The most common neoplasm of the soft tissue in children is rhabdomyosarcoma, followed by fibrosarcomas.
Soft tissue refers to the soft connective or supporting tissues, such as muscle.
The corresponding rate for the US was 1.0 per 100,000. Rhabdomyosarcoma had an incidence rate of 0.5 per 100,000 NJ and US children. Incidence and Mortality Trends Figure 12 shows the incidence and mortality trends for soft-tissue sarcomas. The numbers of these cancers are so low that differences of just one or two cases each year produces fluctuations in the graph seen in Figure 11 which cannot be interpreted as increasing or decreasing trends but rather as normal variation over time. The incidence rates for NJ and the US were essentially constant at about 1.0 per 100,000 throughout the period.
