The role of computed tomography in the evaluation of the spread of ovarian cancer

The aim: To determine the role of CT in the evaluation of the spread of ovarian cancer.

Methods: The data of 64 female patients who underwent abdominal and pelvic CT examinations due to the suspicion of ovarian cancer during 2014–2015 in HLUHS CK were analyzed. All patients were operated and ovarian cancer was confirmed histologically.

Results: The average age of the patients was 60,06 ± 14,95 years. By the histological type, 37 (57,7%) cases of tumor were serous type. By the differentiation degree, 41 (63,5%) cases of tumor were G3. 27 (42,2%) of all the cases of ovarian cancer were diagnosed in the stage IIIC. CT sensitivity in the assessment of pathological lymph nodes was 41,9%, specificity – 81,8%, PPV – 68,4%, NPV – 60,0%, accuracy – 51,6%. CT sensitivity in the evaluation of peritoneal carcinomatosis was 62,5%, specificity – 81,3%, PPV – 90,9%, NPV – 41,9%, accuracy – 67,2%. The CT sensitivity to ascites was – 86,5%, specificity – 88,9%, PPV – 91,4%, NPV – 82,8%, accuracy – 87,5%.

Conclusions: 1. The symptoms of the ovarian cancer spread were determined more frequent in high-grade tumors. 2. Larger ovarian tumors typically were spread to the bladder and rectum. 3. The results of lymph nodes and peritoneal carcinomatosis showed that CT had moderate sensitivity, NPV, and accuracy, but it had high specificity. According to the pathological lymph nodes, PPV was average, but high according to peritoneal carcinomatosis. 4. The evaluation of ascites showed that CT sensitivity, specificity, PPV, NPV, and accuracy were high.

Key words: ovarian cancer, spread, computed tomography.
