Investigator: Petersdorf, Effie
Institution: Fred Hutchinson Cancer Research Center Clinical Research
Objective: To determine the clinical significance of SNPs in immune respone genes in patients diagnosed with cancer. SNPs will be genotyped using PCR-based platforms.

The frequency of SNPs in the cases and controls will be determined in order to assess the effect of SNPs on cancer survival and response to therapy.
