(a) Kaplan-Meier estimates of overall survival from the time of diagnosis according to tumor tissue of origin in all patients with high-grade osteosarcoma [,173 (256 with extraskeletal involvement and 3,917 with skeletal involvement)]. (b) Kaplan-Meier estimates of overall survival from the time of diagnosis according to tumor tissue of origin in patients aged from 0 to 17 years [,672 (6 with extraskeletal involvement and 1,666 with skeletal involvement)]. (c) Kaplan-Meier estimates of overall survival from the time of diagnosis according to tumor tissue of origin in patients aged from 18 to 32 years [ (24 with extraskeletal involvement and 825 with skeletal involvement)]. (d) Kaplan-Meier estimates of overall survival from the time of diagnosis according to tumor tissue of origin in patients aged from 33 to 59 years [ (72 with extraskeletal involvement and 752 with skeletal involvement)]. (e) Kaplan-Meier estimates of overall survival from the time of diagnosis according to tumor tissue of origin in patients aged from 60 to 99 years [ (154 with extraskeletal involvement and 674 with skeletal involvement)].
