CA 19-9 levels are assessed in weeks 1 and 3 of each course. Patients who are biomarker responders continue to receive treatment with gemcitabine hydrochloride alone. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients who are no longer biomarker responders or show other evidence of disease progression proceed to therapy comprised of gemcitabine hydrochloride and S1.\n* Gemcitabine hydrochloride and S-1 treatment: Patients receive gemcitabine hydrochloride IV over 100 minutes on days 1 and 15 and oral S-1 twice daily on days 1-7 and 15-21. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.\n\nPatients undergo core needle tumor biopsy and fine-needle aspiration at baseline.

Tissue samples are also analyzed by microarray and comparative genomic hybridization to identify new genes that may predict chemotherapeutic response or mediate sensitivity to anticancer therapy. Mutational status of KRAS and p53 gene are also assessed.\n\nBlood samples are collected at baseline and are analyzed by genotyping assays to identify polymorphic variants of select genes.\n\nAfter completion of study treatment, patients are followed monthly.\n\nPROJECTED ACCRUAL: A total of 100 patients will be accrued for this study.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion criteria\n\n* Adenocarcinoma of the pancreas that is already or will be histologically or cytologically proven.\n* Patients must have either locally advanced (unresectable) or metastatic disease.\n* Radiographically measurable disease is not required.\n* No prior therapy for advanced pancreatic cancer.
