Furthermore, the low expression levels of ADIPOQ (HR = 0.416, p < 0.01), IGF1 (HR = 0.458, p < 0.05), LEP (HR = 0.527, p < 0.05), NR3C1 (HR = 0.457, p < 0.05), and PPARG (HR = 0.491, p < 0.05) were notably related to the poorer BCSS of breast cancer patients with tumor pathological stages III–IV. The gene discussed is IGF1; the disease is neoplasm.
