In Park et al.’s [13] examination of 1011 cases with lung cancer using the “preoperative prognostic nutritional index” [10 × serum albumin (g/dl) + 5 × total lymphocyte count (/nl) based on the preoperative laboratory data], higher rates of postoperative complications and mortality were identified in cases with low prognostic nutritional index scores. The gene discussed is ALB; the disease is lung carcinoma.
