RESUMO
BACKGROUND: Oral mucositis is a frequent complication, but is poorly studied among patients with solid tumors. The purpose of this study is to clarify the incidence rate of oral mucositis in Japanese breast cancer patients receiving anthracycline-based chemotherapy(FEC100). METHODS: From June 2007 to July 2008, 61 breast cancer patients eligible for this study received anthracycline-based chemotherapy(FEC100: 5-FU 500mg/m / / 2, epirubicin 100 mg/m2, cyclophosphamide 500 mg/m2)at National Kyushu Cancer Center and Iwate Medical University Hospital. The incidence rate and grade of oral mucositis were evaluated in these patients. RESULTS: The cumulative incidence of oral mucositis was about 50%. Episodes of oral mucositis were more common during courses with febrile neutropenia than during courses without it(75. 0% vs 44. 9%, p=0. 12). The reduction of oral mucositis was only 13. 6% after administering the steroidal ointment and/or mouthwash, including sodium azulene sulfonate. CONCLUSIONS: New methods are needed to prevent and treat oral mucositis in patients receiving anthracycline- based chemotherapy(FEC100).
