Treatment Patterns and Clinical Outcomes among Advanced NSCLC Patients with EGFR exon 20 Insertion Mutations in China (IASLC-WCLC 2023)
Among these 59 patients, eight (13.6%) received EGFR TKIs (e.g., afatinib, icotinib, and osimertinib), two patients (3.4%) received IO therapy, eleven (18.6%) initiated platinum-based chemotherapy, fourteen (23.7%) received docetaxel, ten (16.9%) bevacizumab, five (8.5%) paclitaxel, and ten (16.9%) other chemotherapy in the 2nd LOT. The prognosis of advanced NSCLC patients with EGFR ex20ins in China was sub-optimal. The results of this study suggested there is an unmet need of novel therapy for these patients in China.Demographics, treatment patterns, and clinical outcomes of advanced NSCLC patients in ChinaTotal (N=116)Site, %Shanghai60.3Beijing39.7Age, yearMean56.2Median57.6Range27.8 - 76.1Insurance type, %Urban medical59.5Rural medical9.5Smoking status, %Current18.1Previous13.8Non-smoker62.1Cancer stage, %IIIb3.5IVa53.5IVb37.9Not specified5.2Tested for PD-L1, %Positive5.7Negative3.5Unknown74.1Patients with LOTs, %1st LOT1002nd LOT57.8Post-platinum 2nd LOT50.91st LOT (N=116), %Platinum-based chemotherapy85.3EGFR TKI2.6Immunotherapy0.9Other11.22nd LOT (N=59), %Platinum-based chemotherapy18.6EGFR TKI13.6Immunotherapy3.4Other64.4PFS of 1st LOTPFS, median (95% CI)6.2 (5.6, 8.0)Censored, %37.9PFS of post-platinum 2nd LOTPFS, median (95% CI)4.2 (2.7, 5.1)Censored, %25.4Confirmed ORR, %1st LOT14.8Post-platinum 2nd LOT10.0
