Active clinical trials for "Peritoneal Neoplasms"

This phase I/IIa trial studies the side effects and best dose of a type of specialized immune cell (natural killer cell-like cytotoxic T-lymphocytes (CTLs) (nCTLs) and how well they work when given with a vaccine (alpha-type-1 polarized dendritic cells) in treating patients with stage II-IV ovarian, fallopian tube, or primary peritoneal cancer. nCTLs are immune cells that are isolated from each patient?s blood and "taught" in the laboratory how to recognize and eliminate tumor cells. These "educated" immune cells are then given back to the patient. An alpha-type-1 polarized dendritic cell vaccine is another population of "educated" immune cells that work to support the infused nCTLs. Giving nCTLS with a dendritic cell vaccine may work better in treating patients with ovarian, fallopian tube, or primary peritoneal cancer.

A Clinical and Biological Database will provide to the scientific community a collection of blood and tissues with clinical datas to improve knowledge about cancer and help to develope new cancer treatments. This database is specific to epithetial ovarian cancer, Fallopian tube cancer and Primitive peritoneal cancer.

Colorectal cancer is the third most common cancer in men and second in women. It represent 345'346 new cases per year in Europe and 134'349 in the United States of America. The peritoneal cavity is the second most frequent site, after liver, for colorectal cancer relapse.Peritoneal carcinomatosis (PC) is found in approximately 5 % of patients diagnosed with colorectal cancer and 24% of patients with synchronous metastasis at the time of diagnosis. Eight percent of colorectal cancer patient will develop PC during the course of their disease . Currently systemic chemotherapy is the standard of care for the treatment of unresectable peritoneal carcinomatosis from colorectal cancer with a median survival rate of 16.3 months Peritoneal carcinomatosis has a poor response to systemic chemotherapy due to a weak penetration of agents into the peritoneum. A new approach of intraperitoneal carcinomatosis is now developed: Pressurized intraperitoneal aerosol chemotherapy (PIPAC) is used to deliver intraperitoneal chemotherapy. It enhances the effect of chemotherapy because of the physical properties of aerosol and pressure. PIPAC is a safe with a 23% morbidity and tolerated technic that is now well described. We want to conduct a study to prove or infirm the superiority of PIPAC associated with systemic chemotherapy compare to systemic chemotherapy alone in peritoneal carcinomatosis from colorectal cancer

This is a two-center open-label non-randomized proof of principle study consisting of a dose-finding part (phase I) and phase II study with Simon two-stage design investigating the anti-tumor activity of the combination of capecitabine and galunisertib in patients with colorectal cancer with peritoneal metastases.

The aim of this study is to identify biomarkers of disease recurrence and prognosis to optimize patient selection for treatment with cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC), and through animal models to explore different treatment strategies for peritoneal surface malignancies (PSM).

This study is an exploratory, single-center, prospective single-arm study to explore the efficacy of Huaier granules in the treatment of stage Ⅱ-Ⅳ primary ovarian cancer, fallopian tube cancer, and peritoneal cancer after satisfactory tumor reduction (R0/R1). Twenty-five patients with FIGOⅡ-Ⅳ ovarian cancer, peritoneal cancer or tubal cancer confirmed by histopathology were enrolled and treated with Huaier granules. During the study period, the patients were followed up once at 3 months, and the medication was continued until progression or intolerability of toxicity.

This randomized phase II trial studies how well metformin hydrochloride and combination chemotherapy works in treating patients with stage III-IV ovarian, fallopian tube, or primary peritoneal cancer. Drugs used in chemotherapy, such as carboplatin, paclitaxel and docetaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Metformin hydrochloride may help carboplatin, paclitaxel and docetaxel work better by making tumor cells more sensitive to the drugs. Studying samples of blood and tissue in the laboratory from patients receiving metformin hydrochloride may help doctors learn more about the effects of metformin hydrochloride on cells. It may also help doctors understand how well patients respond to treatment. Giving metformin hydrochloride together with combination chemotherapy may kill more tumor cells.

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.

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.
