Active clinical trials for "Stomach Neoplasms"

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).

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.

Background: Gastric cancers are cancers of the stomach. Hereditary ones are passed from parent to child. Researchers want to gather data about hereditary gastric cancers. They want to learn about changes these cause in the body and about the genes involved. Objective: -To gather data about hereditary gastric cancer. Eligibility: People at least 2 years old with personal or family history with a hereditary gastric cancer. People at least 2 years old with gene changes that lead to such cancer or a lesion that may be hereditary. Design: Participants will be screened in a separate protocol. Participants will have: Physical exam Medical history Blood tests Scans Photos of skin lesions and other findings Gynecology consultation for women Cheek swab (some participants) For some participants, their relatives will be asked to join the study. Some participants will be asked to allow the study to get stored tissue samples for relatives who have died. Some samples will be sent to outside labs. All personal data will be protected. Samples will be destroyed when the study ends. Participants will get the results of genetic testing. Participants who cannot come to the NIH clinic may just give a cheek swab and have genetic testing done. Some participants will be contacted for more testing.

To comparing the stage-for-stage prognosis of patients with cardia and non-cardia gastric cancer after operation.

This study was a prospective, randomized, controlled phase III clinical study to evaluate the efficacy and safety of docetaxel plus oxaliplatin and capecitabine versus oxaliplatin plus capecitabine in the treatment of gastric or gastroesophageal junction adenocarcinoma with postoperative pathological stage IIIB and IIIC.

This study aims to explore the safety and efficacy of Disitamab vedotin combined with Sintilimab in elderly patients with HER2 overexpression Gastric Cancer. This is a single-arm exploratory clinical study. 20 patients with eHER2 overexpression gastric cancer are scheduled to be enrolled. Treatment regimen is Disitamab vedotin 2.5mg/kg and Sintilimab 200mg every 21 days, until disease progression or intolerable adverse reactions or death.

To evaluate the clinical efficacy (safety, feasibility and long-term efficacy) of total robotic versus robotic assisted distal gastrectomy for patients with gastric cancer (cT1-4a, N0/+, M0).

The gastric cancer diagnosis and treatment specifications clearly point out that tumor markers need to be detected in the process of diagnosis, efficacy evaluation and follow-up. However, there is currently a lack of gastric cancer markers with high sensitivity and specificity, and the detection of markers is limited to a single index analysis, which has many shortcomings such as long analysis time, large reagent consumption, and high detection cost. Therefore, this project will use protein chips to detect new types of gastric cancer patient markers and establish a multi-diagnostic model for early screening of gastric cancer. Finally, monoclonal antibodies will be produced against various high-specific tumor markers and a gastric cancer diagnostic kit will be established.

There is no currently available treatment for peritoneal metastasis of gastric cancer. Hyperthermic intraperitoneal chemotherapy (HIPEC) can not only maintain the high concentration of drugs in the abdominal cavity, but also improve the anti-tumor efficacy of chemotherapy drugs through the thermo-thermal effect. In recent years, immunotherapy has made great progress in the treatment of gastric cancer. We want to explore the hyperthermic intraperitoneal chemotherapy (HIPEC) combined with Camrelizumab (SHR-1210) and intravenous chemotherapy for Creating the Operation Chance in advanced gastric cancer with peritoneal metastasis.

To identify molecular biomarker panel correlating with efficacy of trastuzuamb in advanced HER2 positive gastric cancer patients. To observe the molecular evolution of HER2 positive gastric cancer during treatment by ctDNA detection.
