Filter by:Gastric cancer with peritoneal carcinomatosis has a poor prognosis, with little treatment options available. The current treatment strategy consists of palliative systemic chemotherapy. However, previous research suggests that systemic chemotherapy is less effective against peritoneal carcinomatosis than against metastases that spread hematogenously. Several studies suggested that in patients with peritoneal carcinomatosis, intraperitoneal chemotherapy (IP) may be superior compared to intravenous chemotherapy. Intraperitoneal chemotherapy could lead to higher concentrations of chemotherapy in the peritoneal cavity for a longer period of time, resulting in an increased cumulative exposure to the peritoneal metastases. A few Asian studies have shown promising results with intraperitoneal chemotherapy in patients with peritoneal carcinomatosis of gastric origin. However, intraperitoneal chemotherapy combined with systemic chemotherapy has not been investigated in Western patients with peritoneal carcinomatosis of gastric origin yet. The objective of this trial is to establish the maximum tolerated dose (MTD) of intraperitoneal administration of irinotecan, added to systemic capecitabine/oxaliplatin (CAPOX) in patients with peritoneal carcinomatosis of gastric origin.
This is a first-in-human, Phase 1 open-label, multicenter, dose escalation, safety, pharmacodynamic, and PK study of exoASO-STAT6 (CDK-004) in patients with advanced Hepatocellular Carcinoma (HCC) and patients with liver metastases from either primary gastric cancer or colorectal cancer (CRC).
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 an observational case-control study to train and validate a genome-wide methylome enrichment platform to detect multiple cancer types and to differentiate amongst cancer types. The cancers included in this study are brain, breast, bladder, cervical, colorectal, endometrial, esophageal, gastric, head and neck, hepatobiliary, leukemia, lung, lymphoma, multiple myeloma, ovarian, pancreatic, prostate, renal, sarcoma, and thyroid. These cancers were selected based on their prevalence and mortality to maximize impact on clinical care. Additionally, the ability of the whole-genome methylome enrichment platform to detect minimal residual disease after completion of cancer treatment and to detect relapse prior to clinical presentation will be evaluated in four cancer types (breast, colorectal, lung, prostate). These cancers were selected based on the existing clinical landscape and treatment availability.
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).
A study from our group (Osterkamp et al. in preparation) used ICG to evaluate intraoperative changes in gastric perfusion when reducing the circulating blood volume by blood withdrawal in pigs. We saw a significant reduction in gastric perfusion with decreased blood volume, and this reduction of gastric perfusion was detectable with ICG. As data from a previous trial (PRESET phase 2 Protocol nr: H-15014904) has shown that chemotherapy decreases the circulating red blood cell volume in patients with gastroesophageal cancer, we wish to evaluate if standard care neoadjuvant chemotherapy also influences gastric perfusion. Gastric perfusion will be assessed during a screening laparoscopy (before chemotherapy) and then compared with a second assessment during gastric resection (after chemotherapy). The gastric perfusion will be measured using fluorescence-guided surgery with Indocyanine Green. Participants will be offered the opportunity to have their blood volume measured during the trial. This is not required in order to take part in the fluorescence angiography part of the study.
The GISSG+2201 study was launched by Shandong Gastrointestinal Surgery Study Group (GISSG). The intention is to establish a multimodal prehabilitation protocol in frail elderly patients who undergo gastric cancer radical surgery, explore the feasibility and effectiveness of the measures and evaluate the effect of program on short-term clinical outcome, recovery index and the long-term tumor-related outcome.
Neoadjuvant chemotherapy has become the mainstream recommended treatment for advanced gastric cancer. However, due to the heterogeneity of gastric cancer, part of some patients fail to benefit from the treatment. This project aims to compare the clinical efficacy of individualized neoadjuvant therapy based on patient-derived organoid drug sensitivity assay and traditional regimen, exploring the advantages and disadvantages of these two treatments. And access the safety and clinical value of the personalized neoadjuvant therapy based on patient-derived organoid drug sensitivity assay in advanced gastric cancer.
