Ultrasound and positron emission tomography for diagnosis of ovarian cancer recurrence

Results of examination of 14 patients with ovarian cancer recurrence were presented. The follow-up after primary treatment included gynecological examination, ultrasonography and determination of CA-125 level in blood serum. Suspected disease recurrence was the indication for positron emission tomography (PET). The results of PET coincided with US findings in diagnosis of ovarian cancer recurrence in 11 (78.7%) patients. In 2 (14.2%) cases disease recurrence was detected only by PET, while it could not be visualized by ultrasound examination. In 1 (7.1%) case PET and US findings were negative but the increased CA-125 level was determined. Mstakes in diagnosis of disease progression and in assessment of tumor involvement were analyzed.
