Needle core vs open biopsy for diagnosis of intermediate- and high-risk neuroblastoma in children.
ABSTRACT Open biopsy has been the mainstay for definitive diagnosis of neuroblastoma in pediatric patients. However, needle core biopsy may represent a faster, less invasive, and safer alternative to open biopsy in children. The purpose of this study was to compare safety and efficacy between needle core and open biopsy in the diagnosis of patients with intermediate- and high-risk neuroblastoma at our institution.
We retrospectively reviewed the medical records of children with intermediate- and high-risk neuroblastoma who underwent open or needle core biopsies from 2002 to 2010. Data collected included patient demographics, tumor size, sample adequacy for diagnosis and risk stratification (histology and cytogenetics), length of hospital stay, time to initiate chemotherapy after biopsy, need for repeat biopsy, and both intraoperative and postoperative complications. Mann-Whitney U and Fisher's exact tests were used for statistical analysis.
During the study period, 7 patients underwent needle core primary biopsies (5 intermediate-risk primary tumors and 2 high-risk primary tumors), and 4 patients underwent needle core biopsy for metastatic tumors, whereas 21 patients had open biopsies (10, intermediate risk; 11, high risk). Median age at biopsy and median tumor size were similar in both groups. There was no significant difference in adequacy of biopsy, need for repeat biopsy, time to initiate chemotherapy, length of stay, or minor complications. The rate of major complications differed significantly between the 2 groups with 0% after needle core biopsy vs 48% after open biopsy (P = .027).
In children, needle core biopsy is comparable in efficacy with open biopsy in the diagnosis of intermediate- and high-risk neuroblastoma with significantly lower rates of major postoperative complications. These findings warrant a larger scale evaluation of diagnostic needle core biopsies in pediatric patients with solid tumor.

ABSTRACT: Ultrasound-guided core needle biopsy of abdominal and pelvic masses in adults has gained tremendous popularity. However, the application of the same treatment in children is not as popular because of apprehensions regarding inadequate tissues for the biopsy and accidental puncture of vital organs. Data of the application of ultrasound-guided core needle biopsy in 105 pediatric patients with clinically or ultrasound-diagnosed abdominopelvic masses were reviewed. Diagnostic procedures were conducted in our institution from May 2011 to May 2013. The biopsies were conducted on 86 malignant lesions and 19 benign lesions. 86 malignant tumors comprised neuroblastomas (30 cases), hepatoblastomas (15 cases), nephroblastomas (11 cases), and primitive neuroectodermal tumors/malignant small round cells (6 cases). Among malignant tumor cases, only a pelvic primitive neuroectodermal tumor did not receive a pathological diagnosis. Therefore, the biopsy accuracy was 98.8 % in malignant tumor. However, the biopsies for one neuroblastomas and one malignant small round cell tumor were inadequate for cytogenetic analysis. Therefore, 96.5 % of the malignant tumor patients received complete diagnosis via biopsy. 19 benign tumors comprised mature teratoma (10 cases), hemangioendothelioma (3 cases), paraganglioma (2 cases), and infection (2 cases). The diagnostic accuracy for benign neoplasm was 100 %. Five patients experienced postoperative complications, including pain (2 patients), bleeding from the biopsy site (2 patients), and wound infection (1 patient). Ultrasound-guided core needle biopsy is an efficient, minimally invasive, accurate, and safe diagnostic method that can be applied in the management of abdominal or pelvic mass of pediatric patients.Pediatric Surgery International 11/2013; · 1.22 Impact Factor
