Murine Model Study of a New Receptor-Targeted Tracer for Sentinel Lymph Node in Breast Cancer.
Article in Journal of breast cancer, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
purposeSentinel lymph node biopsy (SLNB), a critical staging and treatment step, has replaced axillary lymph node (LN) dissection as the standard staging procedure for early stage breast cancer patients with clinically negative axillary LNs. Hence, using a murine sentinel lymph node (SLN) model, we investigated the localization effect of the new receptor-targeted tracer, indocyanine green (ICG)-rituximab, on breast cancer SLNB.
methodsAfter establishing the murine SLN model, different doses of ICG-rituximab were subcutaneously injected into the hind insteps of BALB/c mice to determine the optimal dose and imaging time using continuous (> 3 hours) MDM-I fluorescence vasculature imaging. To explore the capacity of ICG-rituximab for sustained SLN localization with the optimal dose, MDM-I imaging was monitored at 6, 12, and 24 hours.
resultsThe popliteal LN was defined as the SLN for hindlimb lymphatic drainage, the iliac LN as the secondary, and the para-aortic or renal LN as the tertiary LNs. The SLN initial imaging and optimal imaging times were shortened with increased ICG-rituximab doses, and the imaging rates of the secondary and tertiary LNs increased accordingly. The optimal ICG dose was 0.12 μg, and its optimal imaging time was 34 minutes. After 24 hours, the SLN imaging rate remained 100%, while those of the secondary and the tertiary LNs increased from 0% (6 hours) and 0% (6 hours) to 10% (12 hours) and 10% (12 hours) to 20% (24 hours) and 10% (24 hours), respectively.
conclusionICG-rituximab localized to the SLN without imaging from the secondary or tertiary LNs within 6 hours. The optimal ICG dose was 0.12 μg, and the optimal interval for SLN detection was 34 minutes to 6 hours post-injection. This novel receptor-targeted tracer is of great value to clinical research and application.
