Three-dimensional ultrasound for the measurement of choroidal melanomas.
OBJECTIVE To evaluate the reliability of 3-dimensional ultrasound (3D-US) for the measurement of choroidal melanomas. DESIGN Retrospective case series. PARTICIPANTS Forty-two consecutive cases of choroidal melanoma imaged with 3D-US. METHODS Tumor measurements obtained with ophthalmoscopy, transillumination, standard ultrasound techniques, 3D-US, and pathological studies. Tumor diameters,...
متن کاملOutcomes of medium choroidal melanomas treated with ruthenium brachytherapy guided by three-dimensional pretreatment modeling.
PURPOSE The Collaborative Ocular Melanoma Study (COMS) established iodine-125 (I-125) plaque brachytherapy for eye preserving treatment of medium-sized choroidal melanomas in the United States. Eye Physics I-125 plaque treatment modeled with Plaque Simulator (PS) software yields similar results to COMS. Herein, we report results from a series of 15 patients treated with ruthenium-106 (Ru-106) p...
متن کاملChanges in height of choroidal melanomas after plaque therapy.
Serial ultrasonic measurements of 82 uveal melanomas treated with brachytherapy plaques (cobalt-60 and iodine-125) and followed up for up to 141 months revealed that no two patients had identical patterns of change. The mean absolute change in tumour height after treatment was 1.8 mm at six months, 5.6 mm at 48 months for large tumours, and 0.9 and 1.9 mm for medium sized tumours. Eighty of the...
متن کاملAnalysis of Bcl-2 protein expression in choroidal melanomas.
BACKGROUND Bcl-2 protooncogene alterations are involved in tumorigenesis and may have prognostic ramifications. AIMS To investigate normal ocular structures and choroidal melanoma for: (1) Bcl-2 protein expression (semiquantitative staining values: SI, staining intensity; PP, percentage of positive cells; and IRS, immunoreactivity score) and (2) any associations between the staining values an...
متن کاملImmunohistochemical demonstration of metallothionein in eyes with choroidal melanomas.
PURPOSE The since immunohistochemically detectable metallothionein (MT) overexpression has been described in a variety of human tumours, including skin melanomas, in relation to different stages of tumour development and progression. MATERIALS AND METHODS We used a monoclonal antibody to investigate the distribution of MT in 18 formalin-fixed, paraffin-embedded, surgically enucleated eyes wit...
