Group	SBRT (n = 36)	FRT (n = 36)	χ²	P
CR (n)	5	2
PR (n)	16	10
SD (n)	12	12
PD (n)	3	12
Response rate (%)	58.33 (21/36)	33.33 (12/36)	4.531	0.033*
Disease control rate (%)	91.67 (33/36)	66.67 (24/36)	6.821	0.009*

CR complete response, PR partial response, SD stable disease, PD progressive disease. Response rate was the ratio of was the sum of CR and PR to whole patients. Disease control rate was the ratio of the sum of CR, PR, and SD to whole patients
