Retinoblastoma (RB) is the most common malignant eye tumor in children accounting for 10-15% of all cancer cases in infants. In spite of generally good standard treatment results there is still a subgroup of high-risk patients with by unfavorable prognosis, which warrants the search for additional treatment strategies. These children may benefit from treatment intensification in form of high-dose consolidation with subsequent autologous hemopoietic stem cell therapy (auto-HSCT). We here describe a case series illustrating N. N. Blokhin Cancer Center experience in this area.

Materials and methods

In 2021 a total of 3 children with high-risk RB were treated in N. N. Blokhin Cancer Center receiving high-dose regimen consisting of carboplatin (total dose of 1250 mg/m2), etoposide (1750 mg/m2), and cyclophosphamide (6000 mg/m2) with subsequent auto-HSCT.

Results

All 3 patients engrafted in day +11, +14, and +17 after auto-HSCT. The early post-transplant period was complicated by oral mucositis, neutropenic enterocolitis, and febrile neutropenia. One patient had a single episode of seizures due to hyponatremia. With a median follow-up of 6 (4-10) months two patients are alive and disease-free, one died due to disease progression.

Conclusions

The high-dose consolidation with subsequent auto- HSCT is a feasible option for high-risk RB patients. It is characterized by acceptable toxicity and is a potentially effective for disease control. In order to further evaluate the long-term results, there is a need for a larger prospective patient cohort. The multicenter study design may be beneficial in these settings.
