The incidence of second primary tumors in long-term survivors of small-cell lung cancer.

Abstract

In this review, SCLC showed one of the highest incidences of SPTs reported in aerodigestive tract malignancies. A long-term survivor was more likely to have an SPT than a relapse of SCLC. Consequently, the odds of death from an SPT compared with that from a relapse increased sharply from 1:13 within 4 years from diagnosis to 8:1 afterwards. Long-term survivors of SCLC would be excellent candidates for chemoprevention trials.
