Head and neck cancer survivors: a third have no smoking history recorded, and most eligible are not screened for lung cancer

Design

Cross-sectional analysis of national survey data (BRFSS 2022)

Population

US adults who had survived head and neck cancer

Primary outcome

Lung cancer screening prevalence by USPSTF eligibility

Effect

Screened: 64% (2013-eligible), 40% (2021-eligible), 32% (ineligible); >1/3 lacked smoking data

Using 2022 US Behavioral Risk Factor Surveillance System data, this analysis looked at lung cancer screening among head and neck cancer survivors, a group at raised risk of a second primary in the lung.

More than a third of survivors lacked the smoking history needed to judge eligibility. Screening reached 64% of those eligible under the 2013 criteria but only 40% of those newly eligible under the broader 2021 criteria, and 32% of those eligible under neither. Widening eligibility did not bring a matching rise in scanning.

The finding is from a US survey, but the underlying gap — missing pack-years and no referral pathway — applies to any head and neck follow-up clinic. The ENT surgeon sees these patients most often in the years after treatment.

• Record pack-years and quit date at the first follow-up visit.
• Check eligibility for low-dose CT screening against your national criteria.
• Refer eligible survivors, or ask the GP to, and note it in the letter.
• Remember surveillance CT of the neck does not screen the lungs.
• In India, organised lung screening is not established; the practical step is a low threshold for chest imaging in heavy smokers.

Why it matters

The clinic following these patients most closely is often not the one thinking about their lungs.

Don't overread it

A US self-report survey; the exact rates will not transfer, though the missing-data problem likely does.

The statistics, in plain English

These are survey percentages from self-report, not measured scan rates. Survey data can over- or under-state screening, but a third missing the information needed even to judge eligibility is itself the finding.
