RESUMEN
BACKGROUND: Everolimus is a mammalian target of rapamycin inhibitor used in the treatment of multiple tumor types, and its most common toxicity, stomatitis, can affect patient quality of life. Recent studies in breast cancer have supported the efficacy of steroid mouthwash for the prevention of everolimus-associated stomatitis. However, a few studies have been reported to date, and none have examined this effect in other tumor types. METHODS: This single-arm phase 2 study was designed to evaluate the efficacy of steroid-containing mouthwash for the prevention of stomatitis in patients with multiple tumor types receiving everolimus. The primary outcome was incidence of grade ≥ 2 stomatitis at 8 weeks of everolimus with steroid-containing mouthwash prophylaxis. We also assessed the stability of steroid-containing mouthwash components. RESULTS: Twenty-nine patients were evaluated, of which 76% had breast cancer and 24% had neuroendocrine tumors originating in the lung, gastrointestinal tract, pancreas, or of unknown primary origin. Grade ≥ 2 stomatitis incidence at 8 weeks was 28.1% (90% CI 16.2-46.1); the higher confidence limit exceeded the prespecified threshold of 30%. No patients developed grade ≥ 3 stomatitis. Most stomatitis occurred behind the oral cavity, with no lesions observed on the lips or floor of the mouth. CONCLUSIONS: Our findings did not support a prophylactic effect of steroid-containing mouthwash on everolimus-associated stomatitis. Given the needs of prevention of everolimus-associated stomatitis in various tumor types, further studies in a larger population using a randomized controlled trial design are, therefore, required to confirm the efficacy of steroid-containing mouthwash.

BACKGROUND/AIM: We investigated whether measuring the excretion of each acute kidney injury (AKI) biomarker after cisplatin (CDDP) administration is useful for predicting AKI and evaluated the most appropriate AKI marker in patients treated with CDDP. PATIENTS AND METHODS: We measured NAG, Kim-1, and NGAL in urinary samples of 40 cancer patients treated with chemotherapy on day 1 (before chemotherapy), day 2, and day 5 after treatment; serum creatinine (sCr) was compared on days 7 and 28 after CDDP administration vs. baseline. RESULTS: NAG, Kim-1, and NGAL excretion (creatinine corrected) were not significantly elevated 5 days after receiving chemotherapy in the non-CDDP chemotherapy group. Conversely, all markers were significantly higher 5 days after receiving chemotherapy in the CDDP group when compared to baseline. CONCLUSION: Urinary NAG, Kim-1, and NGAL can detect renal injury more sensitively than sCr.
