Preoperative Radiographic Assessment Predicts Incomplete Cytoreduction in Patients with Low Grade Mucinous Adenocarcinoma of the Appendix.

External validation of two radiographic scoring systems to predict complete cytoreduction showed that inter-rater agreement for both systems was good. Both scoring systems predicted incomplete cytoreduction. Applying a systematic approach to preoperative imaging review is recommended to improve treatment selection by minimizing morbidity associated with incomplete CRS and help to set patient expectations.
