Active clinical trials for "Carcinoma, Squamous Cell"

To describe the clinical response rate in two groups (Docetaxel plus cisplatin plus 5-FU, versus Cisplatin plus 5-FU) after 3 cycle of neoadjuvant chemotherapy.

This is prospective research study which will include patients with recurrent or metastatic squamous cell carcinoma of the head and neck, esophagus and anal canal starting on first-line platinum based chemotherapy or any line of immunotherapy treatment.This study aims to characterize the dynamic changes in genomic, epigenetic, immune profiling and imaging data during treatment with systemic therapy. Patients will have archived tumor samples requested as well as blood samples collected at up to four time points to analyze these changes. Imaging data will be derived from patients' routine CT scans before and after treatment.

This research study will include patients with high risk locally advanced head and neck squamous cell carcinoma (LA-HNSCC) of the oral cavity, oropharynx, hypopharynx or larynx and patients that are starting on standard definitive treatment. Patients with both stage III HPV positive and stage III HPV negative will be included. In this study, we aim to evaluate feasibility of ctDNA and/or HPV DNA detection in real time in high-risk LA-HNSCC.

Nivolumab is an antibody (a type of human protein) that is designed to boost your body's immune system. It does this by allowing immune cells to grow and fight the cancer. Nivolumab has been approved by the FDA for the treatment of melanoma (a form of skin cancer) and lung cancer. It is currently under study for the treatment of head and neck squamous cell cancer.

The investigators hypothesize that treatment adaptation to biological and anatomical changes, occurring during treatment, can increase the chance of cure at minimized or equal radiation-induced toxicity in head and neck cancer patients. This trial compares standard intensity-modulated radiotherapy (IMRT), using only pre-treatment planning 18F-2-fluoro-2-deoxy-D-glucose positron emission tomography to adaptive 18F-2-fluoro-2-deoxy-D-glucose positron emission tomography voxel intensity based IMRT or volumetric-modulated arc therapy (VMAT) using repetitive per-treatment planning 18F-2-fluoro-2-deoxy-D-glucose positron emission tomography for head and neck cancer.

Patients were eligible if they had biopsy proven, previously untreated T3 with fixed cord involvement squamous cell carcinoma of the pyriform sinus. The study compare conventional radiotherapy with concurrent cisplatin to induction chemotherapy with cisplatin fluorouracil followed by conventional radiotherapy. The primary end point was the preservation of the larynx. The secondary end points included toxicity, causes of death and survival rates.

A consistent finding in many studies in patients with operable esophageal and gastro-esophageal junction (GEJ) cancer is that response to preoperative therapy, particularly the absence of residual disease in the surgical specimen, is an indicator of better disease-free and overall survival. Therefore in the investigators trial the investigators will evaluate the pathologic response of panitumumab in combination with neoadjuvant chemoradiation as first line treatment of operable adenocarcinomas, undifferentiated or squamous cell carcinomas of the esophagus.

Treatment is based on radiochemotherapy for locally advanced tumours. The objective of treatment is to provide a cure without resorting to abdominoperineal amputation, while preserving sphincter function. The prognosis is mainly related to tumour size and lymph node invasion. The large majority of patients do not show any spread remote from the tumour at the time of diagnosis (2). Recurrences are mainly of a local/regional nature and require abdominoperineal amputation. This type of intervention is not always possible or complete, which then gives rise to the particularly distressing risk of local progression, with survival at 3 years of approximately 30% (3). It is therefore very important to achieve a complete and permanent tumour response from initial treatment with radiochemotherapy. Furthermore, the use of an anti-EGFR antibody in combination with exclusive radiotherapy in ENT cancer was able to increase recurrence-free survival and overall survival in these patients. These data are in favour of the use of a combination of chemotherapy and anti-EGFR antibodies in epidermoid cancer of the anus.

The purpose of the study is to compare time to progression and overall survival after treatment with Taxotere plus cisplatin versus cisplatin plus 5-FU (PF treatment group) in the first line treatment of patients with recurrent and/or metastatic squamous cell carcinoma of the head and neck.

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.
