Correlation between the drainage time in dynamic indocyanine green lymphography (ICG) and axillary lymph nodes metastatic involvement in breast cancer patients-a prospective study.

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
purposeAxillary lymph nodes dissection (ALND) carries several complications, prompting the search for less invasive methods, especially after neoadjuvant chemotherapy. This study investigated the correlation between dynamic indocyanine green (ICG) lymphography drainage time of the upper limb and the pathological stage of axillary metastatic involvement. We hypothesized that prolonged ICG drainage time correlates with higher nodal burden.
methods45 female breast cancer patients undergoing ALND were enrolled. Dynamic ICG lymphography was performed the day before surgery, with intradermal injections in both upper limbs. ICG drainage time to the axillary region was recorded. Pathological and clinical lymph nodes stages (cN/(y)pN) were determined. Statistical analyses included ANOVA, t-tests, and ROC analysis were performed.
resultsThe mean ICG drainage time was 625.6 ± 199.0 s. A statistically significant correlation was found between ICG drainage time and (y)pN stage (p < 0.05). Patients were categorized into low-burden ((y)pN0 + (y)pN1)-33 patients, and high-burden ((y)pN2 + (y)pN3) group-12 patients. Drainage time was significantly delayed in the high-burden group (525.8 ± 103.3 s vs. 900.1 ± 134.3 s; p < 0.001). No significant difference was observed between (y)pN0 and (y)pN1. ROC analysis demonstrated a high discriminatory ability for differentiating between low and high nodal burden (AUC 0.995), with an optimal cut-off of 695 s. No correlation was found with time of drainage and cN, tumor biological features, age, BMI, or arm circumference.
conclusionDynamic ICG lymphography drainage time correlates with pathological axillary nodal metastatic burden in breast cancer patients, particularly differentiating between low and high nodal involvement. This non-invasive functional assessment holds promise as a valuable adjunct for precise axillary management, guiding surgical de-escalation strategies, and potentially identifying patients at higher risk for lymphedema.
