Background: Although its incidence and mortality has decreased, gastric cancer (GC) is the fourth most common cancer and the second leading cause of cancer-related death worldwide, particularly in China. The number of new cases and deaths may comprise approximately one-half of the global total. The high mortality of GC is partially attributed to late detection and nonspecific symptoms. The current gold standard for diagnosing GC is endoscopic biopsy. However, because of its discomfort to the patient and high cost, screening for early GC (EGC) is a major difficulty in clinical practice, particularly for asymptomatic individuals. Unfortunately, gastric precursor lesions such as intestinal metaplasia (IM), chronic atrophic gastritis (CAG), and persistent Helicobacter pylori (HP) infection increase the difficulty of screening for EGC. Furthermore, the standard serum biomarkers for GC, such as CEA, CA72-4, and CA19-9 achieve a low positive rate. Thus, it is critically important to develop new approaches for diagnosing EGC with high specificity and sensitivity. Objective: To study circulating exosomal lncRNA-GC1 as a potential biomarker for detection of gastric cancer. Eligibility: Participants from two medical centers in China Design: Investigators will use blood samples from participants in the two medical centers. Investigators will use samples from some who developed gastric cancer. The other samples will be from some who stayed cancer free in that time. Participants already gave written informed consent. Investigators will take exosomes from the samples and look for lncRNA-GC1.
This is a phase I clinical study to evaluate the safety and tolerability of CAR-T in patients with CEA-positive advanced malignant solid tumors, and to obtain the maximum tolerated dose of CAR-T and phase II Recommended dose.
This is a single-arm, multi-center phase II clinical study to Evaluate the Safety and Efficacy of Max-40279-01 in Patients With advanced gastric cancer or gastroesophageal junction cancer.
This study was an observational, non-interventional, multicenter retrospective study to evaluate the feasibility and safety of sintilimab combined with chemotherapy (SOX or PS) in the clinical practice of unresectable locally advanced or stage IV gastric cancer/gastroesophageal junction carcinoma.
This study is an open-label, phase II study with a safety lead-in to assess the response rate of induction olaparib and stereotactic beam radiotherapy (SBRT) followed by combination olaparib/pembrolizumab in patients with metastatic gastric and GEJ cancers after at least one of therapy.
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 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.
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.
