AB OBJECTIVE To evaluate the results and complications associated with nasopharyngeal carcinoma (NPC) treated with combined external-beam radiotherapy (EBR) and intracavitary brachytherapy (IB) using a new-type applicator.METHODS Eighty patients with untreated NPC were divided into two groups based on therapy methods. An experimental group was treated with EBR plus IB and a control group was treated only with EBR. IB was given to the patients of the experimental group when the external radiotherapy dose amounted to more than 60~65 Gy. The total dose of IB was 6~20 Gy and the total dose of EBR of the control group was 70~75 Gy.RESULTS Follow-up was conducted for 97.5% of the patients with results as follows: the overall response rates (ORR) for the experimental and the control groups were 92.5% and 75.3% respectively (P<0.05); the 3 and 5-year survival rates for the experimental group were 87.5% and 74.2% and for the control group, 65.0% and 55.6% (P<0.05); for the experimental group, the 3 and 5-year disease-free survival rates were 72.5% and 64.5% and for the control group, 60.0% and 52.8% (P>0.05). Some complications following radiotherapy showed a significant difference.CONCLUSION External irradiation plus intracavitary brachytherapy using a new-type applicator may improve the ORR and survival rates, reduce radiation complications and increase the quality of life.
