| Abstract:: |
| Objective To investigate the post-irradiation neck fibrosis in patients with nasopharyngeal carcinoma and its related factors. Methods A total of 267 patients received conventional fractionated radiotherapy with D_T50-72 Gy on the neck a half year to 10 years ago were observed for the changes of cervical shape and functions. Results Different degrees of post-irradiation neck fibrosis were seen in all patients. The rate of heavy degree of neck radiation fibrosis was 24.34%,and it was 2.74% when received preventive dose on the neck. There was a very significant difference between patients who received late course of tangential irradiation on the neck and those who didn't receive (P=0.0001).The incidence of post-irradiation neck fibrosis didn't increase when patients received radiotherapy combined with chemotherapy(P=0.2678).The function of cervical muscles turned weak in patients received radiotherapy delivered by 6 MV accelerator in late course of tangential irradiation, whereas skin damage was severer in patients treated with 60Coγ-rays. Conclusion The incidence of heavy degree of post-irradiation neck fibrosis is high,and is related closely to late course of tangential irradiation. We should avoid adopting this sort of irradiation on the neck. |
