On univariate survival analysis, age (P<0.10), tumour size (P<0.0001), grade (P<0.05), lymph node involvement (P<0.05), hormone receptor status (P<0.01), albumin (P⩽0.001), loco-regional treatment (P<0.01) and systemic treatment (P<0.001) were significantly associated with overall survival. This evidence concerns the gene ALB and neoplasm.
