*The ratio between the samples and control human RNA (Universal Human Reference RNA; Stratagene, La Jolla, California, USA); †evaluation was impossible because only tumour tissue was excised and no invasive front or stromal tissue were seen.
IHC, immunohistochemistry; MPNST, malignant peripheral nerve sheath tumour; ND, not done; RT-PCR, reverse transcription polymerase chain reaction.
