Abstract

To evaluate the prognostic value of DNA content-ploidy, agoraphilic nucleolar organizing regions (AgNORs) and proliferating cell nuclear antigen (PCNA) for survival among patients with choroidal melanoma choroidal melanomas managed by enucleation in 55 patients with a follow-up of 5 years were studied. AgNor counts were evaluated by two examiners after sections were specifically processed. Immunohistochemistry was performed to evaluate PCNA expression. Kaplan-Meier estimation of survival curves, the log-rank test, and Cox regression analysis were used to compare survival according to the above mentioned factors. Five years after enucleation 62% of patients had died. Patients with spindle cell type melanomas had the best and those with epithelioid cell type had the worst survival (p=0.004). Patients with small tumors had better survival than those with medium or large tumors (p=0.02). Patients having tumors with aneuploid nuclear DNA content had worse survival than those having tumors with diploid DNA content (p=0.004). A high PCNA level correlated with lower survival rates (p=0.02). Patients having a high AgNor count had a worse survival than those with lower counts (p=0.02). DNA content, PCNA level, and AgNOR count each showed a clinically significant influence on patient survival. However, each of these new evaluated prognostic factors was strongly related to one or both of the classic prognostic factors. It is therefore difficult to separate the effects of the two categories of prognostic factors. Results of the Cox regression analysis suggested that these newer evaluated prognostic factors provided little additional information about patient prognosis.
