Endoresection in Choroidal Melanoma: Outcomes of Intentional Incomplete Tumor Removal.
Observational study in Current oncology (Toronto, Ont.), 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
To assess the outcomes of a modified surgical approach for the treatment of uveal melanoma involving endoresection with intentional residual tumor at the margins, combined with adjuvant ruthenium-106 brachytherapy. This technique aims to reduce surgical morbidity, while preserving visual function and maintaining effective local tumor control and survival. We conducted a retrospective observational study including 33 patients with choroidal melanoma treated between January 2017 and August 2024 at a single tertiary ocular oncology center in Spain. Patients underwent pars plana vitrectomy and endoresection leaving residual tumor followed by ruthenium-106 brachytherapy. Clinical, functional, and oncological outcomes were analyzed, including tumor recurrence, metastasis, visual acuity, complications, and cytogenetic findings. Kaplan-Meier analysis was used to estimate survival and recurrence rates. After a mean follow-up of 41.7 months, local tumor recurrence occurred in 2 patients (6.06%) and enucleation was performed in 1 patient (3.03%). Two patients (6.06%) developed metastases, with one disease-specific death, resulting in a 5-year survival rate of 97%. Visual acuity of 20/200 or better was preserved in 60.61% of patients. The most frequent complications were retinal detachment (36.36%) and macular edema (45.45%). Cytogenetic analysis showed a significant association between chromosome 1p loss and both recurrence and metastasis (
