Traditionally, radical hysterectomy is the main surgical method for the treatment of early cervical carcinoma and always results in the loss of fertility. But, large numbers of young women are recently being diagnosed with cervical carcinoma and fertility preservation has become a concern. So, there has been a move towards more conservative approaches for the treatment of cervical carcinoma in recent years. Radical trachelectomy, which allows preservation of uterus but removes the cervix, parametrium and upper one third of the vagina, is a conservative but locally radical procedure. We performed radical abdominal trachelectomy with pelvic lymphadenectomy for two cases of invasive cervical carcinomas, which may be the first report in korea. One patient was 37 years old single women who had stage Ib cervical cancer and was disease free for 17 months after treatment. The other patient was 19 years old student who was also single and had stage IIa cervical cancer and was disease free for 14 months after treatment. We report the first two cases and review the literature on radical trachelectomy.

Malignant transformation of mature cystic teratoma (MCT) is an uncommon complication occuring in approximately 1-3%. Any of the constituent tissues of a teratoma has the potential to undergo malignant transformation; squamous cell carcinoma is the most commonly associated cancer, however, adenocarcinomas or carcinoid tumors arising in mature cystic teratoma are uncommon, especially simultaneously. We present an unusual case of postmenopausal women having mucinous adenocarcinoma and strumal carcinoid tumor simultaneously arising in one of bilateral mature cystic teratoma of the ovary. We suggest malignant transformation of MCT should be treated according to the management of the worst histologic diagnosis of the transformations if there are 2 or more malignancies are arised in MCT of the ovary.

목적 : 본병원에서 방사선 단독치료를 받은 자궁경부암 환자의 생존율 및 재발 양상을 분석 하고 이에대한 결과를 비교 분석함으로서 치료방법에 대한 평가를 하고자 하였다. 대상 및 방법 : 1987년 5월부터 1991년 12월까지 자궁경부암병기(FIGO) IB, II A, II B 로 근치목적의 방사선치료를 완료한 220명의 환자를 대상으로 후향적 분석을 시행하였다. 이중 병기 IB환자는 1995년에 개정된 FIGO 분류법에 의해서 분석당시 IB1과 IB2로 재분류를 시행하였다. 방사선치료는 외부방사선치료와 강내조사를 병용하였으며 방사선치료 후 6개월에서 국소종양의 치유여부를 판정하였다. 추적기간은 3개월에서 115개월까지 였으며 평균 62개월이었고 추적율은 $93.6\%$(206/220) 였다. 결과 : 병기별 5년 생존율은 IB1(N=50), IB2(N=15), II A(N=58), II B(N=97)에서 각각 $94\%,\;87\%,\;69\%,\;56\%$였다. 생존과 관계있는 예후인자로는 병기(p=0.00), 진단시 혈색소치(p=0.00), 진단시 종양표지자 수치(p=0.02), 종양의 크기(0.00), 골반단층촬영에서의 임파선전이(p=0.04) 등이 통계적인 유의수준을 보였으나 다요인 분석에서는 병기만이 유일하게 통계적인 유의수준의 차이를 보였다. 판정이 가능한 214명의 방사선치료에 따른 국소종양제어율은 $81\%$였으며, 병기별로보면, IBI, IB2, II A, II B 각각 $100\%,\;86.7\%,\;84.5\%,\;68.1\%$의 결과를 보였다. 치료 후 재발율은 $15.5\%$(27/174)였으며, 병기별로 보면 IBI, IB2, II A, II B 각각 $8\%,\;0\%,\;22.4\%,\;19.4\%$였다. 결론 :촌기 자궁경부암 환자의 치료결과는 이미 보고되어 있는 다른 결과와 비교시 비슷한 수준을 보이나 진행된 II B 환자에서는 낮은 생존율의 결과를 보이고 있으며 이에대한 원인분석과 치료방법의 개선이 필요하다 하겠다. Purpose : We analyzed the survival and failure patterns of cervix cancer patients treated with irradiation alone to evaluate our treatment method and to compare with the others Methods and Materials : Two hundred and twenty cervical cancer patients, Stage IB, II A, and II B who completed the planned treatment between Mar 1987 and December 1991 were analyzed retrospectively. The Stage IB patients were restaged to the Stage IB1 and IB2 by the recently revised FIGO classification, Patients were treated with a combination of external irradiation and the intracavitary brachytherapy Determination of the tumor control was done at the time of 6 months Postirradiation. The follow-up time was ranged from 3 to 115 months and the mean was 62 months and the follow-up rate was $93.6\%$(206/220) Results : The overall 5-year survival rate of Stage IB1 (N=50), IB2(N: 15). II A(N=58), and II B(N=97) was $94\%,\;87\%,\;69\%,\;and\;56\%$. respectively. In the univariate analysis of prognostic factors, stage(0.00), initial Hg level (P=0.00), initial TA-4(tumor-associated) antigen level(p= 0.02), initial CEA level(p=0.02), barrel-shaped tumor(p=0.02), whole cervical involvement (0.00), pelvic tyrnphadenopathy(LAP) in CT(p=0.04), and Post-irradiation adiuvant chemotherapy(P=0.00) were statistically significant in survival analysis. In a while multivariate analysis showed that the stage was the most powerful Prognostic indicator and the Post-irradiation chemotherapy factor also showed the statistical significance. The overall local control rate was $81\%$ and by the stage, $100\%$ in Stage IBI, $86.7\%$ in Stage IBS, $84.5\%$ in Stage IIA, and $68.1\%$ in Stage IIB, respectively The overall tumor recurrence rate was $15.5\%$(27/174) and by the stage, $8\%$(4/50) in Stage IB1, $0\%$(0/l3) in Stage IB2, $22.4\%$(l1/49) in Stage II A, and $19.4\%$(12/62) in Stage II B, respectively. Conclusions : We obtained the similar treatment results to the other's ones in early stage cervical cancer patients. But in Stage II B, the local control rate was lower than that of the other institutes and also the survival was poorer. So it seems to be necessary to reevaluate the treatment method in advanced cervical cancer patients.

목적 :조기 자궁경부암 환자에서 보조적 방사선치료요법은 근치적수술을 시행하고 재발의 위험이 높은 불량한 예후를 갖는 환자에서 시행되고 있다. 이에 저자는 수술후 방사선치료를 받았던 환자의 생존과 치료실패에 영향을 주는 예후인자를 분석하고자 하였다. 대상 및 방법 :전남대학교병원 치료방사선과에서 1985년 8월부터 1988년 12월까지 수술후 방사선치료를 받았던 자궁경부암 병기 IB와 IIA환자 106명중 기록이 충분한 90명을 대상으로 후향적 분석을 시행하였다. 추적율은 $88\%$(78/90)였고 추적기간의 중간간은 64개월이었다. 결과 : 90명에 대한 5년 생존율및 5년 무병생존율은 각각 $80.0\%$, $80.2\%$였다. 다변량생존분석에서 65명을 대상으로 환자의 연령, 병기, 조직학적 분류, 수술전 혈중 CIA 농도, 출산력, 경부침윤정도, 종양의 육안적 크기, 종양의 궤양성 유무, 임파선 전이 유무, 수술절단면의 소견, 항암제치료 유무를 변수로 분석결과 수술절단면의 조직학적인 소견(p=0.005), 임파선전이유무(p=0.005)가 통계학적으로 의미있는 예후인자였다. 추적기간중 13명에서 재발이 확인되었고 부위별로 보면 골반내 국소재발이 5명, 원격전이가 8명 이었으며 수술후 3개월에서 39개월사이에 발견되었으며 중간값은 19개월이었다. 골반내 전이는 선암(p=0.034)과 경부침윤 10mm 이상(p=0.02) 그리고 항암제치료(p=0.023)를 시행하였던 환자군에서, 원격 전이에 있어서는 임파선전이와 수술절단면에서 암세포가 양성을 보였던 환자군에서 각각 더 높은 전이율을 보였다. 치료에 의한 합병증을 호소하였던 환자는 15명이었으며 가장 흔한 증상은 혈변이나 혈뇨였고 중증의 합병증을 보인 환자는 없었다. 결론 : 이에 저자는 조기자궁경부암 IB와 IIA환자에서 수술병리학적소견중 임파선전이와 불충분한 수술적절제가 예후에 있어서 가장 큰 영향을 보임을 알 수 있었으며 이러한 소견을 보인 환자는 보다 적극적인 보조치료가 필요하리라 사료된다. Purpose : The adjuvant postoperative radiotherapy has been usually applied to the patients with unfavorable prognostic factors after radical operation in early cervical cancer. We focused on the evaluation of the survival status and failure patterns of the patients with postoperative radiotherapy. Materials and Methods : We retrospectively analyzed ninety patients with FIGO stage IB and IIA cervix cancer who received postoperative pelvic irradiation at Chonnam University Hospital between August 1985 and December 1988, Seventy-eight patients had adequate follow-up information for survival analysis. Median follow-up time of these patients was 64 months. Results : The 5 year overall and disease free survival rate of ninety patients was $80.0\%$ and $80.2\%$, respectively. The prognostic significance to the survival was determined by multivariate analysis. Adequacy of resection margin(p=0.005) and lymph node status(p=0.005) appeared to be independent prognostic factors. Recurrence occurred in 13 patients, 5 in the pelvis and 8 at distant sites. The median time to recurrence was 19 months(range:3-39 months). The pelvic recurrence was more prevalent in the group of patients with adenocarcinoma, depth of stromal invasion more than 10mm and use of chemotherapy. The distant failure was more prevalent in the group of positive resection margin or positive lymph node with statistical significance. Conclusion : Patients with pelvic lymph node or surgical margin involvement clearly constitute a high risk group in this analysis and should be considered as candidates for some form of adjuvant therapy.

Objective: The aim was to assess the value of resistance index(RI) and pulsatility index(PI) to differentiate between benign and malignant ovarian tumors by color and pulsed Doppler ultrasound. Methods: 129 ovarian tumors identified with ultrasound were referred for color and pulsed Doppler ultrasound evaluation to calculate the lowest RI and PI, and the corresponding histopathologic diagnosis was recorded. Results: The intratumor artery waveforms were obtained in 37.1%(36 of 97) of benign tumors and in 91.0%(29 of 32) of the malignant group. RI and PI were lower in malignant tumors than in benign tumors(p<0.01). Also, there was a significant incremental decrease in both indices value from the benign tumor toward borderline malignancy(p<0.05) and to invasive ovarian cancer(p<0.01). But, there was no significant difference in both indices value according to the FIGO stage of ovarian malignancy. For RI cut-off value of 0.6, sensitivity and specificity were 89.7% and 91.7%; for PI cut-off value of 1.1, 86.2% and 91.7%. Therefore, the most accurate cut-off values of RI and PI were 0.6 and 1.1, respectively. Conclusion: RI and PI calculated by color and pulsed Doppler ultrasound can help in the diagnosis and selection of treatment plan of ovarian tumors, especially when the morphological finding of ovarian tumor is equivocal. And during the follow up of benign tumors, both indicies can give us the clue of malignant potential of benign tumors.
