Abstract
Background: The aim of this study was to evaluate the significance of testing the gain of chromosome 8 and the gain of chromosome 6 as prognostic markers in histopathological samples of enucleated eyes in with uveal melanoma. Methods: This is a retrospective study of 54 enucleated eyes. The status of chromosomes 3, 8 and 6 was tested by CISH, and FISH was used in a few samples. A follow-up for the detection of metastases was conducted in all patients. The statistical significance of chromosomal abnormalities as a prognostic factor for the development of metastases was determined. Results: The study group consists of 54 patients (average age 63 years), 28 men (51.9%) Monosomy 3 together with gain of chromosome 8 was found in 10 samples (18.5%). Both chromosomal abnormalities were detected in 6 (11%) patients. No chromosomal abnormality in 3 or 8 was detected in 21 (38.9%) patients. Abnormalities of chromosome 6 were present in 6 (11%) patients. Progression free survival after 5 years was 33.3% (95% CI 0.0; 83.3) in these patients. Conclusions: Our findings indicate a correlation between progression-free survival and the presence of changes in chromosome 3 and e 8 in uveal melanomas. The results underline the necessity of testing for both chromosomal aberrations.
