Detection of early recurrent nasopharyngeal carcinoma (NPC) is clinically challenging. Narrow-band imaging (NBI) is powerful in detecting early superficial lesions in the head and neck, although the utility of NBI in detecting nasopharyngeal cancer is still unknown.
We describe a case of a 51-year-old man with early recurrent NPC detected in subclinical stage by NBI coupled with conventional endoscopy. MRI revealed no obvious bulging or inward invasion over the nasopharynx. Because of superficial, localized recurrence, we performed laser nasopharyngectomy and his postoperation course was uneventful.
We demonstrated that postirradiated NPC in a patient with early recurrence was successfully detected by NBI coupled with conventional endoscopy. NBI endoscopy is a simple, convenient, and reliable tool, and adds additional value to detect local recurrence in the early phase. It may serve as an ideal tool in posttreatment surveillance in a patient with NPC.
早期复发性鼻咽癌（NPC）的检测具有临床挑战性。窄带成像（NBI）在检测头颈部早期浅表病变方面具有强大作用，尽管 NBI 在检测鼻咽癌中的效用尚不清楚。
我们描述了一例 51 岁男性病例，通过 NBI 联合常规内窥镜检查在亚临床阶段检测到早期复发性 NPC。MRI 显示鼻咽部无明显隆起或向内侵犯。由于病变位置较浅且局限，我们采用激光鼻咽切除术，患者术后恢复顺利。
我们证实，通过 NBI 联合常规内窥镜检查成功检测到接受过放疗的 NPC 患者的早期复发。NBI 内窥镜检查是一种简单、方便、可靠的工具，为早期发现局部复发增加了额外的价值。它可能成为 NPC 患者治疗后监测的理想工具。
