Oral Care Program for Mouth Side Effects During Head and Neck Radiation Therapy

People having radiation therapy to the head and neck often develop painful mouth problems - mouth sores, dry mouth, mouth pain, trouble eating and drinking, and changes in taste. These problems can become severe enough to interrupt radiation treatment or lead to an emergency room visit or a hospital stay. This study is testing whether an oral care program called OSEM (Oral Side-Effect Management) reduces how severe those mouth problems become. Fifty adults starting radiation to a head and neck site at Premier Cancer Center will take part. Each person will be assigned by chance, like a coin toss, to one of two groups: One group receives the Peace of Mouth Kit - everyday mouth care products including dry mouth candies, ginger candies for nausea, a mouth rinse, a sensitivity toothpaste, a soft toothbrush and a lip balm - together with a short check-in each week with a member of the Premier team right after their radiation treatment. The other group receives their usual care at Premier, unchanged. Everyone in the study fills out the same short questionnaire about their mouth each week during radiation, and once more about four weeks after their last treatment. Everyone continues to see their radiation doctor every week, exactly as they would if they were not in the study. Taking part lasts about 11 weeks in all. The items in the kit are everyday consumer mouth care products. They are not medicines of any kind, and the U.S. Food and Drug Administration has not approved them to treat or prevent any disease.

Gut Microbiome in Gynecological Cancer Patients With Pelvic Toxicity: Controls Versus Ozone Treatment. (MicrOzoGineTox)

Patients treated for gynecological tumors with radiotherapy (RT) and/or chemotherapy (CT) frequently develop pelvic toxicity (TPIRQT), a condition that can become persistent, progressive, and refractory to standard treatments. This toxicity, affecting the rectum (proctitis), bladder (cystitis), and vagina (mucositis), severely deteriorates quality of life. Standard options for refractory cases are limited; at our center, rectal ozone therapy is used with high rates of symptomatic improvement (66-75%). Emerging evidence suggests a link between gut microbiota and the development of TPIRQT. However, it is unknown how rectal ozone therapy may influence the gut microbiome or if this modulation is part of its therapeutic mechanism. This prospective observational study will investigate the potential relationship between gut microbiome profiles (composition and diversity), the presence and severity of TPIRQT, and the response to rectal ozone therapy.

Retrospective Observational Study of Oral Complications and Quality of Life in Head and Neck Cancer Patients Treated With Radiotherapy or Chemoradiotherapy.

Head and Neck cancer patients receiving radiation therapy (with or without chemotherapy) suffer several oral complications, such as oral mucositis, which impairs quality of life of patients during radiotherapy and in the post-treatment follow-up period. The use of topical agents to protect oral mucosa against radiation-induced toxicity is part of the routine clinical practice. Among these products, the use of mouthwashes and/or gels are extensively used in the Centro Oncológico Clara Campal - Hospital HM Sanchinarro. Once such product is a proprietary formulation based on natural ingredients such as olive oil, betaine, and xylitol (Mucosa Innovations S.L.).

Bevacizumab Versus Corticosteroids as First-line Treatment in Patients With Symptomatic Cerebral Radiation Necrosis After Radiation for High-grade Glioma or Brain Metastases

Cerebral radiation necrosis (CRN) is a severe complication of high-dose radiation for brain metastases (BM) or glioma, which can potentially cause significant neurologic symptoms leading to serious morbidity and impaired quality of life (QoL). The first-line therapy for symptomatic CRN (sCRN) is corticosteroids, primarily dexamethasone, which often leads to complications, refractory symptoms, and interference with anti-cancer treatment. Since 2017, bevacizumab, an antibody against Vascular Endothelial Growth Factor (VEGF), has been used in a second-line treatment setting for refractory sCRN. A small randomized clinical trial (RCT) has shown that bevacizumab significantly diminishes cerebral edema on MRI and decreases clinical symptoms of sCRN in irradiated glioma patients. Several non-randomized clinical studies demonstrated a beneficial radiological and clinical effect of bevacizumab in patients with sCRN after irradiation for BM. The optimal first-line treatment for sCRN is currently unknown. Effective and safe first-line treatment of sCRN will optimize the patient's well-being and health-related QoL. Furthermore, minimizing corticosteroid use will benefit the clinical treatment options and outcomes of concomitant or future anti-cancer treatment. This phase III multicenter, open-label, randomized clinical trial compares the clinical efficacy of first-line bevacizumab versus standard-of-care dexamethasone for sCRN in patients with high-grade glioma (HGG) or BM.

Shared Decision Making on Radiation Dose for Lung Malignancies

A Patient Decision Aid (PtDA) is developed during a workshop in close collaboration with selected patients. The PtDA is subsequently used in the consultation between patient and physician to facilitate their shared decision on the dose of stereotactic body radiation therapy (SBRT) for lung tumors located less than 1 cm from the thoracic wall. Hypothesis: The use of a PtDA will increase the extent of Shared Decision Making (SDM) during the consultation and result in patients being more directly involved in the planning of their treatment.

HRQL and Symptom Assessment for Patients With DIPG or Recurrent and Re-irradiated Brain Tumours and Their Caregivers

Although many children with brain tumours are successfully cured of their disease, a substantial proportion of patients suffer disease recurrence and require further treatment. This therapy may involve a repeat course of radiation (RT2). Based on retrospective data, re-irradiation may provide palliative and even potentially curative benefit. However, such retrospective data are subject to bias, which may over-report survival and under-report toxicity. Furthermore, we do not know how re-irradiation affects patients' HRQOL. The goal of this research is to prospectively describe the HRQOL of patients diagnosed with DIPG and recurrent brain tumors and their families before and after re-irradiation to more accurately assess the benefit versus the toxicity of this treatment. In addition, if we are able to demonstrate the feasibility of collecting HRQOL information on a routine basis we will be able to justify the need to conduct this research further and implement HRQOL screening as a standard of care for these patients. Re-irradiation for children with DIPG and recurrent brain tumours will not cure these children from their disease but may improve neurological function and wellbeing. We postulate that the opportunity of more time to say the final good bye and creating memories will facilitate bereavement and prevent psychological dysfunction of parents and siblings. A greater understanding of what helps these families may enable clinicians to better support these children and their families in this difficult disease course. Ultimately our goal is to improve the psychological experience of these patients and their families.

Prospective Randomised Phase II Trial Evaluating Adjuvant Pelvic Radiotherapy Using Either IMRT or 3-Dimensional Planning for Endometrial Cancer. ICORG 09-06

Post-operative radiotherapy is internationally accepted as standard practice in the management of high-risk endometrial cancer1. Whilst it has no proven impact on overall survival it significantly increases local control. Conventional radiotherapy techniques (3-dimensional) utilise a 3 or 4 field beam arrangement to target the pelvis in order to treat those areas at risk of recurrence: the vagina, the parametrium and the pelvic lymph nodes. However, when using such a technique it is not possible to avoid irradiating sensitive normal tissues such as the bowel and bladder. Toxicity data from international randomised control trials in endometrial cancer report significantly more haematological, gastrointestinal, genitourinary and cutaneous toxicites (all grades) in those who received pelvic irradiation compared to those who did not2,3. These trials delivered radiotherapy using 2 or 3-dimensional techniques. Intensity Modulated Radiation Therapy (IMRT) is a newer but established radiotherapy technique in many tumour sites that allows us to much more tightly conform the radiation. It uses computer-generated beams to produce radiotherapy volumes that can avoid irradiation of normal tissues in the pelvis. There are no randomised studies reported in the literature that compare 3-dimensional pelvic irradiation with IMRT in patients who have had surgery for endometrial cancer. However there are several small studies that report considerable sparing of normal tissues using IMRT and when compared retrospectively with conventionally treated patients demonstrate marked reductions in acute gastrointestinal and genitourinary toxicity4. By delivering post-operative radiotherapy to the pelvis using IMRT (as opposed to the standard 3-dimensional technique) it is anticipated that whilst local control and survival will be unaffected acute and late toxicity will be reduced.

Curatively Intended Thoracic Reirradiation

The number of long-term lung cancer (LC) survivors increases, however many patients are diagnosed with recurrent or new thoracic cancers. High-dose reirradiation (reRT) is promising but associated with high severe toxicity rates. Existing studies are small lacking high-quality data, with no clear correlation between toxicity risk and delivered radiotherapy (RT) dose. This Danish multicentre prospective cohort study aims to provide a framework for collecting radiotherapy-related toxicity data, loco-regional control, and overall survival data for patients with thoracic cancer undergoing reirradiation; with the ultimate aim of providing safe reirradiation to more patients. As a secondary aim, guidelines for dose accumulation and provisional constraints for the organs at risk will be used to establish a uniform treatment strategy for reirradiation. The CURE Lung trial will provide high-impact, globally missing data. This project will ensure full utilization of and learning from the trial, adding SDM, PROMs, and modality referral to the trial. It will model the correlation between toxicity burden and doses, enabling individualized reRT with optimized dose prescription based on toxicity risk and patient preferences, and assisting in the decision-making on the prescription dose and optimal modality. This will ensure safe reRT for the increasing number of long-term LC survivors.

DENTOFACIAL-PBT Stage 2 - Feasibility Study

What is the health problem? Proton beam therapy (PBT), a type of radiotherapy treatment, can be especially beneficial to children and teenagers with cancer. PBT works by damaging cancer cells, but it can also damage healthy parts of the body nearby. This can include the teeth and jaws if the cancer is in the head and neck region. Unfortunately, the investigators do not yet fully understand the potential side effects of PBT on the teeth or jaws. What is the aim? The DENTOFACIAL-PBT research project aims to learn about the side effects to the teeth and jaws in children treated with PBT. This stage of the research aims to determine how frequently issues ('toxicities') in the development of the teeth and growth of the jaws have occurred in previously treated patients. DENTOFACIAL-PBT is funded by the National Institute for Health and Care Research. How is the researched being approached? The investigators will ask head and neck childhood cancer survivors treated with PBT overseas or in Manchester to support this research. Surveys will be sent initially, asking questions about their teeth and jaws after treatment. If interested, these survivors can be involved in the next part of this stage, which is a mixed-methods feasibility study. This will involve online interviews and dental assessments with some and the collection of dental information from a participant's dentist. Radiation dose to the teeth and the jaw bones will then be linked to any side effects seen. What will be the outcome? The information gained in this study will allow the research team to look at how age, location and amount of dose given affects the toxicities seen. Information learnt will help develop the final stage of the DENTOFACIAL-PBT study. In this, a new toxicity reporting tool will be developed which aims to improve the communication between dentists, doctors, and cancer patients.

Neurocognitive Impact of Different Irradiation Modalities for Patients With Grade I-II Skull Base Meningioma:

For the purpose of this research, investigator will constitute several cohorts of patients, treated either by intensity-modulated radiotherapy, stereotactic radiotherapy or proton-therapy. This will allow better understanding the cognitive and anatomical damages caused by new radiotherapy techniques and better understanding how ionising radiation (X-rays or protons) acts in the long term on brain tissue. Longitudinal follow-up will be multimodal, based on yearly multi-parametric brain MRI to assess morphological changes, in relation with dosimetric data as well as neuropsychological performances, health-related quality of life, anxiety and depression disorders, memory tasks, and socio-professional reintegration. This will notably make it possible to evaluate the relationship between dosimetric data, age at the time of treatment, region of the brain irradiated, type of radiation used, dose per fraction, neurocognitive and neuro-anatomical consequences. A Normal Tissue Control Probability (NTCP) model will be also developed. Overall, the results of this study should contribute to the improvement of treatment techniques, in particular by preserving as much as possible the significant cerebral zones (hippocampi, frontal lobe, sub-ventricular zones, etc.), and to the management of patients by proposing appropriate support measures. In the proton-therapy cohort, evaluations will make it possible to establish more precisely the place that this new irradiation strategy should occupy in the management of low grade meningioma. Importantly, investigator have planned to constitute a last cohort, with subjects free of any neurological disease, to make it easier the interpretation of cognitive performances over time among patients in the three brain radiation cohorts.
