第一次特3个月就耐药，其中第一个月联合了12天 xl184，效果最明显，会不会其实是XL184在起作用？

( h [- ^2 k% s0 T! Y7 m: q9 h Results: The T790M mutation was detected in 21/64 (32.8%) p in the erlotinib arm and 26/59 (44.1%) in the chemotherapy arm. PFS was 12.1 m for p with mutant T790M in the erlotinib arm, 8.8 m for p with wt T790M in the erlotinib arm, 6.3 m for p with mutant T790M in the chemotherapy arm, and 4.5 m for p with wt T790M in the chemotherapy arm (P<0.0001). OS was not reached for p with mutant T790M in the erlotinib arm, 16.1 m for p with wt T790M in the erlotinib arm, 22.6 m for p with mutant T790M in the chemotherapy arm, and 18.4 m for p with wt T790M in the chemotherapy arm (P=0.04). Conclusions: Our unexpected finding that p with EGFR compound mutants attain the maximum benefit from erlotinib suggests a need for more sensitive assays to detect EGFR compound mutants and for studies of inhibitors targeting the EGFR T790M mutation. Whole genome sequencing may provide greater understanding of the genetic factors involved in the differences in OS.
