Abstract
BACKGROUND Chronic Graft-versus-Host Disease (cGVHD) can impact quality of life, especially in patients with oral involvement. Half of the patients with cGVHD do not respond to first-line therapy with corticosteroids and calcineurin inhibitors. Ruxolitinib is effective in steroid-refractory (SR)-cGVHD cases, but the long-term effects of ruxolitinib on the oral mucosa are unknown. OBJECTIVE(S): This study aims to assess the effect of ruxolitinib on the oral mucosa of SR-cGVHD patients with oral involvement. MATERIALS AND METHODS An observational longitudinal patient study was conducted in 53 patients with SR-cGVHD and oral involvement who were treated with ruxolitinib. The baseline condition of the oral mucosa was compared to its condition at 4 and 12 weeks after starting ruxolitinib. RESULTS The overall response was 81% (43/53), with a complete response in 53% (28/53) and partial response in 28% (15/53) after 12 weeks (p < 0.001). Men and patients concurrently using immunosuppressive therapy responded better than women (p = 0.005) and patients with ruxolitinib monotherapy (p = 0.02), respectively. At a longer follow-up (median 20 months), oral symptoms were comparable to the 12-week symptoms (p = 0.78), regardless of ruxolitinib use (p = 0.83). CONCLUSION Ruxolitinib treatment of SR-cGVHD patients with oral involvement was associated with a significant response of the oral manifestations at 12 weeks. CLINICAL RELEVANCE The oral mucosa of SR-cGVHD patients is likely to improve after 4 and 12 weeks of ruxolitinib treatment. Symptom severity at baseline does not affect the response of the oral mucosa.

Abstract
Aim of the study: Herein, this meta-analysis study evaluated the efficacy of palifermin after HSCT on the incidence and severity of OM or aGVHD in hematologic malignancy patients in randomized clinical trials (RCTs). Materials and methods: To compare the efficacy of palifermin on adverse events, OM and aGVHD compared with placebo, we searched databases of PubMed/Medline, Web of Science and Cochrane Library for RCTs based on a number of criteria. Results: There was no difference observed in the incidence of OM and aGVHD between two groups. The subgroup analysis didn't show significant differences in two groups for aGVHD grade 2-4 (odds ratio [OR] = 1.54, 95% confidence interval (CI): 0.70-3.39, p = 0.28), aGVHD grade 3-4 (OR = 0.97, 95% CI: 0.48-1.94, p = 0.92), OM grade 2-4 (OR = 0.76, 95% CI: 0.42-1.38, p = 0.37) and OM grade 3-4 (OR = 0.54, 95% CI: 0.25-1.15, p = 0.11], but erythema as an adverse effect in palifermin group was higher than placebo group (OR = 1.86, 95% CI: 1.10-3.15, p = 0.02]. Conclusions: This meta-analysis of six clinical trials found no statistically significant difference in OM and aGVHD grades in patients receiving 60 mug/kg/day dose of palifermin compared with those receiving a placebo. However, oral mucosal erythema was more prevalent among patients receiving palifermin than patients receiving a placebo.
