Symptomatic treatment is insufficient for chemotherapy- or targeted therapy-induced oral mucositis (OM) pain, and benzydamine mouthwash is not commercially available in Japan. We evaluated the analgesic effects of an in-hospital preparation of 0.25% indomethacin spray (IMS) on anticancer drug-induced OM pain.
This single-arm prospective trial enrolled 20 patients (median age 62.0 years) with OM and numerical rating scale scores of ≥5 who were undergoing chemotherapy or targeted therapy in our hospital. Pain scores were recorded using a visual analog scale (VAS) before and 30 min after IMS administration. Pain relief (PR) scores were recorded at 15, 30, and 60 min after IMS administration; total PR after 60 min (TOTPAR ) was calculated, and the mean PR score after 3 days (PR ) was determined.
The median (interquartile range) OM grade of the participants was 2.0 (2.0-2.3). The VAS score decreased significantly at 30 min after IMS administration (p = .001). The median (interquartile range) TOTPAR and PR were 6.0 (3.8-7.3) and 2.0 (2.0-3.0), respectively.
IMS helped improve patients' quality of life. The risk of systemic adverse effects was low because of the low dose administered. IMS effectively relieved anticancer drug-induced OM pain and may be useful for immediate self-medication.
化疗或靶向治疗引起的口腔黏膜炎(OM)疼痛的对症治疗效果有限,且苄达明含漱液在日本并未上市。我们评估了院内自制 0.25%吲哚美辛喷雾剂(IMS)对癌症药物引起的 OM 疼痛的镇痛效果。
这项单臂前瞻性试验纳入了 20 名 OM 患者(中位年龄 62.0 岁),这些患者在我院接受化疗或靶向治疗,其 OM 疼痛的数字评分量表(NRS)评分≥5 分。在使用 IMS 前后通过视觉模拟量表(VAS)记录疼痛评分。在使用 IMS 后 15、30 和 60 分钟记录疼痛缓解(PR)评分;计算 60 分钟后的总 PR 评分(TOTPAR),并确定 3 天后的平均 PR 评分(PR)。
参与者的 OM 分级中位数(四分位距)为 2.0(2.0-2.3)。使用 IMS 后 30 分钟,VAS 评分显著下降(p=.001)。TOTPAR 和 PR 的中位数(四分位距)分别为 6.0(3.8-7.3)和 2.0(2.0-3.0)。
IMS 有助于提高患者的生活质量。由于给药剂量低,全身不良反应的风险较低。IMS 能有效缓解癌症药物引起的 OM 疼痛,可能有助于即时自我治疗。
