OBJECTIVES:
* Determine bone mineral density (BMD) in patients with clinically significant early stage prostate cancer.
* Determine whether patients who have a higher level of BMD and have had a radical prostatectomy for cure are less likely to have an early relapse (i.e., less than 3 years) than those patients with a low level of BMD.
OUTLINE: This is a case-controlled study followed by a prospective, longitudinal, cohort study.
Patients undergo bone mineral density (BMD) measurements by dual-energy x-ray absorptiometry with a densitometer. Posteroanterior measurements of the total hip are also recorded.
Patients also undergo blood collection to examine markers that provide evidence of systemic disease.
Patients are followed every 6 months for 3 years.
PROJECTED ACCRUAL: A total of 40 patients will be accrued for this study.
