The presence of T4 stage (median overall survival—mOS: 23 vs. 30 months; HR = 1.92; p = 0.0093), advanced stage of disease (IV) according to the TNM classification (mOS: 24.5 vs. 29 months; HR = 1.89; p = 0.0174), the presence of moderate or severe malnutrition (mOS: 23 vs. 35 months; HR = 2.27; p = 0.0072), the occurrence of CWL (mOS: 18.5 vs. 27 months; HR = 1.91, p = 0.0142), and TT genotype of the TNFRSF1A gene (mOS: 14 vs. 26.5 months; HR = 2.98; p = 0.0012; Figure 2) were significantly related to a higher risk of death. This evidence concerns the gene TNFRSF1A and malnutrition.
