The efficacy of concurrent cisplatin and 5-flurouracil chemotherapy and radiation therapy for locally advanced cancer of the uterine cervix / 부인종양

OBJECTIVE: To evaluate the efficacy of concurrent chemoradiation (CCRT) using 5-flurouracil (5-FU) and cisplatin for locally advanced cervical cancer. METHODS: We reviewed the medical records of 57 patients with locally advanced cervical cancer (stage IIB-IVA and bulky IB2-IIA tumor) who underwent the CCRT at Dong-A University Hospital from January 1997 to June 2007. The CCRT consisted of 5-FU, cisplatin and pelvic radiation. Every three weeks, 75 mg/m(2) cisplatin was administered on the first day of each cycle and 5-FU was infused at the dose of 1,000 mg/m(2)/d from the second day to the fifth day of each cycle. Radiation was administered to the pelvis at a daily dose of 1.8 Gy for five days per week until a medium accumulated dose reached to 50.4 Gy. If necessary, the radiation field was extended to include paraaortic lymph nodes. Consolidation chemotherapy was performed using 5-FU and cisplatin. RESULTS: Fifty-seven patients were enrolled and the median follow-up duration was 53 months (range 7-120 months). The overall response rate was 91.5% (74% complete response and 17.5% partial response). The 5-year overall survival and 3-year progression free survival rates were 69.4% and 74.9%, respectively. During the follow-up period (median 23 months, range 7-60 months), fourteen patients were diagnosed as recurrent disease. CONCLUSION: CCRT with 5-FU and cisplatin which is the primary treatment for patients with locally advanced cervical cancer was effective and well tolerated.

A Case of Ovarian Mucinous Borderline tumor in Postoperatively Diagnosed Dermatomyositis accompanying Colon Cancer / 대한산부인과학회지

Dermatomyositis is rare inflammatory condition of the skin and muscles that the incidence is 5 cases per million population per year. This disease was strongly associated with malignant disease, particularly ovarian, lung, pancreatic, stomach and colorectal cancers, and non-Hodgkins lymphoma. A 56-year-old female patient had a ovarian tumor, thereafter she presented with typical skin lesions and muscle weakness. And then we found she had a colon cancer. Here we present the case with brief review of literature.

A Case of Premature Ovarian Failure in Patient with Unbalanced translocation on the X chromosome / 대한산부인과학회지

Premature ovarian failure (POF) is defined as the complete cessation of menses less than 40 years of age. The criteria are more than four months of amenorrhea, with serum follicle stimulating hormone value of >40 mIU/mL and the frequency of POF is about 1% of all women. Although the etiologies of POF remain unknown, suggested factors are genetic, autoimmune, chemotherapy and environmental toxicants. The cytogenetic abnormalities predominantly concern the X chromosome, including Turner syndrome, Fragile X syndrome and deletion or translocation of X chromosome. We report a case of premature ovarian failure with the following karyotype: 46,X,der(X), t(X;11)(q28;p13).

Analysis of prognostic factor and survival in patients with epithelial ovarian cancer treated with combination chemotherapy / 부인종양

OBJECTIVE: The purpose of this retrospective study is to identify and to discuss the clinical relevance of prognostic factors and survival rate in patients with epithelial ovarian cancer treated with combination chemotherapy. METHODS: A total of 98 histologically verified patients with epithelial ovarian cancer who were treated at Dong-A Medical Center between 1997 and 2002 were used for analysis. The 30 patients having borderline tumor were excluded. Kaplan-Meier survival curves were computed and tested statistically by the log rank test. A multivariable Cox proportional hazard model was applied to access the prognostic significance of the different covariates. RESULTS: The median age of the patients with epithelial ovarian cancer was 46.6 years and FIGO stage distribution was 38.2% for stage I, 5.9% for stage II, 44.1% for stage III, 11.8% for stage IV. The histopathologic type distribution were serous type (45.6%), mucinous type (36.8%), endometriod type (8.8%), clear cell type (7.4%), mixed type (1.4%). Residual tumor volume size of less than 1 cm or 1 cm was identified in 50 patients (73.5%) and more than 1 cm in 18 patients (26.5%) after primary cytoreductive surgery. The overall 5-year survival rate was 55.7%. According to univariate analysis, FIGO stage (p<0.0001), residual volume (p<0.0001), ascitic fluid volume (p=0.0001), menopause (p=0.0021), CA125 (p=0.0058), tumor size (p=0.0099), age (p=0.0113) were significant prognostic factors affecting survival. However, multivariate analysis in this study demonstrated that FIGO stage (p=0.011), residual tumor volume (p=0.026), ascitic fluid volume (p=0.031) were found to be the most significant independent prognostic factors. CONCLUSION: In this retrospective study, the overall 5-year survival rate of patients with epithelial ovarian cancer treated with combination chemotherapy was 55.7% and 5-year survival rate of stage I/II was 95.8%, stage III 28.4%, stage IV 0%. The overall survival of stage I/II were 90 months, stage III 39 months, stage IV 17 months. In multiple analysis, FIGO stage, residual volume, ascitic fluid volume were identified as three most significant independent prognostic factors.

Cytogenetic Analysis in 785 Cases of Midtrimester Amniocentesis Using In Situ Coverslip Culture / 대한산부인과학회잡지

OBJECTIVE: Amniocentesis is the most commonly used invasive method for prenatal diagnosis of genetic disorders. We performed this study to analyze the indications, distributions of maternal age and cytogenetic results of midtrimester amniocentesis. METHODS: We retrospectively analyzed 785 cases of midtrimester prenatal genetic amniocentesis which were performed in the cytogenetics laboratory using in situ coverslip culture at Dong-A University Hospital from January 1995 to March 2003. RESULTS: Amniocentesis was practiced mostly from 15 weeks to 20 weeks of gestational ages. Requested indications of amniocentesis were abnormal maternal serum screening (421, 53.7%), advanced maternal age (233, 29.7%) and abnormal ultrasonographic finding (61, 7.8%) in the order of decrease. The overall incidence of chromosome abnormalities was 5.1% (40 cases), and it contains 27 cases (3.4%) of numerical abnormalities and 13 cases (1.7%) of structural abnormalities. Among autosomal abnormalities Down syndrome was most common (13 cases) and followed by Edward syndrome (2 cases). Of the sex chromosomal abnormalities, three cases of Turner syndrome and three cases of Kleinefelter syndrome were found. Chromosomal abnormalities were most frequently noted in the maternal age of 30 to 34 years old (14 cases, 35.0%), 25 to 29 years old (12 cases, 30.0%), followed by 35 to 39 years old (7 cases, 17.5%). The frequency of pseudomosaicism were 5 cases (0.6%). CONCLUSION: Maternal serum screening, advanced maternal age and antenatal ultrasonographic finding must be important screening methods for amniocentesis which is considered to the most effective diagnostic procecdure for prenatal cytogenetic studies. I conclude that the karyotyping analysis of midtrimester amniocentesis is efficacious method for detection of chromosomal aberration and genetic counselling for parents.

Three cases of Twin-to-Twin Transfusion Syndrome which were managed with maternal digitalization / 대한산부인과학회잡지

Twin-to-twin transfusion syndrome (TTTS) is one of the complications showing high mortality rate in monochorionic twins with vascular communication in the placenta. Clinical manifestations of TTTS are usually characterized by polyhydramnios, circulatory overload, cardiac failure and fetal hydrops in the recipient twin and symmetrical fetal growth restriction, oligohydramnios, hypovolemia and anemia in the donor twin. TTTS occurres in 10-35% of monochorionic twins. We report three cases of TTTS with fetal hydrops in which amnioreduction was serially attempted and maternal digoxin treatment was tried for the therapeutic purpose.

A Case of Vulvar Glassy Cell Carcinoma / 대한산부인과학회잡지

Vulvar glassy cell carcinoma (GCC) is a very rare neoplasm. Although GCC is considered to be a poorly differentiated variant of adenosquamous carcinoma, its real nature is still debatable. We report a case of GCC of the vulva in a 53-year-old woman and review the literatures. The patient had bleeding from the lesion of the vulva and pelvic MRI revealed left inguinal lymph node enlargement. Histologically a cytoplasm of ground glass appearance was observed with a distinct cell wall and large nucleus containing prominent nucleoli. The clinical stage of the tumor was III as classified by the International Federation of Gynecology and Obstetrics (FIGO). She was treated by a left hemivulvectomy and bilateral inguinal lymphadenectomy and followed by external irradiation to the pelvis and left inguinal area. The patient was still alive without evidence of disease after 12 months treatment.

Partial Trisomy 10q from Maternal Balanced Insertion (15;10)(q22;q22q24) / 대한산부인과학회잡지

A balanced insertion of a parent may produce normal or carrier offsprings, spontaneous abortions, and chromosomally unbalanced offsprings. This is a rare report of duplication of chromosome 10q22->q24 which has arisen through the segregation of a balanced direct insertion. The partial trisomy 10q is a specific syndrome of mental retardation and malformation characterized by psychomotor delay, growth restriction, distinctive dysmorphic appearances, and, in some cases, cardiac, renal, and ocular abnormalities. We have experienced a case of partial trisomy 10q from maternal balanced insertion, which was prenatally showed severe fetal growth restriction and oligohydramnios, and present it with a brief review of literatures.

A Case of Cushing's Syndrome in Pregnancy Secondary to an Adrenal Cortical Adenoma

Cushing's syndrome in pregnant women is rare and difficult to be diagnosed because of the syndrome's association with oligomenorrhea or amenorrhea and the changes in cortisol metabolism during normal pregnancy. Cushing syndrome in pregnancy is usually confused with complicated pregnancy, such as preeclampsia or gestational diabetes, and its rarity leads to a low degree of clinical suspicion, often delaying diagnosis. We experienced a case of Cushing's syndrome in pregnancy, which had been considered as the severe preeclampsia and gestational diabetes due to uncontrolled hypertension and hyperglycemia. The pregnancy was terminated with an emergency cesarean operation at 30 weeks of gestation because of severe preeclampsia. In consequence of the evaluation about the Cushing's syndrome after delivery, the adrenal cortical adenoma of right adrenal gland was diagnosed and laparoscopic adrenalectomy was performed.

Prenatal Diagnosis of Recurrent Trisomy 18 Syndrome / 대한진단검사의학회지

Though data on the recurrent risk after the birth of one fetus or infant with trisomy 18 is sparse, it has been presumed that the recurrence risk would be lower than the 1% for full trisomy 21 syndrome cases. We report a rare recurrent trisomy 18 found in amniocentesis in a family in which both parents had normal blood karyotype. Molecular analysis was undertaken in the second episode of trisomy 18 and a maternal meiosis II nondisjunction error was diagnosed.

The Changes of Serum Nitric Oxide and Platelet Activating Factor Concentrations in Preeclampsia / 대한산부인과학회잡지

OBJECTIVE: The aim of this study is to determine whether any association exists between preeclampsia and the maternal serum level of nitric oxide (NO) and platelet activating factor (PAF). METHODS: NO concentrations were measured using Stuehr's method and PAF concentrations were measured with [3H]PAF scintillation proximity assay (SPA) system (Amersham Pharmacia Biotech). Data were analyzed with SAS windows version 6.12, with significance established at p<0.05. RESULTS: The mean (+/-SD) maternal serum concentrations of NO were significantly higher in the group with severe preeclampsia (5.535+/-0.343 ug/ml) and mild preeclampsia (5.891+/-0.481 ug/ml) than in the normotensive pregnancy group (2.036+/-0.744 ug/ml) (p<0.05). The mean (+/-SD) maternal serum concentrations of PAF were significantly higher in the group with severe preeclampsia (928.9+/-32.3 ng/ml) and mild preeclampsia (789.1+/-63.9 ng/ml) than in the normotensive pregnancy group (435.8+/-59.5 ng/ml) (p<0.05). The mean birth weight was lower in the mild and severe preeclampsia groups than in the normotensive pregnancy group (p<0.05). CONCLUSION: Maternal serum NO and PAF concentrations were more increased in preeclampsia than normotensive pregnancy group. NO may therefore serve as compensatory mechanism for vasoconstriction of preeclampsia and PAF as a marker for the risk of preeclampsia.

A Case of Multiple Placental Chorioangioma Combined with Oligohydramnios / 대한산부인과학회잡지

Chorioangioma is the most common benign tumor of the placenta and associated with adverse perinatal outcome. The prevalence of chorioangioma of the placenta is about 1 percent. The most placental chorioangioma has no clinical significance. But the uncommon large (greater than 5 cm in diameter) chorioangioma may produce both maternal and fetal complications, such as polyhydramnios, preterm labor, fetal heart failure, hydrops fetalis, fetal growth restriction, fetal microangiopathic hemolytic anemia, fetal thrombocytopenia, toxemia of pregnancy, maternal thrombocytopenia, and maternal coagulopathy. The ultrasonography and Color Doppler are used for diagnosis of these lesions. If chorioangioma is suspected, Color Doppler study is informative to confirm the presence of the vascular channels. We report a case of multiple chorioangioma combined with oligohydramnios and discuss the noxious effects of this benign tumor on the mother and the fetus.

A Case of Spontaneously Regressed Hyperreactio Luteinalis Occurred in Normal Pregnancy / 대한산부인과학회잡지

Hyperreactio luteinalis rarely occurs in normal single pregnancy. About 50 such cases have been published. It is usually occurs in trophoblastic disease. This case is a huge hyperreactio luteinalis that detected in gestational age 16 weeks. The patient delivered a normal female infant at 41th week of gestation without any mass related problems. The hyperreactio luteinalis was a benign condition in itself with normal spontaneous remission in two months after delivery. Also the level of elevated human chorionic gonadotropin became normal. The conservative management was appropriated. This case is noteworthy because it resulted in spontaneous regression without surgical intervention and conserved ovarian tissue.

Detection of fetal erythroid cells from maternal blood using fluorescence in situ hybridization and liquid culture

Fetal nucleated erythrocytes circulating in maternal blood are a potential source of fetal DNA for noninvasive prenatal genetic diagnosis. However, the estimated ratio of fetal to maternal cells is extremely small. In order to enrich these cells, we performed direct culture using a two-phase liquid system. Mononuclear cells were obtained from maternal blood samples at 8-10(+3) weeks of gestation and cultured in the first phase. After 4-5 days, the nonadherent cells were harvested and recultured with erythropoietin in the second phase for another 3-5 days. We examined cellular morphology, and counted the number of benzidine- positive cells and the percentage of glycophorin A/CD71 positive erythroid cells. We also did Kleihauer-Betke stain for Hb F, polymerase chain reaction (PCR) for SRY/DYZ1, chromosome analysis, and fluorescence in situ hybridization (FISH). The number of total erythroid cells reached about 0.1x10(6)-1.0x10(6)/mL with a purity of 84.0-97.3%. Hb F stain showed total erythroid cells of approximately 0.4x10(4)-9.8x10(4)/mL. Male DNA was detected in one case by PCR. In this case, the XY karyotype was confirmed by FISH and amniocentesis. This approach provides enriched source of fetal cells for further prenatal genetic analysis without complicated separation or sorting procedures.

Obstetrical Outcomes of Increased Nucleated RBC in Maternal Blood during Early Pregnancy / 대한산부인과학회잡지

OBJECTIVE: During early pregnancy, CD71 and glycophorin A positive cells in peripheral blood of pregnant women were studied, to assess the relationship between increased numbers of nucleated RBC (NRBC) in maternal blood and pregnant outcomes. METHODS: Peripheral venous blood samples were obtained from 47 primigravidas of 14~16 weeks gestation. Triple screening tests were routinely performed. Blood samples were incubated with monoclonal anti-CD71 and monoclonal anti-glycophorin antibodies, and analyzed by flow cytometry using FACSort (Becton Dickinson, USA) for checking the NRBC count. RESULTS: A total of 47 pregnant women were enrolled at 14-16 weeks gestation; one pregnancy had anemia and was excluded from the test, the outcome was unknown for 2 other pregnancies, and twelve pregnancies had 1-4% of NRBC in the maternal blood. In the remaining 32 pregnant women, grouped according to their percentage of NRBC, the group with more than 4% of NRBC was termed the study group, and less than 1% of NRBC was termed the control group.The results were as follows: 1) The study group showed lower fetal birth weight than the control group, which was statistically negatively significant (y=-62.219x + 3,401.6, R2=0.2146, p0.05).3) There were two complications in the study group: one was a preterm delivery at 35 weeks of gestational age with birth weight of 2,300 gm and the other was a case of pregnancy-induced hypertension. CONCLUSION: It can be concluded that increased NRBC count in maternal blood during the early second trimester has a significant correlation with fetal birth weight but can't predict high risk pregnancies such as preeclampsia, preterm labor or intrauterine fetal growth restriction.In order to obtain a higher predictive value, further studies with more participants and with high risk pregnancies of known risk factors are needed.

Recurrent Partial Trisomy 1q in Maternal Balanced Translocation t(1;11)(q32;q23) / 대한산부인과학회잡지

Abnormal offsprings from balanced translocation carriers usually inherit only one of the translocated products and are therefore partially trisomic for one chromosome and partially monosomic for another. Partial trisomy 1q usually demonstrates fetal growth restriction and anomalies of head, face, urogenital tract, heart, finger and toes with a wide range of characteristics and severities. It has been reported in a few individuals in the world and this is the first report of partial trisomy 1q in Korea. We present the case of recurrent partial trisomy 1q in maternal balanced translocation which was prenatally diagnosed by amniocentesis with fluorescence in situ hybridization(FISH) based on abnormal ultrasonographic findings and poor obstetric history.

A Case of the HELLP Syndrome treated with Postpartum Plasmapheresis / 대한산부인과학회잡지

Plasmapheresis has been used for some conditions during pregnancy and puerperium, such as hemolysis, elevated liver enzymes, and low platelet (HELLP) syndrome. We present one case of the HELLP syndrome which was treated with plasmapheresis and also review the indications, complications and guidelines for repetitive plasma exchange.

Detection of a Familial Y/l5 Translocation by FISH, G-Banding, C-Banding, and Ag-NOR Stain / 대한임상병리학회지

Prenatal chromosome analysis of amniotic cells at 18 weeks of gestation showed a male fetus to carry a large 15p+ derivative chromosome inherited from his mother. Extra genetic material on the short arm of chromosome IS was silver-negative with Ag-NOR (nucleolus organizer regions) stain, but stained darkly with C-banding method like the distal heterochromatic segment of the Y long arm. Fluorescence in situ hybridization (FISH) using two DNA probes (DYZ1 and D15Zl) showed a red fluorescent signal on 15p+ In addition to a green chromosome 15 centromere signal, confirming 15p to be from the distal Yq heterochromatin.

A Case of Ovarian Mucinous Cystadenocarcinoma with Mural Nodule of Anaplastic Carcinoma / 대한부인종양콜포스코피학회잡지

Mural nodules in ovarian mucinous tumors, whether benign, borderline, or malignant, have been described by several authors since Prat and Scully first described sarcoma or sarcoma-like mural nodules occurring in association with mucinous epithelial neoplasia in 1979. Three distinct types of the mural nodule have been identified; i. e., 1) sarcoma-like lesion, 2) true mesenchymal sarcome, and 3) anaplastic carcinoma simulating a sarcoma. Mural nodules of sarcomatous and carcinomatous foci associated with mucinous ovarian tumors should be separated from sarcoma-like nodules because of the poor prognosis of the former compared to the favorable prognosis of the latter. We experienced a case of ovarian mucinous cystadenocarcinoma with sarcoma-appearing mural nodule of anaplastic carcinoma occurred in a 59-year-old woman and reported with brief review of the literatures.
