Active clinical trials for "Stomach Neoplasms"

The aim of this study is to define the role of H. pylori eradication in the prevention of gastric cancer and its precursors in the context of a population-based endoscopic screening program.

The purpose of this study is to evaluate the efficacy and tolerability of the maintenance treatment of Apatinib/Capecitabine after fluorouracil and platinum based first-line chemotherapy in advanced gastric cancer.

The PIONEER Initiative stands for Precision Insights On N-of-1 Ex vivo Effectiveness Research. The PIONEER Initiative is designed to provide access to functional precision medicine to any cancer patient with any tumor at any medical facility. Tumor tissue is saved at time of biopsy or surgery in multiple formats, including fresh and cryopreserved as a living biospecimen. SpeciCare assists with access to clinical records in order to provide information back to the patient and the patient's clinical care team. The biospecimen tumor tissue is stored in a bio-storage facility and can be shipped anywhere the patient and the clinical team require for further testing. Additionally, the cryopreservation of the biospecimen allows for decisions about testing to be made at a later date. It also facilitates participation in clinical trials. The ability to return research information from this repository back to the patient is the primary end point of the study. The secondary end point is the subjective assessment by the patient and his or her physician as to the potential benefit that this additional information provides over standard of care. Overall the goal of PIONEER is to enable best in class functional precision testing of a patient's tumor tissue to help guide optimal therapy (to date this type of analysis includes organoid drug screening approaches in addition to traditional genomic profiling).

Based on multiple studies, the immune (systemic inflammation) and nutrition index were correlated with short- and long-term prognosis for gastric cancer. With the increasing application of preoperative treatments (chemotherapy and chemoradiotherapy), the issues concerning how are the immuno-nutrition index be altered under the effects of perioperative treatments and what are the clinical values of these index should be clarified.

DRAGON III research, Neoadjuvant Chemotherapy (FLOT versus SOX) for Gastric Cancer, is an investigator initiated; phase 3, open label, multi-center randomized controlled study.

This phase II trial investigates how well oral cryotherapy plus acupressure and acupuncture compared with oral cryotherapy alone work in decreasing chemotherapy-induced peripheral neuropathy in patients with gastrointestinal cancer who are receiving oxaliplatin-based chemotherapy. Acupressure is the application of pressure or localized massage to specific sites on the body to control symptoms such as pain or nausea. Acupuncture is the technique of inserting thin needles through the skin at specific points on the body to control pain and other symptoms. Cryotherapy uses cold temperature such as oral ice chips to prevent abnormally increased pain sensation. Giving oral cryotherapy with acupressure and acupuncture may work better in decreasing chemotherapy-induced peripheral neuropathy from oxaliplatin-based chemotherapy in patients with gastrointestinal cancer compared to oral cryotherapy alone.

The main purpose of this study is to compare the feasibility and efficacy of neoadjuvant chemotherapy (modified SOX) for elderly patients with locally advanced gastric cancer.

Gastric cancer is among the most common malignant tumors nationwide with high morbidity and mortality. Attributing to its insidious onset and rapid progress, 70% of patients with gastric cancer were initially diagnosed at an advanced stage. In advanced gastric cancer, systemic treatment based on chemotherapy drugs, targeted drugs, and immune checkpoint inhibitors remains the main regimens. Among current standard treatment regimens, though HER2-positive and MSI-H/dMMR statuses indicate the treatment efficacy of trastuzumab and immune checkpoint inhibitors, there is still lack of robust biomarkers for predicting treatment efficacy. Tumor microenvironment as pivotal components of solid tumor, significantly influences therapeutic response and clinical outcome. The study is a multi-center, observational study to evaluate the relationship between standard treatment efficacy and the tumor microenvironment in advanced gastric cancer. In addition, the study comprehensively evaluated the landscape of the tumor microenvironment characteristics of gastric cancer, and aimed at establishing robust biomarkers for predicting prognosis and treatment efficacy to finetune treatment strategies.

The purpose of this study is to enhance the care of older metastatic gastric cancer (mGC) patients by increasing awareness among oncology providers of the unique aspects of care required for older patients. The goal of the study is to educate providers on the utility of geriatric assessment in guiding therapy of older mGC patients. The investigators will also assess the feasibility and benefit of incorporating geriatric self-assessments into clinical practice. The study will include four phases.

The study was designed as single-country, multi-center, open-labelled, randomized (1:1), phase II trial. 238 patients with medically and technically operable advanced gastric adenocarcinoma in middle or distal 1/3 of stomach are enrolled and randomly assigned to laparoscopic gastrectomy group and open gastrectomy group. 4 cycles of mFLOT chemotherapy will be conducted before and after gastrectomy. The primary objective of this study is comparison of D2 lymph node dissection compliance rate between open surgery group and laparoscopic surgery group after neoadjuvant chemotherapy.
