HERNANDEZ-ALVAREZ, Consuelo; ROMO-AGUIRRE, Catalina y ORTIZ-DE ITURBIDE, Cecilia. Triple-negative breast cancer: frequency and characteristics at Hospital Ángeles Pedregal. Acta méd. Grupo Ángeles [online]. 2017, vol.15, n.4, pp.269-274. ISSN 1870-7203.
Background:
Breast cancer is the leading cause of death in women in Mexico; it is a heterogeneous disease that requires a multidisciplinary approach.
Objective:
To review the anatomopathological and immunohistochemical characteristics in triple-negative breast cancer patients described in the Mexican population and compare them with the sample reported from January 2009 to August 2015 at the Hospital Ángeles Pedregal.
Material and methods:
We conducted a cross-sectional, descriptive and retrospective study of patients with diagnosis of triple-negative breast cancer and mammography studies performed during the period from January 2009 through August 2015 at the Hospital Ángeles Pedregal.
Results:
We identified 3,290 breast tissue specimens, 600 (18.24%) with histopathologic diagnosis of breast cancer. Triple-negative breast cancer was reported in 58 cases (9.6%). Average age of diagnosis: 56 years; histological type: 80.13% infiltrating ductal carcinoma; average tumor size < 20 mm: 55.31%. Mammography, 32 cases: BIRADS 5 (6.25%), BIRADS 4 (75%), BIRADS 3 (18.75%).
Conclusions:
This study showed an average age of diagnosis of 56 years, suitable mammographic and histopathologic correlation, tumor size < 2 cm in half the cases, with characteristics similar to other studies reported in Mexican population.
