Filter by:Approximately 5% to 10% of gastric cancers have MSI-H/dMMR. According to the results of retrospective analysis of CLASSIC and MAGIC, MSI-H/dMMR was a good prognosis and potential negative predictor of adjuvant chemotherapy for resectable gastric cancer. GC patients with MSI-H/dMMR were relatively insensitive to chemotherapy. The prognosis of these patients receiving routine postoperative adjuvant chemotherapy was worse than that with surgery alone. However, these patients were sensitive to immunotherapy. MSI-H/dMMR is one of the most important biomarkers to predict the efficacy of immunotherapy for GC. In this study, patients with MSI-H locally advanced gastric adenocarcinoma after radical surgery with D2 dissection would be randomly treated with conventional adjuvant chemotherapy, PD-1 monoclonal antibody immunotherapy or follow-up observation. We intend to demonstrate that the prognosis of MSI-H GC patients after D2 radical gastrectomy receiving PD-1 monoclonal antibody immunotherapy would be better than that with standard postoperative adjuvant chemotherapy and follow-up observation.
To observe and determine the safety, tolerability, cellular pharmacokinetics and efficacy of TCRx T cells in patients with advanced or recurrent gastric/gastroesophageal junction cancer after failure of first chemotherapy.
In this study, patients with traditional neoadjuvant gastric cancer were used as controls to explore whether the triple pre-rehabilitation interventions of exercise, nutrition and psychology during the neoadjuvant period before surgery could improve the functional reserve of neoadjuvant gastric cancer patients and accelerate postoperative recovery.
The purpose of this study is to investigate the efficacy and safety of intraperitoneal and intravenous nab-paclitaxel plus Camrelizumab and S-1 conversion therapy for gastric cancer with positive exfoliative cancer cells.
This is a prospective pilot study to evaluate the safety and feasibility of neoadjuvant transcatheter infusion and embolism (TACiE) in patients with locally advanced adenocarcinoma of stomach and gastroesophageal junction. The TACiE protocol includes four cycles. Transcatheter oxaliplatin and concurrent embolism on day 1 and oral S-1 on day 1-14 will be administrated in the first and third cycles. Intra-venous oxaliplatin on day 1 and oral S-1 on day 1-14 (SOX) will be administrated in the second and fourth cycles.
An exploratory study of pembrolizumab combined with anlotinib and chemotherapy in the perioperative treatment of locally advanced gastric cancer
Recently, laparoscopic gastrectomy has been gradually accepted by surgeons worldwide for gastric cancer treatment. Complete dissection of the lymph nodes and the establishment of the surgical margin are the most important considerations for curative gastric cancer surgery. Previous studies have demonstrated that indocyanine green (ICG)-traced laparoscopic gastrectomy significantly improves the completeness of lymph node dissection. However, it remains difficult to identify the tumor location intraoperatively for gastric cancers that are staged ≤T3. Here, the investigatorsinvestigated the feasibility of ICG fluorescence for lymph node mapping and tumor localization during totally laparoscopic distal gastrectomy.Preoperative and perioperative data from consecutive patients with gastric cancer who underwent a laparoscopic proximal gastrectomy were collected and analyzed. The investigators want to know if near-infrared fluorescence imaging with ICG can be successfully used in laparoscopic proximal gastrectomy, and if it contributes to both the completeness of D2 lymph node dissection and confirmation of the gastric transection line. The application of ICG labeled near infrared imaging fluorescence laparoscopic technology is still in the stage of exploration and experience accumulation, and it needs to be comprehensively evaluated through a large number of prospective randomized controlled studies.
This study combines artificial intelligence with tongue images, by collating and collecting tongue images and diagnostic and pathological results of gastroscopic diseases, mining and analysing the correlation between tongue images and OLGA, OLGIM stages, Correa sequences and constructing prediction models, to deeply investigate the relationship between tongue images and precancerous diseases, precancerous lesions and gastric cancer.
This is a prospective, open-labelled study to evaluate the efficacy and safety of sequential transarterial chemoembolization with lipiodol and neoadjuvant chemotherapy in the treatment of Initial unresectable gastric cancer.
To compare the incidence of internal hernia, overall survival and short-term surgical safety of routine closure of the surgically created mesenteric defects versus non-closure for patients with adenocarcinoma of the gastric or esophagogastric junction who underwent radical gastrectomy (D1+/D2 lymph node dissection).
