title: Fragile sites and structural rearrangements in cancer.
abstract: We retracted information from a computerized databank which contains the cytogenetic findings of 17,000 patients with leukemia and lymphoma. Cytogenetic data from patients with solid tumors were compiled from Dr. Mitelman's catalogue on "Chromosome aberrations in cancer". We compared the observed distribution of breaks in chromosome bands involved in structural rearrangements with the random distribution of breaks generated by Monte Carlo simulation and showed that a majority but not all of the bands known to contain a fragile site are involved in structural aberrations in cancer and that some of them are associated with specific chromosome structural changes in specific types of cancer.
