Filter by:This is a retrospective and prospective multicenter registry to collect long-term data (1 year) on patients who have or will undergo Endoscopic resection such as EMR, ESD, EFTR, STER, etc. within the gastrointestinal tract for endoscopic treatment of early gastrointestinal neoplasms involving the resection of the superficial layers, mucosa and submucosa, of the tract wall. Subjects will be consented for medical chart review. The purpose of this retrospective and prospective registry is to assess long term data on efficacy, safety and clinical outcome of Endoscopic Resection within the gastrointestinal tract (1 year). The registry will evaluate efficacy, technical feasibility, clinical outcome, safety profile and overall clinical management through medical chart review. The procedures the investigators are evaluating are all clinically indicated and will not be prescribed to someone to participate in this registry study.
Phase II trial of AZD2014 in RICTOR amplified or overexpressed GC patients as second-line chemotherapy AZD2014 50mg BD continuous schedule of a 28 day cycle
In line with improvements in oncologic outcome for patients with esophageal cancer, the attritional impact of curative treatment with respect to functional status and health-related quality of life (HR-QL) in survivorship is increasingly an important focus. Functional recovery after surgery for esophageal cancer is commonly confounded by anorexia and early satiety, which may reduce oral nutrient intake with consequent malnutrition and weight loss. One in three disease-free patients has more than fifteen percent body weight loss at three years after esophagectomy. The ESPEN Special Interest Group on cachexia-anorexia in chronic wasting diseases has defined sarcopenia as skeletal muscle index (SMI) of ≤39 cm2/m2 for women and ≤55cm2/m2 for men, while similar cut-off points have been validated in upper gastrointestinal and respiratory malignancies (less than 38.5 cm2/m2 for women and 52.4 cm2/m2 for men). The European Working Group on Sarcopenia in Older People (EWGSOP) additionally recommends that assessment should also include determination of muscle function, for example gait speed or grip strength, where possible. The presence of sarcopenia is associated with increase treatment-associated morbidity, impaired HR-QL, reduced physical and role functioning, and increased pain scores in older adults. In addition, a previous longitudinal study demonstrated that the decline in HR-QL over a six year period in older adults was accelerated in the presence of sarcopenia. As such, sarcopenia may represent a modifiable barrier to recovery and subsequent retention of HR-QL and functional status, and may reinforce a persistent illness identity, among patients following potentially curative treatment for esophageal cancer.
This phase II trial studies the side effects and response of pulsed low dose rate radiation therapy in treating gastric cancer patients with peritoneal metastasis.
Tumor messenger ribonucleic acid (mRNA) expression levels may have a promising role as potential predictive biomarkers for chemotherapy. Peritoneal carcinomatosis appears to be the most common pattern of metastasis or recurrence and is associated with poor prognosis in gastric cancer patients. Intraperitoneal chemotherapy is widely accepted strategy in the treatment of peritoneal dissemination. In this study, our aim is to evaluate the impact of individualized selection of chemotherapeutics and intraperitoneal combined with system chemotherapy on overall survival, disease free survival, response rate, and safety of advanced gastric cancer patients.
Helicobacter pylori (H.pylori) is a major human pathogenic bacterium in gastric mucosa which is linked to the development of gastritis, peptic ulcer disease, mucosa-associated lymphoid tissue lymphoma and gastric cancer. However the regulatory mechanism of H.pylori-induced immune response is not clear. Long non-coding RNA (lncRNA) has recently emerged as key post-transcriptional regulators of gene expression, differentiation. The investigators had a preliminary results which THRIL (TNFα and hnRNPL related immunoregulatory lincRNA) and PACER(p50-associated COX-2 extragenic RNA) played a potential role in H.pylori induced inflammatory cascade. However, there wasn't a previous study about expression of THRIL, PACER in a human tissue. Therefore, the investigators aimed to evaluate the expression of THRIL, PACER in patients with gastrointestinal disease according to H.pylori infection.
There is no accepted standard therapy for patients with advanced gastric cancer who have progressed during or after second-line therapy. The role of 3rd line treatment in advanced gastric cancer has not been proven. As a novel target of gastric cancer, SMO overexpression is chosen in this study, and the investigators plan this study to evaluate the efficacy and safety of vismodegib in gastric cancer. The doses of vismodegib are based on trials of basal cell carcinoma.
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 purpose of this study is to explore the clinical outcomes of Indocyanine Green Tracer using in laparoscopic gastrectomy with lymph node dissection for gastric adenocarcinoma（cT1-4a, N-/+, M0）.
Gastric cancer has an incidence in North America of over 24,000 new cases annually, of which approximately 15% are diagnosed at an early stage. Standard of care for early gastric cancer (EGC) treatment has historically included anatomical resection with regional lymphadenectomy. However, with the recent emergence of organ-sparing techniques, select patients with a very low risk of lymph node metastases are able to avoid anatomical resection and its inherent short and long term consequences. Despite this advance, EGC patients with high risk features continue to require anatomical resection to achieve adequate lymph node staging, despite the fact that 75-95% of these patients ultimately are found to have node negative disease. Due to the inadequacy of standard imaging modalities to reliably detect nodal metastases in EGC patients, sentinel lymph node sampling for gastric cancer was developed using principals similar to those used broadly for breast and melanoma patients. Early reports from Asia suggest this technique has very high success rates, accuracy and sensitivity, however it has never been verified in a North American context. This study aims to test SLN sampling for North American gastric cancer patients at a high volume regional treatment centre, with an aim to expand the application of organ sparing resection to EGC patients. This project aims to determine the sensitivity and accuracy of sentinel lymph node sampling for early gastric cancer patients at a high volume, North American, tertiary care centre.
