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

backgroundStudies regarding the outcomes of salvage lung resections of epidermal growth factor receptor (EGFR)-mutant advanced lung adenocarcinomas (ALAs) following treatment with EGFR tyrosine kinase inhibitors (TKIs) are limited, hence the objective of this study was to investigate such outcomes.

methodsA total of 29 patients with EGFR-mutant ALA who underwent salvage surgery after EGFR-TKI treatment from October 2013 through January 2019 were enrolled. The patients were divided into two groups according to the surgical indications. Their perioperative parameters and surgical outcomes, including progression-free survival (PFS) and overall survival (OS), were then analyzed.

resultsThe initial stages of the patients were stage IIIB (seven patients), IVA (17 patients), and IVB (five patients). Their surgical indications included residual tumor (25 patients) and progressive disease (PD) (four patients). They all underwent surgery via minimally invasive approaches and the median follow-up was 33.9 months. Within that follow-up duration, the median PFS after surgery was 36.4 months, and the median OS was still not reached. There were no significant differences in PFS or OS according to the different EGFR-TKIs used, the different durations of EGFR-TKI treatment before surgery, or the different surgical indications. However, the patients presenting with pleural seeding before EGFR-TKI treatment had significantly poorer PFS and OS than the other patients (P < 0.001).

conclusionsSalvage surgery following EGFR-TKI treatment of ALAs is a safe procedure with acceptable intra- and postoperative results. However, studies involving more cases and longer follow-up periods are needed to clarify its benefits. KEY POINTS: Salvage surgery following EGFR-TKI treatment of ALAs is a safe procedure with acceptable intra- and postoperative results. Our results support the use of surgery following treatment with EGFR-TKIs such as afatinib in advanced lung cancer.
