Filter by:This a prospective real-world navigation study using tumor DNA sequencing technology to sequence genes of previously treated and refractory gastrointestinal tumors, which are generally considered to be highly heterogeneous and complex, to screen potential molecular targeted drugs for individualized treatment. This study may provide feasibility and response information, which will be the basis for designing better randomized trials, which may change the pattern of cancer treatment. If the hypothesis is finally proved, it will help doctors and molecular biologists to choose the best drug (or combination of drugs) based on the individual oncogenomics of each patient.
Circulating tumor DNA (ctDNA) offers the possibility of accessing the tumor genome from circulating blood through a simple blood test. It is currently used for diagnostic, prognostic and predictive purposes of response or resistance to oncological treatments. These advances in ctDNA have been made possible by major developments in molecular biology techniques in recent years, as the detection of ctDNA requires very sensitive techniques such as Next Generation Sequencing (NGS). CtDNA overcomes this problem of very limiting tumor heterogeneity during a solid biopsy. All of these applications make circulating DNA an increasingly essential tool in the management of cancer patients. The studies are currently in most cases on small numbers and are retrospective. In addition, exosomes are also a biomarker of the future that can also be detected in the bloodstream . Exosomes are nanovesicles 50 to 200 nm in diameter released into the extracellular environment via the endosomal pathway by fusion with the plasma membrane. They are very informative since they transport tumor genetic material in the form of DNA, mRNA and miRNA, but also adhesion proteins, immunostimulatory molecules and cytoskeleton, enzymes and Heats shock proteins ( HSP). The aim of the ADIGYN study is to set up a large prospective cohort to assess the diagnostic, prognostic and predictive impact of ctDNA and exosomes in digestive and gynecological / breast cancers. From the circulating DNA, we characterize the ActDNA on the molecular level thanks to the study of different point mutations usually used but also of new described mutations having a therapeutic impact and the search for other genetic alterations having an impact on the therapeutic strategy (such as microsatellite instability) or the study of exosomes and their composition. To assess resistance to oncological treatments, ctDNA will be analyzed at the start of treatment, during treatment, during progression and / or relapse and also during monitoring or treatment break
Background After the emergence of Covid-19 in China, Hubei Province, the epidemic quickly spread to Europe. France was quickly hit and the Croix-Rousse hospital at the Hospices Civils de Lyon was one of the first French university hospital to receive patients infected with Sars-COV2. The predicted massive influx of patients motivated the cancellation of all elective surgical procedures planned to free hospitalization beds and to free intensive care beds. Nevertheless, patients who had to be canceled had to be properly selected to avoid a life threatening. The retained surgical indications were surgical emergencies, oncologic surgery and organ transplantation. The objective was to describe the organization of the Croix-Rousse hospital to allow the continuation of these surgical activities while limiting the exposure of patients to the Sars Cov2.
NEONEC is a single-phase, phase II study evaluating the efficacy of the 12-month neoadjuvant chemotherapy in patients with locally differentiated digestive NEC. The recommended chemotherapy is based on the current reference combination of platinum (cisplatin or carboplatin) and etoposide (VP16). For anorectal locations, radiochemotherapy is proposed to avoid the morbidity of conventional surgery. The objective of the study is to improve relapse-free survival (RFS) in NEC patients treated with neoadjuvant chemotherapy followed by surgery or chemoradiotherapy. In parallel, we will perform a prospective cohort study with patients whose diagnosis is made during surgery, who have not received neoadjuvant treatment, and who are offered an adjuvant treatment of the same type (combination of platinum and platinum salts and etoposide).
The investigators hypothesize that an early assessment of the clinical toxicity of the patient is possible via patient reported outcomes and that this information provides at least the same information level as the clinical examination of the patient made by the doctor. The early decision to prepare chemotherapy medications based on the indirect early collection of clinical information from the patient via a patient reported outcome should help minimize the number of chemotherapy medications destroyed.
Hospitalization, for cancer patients, exposes to a risk of undernutrition which has the effect of significantly increasing infections, pressure ulcers, muscle wasting, loss of autonomy, impaired function and delayed healing. All of these factors contribute to increase the length of stay in hospital, thus lengthening the spiral of undernutrition, which has serious consequences for the patient welbeing, health establishments and public health. Undernutrition has been the subject of many studies over the last twenty years, that outline that an adequate nutritional management exerts a direct effect on the reduction of comorbidities and duration of hospitalization. However, there are periods, in the preoperative course of care, where nutritional and phisical care are not realized in the current clinical practice whereas they could be done, for example, between the diagnosis and the consultation of anesthesia, between the anesthesia consultation and the surgical procedure and the end of hospitalization of the patient. Current management is usually limited to the period of hospitalization which tends to be reduced. This situation is reinforced by the absence of relays at home, dietary consultations being not reimbursed by French health insurance. Moreover, a preliminary survey, conducted in 2012 during the pre-operative outpatient anesthesia consultation, shows that 26% of patients are already clinically malnourished, with 16.5 % of them who have lost more than 10% of their weight.
There are various techniques to obtain tissue samples by using fine needle guided by endoscopic ultrasound (EUS). These techniques attempt to obtain the most adequate material with the best quantity and quality for analysis. Currently studies that compare the results concerning capillary technique versus wet technique are not available. In this sense, the authors consider necessary to explore both techniques documenting the results that can define which could be the best method so that it can routinely be used in cases of digestive neoplasia.
The BCB is a tool: - for research in analytical and public health epidemiology, biological research and for the development of data useful for clinical research and therapeutic trials; - to help scientists understand and explain phenomena ranging from the interaction of molecules to the whole metabolism of the organism in normal and pathological situations; - to identify potential strategies for prevention, diagnosis, management and analysis of cancer subtypes. The creation of a broad clinical and biological prospective base dedicated to different types of cancer is essential for the development of such projects.
Current curative treatment of digestive peritoneal carcinomatosis consists of complete cytoreduction surgery associated with intraperitoneal chemotherapy. This treatment has important limits: a high morbimortality and the impossibility of repeating the sessions. The majority of patients are therefore treated with systemic chemotherapy, which despite its progress, remains palliative. Pressurized Intraperitoneal aerosol chemotherapy (PIPAC) has many advantages: under laparoscopy, low morbidity, good intratumoral penetration of cytotoxics, possibility of repeating the sessions and low financial cost. Therefore, the investigator propose a phase 1 study, in colorectal and stomach cancer, with oxaliplatin doses escalation in Pressurized Intraperitoneal aerosol chemotherapy. It would allow a better tumor response, with potentially few risks and thus improve survival in patients with digestive peritoneal carcinoses, increasing access to cytoreductive surgery.
Since the early 1990s, evidence-based medicine has played an increasingly important role in decision-making for the treatment of patients with cancer. The highest level of evidence is attributed to the results of randomized comparative studies, and the public health authorities require proof from randomized therapeutic trials before authorizing the use of new treatments. Patients included in therapeutic trials benefit either from the best current treatment (control group) or from a treatment supposed to present a better or similar efficacy, together with an extremely rigorous surveillance protocol. Inclusion in a randomized therapeutic trial represents the optimal therapeutic strategy.In order to optimize the fight against cancer, French public health policies have led to the progressive implementation of successive nationwide "Cancer Plans" since 2003. One of the objectives is to increase the proportion of patients included in clinical research trials. Thus, the fraction enrolled in France has progressively increased but remained low at around 8% in 2010. The current 2014-2019 plan aims to expand inclusion to 50,000 patients per year. In a context of socio-economic inequalities that concern resources, residence and access to services, identifying factors that determine inclusion in trials will in turn highlight the reasons for non-inclusion. The aim of this study was to determine, at a population level, the influence of demographic characteristics and socio-economic status of patients with digestive cancer on inclusion in a clinical trial. Between 2004 and 2010, 4632 patients were recorded by the Burgundy Digestive Cancer Registry. According to a balancing score, the 136 patients included in a clinical trial were matched with 272 patients who met the eligibility criteria for trials. Deprivation was measured by the ecological European deprivation index. A conditional multivariate logistic regression was performed.
