Active clinical trials for "Stomach Neoplasms"

The objective of the study is to assess the value of PET/CT in diagnosis, staging, response evaluation, and relapse monitoring of gastric cancer.

Compare with the gastric cavity without cancerous transformation in atrophic gastritis, analyze the microbiota and metabolomics changes in intestinal type of gastric cancer under the background of atrophic gastritis, and explore the relevant mechanisms.

This pilot clinical trial studies an electronic monitoring device of patient-reported outcomes (PROs) and function in improving patient-centered care in patients with gastrointestinal cancer undergoing surgery. Electronic monitoring is a technology-based way of asking patients about the quality of life, symptoms, and activity using online surveys and an activity tracking watch may make it easier for patients to tell their doctors and nurses about any issues before and after surgery. Electronic systems of assessing PROs may increase the depth and accuracy of available clinical data, save administrative time, prompt early intervention that improves the patient experience, foster patient-provider communication, improve patient safety, and enhance the consistency of data collection across multiple sites.

This randomized pilot trial studies how well two supportive programs work for improving fatigue and depressive symptoms in patients with GI undergoing chemotherapy. Possible mediators such as psychological stress, circadian disruption, and inflammation, will also be explored.

This study aims to assess the impact of preoperative oral carbohydrate drink on gastric emptying and PH of gastric fluid in gastric cancer patients directly. Furthermore, investigators aim to evaluate the safety and effectiveness of preoperative oral carbohydrate in elective gastric cancer surgery, providing direct evidence for clinical practice.

Surgery is the cornerstone of treatment for patients with oesophageal or gastric cancer, but while surgical removal of the tumour (oesophagectomy or gastrectomy) may offer the best chance of cure, these are major operations associated with specific long term complications. Weight loss and poor nutrition are relatively common problems among patients who attain long-term cancer remission and cure after surgery. The mechanisms underlying these problems are not well understood and therefore treatment options are limited. The investigators research has demonstrated increased levels of chemical messengers (gut hormones) released from the gastrointestinal tract after meals in patients who have previously undergone upper gastrointestinal surgery. These chemical messengers play a role in signalling the feeling of fullness during and after a meal (satiety). Understanding the mechanisms involved in increased gut hormone secretion after these operations may allow us to use certain medications to block gut hormone release and hence reduce satiety allowing patients to eat more, regain weight and prevent nutritional complications after surgery. Exaggerated post-prandial satiety gut hormone responses following oesophagectomy have, however, only been established cross-sectionally and therefore the time course for development of increased gut hormone secretion is unknown. Data collected from this study will provide important information about optimal timing of therapeutic intervention in this patient group, while offering mechanistic insights with regard to the pathophysiologic process underlying post-operative early satiety.

The purpose of this study is to find the elderly patients with laparoscopic gastric cancer radical is suitable the BIS closed round target control level of anesthesia depth of sedation, can decrease the elderly laparoscopic gastric cancer radical surgery in patients with perioperative inflammatory reaction, and reduce the incidence of perioperative pulmonary complications such as, for elderly patients with gastric cancer radical perioperative inflammation control to provide the reference and provide guidance for clinical anesthesia work.

Title: The role of early systematic best palliative care versus on request palliative care consultation during standard oncologic treatment for patients with advanced gastric or pancreatic cancers: a randomized, controlled, multicenter trial. Description of Study Treatment: Interventional arm Patients will receive standard oncologic care and will be assigned to early systematic best palliative care. They will meet a member of the palliative care team within 2 weeks after enrolment. Thereafter, they shall be visited by a palliative care team member every 2 weeks until death. Patients assigned to this experimental arm will be evaluated if the total of palliative care visits between T0 (day of enrollment) and T1 (12±3 weeks) is ≥3. Palliative care visits and intervention has to be oriented by the General guidelines for palliative care: specific attention will be paid to assessing physical and psychosocial symptoms, establishing goals of care, assisting decision making regarding treatment, and coordinating care on the basis of the individual needs of the patients. The doctor expert in palliative care, with regular visits in the experimental arm, must be a physician dedicated full time to palliative care, that can directly prescribe drugs and other interventions, and with a particular attention to physical, psychological, and spiritual needs. Palliative care doctor must have the possibility to decide about organizational arrangements. He has to perform the palliative care visit according to Temel indications. Standard arm Patients will receive standard oncologic care and will be assigned to on request palliative care consultation. They will be not scheduled to meet with the palliative care service unless a meeting will be requested by the patients, the family, or the oncologist. After the time of evaluation (T1) patients will be followed by the palliative care services as needed. Patient completes QoL (Quality of Life) and mood questionnaires at baseline and at 12 weeks ± 3. Patients will receive standard antineoplastic treatment in both arms of the study according to best clinical practice in each participating centre.

The use of epidural dexmedetomidine decreases the anaesthetic requirements and improved postoperative pain. Dexmedetomidine is a potent and highly selective a2-adrenoceptor agonist and has sympatholytic effect. Power spectral analysis of heart rate variability(HRV) is a useful tool to assess cardiac autonomic activity. We investigated whether preemptive epidural dexmedetomidine can develop hemodynamic change and it could be identify patients by HRV.

A Phase I trial of Induction chemotherapy and Chemoradiotherapy with TS-1 and Cisplatin (SP) as first-line treatment in patients with high risk advanced gastric cancer. Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving chemotherapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Radiation therapy was effectively used in esophageal cancer, laryngeal cancer and rectal cancer, but gastric cancer are rarely studied in Korea. There is an increasing interest in preoperative radiotherapy in effort to improve survival and increase pathologic complete response in patients with gastric cancer. Chemoradiotherapy may be the best modality in the neoadjuvant setting for high-risk advanced tumors, such as type IV or large type III, N3/bulky N2 metastasis, or locally advanced tumors.
