| Popis: | The purpose of this study was to investigate the prophylactic irradiation volume to neck drainage areas for patients with N0 classification nasopharyngeal carcinoma (NPC) treated by intensity-modulated radiotherapy (IMRT).From January 2003 to October 2008, 270 patients with N0 classification (American Joint Committee on Cancer [AJCC] 2002 staging system) NPC who had undergone IMRT were retrospectively analyzed. Among all the patients, 171 patients received prophylactic upper-neck irradiation, and 99 patients received prophylactic whole-neck irradiation.At a median follow-up of 65.1 months (range, 4-106 months). The 5-year overall survival (OS), nodal recurrence-free survival (NRFS), and distant metastasis-free survival (DMFS) rates of the upper neck group and the whole neck group were 93.6% vs 90.9% (p = .553), 99.4% vs 99.0% (p = .278), and 98.8% vs 94.9% (p = .128), respectively. A total of 3 neck recurrences were found, including 2 from the whole neck group and 1 from the upper neck group. The latter (0.6%) was an out-of-field recurrence.Prophylactic irradiation to the upper neck (levels II, III, and VA) may be feasible for patients with neck lymph node-negative NPC. |
