The efficacy of neoadjuvant chemotherapy and adjuvant chemotherapy on stage IIb nasopharyngeal carcinoma(NPC) remains unclear. Conventional two-dimensional radiotherapy combined with concurrent chemotherapy can improve the overall survival, progression-free survival, recurrence-free survival, and distant metastasis-free survival of patients with stage IIb NPC. Intensity-modulated radiotherapy without concurrent chemotherapy also provides good outcomes for patients with stage IIb NPC. This article summarizes the features of stage IIb NPC and reviews the role of chemotherapy in this subgroup of NPC.
