Figure 2

Ki-67 proliferative index (PI) on CTVT sample before treatment (wk0) and during treatment (wk1–2). Ki-67 PI of conventional protocol revealed variable values, on the other hand, modified combination protocol shown the decreasing trend. Moreover, Ki-67 PI of modified combination protocol in wk-2 PT was lower than the conventional protocol significantly (a = 0.024) (A). The treatment time of modified combination protocol was shorter than conventional protocol significantly (b = 0.019) (B) (Mann-Whitney U-test was used to determine the significance of differentiation between the conventional and modified combination chemotherapeutic protocols, a, bp < 0.05).
