PG - 405-9 LID - 10.1016/j.cancergen.2012.04.003 [doi] AB - The observation of an apparently non-clonal abnormal cell in a cytogenetic study for a hematologic neoplasm opens the possibility of a small, or slowly proliferating, abnormal clone. Many laboratories analyze additional cells or reflex to fluorescence in situ hybridization (FISH) to evaluate this possibility further. In a retrospective study of 500 cases with a non-clonal abnormal cell identified in a 20-cell analysis, we found that the benefit of additional metaphase analysis was limited to specific categories of abnormal karyotypes, including those with a complex karyotype or a classic abnormality known to be a recurring finding in hematologic neoplasms, and excluding all other categories.
