1 · What the graph read from it

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.

2 · The registry

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

backgroundThere is no consensus on the definition or recommended radiotherapy treatment of ultracentral non-small cell lung cancer (NSCLC). Here, we report our institution's experience in treating ultracentral lung cancer patients with stereotactic ablative radiotherapy (SABR) of 60 Gy in eight fractions.

methodsWe retrospectively reviewed the outcomes of 21 ultracentral NSCLC patients treated with 60 Gy SABR in eight fractions. We defined ultracentral lung cancer as the planning target volume (PTV) directly abutting or overlapping central structures, including the proximal bronchial tree, heart, and great vessels but not the esophagus. The Kaplan-Meier method was used to estimate overall survival (OS), progression-free survival (PFS) and local control (LC). Toxicity was scored per the CTCAE v4.03.

resultsThe median follow-up time was 15 months, and the median OS was 15 months. The one- and two-year OS rates were 87.5% and 76.6%, respectively. The one- and two-year PFS rates were 71.1% and 64.0%, respectively. The one- and two-year LC rates were 92.9% and 92.9%, respectively. The rate of grade 2 treatment-related toxicities was 19.1%. There was no grade ≥ 3 treatment-related toxicity.

conclusionSABR of 60 Gy in eight fractions is feasible for ultracentral NSCLC.
