Moreover, CIA was associated with favorable disease-free survival (OR = 0.595, 95% CI = 0.537 to 0.658, p < 0.001) and overall survival (OR = 0.547, 95% CI = 0.454-0.660, <i>p</i> < 0.001) in premenopausal patients with breast cancer.<h4>Conclusion</h4>Age, HR status, ER status, PR status, tamoxifen administration, and chemotherapeutic regimen can be considered independent factors to predict the occurrence of CIA. Here, PGR is linked to breast carcinoma.
