Lung cancer in never smokers: from early detection to prevention

Lung cancer in never smokers: from early detection to prevention
Lung cancer in never smokers (LCINS) is a growing global health challenge. Unlike smoking-related lung cancer, LCINS is characterized by distinct epidemiological patterns and unique molecular pathogenesis and, consequently, requires different clinical management approaches. Unfortunately, for patients with lung cancer who have never smoked, symptoms are nonspecific and often dismissed due to these patients not fitting a high-risk profile (e.g., smoker), underscoring the need for improved detection and interception. Emerging risk factors, including germline variants, clonal hematopoiesis, and environmental exposures, offer new avenues for risk stratification and preventive strategies. While low-dose computed tomography screening shows promise in high-risk subgroups, challenges remain in optimizing cost-effectiveness. Novel prevention approaches, from interleukin (IL)-1β inhibition to cancer vaccines, are under investigation. This opinion article discusses why LCINS demands unique clinical and research paradigms to address its biological complexity.

Lung cancer cells (shown) in mice can connect with nearby neurons to send a ‘shutdown’ signal to the brain that suppresses tumour-killing immune cells.

APOBEC rate averages versus time gained. This scatter plot illustrates the positive relationship between the average APOBEC rate across sites within patients and the corresponding time gained in each patient.

Expected time until the first resistance mutation without complete suppression of APOBEC (purple bars) and with complete suppression of APOBEC (black bars) in each patient, expressed in molecular clock units, and the consequent expected percentage of time that could have been gained before resistance arose with APOBEC inhibited. Resistance-associated variants were identified by Caswell et al. and Isozaki et al. in each patient
