Would you recommend prophylactic retro-peritoneal RT in an adolescent with paratesticular rhabdomyosarcoma, s/p radical inguinal orchiectomy without a lymph node dissection?  

If a staging RPLND is NOT performed, is there a role for prophylactically irradiating the lymph nodes, even in the setting of a negative PET/CT at diagnosis in a >10 year old male with Rhabdomyosarcoma? If so, what RT field would you recommend?
