Tumor response in soft tissue sarcoma–bearing rats after ILP with IL-2 and melphalan over a total period of 10 days

Treatment	Response rate* (%)
	PD	NC	PR	CR	RR

IL-2 (n = 9)	100	—	—	—	0
Melphalan (n = 6)	66	17	17	—	17

Abbreviation: RR, response rate (PR plus CR).

Responses were scored as described in Materials and Methods.

P < 0.05 compared with melphalan alone.
