Phase I Study of Margin-Intense Combination Therapy for Patients With Potentially Resectable Pancreatic Adenocarcinoma

RATIONALE: Stereotactic body radiation therapy may be able to send x-rays directly to the
tumor and cause less damage to normal tissue. Drugs used in chemotherapy, such as gemcitabine
hydrochloride, work in different ways to stop the growth of tumor cells, either by killing
the cells or by stopping them from dividing. Giving stereotactic body radiation therapy
together with gemcitabine hydrochloride may kill more tumor cells.

PURPOSE: This phase I trial is studying the side effects of stereotactic body radiation
therapy when given with or without gemcitabine hydrochloride in treating patients with
pancreatic cancer that can be removed by surgery.

OBJECTIVES:

- To demonstrate the feasibility and safety of administering margin-intensive stereotactic
body radiotherapy together with preoperative gemcitabine hydrochloride to patients with
resectable pancreatic adenocarcinoma.

OUTLINE: This is a multicenter, dose-escalation study of gemcitabine hydrochloride. Patients
receive 1 of 2 treatment regimens.

- Regimen 1: Patients undergo a single fraction of margin-intensive stereotactic body
radiotherapy (SBRT) on day 1. Patients undergo pancreatoduodenectomy between days 15-43.

- Regimen 2: Patients receive gemcitabine hydrochloride IV over 30 minutes on days 1, 8,
and 15. Patients undergo a single fraction of SBRT between days 21-28 followed by
pancreatoduodenectomy between days 35-63.

After completion of study treatment, patients are followed periodically for 5 years.

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

- Negative pregnancy test

- 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

- No clinically significant cardiac disease, including the following:

- Uncontrolled hypertension, defined as blood pressure > 160/90 mm Hg on medication

- Myocardial infarction within the past 6 months

- NYHA class II-IV congestive heart failure

- Unstable symptomatic arrhythmia requiring medication (e.g., chronic atrial
arrhythmia [atrial fibrillation or paroxysmal supraventricular tachycardia])

- Atrial arrhythmia allowed provided it is well-controlled on stable
medication

- No current or recent (within the past 6 months) unstable angina

- No recent (within the past 6 months) arterial thromboembolic events, including
transient ischemic attack, cerebrovascular accident, or clinically significant
peripheral artery disease

- No evidence of bleeding diathesis or coagulopathy

- No significant traumatic injury within the past 28 days

- No serious nonhealing wound, ulcer, or currently healing fracture

- No AIDS

- No significant infection or other coexisting medical condition that would preclude
study therapy

- No gastrointestinal fistula or perforation within the past 10 years

PRIOR CONCURRENT THERAPY:

- More than 2 years since prior chemotherapy (other than for pancreaticobiliary cancer)

- More than 28 days since prior major surgical procedure or open biopsy

- No prior intraabdominal radiotherapy in the planned field of pancreatic
margin-intensive radiotherapy

- No prior organ transplantation

- No concurrent major surgical procedure

- No other concurrent cytotoxic chemotherapy or anti-neoplastic biologic agents
