Fast Five Quiz: Non–Small Cell Lung Cancer (NSCLC) and RET Mutation

National Comprehensive Cancer Network guidelines for RET-rearranged positive NSCLC advise that for RET rearrangement discovered before first-line systemic therapy, the recommended treatment is selpercatinib or pralsetinib. However, it is important to note that acquired resistance may limit this strategy's long-term efficacy.

Vandetanib and cabozantinib are considered category 2B therapy. If the disease progresses after first-line treatment, guidelines recommend either selpercatinib or pralsetinib, as well as systemic therapy for NSCLC.

If the RET rearrangement is discovered during the first line of chemotherapy, the guidelines recommend completing a course of systemic therapy, including maintenance therapy, or interrupting therapy followed by selpercatinib or pralsetinib. In appropriate cases, patients may be started on category 2B cabozantinib or vandetanib.
