Application of ultrasound-guided placement of markers for locating axillary lymph nodes of breast cancer.

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
backgroundWith the continuous improvement of pathological complete response (pCR) rate after neoadjuvant therapy (NAT), it is necessary to locate the tumor bed and axillary lymph nodes (ALNs) for subsequent surgery. Therefore, breast tissue markers emerge. This study aims to evaluate the feasibility and accuracy of ultrasound (US)-guided placement of markers for locating ALNs of breast cancer.
methodsA total of 285 patients who received US-guided placement of markers for locating ALNs in our hospital were selected. Among these patients, 87 patients were in the early breast cancer (EBC) group with negative ALNs and 198 ones were in the NAT group with positive ALNs. Data including the basic information of patients, position and size of ALN, process of US-guided marker placement, placement success rate, complications, detection rate of marker by imaging, and shift rate were recorded.
resultsAll patients were successfully undergone US-guided marker placement. And the average operation time was 2 minutes with no adverse reactions. All the patients underwent surgery successfully. US, computer tomography (CT) and magnetic resonance imaging (MRI) were used to detect the marker. The detection rate of markers by US and CT/MRI were 100% (87/87) in EBC group, and 98.5% (195/198) and 100% (198/198) by US and CT/MRI, respectively, in NAT group. The postoperative marker shift rate was 2.1% (6/285), including 3.4% (3/87) marker shift rate in EBC group and 1.5% (3/198) in NAT group, with no statistically significant difference between them.
conclusionsUS-guided marker placement in ALNs of breast cancer is simple and safe, with firm positioning and low shift rate, which is convenient for clinical promotion.
