Filter by:gastric cancer is a highly aggressive malignancy with a poor overall outcome. The purpose of this study is to evaluate the 5-year survival of neoadjuvant S1, oxaliplatin, and docetaxel (SLOT) versus S1, oxaliplatin(SOX) in patients with locally advanced, resectable gastric/esophagogastric junction (EGJ) cancer.
This pilot clinical trial studies genetic analysis-guided irontecan hydrochloride dosing of modified fluorouracil, irinotecan hydrochloride, leucovorin calcium, oxaliplatin (mFOLFIRINOX) in treating patients with gastroesophageal or stomach cancer that has spread from where it started to nearby tissue or lymph nodes. Drugs used in chemotherapy, such as fluorouracil, irinotecan hydrochloride, leucovorin calcium, and oxaliplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Leucovorin calcium may also help fluorouracil work better. Genetic analysis may help doctors determine what dose of irinotecan hydrochloride patients can tolerate.
In oncological aspect, D1+ lymph node dissection would be enough for early stage gastric cancer in advanced gastric cancer (stage IB/IIA/IIB ).
Second-line chemotherapy represents an option in gastric cancer, especially for patients with adequate performance status. Two randomized phase III trials comparing 2nd-line docetaxel with best-supportive care have reported a benefit in favor of chemotherapy. Capecitabine is a fluoropyrimidine carbamate, which has a broader spectrum of antitumor activity than other fluoropyrimidines. In gastric cancer xenografts. metronomic capecitabine inhibited angiogenesis, growth of gastric cancer and improved survival with less toxicity. Given its potential low toxicity, the combination of docetaxel and metronomic capecitabine needs to be evaluated to assess efficacy and tolerability in patients with advanced gastric cancer previously treated with a fluoropyrimidine-based and platinum-based chemotherapy.
1. Target population:locally advanced gastric adenocarcinoma (LAGC, cT2~3/N+M0,or cT4aN+M0);no previous chemo or radio therapy. 2. Primary objective:Response rate of XELOX in the neoadjuvant setting of LAGC. Secondary objectives: - The progression free survival (PFS) in the perioperative treatment of locally advanced gastric adenocarcinoma (cT3/N+M0,or cT4aN+M0); - percentage of pathological response ; percentage of grade 3 or 4 adverse events as safety profile of perioperative treatments; - D2 resection -rate after neoadjuvant chemotherapy of XELOX; - Overall survival; - QOL during the whole period of treatment. 3. Trial design:This is a multicenter, single arm, open-label, phase II study to evaluate the efficacy and safety of Oxaliplatin plus capecitabine(XELOX) in the perioperative treatment of locally advanced gastric adenocarcinoma in combination with D2 resection. 4. Treatment plan:Patients will be given the perioperative chemotherapy as below once recruited:Schedule of Oxaliplatin plus capecitabine (XELOX) will be as follow: Capecitabine 1000 mg/m2 ,bid,d 1~14 every 3 weeks(treatment for 2 weeks and rest 1 week)Oxaliplatin:130mg/m2, iv infusion over 2h,d1,every 3 weeks. 5. Number of subjects:50 patients.Number of centers 5 sites, which have the high volume of gastric operations in China, more than 500 per year.
This is a randomized, multicenter, controlled trial to prove efficacy of S‐1 and Oxaliplatin as Neoadjuvant Chemotherapy for Advanced Gastric Cancer Patients who undergo D2 gastrectomy. The primary endpoint is three-year free disease and the second primary includes five-year overall survival, safety and R0 resection rate.
It is estimated to 7300 the number of new cases of gastric cancer each year in France. According to a randomized trial comparing 3 cycles of ECF (epirubicin, cisplatin, 5FU) administered before surgery and 3 cycles after surgery with surgery alone in adenocarcinoma of the stomach and lower esophagus, clinical and experimental data are the neoadjuvant chemotherapy is a new standard treatment for operable gastric cancer. This treatment with a median survival of more than 3 years to obtain a hazard ratio of 0.75 in favor of chemotherapy arm (p = 0.009). The 5-year survival being 36% for patients treated with chemotherapy versus 23% for surgery alone. Progression-free survival was also significantly prolonged with a hazard ratio of 0.66. The proposed clinical study by Ajani et al shows that the combination of Docetaxel with the schema Cisplatin - 5FU provides greater clinical benefit and induces to consider the triple combination as a reference treatment in metastatic gastric cancer in patients under 65 years. Preoperative radiochemotherapy is expected to increase the rate of curative resections, reduce gastrointestinal and hematologic toxicity. Two studies evaluating the feasibility of preoperative RTCT in operable gastric adenocarcinoma with continuous 5GU (+ or - paclitaxel) and 45 Gy are available and the combination 5FU oxaliplatin has been assessed in the esophagus and rectum tumors. The NESC study, Phase II, proposes the following schema: 2 cycles of chemotherapy with Docetaxel - Cisplatin - 5FU then preoperative chemoradiation with oxaliplatin - continuous 5FU and radiotherapy in locally advanced gastric adenocarcinoma stage III and IV non-metastatic administered before surgery.
This is an open-label, phase II study to evaluate the efficacy and safety of a modified regimen of oxaliplatin and S-1 on unresectable gastric adenocarcinoma in the first-line therapy.
Docetaxel was the first drug that showed survival benefits when added to the CF regimen, but it was very toxic. Docetaxel is also has a synergistic anti-cancer effect with S-1, in phase I/II studies. The use of a docetaxel plus S-1 combination as first-line chemotherapy for advanced gastric cancer achieved response rates of 46~56% and a median survival time of 14.0~14.3 months. Based upon this background, the aim of this study is to detect a significant increase in 3 year DFS of disease for the test group (DS) relative to the Control group (SP).
