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 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.
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.
This is a proof-of-concept study designed to investigate HER3-DXd monotherapy in locally advanced or metastatic solid tumors. The study is enrolling cohorts of participants with melanoma [cutaneous/acral], squamous cell carcinomas of the head and neck (SCCHN), and HER2-negative gastric cancerovarian carcinoma, cervical cancer, endometrial cancer, bladder cancer, esophageal carcinoma, pancreatic carcinoma, and prostate cancer.
Abstract Objective: Ramucirumab is a VEGFR2 antagonist. The aim of this trial is to evaluate the efficacy and safety of ramucirumab combined with nab-paclitaxel, lobaplatin and S-1 in neoadjuvant and conversion therapy for advanced gastric cancer. Methods and analysis: This study is a prospective single-center, randomized controlled and open label clinical study containing two cohorts with 140 patients of advanced gastric cancer (Cohort A n=70; Cohort B n=70). The main efficacy indicator is pathological complete response (pCR) of the cancer after neoadjuvant or conversion therapy. The secondary efficacy indicators are R0 resection rate after neoadjuvant or conversion therapy, the incidence of adverse events (AE), progression-free survival (PFS), overall survival (OS), objective response rate (ORR), total response rate and total response time, disease control rate (DCR) and duration of overall response (DOR). Ethics: Ethics approval has been obtained from the Ethics Committee at the First Affiliated Hospital (Xijing Hospital) of Air force Military Medical University (KY20232220-F-1).
This is a multicenter, prospective, phase II clinical study to evaluate the efficacy and safety of intensive treatment with lenvatinib plus tislelizumab and CapeOX as first-line treatment for advanced gastric cancer or gastroesophageal junction adenocarcinoma with PD-L1 positive and low TMEscore. A total of 92 subjects are randomly divided into study group and control group according to 1:1 ratio. Tislelizumab 200mg, iv, d1+ oxaliplatin 130mg/m2, iv, d1+ capecitabine 1000mg/m2, bid po, D1-14, q3w ± Lenvatinib 8mg, qd po regimen are received, respectively (3 weeks as a cycle, a maximum of 8 cycles of treatment). Then the maintenance treatment phase with tislelizumab ± lenvatinib is entered, and the specific dosage is the same as the treatment period. Effectiveness is assessed every 9 weeks (±7 days) until disease recurrence, metastasis, death, or loss of follow-up. The primary endpoint of this study was PFS, and secondary endpoints were OS, ORR, DoR, and DCR.
This clinical trial is studying solid tumor cancers. A solid tumor is one that starts in part of your body like your lungs or liver instead of your blood. Once they've grown bigger in one spot or spread to other parts of the body, they're harder to treat. This is called advanced or metastatic cancer. Participants in this study must have breast cancer or gastric cancer. Participants must have tumors that have HER2 on them. This allows the cancer to grow more quickly or spread faster. There are few treatment options for patients with advanced or metastatic solid tumors that express HER2. This clinical trial uses an experimental drug called disitamab vedotin (DV). Disitamab vedotin is a type of antibody drug conjugate or ADC. ADCs are designed to stick to cancer cells and kill them. This clinical trial uses a drug called tucatinib, which has been approved to treat cancer in the United States and some other countries. This drug is sold under the brand name TUKYSA®. This study will test how safe and how well DV, with or without tucatinib, is for participants with solid tumors. This study will also test what side effects happen when participants take these drugs. A side effect is anything a drug does to the body besides treating the disease.
