Active clinical trials for "Head and Neck Neoplasms"

This pilot clinical trial studies how well whole-neck computed tomography perfusion scans work in imaging patients with head and neck tumors. Diagnostic imaging procedures, such as whole-neck computed tomography perfusions scans, may provide more information about the blood supply to head and neck tumors which may help doctors plan better treatment.

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 concern squamous cell carcinomas (HNSCC) 90% of the time. Despite aggressive treatment strategies, the five-year survival rate has only marginally improved in the past decade. The prognosis is strongly dependent on initial staging. The 5-year relative survival rate is 80,3% for patients with localized disease whereas it decreases to 47.2% when regional lymph node metastasis is known, and to 32.5% when distant metastasis is known. Hence, precise cancer staging is essential as it allows clinicians to select the appropriate treatment strategies and predict the prognosis of the patients. The conventional work-up (CWU) includes physical examination, endoscopy, computed tomography (CT) and/or magnetic resonance imaging (MRI) of the head and neck to evaluate the initial local and regional HNSCC staging. Thoracic CT is recommended because the thorax is the most frequent location of remote metastasis and synchronous second cancer outside of the upper aerodigestive tract. Some authors demonstrated that 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET) had a higher sensitivity and specificity for determining the extent of the disease and was able to detect occult second primaries. Moreover 18-FDG PET-CT allows whole body assessment. This is why the use of 18-FDG PET-CT has increased significantly over the last several years. Added to initial CWU, 18-FDG PET-CT may restage HNSCC and as a result may alter the clinical management. Pre-therapeutic 18F-FDG PET/CT is recommended by guidelines to assess remote extension of locally advanced HNSCC and/or to look for synchronous cancer but is not systematically indicated, particularly for localized disease. Restaging impact on prognosis and clinical management remains poorly understood. Therefore, the objective of this study is to assess the impact of the additional information provided by 18F-FDG PET-CT on HNSCC initial staging and whether restaging modify prognosis and clinical management, whatever the CWU stage.

The aim of this study is the evaluation of the frequency of xerostomia and their management after radiotherapy in head and neck cancer. The quality of life of these patients is also analysed with European Organization for Research and Treatment of Cancer Quality of life Questionnaire H&N35 (EORTC QLQ H&N35).

Pancreatic ductal adenocarcinoma (PDAC) is a highly malignant tumor with relatively poor survival. Surgery is the first choice for the treatment of patients with early pancreatic cancer. However, the surgical approach and the extent of resection for patients with pancreatic cancer are controversial at present. The investigators optimized the procedure of standard pancreaticoduodenectomy to selective extended dissection (SED), which is based on the extra-pancreatic nerve plexus (PLX) potentially invaded by tumor. The investigators retrospectively analyzed the clinicopathological data of patients with pancreatic adenocarcinoma who underwent radical surgery in our center from 2011 to 2020. Patients who underwent standard dissection (SD) were matched 2:1 to those who underwent SED using propensity score matching (PSM). The log-rank test and cox regression model were used to analyze survival data. In addition, statistical analyses were performed for the perioperative complications, postoperative pathology and recurrence pattern.

This study will utilize Rasch analysis to study the construct validity and reliability of five shoulder-related patient-reported outcome measures in patients reporting shoulder impairment following surgery for head and neck cancer.

The purpose of this study is to investigate the role of the immune system in the response of squamous cell cancers of the head and neck to treatment that includes radiation therapy. Current research demonstrates that several natural immune cells and molecules affect the way the body's immune system interacts with a cancerous growth. Some cancers may be related to infection with a virus, such as the Human Papilloma Virus (HPV). Studying the activity of the immune system in head and neck cancers, especially cancers related to HPV infections, can provide valuable information to better understand the body's interaction with cancer cells.

Including 150 randomised patient, the studies aim is to determine whether an economisation and/or improvement in terms of operating time, drainage fluid, blood loss, time of hospitalisation can be found using an ultrasonic dissection device versus traditional surgical methods such as stitches an ligations.The study is performed for patients undergoing partial pancreatoduodenectomy.

Background: - Cancer of the mouth and throat is one of the most common cancers in Taiwan. This cancer develops over several years, beginning as white or red patches in the mouth or throat that become growths. It can also cause a condition that leads to rigidity of the cheeks. The growths can be identified when a doctor looks into a person s mouth. It is currently not clear why some people with abnormal growths progress to cancer while others do not. Researchers want to better understand why some patients with early abnormal growths get late abnormal growths. They also want to understand why some people get abnormal growths again, even after they receive treatment. Objectives: - To understand why some people with precancerous lesions in their mouth develop cancer while others do not. Eligibility: - Adults 21 years and older, some with abnormal growths in the mouth, some without any, and some with head and neck cancer. Design: Participants will visit a hospital in Taiwan 2 times. At the first visit, participants will answer questions about their health, lifestyle, and family medical history. A doctor will examine the participant s mouth and take a small piece of any growth they see. They will do this with a brush. They will also photograph the participant s mouth. Participants will also give blood and saliva samples, plus a small sample of a mouth rinse. Participants who are diagnosed with a late abnormal growth that is not cancer will return for a second visit. They will answer the same questions and undergo the same procedures as at the first study.

To look at what types of measures can be used to predict how an older person will tolerate chemoradiation treatment for head and neck cancer. This study uses surveys and a blood draw to look at the different measures.

The objective of this study is to evaluate the electromyographic activity of masseter muscle during deglutition in laryngectomized subjects.
