Description
Sun Choi and co-authors ask whether surprise node spread found after lung cancer surgery hurts survival as much as known spread. Their 2025 study reviews 177 patients whose removed tissue confirmed N2 nodal disease. Scans and needle sampling staged them before the operation.
Over half the group, about fifty-three percent, were upstaged only after surgery. The surprise nodes cluster under the carina and near the aorta, and two in five measure under five millimeters. Five-year survival matches the known-spread group. Freedom from progression actually runs better in the upstaged group. The authors suggest small hidden nodes behave less aggressively than bulky known disease, easing fears that missed staging alone dooms these patients.
