EGFR was detected in 6 patients (3 on tumor and 3 in blood NGS)....Single agent checkpoint inhibitors seem to have a limited impact in treatment in patients with driver mutations....We do see benefit in patients who received PD1/PDL1 inhibitors in combination with chemotherapy with/ without Bevacizumab. In conclusion, patients progressing on EGFR TKIs who are planned for immunotherapy should always be given in combination with chemotherapy+/- Bevacizumab.
