Abstract
Background
Allelic losses of tumor suppressor genes or the chromosomal regions harboring them in the DNA of tumor cells may become useful postoperative prognostic indicators.
Methods
To examine whether specific allelic losses correlate with postoperative survival in a five-year prospective follow-up, we tested tumors from a cohort of 504 breast cancer patients for allelic loss of 18 microsatellite markers representing either known tumor suppressor genes or regions where genetic alterations are frequent in breast tumors.
Results
Patients with allelic loss at 1 p34, 3p25, 8p22, 13q12, 17pl3.3, or 17q21.1 had a significantly higher risks of postoperative mortality compared with those whose tumors retained both alleles at those loci (at lp34, the 5-year mortality rate was 23% among patients with loss vs 10% with retention, p=0.0100; at 3p25, 22% vs 9%, p=0.0014; at 8p22, 24% vs 7%, p=0.0177; at 13ql2, 19% vs 8%, p=0.0093; at 17pl3.3, 19% vs 9%, p=0.0078; and at 1 Zq21.1, 17% vs 10%, p= 0.0475).
Conclusion
Allelic losses at these loci can serve as negative prognostic indicators to guide postoperative management, especially in the selection of those who will benefit from intensive adjuvant therapies.
