One hundred forty-seven cases of ovarian endometriosis, encountered from 1976 to 1999 at Tsukuba University Hospital, were studied to clarify the incidence of malignant transformation. There were 18 cases (12.2%) of atypical endometriosis, among which we found a case (5.6%) of ovarian cancer arising from endometriosis not diagnosed before surgery. This is accounted for 0.7% of all ovarian endometriosis cases. Because the incidence was equal to that of the previous reports, it is most likely that the malignant change in ovarian endometriosis occurred in 0.7% of this disease.
为明确恶变发生率,对1976年至1999年在筑波大学医院收治的147例卵巢子宫内膜异位症患者进行了研究。其中非典型子宫内膜异位症18例(12.2%),其中1例(5.6%)为术前未诊断出的子宫内膜异位症相关卵巢癌。这占所有卵巢子宫内膜异位症病例的0.7%。由于该发生率与既往报道相当,卵巢子宫内膜异位症恶变很可能发生于0.7%的此类疾病患者中。
