Neuroblastoma stage IV-S
1Department of Pediatrics, University of Tennessee Medical Center, Knoxville 37950-0642, USA.
Insights
Stage IV-S neuroblastoma in infants can spontaneously regress due to its unique biology, though some cases are fatal. Prognostic factors like age and genetic markers help predict outcomes for neuroblastoma patients.
Area of Science:
- Pediatric Oncology
- Cancer Biology
- Genetics
Background:
- Stage IV-S neuroblastoma is a unique clinical presentation in infants.
- Understanding the factors influencing spontaneous regression versus fatal outcomes is crucial.
Purpose of the Study:
- To review prognostic features guiding treatment for stage IV-S neuroblastoma.
- To discuss the biological basis for spontaneous regression and fatal progression.
- To explore the influence of various biological markers on patient outcomes.
Main Methods:
- Review of existing literature on stage IV-S neuroblastoma.
- Analysis of clinical staging, age at diagnosis, and tumor biology.
- Discussion of genetic, molecular, immunological, and biochemical markers.
Main Results:
- Identified prognostic features that can guide treatment decisions.
- Discussed the biological mechanisms behind spontaneous tumor regression.
- Highlighted factors contributing to both favorable and unfavorable outcomes.
Conclusions:
- Age, clinical stage, and tumor biology significantly influence outcomes in stage IV-S neuroblastoma.
- Various biological markers (genetic, molecular, immunological, biochemical) offer insights into disease progression and regression.
- Further research into these markers may refine treatment strategies for improved infant neuroblastoma survival.
Abstract:
A review of stage IV-S neuroblastoma is provided. The possible uses of prognostic features to guide treatment options in this group of infants with neuroblastoma are suggested. The biologic basis for the spontaneous regression of widespread tumor involvement in some infants with stage IV-S neuroblastoma is discussed. The reasons that some infants with IV-S disease progress to a fatal outcome, while most undergo maturation or involution and eventual long term cure are suggested. The influence of such factors as age at diagnosis, clinical staging, and tumor biology on eventual outcome are covered. Biological variables and markers discussed include: genetic (cytogenetics (1p deletions), nuclear genomic content), molecular biologic (N-myc oncogene amplification, mdr-1, ras, and trk, gene expression), immunological (major histocompatibility antigen density, cellular and humoral immunity), and biochemical (creatine kinase isoenzyme profile, neuron specific enolase, ferritin, chromatograffin, lactic acid dehydrogenase and catecholamine levels).
