Active clinical trials for "Digestive System Neoplasms"

The purpose of the study is to tests the hypothesis, that N-acetylcysteine (a thiol-antioxidant)improves the exercise training effect on cancer patients that experience weight loss (cachexia) as assessed by muscle mass and function as well as histomorphology.

The objective of this study is to assess the efficacy and toxicity of a 3 weekly regimen containing irinotecan combined with capecitabine in the setting of relapsed or refractory upper gastrointestinal tumours. Patients with locally advanced or metastatic adenocarcinoma or squamous cell carcinoma originating from the oesophagus, oesophagogastric junction or stomach who have previously received chemotherapy and have either failed to respond or who have relapsed within 3 months after an initial response will be eligible for treatment in this study. The response rate, failure-free survival and overall survival of treated patients will be evaluated. Toxicity and quality of life will also be monitored closely.

Picoplatin is a new platinum-based chemotherapy drug that has been studied in a variety of cancers. Phase 1 and 2 studies have demonstrated that picoplatin may be effective in patients whose cancer returns or does not improve after treatment with chemotherapy. In these studies, picoplatin was administered intravenously. A capsule containing picoplatin has been formulated. This study will investigate the activity of the oral capsule in humans. Participants with advanced solid tumors will be enrolled.

The primary purpose of this study is to evaluate the safety, side effects, and dosage for Motexafin Gadolinium given with the chemotherapy drug docetaxel to patients with advanced cancers. Secondly, tumor response to the combined treatment, drug levels in the body, and drug interactions will be evaluated.

Gastrointestinal tumours (GITs) are the most common and fatal cancers worldwide; 96% of GITs show the microsatellite-stable (MSS)/proficient mismatch repair (pMMR) phenotype, and these tumours have a poor response to immune checkpoint inhibitor (ICI) therapy. Hyperthermia combined with ICI treatment (HIT) has been reported to show a synergistic sensitisation effect in numerous basic studies. This study aimed to validate the effectiveness, safety, and feasibility of water-filtered infrared A radiation (WIRA) whole-body hyperthermia combined with PD-1 inhibitor therapy and evaluate the real-world clinical application prospects of HIT. This open-label single-arm phase 2 clinical trial aimed to enrol advanced GIT patients with the MSS/pMMR phenotype in the East Asian population who had received third-line or higher treatment. The patients were treated with whole-body hyperthermia on days 1 and 8 of each HIT cycle along with administration of tislelizumab 200 mg on day 2 (24 h after the hyperthermia at day 1). The primary outcome was the disease control rate (DCR), while the secondary outcomes were progression-free survival (PFS), overall survival (OS), safety, and improvement in quality of life.

The incidence of postoperative hypothermia in patients with laparoscopic gastrointestinal tumors is high. Hypothermia increases the risk of postoperative complications and medical costs. Early warning can effectively reduce the incidence of postoperative hypothermia in patients. Multivariate prediction models help identify high-risk patients and reversible factors. At present, there are few reports on the risk factors and prediction models of postoperative hypothermia in patients with laparoscopic gastrointestinal tumors. Therefore, this study aims to clarify the risk factors of postoperative hypothermia in patients with laparoscopic gastrointestinal tumors. Four machine learning algorithms, traditional Logistic regression analysis, decision tree, random forest and naive Bayes, were used to establish risk prediction models. According to the TRIPOD statement, C-index, Hosmer-Lemeshow ( H-L ) test and decision curve analysis ( DCA ) were used to evaluate the prediction and fitting effects of the models in all aspects, and the optimal model was selected and verified. Provide reference for subsequent research.

The objectives of this study are to explore different dosing levels and schedules of entinostat in combination with pembrolizumab in patients with advanced solid tumors, in terms of safety, tolerability, pharmacokinetics (PK), impact on immune correlatives, and efficacy

The purpose of this study is to determine maximum tolerated dose (MTD), dose limiting toxicities (DLT) and recommend a proper dose for our phase II study of S-1 when combined with radiation therapy for locally advanced or recurrent gastric cancer.

To investigate safety and efficacy of single agent sunitinib malate in Chinese Patients With Imatinib Resistant Or Intolerant Malignant Gastrointestinal Stromal Tumor.

There has been no successful treatment of diffuse peritoneal metastasis or carcinomatosis, in childhood tumors. Once this advanced stage of disease is evident, survival is measured in weeks. The selective lethal effect of supranormal temperatures on neoplastic cells and the additive or synergistic effect of combining chemotherapy has been well established in adult clinical trials using continuous hyperthermic peritoneal perfusion (CHPP) for advanced peritoneal adenocarcinoma of gastrointestinal origin, ovarian carcinoma and mesothelioma. This phase I study will evaluate the safety of continuous hyperthermic peritoneal perfusion with escalating doses of intraperitoneal cisplatin in the treatment of children with refractory tumors limited to the abdominal cavity. If tumors are outside the abdominal cavity, the tumors must be able to be controlled. Since CHPP has potential to improve outcome of children with peritoneal and retroperitoneal metastases, this study will evaluate the safety of elevated temperature (40oC) with intraperitoneal cisplatin chemotherapy. Primary Objectives: To determine the MTD and dose-limiting toxicity of intraperitoneal cisplatin given in combination with CHPP as a 90 minute perfusion in children with advanced peritoneal and retroperitoneal solid tumors To determine the safe and tolerable dose of CHPP with cisplatin to be used in Phase II trials To determine the pharmacokinetics of intraperitoneal cisplatin platinum given with CHPP as a 90 minute abdominal perfusion (Optional)
