The risk of local recurrence for non-small cell carcinomas of the lung is much more common for those of squamous cell histology than the others and averages 20%–30% overall. The greatest risk, however is of distant metastases which occur in 70%–80% of patients, regardless of stage. Almost all recurrences are seen within five years, and of the distant metastatic sites, the brain is most commonly affected. In this patient with Stage II disease, radiation therapy would be a consideration to reduce the incidence of local recurrence, but not chemotherapy. After five years, the highest risk would be from a new lung cancer rather than a recurrence.
