Figure 2. Effects of EGFR-inhibition and/or radiotherapy on tumor growth delay.

Figure 2

Kaplan-Meier survival curves showing the effect of C225 and/or radiotherapy on the tumor growth of 4 SCCNij lines: A) SCCNij202, B) SCCNij167, C) SCCNij153, D) SCCNij185. Events were scored when the tumor volume tripled compared to the start volume and % tumor response represents the percentage of tumors that did not reach the event. Tumors were treated with C225 (1 mg i.p.), 10 or 20 Gy radiotherapy, or concurrent treatment of C225 and radiotherapy. C225 was given 24h before radiotherapy. Number of animals per group varied from 7 to 14.
