Core Endoresection as Neoadjuvant Treatment of Uveal Melanoma.

AIM: To present a case of neoadjuvant treatment of uveal melanoma with a limited core endoresection, which enabled ruthenium plaque radiotherapy to be administered. MATERIAL AND METHODS: A 77-year-old woman presented in 2005 with a ciliochoroidal uveal melanoma measuring 7.2 by 6.5 mm basally with a thickness of 6.2 mm. The vision in the affected eye was 6/9. Because of diagnostic uncertainty, we performed a biopsy, which produced a copious sample. The biopsy serendipitously reduced the tumour thickness to 4.4 mm, making ruthenium plaque brachytherapy possible. RESULTS: Histopathological examination showed the tumour to be a melanoma predominantly of spindle cell type. Postoperative complications included a dense vitreous haemorrhage, which cleared spontaneously, and raised intraocular pressure, controlled with latanoprost. Seven years after brachytherapy, the vision was 6/5 and the thickness of the residual tumour was 2.5 mm. Nine years after treatment, there was no evidence of any intra- or extraocular seeding or distant metastases. CONCLUSIONS: Core endoresection of a ciliochoroidal melanoma may reduce tumour thickness enough to allow subsequent ruthenium plaque radiotherapy.
