- Patients must have either (1) a diagnosis of NB as defined by international
criteria,84 i.e., histopathology (confirmed by the MSKCC Department of Pathology) or
BM metastases plus high urine catecholamine levels, or (2) a tumor that is
o A non-NB tumor is defined as GD2-positive by immunostaining with m3F8. If fresh or
frozen tumor is not available for immunostaining, patients will be considered
eligible if published reports show that >50% of that tumor type is GD2-positive by
immunohistochemistry. (Note: Tissues must be fresh/frozen as fixed, paraffin-embedded
specimens are unsuitable for anti-GD2 immunostaining). Tumors known to be GD2-
positive by this criteria do not need immunostaining. These include: Melanoma (>50%),
Desmoplastic small round cell tumors (70%), Osteosarcoma (88%) and Soft tissue
sarcomas including liposarcoma, fibrosarcoma, malignant fibrous histiocytoma,
leiomyosarcoma, and spindle cell sarcoma (93%).
- Patients must have either (1) refractory or relapsed high-risk NB (including
MYCN-amplified stage 2/3/4/4S of any age and MYCN-nonamplified stage 4 in patients
greater than 18 months of age)resistant to standard therapy*, or (2) refractory or
relapsed GD2-positive tumor after receiving available life-prolonging therapies.
*For NB, standard therapy generally includes 5-8 cycles of high dose induction
chemotherapy followed by resection of gross residual tumor, with or without
myeloablative chemotherapy with peripheral blood stem cell rescue and radiation
therapy to the primary site. There are also salvage chemotherapy regimens for
residual disease after standard induction therapy or for relapsed NB. Some examples
of these chemotherapy combinations are: high-dose cyclophosphamide, topotecan and
vincristine; high-dose cyclophosphamide, irinotecan and vincristine; irinotecan and
temozolomide; or ifosfamide, carboplatin and etoposide.
- Patients must be older than 1 year of age.
