Filter by:Gastric cancer continues to have a poor prognosis primarily due to the inability to detect it in its early stages. This study will develop and validate a blood assay to facilitate the non-invasive detection of gastric cancer.
This is a pilot study to investigate the usefulness of closure of mucosal defect after gastric endoscopic submucosal dissection (ESD) in patients that are at high risk of post-procedural haemorrhage. Delayed haemorrhage is still an important adverse event of ESD, occurring more frequently for gastric lesions. Risk factors identified for delayed haemorrhage include chronic kidney disease, use of antithrombotic agent, lesion size >20mm, specimen size >30mm. Current established methods to prevent this complications could not completely eliminate the chance of bleeding, especially among high-risk cases. Closure of ESD defect may prevent ongoing exposure of submucosal vessels to gastric acid, and further reduce the risk of delayed haemorrhage. The investigators conduct this study to investigate the effect of closing the defect with endoscopic clips and loop. 30 patients who are undergoing gastric ESD deemed high risk of delayed haemorrhage would be recruited, with closure of defect after resection. The rate of delayed haemorrhage would be compared with historical cohort of patients.
The primary purpose of the study is to determine the maximal tolerated dose (MTD) of Oxaliplatin in this phase I study. The secondary objectives are to determine the response rate, progression free survival, overall survival, and safety profiles. Eligible patients will receive a triplet chemotherapy consisting of nab-paclitaxel (Abraxane®) 150 mg/m2 IVD 30 min followed by Oxaliplatin 60 - 85 mg/m2 IVD 2hr at D1, plus oral S-1 35mg/m2 and Leucovorin 30mg twice daily from D1 to D7, every 14 days as a cycle till disease progression.
