[The reproduction in France of Rosen's protocol for osteosarcomas].

: The authors treated 188 patients with osteosarcoma by chemotherapy followed by surgery and additional chemotherapy (Rosen's T regimen). In 14% of cases, infectious, neurologic or cardiac complications were observed, which resulted in death in 2% of the patients. Forty-six per cent responded well to the primary chemotherapy, 76% of which are alive and disease-free, as opposed to merely 42% of the bad responders.
