TRIPLE NEGATIVE BREAST CANCER, EXPERIENCE OF MILITARY HOSPITAL RABAT: ABOUT 52 CASES

Objective: to review the epidemiological, clinical, anatomopathological, biological, therapeutic and prognostic characteristics of this histo-prognostic subgroup, namely triple-negative breast cancer

Material and Method: Our work consists of a retrospective study carried out at the military hospital of instruction Med v rabat between January 2010 and December 2017 on 52 cases of invasive breast carcinoma with a triple negative phenotype.

Result:

From an epidemiological point of view: a peak in frequency was noted between 45 and 50 years old, and 48.1% of patients still in genital activity.

On the anatomo-pathological level: invasive ductal carcinoma is the most predominant type representing 68.3% of cases with an average tumor size of 30mm. Histopronostic grades II and III each represent 43.2% and 56.8% of cases.

Therapeutically: more than 42.3% received conservative treatment and 57.7% underwent radical surgery of the Pateytype.Adjuvant systemic chemotherapy was given in 86.5% of cases and 5.8% received neoadjuvant chemotherapy

On the evolutionary level, 17.3% or 9 cases developed systemic metastases with predilection for the lungs.

Conclusion: Despite advances in treatments and the emergence of targeted therapies, breast cancer remains the leading cause of death in women. Current clinical and histological classifications do not fully establish the prognostic and predictive parameters of response to treatment.
