To analyse the relationship between endometriosis and epithelial ovarian cancer.
We analyzed retrospectively the 20 cases associated with endometriosis in 371 cases of epithelial ovarian cancer, and these 20 cases were also compared with the left 351 cases not associated with endometriosis(including endomtriod carcinoma 38 cases and clear cell carcinoma 39 cases).
Among 20 cases, endomtriod carcinoma and clear cell carcinoma were most frequently associated with endometriosis, with 11 cases and 7 cases respectively, there was also 1 case of gland carcinoma and 1 case of serous papillary carcinoma. Cases of carcinomas associated with endometriosis had higher pathological grade and 5-year survival probability (Kaplan-Meier method) than those cases not associated with endometriosis.
There is a close relationship between endometriosis and ovarian endomtriod carcinoma and clear cell carcinoma, the malignant transformation of endometriosis foci may be an important origin of them. Drug therapy is recommended for endomtriosis after the operation. In the treatment of endomtriod carcinoma and clear cell carcinoma, progestin can be used as an accessory method.
