Bone scintigraphy in patients with osteogenic sarcoma. Cooperative Osteogenic Sarcoma Study Group COSS 80

Preliminary results of a comprehensive analysis of bone scans in osteogenic sarcoma are presented. The scintigraphic data from 60 of 184 patients of the COSS-80 study were used for evaluation. The method seems to be appropriate to detect sensitively and early a therapy-induced decrease of tumor viability and extent. An optimized procedure is proposed.
