Abstract
UNLABELLED: The role of preoperative radiotherapy was evaluated in 16 cases with soft tissue sarcoma and 13 cases with osteosarcoma. Nine osteosarcoma cases underwent radiotherapy of whole lesion, and 4 cases had radiotherapy only of the surgically incurable portion. There were no local recurrences in M0 cases, but skin necrosis occurred in the whole radiation group. As for the soft tissue sarcomas, local recurrence was not seen in virgin cases, but two cases which had received previous treatment showed local recurrence. There were no cases with severe side effects. CONCLUSION: 1. Partial radiotherapy was effective as preoperative treatment for osteosarcoma. 2. preoperative radiotherapy is better than postoperative radiotherapy from many standpoints.
