Eligibility
Inclusion criteria
Inclusion criteria: 1. Age 1 to 18 years. 2. Diagnosis of high-risk neuroblastoma according to the International Neuroblastoma Risk Group (INRG) criteria. 3. Primary refractory disease is defined as failure to achieve complete remission or very good partial remission after standard induction therapy (4-6 cycles of chemotherapy plus surgery), including stable disease (SD), minor response (MR), and partial remission (PR). 4. Measurable active lesions are defined as: <= 3 lesions with a diameter of <= 3 cm in bone/bone marrow and/or 1 lesion with a diameter of <= 1.5 cm in soft tissue, as demonstrated by DOPA PET/CT examination. Active lesions are identified as anatomical sites with positive DOPA uptake; local MRI confirmation may be required. 5. Female patients of childbearing age must have a negative pregnancy test. Male and female patients of childbearing age must agree to use effective contraceptive measures during the treatment period and for 6 months after the treatment is discontinued. 6. Patients deemed by the investigator's clinical judgment to be suitable for treatment according to this study protocol. 7. A written informed consent must be signed by the legal guardian(s) of the pediatric patient. When the pediatric patient is capable of making the decision to participate in the clinical trial, both the pediatric patient and the legal guardian(s) must provide their consent on the form.
