Pembrolizumab in advanced NSCLC patients with poor performance status and high PD-L1 expression: OLCSG 1801.
Trial report in International journal of clinical oncology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
backgroundThe role of pembrolizumab in the treatment of poor performance status (PS) patients remains unclear. PATIENTS AND
methodsWe conducted a phase II trial to investigate the efficacy and safety of pembrolizumab as first-line therapy for non-small-cell lung cancer (NSCLC) patients with PSs of 2-3 and programmed cell death ligand 1 (PD-L1) expression ≥ 50%. The primary endpoint of this study was the objective response rate (ORR).
resultsFourteen patients treated at eight institutions were enrolled. Most patients had PS 2 (12/14; 86%) and others had PS 3 (2/14; 14%). The ORR was 57.1% (95% confidence interval 28.9-82.3%), which met the primary endpoint. The median progression-free survival (PFS) and 1-year PFS rates were 5.8 months and 20.0%, respectively. At the time of data cut-off, one patient had received treatment for more than 1 year; another patient had received treatment for more than 2 years. Nine patients had improved PS with treatment (Wilcoxon signed-rank test, p = 0.003). Two patients had immune-related adverse events ≥ grade 3: grades 5 and 3 elevation in alanine and aspartate aminotransferases. Two PS 3-stage patients were diagnosed with clinically progressive disease prior to initial computed tomography; both died within 2 months.
conclusionPembrolizumab was effective for the treatment of NSCLC patients with a poor PS and PD-L1 level ≥ 50%. However, given the poor outcomes of the PS 3 patients, the drug is not indicated for such patients. Adverse events, including liver dysfunction, should be carefully monitored.
