Accelerated linear growth in children with selective tyrosine kinase inhibitior treatment: Hints to a growth factor and sex steroid independent growth promotion mechanism

Raimann Adalbert , Stepien Natalia , Gojo Johannes , Hartmann Gabriele

Background: Postnatal linear growth is characterized by a steady decline of growth velocity in healthy individuals, with the exception of sex-steroid induced pubertal growth. Pharmacologic interventions in growth disorders are limited to systemic application of growth factors such as growth hormone, and CNP analogues in conditions with FGFR3 overactivation. Tyrosine kinase receptor inhibitors (TKI) represent a heterogenous group of drugs, mostly used for oncol...
