Adnexal mass staging CT with a disease-specific structured report compared to simple structured report.

To assess a disease-specific structured report (dsSR) for CT staging of ovarian malignancy compared to a simple structured report (sSR). This is a HIPAA-compliant, IRB-approved study with waiver of informed consent. An adnexal mass-specific structured reporting CT template was developed in collaboration between gynecologic oncologists and diagnostic radiologists. The study population included 24 consecutive women who had a staging CT prior to undergoing debulking surgery for a primary ovarian malignancy. Objective evaluation by radiologists for the presence of 19 key features and subjective evaluation by gynecologic oncologists were performed to assess the clarity and usefulness for procedural planning of dsSR and sSR. Accuracy, sensitivity, and specificity were assessed using operating room notes and pathology reports as the reference standard. Fewer key features were missing from dsSR than sSR: 0.2 ± 0.8 (range 0-2) vs.10.2 ± 1.7 (range 7-14), respectively (p < 0.0001). Compared to sSR, gynecologic oncologists deemed dsSR more helpful (4.3 ± 0.7 vs. 3.7 ± 0.8, p < 0.0001) and easier to understand (4.3 ± 0.6 vs. 3.9 ± 0.7, p = 0.0057) (on a scale 0-5, 0 not helpful/very difficult to understand; 5 extremely helpful/very clear to understand). Gynecologic oncologists reported a higher rate of potential to modify their surgical approach based on dsSR (33-42%) compared to sSR (13-17%), p = 0.004. Disease-specific structured reports were more reliable than simple structured reports in describing key features essential for procedural planning. dsSR was described as more helpful and easier to understand and more likely to lead to modification of the surgical approach by gynecologic oncologists compared to sSR. • Disease-specific structured report is easier to understand and more helpful for planning gynecological surgery as compared with simple structured report. • Disease-specific structured report for pre-operative evaluation of ovarian cancer provides better documentation of essential features required for surgical planning as compared with simple structured report. • Disease-specific structured report has the potential to modify the surgical approach as assessed by gynecologic oncologists.
