Background
To explore the efficacy and patterns of treatment failure of radical radiotherapy in newly diagnosed oligo-metastatic nasopharyngeal carcinoma patients.
Methods
We included 39 newly diagnosed oligo-metastatic nasopharyngeal carcinoma patients who received radical radiotherapy and chemotherapy in Zhejiang Cancer Hospital. Treatment and prognosis information were collected. The Kaplan–Meier methods and Cox proportional hazards models were used to calculate survival rates and analyze prognostic factors.
Results
After a median follow-up time of 38 months, the 1-, 3-, and 5-year overall survival rates were 97, 70, and 57.9%, while the 1-, 3-, and 5-year progression-free survival rates were 87, 59, and 50.9%, respectively. Age, numbers of metastases lesions, cycles, and schemes of chemotherapy were independent prognostic factors of the overall survival. Patients with no more than three metastasis lesions had a higher survival rate than those with ≥ 3 metastatic lesions (P = 0.023). More than four cycles chemotherapy provide a higher survival rate than less than four cycles. Chemotherapy including docetaxel had a significantly survival advantages (P = 0.041).
Conclusion
Radical radiotherapy is important for newly diagnosed oligo-metastatic nasopharyngeal carcinoma patients, which can still achieve long-term survival after chemo-radiotherapy.
