RESUMEN
Cervical pregnancy is a rare form of ectopic gestation in which the blastocyst implants in the cervical mucosa below the histologic cervical os. Because of the serious vaginal bleeding, hysterectomy was usually done in the management of cervical pregnancy. Howerver, conservative treatment is desirable for women who want to be pregnancy in the future. Methotrexate has been utilized recently for conservative management of cervical pregnancy. We report a case of cervical pregnancy which was treated succesfully with intramuscular methotrexate injection.

Hyperreactio luteinalis(HL)referes to moderate to marked cystic bilateral enlargement of ovaries due to benign theca lutein cysts, usually related to hydatidiform mole or choriocarcinoma. After its first description by Berger in 1938, almost 53 cases of HL unassociated with trophoblastic disease have been reported in the literature. We encountered one such case in a 34 years old female which was incidentally diagnosed during cesarean section at term.

Primary malignant melanoma of the vagina are believed to arise from melanocytes whichmay be present in the epithelium of the vagina.These tumors are very rare and comprise less than 0.5% of all vaginal malignancies, which are the worst prognosis compared to other malignant vaginal neoplasms. We present a case of primary malignant melanoma of the vagina with brief review ofliterature.

The nuclear accumulation of p53 protein is known to correspond with mutation of p53 tumor supressor gene. To investigate the relationsbip between clinico-pathologic features and expression of p53 mutations, 65 cases of primary cervical carcinoma were analysed by an immunohistochemieal method using monoclonal antibody of p53. Immunostaining demonstrated varioua nuclear stinings of cancer cells in 48.4% of squamous cell carcinoma(51.9% in large cell carcinoma and 25.0% in small cell carcinomas) and 23.5% of adenocarcinoma(p<0.05) No differences in clinical stage and p53 positivity were found. There was no significant correlation between p53 positive cases and status of recurrence. This data suggests that p53 protein is not correlated with the disease progression and prognosis.

226 patients with carcinoma of the uterine cervix treated with curative radiation therapy at the Department of Therapeutic Radiology, Dongsan hospital, Keimyung university, School of medicine, from July, 1988 to May, 1991 were evaluated. The patients with all stages of the disease were included in this study. The maximum and mean follow up durations were 60 and 43 months. The radiation therapy consisted of external irradiation to the whole pelvis (2700~4500 cGy) and boost parametrial doses(for a total of 4500~6300 cGy) with midline shill(4x10 cm), and combined with intracavitary irradiation irradiation(5700~7500 cGy to point A). The distribution of patients according to the stage was as follows: stage IB 37(16.4%), stage IIA 91 (40.3%), Stage IIB 58(25.7%), stage III 32(13.8%), stage IV 8 (3.5%). The overall failure rate was 23.9%(54 patients). The failure rate increased as a function of stage from 13.5% in stage 1B to 15.4% in stage IIA, 25.9% in stage IIB, 46.9% in stage III, and 62.5% in stage IV. The pelvic failure alone were 32 patients and 11 patients were as a components of other failure, and remaining 11 patients had distant metastasis only. Among the 43 patients of locoregional failure, 28 patients were not controlled initially and in other words nearly half of total failures were due to residual tumor. The mean medial paracervical(point A) doses were 6700 cGy in stage IIB, 7200 cGy in stage IIA, 7450 cGy in stage IIB, 7600 cGy in stage III and 8100 cGy in stage IV. The medial paracevical doses showed some correlation with tumor control rate in early stage of disease (stage Ib, IIA), but there were higher central failure rate in advanced stage in spite of higher paracervical doses. In advanced stage, failure were not reduced by simple Increment of paracervical doses. To improve a locoregional control rate in advanced stages, it is necessary to give additional treatment such as concomitant chemoradiation.

Thirteen patients with malignant germ cell tumars of the ovary have been treated with a combination chemotherapy. The age of the patients ranged from ll to 50 years and there was no history of radiation therapy of chemotherapy except operation, Stage distributions are as follow ; 2 pstients are stage IV, 3 are stage II and remainied 8 are stage I. 4 patients with immature teratama and 2 patients with mixed germ cell tumor received VAC chemotherapy, as primary therapy, and among them 1 lost to follow up but remained 5 cases live without evidence of disease 39 to 83 gnontha. There were 3 patients with endodermal sinus tumor and 1 received VAC and remeined 2 received FVB as primary chemotherapy, Of them 1 died of disease after 9 months of oyeration and the other 2 live now with no evidence of disease. There were 2 patiente with dysgerminoma and 2 with primary ovarian choriocarcinoma. 1 patient with dysagerminoma and 1 wit choriocarcinoma were died because of chemotherapy toxicity, 1 patient with dysgerminoma, who refused further ehemotherapy after l course of chemot.herapy, died of progressive disease. l patient wit choriocarcinoma now live well without evidence of disease at 35 months. The combination chemotherapy using VAC or PVB regimen represents an effective treatment for malignant. germ cell turnars of the ovary and reveals moderate oxicity.

To evaluate usefulness of MR in assessment of tumor response to the chemotheraphy, we prospectively studied cases of cervical carcinoma with more then 2.5cm in diameter or stage IIb or more. Three courses of chemotherapy were performed with cisplatin and 5 F-U. MR images were obtained both before and after chemotherapy. Nine of 13 patients were undertaken radical hysterectomy after chemotherapy and MR examination. MR volumetry, stage and depth of stromal invasion were compared before and after chemotherapy. And in 9 patients who underwent radical hysterectomy, comparison of pathologic and MR imaging findings were also done. @ES The results were following. @EN 1) All tumors dectrased in volume (m=80.5%). 2) Five tumors (38.5%) reduced in stage, IB→CIS(1); IIA→CIS(1), IIA→IB(2), IIB→IB(1). 3) Depth of stromal invasion in MRI correlated well with that of histo-pathologic specimen in 7 of the 9 patients. Conclusively MR imaging is useful in assessement of tumor response to chemotherapy.

Nineteen patients with previously untreated invasive squamous cell carcinoma of the uterine cervix were treated by irradiation alone at the Keimyung University Hospital from January, 1990 to July, 1991. The serial samplings of the tissue taken before and during radiation of the uterine cervix were studied by light and electron microscopic examination. Radiation-induced cellular changes, particularly nuclear degeneration was pronounced. The tumor invasion pattern remained unchanged but the number of mitosis and tumor cells decreased. The number of infiltrating inflammatory cells, multinucleated giant cells and karyolitic cells were increased with radiation. Fibrosis was also increased. Electron microscopically, the amount of tonofilament in the tissue samplings was increased in the postirradiated state, but the desmosomes were decreased in numbers. Fibroblasts began to appear after an irradiation dose of 2700cGy. After an irradiation dose of 3600cGy or more, tumor cells were nearly completely degenerated and displaced with mature fibrotic tissue. There was an increase of activated fibroblasts and collagen fibers but a decrease of inflammatory cells in the interstitial tissue. Swelling of the mitochondria and endoplasmic reticulum, loss of intercellular bridges and an increased number of secondary lysosomes were also found with radiation.
