Abstract
Background Ovarian cancer is the leading cause of cancer-related death among women. Complete cytoreductive surgery followed by platinum-taxene chemotherapy has been the gold standard for a long time. Various compounds have been assessed in an attempt to combine them with conventional chemotherapy to improve survival rates or even overcome chemoresistance. Many studies have shown that an antidiabetic drug, metformin, has cytotoxic activity in different cancer models. However, the synergism of metformin as a neoadjuvant formula plus chemotherapy in clinical trials and basic studies remains unclear for ovarian cancer. Methods We applied two clinical databases to survey metformin use and ovarian cancer survival rate. The Cancer Genome Atlas dataset, an L1000 microarray with Gene Set Enrichment Analysis (GSEA) analysis, Western blot analysis and an animal model were used to study the activity of the AKT/mTOR pathway in response to the synergistic effects of neoadjuvant metformin combined with chemotherapy. Results We found that ovarian cancer patients treated with metformin had significantly longer overall survival than patients treated without metformin. The protein profile induced by low- concentration metformin in ovarian cancer predominantly involved the AKT/mTOR pathway. In combination with chemotherapy, the neoadjuvant metformin protocol showed beneficial synergistic effects in vitro and in vivo. Conclusions This study shows that neoadjuvant metformin at clinically relevant dosages is efficacious in treating ovarian cancer, and the results can be used to guide clinical trials.

Abstract
PURPOSE Multiple chromosomal aneuploidies may be associated with maternal malignancies and can cause failure of noninvasive prenatal screening (NIPS) tests. However, multiple chromosomal aneuploidies show poor specificity and selectivity for diagnosing maternal malignancies. METHODS This multicenter retrospective analysis evaluated 639 pregnant women who tested positive for multiple chromosomal aneuploidies on initial NIPS test between January 2016 and December 2017. Women were assessed using genome profiling of copy-number variations, which was translated to cancer risk using a novel bioinformatics algorithm called the cancer detection pipeline (CDP). Sensitivity, specificity, and positive predictive value (PPV) of diagnosing maternal malignancies were compared for multiple chromosomal aneuploidies, the CDP model, and the combination of CDP and plasma tumor markers. RESULTS Of the 639 subjects, 41 maternal malignant cancer cases were diagnosed. Multiple chromosomal aneuploidies predicted maternal malignancies with a PPV of 7.6%. Application of the CDP algorithm to women with multiple chromosomal aneuploidies allowed 34 of the 41 (83%) cancer cases to be identified, while excluding 422 of 501 (84.2%) of the false positive cases. Combining the CDP with plasma tumor marker testing gave PPV of 75.0%. CONCLUSION The CDP algorithm can diagnose occult maternal malignancies with a reasonable PPV in multiple chromosomal aneuploidies-positive pregnant women in NIPS tests. This performance can be further improved by incorporating findings for plasma tumor markers.

Abstract
OBJECTIVE The coexistence of maternal malignancy and pregnancy has received increasing attention in Noninvasive prenatal testing (NIPT) studies. Malignancy in pregnant women potentially affects the copy number variation (CNV) profile in NIPT results. Only one case of hematologic cancer has been reported in a Hong-Kong pregnant women, and solid tumors have never been reported in pregnant Chinese women. CASE REPORT The patients with dysgerminoma and cervical cancer showed aberrant chromosomal aneuploidies in NIPT and concordant patterns of genome disruption in tumor tissues. The genomic aberrations in the gastric cancer patient had similar copy number variation pattern of gastric cancer. CONCLUSION The findings in this study and the literature review further validate the effect of maternal malignancy on the copy number variation profile in NIPT data and strengthen the possibility of detecting malignant tumors with NIPT in the future.

Abstract
Endometrial carcinoma is a cancer derived from oncogenesis of the regenerating uterine cavity, in which cytokine stimulation shapes cell differentiation and tissue remodeling. Expression of the stem cell factors SOX2, OCT4, NANOG, and MYC has been linked to tumor malignancy in several cancers. However, how these stem cell factors crosstalk with cytokine signaling to promote malignancy in endometrial carcinoma is still elusive. Here we report that the expression of SOX2 and MYC, but not that of OCT4 and NANOG, correlate with poor histological differentiation and prognosis, while SOX2 expression is negatively associated with MYC level. We found that SOX2-high endometrial carcinoma cells possessed a higher colony-forming ability than their SOX2-low counterparts, and knockdown of SOX2 attenuated the colony-forming ability. We observed that SOX2 regulated EGFR expression in a SOX2–EGFR positive feedback loop. EGF stimulation induced SOX2 expression and promoted migration of endometrial carcinoma cells, whereas TGF-β stimulation inhibited SOX2 expression and attenuated the colony-forming ability. Immunohistochemistry analysis revealed that SOX2 expression correlated with lymph node infiltration of endometrial carcinoma. Our findings support that cytokine-induced stem cell factor SOX2 possesses oncogenic properties, with the potential to serve as a prognostic biomarker in endometrial carcinoma.

Abstract
OBJECTIVE Our previous study has shown that high expression of α2,3-sialytransferase type I was associated with advanced stage serous type epithelial ovarian cancer (EOC). The aim of the current study further attempts to evaluate the altered α 2,3-sialylation on the behavior of clear cell type EOC (C-EOC). MATERIALS AND METHODS Immunohistochemistry staining, bioinformatics analysis and tissue array were used to disclose the clinical significance of over α2,3-sialylation in C-EOC. An α2,3 sialylation inhibitor, soyasaponin I (SsaI) was used to investigate the behavior change of the C-EOC cell line. RESULTS We reconfirmed that α2,3-sialylation, instead of α2,6- sialylation, was associated with late-stage C-EOC. Soyasaponin I could inhibit α2,3-sialylation of C-EOC cell lines and increase E-cadherin expression with subsequently suppressing migration of C-EOC cells. CONCLUSIONS The current study demonstrated the important role of α2,3-linked sialylation in C-EOC and targeting of α2,3-linked sialylation might offer as a potential therapeutic strategy in the future.

Abstract
Epithelial ovarian cancer (EOC) has the highest mortality rate among gynecologic cancers due to advanced stage presentation, peritoneal dissemination, and refractory ascites at diagnosis. We investigated the role of α2,3-sialyltransferase type I (ST3GalI) by analyzing human ovarian cancer datasets and human EOC tissue arrays. We found that high expression of ST3GalI was associated with advanced stage EOC. Transwell migration and cell invasion assays showed that high ST3GalI expression enhanced migration of EOC cells. We also observed that there was a linear relation between ST3GalI expression and epidermal growth factor receptor (EGFR) signaling in EOC patients, and that high ST3GalI expression blocked the effect of EGFR inhibitors. Co-Immunoprecipitation experiments demonstrated that ST3GalI and EGFR were present in the same protein complex. Inhibition of ST3GalI using a competitive inhibitor, Soyasaponin I (SsaI), inhibited tumor cell migration and dissemination in the in vivo mouse model with transplanted MOSEC cells. Further, SsaI synergistically enhanced the anti-tumor effects of EGFR inhibitor on EOC cells. Our study demonstrates that ST3GalI regulates ovarian cancer cell migration and peritoneal dissemination via EGFR signaling. This suggests α2,3-linked sialylation inhibitors in combination with EGFR inhibitors could be effective agents for the treatment of EOC.

Abstract
An important role of genetic factors in the development of breast cancer (BC) or ovarian cancer (OC) in Taiwanese (ethnic Chinese) patients has been suggested. However, other than germline BRCA1 or BRCA2 mutations, which are related to hereditary breast-ovarian cancer (HBOC), cancer-predisposition genes have not been well studied in this population. The aim of the present study was to more accurately summarize the prevalence of genetic mutations in HBOC patients using various gene panels ranging in size from BRCA1/2 alone to multi-gene panels. Among 272 HBOC patients analyzed, the prevalence of BRCA1, BRCA2 and non-BRCA1/2 pathogenic mutations was 7.7% (21/272), 6.8% (16/236) and 8.2% (13/159), respectively. The total mutation rate was 18.4% (50/272). Although no founder mutations were identified in this study, two recurrent mutations, BRCA1 (c.3607C>T) and BRCA2 (c.5164_5165 delAG), were found. The main pathogenic/likely pathogenic mutations in non-BRCA1/2 genes included ATM, BRIP1, FANCI, MSH2, MUYTH, RAD50, RAD51C and TP53. The prevalence rate of gene mutations in HBOC patients did not differ with respect to whether BC or OC was the first diagnosis or they presented a family history of the disease or their age at diagnosis. HBOC patients with both BC and OC exhibited a higher prevalence rate of mutations (50.0%) than patients with OC (25.0%) or BC (8.6%) alone. In conclusion, evaluation of hereditary cancer risk in Taiwan HBOC patients, particularly individuals with double cancer, is strongly encouraged. Panel testing can yield additional genomic information, and widespread and well-designed panel testing will help in assessing more accurate mutational prevalence of risk genes.

Abstract
The interplay between tumor microenvironment and cancer that causes chemoresistance remains unclear. By analyzing public available microarray datasets, we identified that periostin (POSTN) was overexpressed in cancer stroma in epithelial ovarian cancer (EOC) patients. Immunohistochemistry analysis showed overexpression of stromal POSTN is a powerful independent poor prognostic predictor for EOC patients. Furthermore, patients with high levels of stromal POSTN tend to have higher percentage of cisplatin resistance compared to those with low levels of stromal POSTN. Moreover, we found POSTN treatment can induce cisplatin resistant and activate AKT pathway in A2780 cells in vitro. Inhibition of AKT activity by AKT inhibitor MK-2206 abolished POSTN-induced AKT activation and cisplatin resistance in vitro. Taken together, we found high POSTN expression in cancer microenvironment is correlated with poor prognosis in EOC patients and associated with platinum resistance. The effect of POSTN in cancer stroma cells may activate AKT pathway in tumor and AKT inhibitor can be beneficial to augment the efficacy of existing cancer therapeutics.

Abstract
Abstract
Compared to other subtypes of tumors, triple negative breast cancers (TN BCa) currently suffer from limited knowledge on its etiology and treatment options. Transmitochondrial cybrids (cybrid) and multiple OMICs approaches were used to understand mitochondrial reprogramming and mitochondria-regulated cancer pathways in TN BCa. Analysis of cybrids and established BCa cell lines showed that metastatic TN BCa maintain high levels of ATP through fatty acid β-oxidation and activate Src oncoprotein by its autophosphorylation. Inhibition and induction of β-oxidation including the shRNA mediated knockdown strategies, and analysis of patient derived xenograft (PDX) models confirmed the role of mitochondrial β-oxidation in Src activation and metastasis. Analysis of BCa clinical data further reaffirmed the role of mitochondrial β-oxidation in Src regulation and their significance in BCa metastasis. This study is innovative in showing the mitochondrial reprogramming mediated regulation of a major cancer pathway by its post-translation modification.

Abstract
Transmitochondrial cybrids and multiple OMICs approaches were used to understand mitochondrial reprogramming and mitochondria-regulated cancer pathways in triple-negative breast cancer (TNBC). Analysis of cybrids and established breast cancer (BC) cell lines showed that metastatic TNBC maintains high levels of ATP through fatty acid β oxidation (FAO) and activates Src oncoprotein through autophosphorylation at Y419. Manipulation of FAO including the knocking down of carnitine palmitoyltransferase-1A (CPT1) and 2 (CPT2), the rate-limiting proteins of FAO, and analysis of patient-derived xenograft models confirmed the role of mitochondrial FAO in Src activation and metastasis. Analysis of TCGA and other independent BC clinical data further reaffirmed the role of mitochondrial FAO and CPT genes in Src regulation and their significance in BC metastasis.

Abstract
Abstract
Endometrial cancer is the most common gynecologic malignancy in United States. The prognosis is generally better because most patients are diagnosed at early stage. However, the overall survival rate declines to 10∼20% at advanced stage. There are no effective treatment in the management of patient with late stage of endometrial cancer or distant metastasis. EpCAM (also called TACSTD1 or CD326), a transmembrane glycoprotein, can mediate cell-cell adhesion. Its overexpression negatively correlates with clinical survival in gallbladder cancer, ampullary carcinoma, and squamous cell carcinoma of head &. neck. However, a controversial role of EpCAM is reported in Lynch syndrome and rectal cancer as a tumor suppressor gene. To study the role of EpCAM in endometrial cancer, we manipulate the EpCAM expression in loss-of-function experiment in vitro; the results demonstrate that decrease of EpCAM expression is significantly related to increase invasion ability and diminish cell proliferation. These finding can be reversed after gain-of-function in EpCAM knock-down endometrial cancer cells. EpCAM knock-down is indeed linked to the cell signaling pathway of proliferation (regulation of cell proliferation GO:0042127, regulation of cell death:GO:0010941, regulation of apoptosis: GO:0042981) and migration (biological adhesion:GO:0022610, cell adhesion:GO:0007155, cell migration:GO:0016477) from microarray analysis. Significant more number of lymph node metastasis can be found in vivo at mice with IUI (intra-uterine injection) of EpCAM knock-down cells; moreover, smaller tumor size is observed in subcutaneously injected mice. Among the patients with endometrial cancer, the clinicopathologic characteristics, such as stage, lymph node metastasis, CA-125 value, and overall survival, are significantly related to the low EpCAM expression. Conclusively, diminishing EpCAM can promote endometrial cancer invasion; furthermore, the EpCAM expression is an significant prognostic factor in human endometrial cancer. These data has important implication that development targeting EpCAM in the treatment of endometrial cancer is the new application in future.

Abstract
Abstract
Introduction
Epithelial ovarian cancer is the third most common gynecologic cancer in the United States but a leading cause of gynecologic cancer deaths. Previous finding that numbers of circulating tumor cells (CTCs) in the blood of ovarian cancer patients are prognostically significant. Moreover, comprehensive analyses of ovarian cancer genomes may provide more information for precise cancer treatments. Genomic analysis of circulating tumor cells (CTC) can provide possible approach for EOC patients who lack primary tumor tissue or present with un-resectable metastatic diseases. The discordance between whole genome amplification of circulating tumors and primary tumor should be validated firstly and so we conducted a pilot analysis of CTC capture and targeted NGS in EOC cell lines.
Methods and materials
Under IRB approval, EOC cell lines, different numbers of SKOV-3 (serous adenocarcinoma) and ES-2 (clear cell carcinoma) were spiked in fresh blood samples (20 ml) of healthy donor and captured by CytoQuestTM CR system or negative enrichment method (Abnova, Taipei, Taiwan). CTCs were identified by pan-CK, CD45 and DAPI expression and stained with CEP8 FISH for aneuploidy. Spiked CTCs of two cell lines were captured and underwent whole genome amplification by PicoPLEX™ WGA kit (Rubicon Genomic, MI, USA). The WGA DNA product and DNA of two primary cell lines were prepared libraries for TruSight(TM) Tumor sequencing panel (Illumina Inc.MI,USA) according to manufacturer's instruction. Sequencing procedure were performed on MiSEQ system(Illumina Inc.) by a local service provider.
Results
SKOV-3 and ES-2 can be stained and captured with these antibodies. Mean recovery of these cells were more than 80% by both systems. However, ES-2 is less Pan-CK stained but still could be captured by this system. WGA products of each one, three and five ES-2 cells and one SKOV3 cell were prepared well for library. We choose one cell WGA product and DNA extracted from primary SKOV-3 and ES2 were subjected to targeted 26 genes mutational analysis composed in TruSight Tumor panel. Average coverage depth for each amplicon is minimum 1000x with 7000x means. We would like to show if any discordance appear due to the acquisition of DNA WGA in the single cells, of which the analysis is currently ongoing.
DISCUSSION
Our study would like to demonstrate the condition of variants calls of single tumor cells isolated from whole blood samples and primary tumor in a targeted mutation analysis using NGS after a highly automated isolation workflow. This approach provides a pilot workflow for studying the heterogeneity within the CTC population in blood samples of patients with tumor and their primary tumor and the results can also document the possibility of WGA-induced bias of a recently commercialized WGA kit.

Abstract
BACKGROUND Ovarian cancer (OCa) peritoneal metastasis is the leading cause of cancer-related deaths in women with limited therapeutic options available for treating it and poor prognosis, as the underlying mechanism is not fully understood. METHOD The clinicopathological correlation of G9a expression was assessed in tumor specimens of ovarian cancer patients. Knockdown or overexpression of G9a in ovarian cancer cell lines was analysed with regard to its effect on adhesion, migration, invasion and anoikis-resistance. In vivo biological functions of G9a were tested by i.p. xenograft ovarian cancer models. Microarray and quantitative RT-PCR were used to analyze G9a-regulated downstream target genes. RESULTS We found that the expression of histone methyltransferase G9a was highly correlated with late stage, high grade, and serous-type OCa. Higher G9a expression predicted a shorter survival in ovarian cancer patients. Furthermore, G9a expression was higher in metastatic lesions compared with their corresponding ovarian primary tumors. Knockdown of G9a expression suppressed prometastatic cellular activities including adhesion, migration, invasion and anoikis-resistance of ovarian cancer cell lines, while G9a over-expression promoted these cellular properties. G9a depletion significantly attenuated the development of ascites and tumor nodules in a peritoneal dissemination model. Importantly, microarray and quantitative RT-PCR analysis revealed that G9a regulates a cohort of tumor suppressor genes including CDH1, DUSP5, SPRY4, and PPP1R15A in ovarian cancer. Expression of these genes was also inversely correlated with G9a expression in OCa specimens. CONCLUSION We propose that G9a contributes to multiple steps of ovarian cancer metastasis and represents a novel target to combat this deadly disease.

Abstract
BACKGROUND Epithelial ovarian cancer is basically a heterogeneous disease with different chemosensitivity and distinct molecular alternations for each histological subtype. In order to assess whether the results of clinical trials can be extrapolated to a new country, it is critical to first examine whether the relative frequencies is homogenous across countries. METHODS Cancer registry database from a single institution in Taiwan combined with systematic review of the global literature on the relative frequencies of histological subtypes between 2003 and 2012 was provided. RESULTS Of 175 titles identified, 41 studies met inclusion/exclusion criteria. Globally, for each subtype, the median value of relative frequencies for serous subtype was 45.0%, with the Philippines (16.0%), Indonesia (22.7%), and Brazil (30.1%) as the three lowest countries and South Africa (68.0%), Greece (71.5%), and India (86.7%) as the three highest countries; for mucinous subtype, 11.4%, Italy (3.0%), Australia (3.4%), and Japan (5.4%) were the three lowest countries, while Indonesia (29.1%), Singapore (30.3%), and South Korea (38.6%) were the three highest countries; for endometrioid subtype, 12.6%, India (1.6%), Greece (5.7%), and Portugal (7.6%) were the three lowest countries, while Taiwan (24.8%), Egypt (25.0%), and Austria (25.5%) were the three highest countries; and for clear cell subtype, 5.3%, Pakistan (1.0%), Iran (2.0%), and Brazil (2.1%) were the three lowest countries while Thailand (16.0%), Taiwan (16.8%), and Spain (18.8%) were the three highest countries. CONCLUSIONS Relative frequencies of subtypes were not homogenous across countries. This diversity may reflect the geographical and ethnic variations. Globally, epithelial ovarian cancer is a heterogeneous disease with a heterogeneous distribution pattern.

Abstract
OBJECTIVE To compare the prognosis of patients with advanced-stage primary peritoneal serous papillary carcinoma (PSPC) or papillary serous ovarian cancer (PSOC). MATERIALS AND METHODS This was a retrospective case-control study and included two study groups: one with stage III/IV PSPC (n = 38) patients and the other with PSOC (n = 53) patients. Patients were matched for histologic subtype (serous tumor), tumor stage, tumor grade, residual disease at the end of debulking surgery (primary or interval), and age (±5 years). RESULTS Mean age was significantly greater for patients with PSPC (63.03 ± 11.88 years) than for patients with PSOC (55.92 ± 12.56 years, p = 0.008). Optimal debulking surgery was performed initially in 71.9% of PSPC patients and 66.0% of PSOC patients. In addition, 93.9% of PSPC patients and 92.3% of PSOC patients were treated with platinum-paclitaxel chemotherapy. The frequency of high-grade tumors was significantly higher in the PSPC (100%) than in the PSOC group (68.3%; p < 0.001). Progression-free survival (PFS) was similar in the PSPC [median 12 months, 95% confidence interval (CI) 7.3-16.7] and PSOC groups (median 16.7 months, 95% CI 12.9-20.4; p = 0.470). Overall survival was shorter in the PSPC (median 62 months, 95% CI 19.6-104.4) than in the PSOC group (median 77.5 months, 95% CI 69.7-85.2; p = 0.006, log-rank statistic). CONCLUSION PFS was similar for advanced-stage PSPC and PSOC patients. Since the PSPC patients tended to be older and have more high-grade tumors, OS was shorter for PSPC than for POSC patients. Thus, management of the two types of cancer should not differ.

Abstract
BACKGROUND Advanced maternal age (AMA) is the most frequent indication for amniocentesis in predicting balanced reciprocal translocations, and abnormal ultrasound findings are indications in predicting unbalanced reciprocal translocations; however, to date, no studies have focused on Robertsonian translocations. METHODS A retrospective review was conducted on 16,749 pregnant women who underwent midtrimester amniocentesis between January 1981 and December 2010. Robertsonian translocations were identified in 39 cases. RESULTS The percentage of Robertsonian translocations in all amniocentesis cases was 0.23% (39/16,749); 31 were balanced and eight were unbalanced. De novo abnormality occurred in 17 cases, or in 43.6% of all Robertsonian translocations. The two major indications for amniocentesis with a diagnosis of Robertsonian translocations were AMA (41.0%, n = 16) and a parent with abnormal karyotypes (18.0%, n = 7). The highest percentage of Robertsonian translocations was found in parents with abnormal karyotypes (2.8%, 7/252), but neither of the indications were clearly superior for detecting de novo Robertsonian translocations. CONCLUSION Although AMA is an indication for amniocentesis in approximately two-fifths of cases with Robertsonian translocations, the indication of parent with abnormal karyotypes was more likely to lead to the detection of non-de novo Robertsonian translocations, suggesting that parents with abnormal karyotypes need careful prenatal consultation.

Abstract
BACKGROUND Reciprocal translocation is the most common type of translocation; however, there are only a few studies that address the indications for reciprocal translocation in amniocentesis. Here we share our data, based on 30 years' experience in a single tertiary center, to investigate the rates and indications for amniocentesis in cases of reciprocal translocations. METHODS A retrospective review of 16,749 pregnant women, who underwent midtrimester amniocentesis between January 1981 and December 2010, was conducted. Seventy-four cases of reciprocal translocation were identified. RESULTS The percentage of reciprocal translocations in all amniocentesis cases was 0.44% (74/16,749); of these 74 cases, 56 were balanced and 18 unbalanced. De novo abnormality occurred in 23 cases, which constituted 31.1% of all reciprocal translocations. The three major indications for amniocentesis with a diagnosis of reciprocal translocation included advanced maternal age (AMA, 52.7%), a parent with an abnormal karyotype (17.6%), and abnormal biochemical markers in the maternal serum (12.2%). For individual types of reciprocal translocations (balanced and unbalanced), except for the presence of abnormal biochemical markers in maternal serum, both AMA and a parent with an abnormal karyotype were primary indications for amniocentesis. However, the highest percentage of reciprocal translocations in all amniocentesis cases was found in cases involving a parent with an abnormal karyotype (5.16%, 13/252). CONCLUSION Patients with a parent who carries an abnormal karyotype should be encouraged to undergo amniocentesis in prenatal consultation, since the risk of a diagnosis of reciprocal translocation can be particularly high.

Abstract
Endodermal sinus tumor, also known as yolk sac tumor (YST), is a malignant germ cell tumor that most frequently occurs in the testis, the ovary, and sacrococcygeal areas in children. YSTs are highly aggressive and because of the early metastatic or invasive pattern, their prognosis has been poor. Treatment methods for YSTs are usually intensive, including multiagent chemotherapy, and have shown to improve patient survival significantly; therefore, it is important to consider the reproductive function of these patients with long-term survival. Herein, we present the case of a 31-year-old female, who was diagnosed with unilateral ovarian YST at the age of 13. The patient was treated with fertility-sparing surgery and postoperative adjuvant chemotherapy. During the subsequent long-term follow-up, she was not only free of disease, but also had a successful, naturally conceived pregnancy at 31 years of age. We, therefore, conclude that YST is a curable disease, and that fertility-preservation surgery and subsequent immediate combination chemotherapy is the treatment of choice.

Abstract
OBJECTIVE To present a prenatal diagnosis of microdeletion 16p13.11 with partial monosomy of 2q37.1-qter and partial trisomy of 7p15.3-pter in a fetus with bilateral ventriculomegaly, agenesis of corpus callosum, and polydactyly. CASE REPORT A 41-year-old well-being Taiwanese, nulligravida woman received amniocentesis at a gestational age of 18 weeks for advanced maternal age. The fetus' karyotype showed 46,XY,der(2)t(2;7)(q36.2;p15.1). Both parents also received cytogenetic examinations and the mother's karyotype revealed 46,XX,t(2;7)(2q36.2;p15.1). High-resolution ultrasound showed the fetus had bilateral ventriculomegaly, agenesis of corpus callosum, and polydactyly of the right hand. After the termination of this pregnancy, the whole genome oligonucleotide-base array comparative genomic hybridization (CGH) by using fetal skin cells demonstrated a 8.44-Mb deletion at 2q37.1 (234602276-243041305), a 22.8-Mb duplication (65558-22869338) at 7p15.3, and an additional 1.32-Mb deletion (14968855-16292235) at 16p13.11. CONCLUSION Array CGH is a useful tool not only to discover the genomic imbalance at the breakpoints as well as to detect unexpectedly complex rearrangements in other chromosomes. Our case also provided evidence that genomic aberration at chromosome 16p13.11 involves in the formation of polydactyly.

Abstract
OBJECTIVE We sought to compare myomectomy performed by laparotomy (LT), and 2 other modified approaches: ultraminilaparotomy (UMLT) and laparoscopically assisted UMLT for uterine fibroids with a size <8 cm and the number <5. STUDY DESIGN A cohort study, including 79 (35.3%) women in the LT group, 71 (31.7%) in the UMLT group, and 74 (33.0%) in the laparoscopically assisted UMLT group, was conducted. The outcome was measured by comparing surgical parameters, immediate postoperative recovery, and therapeutic outcomes. RESULTS The median follow-up was 52 months with similar recurrence rates in the 3 groups. The modified approaches had advantages not only in the surgical parameters, but also in postoperative recovery, compared to LT (all P < .05). CONCLUSION UMLT and laparoscopically assisted UMLT can be used successfully in place of LT in the management of uterine fibroids.

Abstract
Small supernumerary marker chromosomes (sSMC) originating from chromosome 10 are rare. Only seven cases have been documented, and among those three cases were diagnosed prenatally. We reported on another prenatal diagnosis of a de novo mosaic sSMC in an apparently normal female fetus whose mother had conceived with assisted reproductive technology (ART) procedures. G-banding analysis of amniotic cells was performed. Spectral karyotyping (SKY) and fluorescence in situ hybridization (FISH) studies with chromosome 10-specific alphoid satellite DNA probe were used to identify the chromosome 10 origin of the sSMC. Further FISH study with telomeric sequence probes showed that the sSMC lacked a hybridization signal, suggesting that the marker could be a ring chromosome. FISH studies using BAC clone probes specific for the regions within 10p11.2, 10q11.1, and 10q11.2 showed that the short arm breakpoint was located between 29.8 and 30.7 Mb from the 10p telomere, and that the long arm breakpoint was located less than 43.6 Mb from the 10p telomere. The karyotype of the fetus was 47,XX,+mar. ish der(10)(SKY+ CEP 10+, CTD-2130I7+, RP11-89J23-)/46,XX. Oligonucleotide microarray-based copy number variations (CNV) analysis was also performed and showed a 6.7 Mb duplication from 10p11.2 to 10q11.2 (36.2-42.9 Mb) with Affymetrix SNP-array 6.0 genotype: arr cgh. 10p11.2q11.2(CN_519687 --> CN_541524) X 3. At the 1-year follow-up, the baby did not have any findings of the trisomy 10p syndrome. This observation provided further credence to the concept that additional chromosome material of proximal 10p11.2 may not contribute to the trisomy 10p syndrome phenotype.

Abstract
We report a case of chronic hepatitis B carrier gravida who had acute exacerbation during pregnancy. She had been taking lamivudine 100 mg/qd for 17 months when hepatitis B virus (HBV) DNA in the YMDD region of the polymerase gene (YMDD motif) mutant was noted. After discontinuing lamivudine, she became pregnant. HBeAg became positive again and liver enzymes were elevated during the first trimester of pregnancy. She received the hepatoprotective agent silymarin 150 mg bid at 13+2 gestational weeks. Serum aspartate aminotransferase (AST) dropped to 757 U/L at 15+0 gestational weeks, but serum alanine aminotransferase (ALT) flared up to 2,230 U/L and AST to 2,250 U/L at 17+1 gestational weeks. Serum HBV-DNA test revealed serum HBV-DNA concentration of 7.31 x 10(8) copies/mL. Lamivudine 100 mg/qd and silymarin 150 mg/bid were initiated at 17+1 gestational weeks. Liver function showed gradual decline to ALT 341 U/L and AST 91 U/L at 21+0 gestational weeks, while HBeAg(+) converted to (-) and anti-HBe(-) converted to (+). Further treatment with lamivudine 100 mg/qd continued for 3 months. Serum HBV-DNA concentrations decreased to 3.19 x 10(2) copies/mL at 36+6 gestational weeks. Spontaneous delivery of a male baby weighing 3314 g occurred at 38+3 gestational weeks. The neonatal physical check-up revealed no congenital anomalies, and fetal growth was within normal reference ranges, suggesting that lamivudine may be safely used in the treatment of chronic hepatitis B with acute exacerbation during the second trimester of pregnancy.

Abstract
PURPOSE OF INVESTIGATION To assess the clinical use of F-18-fluorodeoxyglucose positron emission tomography (FDG-PET) in the post-therapy surveillance of uterine sarcoma. METHODS Eight whole-body FDG-PET studies were performed in seven women with previously treated uterine sarcoma. Conventional image studies (computed tomography) and physical examinations were performed for follow-up. All FDG-PET studies were indicated to localize suspected recurrences noted by conventional methods. RESULTS The per case sensitivity of the FDG-PET studies and CT scans was 85.7% (6/7) and 100% (7/7), respectively (p = 0.174). FDG-PET was able to detect seven extrapelvic metastastic sites below the diaphragm (7/7, sensitivity: 100%), including the liver, spleen, paraaortic lymph node, spine and paracolic gutter, as well as pulmonary lesions in five patients, while the CT scan detected only three lesions (3/7, sensitivity: 42.9%; p = 0.070). FDG-PET detected only four recurrent pelvic lesions (4/6) and CT scan detected six (6/6) recurrent pelvic lesions (66.7% vs 100%, p = 0.455). CONCLUSIONS The FDG-PET showed a better detection rate than the abdominal CT scan for extrapelvic metastatic lesions and a similar detection rate as well as abdominal CT scan. FDG-PET can serve as a useful detection tool for patients with uterine sarcomas because nearly 80% of recurrence involve an extrapelvic site.

Abstract
OBJECTIVE Complications during laparoscopic surgery involving the bladder, bowel, and major vessels have been reported extensively. However, uterine manipulator-associated injuries are seldom reported. CASE REPORT We describe herein the case of a 28-year-old female patient who underwent a laparoscopic cystectomy 5 days after cervical conization, during which the uterine manipulator perforated the anterior cul-de-sac through the cervix. Fortunately, the wound healed with conservative treatment and no adverse consequences were found. CONCLUSION This case serves to highlight the potential for complications following seemingly benign maneuvers.
