title: 7 year-survival of 2 cases of multicentric or metastatic osteosarcoma.
abstract: Osteosarcoma is a fatal disease. Neoadjuvant chemotherapy combined with irradiation treatment provide a better survival. In the Faculty of Medicine, Ramathibodi Hospital, the overall 9 year survival probability was 55 per cent among 130 cases of more than Enneking stage II osteosarcoma. Between 15 cases of bony metastases, there were 2 cases which were classified as multifoci osteosarcoma or osteosarcomatosis. These two cases developed second bone disease, 32 and 38 months after initial diagnosis and survived for 84 and 88 months with one patient also developing pulmonary metastasis. Both of them are still alive and in very good health.
