Concurrent Chemoradiotherapy with Daily Low-Dose Carboplatin in Older Patients with Unresectable Locally Advanced Non-Small-Cell Lung Cancer: Clinical Outcomes and Prognostic Significance of Systemic Inflammation Markers.
Article in Current oncology (Toronto, Ont.), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Older patients with unresectable locally advanced non-small-cell lung cancer (NSCLC) frequently receive concurrent chemoradiotherapy (CCRT) with daily low-dose carboplatin; however, real-world data on its efficacy, safety, and prognostic factors remain limited. We aimed to retrospectively evaluate the clinical outcomes of this regimen and examined whether systemic inflammation-based indices predict prognosis in this setting. We reviewed 52 consecutive patients with locally advanced NSCLC treated with first-line CCRT using daily low-dose carboplatin at three Japanese institutions between April 2007 and December 2019. The median progression-free survival (PFS) and overall survival (OS) were 11.5 and 40.1 months, respectively. Twenty patients received durvalumab as consolidation therapy. In the overall cohort, multivariate analysis identified the Glasgow Prognostic Score (GPS) as an independent predictor of PFS. A GPS of 0-1 was also associated with a significantly longer OS in univariate analysis. CCRT with daily low-dose carboplatin provided durable disease control with acceptable toxicity in older patients with unresectable stage II/III NSCLC. The GPS appears to be a simple marker for PFS in this population and may aid in pretreatment risk stratification alongside histology and consolidation strategies.
