[Experience with protocol T10 in the pediatric service at the Gustave-Roussy Institute]

Abstract

Between April and September 1986, 60 patients with osteosarcoma have been treated according to the T10 protocol in the Pediatrics Department of the Gustave Roussy Institute in Villejuif, France. Limb sparing could be achieved in 49 patients and amputation was necessary in 11. The necrosis of the primary tumor was total or subtotal in 33 cases and incomplete in the 27 others. With a median follow-up of 28 months, the actuarial survival is 85% at 48 months and the actuarial disease-free survival is 58%; the disease-free survival of "good responders" is 75% and 32% for "bad responders".
