Brief summary

This clinical trial studies the effect of customized 3 dimensional (3D) printed oral tents on patients with head and neck cancer who are receiving radiotherapy. Oral stents are made from the impression of patients' mouth and cover patients' teeth and gums during radiation therapy. A customized, 3D-printed oral stent may help to reduce mouth blisters and/or sores that may develop in patients while receiving head and neck radiation therapy.

Detailed description

PRIMARY OBJECTIVE: I. To evaluate the acute mucositis rates in non-target mucosa of patients who receive head and neck radiation with or without a customized 3D printed oral stent. SECONDARY OBJECTIVES: I. To record patient reported outcomes during radiotherapy. II. To evaluate patient narcotic use during radiotherapy. III. To evaluate the imaging and dosimetric differences in head and neck radiotherapy with and without a customized 3D printed oral stent. OUTLINE: Patients are randomized to 1 of 2 arms. ARM I: Patients wear 3D printed oral stent during standard of care radiotherapy. ARM II: Patients receive standard of care during treatment.

Design outcomes

Primary

MeasureTime frameDescription
Mucositis toxicity ratesThrough study completion, an average of 1 yearRate of non-target mucose will be estimated along with the corresponding 95% confidence interval. Cochran-Mantel-Haenszel (CHM) test will be applied to compare mucositis rates between the two treatment arms. Logistic regression will be used to compare occurrence of mucositis between two arms, adjusting for the effects of stratification factors as well as other covariates. T test or Wilcoxon rank sum test will be used to compare three Olerud-Molander Ankle Score between two arms: a mean mucositis score, an extent of mucositis score, and a worst site score.

Secondary

MeasureTime frameDescription
Patient reported outcomesThrough study completion, an average of 1 yearWill be assessed using the MD Anderson Symptom Inventory Head and Neck questionnaire. T test or Wilcoxon rank sum test will be used to compare scores of each item per time point or sums of scores across all items at each time point or sums across three time point per item between the two arms. Multivariate analyses such as linear regression model adjusting for the effects of covariates might be performed to compare patients reported outcomes. Appropriate data transformation will be performed if necessary for assumption of normality.
Patients narcotics diariesThrough study completion, an average of 1 yearWill record the worst, the least, the average pain score and pain score at present for each day. Will calculate the average of these 4 scores as a composite daily pain score.
Imaging differenceThrough study completion, an average of 1 yearThe set up error during radiation will be measured in each treatment arm.
Dosimetric differenceThrough study completion, an average of 1 yearThe radiation dose to healthy tissue will be measured in each treatment arm.
Composite pain scoresThrough study completion, an average of 1 yearAn area under curve of pain scores over two weeks (AUC2wks) will be calculated for each patient, and the t test or Wilcoxon rank sum test will be used to compare the AUC2wks of pain scores between the two arms, and between patients with and without occurrence of mucositis in their non-target mucosa. Will also fit linear mixed models including patients as random effects to compare the composite pain scores over two weeks between treatment arms. The linear mixed models will also be fitted to evaluate the association of composite pain scores with occurrence of their non-target mucosa.
Number of narcotic pills usedThrough study completion, an average of 1 yearAn AUC2wks will be calculated for each patient, and the t test or Wilcoxon rank sum test will be used to compare the AUC2wks of pain scores between the two arms, and between patients with and without occurrence of mucositis in their non-target mucosa. Will also fit linear mixed models including patients as random effects to compare the composite pain scores over two weeks between treatment arms.
