Active clinical trials for "Neoplasms"

The purpose of this retrospective observational study is to evaluate the performance of the Shared Decision Making Process scale in a sample of patients who have received a decision aid about the decision to screen or not screen for breast cancer, colon cancer, prostate cancer, or lung cancer.

The leading cause of primary hyperparathyroidism (pHPT) is a solitary adenoma (89%). The treatment of pHPT is generally surgical removal of the overactive parathyroid gland(s). Since a solitary adenoma is the predominant cause, parathyroid surgery is preferably performed through a minimally invasive parathyroidectomy (MIP) in which only the suspected adenoma causing the pHPT is resected in a focused manner. To facilitate the performance of a MIP, accurate preoperative imaging is pivotal. This study aimed to analyze the diagnostic performance of 11C-choline PET/CT after prior negative or discordant first-line imaging in patients with pHPT undergoing parathyroid surgery with an optimized imaging protocol.

The purpose of this study is the development of a content-based image retrieval (CBIR) platform, where validation studies will be conducted for liver disease subtyping and hepatocellular carcinoma (HCC) phenotyping on images for use as diagnostic and prognostic markers of outcome in conjunction with large scale data registries and advanced predictive machine learning methodologies. The proposed objectives will deliver one or more fit-for-purpose non-invasive imaging-based methodologies to evaluate the presence, activity and type of HCC in clinical practice.

The Italian screening program invites the resident population aged 50-74 for Fecal Immunochemical Test (FIT) every 2 years. Subjects who test positive are referred for colonoscopy. Maximizing adenoma detection during colonoscopy is of paramount importance in the framework of an organized screening program, in which colonoscopy represent the key examination. Initial studies consistently show that Artificial iIntelligence-based systems support the endoscopist in evaluating colonoscopy images potentially increasing the identification of colonic polyps. However, the studies on AI and polyp detection performed so far are mostly focused on technical issues, are based on still images analysis or recorded video segments and includes patients with different indications for colonoscopy. At the best of our knowledge, data on the impact on AI system in adenoma detection in a FIT-based screening program are lacking. The present prospective randomized controlled trial is aimed at evaluating whether the use of an AI system increases the ADR (per patient analysis) and/or the mean number of adenomas per colonoscopy in FIT-positive subjects undergoing screening colonoscopy. Therefore Patients fulfilling the inclusion criteria are randomized (1:1) in two arms: A) patients receive standard colonoscopy (with high definition-HD endoscopes) with white light (WL) in both insertion and withdrawal phase; all polyps identified are removed and sent for histopathology examination; B) patients receive colonoscopy examinations (with HD endoscopes) equipped with an AI system (in both insertion and withdrawal phase); all polyps identified are removed and sent for histopathology examination. In the present study histopathology represents the reference standard.

Colorectal cancer (CRC) is the second most common cancer in Malaysia. Diagnosing CRC at early stage is crucial to reduce their mortality risk. To achieve this aim, CRC screening promotion intervention is deemed necessary.

The purpose of the study is to capture the utilization of nivolumab among participants with squamous cell carcinoma of the head and neck (SCCHN) since its approval, and to describe the health related quality of life (HRQoL) among participants treated with nivolumab in a real-world setting.

Case series of a retrospective study of patients operated for distal adenocarcinoma of the stomach, either by total gastrectomy or distal gastrectomy at Ibn Rochd University Hospital in Casablanca, with the analysis of outcome of patients on a follow up periode of three years and eight months.

This study examines melanoma and nonmelanoma skin cancer in people diagnosed with vitiligo compared to matched controls.

This study will present an advanced equipment of tumor nutrition diagnosis and assesment for nasopharyngeal cancer(NPC) radiotherapy patients in nutritional risk screening, evaluation, diagnosis and directing nutritional intervention, aiming to explore the advantages of the whole nutritional management in acute radiation reaction rate, completion rate of radiotherapy, nutritional status, and quality of life for NPC patients.
