Ovarian cancer reporting lexicon for computed tomography (CT) and magnetic resonance (MR) imaging developed by the SAR Uterine and Ovarian Cancer Disease-Focused Panel and the ESUR Female Pelvic Imaging Working Group.

Abstract

Imaging evaluation is an essential part of treatment planning for patients with ovarian cancer. Variationin the terminology used for describing ovarian cancer on computed tomography (CT) and magnetic resonance (MR)imaging can lead to ambiguity and inconsistency in clinical radiology reports. The aim of this collaborative projectbetween Society of Abdominal Radiology (SAR) Uterine and Ovarian Cancer (UOC) Disease-focused Panel (DFP)and the European Society of Uroradiology (ESUR) Female Pelvic Imaging (FPI) Working Group was to develop anovarian cancer reporting lexicon for CT and MR imaging. Twenty-one members of the SAR UOC DFP and ESUR FPI working group, one radiology clinical fellow,and two gynecologic oncology surgeons formed the Ovarian Cancer Reporting Lexicon Committee. Two attendingradiologist members of the committee prepared a preliminary list of imaging terms that was sent as an onlinesurvey to 173 radiologists and gynecologic oncologic physicians, of whom 67 responded to the survey. Thecommittee reviewed these responses to create a final consensus list of lexicon terms. An ovarian cancer reporting lexicon was created for CT and MR Imaging. This consensus-based lexiconhas 6 major categories of terms: general, adnexal lesion-specific, peritoneal carcinomatosis-specific, lymph node-specific,metastatic disease -specific, and fluid-specific. This lexicon for CT and MR imaging evaluation of ovarian cancer patients has the capacity to improvethe clarity and consistency of reporting disease sites seen on imaging. • This reporting lexicon for CT and MR imaging provides a list of consensus-based, standardized terms and definitions for reporting sites of ovarian cancer on imaging at initial diagnosis or follow-up. • Use of standardized terms and morphologic imaging descriptors can help improve interdisciplinary communication of disease extent and facilitate optimal patient management. • The radiologists should identify and communicate areas of disease, including difficult to resect or potentially unresectable disease that may limit the ability to achieve optimal resection.
