Subjects included 8,621 Medicare beneficiaries (age, \u226566 yr) who underwent lung cancer resection with curative intent between 1992 and 2005. A surveillance CT or PET examination was defined as CT or PET imaging performed in an outpatient setting on patients who did not undergo chest radiography in the preceding 30 days.<\/jats:p>\n                    <jats:p>Measurements and Main Results: Overall, imaging use was higher within the first 2 years versus Years 3\u20135 after surgical resection. Use of surveillance CT scans increased sharply from 13.7 to 57.3% of those diagnosed in 1996\u20131997 and 2004\u20132005, respectively. PET scan use increased threefold, from 6.2% in 2000\u20132001 to 19.6% in 2004\u20132005. In multivariable analyses, we observed a 32% increase in the odds of undergoing surveillance CT or PET imaging for every year of diagnosis between 1998 and 2005. There was no substantial decline in the odds of having a surveillance CT or PET scan during each successive follow-up period, suggesting no change in the intensity of surveillance over the first 5 years after surgical resection. The proportion of surveillance CT imaging performed at freestanding imaging centers increased from 18.0% in 1998\u20131999 to 30.6% in 2004\u20132005.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The use of CT and PET imaging for surveillance after curative-intent surgical resection of early-stage lung cancer increased sharply in the United States between 1997\u20131998 and 2005. In the absence of evidence demonstrating favorable outcomes, this practice was likely driven by prevailing expert opinion embedded in clinical practice guidelines made available during that time. Research is clearly needed to determine the role and optimal approach to surveillance thoracic imaging after surgical resection of lung cancer.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1513\/annalsats.201511-768oc","type":"journal-article","created":{"date-parts":[[2016,5,31]],"date-time":"2016-05-31T15:06:14Z","timestamp":1464707174000},"page":"1559-1567","source":"Crossref","is-referenced-by-count":10,"title":["Pattern of Imaging after Lung Cancer Resection. 1992\u20132005"],"prefix":"10.1093","volume":"13","author":[{"given":"Gulshan","family":"Sharma","sequence":"first","affiliation":[{"name":"Department of Internal Medicine"},{"name":"Sealy Center on Aging, and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7510-2664","authenticated-orcid":false,"given":"Shawn P.
