Objective: To analyze the clinical characteristics and therapeutic effect of 46 patients with bilateral retinoblastoma(RB). Methods: The clinical data of 46 patients with bilateral retinoblastoma who received intravenous chemotherapy combined with transpupillary thermotherapy (TTT) or enucleation from December 2008 to December 2019 in our department were analyzed retrospectively. The eye salvage rate, enucleation rate, visual acuity, and chemotherapy side effects were evaluated. Results: The 46 enrolled patients were 27 males and 19 females, at an average age of (13.21±11.13) months at the first visit. Among them, 10 received chemotherapy, 11 received chemotherapy combined with TTT, 17 received chemotherapy combined with TTT and enucleation,and 2 received chemotherapy combined with freezing, 6 received chemotherapy combined with freezing and enucleation. After treatment, 58 eyes were salvaged, with a total salvage rate of 73.1% (57/78), and the eyes that preserved vision account for 64.1% (50/78). The eye salvage rate in each stage were 100.0% for stage A and B, 86.7% for stage C, and 94.1% for stage D, 35.7% for stage E. Twenty-four eyes were enucleated, with a total enucleation rate of 26.1% (24/92), and among 35 eyes at stage E, 21 eyes were enucleated, accounting for 60.0%(21/35). The average time of chemotherapy was 4.1±1.9 and the myelosuppressive effects of chemotherapy include leucopenia, thrombocytopenia and hemoglobinopenia. During the mean follow-up time of (35.4±23.8) months, 7 (15.2%) patients died, and 39 (84.8%) cases survived. The 5-year cumulative survival rate was 80.2%. Conclusion: Intravenous chemotherapy combined with local treatment has a good overall effect and plays an important role in the treatment of bilateral retinoblastoma. Intravenous chemotherapy leads to myelosuppression, and the myelosuppression gradually recovered after stopping intravenous chemotherapy.
