AIM: To compare the risk and pattern of High-Risk Pathologic Features (HRPF) in retinoblastoma between primary and secondary enucleation.
METHODS: A retrospective analysis of 121 eyes from 118 patients who underwent enucleation at the King Hussein Cancer Center (KHCC) Amman, Jordan, between November 2009 and January 2020. Demographic information, tumor stage, time from diagnosis-to-enucleation, results of pathology, metastasis, and mortality were retrieved.
RESULTS: Patients in the secondary group (49/121 eyes, 40%) were considerably younger at diagnosis (p = 0.0014), had bilateral disease (p = 0.0001), and had less-progressed disease at presentation (p = 0.016) compared to the primary enucleation. Primarily enucleated eyes were more-likely to have massive choroidal invasion (p = 0.0315) and post-laminar optic nerve invasion (p = 0.027), in spite of the finding that the overall prevalence of HRPF was similar between the two groups (35.5 percent vs. 37.5 percent; p = 0.585). The likelihood of anterior chamber invasion, was considerably higher in secondary enucleated eyes (p = 0.013). We evaluated primary and secondary enucleation for each subgroup (D and E) of the International Intraocular Retinoblastoma Classification (IIRC) and found the prevalence of HRPF was comparable (p = 0.58, 1.0, respectively). The difference in time between diagnosis-to-enucleation in secondary enucleation did not predict HRPF (p = 0.50). There was no discernible difference between primary and secondary enucleated eyes in terms of metastasis or survival (p = 0.156 and 0.44, respectively).
CONCLUSION: Systemic chemotherapy has the ability to reduce the extent of tumor expansion that has been pathologically identified. Primary and secondary enucleated eyes are comparable in low metastatic risk only when strict examination and management guidelines are followed.
