Factors Influencing Fluorescence-activated Cell Sorting for Multiple Myeloma Fluorescence
Article in Annals of laboratory medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: FISH is the standard method for detecting cytogenetic abnormalities (CAs) in patients with multiple myeloma, and pre-enrichment of plasma cells is recommended to increase detection rates. However, optimal strategies to ensure sufficient plasma cell retrieval when standard enrichment techniques fail remain underexplored. We investigated factors influencing the success of fluorescence-activated cell sorting (FACS) and assessed the use of direct FISH in cases in which FACS failed. Methods: A retrospective analysis was conducted on 457 bone marrow samples submitted for FISH between November 2016 and May 2022. FACS was considered successful when plasma cells (CD38+ and CD138+ cells) constituted >1% of the total number of cells. Direct FISH was performed for samples with FACS failure. Results: FACS was successful in 70.9% of cases and had a high positivity rate (94.8%). Shorter sample transfer times significantly improved FACS success, with a 77.1% success rate for transfer times <2 hrs, compared with 67.8% for longer times ( Conclusions: Plasma cell percentage and sample transfer time are critical factors influencing FACS success. While FACS-FISH demonstrates superior sensitivity in detecting CAs, direct FISH serves as a valuable alternative when FACS fails. These findings highlight the importance of optimizing sample handling and FISH protocols for accurate cytogenetic analysis of multiple myeloma.
