Patients newly diagnosed with EGFR-mutated advanced lung cancer now have a first-line option that improves survival over osimertinib, particularly if they have high-risk features. The trade-off is intravenous (now subcutaneous) infusions and considerably more skin, nail and clotting toxicity, so osimertinib alone remains reasonable for those who prioritise convenience and tolerability. Both this regimen and osimertinib plus chemotherapy (FLAURA2) are approved; there is no direct comparison.

Patients with small-cell lung cancer that has relapsed after chemotherapy now have a drug that works far better than topotecan or lurbinectedin, and it is the first T-cell engager approved for a solid tumour. Treatment requires inpatient monitoring for the first doses because of cytokine release syndrome, which most centres now manage on a short-stay basis. It does not yet apply to first-line treatment, where trials are ongoing.

Patients with operable stage II-III lung cancer without EGFR or ALK alterations should have chemo-immunotherapy discussed before surgery rather than only afterwards. Three pre-operative cycles do not compromise the operation and improve cure rates. Whether to continue immunotherapy after surgery, as the perioperative trials do, and whether patients with pCR need any further treatment, remain open questions.

For ALK-positive advanced lung cancer, lorlatinib as the first drug offers the possibility of many years without progression and strong protection against brain metastases. Alectinib and brigatinib remain alternatives with a gentler side-effect profile; the choice weighs lorlatinib's cognitive, metabolic and weight effects against its unmatched duration of control.

Most patients with newly diagnosed advanced non-squamous lung cancer that lacks a targetable mutation should receive chemotherapy plus pembrolizumab; those with PD-L1 of 50% or more may reasonably receive pembrolizumab alone. About one in five patients is alive at five years, compared with roughly one in ten with chemotherapy alone. Patients with EGFR or ALK alterations were excluded and should have targeted therapy first.
