This study aimed to analyze the connectivity alterations in brain networks of LGG patients with epilepsy who take levetiracetam at short-term preoperatively.

Research purposes: To obtain the metabolic characteristics of glioma molecular imaging through a multimodal image recognition system. To determine whether molecular imaging metabolic parameters can characterize the molecular typing of glioma by analyzing the relationship between metabolic parameters and tumor subtypes To get metabolic classification based on metabolic parameters of glioma molecular imaging, and to identify the relationship between metabolic subtypes and surgical resection, radiotherapy and chemotherapy, and prognosis and further refine the molecular classification of glioma. Research Background: Glioma is the most common primary intracranial malignant tumor, accounting for 80% of central nervous system malignant tumors. It is highly invasive, with a surgical recurrence rate of up to 90%. The prognosis is extremely poor, which has caused a great burden. There are different molecular subtypes of glioma with distinct molecular biological characteristics, resulting in various prognosis of patients. With the continuous development of basic and clinical research of glioma and the advent of various new drugs and treatment technologies, molecular pathological diagnosis based on the individual level of glioma patients is particularly important. Clarifying the molecular pathology type before surgery will help the clinical diagnosis and prognostic judgment of glioma, and is of great significance for the optimization of treatment options. Based on the establishment of glioma molecular typing system, the project team use noninvasive molecular imaging technology to clarify the characteristics of molecular subsets of glioma based on the tumor metabolic parameters. Through combining deep learning-based target detection and image recognition with big data analysis, it has great potential in the clinical research of glioma diagnosis, prognosis and treatment options, which could provide a scientific basis for the establishment and promotion of glioma molecular analysis and recognition system.

This study is a retrospective observational study that evaluates the rate of cardiovascular adverse events leading to hospitalization in metastatic colorectal cancer in the French county Calvados by drug exposure.

Control of cell death is frequently disrupted in cancer resulting in overgrowth of tumour cells. Caspase-8 is a key enzyme involved in controlling cell death. This study examines the importance of caspase-8 in oral cancer.

This study will be a secondary use of data, focusing on patients treated with combination therapy Obi-Clb, R-Clb or R-B, in a non-interventional, open label, national, multicenter setting. Retrospective analysis of data coming from registry database CLLEAR (www.leukemia-cell.org )that capture data on clinical and treatment practices in CLL. Data will be retrospectively analyzed.

The investigators prospectively collected the clinical data of Da Vinci robot-assisted radical gastrectomy patients conducted by the same group of physicians from October 2017 to October 2018. The learning curve of the surgery was analyzed with the moving average method and the cumulative sum analysis (CUSUM). The short-term efficacy was then validated by comparing the perioperative and pathologic outcomes of patients in the two stages of the learning curve.

Paraneoplastic neurological syndromes (PNS) are immune-mediated complications of cancer that can affect any part of the central or peripheral nervous system. PNS occurs at the intersection between immune system and the tumor, where a combination of genetical and environmental factors may play a role. Mechanisms leading to immune tolerance breakdown and autoimmunity in PNS remain largely unknown, and this reflects in an unsatisfactory repertoire of treatments available. Moreover, a better understanding of the biological mechanisms underlying PNS would allow a more precise identification of the modalities that permit PNS patients to have a better oncological prognosis than cancer patient without PNS, with obvious repercussions in clinical oncology. To this effect, an extremely innovative approach involves directly exploring the tumoral tissue of patients suffering from specific PNS via genomic and transcriptomic analysis. The study team hypothesizes that antigen ectopic expression by tumour cells may contribute to the generation of PNS. In the present study, the investigators will analyze the salient features of tumors associated with PNS, namely the histological and immune cells infiltrate characteristics, their transcriptomic profile, and mutational status of involved antigens.

Context : Colorectal cancer (CRC) mass screening has been implemented in France since 2008. Participation rates remain too low. The objective of this study is to test if the implementation of a training course focused on communication skills (whether in-person or e-learning) among general practitioners (GP) would increase the delivery of gFOBT and CRC screening participation among the target population of each participating GP. Method : Pragmatic controlled cluster randomized trial with 2 parallel groups: Control versus Educational Intervention Intervention ; six hour educational training either in person or through e-learning The Main objective: is to evaluate the effectiveness of an educational intervention teaching physicians the patient-centered approach, either in-person or through e-learning, by evaluating their patients' participation in colorectal cancer (CRC) screening for all risk categories.

Colorectal cancer (CRC) affects men and women of all racial and ethnic groups and accounts for more than 600,000 deaths per year, globally. Current treatment options may involve surgery, chemotherapy (both adjuvant and neoadjuvant), radiation therapy, and palliative care, each with trade-offs between disease management and patients' quality of life. Unfortunately, significant disparity exists in the quality of care and there is a need for standardization to ensure high-value health care for all patients. This study evaluates the introduction of a Value-Based Health Care (VBHC) patient-centered framework in CRC treatments. VBHC is an innovative approach that aims to improve health care by identifying and systematically measuring both medical and patient-reported health care outcomes and costs. By applying sets of disease-specific outcomes measurements, health care providers (HCP) can compare care strategies and make informed choices with regard to optimization of care, necessary investments and possible cost reductions. The adoption of a VBHC patient-centered approach may have a significant impact on therapeutic areas constituting a major disease and cost burden for the global health care, such as CRC. It has the potential to improve cancer care planning, monitoring, and management of patients, by promoting better communication and shared decision making by patients and HCP. A patient-reported outcome measurement (PROM) is defined as any report about a health condition and its treatment that comes directly from the patient. The use of a tailored pathway including PROMs improve both quality of life (QoL) and survival in cancer patients. Another essential requirement of VBHC approach is the outcome monitoring, to allow HCP accessing to evidence-based, simplified information on the hospital clinical practice and potentially increase health value for both patients and HCP. For patients with CRC, the International Consortium for Health Outcomes Measurement (ICHOM) developed a comprehensive patient-centered outcomes measurement set that could be used in the clinical practice to monitor patients' status. The purpose of this study is to evaluate the introduction of a VBHC approach in CRC treatments, using a validated VBHC set of clinical outcomes and PROMs, to understand which practice would be most effective in achieving patient-centered care. The underlying hypothesis is that a periodic analysis of these outcomes could increase health value for both patients and HCPs.

The study consists in a co-clinical trial by using zebrafish embryos. Specifically, an observational prospective clinical trial on patients operated of epato-biliar-pancreatic cancers and gastro-intestinal cancers undergoing a chemotherapy treatment will be run concurrently to an animal trial on zebrafish embryos xenotransplanted with patient cancer cells in order to demonstrate that zebrafish model is able to predict the therapeutic regimen with the best efficacy for each patient.
