Loco-regional relapse pattern and timing after segmentectomy in patients with c-IA non-small cell lung cancer.
Article in Journal of thoracic disease, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Background: Segmentectomy has been recognized as the standard procedure for small peripheral lung cancer; however, it has been shown that loco-regional relapse is more common with segmentectomy than with lobectomy. This study aims to investigate the long-term outcomes and loco-regional relapse patterns in patients with clinical stage IA (c-IA) non-small cell lung cancer (NSCLC) after segmentectomy and compare them with those after lobectomy. Methods: We retrospectively compared the long-term outcomes of 115 patients who underwent segmentectomy for c-IA NSCLC with those of 292 patients who underwent lobectomy between January 2008 and December 2015. Segmentectomy was indicated intentionally or chosen in patients who were considered intolerable to lobectomy. New isolated growing lung lesions were defined as relapses if they were not diagnosed with a second primary lung cancer. Results: The median observation period was 2,150 days. The 10-year overall survival (OS) rates and relapse-free survival (RFS) rates of the two groups were similar: 79.4% and 68.7% for segmentectomy, and 68.2% and 61.2% for lobectomy. Even after propensity score matching, no significant differences were observed in the OS and RFS rates between the groups. The segmentectomy group had a higher loco-regional relapse rate (14% Conclusions: Segmentectomy, both intentional and compromised, showed comparable long-term outcomes to lobectomy; however, loco-regional relapse can develop in a later phase than lobectomy, requiring careful follow-up.
