title: Clonal evolution as pathogenetic mechanism in relapse of primary CNS lymphoma.
abstract: Comparative investigation of immunoglobulin (Ig) heavy chain gene rearrangements and DNA sequence analyses of a primary lymphoma of the CNS (PCNSL) and its recurrence revealed that both tumors used the same Ig gene segment. In addition to shared somatic mutations, the primary and the recurrent PCNSLs harbored somatic mutations unique to each tumor. Clonal evolution rather than subclone selection appears to underlie the development of tumor recurrence in this case.
