Filter by:An open, single-center, randomized controlled phase II clinical trial to compare the efficacy and safety of conformal intensity modulated radiation therapy (IMRT) combined with carboplatin and IMRT combined with carboplatin and 5-FU in elderly patients with locally advanced esophageal squamous cell carcinoma at high risk of chemotherapy
A one-group prospective cohort study design with measures collected pre- and post-intervention. The primary goal of this study is to evaluate the effect of a multimodal prehabilitation preoperative program on changes in frailty in upper gastrointestinal surgical oncology patients.
This phase I trial is to investigate the safety and the possible side effects of bi-specific antibody armed T-cell therapy when given together with low-dose IL-2 in treating patients with Her2-positive neoplasms of digestive system. Expanded autologues T cells that have been coated with bi-specific antibodies, such as anti-CD3 and anti-human epidermal growth factor receptor 2 (HER2), may stimulate the immune system in different ways and stop tumor cells from growing. Interleukin-2 may stimulate white blood cells to kill tumor cells.
Aim 1: To develop a prospective tissue and blood biorepository from patients with a history of Barrett's Esophagus (BE) or esophageal cancer (ECA) presenting to UNC hospitals for routine care upper endoscopy for their condition. Aim 2: To collect clinical data from patients with a history of Barrett's Esophagus (BE) or esophageal cancer (ECA) that includes demographic data, endoscopic procedure data, and pathology data. Aim 3: To integrate Aim 1 and 2 in a manner that will provide an efficient bi-directional flow of clinical information and specimens between laboratory and clinical scientists in order to foster innovative translational research. Aim 4: To create a biorepository for future Institutional Review Board (IRB) approved studies that have tissue and/or blood specimen component.
Two large, nutritional intervention trials were conducted in Linxian, China between 1985-1991. These trials tested the effect of multiple vitamins and minerals in the prevention of esophageal cancer in a population with the highest known rate for this disease in the world. Results from the trials showed that Beta-carotene + Vitamin E + selenium reduced total mortality, total cancer mortality, and stomach cancer incidence and mortality. Multivitamins/minerals also showed reduction in premalignant lesions. Preliminary follow-up data obtained for the time period after cessation of intervention in 1991 suggests that the observed benefit for total and cancer mortality is reduced but that the benefit for stomach cancer remains. The objectives of the follow-up study are: (1) to continue to determine cancer incidence and all causes of mortality in trial participants after intervention to permit examination of potential effects of the interventions on total and cause-specific mortality and cancer incidence in the post-intervention period; (2) to conduct a cross-sectional nutritional survey in a subsample of living trial participants to evaluate their nutritional status, asses the validity of dietary questionnaires, and relate neurologic status to vitamin B12 plasma levels; (3) to collect a blood sample from all living trial participants to permit further etiologic investigations of genetic and environmental hypotheses; and (4) to perform nested case-control studies of selected genetic and environmental hypotheses. To accomplish the objectives of the follow-up study, we will: (1) determine updated vital status and cancer status data on all trial participants via monthly checks of village doctor records and quarterly checks of the Linxian Cancer Registry; conduct a Vital/Cancer Status Interview Survey among all (n-34,000 trial participants (or their surrogates); identify, collect, and store all available diagnostic materials for trial participants identified as having developed cancer or died with cancer during the follow-up period; (2) conduct a Nutritional Survey on a subsample (n-1000) of living trial participants that will include (a) a physical exam and brief medical history, (b) a neurologic history, (c) a cognitive function exam, (d) a hair/mouth skin exam, (e) a neurological exam, (f) a nutritional questionnaire, and (g) collection of a blood sample for hematologic/biochemical analyses; (3) conduct a Blood Collection Survey of all living trial participants (n-23,000) to obtain (a) a physical exam and brief medical history and (b) a single 10-ml blood sample for separation and preservation as WBCs (both viable and nonviable), RBCs, and plasma for genetic (e.g., xenobiotic polymorphisms) and environmental (e.g., plasma ascorbic acid) hypothesis testing; and (4) perform Nested Case-Control Studies of selected genetic and environmental hypothesis related to the etiology and prevention of esophageal cancer and stroke. These will be done using serum from the new cancer and stroke cases (-2500) and controls (-2500) previously identified from 1991-1996, as well as using new cancer and stroke cases and controls for the period 1996-2004 (-9000). The followup for endpoints will continue monthly for an additional 5 years (through the year 2003). The Nutritional Survey and Blood Collection Survey will be conducted in the spring of 1999. The Nested Case-Control studies will be performed annually beginning in 2000, and the Vital/Cancer Interview Survey will be conducted in the Spring of 2001.
