OBJECTIVE: To investigate the response of hyperplastic endometrium to Medroxyprogesterone acetate according to the histologic types such as simple typical, complex typical and atypical hyperplasia. METHODS: A total of 79 patients with histologically proved endometrial hyperplasia were enrolled into this prospective study between March 1996 and May 1998. Patients without atypia were placed on a regimen of cyclic therapy with 10mg MPA orally, each day for 14days per month for 3 months. In the cases in which hyperplasia did not regress , MPA was increased to 20mg. Patients with atypical hyperplasia received continuous MPA therapy, 20mg orally each day for 3 month. All patients were followed up for a minimum of 3 months and a maximum of 1 year(mean 7 months). RESULTS: In patients with simple typical hyperplasia, 45 patients(80.4%) had regression, 11 patients(19.6%) had persistence and none had progression. In patients with complex typical hyperplasia, 10 patients(83.3%) had regression, 2 patients(16.7%) had persistence and none had progression. But, in patients with atypical hyperplasia 5 patients(45.4%) had regression, 4 patients(36.4%) had persistence and 2(18.2%) patients had well differentiated endometrial adenocarcinoma. There was no recurrence during the follow up. CONCLUSION: This data suggest that most women with typical hyperplasia respond to progestin therapy, but there is high failure rate of response to progestin therapy and risk of endometrial cancer in patients with atypical hyperplasia. If the young patient desires to preserve her fertility, then progestin therapy may be considered as primary treatment in patients with atypical hyperplasia. But older patients in whom fertility is not an issue, hysterectomy should be selected as treatment of choice for atypical lesion.

We report a case of cerebral lymphomatoid granulomatosis in a 50-year-old man. Lymphomatoid granulomatosis is an unusual condition which usually presents as a pulmonary manifestation, which occasionally affects the brain, and causes focal inflammatory lesions. Primary cerebral lymphomatoid granulomatosis is very rare. We describe a case of lymphomatoid granulomatosis in the left frontal lobe without pulmonary involvement.

OBJECTIVE: The object of this study was to compare the diagnostic accuracy of a sonographic morphologic scoting system, the serum CA-125 assay, and a combination of both in patients undergoing laparotomy for a clinically diagnosed adnexal mass. METHODS: In 129 consecutive patients, the morphology of the mass was evaluated and scored by the morphologic scoring system of Sassones using transabdominal or transvaginal sonography and blood samples were obtained for CA-125 assay before planning surgery, RESULTS: The sensitivity of the sonographic morphologic scoring system was 90.6%, the specificity 84.5%, the positive predictive value 65.9%, and the negative predictive value 96.5%, compared with 68.8, 77.3, 50.0, and 88.2% for CA-125 and 96.9, 66.0, 48.4, and 98.5% for the two tests combined, respectively. Only one case of serous borderline ovarian tumor was missed when the two tests were combined. The sensitivity and mean value of the serum CA-125 increased with the stage of ovarian cancer. CONCLUSION: The combination of sonographic findings with a serum CA-125 assay was more sensitive, but less specific, than sonography or the serum CA-125 assay alone in predicting the malignancy of an adnexal mass. The serum CA-125 level generally reflected the stage of the disease. We think that it is reasonable to check the serum CA-125 only in cases of ovarian malignancy diagnosed by sonography.

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.

OBJECTIVE: This study was designed to evaluate the efficiency of tumor markers level for early diagnosis of ovarian malignancy and for differentiation between benign and malignant ovarian tumors. MATERIALS AND METHODS: We determined preoperative serum tumor markers level in patients who were going to have an operation due to ovarian tumor in OB & GY Dept. of Chonnam University Hospital from April 1993 to September 1999. RESULTS: 1) The average values of serum tumor markers in patients with malingnant ovarian tumors were statistically higher than those of benign ovarian tumors. among malignant ovarian tumors, positive rate of all serum tumor markers was highest in epithelial ovarian carcinoma group. and among ovarian tumor markers, and positive rate of CA 125 was highest in epithelial ovarian carcinoma. 2) Dermoid cyst and endometioma were correlated to CA 19-9, CA 125 levels respectively. for malignant tumors, mucinous ovarian adenocarcinoma and non-mucinous ovarian adenocarcinoma were CA 19-9, CA 125 levels respectively. 3) Among ovarian tumor markers, CA 125 was the most in sensitivity and CA 72-4 was the most in specificity and diagnostic efficiency. 4) For postmenopausal women with ovarian tumors, elevated levels of at least one of the 4 tumor markers were present in the serum in 85.7% of the women who developed cancer, 62.5% of women with borderline, 27.8% of women with benign ovarian tumors. Conclusion; It is suggested that determination of serum tumor markers in patient suspected of ovarian tumor may be helpful to clinician for early diagnosis, differentiation between malignant and benign ovarian tumors.

Magnetic resonance imaging(MRI) appears to be the most sensitive modality for early diagnosis of avascular necrosis of the femoral head and has recently been recommanded as a means of strengthening individual treatment decisions, However, MR signal patterns in AVN has been described to vary widely. And the understanding of the anatomic and pathologic structures represented on the MRI thus appears desirable for improved tissue characterization, staging of disease, and therapeutic planning. The object of this study was to analyze the correlation of MRI, radiographic staging, radionuclide imaging, and histological findings in AVN of the femoral head. The authors analyzed retrospectively 30 patients(36 hips) of AVN of the femoral head who underwent bipolar hemiarthroplasty or total hip replacement arthroplasty at Korea University Hospital from Nov. 1990 to Oct. 1993. The radiographic stage was evaluated according to Ficat and Arlet classification, and MRI was evaluated according to Mitchell et al. classification. The histologic changes corresponding to MRI abnormalities were assessed in 10 fresh surgical specimens. The obtained results were as follows; 1. Nine cases (25%) were class A, 3 class B (8%), 6 class C (17%) and 18 class D(50%) by Michell et al. classification on MRI and typical double line sign was found in 20 cases(56%). 2. Most of the cases of Ficat and Arlet stage II in simple radiograph showed MR class A or B, and stage III and IV showed class C or D. 3. There cases(10%) showed false negative studies in radionuclide imaging. 4. The necrotic bone & marrow and amorphous cellular debris represented the low signal intensity on both T1WI and T2WI, and repairing tissue, thickened trabeculae with mesenchymal cell infiltration was low signal intensity in T1WI and intermediate signal intensity in T2WI, and fibrous tissue was low signal intensity on both T1WI and T2WI. 5. MR classification by Mitchell et al. was not correlated with histological finding in respect of progression. Above results suggest that MRI provide the information about accurate anatomical location and involved site of necrosis, while MR classification by Mitchell et al. was not useful for staging of pathogenic process of AVN of the femoral head. The therapeutic plan and modalities have to be estabilished by comprehensive analysis of MRI, simple radiograph and other diagnostic modalities.

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.
