2 treatment settings, 2 with more than one named option. Each section lays out the options the standard of care names, what each is for, the trials behind them with their recorded results, the side effects and cautions on record, and questions to ask. Built from the cancer page's standard-of-care rows; nothing here is advice for your case.
Selpercatinib (LIBRETTO-431) as preferred; pralsetinib as an alternative.
Selpercatinib is a selective RET inhibitor approved for any tumour with a RET fusion, with a further label update in July 2026.
Pralsetinib is the second selective RET pill for lung cancer, less used than selpercatinib after a change of owner and label.
PFS HR 0.46.
Objective response 64 percent after platinum chemotherapy and 85 percent in previously untreated RET fusion-positive non-small-cell lung cancer; intracranial response 91 percent.

Platinum-pemetrexed with or without pembrolizumab; clinical trial of a next-generation RET inhibitor; local radiotherapy for oligoprogression.
Pemetrexed is the chemotherapy that, with a platinum drug, became the first approved treatment for mesothelioma in 2004, and is still the backbone today.
Carboplatin is a platinum chemotherapy that crosslinks DNA; it is part of the standard pre-surgery regimen for triple-negative breast cancer.
Pembrolizumab is a PD-1 blocking antibody approved in more than 40 settings, from melanoma and lung cancer to the first tumour-agnostic approval for mismatch-repair-deficient tumours in 2017, and before and after surgery in triple-negative breast cancer. A subcutaneous form arrived in 2025, and it is the backbone partner for ADCs and personalised neoantigen vaccines.
Stereotactic body radiotherapy converges multiple beams with sub-millimetre accuracy to deliver tumour-destroying doses in one to five outpatient sessions, doing the job of surgery for inoperable early lung cancer and for metastases in liver, spine and brain. Tumour size and location limit its use, and late toxicity is a concern near the central airways.
