest (8,3%) and the North (5,7%). The year with more notifications was 2019, with a number of 832 hospitalizations (23,7%). The other years under review don’t show significant changes in the number of admissions. The predominant age group was between 60 to 69 years old (26,5%), followed by 50-59 (21,5%), 70-79 (19,9%) and 40-49 years old (13,4%; Fig. 1). Regarding ethnicity, white and brown men had similar notification, 1.326 (37,8%) and 1.248 (35,6%) respectively. The remaining percentage is for not registered (20,1%), black (5,0%), yellow (1,4%) and indigenous (0,02%; Fig. 2). The mean length of hospital stay for men with breast cancer was 4.3 days, ranging from 3.0 to 5.5 across the regions. The mortality rate was 9,40% in Brazil. Regarding the regions, Northeast showed the highest mortality rate, 14,50%. The average amount spent on each hospitalization was R$ 1.917,70 (USD 354,74, approximately).

Conclusões

In Brazil, the mortality rate of male breast cancer is higher than the mortality rate of female breast cancer, which is 8,44%. Therefore, the prognosis for male and female breast cancer is similar, but the overall survival rates are lower for males due to older age and advanced stage in diagnosis. Patients and health providers should pay attention about the existence of breast cancer in men and it’s known risks factors. Also, at last, many patients receiving hormonal therapy as treatment for other disease (eg., prostate cancer) should be aware of it’s side effect of developing male breast cancer.
