Abstract

Background: Radiation-induced oral mucositis (RIOM) is a major side-effect of (chemo)radiation (CRT) of patients with head and neck cancer (HNC). This study tries to establish a novel cryotherapy (CyT) method using a mouth care device (MCD; Cooral®, BrainCool AB, Lund, Sweden) to prevent RIOM.

Methods: Patients were non-randomly assigned to use the MCD after every radiotherapy session for 30-60 minutes. Subjects were asked to answer daily questionnaires assessing tolerability of the intervention. Mucositis was assessed at baseline, once weekly and at weeks 1/3/6 after CRT. The primary endpoint was patient tolerance, defined by the time the MCD was used and the patients' perception. Secondary outcomes were the degree (CTCAE v5.0) and duration of RIOM.

Results: Ten patients were eligible with a mean age of 62 years. Four patients received concurrent platinum-based CRT, whereas the others received radiotherapy alone. Overall, 214 CyT sessions were performed (73% of planned CyT sessions). The mean daily CyT duration was 48 minutes (range, 30-60 minutes). All patients reported cooling as comfortable. Nine completed the intervention, one terminated it early due to hypersalivation. No Grade 4 RIOM was observed. Grade 3 mucositis was observed in 4 and Grade 2 in 3 cases.

Conclusions: The Cooral System was well tolerated, with a duration of application that was acceptable for most patients. We concluded that the MCD can be safely used in patients undergoing CRT. A prospective phase II trial, assessing the efficacy in preventing RIOM, is planned.

在接受放射治疗(CooRay)的患者中使用Cooral口腔冷却装置进行冷冻治疗的可行性和患者报告的耐受性:一项试点研究。
背景:放射性口腔黏膜炎(RIOM)是头颈癌(HNC)患者化疗后的主要副作用。本研究试图建立一种使用口腔护理装置(MCD;Cooral®,BrainCool AB, Lund, Sweden)预防RIOM。方法:非随机分配患者在每次放疗后30-60分钟使用MCD。受试者被要求回答评估干预耐受性的每日问卷。在基线、每周一次和CRT后1/3/6周评估粘膜炎。主要终点是患者耐受性,由使用MCD的时间和患者的感知来定义。次要指标为RIOM程度(CTCAE 5.0)和持续时间。结果:10例患者符合条件,平均年龄62岁。4例患者同时接受铂基CRT,其余患者单独接受放疗。总体而言,进行了214次CyT治疗(占计划CyT治疗的73%)。平均每日CyT持续时间为48分钟(范围30-60分钟)。所有患者报告降温后感觉舒适。9人完成了干预,1人因唾液过多而提前终止。未见4级RIOM。3级黏膜炎4例,2级黏膜炎3例。结论:Cooral系统耐受性良好,应用时间对大多数患者是可接受的。我们的结论是,MCD可以安全地用于接受CRT的患者。计划进行一项前瞻性II期试验,评估预防RIOM的疗效。

期刊介绍: Translational Cancer Research (Transl Cancer Res TCR; Print ISSN: 2218-676X; Online ISSN 2219-6803; http://tcr.amegroups.com/) is an Open Access, peer-reviewed journal, indexed in Science Citation Index Expanded (SCIE). TCR publishes laboratory studies of novel therapeutic interventions as well as clinical trials which evaluate new treatment paradigms for cancer; results of novel research investigations which bridge the laboratory and clinical settings including risk assessment, cellular and molecular characterization, prevention, detection, diagnosis and treatment of human cancers with the overall goal of improving the clinical care of cancer patients. The focus of TCR is original, peer-reviewed, science-based research that successfully advances clinical medicine toward the goal of improving patients'' quality of life. The editors and an international advisory group of scientists and clinician-scientists as well as other experts will hold TCR articles to the high-quality standards. We accept Original Articles as well as Review Articles, Editorials and Brief Articles.
