Active clinical trials for "Gastrointestinal Neoplasms"

The purpose of this study is to monitor the success rates and completion rates for endoscopic submucosal dissection (ESD) for gastrointestinal (GI) cancers.

In this prospective, non-randomized cohort study, real-time intraoperative visualization using near-infrared-fluorescence by indocyanine green injection (ICG-NIRF) is performed at two to three time points during procedures of upper GI, lower GI and hepatobiliary surgery with anastomosis formation in open or laparoscopic surgery. Postoperatively, a detailed software-based assessment of each recording is performed to determine the objective ICG-NIRF perfusion rate before and after anastomosis formation, which is then correlated with the 30 day postoperative clinical outcome including occurrence of anastomotic leak.

The purpose of the study is to collect pancreatic tissue, blood and urine from adults to study pancreatic abnormalities.

This is an open label feasibility pilot study of commercially available physical activity monitoring devices in patients receiving systemic therapy at the Harold Simmons Cancer Center, UT Southwestern Medical Center.

The purpose of this study is to identify what makes it easier and what makes it harder to take oral chemotherapy.

To assess the effectiveness of close and intense monitoring on nutritional status of gastrointestinal cancer patients during chemoradiotherapy (CRT), 500 CRT patients diagnosed with gastrointestinal system are going to be recruited into this prospective study. Patient-generated subjective global assessment (PG-SGA) scale and nutrition risk screening (NRS-2002) are used for nutritional assessment at the beginning and the end of CRT; Beside the nutritional parameters, Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30) and gastric cancer module (QLQ-STO22) are used to measure quality of life in patients with gastric cancer while EORTC QLQ-C30 and Colorectal Cancer-Specific Quality of Life Questionnaire (QLQ-CR38) give assessment in colorectal cancer. The acute and late radiation toxicities were evaluated based on Conmon terminology criteria (CTC V3.0) and the toxicity criteria of RTOG/EORTC, respectively. Follow-ups every 3-6 months until three years after chemoradiotherapy are involved. Response Evaluation Criteria in Solid Tumors (RECIST) guidelines are used for response assessment. The primary endpoints are 3-year local control, disease-free survival, distant metastasis and overall survival rate.

The present study investigates the efficacy of a new Endoultrasound guided fine needle biopsy (EUS-FNB) device (AquireTM Boston Scientific= AQUIRE®) for obtaining histological tissue cylinders in the diagnosis of solid pancreatic tumors, submucosal tumors of the upper gastrointestinal tract (esophagus, stomach, duodenum) and lymph node disease..

In our previous study, a nomogram model was established to predict intra-abdominal infectious complications after gastrointestinal surgery. This model was based on the clinical data and the drainage fluid cytokine levels, and it received an AUC >0.9. In this study, validation of this nomogram is planned to be conducted in this prospective cohort study.

This is a retrospective and prospective multicenter registry to collect long-term data (1 year) on patients who have or will undergo Endoscopic resection such as EMR, ESD, EFTR, STER, etc. within the gastrointestinal tract for endoscopic treatment of early gastrointestinal neoplasms involving the resection of the superficial layers, mucosa and submucosa, of the tract wall. Subjects will be consented for medical chart review. The purpose of this retrospective and prospective registry is to assess long term data on efficacy, safety and clinical outcome of Endoscopic Resection within the gastrointestinal tract (1 year). The registry will evaluate efficacy, technical feasibility, clinical outcome, safety profile and overall clinical management through medical chart review. The procedures the investigators are evaluating are all clinically indicated and will not be prescribed to someone to participate in this registry study.

This study was designed to evaluate the efficacy and safety of Extimia® (INN - empegfilgrastim) in reducing the frequency, duration of neutropenia, the incidence of febrile neutropenia and infections caused by febrile neutropenia in patients with High and "Gray Zone" Risk Reccurrence Breast Cancer, Gastointestinal Cancers and Gynecological Malignancies
