Efficacy of PD-1 blockade plus chemotherapy in patients with oncogenic-driven non-small-cell lung cancer.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPD-1 blockade plus chemotherapy has become the first-line standard of care for patients with advanced non-small-cell lung cancer (NSCLC) without oncogenic drivers. Oncogenic-driven advanced NSCLC showed limited response to PD-1 blockade monotherapy or chemotherapy alone. Whether NSCLC patients with oncogenic drivers could benefit from PD-1 blockade plus chemotherapy remains undetermined.
methodsThree hundred twelve NSCLC patients with at least one oncogenic driver alteration received PD-1 plus chemotherapy or each monotherapy were retrospectively identified. Objective response rate (ORR), progression-free survival (PFS), and overall survival (OS) were compared to evaluate the therapeutic outcomes differences among patients with different oncogenic drivers.
resultsOne hundred sixty-two patients received PD-1 blockade plus chemotherapy, 57 received PD-1 blockade monotherapy and 93 received chemotherapy alone were included. Oncogenic driver mutations including KRAS (31.4%), EGFR (28.8%), HER2 (14.7%), BRAF (10.6%), RET (7.4%), and other mutations (7.1%) were identified. Patients with oncogenic drivers who received PD-1 blockade plus chemotherapy had significantly better outcomes compared to those received PD-1 blockade or chemotherapy alone (ORR: 51% vs. 18% vs. 25%, P < 0.001; median PFS: 10.0 [95% CI: 8.9-12.6] vs. 3.7 [95% CI: 2.9-5.1] vs. 5.3 [95% CI: 4.5-6.2] months, P < 0.001; median OS: 26.0 [95% CI: 23.0-30.0] vs. 14.3 [95% CI: 9.6-19.8] vs. 16.1 [95% CI: 11.6-21.9] months, P < 0.001). The superior efficacy was consistently found in separate analyses for patients received first-line and second/third line treatments. Among individual gene alterations, patients with KRAS, EGFR, or BRAF mutations treated with PD-1 blockade plus chemotherapy achieved markedly improved PFS and OS than those received PD-1 blockade or chemotherapy alone. Multivariate Cox regression analysis revealed that PD-1 blockade plus chemotherapy was independently associated with better PFS and OS.
conclusionPD-1 blockade plus chemotherapy demonstrated superior efficacy than PD-1 blockade monotherapy or chemotherapy alone in patients with oncogenic-driven advanced NSCLC, particularly in KRAS, EGFR and BRAF subgroups. These findings suggest that PD-1 blockade plus chemotherapy may be considered as an optional treatment option for patients without available targeted therapies.
