Brief summary

Oral mucositis is a significant and common toxicity experienced by patients who receive high-dose chemotherapy as a preparatory regimen for a hematopoietic cell transplant (HCT). Furthermore, oral mucositis has been reported as the single most debilitating side effect reported by patients undergoing HCT. The incidence of HCT mucositis among adults is estimated to range between 76% and 89%; however, comparisons are difficult due to variability in patient ages, treatments and criteria for scoring oral mucositis. The use of intra-oral photobiomodulation (PBM) therapy in adult patients after the development of oral mucositis is well documented and now included in the international mucositis guidelines, with limited evidence in pediatrics. This study will build evidence for the incorporation of extra-oral PBM therapy into daily nursing care of children and adolescents undergoing HCT. This intervention has potential in providing evidence for efficacy in the prevention and treatment of oral mucositis, the single most debilitating side effect reported by patients undergoing HCT. Primary Objective: * To evaluate feasibility and efficacy of photobiomodulation therapy (PBM) in reducing oral mucositis in children and adolescents at risk for grade 3 oral mucositis undergoing an allogeneic hematopoietic cell transplant (HCT). Secondary Objective: * To compare clinical manifestations associated with the development of oral mucositis between those treated with daily PBM and a matched control. Clinical factors to include: grade and duration or oral mucositis. Exploratory Objective: * To evaluate efficacy of photobiomodulation therapy in autologous patients at risk for grade 3 oral mucositis compared to matched control. * To evaluate utilization of play-based procedural preparation and treatment feasibility and parental satisfaction.

Detailed description

Children, adolescents and young adults admitted for an allogeneic HCT and those determined by the transplant team to be at risk for grade 3 oral mucositis will be eligible to receive PBM (34 x 660nm 10mW, 35 x 850nm 30mW: 1390 mW total power output) at an irradiance of 50mW/cm2. The PBM treatment will be administered via the THOR Model LX2M unit. After low light therapy consent, participants will be offered the opportunity to receive a play-based preparation. Those who elect to receive this child life preparation will be scheduled to meet with a trained certified child life specialist (CCL) prior to admission. The play-based preparation will incorporate age and developmentally appropriate explanations of the non-invasive procedure and will be adapted to each patient's psychosocial and cognitive developmental needs. Observation and treatment will begin the first day of conditioning (plus/minus 2 days). Those undergoing an allogeneic HCT will have treatment daily until Day +20 or engraftment (ANC ≥ 500 for two consecutive days). For those undergoing an autologous transplant, treatment will continue until engraftment (ANC ≥ 500 for two consecutive days) or until the patient is without mucositis for two consecutive days. The PBM will be administered extra-oral and intra-oral by trained research staff. Direct aim of the laser into the eye will be avoided and safety spectacles will be used with laser therapy. The safety spectacles will be prescribed according to age, with the adjustable Ibis Infant eye protection for patients less than 1 year of age and the adjustable kids laser safety googles for the young child. Patients, staff, and observers will wear laser safety glasses while PBM is in use. The parent may hold the device in place with assistance from the trained persons. After the initial LLLT treatment, a parent-reported satisfaction survey will be administered via paper questionnaire. The observation of oral mucositis will be conducted by non-study staff and conducted as clinical care by the nurse, advanced practice provider and/or physician. Each patient will have a daily oral assessment, with documentation of mucositis, grade, duration, pain assessment, days of nutrition support, use of narcotics, positive oral and blood cultures. All patients will receive the standard mouth care regimen prescribed for transplant patients. Each patient will be matched and compared to a previously treated patient. The comparison will be matched on primary disease, conditioning regimen, age and sex, with comparison of treatment variables of mucositis grade, duration, pain medications, days of nutritional support, blood and oral cultures, to day +20 or engraftment (depending upon which occurs first).

Interventions

DEVICEPhotobiomodulation Therapy (PBM)

The PBM will be delivered through application of the LED Cluster Probe externally to the right external buccal, left external buccal, mid face with mouth open and submandibular and left/right cervical. Patients who develop an oral lesion, intra-oral directed therapy will be administered with the dental light probe. For patients that can tolerate, an intraoral probe will deliver light directly onto the oral mucosa, this will then replace the mid face application with mouth open. Each laser application will be timed at 60 seconds.

OTHERPain and Oral Function Assessment

After the 6-minute laser/ treatment session the child and parent will complete the mucositis evaluation scale on paper or ipad which includes self-report oral function specific to ability to swallow, eat and drink, as well as the patient's self-reported need for medication specific to mouth pain.

OTHERParent-Reported Satisfaction Survey

A parent-reported satisfaction survey will be administered via paper questionnaire after the initial LLLT treatment. Parent satisfaction will be reported by parents on a 5-point Likert scale to questions adapted from a parent satisfaction survey used in a study regarding child life services in pediatric imaging.

Assess the Severity of Mucositis Grade 1-3 and Duration for Each Patient Treated With PBM Compared to Matched Controls

Patients were ranked according to the severity of their mucositis (a weighted average of mucositis intensity (grade 1-3) by number of days duration)

Time frame: Daily assessment from day 1 of conditioning to 20 days after transplant or engraftment (2 consecutive days of an Absolute Neutrophil Count (ANC)>500)

Population: Within each grade of mucositis (1-3) participants and controls were ranked against each other by days of mucositis duration. Each participant and control had 3 rankings for the 3 mucositis grades. The weighted average for each participant and control was calculated. Within each group (participant vs. control) there was a ranking (1-35 with the lower score being more severe mucositis). Statistical analysis then compared the weighted average between the two groups.
