Abstract:
Retinoblastoma usually recurs within the first few years after treatment completion. We report a rare case of very late relapse in a 6-month-old girl who was diagnosed with bilateral retinoblastoma. The patient achieved first remission after treatment with neoadjuvant chemotherapy, enucleation of the right eye, local laser therapy of the left eye, and adjuvant chemotherapy. Extraocular relapse with multiple metastases occurred 13 years and 8 months after treatment. The patient is currently in second complete remission after receiving high-dose chemotherapy and autologous stem cell transplantation. In conclusion, long-term follow-up is needed for early detection of recurrent retinoblastoma.
