For the evaluation of clinical and pathological characteristics of ovarian tumors, a retrospective study was performed on 1164 patients with ovarian tumors who were confirmed with post - operative histopathology at the Department of obstetrics
and
Gynecology, Koryo General Hospital from 1973 to 1992.
1. Among 1164 cases, the incidence of non-neoplastic ovarian cysts, benign and malignant ovarian tumors were 488 cases (41.9%), 594 cases(51.1%0 and 82 cases(7.0%), respectively.
2. Among neoplastic ovarian tumors, cystic teratomas (282 cases, 41.7%) was most common, followed by serous cystadenomas (183 cases, 27.8%) and mucinous cystadenomas (107 cases, 15.7%) in decreasing order of frequency.
3. The age distribution showed that 21 to 50 years age groups were most common in both non-neoplastic ovarian cysts (89.8%) and benign ovariam tumors(81.7%). The most common age group of malignant ovarian tumor was also 21 to 50 years age group
(59.9%), followed by more than 50 years age group (35.3%).
4. Bilaterality was 7.4% in non-neoplastic ovarian cysts, 12.1% in benign ovarian tumors, 46.7% in malignant ovarian tumors and 87.5% in metastatic tumors of ovarian malignancy.
5. The mean size of malignant tumors was larger than that of the benign ovarian tumors. The largest size of the malignant ovarian tumors was in mucinous adenocarcinoma which was about 17.6 cm in average.
6. As for the parity distribution of ovarian tumor patients, nullipara were most common(28.5%) and parity was in inverse relationship with incidence.
7. The most frequent chief complaint was abdominal pain or discomfort (41.9%), followed by abdominal palpable mass(37.7%) and abnormal genital bleeding (8.1%).
8. Ovarian tumors associated with pregnancy were 166 cases(15.7%) in non-neoplastic and benign ovarian tumors. Of the 85 benign ovarian tumors, cystic teratoma was most common in 65.9%.
9. According to FIGO classification of malignant cvarian tumors, stage I (37.8%) was most common, followed by stage IV (29.3%), stage III (21.9%) and stage II(11.0%).
10. As for the surgical teratment of malignant ovarian tumors. Total hysterectomy with bilateral salpingo-oophorectomy was most commonly performed (31.7%). Adjuvant chemotherapy was performed in 37.8%.
