Brief Summary
The purpose of this study is to assess how effective celecoxib is in limiting production of a hormone, prostaglandin, in the subject's body. It is felt that this hormone is involved in the evolution of pre-cancerous growths in the colon to cancerous stage or in the progression of an existing cancer. To answer this question, some subjects are given the new investigational drug, and other subjects a placebo. A placebo is a capsule that contains inactive ingredients. Only by comparing the response of two subject groups, one receiving placebo (inactive), and one receiving celecoxib (active), will we be able to know whether or not celecoxib actually works. The outcome we are assessing is the hormone activity before and after celecoxib is given.

Outcome Measures
Primary Outcomes (2)
Number of Subjects Witha Change (IMPROVEMENT) in Colo-rectal Adenocarcinoma as Measured by Cyclooxygenase-2 Activity After 7 Days of Celecoxib
The Colo-Rectal adenocarcinoma will be measured by cyclooxygenase-2(COX-2) activity at 7 days post baseline. Cox-2 activity is measured by assessing tumors and normal tissue using "Electron microscope and Tandem mass Spectrometry" methodology though the UAB shared Mass Spectrometry facility. Improvement was measured by 2-fold increase in COX-2 activity from baseline. The methodology used was High Performance Liquid Chromatography(HPLC). additional studies include expression of genes thought to be important in colorectal carcinogenesis: COX-1 and 2, MMP, 2 7, and 9, tissue inhibitor of metalloproteinases(TIMPs) 1 ans 2 and beta-catenin.
baseline to 7 days
Subjects With Positive Response 72 Hours After Administration of Study Treatment as Measured by Immunoblot
At 72 hours after start of treatment, the number of subjects with immunoblot demonstrated a 1.5 to 2 fold increase in 15-LOX-1 protein expression in human colorectal adenocarcinoma cell line with epithelial morphology(HT-29) and dihydrolipoamide dehydrogenase(DLD)-1 cells.
baseline to 72 hours
Study Arms (2)
study drug BID for 7 days before surgery
ACTIVE COMPARATOR400 mg Celecoxib the study drug will be given for 7 days before surgery
Placebo for 7 days before surgery
PLACEBO COMPARATORPlacebo in a one to one randomization prior to surgery
Interventions
Eligibility Criteria
You may qualify if:
- Mass suspicious for carcinoma, clinical diagnosis of adenocarcinoma of the colon (to be histologically confirmed upon study entry) or an adenoma that is not removable by endoscopy.
- Patient must be undergoing colo-rectal resection
- age \> 18yrs
- Karnofsky performance status(KPS) \> 60.
- Signed and dated informed consent.
- Complete history and physical examination within 30 days of study entry.
- Laboratory evaluations within 30 days of study entry to include: Complete Blood Count(CBC) with differential and platelets, Blood Urea Nitrogen(BUN), creatinine, bilirubin, serum glutamic-oxaloacetic transaminase (SGOT), serum glutamic-pyruvic transaminase(SGPT), lactate dehydrogenase(LDH), alkaline phosphatase, total protein, albumin and carcinoembryonic antigen(CEA).
- Chest x-ray within 30 days of study entry.
- The subject has no other serious medical illness, other than that treated by this study, which would limit the ability of the patient to receive protocol therapy, or psychiatric condition which would prevent informed consent.
You may not qualify if:
- severe infection ;White Blood Cell Count(WBC) \> 2 times normal, fever, sepsis)
- immunosuppression (steroids, transplant patient)
- emergent operation(perforation, obstruction).
- Patients with serum bilirubin or creatinine levels greater than two times the normal upper limit would be excluded.
- Pregnant or lactating women or subjects of child bearing age who do not practice effective means of birth control
- Sulfonamide allergy
- Recurrent or previous history of known ischemic heart disease or thrombotic events as well as any angioplasty or cardiac by-pass procedures in the previous 12 months.
- Medications taken by the patient that are listed in section 9.0 of this protocol would be reviewed by the enlisting physician prior to entry into the study. Warfarin, aspirin and methotrexate would be stopped prior to protocol entry as these are stopped prior to any surgery. The most common of the listed medications would be ACE inhibitors and furosemide. The dose, schedule and indications of the medications would be reviewed with the patient and a decision regarding entry into the study would be made by the enlisting physician. Other less common medications will be similarly reviewed, however most had little or no clinical side effects despite potential biochemical interactions.
- Medications known to be COX inhibitors would have to be stopped prior to entry into the study. This would include any aspirin,nonsteroidal antiinflammatory drugs(NSAID) (ibuprofen, naproxen, rofecoxib, celecoxib, Mobic, etc) or over the counter cold medication that might contain these substances. A list of common over-the-counter medications that might contain such substances will be reviewed with the patient and if there are any questions after the study has begun, instructions to call before taking any medications will be given.

Limitations and Caveats
The most prominent factor that limited enrollment was this period of time was at the point that the FDA released its finding about the possible cardiac risks associated with Rofecoxib (VIOXX).
