Treatment of small and medium retinoblastoma tumors with Iris diode laser

Research output: Contribution to journalArticlepeer-review

Abstract

Purpose: Differing techniques have been reported for focal laser therapy for patients with small and medium retinoblastoma. We report the technique used at our center; and report the functional and anatomical outcomes for small and medium retinoblastomas treated with focal laser therapy with or without systemic chemotherapy. Methods: A retrospective case study was conducted including pediatric patients with macular retinoblastoma treated with systemic chemotherapy and laser ablation from July 1990 to July 2015 at Washington University School of Medicine/Saint Louis Children’s Hospital. Results: Fourteen eyes (11 patients) with small and medium retinoblastoma tumors were treated with repetitive indirect laser hyperthermia and seven of those patients were treated with systemic chemotherapy as well. Using the International Retinoblastoma classification, one eye was stage A, 10 eyes were stage B, and three eyes were stage C. The mean follow-up time was 7.7 years. There were no recurrences of tumor in the patients. Final visual acuity outcomes were 20/20 to 20/50 in four eyes, 20/60 to 20/200 in four eyes, and 20/400 or less in six eyes. None of the patients developed metastatic disease. Conclusions: The evidence for systemic chemotherapy and diode laser therapy is limited to case series and retrospective reviews, but evidence suggests that it is an effective treatment for small and medium sized retinoblastoma tumors involving the macula with the potential for good visual outcomes.
