Filter by:Hypothesis: Cetuximab, an anti-EGFR antibody, is used with radiotherapy in the treatment of locally advanced and inoperable upper aerodigestive tract cancers. Actually, no predictive biomarkers of Cetuximab antitumor activity are known in this setting. It has been shown recently that FCγRIIIA and FCγRIIA receptor polymorphisms played a role in antitumor activity of trastuzumab and cetuximab. The investigators therefore hypothesized that FCγRIIIA and FCγRIIA receptor polymorphisms may play a predictive role in Cetuximab effectiveness in upper aerodigestive tract cancers with recurrence or metastatic disease that make them inaccessible to loco regional treatment.
Chemo-radiotherapy (CRT) is currently the cornerstone in the management of locoregional advanced head and neck cancer (HNC). Optimization of the quality of RT is therefore an important issue, if the investigators want to improve the therapeutic index in HNC. This could be achieved by a more accurate definition of the tumor volume and by identification of radioresistant volumes within the tumor. Recent literature puts in this regard the incorporation of functional imaging (FI) in the RT treatment planning forward as a promising tool. FI modalities provide an outstanding contrast between tumor and surrounding tissues. This is in contrast to anatomical imaging. Using anatomical imaging in RT treatment planning, sufficient margins need to be placed around the tumor volume in order to compensate for geometric uncertainties. Consequently many surrounding functional structures receive high doses of irradiation, resulting in side effects. It is expected that, using FI in RT treatment planning will make these margins smaller or even unnecessary, which will result in less irradiation of the surrounding tissues. So far only one study has reported a comparison between tumor volume on anatomical (CT and MRI) and FI (PET-CT) modalities with pathological tumor volume. This study showed indeed that the tumor volumes delineated on PET-CT correlated more to tumor volumes defined by pathology and were significantly smaller. Furthermore, FI provides us with a deeper insight in the tumor's underlying biological activity and microstructure. These techniques can thus help to identify radioresistant subvolumes which might benefit from treatment intensification. A validation of these FI modalities with pathology is necessary to investigate their true power in tumor delineation and in the identification of radioresistant subvolumes.
This prospective study aimed to evaluate the usefulness of squamous cell carcinoma antigen (SCCA) as a clinical marker of sinonasal inverted papilloma (IP). The potential benefit of SCCA in the diagnosis of unilateral nasal pathology and as a marker of hidden recurrence was evaluated as well. Blood samples from patients with sinonasal IP were examined to determine serum SCCA levels before surgery, the day after surgery, and every 6 months during follow-up. Preoperative and postoperative levels of SCCA were compared.
This randomized phase II trial studies how well giving afatinib after chemoradiation and surgery works in treating patients with stage III-IV squamous cell carcinoma of the head and neck at high-risk of recurrence. Afatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
Phase 2 evaluation of capecitabine in patients with advanced or recurrent squamous cell carcinoma of the skin.
To study the safety and efficacy of the combination of LJM716 and BYL719 against currently available treatments of physician's choice in previously treated esophageal squamous cell carcinoma patients.
The purpose of this study is to determine if low-dose radiation therapy and the chemotherapy drug paclitaxel is effective in treating head and neck cancer that has returned after treatment with standard radiation therapy alone, but cannot be removed by surgery. The overall total dose received of both the chemotherapy and radiation therapy will be less than that typically given as standard of care; however, the Food and Drug Administration (FDA) has not evaluated the safety and effectiveness of this combination therapy. In addition, this study will gather information about the effects of radiation therapy and chemotherapy on subject's overall quality of life.
The purpose of this study is to learn more about the outcomes of treatment of throat and voice box cancers using transoral robotic surgery (TORS). TORS is a relatively new option involving the use of the da Vinci surgical robot to remove these cancers through the mouth.
This pilot randomized phase I/II trial studies the side effects and best dose of PI3K inhibitor BKM120 when given together with cetuximab and to see how well it works in treating patients with recurrent or metastatic head and neck cancer. PI3K inhibitor BKM120 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as cetuximab, can block tumor growth in different ways. Some block the ability of tumors to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Giving PI3K inhibitor BKM120 together with cetuximab may kill more tumor cells
This phase II/III trial studies how well radiation therapy works when given together with cisplatin, docetaxel, cetuximab, and/or atezolizumab after surgery in treating patients with high-risk stage III-IV head and neck cancer the begins in the thin, flat cells (squamous cell). Specialized radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. Drugs used in chemotherapy, such as cisplatin and docetaxel, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Cetuximab is a monoclonal antibody that may interfere with the ability of tumor cells to grow and spread. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. The purpose of this study is to compare the usual treatment (radiation therapy with cisplatin chemotherapy) to using radiation therapy with docetaxel and cetuximab chemotherapy, and using the usual treatment plus an immunotherapy drug, atezolizumab.
