Dissemination of Uveal Melanoma After Diagnostic Biopsy With 23-Gauge Vitrector.

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
purposeTo report a case with tumor dissemination after diagnostic choroidal biopsy.
methodsMultimodal imaging and histopathology correlation.
resultsA 64-year-old male presented with an atypical uveal mass and underwent a diagnostic transretinal 23-gauge vitrector biopsy to diagnose melanoma. Post-operative course was complicated by prolonged vitreous hemorrhage which required vitrectomy, delaying proton beam treatment by two months. One year after the biopsy, the tumor cells had disseminated to the retina, optic nerve, iris, iridocorneal angle, and extraocularly via the vitrectomy port. The patient died from metastatic melanoma one year later. To the best of our knowledge, there are 10 prior cases with biopsy-related tumor seeding in the literature, with risk features including multiple vitreous surgeries, a long interval between biopsy and treatment, and high-risk melanoma cytogenetics. Severe vitreous hemorrhage following biopsy further postpone treatments or warrant vitrectomy, both increasing the risk of tumor spread.
conclusionsBiopsy of choroidal melanoma, especially when complicated by severe vitreous hemorrhage, can lead to dissemination of the malignant tumor.
