Filter by:Laparoscopic sentinel lymph node dissection and stomach preserving surgery in early gastric cancer is less invasive method which can increase quality of life. Current stomach preserving surgery after sentinel lymph node dissection produce transmural communication and expose the tumor to the peritoneum during operation. An endoscopic full-thickness resection method with a simple suturing technique that does not expose the gastric mucosa to the peritoneum (non-exposure simple suturing, NESS) was recently developed. This is the pilot study to prove the feasibility of NESS-EFTR with sentinel node navigation in early gastric cancer patients.
Colorectal carcinoma is a heterogeneous disease that is caused by the interaction of genetic and environmental factors. colorectal carcinoma encompasses a complex disease with different molecular pathways and biological characteristics arising from a multi-step process that implicates several genetic and epigenetic events . The multi-step genetic model involves the loss of function of tumor suppressor genes, such as adenomatous polyposis coli (APC), Telomeres could be a promising marker due to the fact that their lengths change in the colorectal polyp-carcinoma sequence . Moreover, telomere length (TL) is altered in blood cells in patients with colorectal carcinoma - These findings could suggest that changes in TL may take place before the development of the tumor . The two main forms of inflammatory bowel disease (IBD), ulcerative colitis (UC) and Crohn's disease (CD) are characterized by chronic intestinal inflammation and risk of progression to colon cancer. One proposed cause of the latter characteristic is chromosome instability, since the rearrangement of genetic material can lead to activation of oncogenes, loss of tumor suppressor genes and other changes that lead to uncontrolled cell growth. Chromosome instability is particularly associated with UC and has been observed in colon epithelial cells and peripheral blood mononuclear cell. Since genomic instability in peripheral blood mononuclear cells (PBMCs) has been used as a biomarker for global cancer risk in a number of diseases, the latter observation suggests the possibility of a chromosome instability syndrome in UC that could affect all tissues. One possible cause of chromosome instability is telomere dysfunction .
The goal of this study is to learn about the safety and tolerance of autologous TSA-DC cell and evaluate the efficacy and feasibility of the cell therapy compared to the patients' past standard regimen. 20 gastrointestinal solid tumors subjects failed from at least one systemic therapy will be enrolled into the trial and receive a succession of treatment of TSA-DC vaccine.
This project is a multi-center, prospective, randomized controlled clinical observation the safety and efficacy that stage IV limited peritoneal metastasis of gastric cancer patients accept hyperthermic intraperitoneal chemotherapy plus neoadjuvant chemotherapy with CRS and systemic chemotherapy. With advanced-stage gastric patients of confined to the peritoneal as the research object, with median progression-free survival and overall survival, adverse events as the end points.
A single-arm phase II study to evaluate the efficacy and safety of docetaxel plus S-1 (DS) as second-line treatment in patients with AGC.
The purpose of this study is to find out the effect of Dexmedetomidine for treatment of sleep deprivation, pain relief and postoperative recovery on middle-aged and elderly Patients with Gastric Cancer.
Background: Literature often shows limited and discordant data regarding the prognostic value of age in gastric-cancer patients. Generally, disease-specific survival does not seem to be worse in the elderly when compared with younger patients, and therefore gastrectomy with extended lymphadenectomy for non-early tumors is considered the "standard" surgical therapy for all of operable patients, despite any age- or comorbidity-related limitations. Recent trials reported a survival benefit for extended nodal dissection compared with the more limited method, but some Authors found age (and comorbidities) to be a relevant predictor of postoperative complications, conditioning the safety of the surgical procedure itself. Methods/Design: The LELEGA Trial (Limited versus Extended Lymphadenectomy in high risk Elderly with Gastric Adenocarcinoma) is a randomized, clinical multicenter trial. All patients >75 years and with Charlson Comorbidity Score >5 with resectable M0 gastric cancer are eligible for inclusion and randomization. The primary endpoint is 5-year Disease-Specific Survival (DSS). Secondary endpoints include 5-year Overall Survival (OS) and postoperative complications classified according to Clavien-Dindo. Assuming an alpha (two-sided) of 5%, 232 patients per group are necessary to achieve an 80% power to detect a 13% survival difference (from 56% to 69%) between groups. Discussion: LELEGA trial is a prospective, multicenter randomized study to define optimal extent of lymphadenectomy (extended versus limited) in elderly and high-comorbidity gastric cancer patients.
The aim of this study was to compare the efficacy and safety of mFOLFOX, mFOLFIRI and FOLFPTX as first-line treatment in AGC or EGJA.
This study is a prospective, single-center, randomized controlled trial. The study protocol was approved by the Ethics Committee at the First Hospital of Jilin University.The perioperation nutritional status will be assessed in gastric cancer patients within ERAS protocols.The ERAS patients were randomly divided into perioperational nutrition support group and conventional pathway group . Inter-group differences were evaluated for nutritional index,clinical recovery index, complications etc.
The purpose of this study is to determine whether apatinib plus irinotecan can improve progression free survival compared with single irinotecan in patients with advanced gastric cancer or adenocarcinoma of esophagogastric junction who failed one lines of chemotherapy.
