Active clinical trials for "Carcinoma"

Merkel cell carcinoma, advanced basal cell carcinoma requiring systemic treatment, and cutaneous adnexal carcinomas are 3 types of rare skin cancers for which much remains unknown in terms of natural behavior, prognosis, treatment and outcomes. CARADERM is a French prospective national cohort enrolling patients with either one of these 3 tumor types, whose objectives are : to provide epidemiological, clinical and socio-economic characteristics of patients to identify new clinical or epidemiological prognostic factors for these rare cancers to evaluate the impact of various treatments on outcomes

This study will investigate the tumor-associated vasculature of patients with peritoneal carcinomatosis, or cancer that spreads along the inner abdominal lining. The investigators will use a technology known as intravital microscopy (IVM) in order to visualize in real-time the tumor-associated vessels of peritoneal disease. The IVM observations may determine if an individual patient's tumor vessels would be amenable to receiving systemic therapy, based on the functionality of the vessels.

Hepatocellular carcinoma (HCC) recurs in up to 60% of patients who undergo resection. Circulating tumor cells (CTC) have been advocated as promotors of the recurrence. However, their role as prognostic markers in the surgical setting is unclear. The aim of the present study has been to assess the association between CTC from peripheral blood samples and the risk of recurrence after surgery. Patients with a first diagnosis of HCC, no previous treatment for this condition, no other oncological history, and BCLC stage 0-A-B will be enrolled in 2 centers. Patients will undergo to serial liquid biopsies (i.e., a 15ml peripheral blood sample on each time point) at day 0-30-90-180-365 after surgery. After isolation of peripheral blood mononucleate cells, CTC will be detected by FACSymphony™ and subsequently the following markers will be identified: EpCAM, N-cadherin (N-cad) and CD90. Epithelial-mesenchymal transition (EMT) will be analyzed by an index estimated as the ratio between the number of EpCAM+/N-cad- and EpCAM+/N-cad+ cells (EMT Index). Patients will be divided according to the recurrence status.

The primary goal of this study is to examine whether recurrence of HPV-associated OPSCC can be predicted by two factors: 1) mutations in genes called TRAF3 and CYLD, and 2) measurements of circulating HPV DNA in blood plasma. The study will also investigate whether HPV integration is associated with TRAF3 and CYLD mutations, and whether recurrence prediction improves when looking at HPV integration along with TRAF3 and CYLD mutations.

The purpose of the study is to identify bacterial and fungal microbiome associated with calcium oxalate (CO) urolithiasis and renal cell carcinoma (RCC).

The role of gut microbiota in anastomosis insufficiency in patients operated for colorectal cancer and for peritoneal carcinomatosis is going to be investigated. This is a pilot study.

MOBILE2 is a randomized controlled trial comparing mechanical and oral antibiotic bowel preparation to mechanical bowel preparation only in patients undergoing anterior rectal resection with primary anastomosis. Primary endpoint is Comprehensive Complication Index within 30 days from surgery.

How epigenetic deregulation affects gene expression patterns in subclones of the same tumor is poorly known. Peritoneal Carcinomatosis (PC) is a condition in which multiple metastases of the same abdominal tumor develop in the peritoneal cavity and intra-peritoneal organs, thus defining different ecosystems of the same cancer. PITCHER addresses the variations in epigenetically regulated gene expression between different subclones of PC in relation with cell mechanoresponses, providing insights on how cancer epigenetic landscapes evolve under environmental pressures and on strategies used by cancer cells to adapt to the transition from one ecosystem to the other. PITCHER is a network of 10 teams from Lyon, Grenoble and Marseille, based on data and specimen collection of patients who have undergone a surgery for a peritoneal carcinomatosis of ovarian or colorectal origin. PC lesions and eventually matched specimens of primary tumors will be collected in the same patients at the time of the surgery or eventually retrieved from already existing samples. Epigenetic landscapes will be analyzed by a bioinformatics pipeline combining exome sequencing, transcriptome and methylome to identify "epigenetic hotspots", and their variations across lesions will be evaluated. These analyses will be realized in fresh (when available) or pre-existing samples. When possible, organoid cultures and animal models will be derived from multicellular structures in peritoneal fluids and membrane, cytoskeletal and nucleoskeletal mechanoresponses will be characterized using Atomic Force Microscopy. The role of tumor axonogenesis, a process of neo-formation of axon fibers in tumors, will be addressed. Experimental studies of cell responses to therapy will be performed to derive mathematical predictive models. All components will be integrated in a systems biology map of PC.

This phase I trial studies how well fluciclovine positron emission tomography (PET)/computed tomography (CT) and PSMA PET/CT work in helping doctors understand and classify invasive lobular breast cancer in patients with invasive lobular breast cancer that is suspicious for or has spread to other places in the body (metastasized). Fluciclovine and PSMA are radiotracers used in PET/CT imaging scans that emit radiation. The PET/CT scan than picks up the radiation being released to create a picture from within the body. Information learned from this study may help researchers learn how to better identify metastatic disease in invasive lobular breast cancer patients which will impact appropriate staging.

All participants will be tested for EBV associated biomarkers, including EBNA1-IgA, VCA-IgA, BNLF2b total antibodies (P85-Ab) et al. For all male participants and P85-Ab positive female participants, EBV DNA in plasma will be tested. Screening positive participants will be followed up annually. All subjects will also be followed by record linkage to Cancer Register and Population Register.
