Oncological outcomes of selective axillary dissection with 4% carbon marking.

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
introductionThe use of axillary marking prior to Neoadjuvant Systemic Therapy (NST) is a controversial matter regarding patients with positive Lymph Nodes (LN). Several methods were tested to make possible the decrease of false negative rate in comparison to sentinel lymph node adding more accuracy to the results. This study aims to evaluate the oncological outcomes in patients who had undergone selective axillary dissection with 4% carbon marking before TSN.
methodsA prospective study was performed with cT1-T4, cN1-N2 breast cancer patients classified as suspected LNs undergoing concomitant 4% carbon marking. After TSN, targeted LNs were identified and resected associated to the sentinel lymph node (SLN) biopsy. The oncological outcomes pointed out were overall survival (OS), causespecific survival (CSS), distant disease-free survival (DDFS), axillary recurrence (AR) and local recurrence (LR).
resultsA total of 168 patients were evaluated for a median period of 49 months. The axillary emptying was reached in 89 (50.6%) cases. Five of 168 patients (2.9%) had axillary recurrence (AR). There was a significant link between axillary emptying and AR (0 vs. 6% p = 0.012). The DDFS was 140/168 (83.3%), OS 158/168 (94%) and CSS 158/163 (96.9%).
conclusionThe use of carbon marking in selective axillary dissection is a reliable low-cost method with simple execution. Among the oncological outcomes AR may not be considered for post downstaging axillary evaluation analysis since it is a rare event and not necessarily related to OS or DDFS.
