Sentinel lymph node detection for lung cancer surgery: a possible pathological surrogate of overall lymph node dissection.

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: Systematic lymph node dissection (SLND) is currently the gold standard for lung cancer surgery. However, this is not the case for breast cancer or melanoma, where sentinel lymph node (SLN) identification is routine. The SLN could be a possible surrogate for the pathological status of the other lymph nodes, but there is limited data in the literature for lung cancer surgery. The main objective of this study was to evaluate pathological concordance between the SLN and the complete lymphadenectomy. Methods: In this retrospective study, we reviewed all cases of localized lung cancer that had benefited from our SLN identification protocol and underwent surgery (segmentectomy or lobectomy) between December 2020 and December 2023. We examined the pathological status of the SLN and the rest of the lymph node dissection to assess the pathological concordance rate. Results: After exclusion, 106 patients with localized stage I-IIA non-small cell lung cancer and suspected node negative disease (N0) were included in our study. Of these 106 patients, 96 had a pN0 SLN (90.6%) and 10 had a positive SLN (pN+), resulting in an upstaging rate of 9.4%. All patients with a pN0 SLN were also pN0 for the rest of the lymph node dissection, corresponding to a pathological concordance rate of 100%. Disease-free survival was statistically lower in the pN+ SLN group than in the pN0 SLN group (p<0.0001). Conclusion: We demonstrated a 100% pathological concordance between SLN when it is cancer-free and the rest of the lymph nodes in the lymph node dissection, suggesting that the SLN is a good indicator of the overall pathological status of the other lymph nodes in the thorax.
