eligible for this study if definitive treatment or the condition has been completed.
b. Patients with organ-confined prostate cancer with no evidence of recurrent or
progressive disease based on prostate specific antigen (PSA) values are also eligible
for this study if hormonal therapy has been initiated or a radical prostatectomy has
been performed.

- Have prior positive test for the human immunodeficiency virus (HIV).

- Have gastrointestinal disease or prior surgery, which may affect the ability of the
