Comprehensive molecular analysis and MTB discussion revealed several potential treatment targets, leading to subsequent treatment including dinutuximab beta, nivolumab, cabozantinib, I-131-mIBG radionuclide therapy and alpelisib, unfortunately, all followed by disease progression. This case demonstrates the potential of comprehensive molecular analysis including methylation profiling for diagnosis and treatment guidance in rare tumors. Additional research is urgently required to improve outcomes in elderly patients with neuroblastoma.
The incorporation of dinutuximab beta into a modified N7 induction regimen demonstrates a satisfactory EOI response rate and a manageable safety profile in children with HR-NB. These preliminary results support the feasibility of this chemoimmunotherapy approach and warrant further investigation in larger cohorts to confirm its efficacy in long-term survival outcomes.
Real-world evidence on dinutuximab beta for high-risk neuroblastoma (NB) in the Chinese pediatric patients remains limited. Patients treated with prior ASCT or combined with chemotherapy showed trends toward improved response rates and survival outcomes, although optimal treatment regimens required further investigation. AEs are generally manageable, and the use of standardized pain assessment combined with multimodal analgesia has enabled a substantial reduction in morphine exposure.
All sensitivity unadjusted and adjusted comparisons supported the results of the base-case analysis. Dinutuximab beta significantly prolonged OS compared to historical control cohorts not treated with dB in both unadjusted and adjusted indirect comparisons.
