Utility of a breast biopsy clip and a point marker system in tailored axillary surgery for patients with breast cancer after neoadjuvant chemotherapy.

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
backgroundTailored axillary surgery (TAS) is a new approach for selective removal of metastatic lymph nodes. This study evaluated the safety and utility of TAS using a breast biopsy clip inserted into a metastatic lymph node and a point marker consisting of a short hook wire and nylon thread to remove the clipped lymph node.
methodsPatients with breast cancer and clinically confirmed metastases to one-to-three axillary lymph nodes were included in this study. A breast biopsy clip was inserted into the metastatic lymph nodes before neoadjuvant chemotherapy. TAS was performed in patients with ycN0 disease after neoadjuvant chemotherapy. The lymph nodes containing the clips were removed using a point marker. The success criteria for TAS were the removal of the lymph node into which the clip was inserted using a point marker and the identification of the sentinel lymph node. The false-negative rate was calculated for cases in which TAS and axillary lymph node dissection were performed.
resultsThirty individuals from two institutions were enrolled between May 2021 and November 2022, of whom 20 underwent TAS. Ten patients had clinically positive axillary lymph nodes and underwent axillary lymph node dissection. No adverse events were observed in any patient using the clips or point markers. TAS was successful in 18 of the 20 patients (90%). Seven patients underwent TAS and axillary lymph node dissection with a false-negative rate of 0%.
conclusionThe use of clips and point markers to perform TAS is clinically feasible.
