The goal of this clinical research study is to learn if treatment with curcumin can help shrink or slow the growth of pancreatic cancers. The effect of curcumin on the way pancreatic cancer cells function and the safety of treatment with curcumin will also be studied.

Curcumin, a yellow substance extracted from the plant Curcuma longa, is commonly used as a food additive. It is a natural anti-inflammatory compound and has shown anti-tumor activity in the laboratory. During this study, you will receive much higher doses of curcumin than can be obtained from the diet.

During the study, you will receive curcumin by mouth every day. You will be required to take up to 16 pills per day each morning. Every 8-week period you take curcumin is considered a "course" of treatment. The number of courses you receive depends on how you are responding to treatment. You can continue treatment as long as the disease does not get worse. If the disease gets worse or you experience any intolerable side effects, you will be taken off the study and your doctor will discuss other treatment options with you.

You will be given a questionnaire to complete at the beginning of the study and once a week while you are on therapy to help the medical staff understand how the different symptoms from your disease are affecting you. This questionnaire, which should take about 5 minutes to complete, can be done over the telephone or with the help of one of the study staff during your visits.

At the end of each course of treatment (every 8 weeks), you will have a physical exam and the tumor will be re-evaluated using CT scans and/or blood (about 2 tablespoons) tests.

This is an investigational study. Curcumin is a commercially available substance, which is commonly used as a food additive. Up to 50 participants will take part in this study. All will be enrolled at M. D. Anderson.

2. The patient has a Karnofsky Performance Status of greater than or equal to 60 at study entry.
3. The patient has given informed consent.
4. The patient is at least 18 years of age.
5. The patient has adequate hematologic function as defined by an absolute neutrophil count greater than or equal to 1,500/mm3, platelet count greater than or equal to 100,000/mm3.
6. The patient has adequate hepatic function as defined by a total bilirubin less than or equal to 2.0 X ULN, alkaline phosphatase, AST and/or ALT less than or equal to 5 X ULN, and creatinine less than or equal to 2.0 mg/dL.
7. The patient has measurable disease.
8. The patient agrees to use effective contraception if procreative potential exists.

Exclusion Criteria:

1. The patient has a history of treated or active brain metastases, carcinomatous meningitis, an uncontrolled seizure disorder, or active neurological disease.
2. The patient has received prior radiation. Patients with measurable disease outside the radiation port or documented disease progression of previously irradiated measurable disease are eligible. Patient must be greater than or equal to four weeks post-therapy and have recovered from all toxicities.
3. The patient has an unstable medical condition according to the investigator, including uncontrolled diabetes mellitus or hypertension; active infections requiring systemic antibiotics, antivirals, or antifungals, unstable CHF, uncontrolled arrythmias, or unstable coagulation disorders.
4. The patient is pregnant (confirmed by serum Beta-HCG) or is breast feeding.
5. The patient has received an investigational agent(s) within four weeks of study entry.
