The results indicate that the RT-PCR assay is a reliable method for the detection of the PAX3-FKHR fusion transcript of alveolar RMS in formalin-fixed, paraffin-embedded tissue.     ///    Detection of PAX3-FKHR and PAX7-FKHR fusion transcripts in rhabdomyosarcoma by reverse transcriptase-polymerase chain reaction using paraffin-embedded tissue..     ///    "Oligonucleotide primers corresponding to the regions of PAX3, PAX7 and FKHR were used for the detection of PAX3-FKHR and PAX7-FKHR chimeric messages. "    ///    The PAX3-FKHR chimeric message was detected in all three cases of alveolar RMS but not in any of the 12 embryonal and two pleomorphic RMS cases.     ///    "We describe the results of RT-PCR analysis of PAX3-FKHR and PAX7-FKHR chimeric messages in formalin-fixed, paraffin-embedded tissue samples from 17 RMS cases.
