Filter by:Previous studies of this type of head and necl cancer have shown high rates of cancer control but result in many short and long term side effects when treated with high dose radiation and chemotherapy. Recently, investigators have noticed similar high rates of cancer control in small numbers of patients who receive less intensive treatments using lower doses of radiation, smaller radiation fields with chemotherapy. It is expected that the side effects of treatment with lower doses of radiation would be less. For this reason this study is looking at a different regimen of reducing the intensity of the treatment. The purpose of this study is to compare any good and bad effects of using lower dose smaller fields radiation therapy and chemotherapy with published outcomes. This study will allow the researchers to know whether these different approaches are better, the same, or worse than the usual approach. To be better, the study approach should result in the same survival rate of the usual approach (about 85 out of 100 patients alive and free of cancer at 2 years) but with less long-term side effects.
Radiation-induced xerostomia (dry mouth) is one of the most common and severe toxicities experienced by patients undergoing radiation treatment for head and neck cancer. Radiation-induced dry mouth is a frequently experienced symptom and persists after treatment, potentially indefinitely. Current practice does not specifically attempt to spare the parotid ducts, where stem/progenitor cells are believed to preferentially reside, and considers the entire salivary gland to have equal function. New radiation therapy planning and conducting strategies are needed to reduce this toxicity and maximize patient quality of life post-treatment. This randomized Phase II study explores the contribution of magnetic resonance imaging (MRI) guided salivary gland duct definition to decrease patient-reported xerostomia in patients with oropharynx cancer receiving radiation therapy. The severity of xerostomia will be measured by patient-reported (PRO) symptoms, saliva secretion, saliva pH, and buffering.
This is an exploratory qualitative study among People Living With HIV (PLWH) of diverse racial/ethnic and sexual and gender minority (SGM) identities to explore individual, interpersonal, and structural oral health equity factors that serve as barriers or facilitators of accessing oral health care, knowledge and perceptions of human papillomavirus (HPV) vaccination and Oral squamous cell carcinoma (OSCC) /Oropharyngeal squamous cell carcinoma (OPSCC), and to collect recommendations on how to increase access to oral health care and engage PLWH in OSCC/OPSCC prevention.
The purpose of this research is to determine whether it is feasible to treat patients with Human Papilloma Virus positive (HPV-positive) oropharyngeal tumors on a specialized treatment machine (MRIdian linear accelerator [Linac]), which utilizes magnetic resonance imaging (MRI) for radiation planning and delivery.
The goal of this study is to determine the feasibility of administration of a single dose of E7 TCR-T cells as induction therapy prior to definitive treatment (chemoradiation or surgery) of locoregionally advanced HPV-associated cancers. The intent of E7 TCR-T cell treatment is to shrink or eliminate tumors and thereby facilitate definitive therapy and increase overall survival. This study seeks to determine 1) if E7 TCR-T cell can be administered without undue delay in definitive treatment, 2) the tumor response rate to E7 TCR-T cell treatment, 3) and the disease-free survival rate at 2 and 5 years. Participants will undergo an apheresis procedure to obtain T cells that will be genetically engineered to generate E7 TCR-T cells. They will receive a conditioning regimen, a single infusion of their own E7 TCR-T cells, and adjuvant aldesleukin. Participants will follow up to assess safety and determine tumor response and will return to their primary oncology team for definitive therapy.
This is a multicenter, open-label, Phase I, first-in-human trial to characterize the safety and clinical activity of an antigen-specific CD8+ T-cell product in patients with relapsed or refractory locally advanced or metastatic HPV-related oropharyngeal cancers. Patients must have received at least one prior standard treatment regimen consisting of systemic immunotherapy and/or chemotherapy. The investigative agent is an autologous adoptive T-cell product derived from the patient's endogenous cytolytic T cells that are directed toward HPV-16 E6/E7, HPV-18 E6/E7 antigens, and a tumor-associated antigen (Survivin) by ex vivo exposure to an artificial antigen presenting cell to which HLA-A2 antigen-peptides have been fit within the pocket of an MHC class 1 molecule. Patients must express HLA-A*0201.
The oropharyngeal areas mainly comprises of the tonsil, base tongue (BOT), soft palate and the posterior pharyngeal wall. Traditionally, surgical resection of oropharyngeal cancers (OPC) was a standard procedure, often performed through mutilating incisions with mandibulotomies, rendering significant post-operative functional deficits. Over the past 2 decades, there has been a major shift in treatment strategy with a majority of these cancers now being treated by primary concurrent chemoradiation (CCRT) with a trend towards organ and function preservation.
The PEARL study will recruit approximately 50 patients with human papillomavirus (HPV)-positive oropharyngeal squamous cell carcinoma (OPSCC) who are about to undergo primary treatment with concurrent chemo-radiation from South Wales (Velindre Cancer Centre and Singleton Hospital, Swansea) and Bristol. The main aim is to see whether it is feasible to preform a positron emission tomography-computed tomography (PET-CT) scan after 2 weeks of radiotherapy and re-plan the radiotherapy based on this PET-CT scan, to re-distribute the dose of radiotherapy being delivered, so that a smaller area of normal tissues in the mouth and throat are treated to a high dose of radiotherapy.
