Active clinical trials for "Peritoneal Neoplasms"

This is an observational retrospective cohort study to determine metachronous peritoneal carcinomatosis in a specific subgroup of colon cancer patients, those with a final pathologic exam corresponding to pT4 tumors. Based on a sample size calculation of 1152 patients, a retrospective review of a three year period of every participant hospitals, 50 in total, of different characteristics, was stablished. Demographic, clinical, operative, histologic and oncologic follow-up variables were recorded.

Primary objectives: To develop peritoneal carcinomatosis index (PCI) for ovarian cancer, tubal cancer and primary peritoneal cancer that can represent perioperative intraperitoneal tumor burden objectively Secondary objectives: To establish the relationship and find out clinical significance between PCI, tumor location and tumor characteristics

Objectives to investigate the incidence and associated factors for early postoperative cognitive dysfunction in the patients with peritoneal surface malignancies undergoing cytoreductive surgery and hyperthermic intraperitoneal chemo-therapy(CRS-HIPEC).Methods fifty patients aged 18-65 yr were included in the research and were grouped base on the score of neuropsychological assessments which had done in the ward at 7 day before and after the surgery. The investigators monitored various indicators in the perioperative period, such as age, body weight, sex, education, duration of operation, intraoperative blood loss, cardiovascular events, amount of fluid infused per hour. Meanwhile, the concentration of serum amploid A (SAA),IL-1beta,TNF-alpha,HMGB1,S100b,cortisol and Abeta40 were measured at the various stage of the operation and 24 hours after the operation, and the differences of data between postoperative cognitive dysfunction(POCD) and Non-POCD groups were analyzed.

Introduction Modern treatment of peritoneal carcinomatosis (PC) combines an aggressive cytoreductive surgery (CRS) of all macroscopic disease and hyperthermic intraperitoneal chemotherapy (HIPEC) performed at the time of surgery. It is considered a high risk procedure and post-operative intra-abdominal bleeding is a major issue as it can delay recovery and promote intra-abdominal infections. In most severe cases (10 to 20% of patients), a second surgery to control the bleeding will be necessary. Major causes of bleeding are : radical resection, extensive peritonectomy, length of surgery, massive transfusion and use of HIPEC. To reduce the risk of intra-abdominal hemorrhage, many strategies have been tried and one of these is the liberal use of FloSeal, but there is no data in this particular field of interest. Over the last 18 months, the investigators have started to use FloSeal in all their cases with large PC and they have observed a dramatic reduction in the rate of reoperation for bleeding and probably secondarily, in the use of blood products, but this has not been measured. Hypothesis FloSeal can reduce the risk of bleeding after CRS and HIPEC procedure. Primary objective To evaluate if the use of FloSeal can reduce the risk of reoperation after CRS and HIPEC procedure in the treatment of PC. Secondary objectives To evaluate if the use of FloSeal can reduce operative blood loss. To evaluate if the use of FloSeal can reduce the need of blood products after CRS and HIPEC procedure. To evaluate if the use of FloSeal can have an impact on other common surgical complications (which can be indirectly bleeding related). To evaluate if the use of FloSeal can have an impact on length of hospital stay.

The most popular surgical treatment of peritoneal cancer is the type known as hyperthermic intraperitoneal chemoperfusion (HIPEC), a type of cytoreductive surgery for which a significantly high survival rate has been demonstrated by several studies. It is widely known that HIPEC entails severe physiological changes and precautions during anesthesia. However, very few studies have systematically outlined and organized these changes for each system, and most existing studies only report retrospective data or are limited to gynecological surgeries. Therefore, the present researchers planned a prospective observational study to determine the physiological changes that occur in patients during HIPEC cytoreductive surgeries performed in the colon and rectal surgery department of the investigators hospital. The investigators planned to monitor the patients' body temperature, metabolism, cardiovascular and respiratory changes during HIPEC cytoreductive surgery and analyze the anesthetic methods applied to identify the optimal anesthetic management strategy for HIPEC cytoreductive surgeries.

The study would examine by hypericin-supported Fluoreszenzlaparoskopy in terms of tumor size, number and location of the combination of photodynamic diagnosis (PDD) and therapy (PDT) with regard to the detection of peritoneal metastases of locally advanced gastric cancer at 50 adult patients.

Pressurised intraperitoneal aerosol chemotherapy is a new surgical technique, developed for the treatment of initially unresectable peritoneal carcinomatosis. The objective of this study was to compare the results of PIPAC associated with systemic chemotherapy with those of systemic chemotherapy alone in patients with gastric peritoneal carcinomatosis without metastasis other than peritoneal, and WHO performance status <3.

SPECT was performed in 51 patients after cytoreductive surgery in combination with intraperitoneal chemotherapy. The detected volume was compared to the number of subsequent sequential postoperative intraperitoneal chemotherapy courses that could be performed without further surgical intervention. SPECT data was found to predict feasibility of sequential postoperative intraperitoneal chemotherapy.

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).

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.
