Abstrakt: Background: The upfront treatment of non-oncogene-addicted NSCLC relies on immunotherapy alone (ICI) or in combination with chemotherapy (CT-ICI). Genomic aberrations such as KRAS, TP53, KEAP1, SMARCA4, or STK11 may impact survival outcomes.
Methods: We performed an observational study of 145 patients treated with first-line IO or CT-ICI for advanced non-squamous (nsq) NSCLC at our institution tested with an extensive lab-developed NGS panel. The primary objective was to assess the clinical outcomes of STK11-mutated patients. Then, we performed an external validation through the public OAK/POPLAR dataset, including nsq NSCLC patients treated with single-agent ICI or CT.
Results: Most patients were male (59.7 %), former smokers (61.1 %), with ECOG PS 0-1 (84 %), and received first-line CT-IO (58.6 %). 44.8 % had a mutation in KRAS, 21.4 % in KEAP1, 50.3 % in TP53, 13.1 % in SMARCA4, and 14.4 % in the STK11 gene. The mOS was 8 mo. (95 % CI, 5-16.7) for STK11 mutated pts and 17.3 mo. for STK11 wild-type patients (95 % CI, 8.9-24.4) (p = 0.038). TP53 (8.3 vs 17.3), KRAS (9.2 vs 15.9), and KEAP1 (8.9 vs 15.9) mutated patients evidenced a trend for dismal mOS. SMARCA4 status had no impact on mOS. STK11 mutations were detrimental to OS in the univariate (HR 1.74, p = 0.041) and multivariate model (HR 1.97, p = 0.025) after adjusting for sex, age, ECOG PS, treatment (ICI vs CT-ICI), KRAS, KEAP1, TP53, and SMARCA4 status. Genomic alterations did not impact the mPFS in our cohort. Within the OAK/POPLAR dataset, STK11 mutations (60/818 pts) were significantly associated with increased death risk in the univariate (HR 2.01, p < 0.001) and multivariate model (HR 1.66, p = 0.001) after adjusting for age, sex, treatment (ICI vs CT), KRAS, KEAP1, TP53, and SMARCA4 status.
Conclusion: STK11 aberrations hampered the mOS of nsq NSCLC patients treated with first-line ICI or CT-ICI. The negative prognostic impact seems to be unrelated to ICI administration.
