Uveal Melanoma: Refusal of Treatment.

Purpose: This study aimed to explore factors for refusing treatment in patients diagnosed with uveal melanoma and their subsequent clinical course.

Methods: This study included patients with uveal melanoma who refused standard of care treatment. Patient-reported reasons and pre-existing mental health diagnoses were assessed. The sociodemographic profile was compared with the controls. Ocular survival, metastasis-free survival (MFS), and overall survival (OS) were calculated.

Results: Nine patients with uveal melanoma declined ocular treatment (plaque brachytherapy, n = 7 [78%]; enucleation, n = 2 [22%]). The choroidal melanomas were small (n = 1 [11%]), medium (n = 5 [56%]), and large (n = 3 [33%]) in size (COMS criteria). The sociodemographic profile of the study patients was not different from those that accepted treatment. One patient (11%) had pre-existing mental health diagnosis. Five patients (56%) eventually accepted treatment following an average delay of 19 months (range: 4-55 months) due to neovascular glaucoma or severe vision loss. MFS could not be ascertained, and OS was 67% (6/9) at 4.2 years of follow-up (mean).

Conclusions: Refusal of initial recommended treatment is associated with poor ocular survival. The small sample size did not allow for an evaluation of the impact on survival.
