Filter by:This pilot phase I trial aims to investigate the efficacy and safety of high- and low-dose radiotherapy combined with programmed cell death-1 (PD-1) inhibitors in microsatellite stable (MSS) metastatic colorectal cancer (mCRC) that have failed second-line immunotherapy or above.
Background: Primary or secondary brain tumors (metastases) remain associated with a very poor prognosis linked to significant therapeutic resistance. Thus, glioblastoma, which is the most common and aggressive primary brain tumor in adults, is associated with inevitable relapses within 7 to 10 months and median survival of approximately 12 to 14 months. At the same time, brain metastases are increasingly increasing following better systemic control of other metastatic sites and improvement in detection methods. However, they remain resistant to the latest therapeutic innovations such as immunotherapies or targeted therapies. In this context, innovative strategies are necessary to identify new therapeutic targets and implement new treatments to overcome resistance phenomena in the clinic. Objective: Our goal will be to generate tumoroids and stem-like cell lines (PDX) from patient tumor samples. Methods: We will establish tumor tumoroids and stem cell lines from patient samples. These preclinical models will allow us to test a large number of drugs, quickly and efficiently thanks to models as close as possible to patient tumors and limiting the use of animal models (3R). Overall, this project should enable major advances in the treatment of glioblastoma and brain metastases and enable the rapid testing of new molecules in clinical trials thanks to the homology of our models with our patients' diseases.
The aim of the study is to establish a multi-center, retrospective database for patients with intramedullary spinal cord metastases (ISCM) and analyse the functional outcome in surgically treated ISCM patients. The hypothesis is that the surgical treatment of selected ISCM patients does not lead to persistent morbidity and does not increase mortality, compared to patients that are treated non-operatively. Secondary objectives are to assess pre- to postoperative neurological deficits, ambulatory status, and overall survival of surgically treated ISCM patients. The investigators intend to include a control cohort of patients with ISCM from participating centers, who underwent non-surgical oncological treatment (radiotherapy with or without chemotherapy). This control cohort of patients will be used to match patients with and without surgical treatment. Primary endpoint (analysed in surgically treated ISCM patients): Functional outcome at 90 days after treatment initiation, measured by the modified McCormick Scale. This is a score for grading of neurological function in spinal cord conditions. The McCormick scale ranges from Grade I (neurologically intact) to grade V (paraplegic or quadriplegic). The McCormick scale is suitable for our retrospective study because of its good reproducibility and comparability. Secondary endpoints (analysed in surgically treated ISCM patients and analysed in matched patients with and without surgical treatment): - Functional outcome by the McCormick scale and the modified Japanese Orthopaedic Association scale (mJOA) at 6 and 12 months. This is a score evaluating motor function of upper and lower extremities, sensory function of upper extremities and sphincter function / voidance. The mJOA ranges from 0 - 18 points, with higher score values representing better functional outcome. The minimum clinically important difference of the mJOA is 1-2 points, and scores lower than 14 indicate moderate myelopathy, scores lower than 11 indicate severe myelopathy. - Ambulatory status and continence at 90 days, 6 & 12 months (determined by mJOA subscores) - Neurological outcome, measured by American Spinal Cord Injury Association (ASIA) - Impairment Scale at 90 days, 6 and 12 months - Rate & type of complications at 90 days after treatment according to The Novel Therapy - Disability-Neurology Grade (TDN grade)16 - Overall survival (in days)
The management of brain metastases has evolvedĖ rapidly in recent years. It is estimated that 20% to 40% of cancer patients will develop brain metastases (BM) during the course of their disease. Whole-brain radiotherapy has long been the first-line treatment for brain metastases. However, large-scale international clinical trials conducted over the past decade have established stereotactic radiotherapy (SR) as the treatment of choice for the management of brain metastases (BM). However, even though the method of radiation delivery has evolved considerably, the problem of monitoring and managing brain metastases remains unresolved. This study therefore has several focuses: 1. Evaluation of the benefit of early remnographic assessment (6 weeks): impact on recurrence-free survival and overall survival. 2. Evaluation of a diagnostic approach to radionecrosis: complementarity of DOPA PET and multimodal MRI. 3. The benefits of longitudinal remnographic monitoring with the development of segmentation and automated follow-up tools
Cerebrospinal fluid was obtained from the cerebrospinal cavity of non-small cell lung cancer patients with central nervous system metastasis, blood was obtained from veins, and metastatic lung cancer tumor tissue was obtained from surgically resected brain tumors or meningeal tumors. Then comprehensively analyze the exosomes contained in the aforementioned samples, and compare and analyze the clinical data of the patients, so as to explore whether the cancer cell-related substances contained in the cerebrospinal fluid, blood and tumor tissue can be used to predict lung cancer metastasis and Bioindicators of treatment effect.
The goal of this observational study is to make us more aware of the short and long-term outcomes for women having an uncomplicated healing process after a rupture or birth cut in the perineum after giving birth in relation to a healing process with a dehisced wound treated with conservative management or secondary suturing. Participants will be asked to do - A gynecological examination at one month after birth and 9-12 months after birth. - Have a picture taken of the healing process - Answer a questionnaire at one month, three months, and 9-12 months after birth
A previous study of investigators established a risk scoring model for the occurrence of postoperative hepatic metastases in patients who underwent curative gastrectomy directly without neoadjuvant therapy. In order to further validate the clinical applicability of abovementioned model, investigators designed this prospective study, which also included patients who received neoadjuvant therapy before surgery, with the aim of exploring the applicability of the risk scoring model to this group of patients.
It has well accepted that tumor angiogenesis present aberrant vascular architecture and functional abnormalities, which is associated with tumorigenesis, tumor propagation and progression. By locating, separating and tracking microbubbles, the recently introduced and upgraded Ultrasound Localization Microscopy (ULM) surpassed classical wave diffraction limit. However, the acquisition of structural and functional parameters of microcirculation in vivo for ULM is still confined by the compromise between the resolution and penetration depth. The relatively long acquisition time induced the difficulty of motion correction potentially, which hampers the preclinical to clinical application in organs with distinct tissue motion such as the liver. Therefore, we take the lead in studying human liver lesion microvasculature, which remains a challenge for noninvasive, quantitative and functional intravital imaging especially due to its deep-seated location and strong motion. We developed a Super-resolution Ultrasound (SR-US) imaging technique based on ULM to assess its feasibility of visualizing and quantifying microvasculature in human organs.
The purpose of this study to find out if tocilizumab can be safely infused into chest or abdominal cavities of patients with malignancy ascites (MA) or malignant pleural effusions (MPE). Patients will have a total of 4 doses, one dose administered each week. Each dose will be greater than the previous one.
To determine the Maximum Tolerated Dose (MTD) of CycloSam®, Samarium-153-DOTMP (Sm-153-DOTMP), a radiopharmaceutical that delivers radiation to the bone when injected, given as a tandemly administered pair of doses to subjects with one or more solid tumor(s) in the bone or metastatic solid tumors to the bone that are visible on bone scan.
