To determine usual imaging practices for providers at MSKCC, median frequency of CT or MRI of the abdomen\/pelvis was calculated among patients with a long-term remission (defined as at least 1 year) treated by each provider. Cox proportional hazards models were used to examine differences in OS and time to recurrence among patients treated by providers with high versus low imaging frequency practices, with additional subgroup analysis among patients with elevated CA-125 levels &gt;35 U\/mL at diagnosis. Chi-square tests were used to examine differences in the proportion of patients who enrolled in clinical trials or underwent secondary cytoreductive surgery (SCS) by imaging frequency. <jats:bold>Results:<\/jats:bold> A total of 543 patients were treated by providers with high imaging frequency (&gt;1 scan every 12 months) and 141 were treated by providers with low imaging frequency (\u22641 scan every 12 months). Time to recurrence was shorter among patients treated by providers with high versus low imaging frequency (18.0 vs 19.2 months; hazard ratio, 1.33; <jats:italic>P<\/jats:italic>=.003). Results were similar when restricted to patients with elevated CA-125 levels at diagnosis. There was no significant difference in OS, clinical trial enrollment, or SCS by imaging practice. <jats:bold>Conclusions:<\/jats:bold> Within the limitations of this retrospective analysis, patients with advanced ovarian cancer treated by high-frequency-imaging providers had earlier detection of recurrence. Future analyses in a larger population are warranted to elucidate the risks versus benefits of surveillance imaging.<\/jats:p>","DOI":"10.6004\/jnccn.2019.7376","type":"journal-article","created":{"date-parts":[[2020,4,7]],"date-time":"2020-04-07T21:52:40Z","timestamp":1586296360000},"page":"414-419","source":"Crossref","is-referenced-by-count":3,"title":["Impact of Provider Imaging Practices on Survival Outcomes in Advanced Ovarian Cancer"],"prefix":"10.6004","volume":"18","author":[{"given":"Angela K.","family":"Green","sequence":"first","affiliation":[{"name":"1Department of Medicine, and"},{"name":"2Center for Health Policy and Outcomes, Memorial Sloan Kettering Cancer Center, New York, New York."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Deborah","family":"Korenstein","sequence":"additional","affiliation":[{"name":"1Department of Medicine, and"},{"name":"2Center for Health Policy and Outcomes, Memorial Sloan Kettering Cancer Center, New York, New York."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carol","family":"Aghajanian","sequence":"additional","affiliation":[{"name":"1Department of Medicine, and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Brooke","family":"Barrow","sequence":"additional","affiliation":[{"name":"2Center for Health Policy and Outcomes, Memorial Sloan Kettering Cancer Center, New York, New York."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael","family":"Curry","sequence":"additional","affiliation":[{"name":"2Center for Health Policy and Outcomes, Memorial Sloan Kettering Cancer Center, New York, New York."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Roisin E.","family":"O\u2019Cearbhaill","sequence":"additional","affiliation":[{"name":"1Department of Medicine, and"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"4047","reference":[{"key":"ref51","doi-asserted-by":"crossref","first-page":"k2387","DOI":"10.1136\/bmj.k2387","article-title":"Prevalence and outcomes of incidental imaging findings: umbrella review","volume":"361","author":"O\u2019Sullivan","year":"2018","journal-title":"BMJ"},{"key":"ref141","doi-asserted-by":"crossref","first-page":"1427","DOI":"10.1001\/jamaoncol.2016.1842","article-title":"Use of CA-125 tests and computed tomographic scans for surveillance in ovarian cancer","volume":"2","author":"Esselen","year":"2016","journal-title":"JAMA Oncol"},{"key":"ref161","doi-asserted-by":"crossref","first-page":"194","DOI":"10.1001\/jamaoncol.2015.31","article-title":"Diagnostic imaging use for patients with cancer: opportunities to enhance value","volume":"1","author":"Swisher-McClure","year":"2015","journal-title":"JAMA Oncol"},{"key":"ref201","doi-asserted-by":"crossref","first-page":"2262","DOI":"10.1093\/annonc\/mdq215","article-title":"Surveillance CT scans are a source of anxiety and fear of recurrence in long-term lymphoma survivors","volume":"21","author":"Thompson","year":"2010","journal-title":"Ann Oncol"},{"key":"ref81","doi-asserted-by":"crossref","first-page":"2262","DOI":"10.1093\/annonc\/mdq215","article-title":"Surveillance CT scans are a source of anxiety and fear of recurrence in long-term lymphoma survivors","volume":"21","author":"Thompson","year":"2010","journal-title":"Ann Oncol"},{"key":"ref121","doi-asserted-by":"crossref","first-page":"280","DOI":"10.1016\/j.ygyno.2015.02.021","article-title":"Improving quality and decreasing cost in gynecologic oncology care.
