Filter by:The purpose of this study is to to investigate the feasibility and safety of fast-track surgery when combined with laparoscopic-assisted gastrectomy for advanced gastric cancer patients.
This phase II trial aimed to assess the efficacy and safety of pemetrexed in patients with pretreated metastatic gastric cancer.
It is recognized that gastroscopy can miss intestinal metaplasia, dysplasia and early gastric cancer. This could conceivably be due to the fact that these lesions may only present as subtle mucosal changes on conventional white light endoscopy (WLE) and thus be easily missed. In narrow band imaging (NBI) a rotating interference narrow band filter is interposed after the xenon light source such that when the NBI mode is switched on, discrete blue and green wavelengths are used and this improves mucosal surface contrast and facilitates visualization of mucosal details. A new NBI system is available that allows brighter illumination. We hypothesize that bright -NBI is superior to WLE in detecting focal gastric lesions such as gastric intestinal metaplasia, dysplasia and early gastric cancer in subjects undergoing gastroscopy.
Enhanced Recovery After Surgery (ERAS) programs have been introduced with purposes of reducing the surgical stress response and obtaining optimal recovery after surgery.
multicenter, open label, randomaized, phase III The role of post surgery adjuvant chemotherapy is becoming more and more important in AGC (advance gastric cancer). S-1 and combined therapy of Capecitabine and Oxaliplatin are currently accepted as a standard therapy among the AGC patients who were performed gastrectomy from the D2 surgery. However, many improvements will be needed in stage IIIB and IV. Combined chemotherapy of Docetaxel, Capecitabine, and Oxaliplatin may be considered as one of the best treatments for IIB and IV(M0) stage AGC patients who were performed gastrectomy.
40 eligible patients with confirmed esophageal or gastric adenocarcinoma and anemia will be randomized to a control or intervention group for management of this anemia. The control group treatment will consist of standard treatments as governed by the clinical team (eg oral iron, blood transfusions) whilst the intervention group will be treated with intravenous iron III isomaltoside (Monofer ®). It is hypothesized that intravenous iron supplementation is more efficacious than standard therapies.
By literature review, there is a clear trend towards a potential role for human epidermal growth factor receptor 2 (HER2) as a negative prognostic factor in gastric cancer was shown, but only in half of the analyses used multivariate statistics. Besides, For the studies in the current review that have looked at the Lauren classification in relation to HER2, a higher level of overexpression or amplification was found in the intestinal phenotype compared to the diffuse or mixed types. As lauren classification was reported as an independent prognostic factor result in favored outcomes in gastric cancer (GC), there may probably be histologic bias exists when compare overall survival (OS) between HER2 statuses without controlling this confounding. Similarly, patients with different disease settings (early stage and advanced stage; resectable and metastatic) affect outcomes either. In this study, the investigators will retrospectively analyze HER2 status and lauren classification in 800 gastric patients who received gastrectomy in the Cancer Center of Sun Yat-Sen University between January 1996 and December 2006 with formalin-fixed and paraffin- embedded tumor tissue samples. To avoid potential influence by histologic classifications and disease settings, the investigators assess difference in OS between HER2 positive and HER2 negative groups in resectable Lauren classification of GCs, and further evaluate the prognostic value of HER2 status according to tumor-node-metastasis (TNM) stages.
Lymph node dissection in gastric cancer surgery is a very important factor not only for exact acquisition of stage but also proper treatment. Realistically, it is impossible to identify complete removal of lymph node in dissected nodal station by naked eye. The investigators can assess the route of lymphatic drainage and identify residual lymph nodes in dissected area. In the field of gastric cancer treatment, ICG and near infra-red fluorescence imaging was used only detection of sentinel lymph nodes. However, this novel concept can help to understand lymphatic drainage and make surgeons to perform D1+ or D2 lymph node dissection completely.
Gastric cancer remains a significant global public health problem. Although in developed countries its incidence has dramatically decreased, on a worldwide scale it is still a leading cause of cancer-related deaths. Surgery is the only potentially curative treatment for gastric cancer. Although the survival rates for patients with early stage disease (stage 1A and 1B) are good, this subgroup of patients constitutes only 20% of those undergoing resection. The majority of patients will have locally advanced or metastatic disease at presentation, which has an extremely poor prognosis. The current five-year survival rate for gastric cancer in Western countries is approximately 20-30%, a figure that has improved little over the past 30 years. The intervention arm in TOPGEAR consists of pre-operative chemotherapy, pre-operative chemoradiotherapy, surgery and post-operative chemotherapy. The control arm consists of pre-operative chemotherapy, surgery and post-operative chemotherapy. The primary objective of TOPGEAR is to investigate whether the addition of chemoradiotherapy to chemotherapy is superior to chemotherapy alone in the neoadjuvant setting by improving pathological complete response rates in the first instance, and subsequently overall survival, in patients undergoing adequate surgery (D1+ dissection) for resectable gastric cancer.
This study is a phase III, multi-centre study of olaparib in combination with paclitaxel, compared with placebo in combination with paclitaxel in patients with advanced gastric cancer who have progressed following first-line therapy. Patients will be from China, Japan , Korea and Taiwan.
