Appearances of screen-detected versus symptomatic colorectal cancers at CT colonography |pdf=|usr=}}{{27048534}} gab.com Text Appearances of screen-detected versus symptomatic colorectal cancers at CT colonography JO: Eur Radiol http://www.kidney.de/pget.php?&tw=1&pmid=27048534 #FOAvip Objectives: The aim of this study was to compare the morphology, radiological stage, conspicuity, and computer-assisted detection (CAD) characteristics of colorectal cancers (CRC) detected by computed tomographic colonography (CTC) in screening and symptomatic populations. Methods: Two radiologists independently analyzed CTC images from 133 patients diagnosed with CRC in (a) two randomized trials of symptomatic patients (35 patients with 36 tumours) and (b) a screening program using fecal occult blood testing (FOBt; 98 patients with 100 tumours), measuring tumour length, volume, morphology, radiological stage, and subjective conspicuity. A commercial CAD package was applied to both datasets. We compared CTC characteristics between screening and symptomatic populations with multivariable regression. Results: Screen-detected CRC were significantly smaller (mean 3.0 vs 4.3 cm, p?<?0.001), of lower volume (median 9.1 vs 23.2 cm3, p?<?0.001) and more frequently polypoid (34/100, 34 % vs. 5/36, 13.9 %, p?=?0.02) than symptomatic CRC. They were of earlier stage than symptomatic tumours (OR?=?0.17, 95 %CI 0.07-0.41, p?<?0.001), and were judged as significantly less conspicuous (mean conspicuity 54.1/100 vs. 72.8/100, p?<?0.001). CAD detection was significantly lower for screen-detected (77.4 %; 95 %CI 67.9-84.7 %) than symptomatic CRC (96.9 %; 95 %CI 83.8-99.4 %, p?=?0.02). Conclusions: Screen-detected CRC are significantly smaller, more frequently polypoid, subjectively less conspicuous, and less likely to be identified by CAD than those in symptomatic patients. Key Points: ? Screen-detected colorectal cancers (CRC) are significantly smaller than symptomatic CRC.? Screening cases are significantly less conspicuous to radiologists than symptomatic tumours.? Screen-detected CRC have different morphology compared to symptomatic tumours (more polypoid, fewer annular).? A commercial computer-aided detection (CAD) system was significantly less likely to note screen-detected CRC.
