Résumé
Anti-programmed cell death protein (death-ligand) 1 [PD-(L)1] therapy alone [cancer immunotherapy (CIT)-mono] or combined with platinum-based chemotherapy (CIT-chemo) is used as the first-line treatment for patients with metastatic non-small-cell lung cancer (NSCLC). Our study compared clinical outcomes with CIT-mono versus CIT-chemo in the specific clinical scenario of non-squamous (Nsq)-NSCLC with a high PD-L1 expression of ≥50% [tumor proportion score (TPS) or tumor cells (TC)].
This was a retrospective cohort study using a real-world de-identified database. Patients with metastatic Nsq-NSCLC with high PD-L1 expression initiating first-line CIT-mono or CIT-chemo between 24 October 2016 and 28 February 2019 were followed up until 28 February 2020. We compared overall survival (OS) and real-world progression-free survival (rwPFS) using the Kaplan-Meier methodology. Hazard ratios (HRs) were adjusted (aHR) for differences in baseline key prognostic characteristics using the inverse probability of treatment weighting methodology.
Patients with PD-L1-high Nsq-NSCLC treated with CIT-mono (n = 351) were older and less often presented with de novo stage IV disease than patients treated with CIT-chemo (n = 169). With a median follow-up of 19.9 months for CIT-chemo versus 23.5 months for CIT-mono, median OS and rwPFS did not differ between the two groups [median OS: CIT-chemo, 21.0 months versus CIT-mono, 22.1 months, aHR = 1.03, 95% confidence interval (CI) 0.77-1.39, P = 0.83; median rwPFS: CIT-chemo, 10.8 months versus CIT-mono, 11.5 months, aHR = 1.04, 95% CI 0.78-1.37, P = 0.81]. CIT-chemo showed significant and meaningful improvement in OS and rwPFS versus CIT-mono only in the never-smoker subgroup, albeit among a small sample of patients (n = 50; OS HR = 0.25, 95% CI 0.07-0.83, interaction P = 0.02; rwPFS HR = 0.40, 95% CI 0.17-0.95, interaction P = 0.04).
Except in the subgroup of never-smoker patients, sparing the chemotherapy in first-line CIT treatment does not appear to impact survival outcomes in Nsq-NSCLC patients with high PD-L1 expression.
