Filter by:NRF2 activation, observed in up to 40% of head and neck squamous cell carcinoma (HNSCC) tumors, plays a critical role in tumor progression, metastasis, and radiation therapy resistance. The investigators have recently discovered that pyrimethamine (PYR) and its analogs have an inhibitory effect on NRF2 activity in vitro and in mouse models via inhibition of dihydrofolate reductase (DHFR). Pyrimethamine is an established drug that has been used for decades for treatment of protozoan infections and malaria. A growing body of research shows that it has potential antitumor activity, however its activity on growing human tumors has not been previously studied. The primary efficacy goal of this study is to evaluate the activity of pyrimethamine on human tumors as demonstrated by inhibition of DHFR and downregulation of NRF2 pathway activity. On-target inhibition of DHFR by pyrimethamine results in the stabilization and increased protein expression of human DHFR. The primary efficacy hypothesis of this study is that treatment with pyrimethamine will result in a 50% increase in DHFR protein within the tumor cells as measured by quantitative western blot analysis. Secondarily, among those tumors classified as NRF2-active on pre-treatment biopsy, the investigators hypothesize there will be a 50% reduction in NRF2 activity as measured by SureQuant targeted proteomic analysis.
Aim: To evaluate the effectiveness of thymus honey on radiation induced-oral mucositis and xerostomia. Background: Oral mucositis and xerostomia are two of the most severe side effects that head and neck cancer patients confront during and after the completion of radiotherapy. Although several medications are used for their treatment, these fail to provide a fully effective and comprehensive management. Honey and thyme have been studied for the management of various treatment-related side effects. Design: Α double blinded randomised controlled trial will be used for this study. Methods: 200 head and neck cancer patients who receive radiotherapy will be included in this study. Patients will be randomised and divided into two equal groups of 100 participants; the intervention group (oral spray with thyme and honey + standard care) and the control group ( placebo spray + standard care). Assessments with xerostomia and oral mucositis scales additionally to 4 self-administered questionnaires will occur in both groups at baseline and then weekly and 6 months following completion of treatment. The duration of the study will be 3 years from the day of approval of this research protocol.
In this study, the study team seek to conduct a pilot clinical study to evaluate the safety and efficacy of a reformulated proton pump inhibitor (PPI) cream (Dermaprazole) in definitive head and neck cancer (HNC) patients.
This is a phase Ib study with a safety lead-in (n = 6 per arm) evaluating combinatorial DPV-001 + sequenced PD-1 blockade, with or without GITR agonist, in recurrent or metastatic HNSCC.
This trial will explore giving standard dose chemotherapy and radiation therapy to sites of disease including all lymph nodes involved with HPV-positive oropharyngeal cancer, but administer lower doses of radiation therapy to the lymph nodes that are not known to be involved with cancer. By doing so, it is hypothesized that there will be equally good long term loco-regional and distant disease control but will reduced long term treatment side effects and improved quality of life in persons living well beyond their cancer treatment.
This study will assess the benefit of postoperative adjuvant radiotherapy in patients with an early oral squamous cell carcinoma (OSCC) having tumor thickness more than or equal to 5mm. The study population will consist of patients who have been treated by surgery for early stage oral tongue cancers. Patients with a close or positive margin (</= 5mm) and or with metastatic neck node(s) will be excluded. Selected patients will be randomized into two groups. The group I will be observed after surgery and group II will receive adjuvant radiotherapy as per protocol.
Radiation therapy for head and neck cancer (HNC) is associated with the development of swallowing difficulties, or dysphagia. Dysphagia has profound negative effects on the health, nutritional status, and quality of life of HNC survivors. It also puts them at risk of developing life-threatening aspiration pneumonia. Radiation-associated dysphagia can be intractable and not responsive to conventional dysphagia therapy. HNC survivors with chronic severe dysphagia may be dependent on long-term tube feeding. Expiratory Muscle Strength Training (EMST) is a low-cost, device-driven therapy. It has been studied as an approach to simultaneously improve cough and swallowing functions. During EMST, patients forcefully expire into a one-way spring-loaded valve to strengthen expiratory and submental musculature. The EMST-150 device is available for clinical use in Singapore. In other research studies, it has been shown to improve cough and swallowing in several populations of people with chronic dysphagia, most recently in people with chronic radiation-associated dysphagia. The investigators propose to study the effect of EMST using the EMST-150 device on cough, airway protection, and swallowing functions of HNC survivors with radiation-associated dysphagia. The investigators will recruit 40 participants to undergo an 8-week EMST programme, with weekly follow-up to calibrate their EMST device. It is hypothesised that EMST will improve participants' respiratory and swallowing functions. Respiratory function improvement will be shown by increased maximum expiratory pressure and improved cough airflow measures. Swallowing function improvement will be evidenced by reduced aspiration or improved ability to clear aspirated material during videofluoroscopic swallow studies. The investigators also hypothesize carryover effects on other aspects of swallowing, such as improved hyoid and laryngeal excursions, and improved laryngeal vestibule closure. With the results of this study, the investigators aim to develop better evidence-based rehabilitation programmes for HNC survivors, and those living with chronic dysphagia.
Fluorescent technology continues to advance in the detection of sentinel lymph nodes (SLNs). Currently, this requires switching from near-infrared light to white light to be able to identify the fluorescent tissue contrasting with normal surrounding tissue. Currently, no system has been studied specifically for head and neck sentinel lymph node biopsies using a hands free goggle system that can visualize white light (normal surgical visualization) and nearinfrared light (ICG fluorescence) simultaneously. This technology may have implications on the safety and accuracy of sentinel lymph node biopsy for head and neck mucosal and cutaneous tumors. Secondarily, this may reduce operative costs by decreasing the amount of time required to perform the SLNB procedure. Regarding parathyroid identification, this technology has the potential to identify these very small glands during procedures they are at risk. These glands are not only at risk of inadvertent removal if not adequately identified, but may also be at risk if devascularized by manipulation during the surgical procedure. Therefore, early and accurate identification may decrease the rate of temporary and permanent hypoparathyroidism and hypocalcemia. This is not only an issue during thyroid and parathyroid surgery, but during laryngectomy surgery where the anatomic region these glands are located are often resected to remove at risk lymph nodes from cancer spread. Therefore, identifying these glands may help preserve parathyroid function in this patient population as well.
This study will aim to demonstrate that implementation of a rapid, multidisciplinary supportive care program for patients receiving chemoradiotherapy who are deemed to be at high risk for hospitalization based on real-time pedometer data will reduce the rate of hospitalization during chemoradiotherapy or within four weeks of radiotherapy completion.
A phosphate supplement is part of the treatment of patients with the refeeding syndrome (RFS). It is not known, if the generalized edema also affects the intestine to decrease absorption. The aim was to investigate, if oral treatment is possible in mild to moderate RFS. In a randomized crossover design 12 hospitalized head-neck cancer patients ingested four oral solutions of phosphate in two-day periods. In a low-dose period the investigators compared five mmol phosphate from either skimmed milk or Di-sodiumphosphate-di-hydrate and potassium di-hydrogens-phosphate with black currant flavor (PBC), and in a high-dose period 20 mmol from either Addiphos® or the PBC-solution. P-phosphate was measured two and four hours after the ingestion, the urinary excretion after four hours. P-phosphate significantly increased after PBC in both the low- and high-dose and Addiphos®, but not after skimmed milk. The increase was larger after Addiphos® than the PBC-solution. There was no difference in the increase between the patients with low p-phosphate and those with normal values, and no correlation between baseline p-phosphate and percent increase. There was no group difference in the urinary excretion of phosphate. The investigators conclude that phosphate can be readily absorbed after oral administration, but skimmed milk can´t be recommend for this purpose.
