Eligibility Criteria
Inclusion Criteria
- Histologically or cytologically confirmed diagnosis of adenocarcinoma of the prostate
- Planned treatment with radiation therapy to include external beam and/or brachytherapy with curative intent (total dose ≥60 Gy). A portion of the rectum must receive at least 60 Gy.
- Age at least 18 years
- Karnofsky Performance Status (KPS) ≥ 70
- No history of prior radiotherapy to the prostate or rectum
- History of prior malignancy, if likely to live at least 4 years, is acceptable.
- No evidence of distant metastases
- Patients may be taking an HMG-coA-reductase inhibitor, but to be eligible, they must be able to be changed to lovastatin 20 mg/day, with the permission of their prescribing physician.
- Creatine kinase < 5 times upper normal limit
- Sufficient renal function defined as calculated creatinine clearance ≥ 30ml/min
- transaminases < 3 times upper normal limit
Exclusion Criteria
- Planned abdomino-perineal resection after radiotherapy
- Contraindication to an HMG-coA-reductase inhibitor
- Major medical or psychiatric illness, which in the investigator's opinion, would prevent completion of treatment and would interfere with follow-up.
