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 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.
Data demonstrating the efficacy of PIPAC in patients with regionally advanced gastric cancer with positive peritoneal cytology and/or minimal peritoneal disease is limited due to the relatively recent development of this technique and its historical preferential use in palliative patients with disseminated peritoneal metastasis. Existing data suggest PIPAC administered every six weeks in conjunction with standard treatment may work as an adjunct to conventional systemic neoadjuvant chemotherapy. PIPAC protocols have been established both for gastric cancer as well as other intra-abdominal malignancies and have a good safety profile. Given these promising findings, a study protocol is proposed herein to further investigate PIPAC for the treatment of a highly selected group of patients with regionally advanced gastric cancer (positive peritoneal cytology and/or minimal peritoneal disease).
Patients with stage cT3-4N+M0 gastric cancer were recommended to receive neoadjuvant chemotherapy before radical surgery in terms of the eradication of micrometastasis in addition to local control, higher compliance with intensive chemotherapy, and avoidance of futile surgery by detection of initially invisible distant metastasis after rapid disease progression. However, in some studies, gastrectomy followed by neoadjuvant chemotherapy failed to demonstrate survival benefits for these patients. And peritoneal recurrence was the most common and devastating reason. Hyperthermic intraperitoneal chemotherapy (HIPEC) was introduced for peritoneal cancer last century. A few studies suggested HIPEC could improve prognosis in patients with limited peritoneal metastasis from various cancer. In summary, we conducted this study to confirm the efficacy and safety of HIPEC after gastrectomy in patients with advanced gastric cancer received neoadjuvant chemotherapy.
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.
In this phase 2 study, we combined sintilimab, paclitaxel and S-1 as regimen to treat gastric cancer patients with peritoneal metastasis. We are aim to estimate the efficacy and safety of this regimen in the phase 2 study.
This was a retrospective case-control study designed and conducted under the approval of the ethic committee of Tehran University of Medical Sciences. All patients with gastric cancer referring to Cancer Institute, Tehran University of Medical Sciences, Tehran, Iran, during February 25th and December 25th 2020, were enrolled to the study.
HIPEC-AS01 is an open, prospective, single-center phase II clinical study, which will include "cT4aNxM0, P0 or cTxNxM1, P1" patients with gastric or esophagogastric junction adenocarcinoma, to evaluate the efficacy and safety of systemic chemotherapy with HIPEC combined with AS in the perioperative period. Patients enrolled will be divided into three groups. Among them, group A is the patients with locally resectable GC; group B is patients with peritoneal metastasis stage P1a or P1b, group C is patients with peritoneal metastasis stage P1c. The primary purpose is to evaluate the 3-year overall survival rate.
Feasibility study regarding 20 Patients with peritoneal metastases from colorectal cancer treated with cytoreductive surgery and HIPEC and subsequently with 4 courses of normothermic intraperitoneal chemotherapy - long term (NIPEC-OXA) with oxaliplatin.
Pressurized intraperitoneal aerosol chemotherapy (PIPAC) is a novel drug delivery system that allows the direct application of chemotherapeutic agents into the peritoneal cavity. It boosts improved distribution, enhanced tissue uptake and repeatability using minimally invasive access. It was devised to palliate the local symptoms of extensive peritoneal metastases (PM) in patients who are not amenable to curative surgery. This study is to determine safety and feasibility of PIPAC in patients with PM from Gastrointestinal (GI) cancer, Hepato-Pancreato-Biliary (HPB) cancer, and other rare malignancies.
IPXELOX will investigate the safety, tolerability, and antitumor activity of intraperitoneal paclitaxel in combination with chemotherapy in patients with advanced gastric cancer with peritoneal metastasis. Study hypotheses: Intraperitoneal paclitaxel administered to subjects at the recommended phase 2 dose will show manageable safety and tolerability and anti-tumor efficacy with systemic capecitabine and oxaliplatin in advanced gastric cancer with peritoneal metastasis.
