RATIONALE: Drugs used in chemotherapy, such as fluorouracil, oxaliplatin, and leucovorin, 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.
PURPOSE: This phase II trial is studying how well giving fluorouracil together with oxaliplatin and leucovorin works in treating patients with metastatic stomach cancer or gastroesophageal junction cancer.
|Condition or disease||Intervention/treatment||Phase|
|Gastric Cancer||Drug: fluorouracil Drug: leucovorin calcium Drug: oxaliplatin Genetic: gene expression analysis Genetic: polymorphism analysis Genetic: protein expression analysis Other: pharmacological study||Phase 2|
- Compare the response rate in patients with "good risk" genotype (TSER*2/*2 or TSER*2/*3 genotype [low TS expression]) to historical control response rates in non-genotype selected patients.
OUTLINE: This is a multicenter study.
Patients receive oxaliplatin IV over 2 hours, leucovorin calcium IV over 2 hours, and fluorouracil IV over 5 minutes and then continuously over 46 hours on days 1 and 15. Courses repeat every 2 weeks in the absence of unacceptable toxicity or disease progression.
Available tumor tissue samples are assessed for expression of TS at the mRNA and protein levels. The results are correlated with germline and tumor TSER genotypes as well as response to the study treatment regimen. Polymorphisms in other genes associated with treatment outcome or toxicity are also assessed.
After completion of study treatment, patients are followed periodically for 4 years.

- Number of Patients With Each Response in "Good Risk" Genotype (Thymidylate Synthase Promoter Enhancer Region [TSER]*2/*2 or TSER*2/*3 Genotype [Low TS Expression]) [ Time Frame: every 8 weeks to progression ]Per RECIST criteria v. 1.0: measurable lesions: complete response (CR) disappearance of target lesions, partial response (PR) > 30% decrease in the sum of the longest diameter (LD) of target lesions, progressive disease (PD) > 20% increase in the sum of the LD of target lesions or appearance of new lesions, stable disease (SD) neither sufficient decrease nor increase of the sum of smallest sum of the LD of target lesions. This is a one-time assessment.
