Filter by:This phase II trial will compare the efficacy and toxicity of the combination of Irinotecan and Oxaliplatin versus 5-FU/LV and Oxaliplatin as first line treatment in patients with locally advanced or metastatic gastric cancer
The purpose of this study is to evaluate the progression free survival of capecitabine (Xeloda), oxaliplatin and bevacizumab (Avastin) in previously untreated metastatic esophagogastric adenocarcinomas.
Considering synergism between docetaxel (D), capecitabine (X), and oxaliplatin (O) and favourable toxicity profile of oxaliplatin over cisplatin, it is to be expected that combination of docetaxel, capecitabine, and oxaliplatin (DXO) will be more effective than other regimens and feasible in advanced gastric cancer. DXO regimen can be also easily administered on out-patient setting. However, so far, DXO combination has not been tried in advanced gastric cancer. The investigators will determine maximum tolerated dose of DXO regimen in this phase I study.
Cetuximab, Paclitaxel, Carboplatin and Radiation for Esophageal, Gastroesophageal Junction and Gastric Cancer
This single arm study will assess the efficacy and safety of Xeloda in combination with oxaliplatin as first-line chemotherapy in patients with advanced and/or metastatic gastric cancer who have had no prior chemotherapy for advanced or metastatic disease. Eligible patients will receive Xeloda 1000mg/m2 po twice daily, D1-D10 every 2 weeks (10 days treatment followed by 4 days rest period) plus oxaliplatin 85 mg/m2/day iv, D1 every 2 weeks. The anticipated time on study treatment is until disease progression, and the target sample size is <100 individuals.
RATIONALE: Chemotherapy may cause blood clots to form in the thigh, leg, and lung. This study may help doctors understand how often blood clots occur in patients undergoing chemotherapy. PURPOSE: This clinical trial is studying how often blood clots occur in patients undergoing chemotherapy for solid tumors, including colorectal cancer, stomach cancer, lung cancer, ovarian cancer, pancreatic cancer, prostate cancer, or metastatic breast cancer
Study H3E-MW- S108 is a multicenter, single arm, open-label Phase 2 study to determine the response rate of pemetrexed plus cisplatin in patients with Stage IV gastric cancer, not amenable to curative surgery, or recurrence after prior surgery, who have had no prior chemotherapy. It was planned to enroll approximately 50 patients who qualified for tumor response population.
Thymidylate Synthase (TS) is a key enzyme in the synthesis of DNA and the target enzyme inhibited by 5-fluorouracil (5-FU). TS level in the tumour cells has been reported as predictive to response to 5-FU and a prognostic factor in colorectal and gastric cancer patients. We plan to study TS by immunohistochemistry (IHC) in the paraffin blocks of tumour tissue. A combined comparative genomic hybridization (CGH) and expression microarray analysis of gastric cancer specimens before and after neoadjuvant chemotherapy. CGH will be performed using standard technique routinely done in Dr Patrick Tan's laboratory at the National Cancer Centre, which determines the gain or loss of DNA copies of each chromosome. Total RNA will be extracted from at least one biopsy sample which contains at least 50% cancer cells by homogenization of the tumour tissue and tri-sol method. 5 ug of RNA were amplified and hybridized with the C-DNA microarrays of 18K targets. Primary Objective 1. Feasibility and safety of pre-operative chemotherapy in locally advanced gastric cancer. Secondary Objective 1. Complete clinical and pathological response rates to pre-operative chemotherapy in locally advanced gastric cancer 2. Complete resection rate. 3. Time to recurrence, disease free and overall survival 4. Correlation of clinical outcome with (Runt-related transcription factor) RUNX-3 methylation status and Thymidylate synthetase in the tumor tissue. 5. Correlation of CGH and gene expression profile and their changes after chemotherapy with clinical outcome. Patients may be included in the study only if they meet all of the following criteria: Age at least 18 years. Histologic or cytologic diagnosis of adenocarcinoma of stomach or gastric cardia (Siewert Classification Type III) Preoperative Stage T3-4NxM0 by endoscopic ultrasound, CT of the abdomen/pelvis and laparoscopy. (CT of the chest if it is a cardia lesion). Absence of malignant cells in peritoneal lavage fluid during laparoscopic examination. Patients must not have received any prior chemotherapy or hormonal therapy for the treatment of gastric cancer. Karnofsky performance status of 70 or higher. Estimated life expectancy of at least 12 weeks. Adequate organ function including the following: - Bone marrow: White blood cells (WBC) at least 3.5 x 109/L Absolute neutrophil (segmented and bands) count (ANC) at least 1.5 x 109/L Platelets at least 100 x 109/L Haemoglobin at least 9g/dL - Hepatic: Bilirubin within upper limit of normal (ULN), Aspartate transaminase (ALT) or Alanine transaminase (AST) not more than 2.5x ULN Alkaline phosphatase not more than 2.5x ULN. - Renal: creatinine not more than 1.5x ULN Signed informed consent by patient or legal representative. Patients with reproductive potential must use an approved contraceptive method if appropriate (eg, intrauterine device, birth control pills, or barrier device) during and for three months after the study. Females with childbearing potential must have a negative serum pregnancy test within 7 days prior to study enrollment. The study plans to recruit 30 patients in 12-18 months.
Primary: - To demonstrate that capecitabine/oxaliplatin as adjuvant chemotherapy is superior to observation alone in terms of 3 year disease-free survival (DFS) rate in chemotherapy-naïve patients who underwent potentially curative resection for gastric cancer. Secondary: - To compare the overall survival of surgery and capecitabine/ oxaliplatin as adjuvant therapy versus surgery alone. To evaluate the safety profile of capecitabine/oxaliplatin adjuvant therapy.
This is an open-label, international, two-arm, parallel, randomized, Phase 3 study evaluating the efficacy and safety of S-1/cisplatin versus 5-FU/cisplatin in patients with advanced gastric cancer previously untreated with chemotherapy for advanced disease. Patients will be randomly assigned (1:1) to S-1/cisplatin (experimental arm) or 5-FU/cisplatin (control arm). Patients will be stratified by number of metastatic sites (one vs. more than one), locally advanced or metastatic disease, prior adjuvant therapy (yes or no), measurable or non-measurable disease, and center.
