Comparison of the AMPLICOR human papillomavirus (HPV) Test and the Hybrid Capture 2 Assay for detection of high-risk HPV / 대한산부인과학회지

OBJECTIVE: The purpose of this study was to determine the efficacy of the AMPLICOR HPV test in comparison with the Hybrid Capture 2 (HC2) test in detecting HR HPV. METHODS: One hundred and fifty-three consecutive women attending the Colposcopy Clinic were included and cervical scrape specimens were tested for the presence of 13 HR HPV genotypes by both AMPLICOR HPV test and HC2 assay. RESULTS: The prevalence of HR HPV was 53/153 (34.6%) and 52/153 (34.0%) by AMPLICOR HPV test and HC2 assay, respectively. When discordant results were observed between AMPLICOR HPV test and HC2 assay, we used the HPV genotyping DNA chip and DNA sequence analysis, as reference standards. Concordant results were obtained for 128 (83.7%) of the 153 samples (Cohen's kappa=0.63, p<0.001). The genotyping showed that no HR HPV was detected in the 10 AMPLICOR negative HC2 positive samples, while HR HPV genotype was found in 3/13 (23.1%) AMPLICOR positive HC2 negative samples. The detection rates of HR HPV with AMPLICOR HPV test and HC2 assay were 38.7% and 48.4%, respectively, in CIN1; 95.0% and 100%, respectively, in CIN3/cancer. HPV positivity of AMPLICOR HPV test and HC2 assay increased linearly with the increasing grade of cytology or histology (p<0.001). In detecting high grade (CIN2+) lesions, sensitivities were 90.9% (CI, 75.9~97.0%), 95.5% (CI, 81.9~99.0%), respectively, for AMPLICOR HPV test and HC2 assay (p=1.00). The specificities of AMPLICOR HPV test and HC2 assay were 72.7% (CI, 64.3~79.8%) and 69.3% (CI, 60.7~76.7%), respectively (p=0.75). CONCLUSIONS: AMPLICOR HPV test is comparable to HC2 assay for detection of HR HPV, with similar sensitivity and specificity in detecting CIN2+ lesions. AMPLICOR HPV test can be considered clinically useful for detection of HR HPV. However, more data are clearly needed on the performance of AMPLICOR HPV test as a screening tool.

Endometrial stromal sarcoma associated with extrauterine endometriosis: a case report and literature review / 부인종양

Endometrial stromal sarcoma (ESS) that arises from extrauterine endometriosis is a rare form of malignancy. We report the case of a 37-year-old ESS patient with extrauterine endometriosis who was treated with ifosfamide/cisplatin chemotherapy. A woman presented with epigastric pain and abdominal distension. Computed tomography imaging revealed a profuse amount of ascites, including a 12.4x12.3 cm sized posterior cul-de-sac mass composed of solid and cystic components. Cytoreductive surgery was performed to remove the mass and the histopathologic findings indicated ESS associated with extrauterine endometriosis. Six cycles of combination chemotherapy [ifosfamide (5 g/m(2)) with mesna (1 g/m(2)) and cisplatin (50 mg/m(2)) (IP)] were administered. After a six-month of disease-free interval, recurrent ESS developed in the pelvic cavity and in both lung fields. Megace medication decreased tumor marker CA-125 for six weeks. However, the patient expired sixteen months after the cytoreductive surgery. ESS associated with extrauterine endometriosis showed response to IP chemotherapy and megace.

Association of the COMT Gene Polymorphism with the Risk of PCOS in Korean Women / 대한불임학회지

OBJECTIVE: To investigate whether polymorphism of Catechol-O-methyltransferase (COMT) gene is associated with the risk of polycystic ovary syndrome (PCOS) in Korean women. METHODS: One hundred and thirty-six PCOS patients and eighty four controls were enrolled. Blood samples were collected from the patients diagnosed according to the 2003 revised criteria of the Rotterdam ESHRE/ASRM-sponsored PCOS consensus workshop group. Age matched women with regular menstruation from same geographic region were recruited as control subject. Polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) of PCR products were done to determine all individuals' genotype. RESULTS: In women with COMT(LL) genotype, there was decreased PCOS risk and this difference was statistically significant (OR 0.24, 95% CI 0.11~0.51). CONCLUSION: The results suggest that the COMT(LL) genetic polymorphism might be associated with PCOS risk in Korean women.

Association of the CYP17 gene polymorphism with the risk of PCOS in Korean women / 대한산부인과학회지

OBJECTIVE: To investigate whether polymorphism of CYP17 gene is associated with the risk of polycystic ovary syndrome (PCOS) in Korean women. METHODS: The 86 PCOS patients and 75 controls were enrolled. Blood samples were collected from 86 patients diagnosed according to the 2003 revised criteria of the Rotterdam ESHRE/ASRM-sponsored PCOS consensus workshop group. Age matched women with regular menstruation from same geographic region were recruited on the control subject. Polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) of PCR products were done to determine all individuals' genotype. RESULTS: In women with A1A1 genotype, there was increased PCOS risk and this difference was statistically significant (OR 2.2 (CI 1-4.7)). CONCLUSION: The results suggest that the CYP17 A1A1 genetic polymorphism might be associated with PCOS risk in Korean women.

Analysis of X Chromosome Inactivation in Women with Premature Ovarian Failure / 대한산부인과학회잡지

OBJECTIVE: Premature ovarian failure (POF) is a highly heterogenous condition, and its etiology remains unknown in approximately two-thirds of cases. POF can be caused by Turner syndrome, genetic disease, iatrogenic agents such as chemotherapy and radiotherapy, infection and autoimmune disease. X chromosome inactivation is the random process in females during early embryogenesis to achieve dosage compensation with males. But skewed X chromosome inactivation occurs in the female carriers, secondary to cell-autonomous selection against cells in which the abnormal X chromosome is active. Highly skewed X chromosome inactivation is likely to occur in POF which caused by subcytogenetic X chromosome deletion or translocation and X-linked gene mutation. The present study was performed to investigate whether highly skewed inactivation of X chromosome is observed in POF. METHODS: Eighty-six women with premature ovarian failure were studied and eighty-three normal women were enrolled as a control group. X chromosome inactivation pattern were determined by studying methylation pattern of androgen receptor gene. RESULTS: Seventy-six of the 86 POF patients were informative for X chromosome inactivation assay, 8 (10.5%) of them showed highly skewed X chromosome inactivation. In the age matched control group, 3 (4.1%) out of the 74 subjects showed highly skewed X chromosome inactivation. However, this finding is not statistically significant (p=0.2274). Among highly skewed X inactivation, one case of premature ovarian failure revealed 46,XX,del(X)(p21) by high resolution band karyotyping. Therefore highly skewed X inactivation can provide clues to evaluate the causes in POF. CONCLUSION: This study suggests that screening of skewed X chromosome inactivation for the POF will be useful to detect subcytogenetic X chromosome deletion or translocation and X-linked gene mutation associated with POF.

Comparison of the Early Postoperative Results after a Billroth I and a Billroth II Gastrectomy for Gastric Cancer

PURPOSE: The proper reconstructive technique after a partial gastrectomy for an adenocarcinoma of the stomach is often debated, but few data exist to clarify the issue. The aim of this study was to compare retrospectively the early postoperative results and complications after different anastomoses used during a partial gastrectomy for a gastric adenocarcinoma. MATENRIALS AND METHODS: We reviewed the hospital records of 218 patients who had undergone a subtotal gastrectomy for gastric cancer at Chosun University Hospital between January 1997 and July 2000. Of the 218 subtotal gastrectomies performed with curative intent, 127 reconstructions were Billroth I gastrectomies and 91 were Billroth II gastrectomies. The following data were analyzed: age, sex, tumor size, gastric resection margin, timing of removal of the nasogastric tube, first bowel movement, resumption of oral feeding, and postoperative complications. RESULTS: The timing of removal of the nasogastric tube was significantly earlier in the Billroth Igroup than in the Billroth II group (27.9+/-13.9 hours and 69.7+/-68 hours, respectively)(P<0.05). Resumption of oral feeding was possible on day 4.6+/-1.5 in the Billroth I group and on dsy 5.2+/-1.5 in the Billroth II group (P<0.05). There were no anastomotic leakage, postoperative bleeding, and postoperative mortality among the patients in either group. CONCLUSION: the Billroth Igastrectomy should be considered for patients undergoing a partial gastric resection for gastric cancer due to its physiological benefits and acceptable rate of complication.

The Necessity of Pyloroplasty after Esophagectomy and Esophagogastrostomy in the Gastric Replacement of the Esophagus

PURPOSE: In treating carcinoma of the esophagus, a gastric drainage procedure seems to be necessary with esophago gastrostomies because of the inevitable incidental bilateral truncal vagotomy which occurs during the esophagectomy. There are potential hazards with a pyloroplasty such as jeopardizing the blood supply to the mobilized stmach, shortening its length for substitution, leakage, dumping syndrome, and bile reflux gastritis. The aims of the study are to compare the postoperative outcome of patients with and without pyloroplasty after an esophagectomy for esophageal cancer, and to evaluate the necessity of pyloroplasty in the vagotomized intrathoracic stomach after esophageal surgery. METHODS: During the years 1996 to 2001, 23 patients with carcinoma of the esophagus underwent an esophagectomy followed by esophagogastrostomy with or without pyloroplasty. The medical records of the patients were evaluated retrospectively. RESULTS: There were no statiscally significant differences between the pyloroplasty group and the no-pyloroplasty group with regards to the average hospital stay, resumption of oral feeding, removal of the nasogastric tube, and the daily gastric drainage. CONCLUSION: Postoperative symptomatic evaluation of patients who had esophageal cancer and underwent an esoph-agectomy and an esophagogastrostomy, with or without pyloroplasty supports the concept that the drainage procedure is unnecessary in the gastric replacement of the esophagus.
