The role of computed tomography in the management of ovarian tumours of borderline malignancy.

Ovarian tumours of borderline malignancy are a distinct histological and clinical entity diagnosed in up to 15% of patients presenting with an ovarian neoplasm. Compared with frankly malignant tumours, they have a much better prognosis, present at an earlier age, and the majority are stage 1 at diagnosis. This study reviewed 35 patients with ovarian tumours of borderline malignancy referred to the CRC Medical Oncology Unit at The Christie Hospital over a 9-year period and evaluated the role of diagnostic imaging, in particular, the value of postoperative computed tomography (CT). We conclude that in cases of FIGO stage 1 disease where there is complete macroscopic removal of tumour, there is no need for further routine imaging. If chemotherapy is to be given for patients with more advanced disease, a baseline postoperative abdomino-pelvic CT scan and a post-treatment scan are appropriate investigations.
