To assess whether expectant observation of infants ≤ 90 days old with small suprarenal masses (sSRMs) could avoid unnecessary surgery without impacting outcome. Infants ≤ 90 days with a ≤ 5 cm mass, without midline extension or lymph node or distant spread were registered (ClinicalTrials.org:NCT01728155).

About a third of these infants undergo tumor progression requiring antitumor treatment and 10-15% eventually die. In case of metastatic progression, it may occur either at 4S sites (mainly liver) or sites characterizing stage 4 (mainly bone).

Methods: We investigated a cohort of 172 infants diagnosed with stage 4S neuroblastoma between 1994 and 2013. Of 160 evaluable patients, 62 underwent upfront resection of the primary tumor and 98 did not.
