Abstract
Distant metastases were documented in 83 of 161 children with rhabdomyosarcoma seen between 1953 and 1974. Of these, 31 had metastases at diagnosis (Group IV) and 7 were noted to have metastases only at autopsy. Only 6 are living with no evidence of disease activity at 6, 20, 77, 85, 105, and 112 months from time of metastasis. One child is living with disease at 98 months. Late deaths occurred in 2 at 31 and 41 months after metastasis. Sixty-four of the 66 deaths occurred within 24 months. The median durations of life after metastasis were less than 9 months in Groups I and II patients, less than 6 months in Group III patients, and about 12 months in 31 Group IV patients. The median time to metastasis in Groups I, II, and III patients was 9 months.
