Oral morphine gargles: A cost effective approach for pain relief in patients with chemoradiation induced acute oral mucositis in head and neck cancers
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.
