Ultrasonography for early detection of ovarian carcinoma

Ultrasound scan for detection of ovarian enlargements was performed in a target group of out-patients attending the clinic for various reasons in the 40-70 years range. Overall 805 women were examined, in 99% of whom the ovaries and/or their vessels could be identified. Pathological findings were suspected in 83 patients at the first scan, and were confirmed in 50 after a repeat scan, 39 of whom subsequently underwent surgery. Various ovarian lesions were found in 35 women, including five mucinous and serous cystadenomas, one carcinoma, two borderline tumours, and a cancer of the caecum. None of the borderline or malignant ovarian lesions were found by manual pelvic examination. Ultrasound screening appears to be a useful diagnostic aid, though its usefulness might be further improved if other risk factors such as heredity and period of ovulatory activity are taken into consideration.
