Abstract:
Objective To explore the curative effect of stereotactic conformal radiotherapy (SCR) for extracranial tumors. Methods Eighty-six patients with extracranial tumors underwent SCR from May 1997 to August 2002. The clinical target volume (CTV) of tumors ranged from 0.2 cm3 to 232 cm3, with a mean of 27.6 cm3. The prescribed dose to the planning target volume (PTV) was 3～12 Gy (mean,5.3 Gy),which were prescribed in 1～10 fractions. Results No patient died during the treatment. Karnofsky performance scores (KPS) ranged 10～90 (mean,60) and 20～100 (mean,82) before and after the treatment. Follow-up for 1～5 years showed complete remittence (CR) in 25 cases, partial remittence (PR) in 49 cases, no change in 9 cases, and progressed in 3 cases. Conclusions SCR is an effective method in the management of extracranial tumors.
