Filter by:Oesophagogastric cancer is a major cause of cancer related mortality, with an overall 5-year survival rate of 10% worldwide and patients are often diagnosed with locally advanced or metastasized disease at first presentation. For advanced oesophagogastric cancer fluoropyrimidines are the backbone of palliative chemotherapy and is commonly used in 2- or 3-drug combinations . However, in clinical practice after progression on first line therapy, a substantial number of oesophagogastric cancer patients may not be able to start second line chemotherapy due to rapid clinical deterioration. Therefore, new triplets with high anti-tumor activity and low toxicity are urgently needed. Given the activity of capecitabine and oxaliplatin containing regimens and the potential of taxanes in oesophagogastric cancer, the investigators propose a phase I study combining capecitabine and oxaliplatin with Nab-paclitaxel. Solvent-based taxanes (paclitaxel, docetaxel) can cause severe toxicities not only by the active agents itself but also by the solvents like cremophor. Nab-paclitaxel (Abraxane) is a solvent-free formulation of paclitaxel encapsulated in albumin. It does not require premedication with corticosteroids or antihistamines to prevent the risk of solvent-mediated hypersensitivity reactions. This new formulation improves safety profile, allows higher dosing with shorter infusion duration, and produces higher tumor drug concentration. It has proven activity in breast cancer, non small lung cancer and pancreatic cancer, as well as in gastric cancer models.
The current standard treatment of resectable esophageal cancer consists of neoadjuvant chemoradiation followed by resection. However, some patients develop recurrent disease despite chemoradiation and additional (systemic) treatment might have been indicated. Other patients show a (nearly) complete response after chemoradiation and could possibly have been treated with a less extensive treatment regimen. In patients without a threatened circumferential resection margin (CRM) and lymph node metastases chemoradiotherapy could possibly be omitted. Better stratification of patients with esophageal cancer is therefore urgently needed. Functional magnetic resonance imaging techniques (MRI) can provide in vivo, quantitative information on tumor biology and may prove to be a useful non-invasive tool for this purpose. In this project, ultra-small superparamagnetic particles of iron oxide (USPIO) enhanced MRI using ferumoxytol (Rienso®), diffusion weighted MRI (DWI) and T2* MRI will be developed, both in terms of improvement of acquisition and data processing techniques.
In this trial, patients with histologically proven adenocarcinoma of the esophagus or esophagogastric junction noneligible for surgery or chemoradiation with curative intent will be included. Primary objective is to determine the rate of improvement in dysphagia after palliative short course hypofractionated radiotherapy (5 x 4 Gy) followed by chemotherapy consisting of oxaliplatin and fluorouracil. The rate of improvement of dysphagia is evaluated by a 5 graded dysphagia score, and a positive change of at least 1 score is considered to be an improvement.
This survey study is looking to determine if patient reported outcomes(using the PROMIS survey) will vary according to the presence of recurrent or metastatic lung or esophageal cancer.
This descriptive cross sectional study aims to directly compare the diagnostic capability of the probed-based confocal laser endomicroscopy (pCLE) and the magnifying narrow band imaging (M-NBI) in the Lugol's voiding lesions.
Self expandable stent (SEMS) constitutes the main palliative treatment in advanced esophageal cancer. The palliative effect of SEMS is immediate when it comes to relief of dysphagia. The duration of this effect is however questionable. The design of SEMS can be of importance since the device can dislodge and as a consequence of that dysphagia recur. The hypothesis has therefore been formulated that a partially covered SEMS is associated with less tendency to dislocate as compared to those SEMS, recently developed, which are covered through their entire length.
To quantify motion based variation of the target volume of the primary tumor over the course of chemoradiotherapy in esophageal cancer patients, and to use this information to calculate appropriate PTV (planning target volume) margins according to the margins recipe for patients receiving trimodality (neoadjuvant chemoradiation and surgery) or definitive chemoradiation in order to personalize radiation treatment, resulting in either better target coverage or a reduction in normal tissue radiation exposure.
The goal of this clinical research study is to find the highest tolerable dose of LDE225 that can be given in combination with everolimus to patients with esophageal or GEJ cancer. The safety of the drug combination will also be studied.
Esophageal cancer is a highly aggressive malignancy with a poor overall outcome. - Five year survival rate after radical esophagectomy is modest at about 40%.The patients with regional lymph node metastases have worse outcome than those without lymph node metastases. - No standard postoperative adjuvant chemotherapy has ever been established.
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.
