Oral mucositis refers to erythematous and ulcerative lesions of oral mucosa during chemo/radiotherapy. Treatment modalities were directed towards reduction in severity of oral mucositis. Zinc plays an important role to retard oxidative processes and is considered as the critical component in wound healing. To compare the efficacy of zinc alone with improvised zinc preparation in reducing the severity of oral mucositis. Improvised zinc was a combination of zinc oxide, amla, tulsi and curcumin at 1% therapeutic concentrations. Seventy-five subjects undergoing chemo/radiotherapy were randomly divided into three groups: Group A (25 subjects) had received topical 5% zinc oxide paste trice daily application after food for entire treatment period, initiated 2 d prior to radiotherapy. Group B (25) received improvised zinc preparations (1%) and instructed to apply same as group A. Group C (25) received standard treatment offered by cancer hospital. All the groups were assessed for oral mucositis using WHO grading system at 7th, 14th, 21st, 28th, 35th day by the oncologist and results were tabulated for statistical analysis. Severity of oral mucositis reduced in zinc and improvised zinc group (p=0.096) when compared with controls with significant p value (0.037). Comparison of improvised zinc preparation (1%) group with only zinc group revealed that severity of overall mucositis though was not significant, was less in improvised zinc group with p value (0.029, 0.013) at 28 and 35 d respectively. Improvised zinc administration during radiation therapy was beneficial in reduction of oral mucositis during cancer treatment.
口腔黏膜炎是指化疗/放疗期间口腔黏膜的红斑和溃疡病变。治疗方法旨在减轻口腔黏膜炎的严重程度。锌在减缓氧化过程中起着重要作用,被认为是伤口愈合的关键组成部分。比较单独使用锌与改良锌制剂在减轻口腔黏膜炎严重程度方面的疗效。改良锌是氧化锌、印度醋栗、圣罗勒和姜黄的混合物,浓度为 1%。75 名接受化疗/放疗的患者被随机分为三组:A 组(25 名)在放疗前 2 天开始,每天三餐后用 5%氧化锌软膏局部涂抹 3 次,持续整个治疗期;B 组(25 名)接受改良锌制剂(1%),并按 A 组的方法使用;C 组(25 名)接受癌症医院提供的标准治疗。所有患者均由肿瘤学家在第 7、14、21、28、35 天使用世界卫生组织(WHO)分级系统评估口腔黏膜炎,并进行统计学分析。与对照组相比,锌组和改良锌组的口腔黏膜炎严重程度均有所减轻(p=0.096),且差异具有统计学意义(p=0.037)。改良锌制剂(1%)组与单纯锌组比较,虽然总体黏膜炎的严重程度无显著差异,但改良锌组在 28 天和 35 天的 p 值分别为(0.029、0.013),表明改良锌组的口腔黏膜炎严重程度较轻。放疗期间给予改良锌制剂有利于减轻癌症治疗期间的口腔黏膜炎。
