Moreover, studies reporting higher prevalences of LNM among both RMS and patients with NRSTS tended to include more advanced disease populations, characterised in the RMS group by alveolar histology,24PAX3/PAX7–FOXO1 fusion positivity,61, 62, 63 older patients,64, 65, 66 and larger tumours,15,28,29,67, 68, 69 and in the NRSTS group by specific histologic subtypes (e.g., DSRCT) and more invasive tumours.31 Here, PAX7 is linked to neoplasm.
