Abstract

Purpose:

To study the clinical presentation, treatment, and outcome of patients with retinoblastoma (RB) in India.

Methods:

Retrospective study of 1,457 patients with RB (2,074 eyes).

Results:

The mean age at presentation of RB was 29 months (median, 24 months; range, <1–370 months). There were 812 (56%) men and 645 (44%) women with unilateral presentation of RB in 57% (n = 834) and bilateral in 43% (n = 623). Familial RB was present in 4% (n = 55). The most common presenting complaints included leukocoria (n = 1,100; 75%), proptosis (n = 91; 6%), strabismus (n = 77; 5%), and red eye (n = 68; 5%). Most (n = 1,889; 91%) tumors were intraocular in location, and 185 (n = 185; 9%) had extraocular tumor extension at presentation. The most common modalities of primary treatment–included systemic chemotherapy (n = 1,171; 60%) and enucleation (n = 674; 35%). At a mean follow-up period of 44 months (median, 30 months; range, 3–234 months), 92% (n = 1,206) were alive, and 108 (8%) patients died because of RB. Based on Kaplan–Meier analysis, the survival at 1, 3, 5, and 10 years was 94%, 91%, 90%, and 89%, respectively.

Conclusion:

The most common presenting signs of RB in Asian Indian population are leukocoria and proptosis. With appropriate treatment, the survival rate is favorable at 92%.
