One hundred and thirty patients with osteogenic sarcoma were studied
clinically, roentgenographically, and pathologically. Prognosis by each of
ten factors was analyzed with the Wilcoxon test. The test yielded p smaller
than 0.05 in a comparison between the survival curves of patients fifteen
years old or younger and that of patients over fifteen, but other
comparisons did not yield p smaller than 0.05. The actual five-year
survival rate was 25.5 per cent (twenty-six of 102 patients who had radical
surgery). Our therapeutic regimen for osteogenic sarcoma at the present
time consists of regional perfusion, amputation, bronchial artery infusion,
and systemic administration of anticancer agents.
