Active clinical trials for "Stomach Neoplasms"

The purpose of this study is to investigate the efficacy and safety of intraperitoneal and intravenous paclitaxel plus apatinib and S-1 in the conversion therapy of gastric cancer with positive exfoliative cancer cells

This is a interventional clinical trial to assess the efficacy and safety of combinational therapy of paclitaxel-albumin and S-1 for the neoadjuvant chemotherapy of advanced gastric cancer.

This study is a single center, phase II study, to evaluate the effectiveness and safety of PD-1 Antibody(SHR-1210) Plus apatinib Combined With POF(paclitaxel plus oxaliplatin plus 5-fluorouracil plus leucovorin) , in the first-line treatment for patients with advanced/metastatic gastric cancer.

This study investigates the effect of a combined therapy with gastrectomy and HIPEC in localized advanced gastric cancer.

Study objectives are to investigate the efficacy and safety of activated autologous dendritic cells (DCs) in treatment of gastric cancer. DCs are activated by the proteins from autologous tumor cell membrane and cytokines in vitro. The efficacy endpoints include objective response, immune-cell response, recurrent rate after a radical surgery, progression-free survival and overall survival, and the safety endpoints include adverse events, laboratory tests, ECG, ECOG-PT, etc.

AZD8186 is an orally-dosed, selective Phosphatidylinositol 3-kinase (PI3K) β/δ inhibitor that binds to PI3Kβ and PI3Kδ, and inhibits kinase activity and downstream pathways in vitro and in vivo. AZD8186 has shown significant anti-tumor activity in PTEN-deficient preclinical models, including prostate, triple negative breast cancer, squamous lung and germinal center diffuse large B-cell lymphoma models. PTEN deficiency is reported in approximately 20% of patients with gastric cancer and in 35-48% of those with human epidermal growth factor receptor 2(HER2)-positive gastric cancer. To date, there have been no clinical trials with AZD8186 alone or in combination with paclitaxel in advanced gastric cancer. Therefore, it is very important to conduct clinical trials of combination therapy of AZD8186 and paclitaxel in patients with metastatic/recurrent gastric cancer who have failed previous therapy, and to identify the clinical factors and biomarkers that predict effects of the combination therapy. The purpose of the study is to define the maximal tolerated dose (MTD) and recommended phase 2 dose (RP2D) of paclitaxel and AZD8186 combination therapy in patients with advanced tumors and to evaluate the efficacy of paclitaxel and AZD8186 combination therapy as a second-line therapy in patients with advanced gastric cancer with PTEN aberrations. This study is divided into Phase 1b and Phase 2.

The purpose of this study is to assess the efficacy and safety of Apatinib combined with PD-1 antibody Sintilimab for for Chemotherapy-Refractory Advanced Metastatic Gastric Cancer

This study is to conduct a randomized controlled trial of two kinds of radical gastrectomy for patients with proximal gastric cancer. One is laparoscopic D2 radical total gastrectomy combined with spleen-preserving No.10 lymph node dissection , another one is laparoscopic D2 radical total gastrectomy without clearing the No. 10 lymph nodes of the spleen. We explore the effect of the two procedures on the survival of patients, as well as the surgical complications associated with the two procedures, the number of lymph node dissection, the operation time and the amount of intraoperative blood loss. Furthermore, we also want to discuss the application value of laparoscopic lymph node dissection for spleen preservation in radical gastrectomy for proximal gastric cancer.

Epidural PCA (patient controlled analgesia) for post-operative pain management are effective analgesic method. It is widely used in the postoperative pain management for decades. PCA pumps typically set a fixed basal infusion rate to infuse the analgesics at a constant rate per every hour (conventional mode). In contrast, the newly developed computer-integrated patient-controlled analgesia (CIPCA) mode increases or decreases the basal infusion rate with the use of the patient's bolus button. The CIPCA mode sets the basal infusion rate, the increase / decrease rate of basal rate, and the increment / decrement interval. If the patient presses the bolus button within the set time interval, the set infusion rate is increased because the analgesic is more required. If the bolus button is not pressed during the set time interval, the infusion rate is decreased. Therefore, it can be said that it is an effective method to control the dose of analgesic agent more sensitively to changes in patient's needs and pain.

Gastric cancer is the third major cancer of global cancer-related death. In China, the early diagnosis rate of gastric cancer is relatively low, and most patients are with locally advanced tumor stage. The neoadjuvant chemotherapy (NAC) can bring the survival advantage for gastric cancer patients with locally advanced tumor stage. The primary goal of NAC is to control the micrometastasis and/or progression of the primary lesion in order to improve potential of radical gastrectomy. NAC is recommended for patients with locally advanced stage (T2-4Nx) according to the latest NCCN Gastric Cancer Guidelines. Laparoscopy distal gastrectomy (LDG) can achieve a better postoperative short-term recovery than the traditional open distal gastrectomy (ODG), which can reduce the intraoperative blood loss and to shorten the postoperative hospital stay. Therefore, Enhanced Recovery After Surgery program of gastric cancer surgery recommends the use of minimally invasive surgery. For long-term survival outcomes, there is limited evidence supported that laparoscopic gastrectomy is comparable open gastrectomy. Therefore, due to the lack of high-quality prospective clinical trial results, whether advanced tumor is suitable for laparoscopic surgery is still controversial. Therefore, some multi-center prospective randomized controlled trials have been carried out, compared safety and long-term survival outcome between laparoscopic and open gastrectomy in locally advanced gastric cancer patients. CLASS-01 trials reported that for locally advanced gastric cancers, laparoscopic D2 distal gastrectomy is safe and feasible. Patient's surgical tolerance and stress response may be inhibited after the treatment of NAC. The aim of this trial is to confirm the safety of laparoscopy distal D2 radical gastrectomy for the treatment of after neoadjuvant chemotherapy gastric cancer patients (cT3-4a, N+, M0) in terms of postoperative complications.
