Active clinical trials for "Esophageal Neoplasms"

Vascular endothelial growth factor is expressed in gastric cancer, and expression has been associated with more aggressive clinical disease. Vascular endothelial growth factor expression has been noted in 51% of gastric cancer specimens in one series (versus no expression in normal epithelium or superficial gastritis). Vascular endothelial growth factor expression in resected gastric cancer is associated with tumor recurrence and shorter survival. Maeda et al. studied 95 gastric cancer patients following resection with curative intent, and noted a significantly shorter survival in 34 patients whose tumor endothelium expressed VEGF (as detected via immunohistochemistry) versus 61 patients without endothelial VEGF expression (p<0.05). Yoshikawa and colleagues observed similar survival differences in resected gastric cancer patients based on levels of circulating (plasma) VEGF at time of resection. Circulating VEGF is significantly higher in gastric cancer patients versus those without neoplasia. Elevated circulating VEGF was also associated with shorter survival in a European cohort undergoing gastric cancer resection; there was no survival beyond 30 months in 24 patients with serum VEGF >533 pg/mL versus a 30-month survival rate >35% for 34 patients with VEGF levels below this threshold (p<0.0001, log-rank test). Recently, Jüttner and colleagues noted reduced survival following R0 resection in gastric cancer patients whose tumors expressed VEGF-C or VEGF-D, with the most robust association between expression and reduced survival for patients whose tumors expressed both VEGF-C and VEGF-D. Investigational inhibition of VEGF Receptor 2 in gastric cancer xenografts (TMK-1 cell line) is associated with reduced tumor growth. DC101 therapy in this model is associated with significant reductions in tumor vascularity (as measured by CD-31 expression) and increases in endothelial and tumor apoptosis. The results of the REGARD and RAINBOW studies are consistent with the idea that tumor- related angiogenesis contributes to the pathophysiology of gastric cancer and demonstrate the ability of ramucirumab to represent an improvement in the care of patients with gastric cancer whose disease has progressed after prior chemotherapy.

There is no world-wide consensus on the oncological benefit versus increased morbidity associated with three field lymphadenectomy in patients with esophageal cancer and cervical lymph node metastases. In Asian countries, esophagectomy is commonly combined with a three field lymphadenectomy, including resection of cervical, thoracic and abdominal lymph nodes. However, in Western countries patients with cervical lymph node metastases are generally precluded from curative treatment.

Stage I：preoperative therapy Capecitabine plus oxaliplatin with concurrent radiotherapy is superior to surgery alone ; Stage II: Perioperative therapy Perioperative Capecitabine plus oxaliplatin with Concurrent radiotherapy is superior to adjuvant Capecitabine plus oxaliplatin alone; A regimen of Capecitabine plus oxaliplatin(XELOX) improves survival among patients with incurable locally advanced or metastatic adenocarcinoma of stomach and gastroesophageal cancer . The investigators assessed whether the addition of a perioperative regimen of XELOX regimen with concurrent radiotherapy to adjuvant alone improves R0 resection rate and survival among patients with curable locally advanced adenocarcinoma of stomach and gastroesophageal cancer

The aim is to assess the relative efficacy of S-1 de-escalation therapy vs. continuation of chemotherapy after induction therapy in patients with metastatic esophagogastric cancer in terms of overall survival.

This is a perspective, multicenter,randomized controlled trial to evaluate the efficacy and safety of treatment with CMNa combined with concurrent chemoradiotherapy in patients with locally advanced squamous cell esophageal carcinoma . Analyses of primary objective (ORR) will be done as defined in the protocol.

This study is designed to evaluate the efficacy and safety of icotinib in treating advanced carcinoma of the gastroesophageal junction and esophagus with EGFR overexpression (IHC 3+) or positive FISH, the primary endpoint is objective response rates.

This is an open label, single-arm phase II, multi-institutional trial to evaluate the efficacy and safety of the combination of nab-paclitaxel and FOLFOX (FOLFOX-A) as first line therapy for patients diagnosed with histologically-confirmed advanced gastric/GEJ adenocarcinoma.

The goal of this clinical research study is to learn if giving chemotherapy and radiation therapy before surgery for early-stage esophageal cancer can help to control the disease and if so, for how long. The safety of this treatment will also be studied.

The primary objective of this study is to assess the efficacy of nimotuzumab in combination with chemotherapy and radiotherapy for the treatment of locally advanced esophageal cancer, comparing it to that of the conventional treatment with radiation and chemotherapy. The secondary objective of this study is to assess the health-related quality of life for the nimotuzumab in combination with chemotherapy and radiotherapy regimen, compared to the standard chemoradiation regimen in the treatment of inoperable locally advanced esophageal cancer.

The purpose of this study is to determine the efficacy of catumaxomab by determination of the rate of macroscopic complete remissions of peritoneal carcinomatosis after treatment with one cycle (four doses) of catumaxomab followed by six cycles of routine neoadjuvant chemotherapy.
