1985년 1월에서 1994년 12월까지 10년동안 원주 기독병원 산부인과에서 수술 후 경계성 난소종양 39예를 대상으로 하여 다음과 같은 결론을 얻었다. 1. 경계성 난소종양의 빈도는 전체 군의 27.3%였다. 2. 경계성 난소종양의 연령분포는 12세에서 77세로 평균연령이 39.1세였고, 40세에서 제일 많았다. 3. 경계성 난소종양은 미산부에서 가장 많았다. 4. 경계성 난소종양의 증상은 종괴촉지, 동통, 복부팽창, 질 출혈 순이었다. 5. 경계성 난소종양의 조직학적 분포는 점액성 48.7%, 장액성 43.6%, 미분화세포암 5.1%, 과립막 세포종 2.6%였다. 6. 경계성 난소종양의 암기별 분포는 I기가 36예(92.3%), III기가 3예(7.7%)였다. 7. 경계성 난소종양의 침범이 양측성인 경우가 3예(7.7%), 우측 난소인 경우가 22예(56.4%), 좌측난소인 경우가 14예(35.9%)였고, 종양의 크기는 최단지경 1 cm에서 최장직경 28 cm였고 평균 14.1 cm였다. 종양의 용적은 최소용적이 1.046 cm^3, 최대용적이 7322.000 cm^3였고, 평균 1242.20 cm^3였다. 8. 경계성 난소종양 중 18예(46.2%)에서 보존적 수술을 하였고, 21예(53.8%)에서 전자궁적출술과 양측난소 및 난관절제술을 하였으며 18예(46.2%)에서 수술 후 항암치료를 하였고 추적 중 사망한 예는 없었다.

This study was planned to evaluate the clinical and histopathological status of the borderline malignant ovarian tumors, which were made on a series of 39 cases with borderline malignant ovarian tumor, who were admitted, operated and confirmed with postoperative histopathological study at department of obstetrics and gynecology, Yonsei Uviversity Wonju Christian Hospital, during the period of 1- years from 1985 Jan, to 1994 Dec. The result obtained were as follows: 1. The incidence of borderline malignant ovarian tumor among 143 cases of total group was 27.3%. 1. Age distribution revealed between 12 and 77 years old, mean age was 39.1 years old. 3. As for the parity distribution of borderline malignant ovarian tumor, nulliparity was most common(43.7%). 4. The most frequent chief complaint was palpable mass(71.7%), followed by abdominal pain(12.8%), abdominal distenstion(10.3%), vaginal bleeding(2.6%) and urinary frequency(2.6%). 5. Among the borderline malignant ovarian tumors by histopatholgical classfication, mucinous tumor was most frequently reveal in 19 cases(48.7%), serous tumor in 17 cases(43.6%), mixed tumor in 2 cases (5.1%), granulosa cell tumor in 1case(2.6%). 6. According to FIGO classification the patients were classified as: stage I a(71.8%), stage I b(2.6%), stage Ic(17.9%), stage III b(2.6%), stage III c(5.1%). 7. Right site was 56.4%, left site was 35.9%, and bilaterality was 7.7% in borderline malignant ovarian tumor. 8. Mean volume was 1242.20 cm^3 in borderline malignant ovarian tumor. 9. In the 39 cases of borderline malignant ovarian tumor, 18 cases were managed by conservative operation, the other 21 cases were managed by extripative operation and postperative chmotherapy was given in 19 cases.
