Filter by:Exploratory study to evaluate the effect and safety of the use of Ocoxin® oral solution on the quality of life of paediatric patients with advanced stage solid tumours.
The goal of this observational study is to evaluate disease-free survival (DFS) in patients with malignant gliomas undergoing neurosurgical procedures using 5-aminolevulinic acid (5-ALA)-based photodynamic therapy
Cancer is a frequent disease considering that one person out of three will be confronted with it in their lifetime. Cancer patients often express complaints related to cognitive impairment as an outcome of their oncological treatment. These cognitive disorders have a significant impact on the patient's and their carer's quality of life. Therefore, it appears necessary to have a reliable, quick and simple tool in order to detect cognitive impairment. The rationale of this study relies on 3 main points : - The cognitive complaint frequently reported by cancer patients - The difficulty in reliably demonstrating the cause of this complaint through conventional neuropsychological tests - The interest of cognitive processing speed as an indicator of cognitive dysfunction The primary objective of the study is to evaluate a potential variation of cognitive processing speed at the Saint-Louis Lille Battery (SSLIB) between the beginning and during (4 months after the beginning) the oncological treatment of adults with breast cancer or colon cancer.
This phase I trial studies the impact of taking drugs (agents) that target altered brain metabolism following standard of care brain radiotherapy. Radiotherapy uses high energy x-rays, particles, or radioactive seeds to kill cancer cells and shrink tumors. However, radiotherapy can also cause harmful effects to normal brain functioning. One drug, called anhydrous enol-oxaloacetate (AEO), has previously been studied in ischemic stroke, Alzheimer's disease, Parkinson's disease, and glioma. Drugs such as AEO may help preserve or restore healthy brain function after brain radiotherapy compared to the standard practice which consists of no drugs.
This is a multi-center, prospective, self-controlled, diagnostic accuracy comparative study of Artificial Intelligence Diagnostic System for Surgical Neuropathology. The investigators will compare the diagnostic efficiency of Artificial Intelligence with that of practicing pathologists, and suppose that the diagnostic efficiency of artificial intelligence in prospective clinical data is no less than that of pathologists.
Surgery is the cornerstone treatment of most pediatric CNS tumors, including astrocytomas, ependymomas, medulloblastomas, and many other pathologies. In most pediatric CNS tumors, the aim of surgery is maximal tumor resection, while preserving neurological function. Extent of tumor residual has been shown to be a major prognostic factor for progression free survival (PFS), and survival in several malignant and low-grade tumors such as medulloblastomas, ependymomas, and astrocytic tumors. 5-aminolevulinic acid (5-ALA) has been shown to be valuable in intraoperative marking of various cancers. Following oral admission, during surgery, the tumor tissue is illuminated by blue light. Tumor cells tend to metabolize 5-ALA to a porphyrin named protoporhyrin IX (PpIX). PpIX reacts with the blue light and emits a pinky color (- fluorescence). This enables the surgeon to better identify tumor cells and perform a more extensive resection. Over recent years, many studies have proven the efficacy using 5-ALA for resecting various intracranial and spinal tumors, thus achieving a better tumor control. In the suggested study, we propose using the same technique for various pediatric central nervous system tumors. We will focus on the correlation between various pathologies and the fluorescence, trying to deduce the role of 5-ALA in resection of specific pathologies. Also, we will study the safety of 5-ALA use in the pediatric population.
The investigators hypothesize that the rate of radiologically complete resections of contrast-enhancing brain tumors following surgeries aided by use of 5-ALA induced fluorescence guidance and use of an intraoperative ultra-low field MRI is higher compared to surgeries aided by 5-ALA induced fluorescene alone.
