BACKGROUND: The study aim was to evaluate the efficacy of wrapping oblate for prevention of everolimus-associated stomatitis in metastatic renal cell carcinoma (mRCC).
PATIENTS AND METHODS: Patients with mRCC prescribed everolimus after failure of vascular endothelial growth factor-tyrosine kinase inhibitor were enrolled. Patients were consecutively assigned to take everolimus covered with or without oblate. The primary end-points were the incidence of and time to grade 2 or more stomatitis. Additionally, we assessed whether grade 2 or more stomatitis that occurred in the non-oblate group could be prevented with crossover application of oblate.
RESULTS: This study included 79 patients [oblate group: 42(53%); non-oblate group: 37(47%)]. Thirty (38%) patients developed grade 2 or more stomatitis [incidence: oblate group, 31% (13/42); non-oblate group, 46% (17/37), p=0.245; median time to grade 2 or more stomatitis: oblate group, not reached; non-oblate group, 6.0 months, p=0.251]. Among 10 patients who developed grade 2 or more stomatitis in the non-oblate group and received oblate-covered everolimus, nine (90%) showed complete recovery or improved to grade 1, which persisted until discontinuation of everolimus.
CONCLUSION: Oblate-covered everolimus improved the incidence of and time to grade 2 or more stomatitis, although it was not statistically significantly different compared to the non-oblate group. Oblate wrapping prevented recurrence of grade 2 or more stomatitis in patients who took uncovered everolimus and developed significant stomatitis.
