Filter by:This study is an open-label, single center, and a single arm phase II study to evaluate the clinical response and safety of perioperative S-1 plus docetaxel. Perioperative chemotherapy is composed of 3 cycles of preoperative S-1/docetaxel and 3 cycles of postoperative S-1/docetaxel.Chemotherapy regimen: - S-1 80 mg/m2/day every 12-h p.o. on days 1(evening)-15 (morning) - Docetaxel 35 mg/m2 mixed in d5w 250 ml iv over 60-min on days 1 and 8
This study is an open-label, single-center, and randomized phase II study designed to evaluate each efficacy and safety of S-1 and capecitabine in the elderly and/or poor performance status patients with recurrent or metastatic gastric cancer. The randomization will be stratified by age (70-85 years versus 65 years and < 70 years) and performance status, which is dependent on age group; in 70-85 years, ECOG performance status 0-1 versus 2 and in ³65 years and <70 years, ECOG performance status 2 versus 3. - S-1 40mg/m2 orally twice daily on days 1 (evening) - 15 (morning) - Capecitabine 1250mg/m2 orally twice daily on days 1 (evening) - 15 (morning) Treatment will be administered every 3 weeks and will be continued in the absence of disease progression or unacceptable toxicity.
Randomized phase II study designed to evaluate the efficacy and safety of continuous S-1 plus oxaliplatin versus intermittent S-1 plus oxaliplatin as first-line therapy in patients with recurrent and/or metastastic gastric carcinoma. Within 2 weeks of the end of induction chemotherapy of 6 cycles with S-1 plus oxalipatin, patients who don't experience progression will be randomized to the continuous S-1 plus oxaliplatin arm or the intermittent S-1 plus oxaliplatin arm in a 1:1 ratio.
To evaluate the efficacy and safety of weekly administered combination of docetaxel/cisplatin and docetaxel/oxaliplatin in chemotherapy-naïve patients with advanced gastric cancer. The primary endpoint will be the response rate.
Patients with recurrent or metastatic gastric cancer can benefit from palliative chemotherapy. However, over half of patients with metastatic gastric cancer who received chemotherapy failed to achieve response and even in these responders, the duration of responses was as short as a few months. Patients with metastatic gastric cancer who fail to respond or have relapse after first line chemotherapy have a grim prognosis and a standard salvage treatment is not available. We designed this phase II trial to determine the efficacy and safety of irinotecan monotherapy or combination (ILF) as second-line therapy for advanced gastric cancer.
OBJECTIVES: - Determine response and survival of patients with peritoneal carcinomatosis treated with cytoreductive surgery plus intraoperative peritoneal hyperthermic chemotherapy with cisplatin and mitomycin - Assess the quality of life of patients treated with this regimen. OUTLINE: Patients are randomized into IPHC group and control group. In the former group, the patients undergo cytoreductive surgery plus intraoperative hyperthermic peritoneal perfusion with cisplatin and mitomycin over 60 minutes. Patients in the control group just underwent routine cytoreductive surgery. All patients in both groups receive the standard conventional chemotherapy after surgery. Quality of life is assessed at study initiation, at 1, 3, 6 months. Patients are followed at 4 weeks, every 3 months for 1 year, and then every 6 months for up to 3 years.
The purpose of this study is to assess the usefulness of laparoscopic surgery for gastric cancer in comparison with open gastrectomy.
Rationale: Adjuvant chemoradiation considered as standard of care after curative surgery for adenocarcinoma of stomach and gastroesophageal cancer. Preoperative chemotherapy in the in locally advanced gastric cancer results in significant tumoral downstaging with improved rate of curative resections. Purpose: To evaluate feasibility and safety of combination of preoperative chemotherapy and postoperative chemoradiation for locally advanced adenocarcinoma of stomach and gastroesophageal cancer
The primary end point of the study is confirmed objective response rate (complete response [CR] and partial response [PR]). A response rate of 80 percent for cetuximab plus cisplatin and weekly 24-hour infusion of high-dose 5-fluorouracil and leucovorin (P-HDFL) chemotherapy is assumed. The Simon two-stage design will be used for P1 - P0 = 0.20. The response rates of interest are P0 = 60% and P1 = 80%. The investigators will reject cetuximab plus P-HDFL chemotherapy if the response rate is 8/13 at the first stage, and will reject the cetuximab plus P-HDFL chemotherapy if the response rate is 25/35 at the second stage. If there are more than 8 responses in 13 patients in the first stage, the study will continue to a total of 35 patients in the second stage. If there are more than 25 responses in 35 patients in the second stage, this treatment will be acceptable with a p-value of 0.05 and of 0.20. Evaluable patients for response will be those who received at least 4 doses of cetuximab (i.e. one cycle of protocol treatment). All enrolled patients will be subjected to toxicity evaluations. The primary end point of the study is confirmed objective response rates (by RECIST, Response Evaluation Criteria in Solid Tumors). The secondary end points of the study are progression-free survival, overall survival, and treatment-related toxicities. The analysis of response to treatment will be restricted to the eligible patients with at least one measurable lesion. The safety analysis will be restricted to the patients who received at least one cycle of the administered chemotherapy. The time-to-event end points will be estimated using the method of Kaplan and Meier and based on the intent-to-treat principle. Overall survival will be defined as the time interval between the date of study entry and the date of death. Progression-free survival will be defined as the time interval between the date of study entry and the date of disease progression or death, whichever occurred first. Duration of response will be defined as the time interval between the date of initial objective response and the date of disease progression, which is only for responders. If the event is not yet observed at the time of the last record, the patient will be censored at that time point.
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.
