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.

Condition Intervention
Prostate Cancer
Other: laboratory biomarker analysis

Study Type: Observational
Official Title: Evaluation of PSA Antibody on E9802: Confirmation and Concordance

Further study details as provided by National Cancer Institute (NCI):

Primary Outcome Measures:
  • PSA antibody levels are compared between baseline and follow-up at 12 weeks, as well as 24 weeks, using Wilcoxon signed-rank test [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Concordance of PSA antibody assessment between the ECOG Immunology Laboratory and the NCI Immunology Laboratory; concordance correlation coefficient will be computed [ Designated as safety issue: No ]

Estimated Enrollment: 20
Study Start Date: November 2012
Estimated Primary Completion Date: December 2012 (Final data collection date for primary outcome measure)
Detailed Description:



  • To evaluate changes in prostate-specific antigen (PSA) antibody levels over time among patients treated on ECOG-E9802.


  • 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.
