Brief Summary:
RATIONALE: Studying samples of blood or tumor tissue from patients with cancer in the laboratory may help doctors identify and learn more about biomarkers related to cancer.
PURPOSE: This clinical trial studies prostate-specific antigen (PSA) antibody levels in samples from patients treated for prostate cancer on trial ECOG-E9802.
PURPOSE: This clinical trial studies prostate-specific antigen (PSA) antibody levels in samples from patients treated for prostate cancer on trial ECOG-E9802.
Detailed Description:
OBJECTIVES:
Primary
* To evaluate changes in prostate-specific antigen (PSA) antibody levels over time among patients treated on ECOG-E9802.
Secondary
* To characterize the concordance of PSA antibody assessment between the ECOG Immunology Laboratory and the NCI Immunology Laboratory.
OUTLINE: Previously tested samples are evaluated for changes in PSA antibody levels over time (from baseline to follow-up at 12 and 24 weeks) at the ECOG Immunology Laboratory and the NCI Immunology Laboratory. Results are compared between the laboratories.
