The State of Posttransplant Malignancies in Vascularized Composite Allotransplantation.
Article in Plastic and reconstructive surgery. Global open, 2026. 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: Vascularized composite allotransplantation (VCA) restores complex defects when conventional reconstruction is not feasible. However, lifelong immunosuppression introduces substantial risks, including posttransplant malignancies. This study aims to characterize the incidence, timing, management, and outcomes of posttransplant malignancies in VCA recipients to inform future surveillance and management guidelines. Methods: A systematic review was conducted according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) 2020 guidelines using PubMed, Scopus, Web of Science, and Cochrane. Eligible studies included patients who underwent VCA and developed a subsequent malignancy. Collected data included demographics, transplant and malignancy details, and survival. Results: Fifteen studies comprising 15 unique VCA recipients were included. Transplants involved the face (37.5%), upper extremity (37.5%), scalp (12.5%), lower extremity (6.25%), and abdominal wall (6.25%). Median time to first malignancy was 1.89 years posttransplant. Across all cases, 24 malignancies were reported, most commonly nonmelanoma skin cancer (60%) and posttransplant lymphoproliferative disorder (33%). Notably, 85% of skin cancers developed at nonallograft sites. Overall survival was 53.3%. All patients with skin cancer alone survived, whereas posttransplant lymphoproliferative disorder carried a 50% mortality rate. Median time from malignancy to death was 5.5 years, and from transplant to death, 10.1 years. Conclusions: Recipients of VCA demonstrate increased malignancy risk, particularly nonmelanoma skin cancers and lymphoma, with a typical onset of 2 years posttransplant. Dermatologic surveillance focusing on native skin, Epstein-Barr virus viral load monitoring in high-risk recipients, and regular follow-up are essential and may aid early detection.
