We conducted a systematic review and meta-analysis to investigate the effectiveness of moisturizers on acute radiation dermatitis (ARD) in breast cancer patients receiving radiotherapy (RT).PubMed, the Cochrane Library, CINAHL, and Ichushi-Web were searched for randomized controlled trials (RCTs) from April 2015 to March 2020. Assessments included type of intervention, cohort, outcomes, and quality of evidence. To evaluate the effect of moisturizer on ARD, we restricted analyses to studies comparing with standard skin care or no treatment. Outcomes were ARD severity and skin-related QOL (quality of life). Eligible studies were identified, and risk ratios and mean differences were extracted to compare outcome data.We screened 210 RCTs along with 14 studies included in a previous iteration of this analysis (2016), supplemented by a hand search (n = 9). Finally, we included 6 RCTs that investigated the effectiveness of standard type moisturizers in breast cancer patients receiving RT. Evidence (weak certainty) suggests that moisturizer use might reduce ≥ grade 3 ARD. QOL assessed by Skindex-16 improved with moisturizer use. Pain and pruritus measured by the visual analog scale (VAS) resulted in a smaller and nonsignificant difference in favor of moisturizer use. However, the certainty of the evidence was very weak in QOL.The proactive use of moisturizer may play a role in reducing ARD and improving skin-related QOL, although the certainty of the evidence was weak to very weak. Future high-quality RCTs should be initiated to strengthen these results.
