Filter by:This proposed collection of primary tumor cells lines will benefit esophageal cancer research within the University Health Network. This collection of gastro-esophageal tumor samples will be used to grow primary tumor cell lines, which will provide researchers with ready samples of various gastro-esophageal cancers. This will help to address the issue of access to these cell lines due to the limited number of patients with gastro-esophageal tumors, and high rates of contamination.
The primary purpose of this study is to test new methods to diagnose BE in time before it turns into advanced cancer. Once BE is diagnosed, the current standard of care is to monitor the disease so that complication such as cancer can be diagnosed early. The two new methods the investigators are evaluating are: a) blood test and b) brush test of the food pipe. The investigators will collect blood, bile and cells from the food pipe and stomach and measure for a biomarker called microRNA (miRNA). In the future, measurements of microRNA biomarkers could help the doctors figure out which patients are at increased risk for cancer of the esophagus.
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.
Background: Autologous T cells engineered to express a T cell receptor (TCR) targeting NY-ESO-1 will be infused back to patients with NY-ESO-1- expressing malignancies. The patients pretreated with a lymphodepleting preconditioning regimen will be monitored after infusion of anti-NY-ESO-1 TCR-transduced T cells for adverse events, persistence of anti-NY-ESO-1 TCR-transduced T cells and treatment efficacy. Objectives: To evaluate the safety and the efficacy of anti-NY-ESO-1 TCR-transduced T cell-based immunotherapy for patients with NY-ESO-1- expressing malignancies. Eligibility: Patients older than one year of age, who have relapsed or refractory malignancies that express both NY-ESO-1 and human leukocyte antigen (HLA)-A2 molecules. Patients must have adequate organ functions. Design: - Peripheral blood from patients will be collected for isolation of peripheral blood mononuclear cells (PBMCs), which will be transduced with a lentiviral or retroviral vector encoding an HLA-A2 restricted anti-NY-ESO-1 TCR gene. - Patients will receive a lymphodepleting preconditioning regimen to prepare their immune system to accept modified T cells. - Patients will receive an infusion of their own modified T cells. They will remain in the hospital to be monitored for adverse events until they have recovered from the treatment. - Patients will have frequent follow-up visits to monitor the persistence of modified T cells and efficacy of the treatment.
Motive: In order to improve the treatment technique, a comprehensive follow-up program is needed to obtain all relevant patient, treatment and toxicity data from esophageal cancer patients. Goal: To set-up and maintain a database containing treatment results in terms of tumor control, side effects, complications and patient-reported quality of life. A standard database of patients receiving photon treatment will be created. These data are then linked to dose-volume data of radiotherapy, with the aim to build prediction models for both tumor control and toxicity after radio (chemo) therapy that can later be used for selecting patients for proton treatment.
Esophageal carcinoma is an aggressive malignant disease with poor prognosis. Surgical resection remains the most effective method for this malignancy. Although different approaches have been studied for the surgical resection of thoracic esophageal cancer, little evidence has been achieved due to lack of large scale multicenter randomized trials with regard to this issue: whether left transthoracic approach or right transthoracic approach is the optimal surgical approach for treating middle and lower thoracic esophageal cancer without upper mediastinal lymph node metastasis. The purpose of this study is to compare the postoperative local recurrence rate and long-term outcome of esophagectomy through left and right transthoracic approach in the middle and lower thoracic esophageal cancer patients without preoperative upper mediastinal lymph node metastasis.
Esophageal carcinoma is an aggressive malignancy with poor prognosis. Surgical resection remains the most effective method for this malignant disease. VATS esophagectomy has become more and more popular in China and around the world. Although VATS esophagectomy has been proven to be effective in preventing respiratory complications, there is still no ample evidences to demonstrate that VATS esophagectomy is as effective as traditional three-incision esophagectomy in lymph node dissection and is equal or superior in long-term survival. The purpose of this large scale prospective observational study is to compare the minimally invasive thorascopic/laparoscopic esophagectomy with traditional three-incision esophagectomy in lymph node dissection, postoperative recovery, postoperative complications, and long-term survival.
The purpose of this study is to compare the lymph node dissection results and prognosis in thoracic esophageal carcinoma patients without cervical lymph node involvement by preoperative CT and/or ultrasound treated by two-field lymphadenectomy or three-field lymphadenectomy.Another purpose of this study is to clarify whether the lymph node along the right recurrent laryngeal nerve can be taken as the sentinel lymph node which is able to indicate neck lymph node metastasis and necessity for three-field lymphadenectomy.
Esophageal cancer (EC) is the eighth most common cancer and the sixth leading cause of cancer deaths worldwide. Minimally invasive esophagectomy (MIE) is regarded as a safe and effective management for resectable EC. Gastric tube is considered to be an ideal substitute for the resected esophagus, and used for cervical esophagogastric anastomoses for digestive tract reconstruction in MIE. However, the tension at the anastomosed area can not be ignored and may cause cervical anastomotic leakage (CAL) in some cases. Continuous neck flexion is a standard post-operative posture after tracheal resection and reconstruction, and aimed to relieve the anastomotic tension. In this study, the investigators attempt to adopt the maneuver in MIE, and observe its effect on relieving the anastomotic tension and decreasing the incidence of CAL.
Esophageal cancer is the sixth leading cause of cancer death in worldwide. Over the past 2 decades, well-designed clinical trials have documented the clinical benefits of combination of chemotherapy and radiation for localized esophageal cancer, either as primary therapy or in neoadjuvant setting. Paclitaxel, a radiation sensitizer, has important single-agent activity in esophageal cancer. Paclitaxel-based chemoradiation has been the framework for the recent Radiation Therapy Oncology Group (RTOG) trials of nonoperative management of esophageal cancer. Accumulating clinical evidence suggests that Epidermal Growth Factor Receptor (EGFR) represents a viable target in the treatment of esophageal cancer. EGFR expression is associated with poor prognosis. Nimotuzumab binds specifically to EGFR on both normal and tumor cells and competitively inhibits the binding of Epidermal Growth Factor (EGF) and other ligands, such as Transforming Growth Factor-α (TGF-α). Preclinical models have suggested synergy between nimotuzumab, paclitaxel, cisplatin and radiation. For our phase II study in locally advanced esophageal squamous cell carcinoma (ESCC), the combination of cetuximab and chemoradiotherapy has demonstrated both response and survival benefits. Myara et al reported that nimotuzumab plus concurrent chemoradiation therapy (CCRT) was safe and provided statistically significant objective response (47.8%) and disease control rate (60.9%) in nonresectable ESCC. With all these, the investigators plan to study phase III trial.
