H. Hayashi et al., Bilateral oophorectomy in asymptomatic women over 50 years old selected byovarian cancer screening, GYNECOL OBS, 47(1), 1999, pp. 58-64
The purpose of this study was to evaluate bilateral oophorectomy in women o
ver 50 years old found to have an adnexal mass using transvaginal ultrasono
graphy (TVS) as a mass screening. With TVS a total of 23,451 women without
symptoms were examined for ovarian cancer at annual screening for uterine c
ervical cancer. Two hundred fifty-eight women over 50 years old persistentl
y had abnormal TVS results and 95 women gave informed consent for surgical
tumor removal. In the 95 women operated, 7 malignant ovarian cancers were f
ound, Especially adnexal masses which were thought to be benign were treate
d by laparoscopic surgery.
