In 2 patients with stage I lung cancer, tumors recurred at their resection
lines 10 years after the original surgical resections. These cases suggest
that the prognosis of late cancer occurrences after resected primary lung m
alignancies might be related to the interval of time between primary and su
bsequent cancers rather than to their categorization as recurrent or metach
ronous cancers. (C) 1999 by The Society of Thoracic Surgeons.
