Abstract
BACKGROUND: In several malignancies, gender-based survival differences after specific therapeutic interventions have been demonstrated. It is not known whether such differences exist after plaque brachytherapy of uveal melanoma. METHODS: All patients who received brachytherapy for uveal melanoma at St. Erik Eye Hospital from November 1, 1979 through November 20, 2017 were included (n = 1,541). Retrospective data were retrieved including baseline patient and tumor characteristics, brachytherapy nuclide (ruthenium-106 or iodine-125), radiation dose, treatment duration, tumor relapses, date of metastasis, and cause of death. RESULTS: A total of 775 men and 766 women were treated with plaque brachytherapy. There were no significant differences between the genders in baseline characteristics, treatment, or follow-up. Men and women had similar rates of tumor relapses, hazard for repeated brachytherapy (men vs. women 0.8, p = 0.47), enucleation-free survival, and survival after detection of metastasis. Five-, 10-, and 15-year melanoma-related mortality was 14, 24, and 27% for men and 15, 26, and 32% for women, respectively. There were no significant differences in hazard for melanoma-related mortality (men vs. women 0.9, p = 0.32), median Kaplan-Meier disease-specific survival (men 18.2 years, women 15.5 years, p = 0.22), or median overall survival (men 13.5 years, women 12.6 years, p = 0.60). CONCLUSION: There are no relevant differences between men and women in ocular or patient survival after brachytherapy for uveal melanoma.
