About this study
Neuroblastoma (NBL) is a type of cancer that occurs in nerve cells outside of the brain. Treatment for NBL is determined by certain risks factors including: The tumor stage, which is based on whether the tumor has stayed in one place or if it has spread to other parts of the body, the child’s age at diagnosis, and the biologic features of the tumor. Currently the standard therapy for non-high risk NBL or ganglioneuroblastoma includes surgery alone to remove the tumor or chemotherapy to make the tumor smaller followed by surgery. Although this approach results in excellent cure rates there is evidence that some of these patients may not need surgery or chemotherapy. This study enrolled participants less than one year of age who had a small mass (tumor) that was not involving other vital structures and was believed to be a non-high-risk neuroblastoma (NBL) or ganglioneuroblastoma or patients up to 18 months of age with tumors whose tumors had limited involvement of other vital structures or had spread to skin, liver or bone marrow (small amount). In this study, participants were enrolled in 1 of 3 groups; Group A, Group B, or Group C. Group assignment was based on the aforementioned risk factors. The overall goal for all participants in all groups in this study is to see if the doctors can treat non-high-risk NBL by either not doing surgery or by reducing the amount of chemotherapy given and still get very good results.
Objectives
- To eliminate therapy as the initial approach for infants less than twelve (12) months of age with small INRG Stage L1 neuroblastoma while maintaining an overall survival (OS) of ninety-nine (99) percent
- To eliminate therapy as the initial approach for non-high-risk patients less than eight-teen (18) months of age with localized neuroblastoma and favorable biology (histologic and genomic features) while maintaining an OS of ninety-nine (99) percent
- To achieve a three (3) year overall survival of greater than eighty-one (81) percent for infants less than eight-teen (18) months of age with INRG Stage Ms neuroblastoma using objective criteria for early initiation of a response-based treatment algorithm
