PGR and cancer: PR negativity in 63% of cases is comparable to data from Taucher S et al. [23] which showed PR negativity of 70%. HER2 receptors were found to be positive in 50% of the cases. Triple-negative cancers constituted 31% of cases, which is consistent with many studies showing a higher prevalence of triple-negative breast cancers in the Indian population compared to the Western population [24-26].
