[Breast Cancer: Immunohistochemistry And Prognosis At Gabriel Touré Teaching Hospital In Bamako-Mali]

Breast cancer is the second cancer of women in Mali. Immunohistochemistry is poorly performed in our African countries.

To describe the immunohistochemical aspect and determine the prognosis of breast cancer.

This is a retrospective descriptive study (March 2006-July 2016) in the General Surgery Department of Gabriel Toure University Hospital in Bamako, Mali. Immunohistochemistry was performed in all patients through a collaboration of our German partners.

We collected 98 patients (95 women and 3 men) with an average age of 40.04 ± 13.07 years. Twenty-two patients (22.44%) had a personal history of benign breast disease. In 16 patients (16.33%), we found a family breast cancer. The most common histological types were intra ductal carcinoma with 84 (85.72%) and invasive lobular carcinoma in 9 cases (9.18%). Immunohistochemistry found a predominance of triple negative with forty nine patients (50%) followed by Luminal A subtype with 26 cases (26.23%). According to the TNM classification, 44 patients (44.90%) were received at stage III. The median survival was 60 months in the group of patients who received hormone therapy versus 28 months for the group without hormone therapy (p = 0.007).

Immunohistochemistry is essential for the adequate management of breast cancer. Its realization has allowed us to improve the prognosis of hormone-dependent cancers.
