Filter by:The goal of this study is to analyze the tumor microenvironment (TME) in gastric cancer patients treated with combined immunotherapy and chemotherapy. The main questions it aims to answer are: - Provide profiles of TME between pre-treatment and post-treatment to gain insights into the mechanisms of immunotherapy combined with chemotherapy in advanced gastric cancer - Investigate the crucial factors affecting treatment efficacy by comparing gastric cancer patients with varying treatment responses
This is a single-arm, open-label, multi-center clinical study to evaluate the efficacy and safety of PD-1/CTLA-4 bispecific cadonilimab in combination with oxaliplatin/capecitabine (CapeOX) in the first-line treatment of advanced gastric cancer or gastro-esophageal junction adenocarcinoma with a high tumor microenvironment score (TMEscore). The study plans to enroll 50 patients to receive cadonilimab 100mg/kg, iv, q3w + CapeOX (oxaliplatin 130mg/m2, vd, d1 + capecitabine 1000mg/m2, po, bid, D1-14, q3w, with 3 weeks as a cycle and a maximum of 8 cycles of treatment. Then the maintenance treatment phase with cadonilimab ± capecitabine is entered, and the specific dosage is the same as the treatment period. Effectiveness is assessed every 9 weeks (±7 days) using RECISIT 1.1 until disease recurrence, metastasis, death, or loss of follow-up. The primary endpoint of this study was PFS, and secondary endpoints were OS, ORR, and safety.
Evidence of implementation of laparoscopic total gastrectomy (LTG) for locally advanced gastric cancer (GC) remains inadequate. This study aimed to compare short- and mid-term outcomes of LTG versus open total gastrectomy (OTG) for cT2-4a GC.
This clinical study was a prospective, single-center, single-arm exploratory study. Subjects who meet the inclusion criteria will be enrolled in this study, where surgeons will perform single-port robot-assisted gastrectomy, and explore and evaluate the safety and efficacy of this clinical application.
This study is a single-center, single-arm, open-label, phase II clinical trial designed to evaluate the efficacy and safety of Paclitaxel Polymeric Micelles for Injection for the treatment of patients with advanced pancreatic adenocarcinoma, cholangiocarcinoma, lung cancer, gastric cancer, esophageal carcinoma, or breast cancer that are resistant to Taxanes. Subjects are given paclitaxel polymeric micelles for injection, three weeks constitutes one cycle of treatment. If subject does not develop disease progression , the subject continues treatment until disease progression (RECIST 1.1) or develops an intolerable toxicity, initiation of a new anti-cancer drug, withdrawal from the study, death, or loss of follow-up. This is a single-arm, small-sample clinical study with the primary efficacy goal of objective remission rate (ORR). The parameters of the trial were set: assuming a class I error of 0.025 unilaterally, power=90%, and a 15% improvement in ORR for objective remission rate, a total of 20 subjects would be required, and a total of 25 would be required for enrolment, taking into account a 20% shedding.
This study is a single center, phase II study, to evaluate the effectiveness and safety of PD-1 Antibody(Tislelizumab) Plus Irinotecan Combined With POF(paclitaxel plus oxaliplatin plus 5-fluorouracil plus leucovorin) , in the first-line treatment for patients with advanced/metastatic gastric cancer.
Gastric cancer is an important disease burden that threatens human health. Due to the complex biological characteristics of gastric cancer, the research on gastric cancer is still at a low level. Organoid technology is a breakthrough technology in cancer research. Gastric cancer organoid is a good model for gastric cancer research by three-dimensional culture of tumor cells in vitro, which simulates the spatial morphology and structure of tumors in vivo while preserving the biological characteristics of tumor cells. At present, gastric cancer organoid models have shown great advantages in many fields, such as the mechanism of gastric cancer development, tumor drug resistance, large-throughput chemotherapy drug screening, novel therapeutic target searching, and preclinical validation of novel drugs. In the current clinical trial, investigators cultured organoids from gastroscopic biopsy tissue of gastric cancer patients, and compared the organoids with the sampled tumors, including immunohistochemical indicators (Ki67+/CK20+/CDX2+), WES sequencing results. At the same time according to the guidelines. The recommended treatment plan is to compare the organoid model drug screening results with the clinical drug sensitivity.
The goal of this retrospective study is to compare the efficacy and safety of 3-4 months to 5-6 months of CapOx/SOX adjuvant chemotherapy in pathological N3 gastric cancer patients.
This project proposes to establish a prospective, multicenter, randomized, controlled clinical study to compare the safety and efficacy of Intralesional Rituximab Injection versus Involved Site Radiation Therapy for the treatment of primary ocular adnexal MALT lymphoma. The aim is to provide high-level clinical evidence for the treatment of ocular adnexal MALT lymphoma and to offer patients treatment options that have fewer complications and comparable therapeutic effects.
Perioperative neurocognitive disorders is a common postoperative complication in elderly surgical patients. The role of gut microbiota in cognitive function has been concerned in recent years. Studies suggests that gastrointestinal surgery may affect the gut microbiota, and the effect varies between surgical procedures. In this study, the investigators will compare the differences of gut microbiota between total gastrectomy and double-tract reconstruction, to investigate the effect of gastric acid on the gut microbiota colonizing, and the effect of different surgical procedures on the postoperative cognitive function of proximal gastric cancer patients.
