The acute toxicities, prognosis, and potential predictors were analyzed. Then, a nomogram for PFS was established, and the performance of nomogram was compared with the performance of TNM system.Results: A total of 214 elderly patients (214/1981, 10.8%) were involved. Patients of Stage III and IV accounted for 73.4%. The 3-year, 5-year PFS and OS were 77.9%, 66.3%, 79.3% and 66.8%, respectively. Elder patients had a worse prognosis (P=0.002). The main cause of death remained in recurrence and metastasis; few died from comorbidities, and some died from nutrition status and psychological condition. Age (HR=1.10, 95% CI=1.05– 1.15, P< 0.001), ALB level (HR=0.93, 95% CI=0.88– 0.99, P=0.019), and T stage (HR=1.85, 95% CI=1.10– 3.13, P=0.022) were critical for PFS, but chemotherapy or comorbidities were not. Acute toxicities were mainly at or under grade II. N stage (OR=2.50, 95% CI=1.28– 4.88, P=0.007) and chemotherapy (OR=6.01, 95% CI=3.11– 11.63, P< 0.001) were risk factors for hematological toxicity; while age (OR=0.59, 95% CI=0.37– 0.92, P=0.020) and chemotherapy (OR=225.14, 95% CI=61.91– 818.64, P< 0.001) influenced emesis; ALB (OR=1.11, 95% CI=1.04– 1.19, P=0.002) affected mucositis. Comorbidities were not influential in acute toxicities. The nomogram for PFS (C-index=0.682, 95% CI=0.617– 0.747) performed better than the TNM system (C-index=0.604, 95% CI=0.532– 0.674, P< 0.001).Conclusion: Elderly NPC patients sustained poor prognosis. The easily applied nomogram is hopeful to benefit the clinical decision-making.Keywords: cancer, geriatric, survival, outcome, side effect, model |
