There was no significant association between IGF-1R mRNA expression and patients' age (p = 0.115), tumour size (p = 0.7417), grade (p = 0.1084), vascular invasion (p = 0.5879), ER status (p = 0.544), the presence of DCIS (p = 0.2966), lymph node status (p = 0.9412) or tumour stage (p = 0.0608–0.943). The gene discussed is IGF1R; the disease is neoplasm.
