Filter by:Our main objective is to evaluate the effect of Ocoxin-Viusid on the quality of life of patients with advanced stomach cancer and esophagogastric junction. The Ocoxin-Viusid nutritional supplement is expected to improve quality of life and tolerance to treatment with Chemotherapy.
66% of HNC patients present with advanced-stage disease at initial diagnosis. The 5-year survival rates for stages IVa, IVb, and IVc are 32%, 25%, and <4% respectively. Accurate pre-treatment staging is vital in determining the optimum procedure for the management of HNC. Early identification of non-responders may allow modification of their treatment through the introduction of more intensive therapies. Identifying prognostic factors that predict patient outcome will ultimately lead to new treatment regimens. Tumor hypoxia and proliferation are two key characteristics of cancer that were shown to correlate with poor response to treatment in HNC. In this proposal, the investigators assess the prognostic values of these two markers. Combining information from these two biological markers shall result in prognostic information superior to those of any of the two separately. Imaging those vital tumor characteristics simultaneously shall provide more coherent assessment of tumor microenvironment than does registration of corresponding images acquired in different imaging session, thus subject to uncertainties resulting from transient biologic changes and image registration process. The investigators propose to use a method that the investigators previously developed to simultaneously and non-invasively image tumor hypoxia (FMISO-PET) and proliferation (FLT-PET) within a single PET/CT study. CT Perfusion scan will be performed 1st, followed by PET imaging with staggered FMISO and FLT injections. FMISO and FLT signals will be separated retrospectively using kinetic modeling. The investigators believe imaging tumor hypoxia and cell proliferation simultaneously yield information underpinning for image-guided and radiobiological based dose painting, adaptive therapy, and patient medical management. If successful, this pilot study will constitute the basis for a NIH grant proposal that aims to improve treatment outcome assessment in HNC.
The aim of the study is to determine the feasibility and efficacy of moderate weekly whole Body hyperthermia Treatment during radiochemotherapy for pre-irradiated locally or regionally recurrent head and neck squamous cell carcinomas. The Primary aim of the study is feasibility, defined as 80% of patients completing at least four applications of hyperthermia. Secondary endpoints include an increase of Tumor Perfusion by the use of hyperthermia, measured by magnetic resonance Imaging during week two of Treatment and reduction of Tumor hypoxia, measured by hypoxia specific Positron emission tomography.
To implement and evaluate a health information technology platform designed to support the management of patients with head and neck cancer in an urban, publicly-funded outpatient setting. This is an observational study; researchers will not assign specific interventions to study participants.
Nutritional supplements containing antioxidants seem to decrease toxicity associated with Radiotherapy (RT) and Chemotherapy (CT) in patients with malignant head and neck tumors. Oncoxin-Viusid® (OV) is a nutritional supplement with antioxidant, immunomodulator and antitumor effects.
Management of pharyngoesophageal stenosis (PES) in patients after head and neck cancer (HNC) treatment remains a challenge. There are some cases of strictures refractory to dilation sessions. This study aimed to evaluate the efficacy of Mitomycin C (MMC) endoscopic injection for the treatment of refractory pharyngoesophageal stenosis. Patients and methods: This is a prospective study in patients with dysphagia following head and neck cancer treatment, without evidence suggestive of tumor recurrence, and refractory to endoscopic treatment. Theses undergo endoscopic dilation of the stenotic segment with thermoplastic bougies, followed by the injection of MMC.
This study observes the clinical efficacy of combining proton SBRT with PD-1 blockade immunotherapy in both the locoregionally recurrent and metastatic settings.
This is a non-randomized, phase II, open label study of radiotherapy concurrent with Apatinib Mesylate after surgery in patients with advanced head and neck soft tissue and bone sarcomas. The primary purpose of this study is to evaluate the efficacy and safety of Apatinib Mesylate in patients with head and neck soft tissue and bone sarcomas.
It is still unclear if Lymph Node Yield (LNY) and Lymph Node Ratio (LNR) may have a prognostic role in patients affected by carcinoma of the oral cavity and the oropharynx. Only retrospective studies are available. For this reason, this prospective, multi center, observational study should provide indications in this regard. Proper stratification by patients characteristics will allow to understand if LNY and LNR may enter in the future TNM staging system
Background: Locally advanced head and neck cancer (HNC) is a challenge as, in spite of initial good control with chemoradiation, the majority of patients fails systemically. In the last 2 years, immune check points inhibitors (mainly Programmed Death (PD)-1 inhibitors) were approved for metastatic/recurrent HNC. The favorable toxicity profile and durable responses was the main benefit of these drugs along the scope of cancers they were approved for. Aim of the study and methods: This will be a phase II non-randomized trial to define safety and efficacy of combining the PD-1 inhibitor pembrolizumab given concomitantly with the usual standard of care chemoradiation/bioradiation for locally advanced non-nasopharyngeal HNC. Primary end point will be assessment of toxicity and tolerability while the secondary end points will be response rates (RR) and progression free survival (PFS)
