PURPOSE: To explore the utility of CTE in the evaluation of bowel invasion in patients with primary ovarian, fallopian tube, and peritoneal cancer.
METHODS: This observational study included 73 patients who received CTE before operation between September 2019 and December 2021. Two radiologists reviewed CTE images, focusing on the sites and depth of bowel involvement. Based on the findings during surgical exploration, we evaluated the diagnostic power, like sensitivity, specificity, accuracy, positive predictive value (PPV), negative predictive value (NPV), positive likelihood ratio (+ LR), and negative likelihood ratio (- LR) of CTE. Additionally, the characteristic images of bowel involvement on CTE corresponding to surgical findings were shown in the study.
RESULTS: The rate of macroscopic bowel invasion in this cohort was 49.31% (36/73), of which eight patients had small bowel involvement, 17 patients had colon involvement and 27 patients had sigmoid-rectum involvement. CTE detected bowel invasion in the small intestine with a sensitivity, specificity, PPV, NPV, and accuracy of 87.50%, 92.31%, 58.33%, 98.36%, 91.78%; for colon, the statistics were 58.82%, 96.43%, 83.33%, 88.52%, 87.67% and for sigmoid-rectum 62.96%, 82.61%, 68.00%, 79.17%, 75.34%, respectively.
CONCLUSION: CTE appeared a preferable diagnostic power on the small bowel and colon invasion in patients with primary ovarian, fallopian tube, and peritoneal cancer.
