简要总结
RATIONALE: Drugs used in chemotherapy, such as oxaliplatin and capecitabine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more tumor cells. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving chemotherapy together with radiation therapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed.
PURPOSE: This phase II trial is studying how well giving oxaliplatin and capecitabine together with radiation therapy works in treating patients with stomach cancer that can be removed by surgery.
详细描述
OBJECTIVES:
- Determine the pathologic complete response rate in patients with primary gastric adenocarcinoma treated with neoadjuvant chemoradiotherapy comprising oxaliplatin, capecitabine, and radiotherapy. (This will not be completed as this study was closed early due to poor accrual.)
- Assess the frequency and severity of toxicities associated with this regimen.
- Explore, preliminarily, the association between DNA repair genes (ERCC-1, XRCC1, GST-P1, XPD, XPA, ribonucleotide reductase), target enzymes (thymidylate synthase [TS], dihydropyrimidine dehydrogenase, thymidine phosphorylase [TP]), and angiogenic factors (vascular endothelial growth factor [VEGF], epidermal growth factor [EGF], PD-ECGF, basic fibroblast growth factor, TSP-1 and -2, transforming growth factor [TGF]-β, and IL-8) and response to neoadjuvant therapy in patients with adenocarcinoma of the stomach. (This will not be completed as this study was closed early due to poor accrual.)
- Explore, preliminarily, the association of haplotypes of candidate genes of TS, TP, ERCC-1, XPD, GST-P1, cyclooxygenase-2, EGF receptor, TGF-β, VEGF, and IL-8 with response and toxicity to neoadjuvant chemoradiation therapy in these patients. (This will not be completed as this study was closed early due to poor accrual.)
- Explore, preliminarily, the feasibility of performing comparative genomic hybridization for analysis of DNA copy number changes in predicting response to neoadjuvant chemoradiation therapy. (This will not be completed as this study was closed early due to poor accrual.)
OUTLINE: This is a multicenter, pilot study.
- Neoadjuvant chemotherapy: Patients receive oxaliplatin IV over 2 hours on days 1 and 22 and oral capecitabine twice daily on days 1-14 and 22-35 in the absence of disease progression or unacceptable toxicity.
- Neoadjuvant chemoradiotherapy: Patients receive oral capecitabine twice daily on days 43-77 and undergo radiotherapy once daily on days 43-47, 50-54, 57-61, 64-68, and 71-75 in the absence of disease progression or unacceptable toxicity.
- Surgery: Patients with stable or responding disease undergo surgery 4-6 weeks after completion of chemoradiotherapy.
Tumor tissue is obtained at surgery or endoscopic biopsy. Gene expression analysis and comparative genomic hybridization testing are conducted on the tissue. Blood is drawn prior to beginning study treatment and is analyzed for germline polymorphisms.

结局指标
主要结局
Pathologic Complete Response
时间窗: 17-19 weeks
Pathologic complete response rates (pCR) of primary gastric adenocarcinoma when treated with oxaliplatin and capecitabine followed by capecitabine and radiation pre-operatively. On review of the resected gastric specimen and accompanying lymph nodes, pCR is no cancer recognized by the pathologist. Margins are free of tumor.
次要结局
- Number of Patients With Grade 3 Through 5 Adverse Events That Are Related to Study Drug(Patients were assessed for adverse events after pre-operative chemotherapy, after pre-operative chemoradiation and within 14 days of surgery.)
