Filter by:Pressurized intraperitoneal aerosol chemotherapy (PIPAC) is a novel minimally invasive drug delivery system for patients with peritoneal metastases (PM). It has been considered as a safe and feasible palliative treatment alternative proven by previous phase I studies. Currently available evidence on feasibility, efficacy and tolerability in Asian populations is limited. In this open-label, single-arm, monocentric clinical trial, investigators aim to evaluate the therapeutic efficacy and complications of PIPAC with oxaliplatin as an alternative on patients of unresectable colorectal cancer with PM and doxorubicin and cisplatin on patients of unresectable gastric and pancreatic cancers with PM. Alternative regimen can be considered multidisciplinary tumour board meeting. Patients will be recruited according to the inclusion criteria and treated for 3 cycles of PIPAC and concurrent systemic chemotherapy. The goal was to repeat PIPAC every 6-8 weeks for at least three procedures, and the delay of the systemic chemotherapy is 2 weeks before and after each PIPAC procedure. If PM was considered to become resectable during PIPAC, patients were discussed at the multidisciplinary tumour board for curative intent cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). The primary outcome is the clinical benefit rate (CBR), measured by an independent radiologist according to Response Evaluation Criteria In Solid Tumors (RECIST) and Peritoneal Cancer Index (PCI) assessed by laparoscopy and histopathological tumour response evaluated by pathologists blinded to clinical outcomes. Key secondary outcomes include the major and minor treatment-related adverse events according to the Common Terminology Criteria for Adverse Events (CTACE) up to 4 weeks after the treatment, Cytological tumour response of peritoneal lavage or ascites, treatment-related characteristics, hospital stay, progression-free survival, overall survival and readmission rate. The proposed study duration is 3 years from the start date and the estimated sample size is 51 according to centre capacity.
The goal of this randomized clinical trial is to investigate whether pressurized intraperitoneal chemotherapy (PIPAC), delivered immediately after minimally invasive D2 gastrectomy and repeated 6-8 weeks later, improves 12-month peritoneal disease-free survival in patients with high-risk gastric adenocarcinoma when compared to standard treatment.
Heterogeneity concerning survival in synchronous peritoneal metastasis from patients with colorectal cancer exists, thereby further classification is urgently required. This study aimed to validate a PSN-AI model based on DNA ploidy, stroma-tumor fraction, and nucleotyping (PSN) for the prediction of survival of synchronous peritoneal metastasis from colorectal cancer.
This Study is designed to test an investigational product (IP) called LSTA1 (Study drug). LSTA1 is a drug designed to improve the delivery of anti-cancer treatments, such as chemotherapy. Improved delivery of chemotherapy may result in improved anti-cancer effects when given with hyperthermic intraperitoneal chemotherapy (HIPEC) in patients with peritoneal metastases. Participants will be randomized to receive LSTA1 with HIPEC or HIPEC alone (without LSTA1) at the time of surgery.
The prognosis of patients with peritoneal metastasis from gastric cancer is extremely poor. Although chemotherapy combined with immunotherapy has achieved promising efficacy in the first-line treatment of advanced gastric cancer, patients with peritoneal metastasis benefit less from this regimen. Hyperthermic intraperitoneal chemotherapy (HIPEC) represents a novel treatment option, which maintains the high concentration of drugs in the abdominal cavity, and improve the anti-tumor efficacy of chemotherapy drugs through the thermo-thermal effect. The purpose of this study is to investigate the efficacy and safety of HIPEC and systemic chemotherapy combined with sintilimab in the first-line treatment of advanced gastric cancer and gastroesophageal junction adenocarcinoma with peritoneal metastasis.
The pilot study will investigate the use of repeated FDG-PET/CT scans in 16 patients with peritoneal metastasis originating from abdominal cancers treated with Pressurized Intraperitoneal Aerosol Chemotherapy. The study will focus on the potential of repeated FDG-PET/CT scans to evaluate the treatment as well as the feasibility in the patient group.
• Suspected patients known to have a primary malignant tumour, patients with metastasis of unknown primary and had incidental peritoneal lesions and will do PET/CT for assessment of peritoneal deposits
To evaluate the efficacy and safety of Sintilimab in Combination With S-1/oxaliplatin With nab-paclitaxel intraperitoneal infusion as First-line Treatment for advanced gastric/gastroesophageal junction (GC/GEJ) adenocarcinoma with malignant ascites
The rationale of the current study is that the addition of intraperitoneal irinotecan (75 mg) to palliative systemic therapy is feasible and safe, and might result in an increased overall and progression free survival in patients with unresectable colorectal peritoneal metastases. The primary objectives are to explore the overall survival for the addition of intraperitoneal irinotecan (75 mg) to palliative systemic therapy in patients with unresectable colorectal peritoneal metastases. Secondary objectives are to assess the progression-free survival, toxicity profile, patient reported outcomes, costs, tumor response during trial treatment, and the systemic and intraperitoneal pharmacokinetics of irinotecan and SN-38. This is a single-arm, open-label, phase II study and patients will receive intraperitoneal irinotecan (75 mg) in combination with modified FOLFOX4 + bevacizumab.
The goal of this study is planing to adopt intra-abdominal perfusion therapy of rmhTNF during radical colorectal cancer surgery to determine whether intra-abdominal therapy has an impact on postoperative intestinal function recovery, anastomotic leakage, postoperative bleeding, postoperative adhesion intestinal obstruction and other complications. On this basis, the effect of rmhTNF on postoperative peritoneal implantation metastasis and long-term survival was further studied. The main question it aims to answer is: To evaluate the safety and efficacy of rmhTNF in the treatment of peritoneal metastases in colorectal cancer. Participants will receive 1. Radical surgery: Surgical methods can be developed or endoscopic (including robotic surgery). Radical resection of colorectal cancer (corresponding resection of colon and rectum plus regional lymph node dissection, regional lymph node dissection including parenteral, intermediate and mesangial root lymph nodes) follows the principle of mesangectomy and tumorless operation. 2. Abdominal heat perfusion was performed twice: the first time, 5 million IUrmhTNF, dissolved in 30-50ml normal saline, was intraperitoneal heat perfusion into the surgical focus after the operation; the second time, rhatitrexed 2.5mg/m2 was injected into the abdominal cavity through thermoperfusion or drainage tube; 3. Postoperative systemic chemotherapy regimen: postoperative adjuvant chemotherapy should be started 3-4 weeks after surgery, and appropriately extended for patients with poor physique, but no later than 8 weeks after surgery. The chemotherapy regimen was determined by the clinician according to pathological stage, molecular typing, and risk factors, referring to the NCCN and CSCO guidelines.
