Prognostic Significance of Molecular Genetic Aberrations on Chromosome Segment 11p15.5 in Non–Small-Cell Lung Cancer

Abstract

LOH in a 310-kb region on chromosome segment 11p15.5 that includes the gene for the regulatory subunit of the enzyme ribonucleotide reductase is highly predictive of poor survival from NSCLC. The future utility of analysis of the allelic status of this region may involve treatment decisions, such as the use of neoadjuvant and adjuvant chemotherapy for patients with stage I disease.
