S9719 Gene Damage Following Chemotherapy in Women With Stage II or Stage III Breast Cancer
COMPLETED
NCT00003095
OBSERVATIONAL
S9719: Clonal Hematopoiesis as a Marker of Genetic Damage Following Adjuvant Chemotherapy for Breast Cancer: Pilot Study to Evaluate Incidence. Ancillary to S9623
RATIONALE: Drugs used in chemotherapy for breast cancer may damage the genes of cells. This may lead to the development of secondary cancers.
PURPOSE: Pilot study to evaluate the degree of gene damage following chemotherapy in women with stage II or stage III breast cancer involving four to nine axillary lymph nodes.
