Filter by:Cryoablation combined with chemotherapy on the quality of life of patients with non resectable esophageal or gastroesophageal cancer.
Rationale: Current standard treatment of localized esophageal cancer (EC) with neoadjuvant chemoradiotherapy (nCRT) followed by esophagectomy with curative intent results in 30% complete, 40-60% partial and 20% no-response at pathologic examination. Clinical response of nCRT is usually evaluated with PET-CT. However, response measurements are currently still insufficient in optimizing EC treatment. Proper pre-surgical response prediction may allow individualized treatment with esophagus-preservation in complete responders or switching to an alternative treatment in non-responders. Interestingly, in many tumors, a subset of cells has been found to possess cancer stem cell (CSC) properties with associated signaling as drivers of tumor (re-)growth and therapy resistance. Response of CSC-derived tissue resembling in vitro cultured tumor organoids may reflect patient's tumors sensitivity to therapy. Objective: To create a patient derived organoid model for EC patients to predict the pathologic tumor response to nCRT in clinical practice. This will allow a more personalized approach in future treatment of locally advanced EC. Study design: Fresh esophageal tumor material will be collected during diagnostic endoscopic ultrasound (EUS) in participating patients. These biopsies will be used to select cancer stem cells, which will be cultured to derive organoids (esophageal cancer patient derived organoids; EC-PDO). When the EC-PDO contain sufficient cells, these cells will be treated with radiotherapy and/or chemotherapy in order to obtain dose-response curves. The response of these EC-PDOs will be compared to the actual tumor response to nCRT treatment in these EC patients, which will be assessed at the definitive pathologic examination of the resection specimen after esophagectomy with curative intent. Study population: All patients with curatively treatable and resectable esophageal cancer (adenocarcinoma or squamous cell carcinoma) can be included in this trial. Main study parameters/endpoints: The main endpoint is response prediction to chemoradiotherapy by EC-PDO; the steepness of the dose response survival curve in the organoids in relation to the pathologic response after resection in the clinical situation. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: The patients will be asked to undergo 3 to 6 additional biopsies during endoscopic ultrasonography (EUS) for the TNM staging of the tumor. The risk of these additional biopsies is not greater than the biopsies for the diagnosis of EC. The patient will not benefit from participation in this trial. For the future approach we can get more insight into the mechanism of (chemo)radiation response or resistance to nCRT, which might lead to a better patient selection and more individualized esophageal cancer treatment in the future. This improvement in selection and treatment can result in less over or under-treatment of these EC patients.
Nasogastric decompression is standard practice after esophageal resection in most centers because it is expected to reduce the incidence of esophagogastric anastomotic leakage by preventing overdistension of the gastric conduit. Most esophageal surgeons have been reluctant to move away from this tradition because of the considerable morbidity of anastomotic leaks after esophagectomy. However, a contrarian view is that the use of prolonged NGD may increase the incidence of postoperative pulmonary complications by promoting aspiration. Considering the numerous complications caused by using the tube and the uncertainty about its usefulness and the scarcity of studies conducted on the subject, particularly in patients with esophageal cancer, the necessity of using the tube in these types of cases is investigated in the present study.
Esophageal cancer is the eighth most common cancer around the world, with more than 450000 new cases per year. Esophagectomy with radical lymphadenectomy (2-field lymphadenectomy) is the mainstay of treatment in many countries for patients with esophageal cancer. To improve the survival, 3-field lymphadenectomy combined with cervical lymphadenectomy was started in 1980s. More potential positive lymph nodes were found during more extended lymphadenectomy, offering more accurate TNM staging, affecting consequent treatment. However，3-field-lymphadenectomy was associated with increased surgical morbidity and mortality. Positron emission tomography (PET) is used for detecting distant metastases and lymphatic involvement. The aim of the study is to evaluate the role of PET in predicting cervical lymph metastases of patients with thoracic esophageal squamous cell carcinoma, and to determine if investigators can use PET to guide future cervical lymphadenectomy.

Prospective, open label, non-controlled single arm, multi-center study The primary objective is to study the effects of the trūFreeze® Spray Cryotherapy System in a population of subjects who have been diagnosed with persistent local esophageal cancer and who are not surgical candidates or have completed or declined systemic therapy.
This study will evaluate if proton beam therapy as part of chemoradiation results in a decrease in diffusion lung capacity of carbon monoxide (DLCO) compared to photon radiation therapy for esophageal carcinoma. A secondary objective is to determine effects on cardiac function, quality of life, and compare acute and late toxicities.
Background: The number of patients with esophageal cancer keeps rising. For many patients, a combination of surgery, chemotherapy, and radiation is necessary to completely treat the disease. Usually, patients receive chemotherapy and radiation at the same time followed by surgery to remove the part of the esophagus with the tumor (Neoadjuvant chemoradiotherapy (nCRT)). Researchers want to learn how to make this treatment more effective. Objective: To see if biopsies before treatment can show which patients will do the best with a combination of chemotherapy, radiation, and surgery. Eligibility: Adults at least 18 years old with esophageal adenocarcinoma or squamous cell carcinoma who should be treated with chemotherapy, radiation, and surgery. Design: Patients will undergo standard testing that is routine for all patients with this disease. These tests include: Medical history Physical exam with activity and nutritional assessment Standard lab tests Imaging studies including a computerized axial tomography (CAT) scan and positron-emission tomography (PET) scan Breathing test into a machine to measure size and function of lungs. Biopsy for a small sample of tumor is removed by esophagogastroduodenoscopy (EGD): A tube inserted into the mouth under anesthesia Endoscopic ultrasound is performed in some but not all patients. Patients will have nCRT at the clinic or with their local doctor. In 6 -12 weeks after nCRT, patients will undergo surgery with: 1. A robotically-assisted, minimally-invasive esophagectomy 2. Or, a traditional, open approach. After surgery, patients are usually in the hospital for 2 weeks and have a feeding tube for at least 2 weeks and potentially longer until they are eating enough to not lose weight. Patients will return for follow-up visits with labs and CAT scans every 6 months for the first two years then every year afterwards.

This study will examine the hypothesis that altered esophageal microbiome leads to the development of esophageal adenocarcinoma (EAC). The aims of the project are, firstly the confirmation of relational data on the study cohort, using the methods developed and applied at the laboratory at University of Queensland Diamantina Institute (UQDI). Second, to generate a tissue microarray resource future tissue in-situ validation of microbes. And finally, to develop a biobank of clinical isolates of relevant esophageal microbes for future functional studies.
This is a phase 1 study to evaluate safety and tolerability of Telomelysin (OBP-301) in combination with radiation therapy in patient with esophageal cancer who are not applicable to standard therapy.
