ALB and nasopharyngeal carcinoma: Stratification analyses indicated that the percentages of DM in the patients with NPC at UICC/AJCC T4, N2-3, higher UICC/AJCC stages, lower serum ALB or higher SF levels were significantly higher than those with lower UICC/AJCC T, lower N or UICC/AJCC stages, higher serum ALB or lower SF in this population (P = 0.012, P < 0.001, P < 0.001, P = 0.006 and P = 0.018, respectively, Table 1).
