Filter by:The results of PET/MRI and PET/CT in each recruited gastric cancer patients will be compared.
Splenic hilum remains challenging during total gastrectomy with D2 lymphadenectomy.The application of minimally invasive surgery for advanced gastric cancer is gaining popularity. The investigators aim to compare the safety and feasibility of LTG and OTG for advanced proximal gastric cancer.
The purpose of this study is to determine whether intraperitoneal immunotherapy (with interleykin-2 - human cytokine reaction activator) with systemic chemotherapy will be more effective than systemic chemotherapy alone in patients with gastric cancer and verified free cancer cells in abdominal cavity in improving the long term outcomes and overall survival of further surgical treatment.
Without high diagnostic efficacy of endoscopic forceps biopsy (EFB) and with low diagnostic efficacy of narrow band imaging (NBI) in novice endoscopists and endoscopists of community hospitals in China, it is urgent to improve diagnostic efficacy for gastric cancerous lesions.The investigators will conduct a study to develop and validate a diagnostic model based on NBI for early gastric cancerous lesions under endoscopic observation.
The purpose of this study is to make nationwide registry for antimicrobial resistance of Helicobacter pylori using single method with agar dilution in Korea.
The investigators intend to conduct a randomized controlled study to find if combining HIPEC (hyperthermic intraperitoneal perfusion chemotherapy) with post-neoadjuvant chemotherapy D2 resection could improve survival for patients with advanced gastric cancer, while comparing with the traditional approach of D2 resection after neoadjuvant chemotherapy.
The purpose of this study is to evaluate the effect of a multimodal pre-operative prehabilitation programme during neo-adjuvant therapy on cardiopulmonary exercise performance and insulin resistance prior to resection for oesophago-gastric cancer.
Scirrhous gastric cancer, also known as linitis plastic or Borrmann type 4, is an aggressive tumor with an extremely poor prognosis. Aggressive surgical procedures and adjuvant chemotherapies have not improved the survival rate. The purpose of this study is to determine whether neoadjuvant Chemotherapy with SEEOX regimen via intra-arterial and intravenous administration are effective in the treatment of Borrmann type 4 gastric cancer.
Spleen Deficiency Syndrome(SDS)is a widely researched issue, but due to the limitations of the research methods, the scientific mechanism of SDS is biased and not comprehensive. SDS would be researched in this project deeply and systematically with modern life-scientific methods. Based on the previous work, the participants, with SDS, suffering from Qi deficiency syndrome--chronic superficial gastritis--chronic atrophic gastritis--gastric cancer would be included, and the corresponding research would be conducted at the molecular-cell-gastric tissue level, and at the same time, systematical biological database of SDS would be built by systematical biological methods, such as pioneered SPARS sequencing technology created in our research group, proteomics and metabonomics. Under the above work, the investigators would conduct data mining and molecular network analysis, and then verify the key functions. By analyzing the systematical biological features of syndrome and its relationships with constitution and disease, this study would provide a new basis for objective reality of syndrome, and also offer a crucial premise of revealing biological basis for syndrome correctly, which is of important theoretical and practical significance.
Background: Gastric cancer (GC) is major global health concern and the second leading cause of cancer deaths worldwide. Amplification of Her2/neu gene and/or overexpression of the Her2/neu protein have been observed in GC. Trastuzumab (Herceptin™) is an anti-Her2/neu antibody, which has been successfully applied in GC. However, the intratumoral heterogeneity of Her2/neu overexpression and amplification in GC should be noticed. The investigators investigated the significance of evaluating Her2/neu expression in different paraffin blocks of tumor tissue in GC. Methods: 2000 GC patients from ten centers, patients were divided into a cohort using one tumor tissue paraffin block (cohort 1, n=1000) and a cohort using dual tumor tissue paraffin blocks (cohort 2, n=1000) when evaluating Her2/neu expression status by immunohistochemistry (IHC). In cohort 2, the investigators combined the results from two different paraffin blocks and used the higher one as the final score.
