Image-guided core-needle or surgical biopsy for neuroblastoma diagnosis in children

An IPSO systematic review and meta-analysis examined whether image-guided core needle biopsy can replace surgical biopsy for initial neuroblastoma diagnosis 0:09 0:09. The analysis pooled 8 retrospective studies comprising 490 patients 0:23.

Diagnostic Equivalence

Tissue adequacy did not differ significantly between image-guided core needle biopsy and surgical biopsy 0:23. Biological characterization — the ability to perform molecular and genetic profiling necessary for risk stratification — was also equivalent between approaches 0:23.

Safety Profile

Image-guided core needle biopsy demonstrated superior safety metrics. Intraoperative transfusions occurred more frequently in the surgical biopsy cohort 0:23. Overall complication rates were higher with surgical biopsy 0:23.

Clinical Implications

For pediatric oncologists and surgeons managing newly diagnosed neuroblastoma, these data support image-guided core needle biopsy as the initial diagnostic approach when technically feasible 0:43. The method delivers adequate tissue for both histologic diagnosis and the molecular characterization required by contemporary risk stratification protocols, while reducing transfusion requirements and procedural morbidity.

The retrospective design limits causal inference, and the analysis does not address whether specific tumor locations, patient characteristics, or institutional expertise modify these outcomes. Selection bias likely influenced which patients underwent each procedure in the source studies. Nonetheless, the consistency across 8 independent cohorts and the biological plausibility of the findings — core needle biopsy avoids general anesthesia, laparotomy, and manipulation of vascular tumor beds — support the conclusion that image-guided approaches merit consideration as first-line diagnostic strategy.

What This Review Found

An IPSO systematic review and meta-analysis examined whether image-guided core needle biopsy could replace surgical biopsy for neuroblastoma diagnosis 0:09 0:09. The analysis included 8 retrospective studies with 490 patients 0:23.

The key finding: tissue adequacy and biological characterization were not significantly different between image-guided core needle biopsy and surgical biopsy 0:23 0:23. Both approaches yielded sufficient tissue for diagnosis and molecular profiling 0:23 0:23.

Safety Profile

The image-guided approach showed clear safety advantages 0:23 0:23. Intraoperative transfusions were higher in the surgical biopsy group 0:23, as were overall complications 0:23. This matters for children with neuroblastoma, who often present with bulky, vascular tumors and may already have bone marrow involvement affecting their counts 0:23.

Clinical Implications

For initial tissue diagnosis in neuroblastoma, image-guided core needle biopsy appears safe and effective 0:43. The equivalence in tissue adequacy means you can obtain diagnostic material and perform the molecular characterization required for risk stratification 0:23 0:23—MYCN amplification status, segmental chromosomal aberrations, and other markers that drive treatment decisions 0:23 0:23—without subjecting the patient to an operation.

The lower transfusion and complication rates suggest that when surgical biopsy is chosen, there should be a specific indication beyond simply obtaining tissue 0:23 0:23. Situations where open biopsy might still be preferred include cases where imaging guidance is technically difficult, when concurrent procedures are planned, or when initial core needle attempts have failed 0:43.

What This Doesn't Settle

This is a meta-analysis of retrospective studies, not a randomized trial 0:09 0:09. Selection bias likely influenced which patients received which procedure at each institution 0:23. The analysis doesn't stratify by tumor location, size, or vascularity 0:23—factors that affect both the technical success of image-guided biopsy and the risk of surgical complications. The specific imaging modality and number of core samples obtained aren't detailed 0:23, yet both influence diagnostic yield.

For your practice: image-guided core needle biopsy should be the default approach for obtaining diagnostic tissue in newly diagnosed neuroblastoma 0:43, with surgical biopsy reserved for cases where the percutaneous route is not feasible or has failed 0:43.
