Advances in radiation delivery, imaging techniques, and chemotherapy have significantly improved treatment options for non-metastatic nasopharyngeal cancers (NPC). However, their impact on the practice in the United Kingdom (UK), where this tumour is rare, is unknown. This study examined the current attitudes of UK head and neck oncologists to the treatment of NPC.
UK head and neck oncologists representing 19/23 cancer networks were sent an invitation email with a personalised link to a web-based survey designed to identify the influence of tumour and nodal staging on current NPC management practices.
26/42 (61%) of clinicians responded. Induction chemotherapy followed by concomitant chemoradiation was the treatment of choice for Stage III (69%) and IVa/b (96%), with cisplatin and 5-fluorouracil combination being the most commonly used induction chemotherapy regimen (88%). 16 centres (61%) used a geometric approach, adding variable margins of 0-10 mm to the gross tumour volume to define their therapeutic dose clinical target volume. 54% of respondents used 3 radiotherapy (RT) prescription doses to treat NPC. Retropharyngeal nodal region irradiation policy was inconsistent, with nearly one-quarter treating the entire group to a radical dose.
Significant heterogeneity currently exists in the RT practice of NPC in the UK. A consensus regarding the optimal curative, function-sparing treatment paradigm for NPC is necessary to ensure cancer survivors have satisfactory long-term health-related quality of life. Advances in knowledge: This is the first study to highlight the significant variation in RT practice of NPC in the UK.
放射治疗、成像技术和化疗方面的进展显著改善了非转移性鼻咽癌(NPC)的治疗选择。然而,在英国这种肿瘤较为罕见,这些进展对英国临床实践的影响尚不清楚。本研究调查了英国头颈肿瘤学家目前对NPC治疗的态度。
向代表英国23个癌症网络中19个网络的头颈肿瘤学家发送一封带有个性化链接的邀请电子邮件,该链接指向一项基于网络的调查,旨在确定肿瘤和淋巴结分期对当前NPC管理实践的影响。
42名临床医生中有26名(61%)做出了回应。诱导化疗后同步放化疗是III期(69%)和IVa/b期(96%)的首选治疗方法,顺铂和5-氟尿嘧啶联合方案是最常用的诱导化疗方案(88%)。16个中心(61%)采用几何方法,在大体肿瘤体积上增加0-10毫米的可变边界来确定其治疗剂量临床靶体积。54%的受访者使用3种放射治疗(RT)处方剂量来治疗NPC。咽后淋巴结区域的照射策略不一致,近四分之一的医生对整个组给予根治性剂量照射。
目前英国NPC的放射治疗实践存在显著异质性。有必要就NPC的最佳根治性、保留功能的治疗模式达成共识,以确保癌症幸存者拥有令人满意的长期健康相关生活质量。知识进展:这是第一项强调英国NPC放射治疗实践存在显著差异的研究。
