Placental site trophoblastic tumor(PSTT) is a very rare form of gestational trophoblastic disease; weencountered two cases. MR imaging of the first patient revealed a solid uterine mass, slightly hyperintense tonormal myometrium on T1-weighted images and hyperintense on T2-weighted images. After intravenous gadoliniuminfusion, the mass was more enhanced than normal myometrium, and PSTT was confirmed pathologically after totalhysterectomy. In the second patient, PSTT was proven pathologically after laparoscopic left adnexectomy and wedgeresection of the right ovary. Postoperative enhanced CT scans revealed a well-enhanced right ovarian mass andextensive metastasis to the liver, pancreas, both adrenals, the stomach, lung and brain, but no mass was detectedin the uterus. Many of these metastatic lesions were infiltrating low density masses associated with highlyenhanced tubular or serpiginous structures, while some were of very high density.

The purpose of this study was to investigate the feasibility of sentinel node frozen biopsy to minimize the extensive pelvic lymph nodes dissection in early stage cervical cancer patients on the basis that the risk of skip metastasis to the paraaortic area is negligible. Twenty-six patients with early stage cervical cancer were enrolled in this study. Technetium-99m colloid albumin (Tc(99m)) was injected intradermally around the tumor for allowing preoperative lymphoscintigraphy and intraoperative hand-held gama probe detection of seninel nodes. For visual detection, isosulfan blue dye was injected into the peritumoral sites before peritoneal opening. Postoperative morbidity and negative predictive value were the endpoints of this study. The 26 patients, ranging in age from 32 to 71 yr, underwent intraoperative sentinel nodes mapping. All the patients underwent complete pelvic lymph nodes dissection including para-aortic nodes. There was one case with positive non-sentinel nodes despite the negative sentinel node by frozen biopsy (negative predictive value, 95.2%). This new technique of sentinel node mapping is safe and simple to perform. Further clinical trials using the combination of Tc(99m) and isosulfan blue dye are warranted and this technique will make a true advance for less aggressive management of patients with early stage cervical cancer.

OBJECTIVE: Epithelial ovarian cancer is the most common cause of death due to gynecologic malignancies in adults, but is rare in children and adolescents. This is a report of series of such patients under 20 years of age documenting their presentation, histologic type, stage of disease, treatment, and outcome. METHODS: We collected data on 21 patients with epithelial ovarian cancer under 20 years of age between January 1990 and December 2005. Patient records and pathology were reviewed. RESULTS: Epithelial ovarian cancer under 20 years of age was 2.2% in overall ovarian cancer. Epithelial ovarian cancer was 42.0% among 50 patients under 20 years of age and the most common histologic type was germ cell tumors (54%). The median age at the time of diagnosis was 17.6 years (range, 13-20 years), and the median follow-up was 87 months (range, 4-175 months). There were seventeen (81.0%) mucinous tumors, four (19.0%) serous tumors. About thirty-eight percent were low malignant potential or borderline tumors. About Eighty-five percent (18 patients) of tumors were stage I disease and about fourteen percent (3 patients) were stage III disease at the time of diagnosis. Surgical treatment included conservative surgery in 18 patients (85.7%), total abdominal hysterectomy and bilateral salpingo- oophorectomy in 3 patients (14.3%). CONCLUSION: Epithelial ovarian cancers are rare in patients in children and adolescents. The majority of ovarian cancers in this age group are mucinous tumors, stage I at diagnosis and borderline ovarian tumor. Conservative management is feasible to achieve preservation of fertility.

Cervical carcinoma is the second leading cause of death from cancer in women worldwide. It is well known that human papillomaviruses (HPVs) is the etiologic agent of cervical neoplasia and cervical cancer. Zinc has been shown to inhibit the growth of malignant cell lines by inducing apoptosis and cell cycle arrest. Recently it was reported that zinc-citrate compound (CIZAR(R)) has a cytotoxic effect on choriocarcinoma cell line and ovarian adenocarcinoma cell line and suppresses its proliferation inducing apoptosis. CIZAR(R) prevents the proliferation by inactivation of m-aconitase activity and induces apoptosis by increasing Bax expression and reducing Bcl-2 expression and inactivation of telomerase. We report one patient of cervical adenocarcinoma with HPV infection, who desires to continue pregnancy, treated by daily topical application of SeLava(R) which contains zinc-citrate compound (CIZAR(R)). We followed up the cytologic, pathologic and coloposcopic changes of healing process.

OBJECTIVE: Conization is used for diagnosis and treatment of cervical neoplasia. Our purpose of this investigation is to determine the efficacy of loop conization for the treatment of cervical dysplasia and the significance of the clinical and histological factors used to predict residual dysplasia after loop conization. METHODS: We reviewed the charts of patients who were received conization and subsequently total hysterectomy at Kangnam St Mary Hospital during 1989 and 2000. Logistic regression and Chi-square test were used for analysis. RESULTS: Total 257 patients were included. The mean age of the patients was 44.7 years. Of these patients, 87 (33.8%) had residual disease in the hysterectomy specimens. Age, the involvement of cut surface of endocervix and exocervix, severity and extent of the lesion, and scattering lesion were associated with the residual disease. But preoperative HPV infection, which is known as the cause of cervical neoplasia was not associated with the residual disease. CONCLUSION: When the high risk factors are present, the validity of conservative treatment should be considered and more careful follow up with pap smear, HPV test and colposcopy is necessary. Because about one thirds of patient has residual disease after conization, LEEP conization should be used for diagnosis of cervical neoplasia rather than treatment.

The purpose of this study was to evaluate the significance of telomerase activity in gestational trophoblastic disease and the association of telomerase activity in complete hydatidiform mole and subsequent development of persistent gestational trophoblastic tumor. By using the standard telomerase repeat assay, we examined telomerase activity in 2 normal placentas, 31 complete hydatidiform moles, 7 invasive moles, 5 choriocarcinoma tissues and choriocarcinoma cell line (JEG-3). Telomerase activity was detected in 13 of 15 (86.7%) complete hydatidiform mole patients who eventually had chemotherapy for the treatment of persistent gestational trophoblastic tumor. All of the 9 patients with metastatic disease (FIGO Stage III) had telomerase activity in their initial molar tissue. In contrast, telomerase activity was evident in only two of 16 (12.5%) complete hydatidiform mole patients with spontaneous remission. While telomerase activity was not detected in normal placentas, high level of telomerase activity was detected in all of 7 invasive moles, 5 choriocarcinoma tissues and choriocarcinoma cell line (JEG-3). The presence of telomerase activity in a complete hydatidiform mole is associated with the development of persistent gestational trophoblastic tumor, such as invasive mole and choriocarcinoma.

OBJECTIVE: Human seminal plasma has diverse biological activities including cytotoxic effect. It contains high concentrations of zinc and citric acid. Zinc inhibits several carcinoma cell growths through induction of cell cycle arrest and apoptosis. We tried to investigate the effects of zinc-citrate compound (CIZAR(R)) on normal human ovarian epithelial (NOSE) cells and human epithelial ovarian cancer cells, OVCAR-3. METHODS: To investigate the potential effect of CIZAR(R) on cell growth and survival, cells were treated with different dose and exposed to different time. Mitochondrial(m)-aconitase activity was determined in cell extracts using aconitase assay. The flow cytometric assay, DNA laddering, telomerase activity and morphological analysis were done to investigate apoptosis of OVCAR-3 cells. Molecular mechanism of apoptosis was investigated by p53, Bcl-XL, Bcl-2, Bax protein, and caspase activity. RESULTS: Treatment of OVCAR-3 cells with CIZAR(R) resulted in a time- and dose-dependent decrease in cell number in comparison with NOSE cells. M-aconitase activity was significantly decreased in OVCAR-3 cells but relatively constant in NOSE cells. The flow cytometric assay, DNA laddering and morphological analysis indicated apoptosis of OVCAR-3 cells. CIZAR(R) did not affect p53 but increased the expression of p21waf1 upon the indicated times and induced reduction of telomerase activity. CIZAR(R) reduced expression of Bcl-2 and Bcl-xL proteins but induced expression of Bax protein. CIZAR(R) induced apoptosis of OVCAR-3 cells by activation of caspase-3 pathway. CONCLUSION: These results show that CIZAR(R) prevent the proliferation of OVCAR-3 cells by inactivation of m-aconitase activity and induce apoptosis by induction of apoptotic genes and repression of antiapoptotic genes without adverse effect on normal ovarian epithelial cells. These results will offer new window in prevention and treatment of epithelial ovarian cancer.

For evaluating the reproductive performances of GTD patients, we found 115 cases of GTD patients, 77 HM and 38 GTT, who became pregnant after the completion of treatments and follow-up period. The results of this study suggest subsequent pregnancies after the completion of treatments may promise normal reproductive outcomes regardless of the chemotherapy.

OBJECTIVE: We assessed the prognostic factors and the efficacy of adjuvant therapy and reviewed randomized studies carried out on patients receiving adjuvant therapy with early endometrial carcinoma. METHODS: One hundred and five patients that received primary surgical treatment for stage IB, IC and II endometrial cancer were enrolled in this study. The clinical outcomes were compared among the patients with variable prognostic factors and adjuvant treatments. RESULTS: One hundred and five patients fulfilled the eligibility criteria and 46 patients (43.8%) underwent adjuvant therapy. Disease recurrence occurred in nine patients within a median time of 24 months. Cervical involvement was an independent prognostic factor for the disease-free survival rates. Eight of 16 patients with FIGO stage II disease received adjuvant chemotherapy consisting of cisplatin and etoposide (or cyclophosphamide) or combined chemoradiation. The 5-year disease-free survival rate for these patients was 87.5%, a value significantly higher than for patients that received radiation therapy alone (30%). CONCLUSION: Adjuvant chemotherapy or combination chemo-radiotherapy might be superior to radiation therapy alone in high-risk early endometrial cancer patients.
