This is exemplified by studies showing that dasatinib, a second-generation tyrosine kinase inhibitor (TKI) approved for Philadelphia chromosome positive chronic myeloid leukaemia, improves established PAH in multiple animal models [5], while its administration before exposure to PH inducers exacerbates pulmonary vascular remodelling and pulmonary artery pressures; histological and haemodynamic changes not observed in rats exposed to dasatinib alone [6].This study demonstrates that R-crizotinib, a frontline therapy for lung cancer, predisposes to and exacerbates PH in animal models. Caution and regular follow-up should be exercised in lung cancer patients treated with the compound. http://bit.ly/39s6stp ER -
