Filter by:Diffusion-weighted magnetic resonance imaging (DWI/MRI) has been described in recent literature as a highly sensitive and specific modality for the detection of peritoneal metastases PM. It has been demonstrated to be superior to CT for patients with known peritoneal disease from colorectal and gynaecological malignancies as a staging tool for cytoreductive surgery. It was also demonstrated to be superior for the detection of PM for gastric cancer patients otherwise considered with a resectable tumor. However, the literature is scarce on the role of DWI/MRI in the detection of peritoneal recurrence for patients with high-risk features, either colorectal cancer (CRC) or appendiceal neoplasms (AN). The aim of this study is to prospectively assess the added value of whole-body DWI/MRI (WB-DWI/MRI) to CT and diagnostic laparoscopy for detection of PM in the follow-up of patients presenting with CRC or AN and high-risk features for peritoneal recurrence and evaluate how it correlates with intraoperative findings.
In this study, the investigators tend to highlight pre and peroperative factors that predict major postoperative complication after a surgery for resection of peritoneal carcinomatosis. Factors associated with major postoperative complications were used to elaborate un predictive nomogram model. A score was assigned for each factor of the nomogram which correspond to the weight of the association of the factor with the occurrence of the major postoperative complication. The nomogram assessed the probability of major postoperative complication after surgery by adding up the scores identified on the "Points" scale for each factor. The total score projected from the "Total points" axis to the "Risk of major postoperative complication" axis, indicated the probability of major postoperative complication occurrence. A cut-off of total score was calculated to identify patients at low or high risk for major postoperative complications. The developed nomogram may be a helpful tool to adapt postoperative monitoring of patients after surgery of peritoneal carcinomatosis resection according to the risk of occurrence of a major postoperative complication.
Peritoneal carcinomatosis (PC) in gastric cancer (GC) is considered a fatal disease, without expectation of definitive cure. Since conventional surgery is not indicated in the palliative setting, and systemic chemotherapy treatments are not sufficient to contain the disease, a multimodal approach associating intraperitoneal (IP) chemotherapy (CMT) with surgery may represent an alternative for these patients. IP CMT has shown superior results to conventional treatment in patients at this stage of the disease, and can achieve complete regression of lesions in a significant portion of cases. Once response to treatment is achieved, patients become fit for curative surgery, which offers a new perspective on the survival in these previously unresectable cases, and raising survival rates to similar levels to patients undergoing surgery with curative intention. Thus, the aim of this study is to evaluate the complete response rate and curative resection in patients with PC by GC at Instituto do Cancer do Estado de São Paulo (ICESP) treated with IP CMT. Patients prospectively included in the study will undergo implantation of a peritoneum catheter to perform outpatient IP CMT in order to promote the regression of lesions. Those with complete regression may be referred for surgical treatment, curing a portion of these patients. The diagnosis of PC will be performed by conventional cytological, immunohistochemical and liquid cytology methods to determine the presence of tumor cells in the peritoneal lavage and to evaluate the sensitivity of the methods. In addition, it is proposed in the study the storage of material for further study of circulating markers in peripheral blood and peritoneal lavage that may be related to response or resistance to treatment. It is believed that IP CMT may not only increase the survival of patients with PC, but also offer the possibility of cure for a significant portion of patients who are currently without treatment prospects and with a median survival of only six months.
Peritoneal carcinomatosis (PC) is a miserable disease with poor treatment outcome. Intraperitoneal administration of anticancer drugs enables an extremely high concentration of drugs to directly contact the target cancer lesions in the peritoneal cavity. However, its effectiveness is limited by the intraperitoneal distribution and penetration of the drug. Pressurized intraperitoneal aerosol chemotherapy (PIPAC) is an innovative intraperitoneal chemotherapy concept that enhances efficacy by taking advantage of the physical properties of gas and pressure. Electrostatic precipitation pressurized intraperitoneal aerosol chemotherapy (ePIPAC) may further enhance these benefits. This research study serves to determine the safety profile and tolerability of PIPAC/ePIPAC with paclitaxel. It will determine the maximal tolerated dose (MTD) and evaluate the safety and tolerability, and pharmacokinetics of PIPAC/ePIPAC paclitaxel in pre-treated patients with peritoneal carcinomatosis (PC). It may offer a novel and effective option of treatment for patients with PC, who, at present have limited options involving the use of systemic chemotherapy and who suffer from poor life expectancy and poor quality of life.
Combined chemotherapy consisting of endovenous Nabpaclitaxel-Gemcitabine and Nabpaclitaxel-PIPAC may be a promising treatment for patients affected by pancreatic cancer PM who are in need of curative options. The purpose of this study is to evaluate the antitumoral activity of combined Nabpaclitaxel-PIPAC and systemic Nabpaclitaxel-Gemcitabine chemotherapy for pancreatic cancer peritoneal metastases. Secondary objectives include the evaluation of the feasibility, the safety, further assessment of the antitumoral activity, the overall and progression free survival, the QoL, the pharmacokinetics of Nabpaclitaxel PIPAC. Furthermore, the study aims to evaluate the patients' nutritional status and the molecular evolution of PM along treatment with a time-course translational research.
Diffusion-weighted magnetic resonance imaging (DWI/MRI) has been described in recent literature as a highly sensitive and specific modality for the detection of peritoneal metastases (PM). It has been demonstrated to be superior to computed tomography (CT) for patients with known peritoneal disease from colorectal and gynaecological malignancies. However, the literature is scarce on the role of DWI/MRI in patients with pancreatic ductal-adenocarcinoma (PDAC). The aim of this study is to prospectively assess the added value of whole-body DWI/MRI (WB-DWI/MRI) to CT for detection of PM in the preoperative staging of patients with high-risk PDAC and evaluate how it correlates with intraoperative findings.
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.
The PIPAC NAL-IRI study is designed to examine the maximal tolerated dose of nanoliposomal irinotecan (Nal-IRI, Onivyde) administered with repeated pressurized intraperitoneal aerosol chemotherapy (PIPAC), in a monocentric, phase I trial.
The aim of this study is to assess whether there are differences in PERITONEAL RECURRENCE in patients with Colon Cancer Peritoneal Metastases treated with complete surgical resection and systemic chemotherapy, with (Group 1) or without (Group 2) HIPEC with Mitomycin-C.
Background: Tumors that have spread to the lining of the abdomen from other cancers, such as cancer of the appendix, colon, or ovary, are called peritoneal carcinomatosis. In most cases, outcomes are poor. Researchers want to test a new treatment. Objective: To learn if the combination of oral nilotinib plus paclitaxel given by IV and directly into the abdomen can reduce tumors enough for people to have surgery. Eligibility: Adults aged 18 and older with peritoneal carcinomatosis that is too widespread for surgery. Design: Participants will be screened with: Physical exam Medical history Blood and urine tests Electrocardiogram Laparoscopy. They will get general anesthesia. Small cuts will be made in their abdomen. Tissue and fluid samples will be taken. Surveys about their health CT scans of their torso Participants will have up to 4 more laparoscopies. During the first procedure, a port will be placed under the skin of their abdomen (an IP port). It will be attached to a catheter that is placed in their abdomen. Participants will get treatment in 3-week cycles, for 3 or 6 cycles. They will take nilotinib by mouth twice daily. They will get paclitaxel by IP port (once per cycle) and by IV (twice per cycle). After cycles 3 and 6, they will have a laparoscopy and CT scans. Then they may take nilotinib and get IV paclitaxel for up to 1 year. At study visits, participants will repeat some screening tests. About 6 weeks after treatment ends and then every 3 months for 3 years, participants will have follow-up visits at NIH or with their local doctor.
