Filter by:Recently, with the development of minimally invasive surgery and the development of instruments, laparoscopic and robotic surgery are increasing, and laparoscopic and robotic surgery are evolving. The association between the new surgical instruments used in each upper gastrointestinal surgery and the results has been traditionally analyzed through the learning curve, and in addition, the study aims to collect and analyze the utilization of the instrument and surgical results prospectively through surgical video analysis.
This is a single-arm, open, exploratory clinical study to evaluate the efficacy of carrelizumab (PD-1) combined with chemotherapy (SOX/XELOX) as neoadjuvant therapy and to observe the changes of tumor immune microenvironment in patients with locally advanced gastric or gastroesophageal junction cancer (T3-4NXM0).
The purpose of this study is to explore the clinical application value of Double-Stapling End-to-End Gastroduodenostomy Billroth-I Anastomosis in Laparoscopy-Assisted Surgery for Locally Advanced Distal Gastric Cancers.
This study is aimed to investigate the changes in pharmacokinetics and efficacy of antiplatelet agents before and after distal gastrectomy in gastric cancer patients taking oral antiplatelet agents for primary or secondary treatment for cardiovascular disease and to evaluate its impact on the occurrence of postoperative bleeding complications and thromboembolic events.
The aim of this study is comparing the short-term quality of life between laparoscopy-assisted distal gastrectomy and totally laparoscopic distal gastrectomy for gastric cancer.
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.
The aim of the present study is to demonstrated the the safety and feasibility of laparoscopic total gastrectomy comparing with open total gastrectomy.
This is a signle-arm, multi-center, open-lable, phase II study. The objective is to evaluate the effectiveness and safety of tislelizumab + oxaliplatin + capecitabine + PLD in the neoadjuvant treatment of resectable gastric adenocarcinoma.
To evaluate the efficacy and safety of chemoradiotherapy combined with tirelizumab in the treatment of initial unresectable locally advanced gastric cancer or gastroesophageal junction cancer.
