Prospective evaluation of oral mucositis in solid tumor patients undergoing chemotherapy and its clinical implication

Abstract

e20650 Background: Oral mucositis (OM) induced by chemotherapy is a troublesome and debilitating adverse effect in solid tumor patients. OM might influence the complicated aspects such as the poor oral intake and malnutrition over just oral symptom. Therefore we prospectively evaluated the actual incidence of OM and its clinical significance in solid tumor patients. Methods: From October 16, 2007 to September 3, 2008, we consecutively enrolled 344 patients with solid tumor who initiated new chemotherapy. Each patient was prospectively evaluated for two cycles. The data were collected from physician-to-patient interview. And patients’ diary for OM symptom was used as patient-reported measurement. The visual analog scale (VAS) was used to quantify the degree of adverse effects (VAS: 0 point = no symptoms, 4 point = the worst symptom) and FACT-G was used for assessment of the quality of life (QOL). Results: Finally, 322 patients were analyzed. The median age was 51. Breast cancer was the most common (51%). And, stage IV was 137 (43%). OM was 28% per each cycle and 45% per patient during two cycles. Patient-reported OM symptom had peak in one week and was recovered in 9.14±6.77 days. Oral dryness was the most prevalent symptom out of symptoms related with OM such as oral pain, poor oral intake, dysphagia, oral bleeding, scalloping of tongue and ulceration (VAS score 1≤; 47%, 27%, 39%, 15%, 7%, 14%, 13%, respectively). In QOL measured by FACT-G, physical well-being and emotional well-being were significantly dropped in OM-occurred group than in no-OM group (19.09±6.48 vs 22.47±5.95, p<0.001; 16.74±4.10 vs 17.97±3.38, P<0.001, respectively). In addition, higher VAS score for other adverse effects was showed in OM-occurred group than in no-OM group (activity, nausea, vomiting, fever, myalgia and nervous system; p=0.0038, p<0.0001, p=0.0007, p=0.0062, p<0.0001, p<0.0001, respectively). Conclusions: Forty five percent of patients with solid tumor experience OM during 2 cycles of chemotherapy. In case of patients with OM, QOL is worse and the other adverse effects are more prevalent. OM could be an indicator of QOL and other adverse effects during chemotherapy. No significant financial relationships to disclose.
