This was achieved (Table 2) with the association of the expression of only 8 genes: CTNS, DERL-1, FAM114A2, KIAA1549, P2RX1, PITPNA, PSMD11, and WEE1. As an example, for patient A with a pCR and patient B with no pCR, the correlation between patient A’s tumor cells and the reference cell lines showed r = 0.93 with the sensitive HCC2218 cells, whereas we obtained r = −0.36 with the resistant HCC1419 cells, classifying it as a sensitive tumor (Figure 1A). Here, PITPNA is linked to neoplasm.
