Summary

This study details the successful treatment of bilateral retinoblastoma in a young girl using radiation, photocoagulation, and cryotherapy. Long-term follow-up showed tumor regression in both eyes, highlighting effective management of this childhood cancer.

Area of Science:

  • Ophthalmology
  • Pediatric Oncology
  • Radiation Oncology

Background:

  • Retinoblastoma is a rare childhood eye cancer, affecting 1 in 18,000-30,000 births.
  • Bilateral retinoblastoma cases present earlier and are often multifocal compared to unilateral cases.
  • Early diagnosis and treatment are crucial for managing retinoblastoma and preserving vision.

Purpose of the Study:

  • To report a case of bilateral retinoblastoma treated with external beam radiation and subsequent focal therapies.
  • To evaluate the long-term outcomes and regression patterns of treated bilateral retinoblastoma.
  • To illustrate the management of recurrent tumors in retinoblastoma.

Main Methods:

  • A ten-month-old female diagnosed with bilateral retinoblastoma (OD: Group Ia, OS: Group IIIb) received 3500 rads of external beam radiation.
  • Photocoagulation and cryotherapy were administered for new tumor development in the left eye (OS).
  • Metastatic workup was performed and found to be negative.

Main Results:

  • The patient achieved tumor regression in both eyes 15 years post-treatment.
  • The right eye (OD) showed Type II regression, while the left eye (OS) exhibited Type III regression.
  • No evidence of metastasis was detected.

Conclusions:

  • Combined modality treatment, including radiation and focal therapies, can achieve long-term tumor control in bilateral retinoblastoma.
  • Different regression patterns (Type II and Type III) were observed in the bilateral retinoblastoma case.
  • Multifocal and recurrent retinoblastoma necessitates tailored treatment strategies and vigilant follow-up.
