Evaluation of Image-Defined Risk Factor (IDRF) Assessment in Patients With Intermediate-risk Neuroblastoma: A Report From the Children's Oncology Group Study ANBL0531.
Background: The International Neuroblastoma Risk Group (INRG) classifier utilizes a staging system based on pretreatment imaging criteria in which image-defined risk factors (IDRFs) are used to evaluate the extent of locoregional disease. Children's Oncology Group (COG) study ANBL0531 prospectively examined institutional determination of IDRF status and compared that to a standardized central review.
Methods: Between 9/2009-6/2011, patients with intermediate-risk neuroblastoma were enrolled on ANBL0531 and had IDRF assessment at treating institutions. Paired COG pediatric surgeons and radiologists performed blinded central review of diagnostic imaging for the presence or absence of IDRFs. Second blinded review was performed in cases of discordance. Comparison of local and central review was performed using the Kappa coefficient to determine concordance in IDRF assessment.
Results: 211 patients enrolled in ANBL0531 underwent IDRF assessment; 3 patients were excluded due to poor image quality. Central reviewer pairs agreed on the presence or absence of any IDRF in 170/208 (81.7%; κ = 0.48) cases. Thirteen (6.3%) cases could not be adjudicated after second blinded review. Radiologists were more likely to identify IRDFs as present than surgeons (p < 0.001). Local and central reviewers agreed on the presence or absence of any IDRF in only108/208 (51.9%; κ = 0.06) cases.
Conclusions: Among experienced pediatric surgeons and radiologists participating in central review, concordance was moderate, with agreement in 81.7% of cases. On comparison of local and central assessment of IDRFs, concordance was poor. These data indicate that greater standardization, education, technology, and training are needed to improve the assessment of IDRFs in children with neuroblastoma.
期刊介绍：
The journal presents original contributions as well as a complete international abstracts section and other special departments to provide the most current source of information and references in pediatric surgery. The journal is based on the need to improve the surgical care of infants and children, not only through advances in physiology, pathology and surgical techniques, but also by attention to the unique emotional and physical needs of the young patient.
