Filter by:The purpose of this study is to test the accuracy of toluidine blue in the assessment of intraoperative tumor margin after excision of oral squamous cell carcinoma(OSCC)in comparison to H&E stain on frozen section.
This is a research study to evaluate the quality of life and amount of dry mouth experienced as a result of radiotherapy in subjects who have squamous cell carcinoma of the head and neck (HN-SQCC). This study will compare the side effects experienced based on the method to plan radiotherapy, Margin Based or Robust.
Esophageal achalasia is a precancerous condition for epidermoid carcinoma; incidence and risk factors for cancer development are not defined. Incidence and risk factors for epidermoid carcinoma development in achalasia patients were investigated.
This phase II trial with a safety run-in component will evaluate whether the addition of pembrolizumab to Stereotactic Body Radiation Therapy (SBRT) re-irradiation will improve the progression-free survival for patients with recurrent or new second primary Head and Neck Squamous Cell Carcinoma (HNSCC).
Tumours continually shed DNA into the circulation, where it can be accessed. This circulating tumour DNA (ctDNA) directly reflects tumour burden and has great potential to be a sensitive biomarker for treatment recurrence. These "liquid biopsies" could give a more real-time picture of the genomic status and evolution of a tumour and can be easily assessed for measurement of different biomarkers. However, in head and neck squamous cell carcinoma (HNSCC) patients treated with primary curative radiotherapy, data regarding ctDNA kinetics and its correlation with outcome are scarce. A new or additional tool for response evaluation next to or instead of conventional imaging after treatment would be beneficial to detect recurrences in an earlier stage, thereby increasing the chances of success of salvage therapy. More importantly, an early response parameter during treatment could help to identify patients that have a good treatment response and might benefit from treatment adaptation. With this study, we aim to reveal ctDNA as an effective tool for future dose (de)-escalation trials in HNSCC.
According to the World Health Organization, oral cancer (OC) is the eighth most common cancer in the world with a five year survival rate of 50%. Oral cancer tumor cells produce biochemical substances, tumor markers, differed from healthy individuals in expression or quantitative ratio, detectable in tissues and/or body fluids. Saliva, because of its accessibility, proximity and noninvasive approach, presents an ideal tool for the research of oral cancer tumor markers. The aim of this study will be to isolate, quantify, analyze the role and describe the kinetics of diadenosine tetraphosphate (Ap4A), Squamous Cell Carcinoma associated Antigen (SCCA), Trophoblast cell surface antigen (TROP2) in patients with OC, potentially malignant disorders (PMOD) and age and sex matched control group with a clear medical history. There are number of studies published on OC tumor markers isolated mostly in serum, however the satisfactory specificity and sensitivity still hasn't been reached. Liquid chromatography-ion trap-mass spectrometry, Multiple Reaction Monitoring method (LC-IT-MS, MRM) will be developed to isolate and quantify the above mentioned tumor markers. This method has not yet been used to quantify the above mentioned salivary tumor markers. Ap4A and TROP2 have never been isolated from saliva. The aim is to develop a tumor-specific test with a satisfactory statistical sensitivity and specificity and dynamically measure the levels of tumor markers, before and immediately after therapy - surgery/radiotherapy/chemotherapy or their combination, and during regular follow-up one and two years after surgery. As another novelty, the investigators aim to determine the markers circadian rhythm. A OC tumor specific test, with satisfactory sensitivity and specificity, would enable earlier OC diagnosis, possibly before the clinical appearance, raise the survival rate of OC patients, enable early diagnosis of recurrence and/or new primary tumors and ensure better post-treatment life-quality.
This is a phase I study, which tests the safety of different doses of lenvatinib in combination with cetuximab, to see which dose is the safest in people. This study will help find out if lenvatinib and cetuximab is a safe and useful combination for treating patients with HNSCC and cSCC.
This phase I/II trial studies the side effects of durvalumab, tremelimumab and hypofractionated radiation therapy in treating patients with head and neck squamous cell carcinoma that has come back (recurrent) or that has spread to other places in the body (metastatic). Immunotherapy with monoclonal antibodies, such as durvalumab and tremelimumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Hypofractionated radiation therapy delivers higher doses of radiation therapy over a shorter period of time and may kill more tumor cells and have fewer side effects. Giving durvalumab, tremelimumab, and hypofractionated radiation therapy may work better in treating patients with recurrent or metastatic head and neck squamous cell carcinoma.
This phase II trial studies how well intensity-modulated radiotherapy and nivolumab work together in treating patients with head and neck squamous cell cancer that has come back. Intensity-modulation radiation therapy uses varying intensities of radiation beams to kill cancer cells and shrink tumors, thereby reducing the damage to nearby healthy tissue. Monoclonal antibodies, such as nivolumab, may interfere with the ability of tumor cells to grow and spread. Giving intensity-modulated radiation therapy and nivolumab may work better at treating head and neck squamous cell cancer.
Phase III randomized trial to compare the efficacy in terms of overall survival of two follow-up strategies (conventional versus intensive) among smokers and/or alcohol drinkers patients, older than 35 year, in complete remission 2-4 months after treatment of head and neck squamous cell carcinoma Patients will be randomized after the post-treatment check-up (clinical examination and reference imaging including PET-CT for patients ≥ N2) performed 2 to 4 months after the end of treatment. The randomization ratio is 1:1.
