Active clinical trials for "Stomach Neoplasms"

Prospective Randomized Controlled Multicenter Clinical Trial for Comparison of Safety Between Totally Laparoscopic Distal Gastrectomy(TLDG) and Laparoscopy-Assisted Distal Gastrectomy(LADG) With Billroth-II Reconstruction and D2 Lymphadenectomy for Locally Advanced Gastric Cancer

Purpose: This aim of the study is to evaluate the efficacy and safety of neoadjuvant chemotherapy with the modified FOLFOX6(mFOLFOX6) regimen and its impact on survival on a series in local advanced gastric cancer patients. Patients and methods: The study is a prospective non-randomized study. Patients with histopathologically confirmed and locally advanced gastric cancer(T2-T4 or N+) are enrolled in the study. Patients are given mFOLFOX6 scheme for 3 cycles.A radical gastrectomy and a D2 lymphadenectomy was will be scheduled 3-6 weeks after the completion of the preoperative chemotherapy. Down-staging is assessed comparing pretreatment clinical staging with postoperative pathologic staging on patients who underwent radical surgery. Tumor down-staging and the grade of pathologic response are included in a statistical correlation between tumor regression induced by mFOLFOX6 neoadjuvant chemotherapy and survival.The primary endpoint is 3-year overall survival, secondary endpoints are disease-free survival, R0 resection rate, toxicity and prediction of response.

In this study, safety and effects of MUC1-gene-DC-CTL and MUC1-peptide-DC-CTL on human gastric cancer are going to be investigated.

Designed as a single arm multi-center prospective phase II trial, which evaluates the number of dissected lymph nodes in the N2-area as a surrogate parameter for adequate D2 lymphadenectomy in robotic distal gastrectomy (RDG) for clinical stage II or III gastric cancer.

The choice of neoadjuvant chemotherapy regimen for locally advanced gastric cancer is controversial. The aim of this study was to compare the short- and long-term outcomes of XELOX regimen with Docetaxel, S1 and oxaliplatin regimen as neoadjuvant chemotherapy regimen for locally advanced gastric cancer. The objective of this study is to determine what kind of neoadjuvant chemotherapy strategy can make subsequent radical surgery feasible and improve overall survival in patients with locally advanced gastric cancer.

Gastrointestinal(GI) hemorrhage related with gastric cancer is prevalent in advanced cases mostly. As endoscopic hemostatic methods such as argon plasma ablation (APC) had developed, controlling GI hemorrhage in gastric cancer is much easier these days. but re-bleeding rate is still high, even after successful hemostasis with APC or electrical coagulation. Furthermore patients who were experienced re-bleeding are expected poorer survival outcomes than those who are not. So excellent bleeding control in gastric cancer is most important in GI hemorrhage of gastric cancer. Recently developed hemostatic powder [Endo-Clot(TM)] is easy to use and have proven its usefulness in GI hemorrhage in peptic ulcer diseases. So in this study, investigator will try to find out feasibility & safety of Endo-Clot(TM) in GI hemorrhage in gastric cancer.

The combination of Cisplatin and S-1 (CS) achieved a response rate of approximately 45% with the PFS being around 6 months and overall survival time being 13 months in Japanese and Chinese gastric patients. It remains unclear whether the addition of docetaxel to CS would further enhance the efficacy as it dose in DCF(docetaxel, cisplatin and 5-fluorouracil). This is a single center, phase II clinical trial to evaluate the efficacy of docetaxel, cisplatin and S-1 (DCS) as first line chemotherapy for patients with advanced gastric and gastroesophageal junction cancer.

The purpose of this study is to evaluate and compare safety and effectiveness of Chemotherapy in Paclitaxel plus raltitrexed plug compare with taxol second-line treatment for advanced gastric cancer

Carbon Nanoparticles (CNP),with a mean size of 150 nm,can be taken up selectively by lymphatics after injection into the tissue and draining regional lymph nodes are thereby colored black,which may provide surgeons the guidance to lymph node dissection and help them harvest lymph nodes after surgery,especially some small ones. but there was insufficient evidence to justify its efficacy for those purposes.Therefore,the investigators carried out a prospective randomized controlled trial on lymph node vital staining for lymph node dissection and harvesting in advanced gastric cancer to test this idea.

HIPEC-01 is a prospective, open, randomized multicenter phase III clinical study conducted in China. To determine the efficacy of hyperthermic intraperitoneal chemotherapy (HIPEC) in the treatment of locally advanced gastric cancer, patients are randomized into HIPEC group and control group. In HIPEC group, the patients undergo radical gastrectomy with D2 lymphadenectomy and HIPEC with paclitaxel and postoperative chemotherapy. Patients in the control group just undergo radical gastrectomy with D2 lymphadenectomy followed by postoperative chemotherapy. Patients in both groups receive 6-8 cycles of postoperative systemic chemotherapy (XELOX or SOX regimens) and are followed up for 5 years or until death.
