PURPOSE: To compare the outcomes of combined treatment of choroidal melanoma with ruthenium brachytherapy (BT) simultaneously with transpupillary thermotherapy (TTT) and treatment with BT alone. METHODS AND MATERIALS: Two matched groups of patients, one treated with BT and simultaneous, TTT (Group BT + TTT, n = 63), the other treated with BT alone (Group BT, = 70) were analyzed retrospectively. The main outcome measures were rate of tumor regression, recurrences, enucleations, metastases, recurrence-free and overall survival rate, and visual acuity, assessed by Kaplan-Meier analysis. RESULTS: Patients were matched according to mean age (p = 0.22), mean tumor thickness (6.4 vs. 6.25 mm, range 2.5-10.8 mm, p = 0.59), and mean length of followup (42 vs. 34.4 months, range 3-109, p = 0.052). Tumor largest basal diameter (13.0 vs. 12.9 mm), tumor location, and mean radiation dose (apical 135 vs. 136 Gy and scleral 1294 vs. 1438 Gy) were also similar in both groups (p > 0.1). Treatment with BT + TTT resulted in higher rate of tumor regression (63% vs. 49%, respectively, p = 0.036), lower 5-year tumor recurrence rate (96% vs. 83%, p < 0.034), and higher eye-globe preservation (98% vs. 87%, p < 0.024) and recurrence-free survival rates (89% vs. 67%, p < 0.017) than treatment with BT alone. There was no difference in complications (p > 0.5), metastasis-free (93% vs. 81%, p > 0.22) and overall survival rates (91% vs. 81%, p > 0.39), or in visual outcomes. CONCLUSION: Combined treatment of choroidal melanoma with ruthenium BT and simultaneous TTT seems to provide higher local control, eye-globe preservation, and recurrence-free survival rates than treatment with BT alone and results in similar rates of metastases and overall survival.
