Active clinical trials for "Stomach Neoplasms"

To compare left thoraco-abdominal approach with abdominal and transhiatal approach to cardia or subcardia cancer

The goal of this study is to compare the tumor response in gastric cancer patients given neoadjuvant chemotherapy with the corresponding result obtained from zebrafish patient-derived tumor xenograft(PDX) model given the same regimen. The main question it aims to answer is whether this PDX model of zebrafish could accurately predict the effect of chemotherapy in advanced gastric cancer. Participants will be given the standard neoadjuvant treatment administrated by their own doctors and tumor response will be observed and recorded. Meanwhile, tumor samples derived from patients before chemotherapy will be transplanted to zebrafish and the same regimen will be given to the PDX models correspondingly. The tumor response data both from clinical practice and PDX model platform will be analysed and compared to evaluate the power of this zebrafish model platform in drug efficiency prediction.

This study is a single arm, single center phase II study of AZD5363 in combination with paclitaxel in patients with advanced gastric adenocarcinoma harboring PIK3CA mutation or amplification as a second line chemotherapy. Patients will receive AZD 5363 plus weekly paclitaxel combination regimen. A arm is composed of 25 patients. Tumour evaluation using RECIST 1.1 will be conducted at screening (within 28 days prior to first dose) and every 8 weeks relative to the date of enrollment, up to week 40, then every 16 weeks until objective disease progression (within a window of +/- 7 days of the scheduled date). Study treatment will be continued until objective disease progression.

For the gastric cancer, paclitaxel is recommended as salvage standard treatment. Afatinib is a novel, potent, small ErbB family blocker that covalently binds and irreversibly blocks signaling through activated EGFR, HER2 and ErbB4 receptors, as well as the transphosphorylation of ErbB3. The investigators suggest a randomized phase II trial of afatinib plus weekly taxol(paclitaxel) for previously treated EGFR positive gastric cancer patients. The aim of current trial is to evaluate the antitumor efficacy of afatinib for target enriched patients in gastric cancer.

The purpose of our study is to assess the efficacy and safety of apatinib in elderly advanced gastric cancer patients, and to find the relationship between the expression of VEGFR-2 and efficacy of apatinib treatment.

Patients diagnosis with inoperable gastric cancers are treated with palliative chemotherapy. Palliative chemotherapy had proven to be better overall survivals and quality of life in unresectable advanced gastric cancer. NCCN guideline suggested two or three drug cytotoxic regimen as a first line therapy. But response rate of those regimens is about 50 percent. Disappointingly most of cases are about to experience progression of disease. Second line regimens of palliative chemotherapy are also have shown its efficacy and recommended within patients with better performance status. But There is still lack of evidences in gastric cancer patients second line chemotherapy. Several phase II trial those subjects are 2nd line palliative chemotherapy in gastric cancer had suggested that irinotecan, taxane, oxaliplatin, oral fluorouracil.Investigator assessed whether cisplatin in combination with paclitaxel would increase response rate in patient previously treated for advanced gastric cancer compared with FOFIRI regimen.

This study will conduct a phase II study of triple combination with oxaliplatin, irinotecan, and S-1 as the first-line chemotherapy in patients with advanced gastric cancer.

The purpose of this study is to assess the relationship of pCR rate and efficacy by comparing the two drugs and three drugs as neoadjuvant chemotherapy in advanced gastric cancer patients.

This study will evaluate the efficacy and safety of oral capecitabine (Xeloda) versus 5-fluorouracil (5-FU), in combination with intravenous (IV) cisplatin, in participants with advanced and/or metastatic gastric cancer. The anticipated time on study treatment is at least 6 weeks and continued up to disease progression, and the target sample size is 300 individuals.

The purpose of this study is to explore the safety, feasibility, long-term and oncologicaloutcomes of laparoscopic-assisted gastrectomy for advanced Gastric Cancer after neoadjuvant chemotherapy.
