Description
Diyang Zhu and co-authors test whether radiation after surgery helps a set class of lung cancer patients. Their 2024 study uses registry data on 1,471 older patients with stage IIIA cancer spread to mid-chest nodes. All had the tumour fully removed, and about two in five got radiation.
The radiation group lived longer at one and three years in raw terms. The edge concentrated in patients with more than one positive node. There, both overall and cancer-specific survival improved with radiation. Patients with a single positive node gained nothing clear. The authors urge trials to confirm the split. Node count may decide who should get the extra treatment.
