OBJECTIVE: To report the feasibility of intraoperative transscleral fine-needle aspiration biopsy at plaque surgery to obtain cells for monosomy 3 analysis in patients with choroidal melanoma. DESIGN: Consecutive interventional case series. PARTICIPANTS: Eighteen patients (18 eyes) with choroidal melanoma who had fine-needle aspiration biopsy performed with a 30-gauge needle at time of iodine 125 plaque placement. INTERVENTION: Cytology and cytogenetic analysis for monosomy 3 were obtained from biopsy specimens. MAIN OUTCOME MEASURES: Cytology, cytogenetic analysis for monosomy 3, and complications and feasibility of transscleral fine-needle aspiration biopsy of choroidal melanoma in vivo. RESULTS: Fine-needle aspiration biopsy was diagnostic of choroidal melanoma in 14 of 18 cases and resulted in viable cell cultures for fluorescent in situ hybridization (FISH) analysis in 9 cases. Fluorescent in situ hybridization for monosomy 3 was positive in 4 of the 9 cases. One patient had a mild vitreous hemorrhage. Tumors between 2 and 3 mm in height and those that yielded cells that did not attach in culture were most likely to have insufficient growth for FISH analysis. CONCLUSIONS: Transscleral fine-needle aspiration biopsy and FISH for monosomy 3 may provide important prognostic information on patients who undergo plaque radiotherapy for choroidal melanoma.
