Rosuvastatin in Treating Patients With Stage I or Stage II Colon Cancer That Was Removed By Surgery

Inclusion Criteria * Patients must have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1. * Patients must have the ability to swallow oral medication. * Patients must have resected adenocarcinoma of the colon staged as American Joint Committee on Cancer (AJCC) Stage 0, I, II, or III. * Patients must have had surgical resection of the colon adenocarcinoma with curative intent within 1 year prior to randomization. (Laparoscopically-assisted colectomy is permitted.) * Patients must have completed any adjuvant therapy prior to randomization. * Patients who are taking cardioprotective low-dose aspirin at study entry must not have clinically significant toxicity, as determined by the investigator, that precludes continuation of aspirin, and the patient must be willing to continue aspirin therapy (81 mg or 325 mg) throughout study therapy. * Colonoscopy requirements within 180 days prior to randomization: * The patient must have either undergone a preoperative or postoperative documented colonoscopy to the cecum (or small bowel anastomosis) with adequate bowel preparation. * All observed polyps must have been removed. (Polyps can be removed during colonoscopy or surgery performed prior to randomization.) * Postoperative serum creatinine performed within 90 days prior to randomization must be less than or equal to 1.5 x upper limit of normal (ULN) for the lab. * The following criteria for evidence of adequate hepatic function based on postoperative testing performed within 90 days prior to randomization must be met: aspartate aminotransferase (AST) or alanine aminotransferase (ALT) less than or equal to 3.0 x ULN for the lab, and Total bilirubin less than or equal to 1.5 x ULN for the lab Exclusion Criteria * Tumor with the distal border located less than 12 cm from the anal verge. * Total colectomy or total proctocolectomy. * Classic Familial Adenomatous Polyposis, Attenuated Familial Adenomatous Polyposis (i.e., 20 or more adenomas, either synchronous or metachronous), or Hereditary Nonpolyposis Colorectal Cancer (Lynch Syndrome). * Malabsorption syndrome, ulcerative colitis, inflammatory bowel disease, resection of the stomach or small bowel, or other disease significantly affecting gastrointestinal function. * History of documented upper GI bleeding or upper GI ulcerative disease. * Statin use within 30 days prior to randomization. * Hyperlipidemia with clinical indication for statin therapy or other prescribed medication. Determination of acceptable fasting lipid values, within 90 days prior to randomization, should be in accordance with current dyslipidemia management guidelines. * Unwillingness to discontinue chronic use of nonsteroidal antiinflammatory drugs (NSAIDs) (other than cardioprotective low-dose aspirin 81 mg or 325 mg) prior to randomization. * Anticipated need for chronic use of NSAIDs (other than cardioprotective low-dose aspirin 81 mg or 325 mg). * Inadequately treated hypothyroidism, as determined by the investigator. * History of myopathy or rhabdomyolysis. * Hypersensitivity or intolerance to statins. * Chronic drug therapy with cyclosporine, coumarin anticoagulants, gemfibrozil, some other lipid-lowering therapies (fibrates or niacin), lopinavir/ritonavir, or drugs (such as ketoconazole, spironolactone, or cimetidine) that lower levels or activity of steroid hormones. * Pregnancy or lactation at the time of study entry. (Pregnancy testing must be performed within 14 days prior to randomization according to institutional standards for women of childbearing potential.) * Previous malignancies unless the patient has been disease-free for 5 or more years prior to randomization and is deemed by the physician to be at low risk for recurrence. Patients with the following cancers are eligible if diagnosed and treated within the past 5 years: all in situ cancers and basal cell and squamous cell carcinoma of the skin. * Other non-malignant systemic disease that would preclude a patient from receiving rosuvastatin or would prevent prolonged follow-up. * Administration of any investigational agent within 30 days before randomization.
