You may be eligible if

• DISEASE CHARACTERISTICS:
• Pathologically confirmed localized adenocarcinoma of the pancreas or distal common bile duct
• * Pancreatic ductal adenocarcinoma or peripancreatic cholangiocarcinoma
• Resectable disease, as determined by the Gastrointestinal Cancer Working Group disease-oriented team
• * Criteria used to define unresectability will include, but not be limited to, the following:
• * Tumor encases \> 180 degrees of the circumference of the superior mesenteric artery
• * Tumor encases the common hepatic artery with no anatomic option for reconstruction following segmental resection
• * Superior mesenteric vein occluded or encased with no option for reconstruction following segmental resection
• * Soft tissue infiltration of the retroperitoneum to the left of the superior mesenteric artery
• All malignant disease must be encompassed within a single radiotherapy field
• No metastatic disease
• PATIENT CHARACTERISTICS:
• Zubrod performance status 0-1
• Absolute granulocyte count \> 1,500/mm³
• Platelet count \> 100,000/mm³
• Creatinine clearance \> 50mL/min
• AST and ALT \< 5 times upper limit of normal
• Serum bilirubin \< 5 mg/dL (with biliary decompression)
• INR ≤ 1.5
• Not pregnant or nursing

• Fertile patients must use effective contraception
• Medically fit for pancreatic surgical resection, as determined by the investigating surgeons at the time of study enrollment
• No evidence of an active second invasive malignancy outside the area of the pancreas or biliary system within the past 2 years, except for non-melanomatous skin cancer or carcinoma in situ of the breast, bladder, cervix, or uterus
