Chromosomal Rearrangements Help Distinguish Between Lung Independent Primary Tumors and Metastasis

For patients with multiple tumors, that distinction could mean the difference between early stage cancer that may be cured by surgery and incurable late-stage disease. The research is published this week in the Journal of Clinical Oncology. Dr. Dennis Wigle, the study's senior author, comments.
