Abstract:
OBJECTIVETo investigate the treatment and prognosis for rN3 neck recurrence of nasopharyngeal carcinoma (NPC) after primary radiotherapy.
METHODSA total of 37 cases with rN3 neck recurrence after radiotherapy in NPC between October 2003 and August 2013 were retrospectively analyzed. Of them 19 cases presented with lymph node (LN) metastasis in supraclavicular fossa, 18 cases had metastasis LN > 6 cm, 10 cases received chemoradiotherapy, and 27 cases underwent neck dissection including modified radical neck dissection (MRND) for 9 cases, radical neck dissection (RND) for 18 cases. Six of 18 cases with RND underwent reconstructive surgery with pectoralis major flap, 12 cases received postoperative radiotherapy and 20 cases had postoperative adjuvant chemotherapy.
RESULTSEight patients had documented recurrence or residue, 17 patients developed distant metastases, one patient showed recurrence and distant metastasis. The 5-year overall survival rate and disease-free survival rate were 27.5% and 21.6% respectively, and the median survival time was 41 months. The survival rate in surgery group was significantly higher than that in chemoradiotherapy group, and the prognosis of patients with LN > 6 cm was better than that of patients with metastasis LN to supraclavicular fossa.
CONCLUSIONSPatients with rN3 NPC are prone to metastasis, and patients with supraclavicular fossa lymph node metastasis had poor prognosis. Surgery combined with chemoradiotherapy is an effective treatment for the patients without distant metastasis.
