e20504 Background: Painful oral mucositis is the most significant dose-limiting toxicity in head & neck cancer patients treated with conc. CT-RT protocol. The purpose of this study is to evaluate the efficacy of oral morphine gargles in reducing the severity of chemoradiation induced mucositis pain & thus, its impact on nutrition, quality of life & cost of supportive care, during the treatment period. Methods: 106 consecutive patients, recruited between May 2006 through Dec. 2007, with adv. head and neck cancers (54 oropharynx, 42 hypopharynx & 10 nasopharynx) were included in the study. All patients underwent treatment under conc. CT-RT (Inj.CDDP 40mg/m2 weekly, RT: 66–70gy/33–35# @200cgy/# delivered by 3D- CRT). Patients who had painful mucositis (RTOG Grade 3 or more) not controlled with magic mouthwash, Tab. Acetaminophen 500mg qds or Tab.Tramdol 50–100 mg tds were randomized into 2 groups: morphine group (MOP) -53 patients & Control group (CON) - 53 patients. Patients in both groups received adjusted doses of oral steroids based on the severity of oral mucositis. While CON group patients were given adjusted doses of tramadol, MOP group patients were assigned to 15ml of 2% morphine gargles administered every 4th hourly. Patients were instructed not to swallow the rinses and to hold the solution in the mouth for 3mins duration. All patients underwent weekly recording of (1) response to pain rated on VAS (2) weight (3) morphine systemic side-effects (4) QOL Questionnaire. Mann-Whitney test and ’T’ Test are used for statistical analysis of the data. Results: Patients in the MOP group had significant lower pain intensity scores, better QOL scores & less weight loss compared to patients in the CON group. The duration of the severe pain was atleast 1 week shorter in the MOP group. Systemic side-effects secondary (nausea, vomiting, constipation) to opiod use were significantly lower in the MOP group. The Cost of supportive care for pain management was less in the MOP group, with greater compliance for the treatment. Conclusions: Morphine gargles, in our experience, is an effective approach for pain relief in patients with CT-RT induced acute mucositis in head and neck cancers thus leading to better nutrition & compliance in the treatment. No significant financial relationships to disclose.

5523 Background: This study evaluated the effect of RK-0202, administered as an oral rinse, on the incidence of severe oral mucositis in patients being treated with of radiation therapy (RT) for tumors of the head and neck. Methods: This was a prospective, randomized, placebo-controlled, double-blind study that compared the effect of 2 concentrations of RK-0202 with placebo on the incidence of severe oral mucositis at a cumulative RT dose of 60 Gy in 110 subjects. Twenty-seven subjects received RK-0202 5%, 38 received RK-0202 10%, 29 received placebo and 16 received standard of care. Subjects began dosing just prior to RT and continued dosing six times daily throughout RT. Oral mucositis was assessed twice weekly throughout RT by trained oral evaluators. Results: The higher dose of RK-0202 (10%) successfully attenuated severe oral mucositis as measured by WHO or NCI-CTC v.3 criteria. The incidence of WHO grade 3 or 4 oral mucositis by a cumulative RT dose of 60 Gy was 35% in the RK-0202 group vs. 54% in the placebo group (p = NS). By 50 Gy the incidences in the RK-0202 and placebo groups were 25% and 54%, respectively (p = 0.053). Similarly, the incidence of NCI grade 3 or 4 oral mucositis by 60 Gy was 64% in the RK-0202 cohort vs. 92% for subjects being treated with placebo (p = 0.005). Subjects treated with RK-0202 required less feeding tube placement compared to placebo recipients (3% vs. 22%, p = 0.037) and less opiate analgesia. The median percent of time on opiates was 6% on RK-0202 vs. 21% on placebo. The overall incidence of serious adverse events was significantly lower in subjects treated with RK-0202 (8% vs. 31%, p = 0.024). In general, there was no benefit noted among subjects who received RK-0202 as a 5% solution. Conclusions: RK-0202 significantly reduced the incidence of severe mucositis in subjects treated with radiotherapy for head and neck cancer and was not associated with significant adverse events.
