This scientific event in pediatric oncology focuses on two major childhood solid tumors: nephroblastoma (Wilms tumor) and neuroblastoma. The program aims to provide participants with an updated overview of the epidemiology, pathophysiology, diagnostic approaches, and therapeutic strategies related to these malignancies. Emphasis will be placed on the role of multidisciplinary collaboration, integrating clinical findings, imaging, pathology, and molecular biology to optimize patient management. Through expert lectures and case-based discussions, attendees will enhance their understanding of current treatment protocols, prognostic factors, and recent advances in pediatric oncopathology and oncology, while also addressing ethical and psychosocial aspects of care in children with cancer.
