Aim: Positive outcomes for paediatric rhabdomyosarcoma (RMS) were high in Sweden during the 1990s, but the last decade has seen decreasing trends in overall survival rates. We investigated the incidence, patient and disease characteristics, treatment and outcome of RMS to see whether any reason could be found for this decline.
Methods: This study included 210 children under the age of 15 who were diagnosed with RMS and whose details were recorded in the population-based Swedish Childhood Cancer Registry from 1984 to 2010.
