Background:
Androgen receptors (ARs) are expressed in more than 70% of breast cancers (BCs) and have been implicated in BC pathogenesis. Some triple negative (TN)BC tumors express AR and may benefit from ARtargeted therapies. The aim of this study was to evaluate survival and the prevalence of AR expression and its correlation with other risk factors in triple negative BCs in women from Western Iran.
Materials And Methods:
In a retrospective study between 20092015, 41 patients with TNBC were referred to the Private Clinic of Oncology, Kermanshah city, Iran. ER, PR and ARpositive expression was defined as ≥10% nuclear staining and also HER2 (2+), FISH was performed. Nuclear staining was considered representative for Ki67 and P53. The mean followup for the patients was 25 months. In this time, 5 patients died and 4 lost to followup were censored from survival analysis.
Results:
The mean age at diagnosis was 46.9 years (range, 2471 years) and all patients were female. The OS rates for ARpositive and ARnegative patients were 90% and 85.1%, respectively, and the mean OS was 26.3 and 23.2 months. Therefore, there was no significant difference between the two groups (Hazard ratio: 0.580, 95% CI: 0.0863.893, P=0.575).
Conclusions:
In TNBC patients, evaluation of AR status may provide additional information on prognosis and treatment. The results of studies showed that the prevalence AR expression may differ in the world and probably ethnicity can be an influencing factor.
