Active clinical trials for "Stomach Neoplasms"

The primary goal of this phase II trial is to evaluate the response rate of combination chemotherapy with S-1 and Irinotecan in patients with advanced gastric cancer as a first-line therapy.

Uncut Roux-en-Y vs Roux-en-Y reconstruction after distal gastrectomy for gastric cancer

Gastric cancer is a common gastrointestinal tumor, and surgical operation is still the main method of gastric cancer treatment. Reported for the first time since 1994, the laparoscopic gastric cancer radical prostatectomy, laparoscopic technique is widely applied in the field of gastrointestinal surgery, has gradually replaced the traditional open operation as the main mode of surgical treatment for gastric cancer. Although laparoscopy has many advantages, there are still disadvantages, such as the discomfort of the physician, the reverse operation, and the ease of shaking, which hinder the application of laparoscopy. In recent years, the Da Vinci robot assisted gastric resection has become a new way to treat gastric cancer. Compared with the traditional laparoscopy and laparotomy, the operation of the robot is more precise and flexible, with obvious advantages of minimally invasive and good application value and prospect. The aim of the study is to compare value (outcomes/costs) of surgery in patients with Gastric Cancer by 3 approaches: open, laparoscopic, and robotic.First of all, the investigators will collect 500 cases of Gastric Cancer patients, randomly assigned for the open, laparoscopic, and robotic group. Secondly, to analyzing the demographic data,basic treatment and follow-up data, including the operation time, blood loss, the number of cut edge positive, the distances of cut edge away from the tumor edge, the cases of anastomotic fistula bleeding, stenosis, average such confinement, the meal time, cost of treatment, tumor recurrence rate, the presence of residual stomach, upset stomach and frequency, reflux esophagitis, bile reflux gastritis and other indicators.

For patients undergoing postoperative therapy for locally advanced gastric cancer after neoadjuvant chemotherapy, we assessed the utility of graded histologic regression of <50% as the criterion of treatment change. Sixty patients will be enrolled to randomize into two groups：receiving modified chemotherapy and receiving the original chemotherapy.

There has been no report on whether the patients with gastric cancer who are also inactive Hepatitis B carriers should receive prophylactic use or preemptive Use of an Anti-viral Drug Entecavir. This open, randomized controlled clinical trial aims to compare the impact of the prophylactic use or preemptive use of an anti-viral drug Entecavir on the outcomes of patients with gastric cancer who are also inactive hepatitis B carriers during chemotherapy and the subsequent follow-ups.

Pembrolizumab is a potent humanized immunoglobulin G4 (IgG4) monoclonal antibody (mAb) with high specificity of binding to the programmed cell death 1 (PD 1) receptor, thus inhibiting its interaction with programmed cell death ligand 1 (PD-L1) and programmed cell death ligand 2 (PD-L2). Olaparib is a potent PARP inhibitor (PARP1, 2, and 3) that is being developed as a monotherapy as well as for combination with chemotherapy, ionizing radiation, and other anti-cancer agents including novel agents and immunotherapy. Paclitaxel is widely used in breast, lung and gastric cancer with every 3-week or weekly cycle. Various targeted anticancer agents have been investigated with paclitaxel and combination with ramucirumab, a monoclonal anti-VEGFR2 antibody, was approved as a 2nd line treatment.

"Mosapride citrate is a 5-hydroxytryptamine 4 receptor agonist, and is widely used as an agent to increase intestinal motility. Mosapride citrate has been demonstrated in in vitro and in vivo studies to increase both gastric and colon motility. In a case-control study of patients undergoing colonectomy, mosapride citrate was found to significantly reduce gas passing and defecation time. Recently, a study reported that mosapride citrate acts on the α7nACh receptor and, consequently, suppresses the inflammatory response of macrophages, thereby suppressing the mechanism that induces paralysis after surgery. To date, this study is intended to analyze whether mosapride citrate significantly affects the improvement of bowel movement after surgery after gastrectomy."

The primary purpose is to compare the remifentanil requirements in deep vs moderate neuromuscular blocks during the surgical pleth index -guided anesthesia in patients undergoing laparoscopic gastrectomy.

In this study, color Doppler ultrasound diagnostic instrument and electronic grip device were used to determine the best grip strength of patients with tumor PICC catheterization, formulate precise and standardized grip strength training guidance for them, provide personalized functional exercise health education, and observe the impact of precise grip strength training guidance on Peripheral central venous catheter-associated thrombosis. To provide a reference for clinical prevention of Peripheral central venous catheter-associated thrombosis in the future.

The aim of this study is to show better postoperative quality of life including lower incidence of dumping syndrome and comparable survival after laparoscopic pylorus preserving gastrectomy (LPPG), compared to laparoscopic distal gastrectomy (LDG) in patients with middle-third early gastric cancer
