Filter by:- The surgical device used to perform PIPAC procedure is commercialized by a single manufacturer under a monopoly regimen, and a formal training (economically supported by the manufacturer) is mandatory for surgeons who want to buy the device.Relations with the company and solutions to extend training require specific analysis from an ethical point of view. - Based on the growing number of published papers from a growing number of international centers, the controlled training model is not limiting, and it is a successful model of development of this breakthrough innovation. - But with the major involvement of the industry and the control of training, the different levels of interest could induce ethical questions.
Serum lactate is a risk factor for postoperative complications in patients undergoing cytoreduction surgery in peritoneal carcinomatosis
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.
Inflammation plays an important role in the pathogenesis of peritoneal carcinosis. Patients with elevated levels of different inflammation cytokines show a worse prognosis at the time of diagnosis. In women, ovarian and colon cancer are the main causes of peritoneal carcinosis and a comparison of these two different types of peritoneal invasion have not been conducted yet. We found interesting studying the role of immune response, in particular tumour-associated antigens (TAA) that modulate the metastatic process. We will investigate also mitochondrial defects, such as mutations in mt-DNA, potentially involved in carcinogenesis.
Epithelial ovarian carcinoma (EOC) is one of the main cause of death from cancer in women in the Western world. It is often diagnosed at an advanced stage and the disease remains confined to the peritoneal cavity for much of its natural history. Despite a high rate of response to first-line therapy, about 20% of EOC are naturally resistant to platinum and about 2/3 of patients with initial response will recur within 5 years. Most tumour recurrences will develop resistance to systemic platinum over time. The prognosis of these patients with persistent or recurrence disease remains poor despite salvage therapy including alternative systemic chemotherapy and further cytoreductive surgery (CRS). Since twenty years, centers have pursued comprehensive CRS combined with Hyperthermic Intraperitoneal Chemotherapy (HIPEC) for the management of peritoneal surface malignancies (PSM). This combined approach is the standard of care for the management of some rare peritoneal disease such as pseudomyxoma peritonei or peritoneal mesothelioma. EOC should be an ideal target for this loco-regional treatment, as most of its evolution remains confined to intraperitoneal cavity and because of its sensitivity to chemotherapy. Intraperitoneal chemotherapy has been shown to have significant efficacy in frontline EOC in 3 large randomized studies. Recently, French clinical guidelines have been edited to recommend CRS+HIPEC in patients with ovarian, tubal or primitive carcinomatosis FIGOI IIIC, initially not resectable (Grade B). HIPEC adds some advantages to this intraperitoneal chemotherapy: the hyperthermia effect with its direct cytotoxicity demonstrated in vitro, the synergistic effect with some anticancer agents and, the deliverance immediately following CRS, avoiding the problem of "cancer cell entrapment" by postoperative or posttherapeutic adhesions that limits distribution of chemotherapy agents to all sites. The use of HIPEC for EOC was reported into relatively small case-series from single institutions. Results from a single centre cannot be extrapolated to other centres because of the heterogeneity of patient's selection and HIPEC techniques.
The goal of this project is to investigate the extent and role of mesothelial - mesenchymal transition (MMT) and cancer associated fibroblasts (CAFs) in the pathogenesis of colorectal peritoneal carcinomatosis (PC).
The primary objective of this open-label, Phase I, trial is to evaluate the toxicity profile of intraperitoneal talimogene laherparepvec (TVEC) in patients with peritoneal surface dissemination from gastrointestinal or recurrent, platinum-resistant ovarian tumors. The secondary objectives are to evaluate the pharmacokinetic profile and viral shedding of TVEC by measuring viral load in serum and urine as well as viral load in peritoneal washings.
This multicenter, double-blind, 2-arm, randomized study will evaluate the efficacy and safety of bevacizumab plus paclitaxel and caboplatin compared with placebo plus paclitaxel and caboplatin in Chinese participants with newly diagnosed, previously untreated Stage III or Stage IV epithelial ovarian, fallopian tube, or primary peritoneal cancer. Participants whose disease has not progressed after six cycles of paclitaxel and carboplatin with either bevacizumab or placebo will continue treatment with either bevacizumab or placebo until disease progression, unacceptable toxicity, or a maximum of 22 cycles, whichever occurs first.
Treatment for stage 4 gastric cancer with peritoneal carcinomatosis has been unchanged for decades. The median survival for stage 4 gastric cancer is 9-14 months with systemic chemotherapy. Intraperitoneal chemotherapy in combination with systemic chemotherapy is under many clinical trials mainly in Japan, and are showing promising results. This is Korea's first clinical trial on Intraperitoneal Paclitaxel with Systemic mFOLFOX6 chemotherapy.
Prospective, multi-center, non-randomized study to assess the ability of the Cytuity device to collect cell samples from the fallopian tube that can be evaluated for the presence or absence of malignancy.
