Radiation treatment of osteoclastoma.

ABSTRACT

JC------------ABSTRACT------------------------- P4 Osteoclastoma seen between 1965 and 1984 is presented. All patients received megavoltage therapy using Telecobalt. Tumour dose of 45 Gy to 55.3 Gy in 15 to 18 fractions had been delivered. All patients had quantitation of pre-treatment tumour volume and post-treatment response using a radiographic grid. CT scan measurements have complimented the grid quantitation in recent years. Follow through visits from 5 to 24 years post-treatment (mean follow up 9.2 years) have shown optimum tumor regression, bone recalcification and restitution of joint functions amongst these patients. No case of bone sarcoma has been detected. Our observations lead us to support megavoltage radiation therapy as the treatment of choice for accessible and inaccessible osteoclastoma.
