Non-small-cell lung cancer: how to manage RET-positive disease.

ABSTRACT: Targeted therapy has dramatically changed the history and outcomes of oncogene-addicted non-small-cell lung cancer (NSCLC). RET rearrangements are typically observed in about 1-2% of NSCLC, resulting in constitutive activation of downstream signalling pathways commonly involved in cell growth and survival. RET-positive NSCLCs are generally associated with young age, non-smoking history, a high rate of brain metastases at diagnosis and an immunologically 'cold' tumour microenvironment. Multi-kinase inhibitors, such as cabozantinib, lenvatinib and vandetanib, showed limited efficacy but significant toxicity mainly linked to off-target effects. In contrast, two RET-selective tyrosine kinase inhibitors (TKIs), selpercatinib and pralsetinib, demonstrated high response rates and ma
