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.

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.

Abstract

objectiveMultiple cohort studies have compared surgical resection with CT-guided percutaneous ablation for patients with stage 1 non-small cell lung cancer (NSCLC); however, the results have been heterogeneous. This systematic review and meta-analysis aims to compare surgery with ablation for stage 1 NSCLC.

methodA search of five databases was performed from inception to 5 July 2020. Studies were included if overall survival (OS), cancer-specific survival (CSS), and/or disease-free survival (DFS) were compared between patients treated with surgical resection versus ablation (radiofrequency ablation (RFA) or microwave ablation (MWA)) for stage 1 NSCLC. Pooled odds ratios (OR) were calculated.

resultsA total of eight studies were included (total 792 patients: 460 resection and 332 ablation). There were no significant differences in 1- to 5-year OS or CSS between surgery versus ablation. There were significantly better 1- and 2-year DFS for surgery over ablation (OR 2.22, 95% CI 1.14-4.34; OR 2.60, 95% CI 1.21-5.57 respectively), but not 3- to 5-year DFS. Subgroup analysis demonstrated no significant OS difference between lobectomy and MWA, but there were significantly better 1- and 2-year OS with sublobar resection (wedge resection or segmentectomy) versus RFA (OR 2.85, 95% CI 1.33-6.10; OR 4.54, 95% CI 2.51-8.21, respectively). In the two studies which only included patients with stage 1A NSCLC, pooled outcomes demonstrated no significant differences in 1- to 3-year OS or DFS between surgery versus ablation.

conclusionSurgical resection of stage 1 NSCLC remains the optimal choice. However, for non-surgical patients with stage 1A, ablation offers promising DFS, CSS, and OS. Future prospective randomized controlled trials are warranted. KEY POINTS: • Surgical resection of stage 1 NSCLC remains the optimal choice. • In patients with stage 1A NSCLC who are not surgical candidates, CT-guided microwave or radiofrequency ablation may be an alternative which offers promising disease-free survival and overall survival.
