Sandwich Therapy with Radionuclide Combined with Intralesional Injections Based on Differences in the Spatial Structure Components of Keloids.
Article in Aesthetic plastic surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundComplications such as ulceration, depigmentation, and recurrence limit the use of intralesional injections and brachytherapy in keloid treatment. We designed a modified "sandwich" therapy based on the spatial distribution of keloid components to reduce the incidence of these complications.
methodsFirst, we analyzed the spatial distribution pattern of scar tissue through single-cell sequencing analysis, ultrasound, and pathology. Subsequently, a "sandwich" therapy combining radionuclide and intralesional injections was designed based on the pattern found in the previous stage. Finally, 40 patients with keloid scars at 41 sites were included in the clinical trial.
resultsSingle-cell sequencing identified two significant cellularly highly expressed genes and enriched pathways in the keloid vascular wall that primarily play essential roles in angiogenesis and promoting collagen synthesis, thereby promoting scar growth. Color ultrasound showed that there were hierarchical differences in the blood supply of the keloid, and further H&E, CD34, and eNOS staining showed that there were hierarchical differences in the spatial structure of blood vessels, fibroblasts, and collagen in the keloid. In clinical studies, the complication rate of "sandwich" therapy is lower than that of conventional treatment.
conclusionThe distribution of blood vessels and collagen in keloid scars is characterized by spatial variability. The "sandwich" therapy of radionuclide combined with intralesional injections is a modified type of precisely targeted therapy designed based on this variability; it has fewer complications and good clinical efficacy and is worthy of popularization.
