As regards the inflammatory implications in BC, it has been demonstrated that tumour cells highly express also IL-8, IL-1β and monocyte chemoattractant protein-1 (MCP-1), whose levels are associated with poor recurrence-free survival in patients with HER2(−) tumours [61] and, in general, with poorer prognosis [50, 62]. The gene discussed is CCL2; the disease is neoplasm.
