Active clinical trials for "Gastrointestinal Neoplasms"

The purpose of this study is to evaluate the efficacy of autologous tumor lysate-pulsed dendritic and cytokine-induced killer cells (DC-CIK) for colorectal cancer (CRC).

In this study, the relationship between DPD and the effects of S-1 combined with oxaliplatin chemotherapy were investigated in 200 patients with gastrointestinal carcinoma.

The clinical trail of electroacupuncture combined with oxaliplatin regimen on gastrointestinal carcinoma.This trail is randomized controled.Patients are diagnosed gastrointestinal cancer based on pathology or cell biology.They are randomized into 2 groups:both groups receive Oxaliplatin regimen.The treatment group receives electroacupuncture in addition to the chemotherapy.The control group only receive the same chemotherapy with the treatment group.Both group have the same adjuvant therapy.

This phase I trial collects blood samples to investigate the prevalence of changes in genes (genetic mutations) in solid tumor patient populations seeking care at Mayo Clinic Embedded Cancer Center at St. Vincent's Riverside. This may help doctors better understand and/or treat others who have genetic mutations.

This multicenter, prospective, interventional study aims to include 2000 gastroscopic procedures and investigate the relationship between procedure time and lesion detection rate in tertiary endoscopic centers in China. At the first stage, the researchers observe the actual procedure time of gastroscopies without affecting the natural behavior of endoscopists. At the second stage, a minimal time limit will be set for each procedure based on the observational results of the first stage. The primary study outcome is focal lesion detection rate. Secondary outcomes include detection rate of early upper GI cancer, biopsy rate and adverse event rate.

The objective of the SIM trial is to investigate whether using the Surefire Infusion System during holmium-166 radioembolization increases the posttreatment tumor to non-tumor activity concentration ratio, compared with using a standard end-hole microcatheter.

This study evaluates the impact of Endorings™ assisted colonoscopy on the number of polyps detected per patient compared to standard colonoscopy without use of EndoRings™. Half of the participants will receive EndoRings™ assisted colonoscopy, while the other half will receive standard colonoscopy.

Evaluation of DC-CIK cells combined TACE treatment for HCC

Hypothesis: Different patients have different biomarkers, if doctors know about the biomarkers of patients; they may be able to prescribe a regimen that is better suited to the patient's specific needs. This is a pilot study. Here, we used whole exon sequencing and Integrated genomic network analysis to identify the biomarker or gene. We aimed to learn if the drug chosen based on biomarkers can help to control metastatic gastrointestinal cancer who had failed from all standard and available regimens.

This is a single-center randomized, placebo-controlled, double-blind feasibility study comparing the intervention of perioperative nutritional supplements (immunomodulation, carbohydrate loading, and protein isolate) with an identical placebo for each solution in patients with gastrointestinal cancer undergoing surgery. Eligible and consenting patients will be randomly allocated to receive the intervention or placebo in a 1:1 ratio. This study will assess the feasibility of a large, multi-centre trial by establishing the feasibility of randomization to intervention or placebo. This study will be conducted at the Juravinski Hospital and will enroll 100 patients over 18 months. The study intervention includes three perioperative nutritional supplements: (1) a protein supplement administered 3 times a day for 30 days before surgery, (2) a sugar-based supplement administered the day prior to and the day of surgery, and (3) a formulated liquid diet containing arginine, RNA, proteins and omega-6 fatty acids (referred to as immunonutrition for the purposes of this study) administered for 5 days prior to and 5 days after surgery. The primary outcome for each eligible patient is defined as being randomized to intervention or placebo. The criteria for success of this study is defined as the proportion of eligible patients randomized as ≥ 60%. If the estimated proportion is <40%, the trial will be considered not feasible. If the proportion is between 40%-59%, the trial will be considered feasible with modifications to improve enrolment. Other secondary objectives include compliance with study intervention, estimating differences in postoperative complications, length of hospital stay, and quality of life between groups.
