Abstract

Background: Ocular abnormalities (OA) in pediatric patients with acute lymphoblastic leukemia (ALL) are common findings both at diagnosis and later in follow-up. The frequency, predictors, and prognostic impact of OA in the context of recent ALL protocols are not well characterized.

Procedure: Single-center retrospective analysis of the medical records of 224 patients with ALL enrolled on Dana-Farber Cancer Institute (DFCI) ALL Consortium Protocol 05-001.

Results: Overall, 217 (98%) patients had at least one ophthalmic exam. Retinal hemorrhages were the most frequent abnormalities at diagnosis (11%) and cataracts at later time points (13%). OA at diagnosis were associated with age ≥10 years and with the severity of anemia and thrombocytopenia; they were also univariately associated with lower 5-year event-free survival (EFS) (high risk [HR] = 3.09 [95% CI: 1.38-6.94]; p = .006), but not in a disease-free survival (DFS) model adjusted for end-induction minimal residual disease (p = .82). The cumulative incidence of cataract was 13.1% ± 2.8% at 43 months from diagnosis; its development was associated with high presenting white blood cell count (≥50,000/μl) (p = .010), male sex (p = .036), higher risk group (p = .025), and cranial radiation (p = .004). Cataract was associated with decreased visual acuity.

Conclusions: OA at diagnosis, present in 12% of patients, were associated with older age, anemia, and thrombocytopenia and did not carry a significant prognostic impact. Cataracts were detected in over 10% of patients and were associated with decreased visual acuity, thus supporting routine screening after completion of therapy, especially for those treated with high-risk protocols.

Keywords: ALL; cataracts; ocular abnormalities; visual acuity.
