Abstract:
Objective To analyze the curative effects,late phase reactions and their prognostic factors of nasopharyngeal carcinoma (NPC) treated with radiotherapy.Methods Retrospective analysis was made for 246 cases of NPC which were confirmed by pathological diagnosis and with complete follow-up data in the first affiliated hospital of Soochow university.Kaplan-Meier method was used for analysis of survival rate and the log rank method was used to compare the survival between groups.Cox regression was used for analysing the prognostic factors.Logistic regression was used for analysing the factors which affect the late phase reactions.Results The follow-up rate was 94.6％.The 1-year,3-year,5-year overall survival (OS) were 97.97％,81.82％,67.85％.The 1-year,3-year,5-year progression-free survival (PFS) were 83.33％,70.00％,39.29％ respectively.Age (x2=6.604,P=0.010),T stage (x2 =3.670,P=0.050),N stage (x2=19.658,P =0.001) and the clinical stage (x2 =4.626,P =0.031) were the prognostic factors for the OS.Cox multi-variate analysis showed that the independent prognostic factors for the OS were clinical stage and age.Logistic regression analysis showed that the independent prognostic factors for the late phase reactions were age and rehabilitation time.Conclusion The main factors for the long term survival of NPC patients after radiotherapy are early TNM stage and young age.Patients with younger age and longer rehabilitation time have lower incidence of late phase reactions.
