This study aimed to describe and assess the feasibility of lung and intercostal upper abdomen ultrasonography as pretreatment imaging of EOC metastases of supradiaphragmatic and subdiaphragmatic areas. A preoperative ultrasound examination of consecutive patients suspected of having EOC was prospectively performed using transvaginal, transabdominal, and intercostal lung and upper abdomen ultrasonography. A surgical-pathological examination was the reference standard to ultrasonography. Among 77 patients with histologically proven EOC, supradiaphragmatic disease was detected in 13 cases: pleural effusions on the right (n = 12) and left (n = 8) sides, nodular lesions on diaphragmatic pleura (n = 9), focal lesion in lung parenchyma (n = 1), and enlarged cardiophrenic lymph nodes (n = 1). Performance (described with area under the curve) of combined transabdominal and intercostal upper abdomen ultrasonography for subdiaphragmatic areas (n = 77) included the right and left diaphragm peritoneum (0.754 and 0.575 respectively), spleen hilum (0.924), hepatic hilum (0.701), and liver and spleen parenchyma (0.993 and 1.0 respectively). It was not possible to evaluate the performance of lung ultrasonography for supradiaphragmatic disease because only some patients had this region surgically explored. Preoperative lung and intercostal upper abdomen ultrasonography performed in patients with EOC can add valuable information for supradiaphragmatic and subdiaphragmatic regions. A reliable reference standard to test method performance is an area of future research. A multidisciplinary approach to ovarian cancer utilizing lung ultrasonography may assist in clinical decision-making.<\/jats:p>","DOI":"10.3390\/diagnostics10020085","type":"journal-article","created":{"date-parts":[[2020,2,6]],"date-time":"2020-02-06T02:59:18Z","timestamp":1580957958000},"page":"85","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Lung and Intercostal Upper Abdomen Ultrasonography for Staging Patients with Ovarian Cancer: A Method Description and Feasibility Study"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2376-4663","authenticated-orcid":false,"given":"Maciej","family":"Stukan","sequence":"first","affiliation":[{"name":"Department of Gynecologic Oncology, Gdynia Oncology Center, Pomeranian Hospitals, 81-519 Gdynia, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3951-1134","authenticated-orcid":false,"given":"Antonio","family":"Bugalho","sequence":"additional","affiliation":[{"name":"CUF Infante Santo Hospital, CUF Descobertas Hospital, NOVA Medical School, 1350-070 Lisbon, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Amanika","family":"Kumar","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Division of Gynecologic Surgery, Mayo Clinic, Rochester, MN 55902, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Julita","family":"Kowalewska","sequence":"additional","affiliation":[{"name":"Department of Radiology, Pomeranian Hospitals, 81-519 Gdynia, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9127-7368","authenticated-orcid":false,"given":"Dariusz","family":"\u015awietlik","sequence":"additional","affiliation":[{"name":"Department of IT and Biostatistic, Gda\u0144sk Medical University, 80-211 Gda\u0144sk, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Natalia","family":"Buda","sequence":"additional","affiliation":[{"name":"Internal Medicine, Connective Tissue Diseases and Geriatrics Department, Medical University of Gda\u0144sk, 80-210 Gda\u0144sk, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ma\u0142gorzata","family":"Pietrzak-Stukan","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Medicover Medical Center Gdansk, 80-309 Gda\u0144sk, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Miros\u0142aw","family":"Dudziak","sequence":"additional","affiliation":[{"name":"Department of Gynecologic Oncology, Gdynia Oncology Center, Pomeranian Hospitals, 81-519 Gdynia, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,2,5]]},"reference":[{"key":"ref_1","unstructured":"(2020, February 03).
