[Progress in the study of polycythemia vera in children].

Pediatric polycythemia vera is an exceedingly rare myeloproliferative neoplasm characterized by clonal overgrowth of the erythroid lineage. Although research on adult polycythemia vera is relatively well established, standardized diagnostic and therapeutic protocols for pediatric patients are lacking. Due to substantial differences in physiological characteristics and disease progression between children and adults, directly applying adult treatment regimens is not appropriate. Pediatric-specific management strategies tailored to the unique features of children are urgently needed. This article systematically reviews the etiology, clinical manifestations, diagnostic methods, and therapeutic advances of pediatric polycythemia vera, aiming to provide evidence to support clinical decision-making and basic research.
