Active clinical trials for "Digestive System Neoplasms"

Transarterial chemoembolization (TACE) is widely used for unresectable hepatocellular carcinoma (HCC). However, the hypoxia caused by TACE in surviving tumor cell leads to release of angiogenic and growth factors contributing to poor outcome. Sorafenib can block tumor cell proliferation and angiogenesis. The hypothesis is that patients with unresectable HCC may benefit from sorafenib in combination with TACE.

Endoscopic submucosal dissection (ESD) is a newly developed technique in the field of endoscopic treatment for GI neoplasms, because of its high rate of en bloc resection. The purpose of this study is to evaluate the efficacy and safety of ESD for GI neoplasms.

Surgery for digestive cancers is managed according to quality standards, validated by the scientific community. Despite the diffusion of these standards through the benchmarks of good practice, the results of the surgery remain disparate. In many countries, this "inequality of opportunity" has justified the establishment of quality assurance systems to measure the results of surgery for one or more localizations of digestive cancer. These surgical audit experiments have shown a positive, rapid and cost-effective impact on complication rates, recurrence rates and overall survival even in the absence of interventional measures. The data collected also helped to improve the management of subgroups of patients usually excluded from clinical trials. In Morocco, the National Cancer Prevention and Control Plan provides for the establishment of a quality assurance system with the introduction of a system for monitoring and evaluating the care of patients. This pilot project is part of this framework, for the group of patients who are candidates for surgery for digestive cancers.

The primary purpose of this study is to determine the non-inferiority of overall survival FOLFIRI with or without Bevacizumab compared with Irinotecan (CPT-11) with or without Bevacizumab as Second-line therapy in Patient with Metastatic Colorectal Cancer.

Clinical treatment of digestive tract tumor patients often need chemotherapy before and after operation, most chemotherapy drugs will cause harm to patients, prone to leakage, leading to tissue necrosis. The construction of deep venous channels can protect the blood vessels of patients and reduce their pain. PICC and PORT have become a new clinical treatment technology, and have become the mainstream mode of long-term intravenous indwelling. Although the central venous catheterization technology has many advantages, it also has some limitations. Because of its long-term existence, periodic nursing needs to be carried out, such as correct flushing, sealing, replacement of film and so on. Incorrect care or failure to come to the hospital on time may lead to abnormal use of the catheter or shortening of service life, resulting in some unexpected pain. Under the influence of COVID-19 's epidemic situation, it becomes more difficult and unrealistic for patients to come to hospital regularly for nursing. During the epidemic, patients need more safe and effective care at home. In order to help patients with good central venous catheter nursing at home, this study intends to apply remote professional real-time guidance technology to home nursing care of PICC and PORT tumor patients. Through on-site practical operation training, video explanation materials of long-distance on-line decomposition steps and real-time telephone audio connection guidance are provided to enable patients' families to quickly learn to master nursing techniques, so as to achieve safe and effective self-care at home.

Patients accepted laparoscopic radical operation for carcinoma of colon and upper middle section of the rectum will be as the research object. Cancer patients are diagnosed based on pathology or cell biology. The trial is randomized, parallel and open. They are randomized into 2 groups: both groups receive surgery. The experimental group receives conventional treatment combine with electroacupuncture Zusanli point .etc finish operation and the contrast receives the same conventional treatment with experimental group. Clinical evaluation includes gastrointestinal tract recovery of function, pain relief, life quality improvement. Blood biochemistry tests mainly include gastrin(GAS), stress related hormone, peroxidatic reaction and the ratio of immune cells.

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).

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.
