Studying Stored Samples From Patients With Localized Prostate Cancer Treated on Clinical Trial NCI-00-C-0154

Data Analysis for 00-C-0154, A Randomized Phase II Study of a PSA-based Vaccine in Patients With Localized Prostate Cancer Receiving Standard Radiotherapy

RATIONALE: Studying samples of blood in the laboratory from patients before and after treatment may help doctors learn more about the effects of the treatment on cells.

PURPOSE: This clinical trial is studying samples collected from patients with localized prostate cancer who received treatment on clinical trial NCI-00-C-0154.

Study Overview

Detailed Description

OBJECTIVES:

Primary

  • Evaluate the formation of antibody complexes in serum samples taken before initiation of treatment and after completion of therapy in prostate cancer patients previously enrolled on clinical trial NCI-00-C-0154.
  • Evaluate immunologic response.

Secondary

  • Clone the underlying tumor antigens discovered through SEREX.

OUTLINE: Samples previously collected on clinical trial NCI-00-C-0154 (whole blood, serum, and peripheral mononuclear blood cells) are analyzed for immunologic responses and evidence of formation of anti-tumor antibodies. Western blot is used to detect any evidence of vaccine-induced autoantibody responses. If there is an indication of response, SEREX is used to clone the underlying antigens.
