Fig 4

Conceptual graph showing tumor volume after TKI treatment. TKI, tyrosine kinase inhibitors; PD, progressive disease. T0, the time of TKI initiation; T1, the time of first follow up CT after two cycles of TKI; T2, the time of second follow up CT after four cycles of TKI; Tp, the time when the lesion reached a nadir; Vn, the volume measurements at time Tn (n = 0, 1, 2, r, p); T1, T2, Tr, and Tp, respectively V1, the tumor volume at the time of T1; V2, the tumor volume at the time of T2; TTN, time to nadir; TTP, time to progression; RR, response rate; PR, progression rate
