Regression rate of choroidal melanoma following iodine-125 brachytherapy is not associated with metastatic spread
Nearly half of choroidal melanomas progress to the metastatic stage at 15 years. The purpose of our study was to evaluate the prognostic value of tumour-height regression rate in medium-sized choroidal melanomas treated with iodine-125 brachytherapy. A retrospective cohort study was performed on 128 patients with medium-sized choroidal melanoma who were treated with iodine-125 brachytherapy. Tumour characteristics including tumour apical height at baseline and after irradiation, recurrence, metastasis and mortality were collected from patients’ records. Regression rate was defined in mm/month or in percentage of baseline apical height. Patients were statistically stratified in three groups of regression rate at 6 months using the Ward’s method and Euclidian distance (slow, medium and fast regression groups). Mean initial apical height was of 5.71±1.79 mm. At 6 months, the average regression rate was 0.02±0.12 mm/month in the slow group (n=60), 0.32±0.11 mm/month in the medium group (n=52) and 0.67±0.21 mm/month in the fast group (n=16). Cox regression analysis for the recurrence, metastasis and mortality rates according to the three groups did not show any statistically significant difference. Sensitivity analyses with the regression rates at 12 months showed similar associations. Exudative retinal detachment resolved with treatment at 5.9±4.0 months, and it was more common at presentation in the fast ...

CONCLUSION: Hypofractionated stereotactic photon radiotherapy showed a high rate of local tumor control for choroidal melanoma and an acceptable rate of radiogenic side effects. PMID: 32969745 [PubMed - as supplied by publisher]
Inflammatory, angiogenic, and immune processes have been associated with uveal melanoma (UM). The aim of the present study was to evaluate the presence of some specific aqueous humor (AH) soluble biomarkers in eyes affected by UM. Thirty-five eyes affected by primary UM and 35 control eyes, scheduled for cataract surgery, underwent full ophthalmic examination and AH sampling at time of surgery (brachytherapy or cataract surgery, respectively). AH samples were analyzed by means of ELISA, to detect the concentration of selected cytokines, chemokines, and growth factors. Compared with the control group, higher levels of IL-6 ...
Conclusions: The results of this review suggest that there are no important differences in OS when comparing the different current treatment modalities. Most of the differences found seem to be explained by the heterogenicity of the different studies and the presence of biases in their design, rather than actual extensions of patient survival.
Abstract AIM: To assess the outcomes of small choroidal melanoma following iodine-125 episcleral brachytherapy (apical height dose of 85 Gy). METHODS: Patients with small choroidal melanoma that underwent iodine-125 episcleral brachytherapy between January 2004 and December 2017 were reviewed. Inclusion criterion for this study was the COMS small tumour size (tumour apical height of 1.0-2.5 mm and largest basal diameter (LBD)
To evaluate 106Ruthenium Brachytherapy in management of medium sized uveal melanoma, with emphasis on 5-year outcome and toxicity.
Conclusion: Although rare, the possibility of multiple uveal melanoma does exist. Examination of the treated and contralateral eye on a regular basis is crucial, not only to identify local failure but also new metastases from the primary tumor and additional primary tumors.Ocul Oncol Pathol
Abstract INTRODUCTION: Uveal melanoma is most commonly treated with radiotherapy, destroying the tumour cells with adequate safety margins and limiting collateral damage to surrounding structures to preserve maximal vision. We used optical coherence tomography (OCT) to study the effects of radiotherapy on the retina. METHODS: Patients with posteriorly located choroidal melanoma treated with proton beam radiotherapy (PBR) and ruthenium-106 brachytherapy between January 2010 and June 2014 underwent spectral domain OCT. RESULTS: Images of 32 patients following ruthenium-106 brachytherapy and 44 patients fol...
Conclusion: The vertical thickness of the thickest macular cyst, the presence of foveal retinal pigment epithelium atrophy, and IS/OS layer disruption can be used to clinically characterize radiation maculopathy. These parameters allow for separation of the edematous component of radiation maculopathy, which is potentially treatable in early disease stages, from late onset atrophic components, which are theoretically irreversible.
Uveal melanoma (UM) is the most common intraocular malignancy. The incidence of UM is 10 cases per million per year in New Zealand (twice the US incidence). Treatment options include enucleation, plaque brachytherapy and localised radiotherapy. Despite successful treatment of the primary tumour, metastasis occurs in up to half of all patients.
