RATIONALE: Studying samples of blood from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors predict how well patients will respond to treatment.

PURPOSE: This research study is studying DNA isolated from blood samples to see how well it influences response to rituximab in patients with follicular lymphoma treated on clinical trial ECOG-E4402.

Condition Intervention
Lymphoma Biological: rituximab Genetic: DNA analysis Genetic: gene expression analysis Genetic: polymerase chain reaction Other: laboratory biomarker analysis

Study Type: Observational
Study Design: Observational Model: Other

Further study details as provided by Eastern Cooperative Oncology Group:

Primary Outcome Measures:
  • KIR-HLA genotype predictive of antibody-dependent cell-mediated cytotoxicity (ADCC)-based cancer immunotherapy [ Time Frame: 1 year ]

Enrollment: 200
Actual Study Start Date: December 13, 2011
Study Completion Date: January 13, 2012
Primary Completion Date: January 13, 2012 (Final data collection date for primary outcome measure)
Detailed Description:


  • To test the influence of killer immunoglobulin-like receptor (KIR) and human lymphocyte antigen (HLA) genotype on response to anti-CD20 antibody lymphoma immunotherapy.

OUTLINE: DNA samples are analyzed for killer immunoglobulin-like receptor (KIR) and human lymphocyte antigen (HLA) genotyping with sequence-specific primers (SSP) by real-time PCR. KIR and HLA typing are analyzed according to KIR-HLA matched vs mismatched, KIR B haplotype content, and the number of inhibitory KIR-HLA pairs. Results are then correlated to each patient's overall response and duration of response to rituximab.


Ages Eligible for Study:   18 Years to 120 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
Samples from patients enrolled on E4402 from whom samples were submitted for research


  • Patients diagnosed with follicular lymphoma enrolled on ECOG-E4402

    • Treated with single-agent rituximab; the trial compared two different rituximab-dosing strategies - maintenance vs retreatment as needed
  • Available germline DNA samples isolated from peripheral blood as well as clinical evaluation of disease status prior to and at initial response to the therapy
