RATIONALE: Collecting and storing samples of blood from patients and their brothers with cancer to study in the laboratory may help doctors learn more about changes that may occur in DNA and identify biomarkers related to cancer.

PURPOSE: This laboratory study is looking at changes in DNA in patients and their brothers with prostate cancer.

Condition Intervention
Prostate Cancer
Genetic: polymorphism analysis
Other: laboratory biomarker analysis

Study Type: Observational
Study Design: Observational Model: Other
Time Perspective: Retrospective
Official Title: Assessment of SNP Genotypes in Men With Prostate Cancer

Further study details as provided by Eastern Cooperative Oncology Group:

Primary Outcome Measures:
  • Frequency of single nucleotide polymorphism (SNP) genotypes [ Time Frame: 1 month ]
  • Age of onset of prostate cancer in patients and their affected siblings [ Time Frame: 1 month ]

Enrollment: 646
Actual Study Start Date: May 23, 2006
Study Completion Date: May 30, 2007
Primary Completion Date: May 30, 2007 (Final data collection date for primary outcome measure)
Detailed Description:


  • Determine the frequency of single nucleotide polymorphism (SNP) genotypes in patients with prostate cancer, their affected siblings, and an unaffected healthy population (control).
  • Determine the age of onset of prostate cancer in affected probands and affected siblings.
  • Determine the penetrance or likelihood that given SNPs will result in disease in affected siblings based upon Mendelian genetics.
  • Determine the odds ratio of developing prostate cancer in the presence of SNPs.
  • Determine SNP genotypes in patients enrolled on ECOG-E3805, a prostate phase III study enrolling men with D2 prostate cancer treated with androgen-ablation therapy alone or androgen-ablation therapy with chemotherapy, and correlate them with disease progression (i.e., androgen independence).

OUTLINE: This is an open-label, multicenter study. Patients are stratified according to ethnicity, age at diagnosis, and Gleason score.

Patients, their affected siblings, and healthy participants (controls) undergo collection of blood samples. Genomic DNA is extracted from whole blood and sequenced for single nucleotide polymorphisms (SNPs) in Akt and mdm-2 genes. SNP data is correlated with clinical and biographical data.

PROJECTED ACCRUAL: A total of 500 patients (250 probands and 250 siblings) and 146 healthy participants (controls) will be accrued for this study.
