Osteogenic sarcoma: alterations in the pattern of pulmonary metastases with adjuvant chemotherapy.

Abstract

The number and time to appearance of pulmonary metastases were evaluated in 15 patients with osteogenic sarcoma receiving adjuvant chemotherapy with high-dose methotrexate and doxorubicin (adjuvant group). The results were compared to 33 age- and sex-matched controls (control group). The adjuvant group demonstrated a reduction in the number and a delay in the appearance of the metastases. The median time to development of metastases was 17 mo in the adjuvant group and 7 mo in the control group, and the median number of metastases was 2 and 12, respectively.
