Nasopharyngeal carcinoma (NPC) is rare in young patients. The aim of this study was to provide an analysis of 42 patients under 20 years of age with locoregional disease treated in a single institution.
Forty-two NPC patients aged <or=20 years (median age 16 years) represented only 2.3% of all NPC cases treated in our department between 2000 and 2003. Of these patients, 14 were stage II, 21 stage III, and seven stage IV, as diagnosed according to the 1997 American Joint Committee on Cancer (AJCC) staging system. Seventeen patients received radiotherapy alone and 25 had cisplatin-based chemotherapy additionally. The radiation dose to the primary tumour and involved nodes was 64-74 Gy.
After a median follow-up of 60 months, the 5-year locoregional control, overall survival and disease-free survival rates were 87, 79 and 73%, respectively. More than 50% of the relapses (6/11) were distant metastases. Patients with N0-1 had a lower distant metastasis rate compared with patients with N2-3, and the TNM stage grouping was found to be a marginally important prognostic factor for disease-free survival. The addition of chemotherapy failed to be of therapeutic value. Acute and chronic toxicities were limited, consisting primarily of mucositis and xerostomia.
The outcome of the present series was excellent, and matched well with other publications. A high systemic failure remains a major obstacle to cure young NPC patients. More efforts should be made to improve both survival and quality of life.
鼻咽癌(NPC)在年轻患者中较为罕见。本研究旨在分析在单一机构治疗的 42 例局部区域疾病的 20 岁以下患者。
42 例 NPC 患者年龄<or=20 岁(中位年龄 16 岁),仅占 2000 年至 2003 年期间我科治疗的所有 NPC 病例的 2.3%。根据 1997 年美国癌症联合委员会(AJCC)分期系统诊断,其中 14 例为 II 期,21 例为 III 期,7 例为 IV 期。17 例患者接受单纯放疗,25 例患者接受顺铂为基础的化疗。原发肿瘤和受累淋巴结的放射剂量为 64-74Gy。
中位随访 60 个月后,5 年局部区域控制、总生存率和无病生存率分别为 87%、79%和 73%。超过 50%的复发(6/11)为远处转移。N0-1 患者的远处转移率低于 N2-3 患者,TNM 分期分组被发现是无病生存率的一个边缘重要预后因素。化疗的加入未能带来治疗价值。急性和慢性毒性反应有限,主要为粘膜炎和口干。
本系列的结果非常出色,与其他出版物相匹配。高全身失败率仍然是治愈年轻 NPC 患者的主要障碍。应努力提高生存质量。
