Evaluation of PSA Antibody on E9802: Confirmation and Concordance
- 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.
PSA antibody levels are compared between baseline and follow-up at 12 weeks, as well as 24 weeks, using Wilcoxon signed-rank test
