Context: Chemoresistance is a major issue in patients with locally advanced oral squamous cell carcinoma (OSCC). In this study, we evaluated the effectiveness of melatonin in conjunction with neoadjuvant chemotherapy (NC) on hypoxia-inducible factor-1? (HIF-1?) expression and clinical response in locally advanced OSCC patients. Aims: To study the effects of melatonin on HIF-1? expression and its effect on the clinical response of patients with locally advanced OSCC. Settings and Design: A randomized controlled trial was conducted, wherein patients were recruited from several hospitals in Jakarta, Indonesia. Patients were randomized into two groups using computerized block randomization. Subjects and Methods: Both groups were given NC, with treatment group receiving melatonin. Outcomes measured in this study were HIF-1? expression from tissue samples and clinical response based on the RECIST 1.1 criteria. Twenty-five patients completed the study protocol and were included in the data analysis. Statistical Analysis Used: Shapiro-Wilk test was used to test the data normality. For data with normal distribution, we conducted an independent t-test to compare between the two groups. Data with abnormal distribution were analyzed using Mann-Whitney U-test. The mean difference between the two groups was analyzed using Shapiro-Wilk normality test. Results: Our study showed a significant decrease in HIF-1? expression in the melatonin group compared to the placebo group (P < 0.05, relative risk 3.08). However, the degree of reduction of HIF-1? expression in the melatonin group did not differ significantly (P = 0.301). Conclusions: Our study showed that melatonin administered at 20 mg/day could reduce the expression of HIF-1? and residual tumor percentage, but did not affect the clinical response in OSCC patients. ? 2021 Annual Reviews Inc..
