Among the lab preoperative clinical variables analysed, we noted significant differences on the incidence of lymphopenia (lymphocyte count <103/μl, OR = 1.842 [1.063–3.191], p = 0.029) and the albumin admission level (OR per g/dl = 0.507 [0.268–0.959], p = 0.037), establishing the critical point at albumin admission level ≤3.5g/dl (OR = 2.474 [1.316–4.643], p = 0.005). This evidence concerns the gene ALB and lymphopenia.
