[Frequency of recurrence and repeated development of ovarian tumors after conservative operations]

Study on the late results of 330 preserving operations for benign ovarian tumors has indicated that the recurrence and redevelopment of the tumor occurs in 13.8% of female patients. In a group of females primarily operated at the age under 45 the development of cancer in a retained ovary was noted in 0.78% of cases, while in the operated patients aged over 45--in 5.2%. It was found that the frequency of recurrences and redevelopment of ovarian tumor is dependent on the extent of surgical intervention and histological structure of the resected neoplasm. The data obtained enabled bilateral ovariectomy to be recommended in menopausal women operated for benign ovarian tumors. The females who underwent resection of the ovary or unilateral ovariectomy should be kept under a dispensary supervision.
