Abstract

Detection of characteristic chromosomal translocations has aided diagnosis of the small round cell tumors of childhood and may help to stratify patients into clinical groups. The detection of the abnormalities by classical cytogenetic techniques has been supplemented by fluorescent in situ hybridization and reverse transcriptase polymerase chain reaction (RT-PCR). These techniques allow diagnoses to be made using only very small amounts of tumor tissue. We here describe a technique for the rapid and specific detection by modified reverse transcriptase polymerase chain reaction of characteristic chromosomal translocations of alveolar rhabdomyosarcoma with small amounts of formalin-fixed tissue as the starting material. Of 27 samples studied, 4 cases are described in which the detection of translocations by this method cast doubt on the original histopathological diagnosis. These cases demonstrate the critical diagnostic importance of the detection of these translocations in rhabdomyosarcoma.
