. Kiilgaard Ruthenium-106 (Ru-106) brachytherapy is an established modality for eye-preserving treatment of choroidal melanoma. To achieve optimal treatment outcomes, there should be a balance between tumour control and the risk of healthy tissue toxicity. In this retrospective study, we examined normal tissue complication probability (NTCP) for visual acuity deterioration and late complications to aid the understanding of dose-dependence after Ru-106 treatments. We considered consecutive patients diagnosed with choroidal melanoma and primarily treated at a single institution from 2005–2014. Treatment plans w...

Conclusion: Primary PDT resulted in complete tumor regression of small amelanotic choroidal melanoma in 67% at mean 5 years, with no major effect on visual acuity.

CONCLUSION: Our study supports the finding that UM in Chinese and Asian-Indian patients presents at a younger age than in Caucasians. Although rare, ophthalmologists should remain mindful of this life-threatening disease. We propose a national and regional registry for ocular tumours with genetic information to characterise the disease spectrum in Southeast Asia. PMID: 31197380 [PubMed - as supplied by publisher]

Conclusion: Loading the choroidal tumor volume with GNPs improves the dose distribution by increasing dose to the tumor and decreasing dose to the health components in ocular brachytherapy with 125I seeds 20-mm COMS plaque.

Purpose: To study the relationship between gene expression profile subclass and clinical features in a multicenter cohort of patients with uveal melanoma. Methods: A retrospective, multicenter study was undertaken with patients entered from nine major ocular oncology centers from across the United States. Eligible patients had uveal melanoma and underwent I-125 plaque brachytherapy with concurrent tumor biopsy with gene expression profile testing between January 1, 2010, and October 28, 2014. Data were collected regarding patient demographics, baseline tumor clinical features, and gene expression profile results. Stat...

To test the radiobiological impact of hypofractionated uveal melanoma brachytherapy (BT), we calculated a hypo-fractionated equivalent dose (HFED) to the tumor that equates to 85 Gy of I125 low dose rate (LDR) BT for cases with and without vitreous replacement (VR). Corresponding organs-at-risk doses (OARs) were estimated.

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 base...

Purpose of review Endoresection of intraocular tumors is a complicated procedure utilizing pars plana vitrectomy techniques. Though it has potential downsides and complications, there is potential for this technique in the treatment of malignant and benign intraocular tumors. Recent findings Endoresection has been utilized in some form for the last three decades, but recent advances in vitreoretinal surgery have improved the technique. Endoresection is used most commonly to treat posterior uveal melanoma, but success in treating benign tumors, such as astrocytoma or retinal capillary hemangioblastoma has emboldened su...
