Abstract

Objective: To study the impact of the retinoblastoma growth pattern (endophytic vs. exophytic) on the clinical and pathological features after primary enucleation. Material and Method: A retrospective case series of 42 eyes of 41 patients who had pathologically confirmed retinoblastoma. The main outcome measures included demographics, laterality, international intraocular retinoblastoma (IIRC) group, vitreous seeding, neovascular glaucoma, choroid invasion, optic nerve invasion, metastasis, and survival. Results: The median age at diagnosis was 30 months. Nineteen (46%) patients were males, and 17(41%) patients had bilateral retinoblastomas. Eight (19%) eyes were IIRC group C, 20 (48%) eyes were IIRC group D, and 14 (33%) eyes were IIRC group E. Nineteen (45%) tumors were endophytic, 14 (33%) were exophytic, and 9 (21%) were mixed. Choroid invasion was seen in 4 (21%) of the endophytic tumors, 5 (36%) of the exophytic tumors, and 8 (89%) of the mixed tumors (p=0.025). A mixed growth pattern was associated with massive choroid invasion in 5 (56%) of eyes. Neovascular glaucoma was seen in 5 (56%) of the mixed tumors (p=0.0376). Vitreous seeds were seen in 6 (67%) of the mixed tumors (p=0.0448). Optic nerve invasion as well as patients age at diagnosis, gender, and tumor laterality had no correlation with tumor growth pattern. At a median follow up of 36 months, no single case had metastasis or was dead. Conclusion: Exophytic tumors have higher risk of choroid invasion, while endophytic tumors have higher risk of vitreous seeding. The mixed tumor growth pattern is associated with more advanced IIRC group, more risk of neovascular glaucoma, and more risk of massive choroid invasion.

Özet

Amaç: Primer enükleasyon sonrası retinoblastomanın büyüme paternlerinin (endofitik, ekzofitik ve karışık) klinik ve patolojik özelliklere etkisini araştırmak. Gereç ve Yöntem: Retinoblastoması patolojik olarak onaylanmış 41 hastaya ait 42 gözden oluşan retrospektif olgu serisi. Dahil edilen ana ölçümler: Demografik bilgiler, lateralite, uluslararası intraoküler retinoblastoma grubu (UİRG/IIRC) sınıfandırması, vitröz yayılım, neovasküler glokom, koroid invazyonu, optik sinir invazyonu, metastaz ve yaşam süresi. Bulgular: Tanı anında medyan yaş 30 ay idi. Ondokuz (%46) hasta erkekti ve 17 (%41) hasta bilateral retinoblastomalıydı. Sekiz (%19) göz IIRC grup C, 20 (%48) göz IIRC grup D ve 14 göz IIRC grup E idi. Ondokuz (%45) tümör endofitik, 14 (%33) ekzofitik ve 9 (%21) karışıktır. Koroid inazyonu endofitik tümörlerin 4 (%21)ünde, ekzofitik tümörlerin 5 (%36)inde ve karışık tümörlerin 8 (%89)inde görülmüştür (p=0,025). Karışık büyüme paterni gözlerin beşinde (%56) massif koroid invazyonu ile ilişkilidir. Neovasküler glokom karışık paternli tümörlerin 5 (%56)inde görülmüştür (p=0,0376). Vitröz yayılım karışık tümörlerin 6 (%67)sında görülmüştür (p=0,0448). Optik sinir invazyonu yanı sıra tanı anında yaş, cinsiyet ve tümör lateralitesi tümör büyüme paterni ile ilişkili değildir. Medyan 36 aylık takipte hiç bir olguda ölüm veya metastaz görülmemiştir. Sonuç: Ekzofitik tümörlerin daha fazla koroid invazyon riski, endofi- tik tümörlerin ise daha fazla vitröz yayılım riski vardır. Karışık büyü- me paterni daha ileri IIRC grubu, daha fazla neovasküler glokom ve massif koroid invazyonu ile ilişkilidir.
