Brief Summary:

The goal of this clinical research study is to learn if gemcitabine given during surgery can enter pancreas cancer cells in patients who have already received chemotherapy and radiation.

Gemcitabine is a drug used to treat pancreatic cancer. However, it has not previously been studied if gemcitabine can enter pancreatic cancer cells. Gemcitabine is designed to block the growth of cancer cells, which may cause cancer cells to die.

Arm Intervention/treatment
Experimental: Gemcitabine Infusion
Gemcitabine administered intravenously as a dose of 500 mg/m2 at a fixed dose rate of 10 mg/m2/min for the first 5 patients (to validate hematologic safety). Next 15 subsequent patients receive 750 mg/m2 at a fixed dose rate of 10 mg/m2/min. The drug infusion started 50-75 minutes prior to complete gross tumor removal (timing dependent on dose) in order to have drug administration complete at tumor removal.
Drug: Gemcitabine
500 mg/m2 at a fixed dose rate of 10 mg/m2/min by vein for the first 5 patients during pancreatic surgery. Next 15 subsequent patients receive 750 mg/m2 by vein at a fixed dose rate of 10 mg/m2/min.
Other Names:
  • Gemcitabine Hydrochloride
  • Gemzar




Primary Outcome Measures :
  1. Intratumoral Gemcitabine Levels in Human Pancreatic Cancer Tissue After a Single Intraoperative Infusion [ Time Frame: 1 day ]
    Quantification of serum, PBMC, and cancer tissue levels of gemcitabine from frozen samples assessed using standardized techniques in high performance liquid chromatography-mass spectrometry. Blood vessels in resected tumors detected by immunohistochemistry (IHC) using antibodies to CD31 or vWF. The mRNA and protein expression of SHH, Gli and SMO measured by RT-PCR and IHC method. Range of levels in patients with PC established. These markers correlated to the gemcitabine levels measured in the cancerous tissue. The expression level of genes involved in gemcitabine metabolism in the resected primary tumors examined. The mRNA level measured using real time PCR and protein expression by IHC. Gene expression level correlated to the gemcitabine measurements. Markers of proliferation and apoptosis measured by p21 and Ki67 IHC and fluorescent TUNEL analysis.

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Cytologic or histologic proof of adenocarcinoma of the pancreas is required. Patients with Islet cell tumors are not eligible.
  2. Patients do not have known metastases.
  3. Patients must have potentially resectable or borderline resectable pancreatic cancer and have agreed to undergo surgical resection at MD Anderson Cancer Center if operable. They will have undergone staging (physical examination, chest x-ray, contrast enhanced CT or MRI (if CT contraindicated) and/or angiogram) to determine resectability.
  4. Patients have completed radiation and chemotherapy with either fluoropyrimidines (5-FU or capecitabine) or gemcitabine as a radiosensitizing agent as part of their preoperative therapy. Previous systemic chemotherapy alone is not allowed. Preoperative therapy will be completed at least 4 weeks prior to surgery.
  5. Patients with Karnofsky performance status > 70 are eligible.
  6. There will be no upper age restriction. Patients less than 18 years of age are excluded from the protocol because adenocarcinoma of the pancreas is rarely seen in the pediatric population.
  7. Adequate renal and bone marrow function: Leukocytes >= 3,000/uL; Absolute neutrophil count >= 1,500/uL; Platelets >= 100,000/Ul; Serum creatinine <= 2.0 mg/dL; Creatinine clearance >= 60 ml/min (calculated by the Cockcroft -Gault equation)
  8. Adequate Hepatic function (endoscopic or percutaneous drainage as needed): Total bilirubin < = 3 X institutional upper limits of normal (ULN); AST (SGOT)/ALT (SGPT) <= 5 X institutional ULN
  9. Patients must have no fever or evidence of infection or other coexisting medical condition that would preclude administration of gemcitabine. Patients with uncontrolled congestive heart failure, unstable angina and myocardial infarction within 3 months will be excluded.
  10. Patient is not pregnant. Women of childbearing potential (i.e., women who are pre-menopausal or not surgically sterile) must use acceptable contraceptive methods (abstinence, intrauterine device [IUD], oral contraceptive or double barrier device) and refrain from breast-feeding, as specified in the informed consent.
  11. Patients must sign a study-specific consent form.

Exclusion Criteria:

  1. Major cardiovascular or pulmonary comorbidity that precludes use of general anesthesia (NYHA [New York Heart Association] Class III and IV).
  2. Identification of metastatic disease.
  3. Patients with a known hypersensitivity to Gemcitabine.
  4. Pregnant women
  5. Inability to comply with study and/or follow-up procedures.
  6. Patients < 18 years of age.
