摘要

为了确定在2012年至2012年间,IMRT在2012年和2016年对847例NPC治疗的847例NPC治疗的847例患者的DATA中,在强度调节放疗(IMRT)ERA中,非转移性鼻咽癌(NPC)的失败模式和预后因素。分析了生存预后,失败模式和预后因素。局部5年的无局部无复发生存,无淋巴结复发生存,无转移的生存,无疾病的生存率和整体存活率分别为94.3%,95.3%,84.8%,76.5%和85.7%。局部主要复发位点是鼻咽(91.5%,43/47)和颅底(68.1%,32/47); 39名患者患有场地失败,4例出现了边际失败,四名患者发生了场外故障。 IIB级(62.2%,23/37)是最常见的区域复发部位,其次是IIA(35.1%,13/37)和咽后脑区域(32.4%,12/37); 35例仅发生场地故障,一个案件仅出现场外故障,而一个案件均出现了场外和外场失败。 TNM阶段是预测预测的最重要因素。 402(47.5%)患者患有3级或4级的急性不良事件;白细胞减少症(31.5%)和粘膜炎(26.7%)分别是最常见的血液学和非血液学事件。晚期并发症是轻微或中等的损害;静态(647/847,76.4%)和听力障碍(422/847,49.8%)仍然是最麻烦的。接受IMRT治疗的NPC患者获得了令人满意的生存结果。关键故障模式是遥远的转移。局部区域故障的主要模式是场地故障。应研究使用远处转移和优化放射治疗靶标的高风险患者。

Abstract

To identify the failure patterns and prognostic factors of nonmetastatic nasopharyngeal carcinoma (NPC) in the intensity-modulated radiotherapy (IMRT) era.Data on 847 patients with newly diagnosed, non-disseminated NPC treated by IMRT between 2012 and 2016 were retrospectively reviewed. Survival outcome, failure patterns and prognosis factors were analyzed.The 5-year local relapse-free survival, nodal relapse-free survival, distant metastasis-free survival, disease-free survival, and overall survival rates were 94.3%, 95.3%, 84.8%, 76.5% and 85.7%, respectively. The major local recurrence sites were the nasopharynx (91.5%, 43/47) and skull base (68.1%, 32/47); 39 patients had in-field failures, four had marginal failures, and four had out-field failures. Level IIb (62.2%, 23/37) was the most frequent regional recurrence site, followed by IIa (35.1%, 13/37) and retropharyngeal region (32.4%, 12/37); 35 cases had in-field failure alone, one had out-field failure alone, and one had both in- and out-field failure. TNM stage was the most significant factor for prognosis prediction. 402 (47.5%) patients had acute adverse events of grade 3 or 4; leukopenia (31.5%) and mucositis (26.7%) was the most common hematological and non-hematological event, respectively. Late complications were slight or moderate damages; xerostomia (647/847, 76.4%) and hearing impairment (422/847, 49.8%) remained the most troublesome.NPC patients treated with IMRT obtained satisfactory survival outcomes. The key failure pattern was distant metastasis. The main pattern of local-regional failure was in-field failure. Screening high risk patients with distant metastases and optimizing radiotherapy targets should be studied.
