F.L.O.S.S. Project (Facilitated Lessons on Oral and Systemic Health in Survivors)

The goal of this study is to assess the efficacy of a Telehealth Intervention (THI) in 1) yielding more favorable oral health outcomes (e.g., reduced treatment-related mucositis, reduced gingival inflammation, tooth preservation); better oral health-related quality of life (OHRQoL). The investigators will also assess the efficacy of THI in yielding decreased systemic inflammation compared to usual care (UC).

The Study population will comprise 100 unselected cancer survivors who will be recruited through community-based approaches. The goal is to enroll 50 active treatment and 50 post-treatment into the study.

Intraoral Imaging All participants, prior to randomization will undergo an intraoral imaging assessment.

Intraoral imaging will be conducted on all study participants at the time of their baseline in- person visit. Photos of the mouth, teeth, and gums will be captured and saved in individual patient files for research and data purposes only. The images captured by the intraoral imaging exam will not be uploaded to any electronic healthcare records for dentist or hygienist use; these images are strictly for the use of research staff. These images will be the data for the study, as both baseline and succeeding follow-up images will be taken. These images will be used to analyze the oral health and overall quality of life of the subjects. The investigators will have a dental consultant review images and provide summary data.

Biospecimens Saliva samples will be collected at baseline, 6-,and 12-month post-randomization.

Participants will self-collect the saliva sample using the Omnigene Saliva DNA and RNA device (OMR-610). Blood samples (10 mL) for biomarker assessments at baseline and follow-up visits (i.e., 6- and 12- months) Inflammation markers including C-reactive protein, IL-1, IL-6, and TNF-alpha will be measured. Samples will be processed within two hours and stored at -70°C. Saliva samples will be stored for up to 21 days at room temperature, and then will be stored at -20 °C. Human and microbial DNA and RNA will be extracted to examine oral microbiome.

Survey Instruments Basic demographics and lifestyle characteristics will include smoking, physical activity, and diet, clinical characteristics, cancer-treatment questionnaire, EORTC oral and overall quality of life questionnaires (QLQ-C30 and OH-15), Oral Health Impact Profile (OHIP-14), patient-reported oral mucositis symptom scale, and Area Deprivation Index.

Anthropometric measures of height, weight, waist and hip circumference will also be collected. All survey and anthropometric measurements will be collected at baseline, 6- and 12- month post-randomization.

Clinical Trial Arms This is a six-month 2-arm randomized controlled trial comprising a Telehealth Intervention (THI) arm and a Usual Care (UC) arm as described below

Telehealth Intervention (THI) This is based on e-Health and mobile Health and utilizes the use of information and communication technologies for health. More specifically this telehealth method is a medical and public health practice that is supported by mobile devices, such as mobile phones, patient monitoring devices, personal digital assistants, and other wireless devices. This method allows for the monitoring of oral health conditions and alert the patient or oncologist about an emerging oral health issue. Moreover, telehealth reduces the need to come into an office for a visit.

Outcomes

The following outcomes will be measured in all participants at baseline and repeated at 6 and 12 months:

ORAL HEALTH OUTCOMES

1. mucositis: clinical via intro-oral imaging using the WHO oral mucositis grading scale) and the patient-reported oral mucositis symptom scale (PROMS) questionnaire
2. gingival inflammation and periodontal disease: Modified Gingival Index based on intraoral imaging
3. tooth decay: Delayed, Missing, Filled Teeth (DMFT) index based on intraoral imaging
4. oral health related quality of life: Oral health Impact Profile (14-item OHIP-14 questionnaire) and the cancer specific oral health questionnaires (EORTC Quality of Life Questionnaires - oral health)

SYSTEMIC OUTCOMES

1. systemic inflammation: Inflammation markers measured in peripheral blood samples
2. overall health related quality of life: measured using EORTS QLQ-C30 questionnaire
3. comorbidities: cardiovascular and metabolic comorbidities including diabetes, hypertension, heart disease, and stroke will be determined from the medical record

Statistical Analysis Demographic and other baseline data including cancer-related clinical characteristics will be listed and summarized descriptively by intervention arm (THI and UC). Categorical data will be presented as frequencies and percentages. For continuous data, mean, standard deviation, median, minimum, and maximum will be presented. For selected parameters, 25th and 75th percentiles will also be presented.

Intention to treat (ITT) analysis will be performed for all participants who enrolled and randomly allocated to one of the clinical trials arms to which they were randomized. Descriptive statistics will be used to summarize the original scores for the outcomes (oral and systemic health outcomes), as well as change from baseline, at each scheduled assessment timepoint for the THI and UC group. Additionally, change from baseline in the scale and subscale values at the time of each assessment will be summarized. Participants with an evaluable baseline score and at least one evaluable post baseline score during the treatment period will be included in the change from baseline analyses.

The number of participants completing each questionnaire and the number of missing or incomplete assessments will be summarized by treatment group for each scheduled assessment timepoint. A repeated measurement analysis model for longitudinal data will be used to estimate differences in the scores of mucositis, oral and systemic inflammation, tooth decay, and oral and overall quality of life between the THI and UC arms. The differences in least square means between the treatment arms and corresponding 95% confidence interval at selected timepoints will be presented. Details, including handling of missing data, will be specified in the detailed protocol for the study.
