The patterns of disease extent, response to treatment, and survival rates were examined in 129 children registered as metastatic (Group IV) soft-tissue sarcoma patients on the Intergroup Rhabdomyosarcoma Study (IRS)-I protocol from November 1972 through October 1978. The patients' ages at diagnosis ranged from 3 months to 21 years (median, 10.5 years); 72 were male patients and 57 were female patients (male-to-female ratio, 1.3:1). The tumor arose in an extremity in 34 patients, the head and neck (exclusive of the orbit) in 27, the genitourinary tract in 25, the retroperitoneum or pelvis in 14, the trunk in 12, the intrathoracic region in nine, the hepatobiliary system in four, the perineum in two, and the orbit in two patients. ⋯ Only 10 of the other 84 (8%) are surviving disease-free at 2 years (P = 0.02). The presence of restricted rather than diffuse metastases at diagnosis (P = 0.02) was the only other characteristic significantly related to long-term complete remissions. One hundred and two patients (79%) died at a median of 47 weeks after diagnosis, 92 from sarcoma and ten from other causes.(ABSTRACT TRUNCATED AT 400 WORDS)
