For instance, a nationwide study consisting of 33,917 patients who underwent distal gastrectomy for treating gastric cancer revealed that levels of blood urea nitrogen >20 mg/dl, creatinine >1.2 mg/dl, albumin <3.8 mg/dl, platelets <12× 104/ml, white blood cells >9000/ml were associated with both morbidity and mortality [28]. The gene discussed is ALB; the disease is gastric cancer.
