Bleeding, Cardio- and Cerebrovascular Complications in Head and Neck Surgery

Head and Neck Cancer

In this retrospective registry trial, the investigators sought to assess the incidence and predictors of cardiovascular and cerebrovascular complications as well as their derivatives (acute coronary syndrome, decompensated heart failure, an episode of atrial fibrillation requiring cardiologist consultation, stroke, pulmonary embolism and venous thromboembolism) in cohort of patients undergoing head and neck surgery.

Feasibility Study of the Head and Neck Survivorship Tool: Assessment and Recommendations (HN-STAR)...

Head and Neck Cancer

This study is being done to understand how survivors of head and neck cancer think they can make HN-STAR (the Survivor Self-Assessment, the survivorship clinic experience, and the Survivorship Care Plan the best it can be. Once the investigators have your input and input from other survivors, they can make changes to HN-STAR, so that they can test this tool in a larger study. The larger study will tell them whether using HN-STAR improves the care of head and neck cancer survivors.

Prognostic Value of 18FDG PET/CT Textural Indices in HNSCC

Cancer of Head and Neck

Head and neck (HN) cancer is the sixth most common malignancy worldwide, with around 800,000 new cases and 320,000 deaths in 2015. These malignancies encompass cancers of the oral cavity, oropharynx, hypopharynx and larynx and concerned squamous cell carcinomas (SCC) 90% of the time. Despite aggressive treatment strategies, the five-year survival rate has only marginally improved in the past decade especially because of a high rate (up to 40%) of loco-regional recurrence. Moreover, two-third of local relapse and lymph node metastases occur in the first 2 years after treatment. Hence, predicting tumor response to therapy remains a real challenge in head and neck cancers. Usual prognostic factors include the tumor size, the lymph node involvement, the presence of distant metastasis, the anatomic subsite, and the human papilloma virus (HPV 16, 18) infection status. However, pre-treatment selection of patients with poor prognosis or who require intensified therapy remains difficult despite their careful evaluation. HNSCC also present a high biologic heterogeneity with hypoxic area, necrotic regions, zones of high cellular proliferation and intra-tumoral angiogenic heterogeneity. A better characterization of tumor heterogeneity could help classify patients in different risk subgroups in order to improve their therapeutic management. Pre-therapeutic 18F-fluorodeoxyglucose positron-emission tomography (FDG PET/CT) is recommended by guidelines to assess remote extension of locally advanced HNSCC and/or to look for synchronous cancer. Its prognostic significance has already been suggested and a selection of patients at risk of recurrence appears possible using different quantitative parameters. Indeed, static (SUV = Standardized Uptake Value), volumetric (MTV = Metabolic Tumor Volume, TLG = Total Lesion Glycolysis) and kinetic (RI = Retention Index) parameters were demonstrated to be independent prognostic factors in several studies. Texture analysis is currently highly studied in order to characterize tumor heterogeneity, and consists in extracting texture indices from different imaging modalities such as FDG PET/CT. Calculating texture indices relies on choosing a contouring method to delineate a tumor volume of interest and selecting several parameters such as the resampling method, matrix definitions and indices formula. Several studies conducted on small series of patients with HNSCC have showed promising results to predict survival, analyzing various cancer anatomic subsites, tumor segmentation methods and texture indices. The objective of this study is to assess the prognostic value of texture indices in a large cohort of patients with HSNCC, including any anatomic subtype and staging.

MRI for Eval Tumor & Node Response & Normal Tissue Function to Concurrent Chemo & Radiation Therapy...

Head and Neck Cancer

The investigators' goal is to incorporate advanced imaging information into the treatment planning process and assess response in tumor, nodes and non-cancerous tissues in head and neck cancer patients during and after concurrent chemotherapy and radiation therapy (chemoRT) via biophysical, biochemical and vascular imaging using magnetic resonance imaging (MRI). The investigators will recruit 30 patients with locally advanced head and neck cancer into the study. All patients will obtain an advanced MRI study at three time points: 1) before the start of chemoRT, 2) 4 weeks following the start of chemoRT, and 3) 3-4 months following completion of chemoRT. MRI scans will include a) T1, T2 and T2* imaging, b) vascular images using dynamic contrast enhanced (DCE) imaging, c) biophysical microstructure images using diffusion-weighted imaging, and d) biochemical images using MR spectroscopic imaging. The subject's response (tumor, nodes and salivary and mucosal tissues) will be evaluated using clinical outcomes. Correlations will be generated between the parameters obtained from MR images and from clinical response assessments. The purpose of this study is to assess whether advanced MR imaging techniques can be used to determine tumor and node response (i) four weeks following initiation of concurrent chemoRT and (ii) after completion of chemoRT in head and neck cancer, and to assess whether advanced MR imaging techniques can be used to predict early at-risk organ function (salivary gland and mucosal injury) as measured by salivary flow and oral mucositis to chemoradiation therapy (i) four weeks following initiation of concurrent chemoRT and (ii) after completion of chemoRT in head and neck cancer.

Observational Study on Biomarkers in Head and Neck Cancer (HNprädBio)

Head and Neck Cancer

The aim of this clinical research project is to validate the prognostic impact of potential biomarkers on loco-regional control of locally advanced head and neck cancer after definitive or adjuvant radiochemotherapy. The treatment is equal to the standard of care. Potential biomarkers from a previous retrospective study will be validated in this prospective study.

Pain in Cancer Survivors

Breast CancerColorectal Cancer3 more

The purpose of this study is to find out about the pain and quality of life of individuals who are adult cancer survivors. By quality of life, we mean how you are feeling about different aspects of your life, including your physical health, your emotional health, and your ability to carry out daily activities. We are interested in people's opinions about their quality of life, as well as the factors that affect their quality of life. In addition, learning about pain will help us to develop new services for adult cancer survivors.

Sexual Behavior in Oropharyngeal Patients Versus Head and Neck Cancer Patients, With or Without...

Head and Neck CancerOropharyngeal Cancer1 more

Primary Objectives: To determine whether high-risk sexual behaviors are more common in patients with oropharyngeal cancer than in patients with head and neck cancers of other sub-sites. To determine if high-risk sexual behaviors are more common in patients with HPV (human papillomavirus) associated head and neck cancer than those without evidence of HPV-16 infection.

Value of FLT-PET Before and During Radiotherapy in Head and Neck Tumors

Head and Neck Neoplasms

Tumor cell proliferation and repopulation contribute to resistance to radiotherapy in head and neck cancer. Up to now, this characteristic is mostly assessed using biopsies acquired during inspection under general anaesthesia before treatment. 18F-FLT-PET (positron emission tomography) is a non-invasive imaging method showing areas of active proliferation. The aim of this study is to assess the value of the functional information gained by 18F-FLT-PET for radiotherapy planning and early tumor response assessment. Prior to radiotherapy, a planning CT-scan and a 18F-FLT-PET scan are acquired. After approximately two weeks of radiotherapy a further PET scan is obtained.
