Filter by: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.
This is a study of Nivolumab in combination with experimental medication BMS-986205 compared to the standard of care EXTREME regimen in head and neck cancer that has come back after initial treatment, or is widespread when first diagnosed.
Examining if the use of serial pHRMi to identify biomechanical changes in the swallow function of HNC patients treated with radiotherapy.
Surgical resection is the only option for cure for patients with a resectable tumor located at the head of the pancreas. At the time of diagnosis, these patients often suffer from jaundice. Studies have suggested, that jaundice might increase the risk of developing a serious postoperative complication. Preoperative biliary drainage is widely used, because it is considered to improve the surgical outcome and reduce the amount of postoperative complications. There are also studies that suggest the opposite. In these studies the overall complication rate with patients who underwent preoperative biliary drainage was higher than in the patients who were operated right away. A significant amount of these complications were related to the biliary drainage process itself. However, preoperative biliary decompression is widely used in many centers as many surgical centers don't possess the needed resources to arrange early surgery. The benefits and risks of this procedure remain unclear. This multicenter trial aims to compare the surgical outcome and the rate of serious complications in patients who proceed directly to early surgery and patients who have preoperative biliary drainage.
Wound complications, such as salivary-cutaneous fistulas and skin necrosis, result in significant patient morbidity and death. Head and neck wounds are complicated because of multiple tissue layers, critical structures and variable vascularity. When vascularity is compromised, wounds do not heal and can lead to life threatening haemorrhage or morbid infections. The field of microsurgical reconstruction has developed and expanded over the last 20 years to specifically ameliorate these issues. The challenge is that the vascularity of the microsurgical transplant or the recipient tissue bed can have areas of decreased vascularity that cannot be appreciated by the surgeon's intraoperative exam alone. Surgeons would be able to make better decisions with respect to the vascularity if there was an imaging technique that could indicate the vascular supply of the tissues undergoing surgical reconstruction. Laser-assisted indocyanine green fluorescent dye angiography (LA-ICG) using the SPY System (Novadaq Technologies Inc., Richmond, British Columbia, Canada) is an intraoperative vascular imaging technique that improves the ability of a surgeon to assess the vascular supply in the surgical bed. This tool, which is approved by Health Canada for reconstructive surgery, has been used extensively in breast reconstruction and gastrointestinal procedures with encouraging results. The ability to address ischemic tissues intraoperatively could potentially decrease the rate of devastating wound complications in head and neck surgery patients. The objective of this observational study is to assess the effectiveness of LA-ICG in head and neck reconstructive procedures to reduce the rate of skin necrosis and fistula.
This randomized clinical trial studies how well Nestle Impact Advanced Recovery works in improving surgery recovery in patients with head and neck cancer. Adding a nutritional supplement, such as Nestle Impact Advanced Recovery to a regular diet before and after head and neck cancer surgery may help to decrease the number of wound complications after surgery.
This is a research study to test the combination of two drugs, pembrolizumab and epacadostat with the goal of benefiting subjects with head and neck cancers where prior or ongoing regimens with a PD-1 or PD-L1 inhibitor for the treatment of advanced head and neck cancer after platinum failure.
This is a Phase 1 Window of Opportunity study to evaluate the pharmacodynamic and immune effects of pre-operative therapy with Mocetinostat and Durvalumab on patients with squamous cell carcinoma of the oral cavity.
The prospective trial is to describe the quality of life and psychological effects in patients with head and neck tumor receiving curative intent treatment
Given the lack of evidence for the benefit of particle therapy in relevant cases, he investigators proposed an in silico trial to investigate the dosimetric effect of contour changes for OAR as well as tumor during chemoradiation in H&N patients. Photon and proton-therapy will be compared based on dosimetric data on 7 time points during treatment combined with plan robustness. In that way the investigators will be able to assess and compare the optimal timing for replanning for photon and proton therapy. A database of the University of Pennsylvania (Upenn) consists of 10 patients with head and neck tumors treated with chemo-radiation. Contrast-enhanced CT scans were acquired prior and during RT (T1-T7)
