Therefore, neutrophils and platelets were not included in the multifactorial regression, which finally showed that the targeted therapy and T stage were independent factors of prognosis (p < 0.05) (Table 3).The prediction model equation for the efficacy of IC sequential CCRT combined with targeted therapy in EGFR-positive NPC patients was obtained as Y = 0.3199 + 2.494X1 + − 0.7547 × 2 (Y = efficacy, X1 = targeted therapy, X2 = T stage). The gene discussed is EGFR; the disease is nasopharyngeal carcinoma.
