Figure 1 showed that from 62 samples after 3 cycles of NAC, 44 samples 70.96 had negative NAC response and 18 samples 29.03 had positive NAC response. Figure 2 Positive Response Types towards NAC: PR; cCR; pCR Figure 2 showed positive type responses toward NAC, from 18 samples who showed positive response, 16 samples 25.80 had partial response PR, while 2 samples 3.23 had clinical complete response cCR, which later were proven to be pathological complete response pCR. 4.3 mRNA Caspase-3 Level Decrease Correlation with Negative Chemotherapy Response Prechemotherapy and postchemotherapy of mRNA Caspase-3 level were measured to determine the difference of mRNA Caspase-3 levels. Data is shown in Table 2.

T- paired test result showed a normal and homogeneous data. There was a significant decrease of mRNA Caspase-3 level 0.87±1.96 pgmL, p 0.05. Phi and Cramer’s V Test was performed to determine the role of post 1st cycle NAC mRNA Caspase-3 level decrease as a negative chemotherapy response risk in LABC. Data transformation from numeric to categorical was performed. Analysis results is shown in Table 3.

Phi and Cramer’s V Correlation Test showed post 1st cycle NAC mRNA Caspase-3 level decrease as a negative chemotherapy response risk in LABC r=0.343; p=0.007. The Relative Risk RR was 4.796 1.473-15.438; CI 95.
