Filter by:The purpose of this study to find out whether adding trastuzumab and pembrolizumab to standard chemotherapy is an effective treatment for resectable HER2+ esophagogastric cancer.
The goal of this clinical trial is to evaluate the efficacy and safety of radiotherapy combined with chemotherapy and anti-PD-1 immunotherapy followed by surgery for the primary and metastatic lesions in patients with limited metastatic gastric or gastroesophageal junction adenocarcinoma. The main questions it aims to answer are: 1) If the multimodal treatment which includes anti-PD-1 immunotherapy and local therapies will improve the survival of this group of patients. 2) If the multimodal treatment which includes anti-PD-1 immunotherapy and local therapies can be performed safely in this group of patients. Participants will receive short course hypofractionated radiotherapy (HFRT) for the primary lesion, HFRT or stereotactic body radiotherapy (SBRT) for metastatic lesions, combined with systemic chemotherapy and anti-PD-1 immunotherapy. For patients with HER2-positive cancer (defined as IHC 3+ or 2+/ISH+), trastuzumab is used along with chemotherapy and anti-PD-1 antibody. Then, surgical resections of primary and metastatic lesions are performed as much as possible. For patients who need a widely invasive surgical approach or are inoperable, local ablative therapies such as radiofrequency ablation (RFA) and microwave ablation (MVA) can be alternatives. For patients undergoing surgical resections, postoperative treatment includes chemotherapy, which is determined by the researcher, and PD-1 antibody, which will be maintained until one year after surgery.
HS-20093 is a humanized IgG1 antibody-drug conjugate (ADC) which specifically binds to B7-H3, a target wildly expressed on solid tumor cells. The objectives of this study are to investigate the anti-tumor activity, safety, pharmacokinetics and immunogenicity of HS-20093 in Chinese advanced esophageal carcinoma and other solid tumor patients.
The objective is to investigate the safety and effectiveness of rhomboid intercostal and subserratum plane (RISS) block for postoperative analgesia after minimally invasive McKeown esophagectomy (MIE-McKeown).
Gastric cancer is the third leading cause of morbidity and mortality among malignant tumors in China, and less than 30% of patients can be cured by surgery. Liver metastasis, retroperitoneal lymph node metastasis and peritoneal metastasis are the most common metastatic sites of gastric cancer, which are also the important causes of death. Improve the conversion of oligonucleotides transfer patients resection rate, prolonged progression-free survival of these patients, is an important direction to improve survival of patients with advanced gastric cancer; This study was a prospective, single-arm, multi-center clinical study. We plan to treat patients with gastric cancer/gastroesophageal junction adenocarcinoma with liver and/or retroperitoneal lymph node metastasis only with XELOX regimen + fruquinitinib + sintilimab for 4-6 cycles before surgery/ablation conversion therapy to achieve tumor-free status as far as possible. To explore the value of conversion therapy in patients with intrahepatic oligometastasis of gastric cancer.
The treatment efficacy for stage IVb esophageal cancer has been improved through chemotherapy combined with immunotherapy recently. On this basis, the investigators intend to conduct a prospective, multicenter phase III clinical trial to assess whether radiotherapy with concurrent chemotherapy and immunotherapy could further improve the survival of patients with metastatic esophageal cancer. Accompanied tissue samples, blood samples and urine samples will be analyzed by molecular biological detection (Including Whole Exome Sequencing and proteomics) to explore potential biomarkers for predicting outcomes, efficacy and toxicity.
The treatment efficacy for stage IVb esophageal cancer has been improved through chemotherapy combined with immunotherapy recently. On this basis, the investigators intend to conduct a prospective, multicenter phase II clinical trial to assess whether radiotherapy could further improve the survival of patients with metastatic esophageal cancer responding to PD-1 Inhibitor plus chemotherapy. Accompanied tissue samples, blood samples and urine samples will be analyzed by molecular biological detection (Including Whole Exome Sequencing and proteomics) to explore potential biomarkers for predicting outcomes, efficacy and toxicity.
This phase II trial tests how well preoperative (prior to surgery) radiation therapy with fluorouracil, oxaliplatin, and leucovorin calcium (FOLFOX) works for the treatment of stage I-III esophageal or gastroesophageal junction adenocarcinoma. Hypofractionated radiation therapy delivers higher doses of radiation therapy over a shorter period of time and may kill more tumor cells and have fewer side effects. Fluorouracil stops cells from making deoxyribonucleic acid (DNA) and it may kill tumor cells. Leucovorin is not a chemotherapy medication but is given in conjunction with chemotherapy. Leucovorin is used with the chemotherapy medication fluorouracil to enhance the effects of the fluorouracil, in other words, to make the drug work better. Oxaliplatin is in a class of medications called platinum-containing antineoplastic agents. It damages the cell's DNA and may kill tumor cells. Giving preoperative hypofractionated radiation with fluorouracil and oxaliplatin may kill more tumor cells in patients with stage I-III esophageal or gastroesophageal junction adenocarcinoma.
This is a randomized, single-center clinical trial that will compare the efficacy of two substances used in the submucosal cushion formation stage of endoscopic submucosal resections of early esophageal malignant neoplasms. Such substances are hyaluronic acid in the form of TS-905 Blue Eyeₒ and hydroxyethylamide (Voluven®).
Esophageal cancer is the seventh most common type of cancer in the world, with an estimated global incidence of 604,100 new cases per year. The main symptom of esophageal cancer is dysphagia, associated or not with weight loss. Unfortunately, due to asymptomatic presentation in the early stages, more than half of patients are diagnosed in advanced stages of the disease, becoming ineligible for treatment with curative intent. In this sense, chemotherapy and radiotherapy are the pillars of palliative treatment, often regressing the injury and improving symptoms. However, some patients persist with dysphagia. In this scenario, esophageal prostheses are one of the main tools in the palliative treatment of esophageal cancer dysphagia, obtaining rapid and lasting relief of dysphagia. This study aims to compare fully covered (FC-SEMS) and partially covered (PC-SEMS) esophageal prostheses in this context, evaluating the number of reinterventions in each group, as well as the occurrence of adverse events. However, it is expected that with the data obtained it is possible to develop clearer and more effective protocols in the palliation of malignant dysphagia of esophageal stenosis.
