Study Summary

RATIONALE: Studying samples of tumor tissue and blood from patients with cancer in the laboratory may help doctors learn more about changes that may occur in DNA and identify biomarkers related to cancer. It may also help doctors predict a patient's response to treatment and help plan the best treatment. PURPOSE: This phase II trial is studying gene expression in predicting treatment response in patients receiving gemcitabine and S-1 for locally advanced unresectable or metastatic pancreatic cancer.

Primary Outcome

Pearson's correlation coefficients ("r") will be calculated to summarize the relationship between RRM1 and response to gemcitabine. Coefficients are on a continuous scale ranging from -1 to +1 with a value of -1 indicating a perfect negative linear association of RRM1 and response to gemcitabine, a value of 0 indicating no association between RRM1 and response to gemcitabine, and a value of +1 indicating a positive linear association of RRM1 and response to gemcitabine.

Interventions

  • DRUG S-1
  • DRUG gemcitabine hydrochloride
