Clinical response and classification of the two groups.

Group	Clinical response	No. of patients
Responder
	CR	2
	PR	13
Non-responder
	MR	4
	NC	12
	PD	11
Total		42

Responder group, CR or PR; non-responder group, PD, NC or MR. CR, complete response (shrinkage rate 100%); PR, partial response (shrinkage rate ≥50 to <100%); MR, minor response (shrinkage rate ≥25 to <50%); NC, no change (shrinkage rate ≥−25 to <25%); PD, progressive disease (shrinkage rate ≤−25%). Shrinkage rate, tumor shrinkage rate in pulmonary metastasis. Efficacy rate 35.7%.
