Analysis of Clinical Characteristics and Therapeutic Effects in Children
with Non-High Risk Neuroblastoma with Spinal Canal Involvement
Abstract
Objectives: Summarized the clinical characteristics of non-high risk
neuroblastoma with spinal canal involvement. Patients and Methods:
Retrospective, single center cohort study of non-high risk patients
treated for NB (from March first 2007 to June 30th 2019) with
intraspinal extension. We used the Kaplan-Meier curve to analyze and
describe the prognosis. All patients followed up to April 30th, 2020.
Results: 46 patients were included among the 371 patients. Median age
was 13 months, median course of disease was 1 month and median follow up
time was 39.5 months. The most prevalent initial symptoms were
neurological motor and sensory deficit. The primary sites of the
patients were posterior mediastinum. There were 19 patients divided in
low risk group and others were in middle risk group. None patient died
during the follow up time and 2 patients with progression of the primary
disease. 24 cases received neurosurgical intervention, 18 patients’
muscle strength can recover gradually. 8 patients who with sphincter
dysfunction received laminectomy and all patients recovered normal.
There was an obvious improvement for pain of nerve root in the 17
patients. 14 patients with scoliosis before the laminectomy and the
operation didn’t cause an aggravation of the condition. Conclusion:
There was a short course and young age at diagnosis to the patients. The
primary site usually located in posterior mediastinum. The highest
prevalence of initial symptom was muscle strength abnormal. Neurological
surgery combined with chemotherapy may relieve the symptoms of spinal
canal compression effectively, and improve the quality of life.
