Further study details as provided by Eastern Cooperative Oncology Group:

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 [ Time Frame: 12 weeks ]

Secondary Outcome Measures:
  • Concordance of PSA antibody assessment between the ECOG Immunology Laboratory and the NCI Immunology Laboratory; concordance correlation coefficient will be computed [ Time Frame: 12 Weeks ]

Enrollment: 20
Actual Study Start Date: December 7, 2012
Study Completion Date: January 7, 2013
Primary Completion Date: January 7, 2013 (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.
