Background And Objective:
The prognosis of esthesioneuroblastoma (ENB) patients is poor. This study was to analyze prognostic factors and explore a rational treatment for ENB.
Methods:
Clinical data of 53 ENB patients, treated at Sun Yat-sen University Cancer Center from 1980 to 2003, were analyzed retrospectively. The correlation of prognostic factors to clinical features and treatment approaches were analyzed using the Kaplan-Meier method. Efficacy of different treatment modalities was compared.
Results:
The five-year overall survival (OS) was 41% of all ENB patients. The five-year OS of the surgery group, radiotherapy group, chemotherapy group, surgery combined with radiotherapy and (or) chemotherapy group, chemoradiotherapy were 42%, 38%, 0, 56%, 0, respectively, which were statistically significant (p<0.05). The five-year OS of Kadish stage A, B, C patients were 100%, 37%, 31%, respectively, which were statistically significant among these three subgroups which (p<0.05). The recurrence rate over the entire period was 51%. The five-year OS of the recurrence group and recurrence-free group were 42% and 48%, respectively, without significant differences (p>0.05).
Conclusions:
ENB is a malignant tumor with high rates of locoregional recurrence and distant metastasis. Surgery-based multimodality is a relatively reasonable method. The prognosis of ENB is associated with the clinical stage and treatment modalities.
