Abstract
Adenomyosis is linked to dysmenorrhea and infertility. The pathogenesis of adenomyosis remains unclear, and little is known of the genetic and epigenetic changes in the eutopic endometrium in adenomyosis, which may predispose patients to the invasion and migration of endometrial tissues into the myometrium. Transcriptome studies have identified genes related to various cell behaviors but no targets for therapeutic intervention. The epigenetics of the eutopic endometrium in adenomyosis have rarely been investigated. Endometrial tissue was obtained from premenopausal women with (n = 32) or without adenomyosis (n = 17) who underwent hysterectomy aged 34–57 years at a tertiary hospital. The methylome and transcriptome were assessed by using a Methylation 450 K BeadChip array and Affymetrix expression microarray. Protein expression was examined by immunohistochemistry. Differential methylation analysis revealed 53 lowly methylated genes and 176 highly methylated genes with consistent gene expression in adenomyosis, including three genes encoding potassium ion channels. High expression of KCNK9 in the eutopic and ectopic endometria in patients with adenomyosis but not in normal controls was observed. Hormone-free, antibody-based KCNK9 targeting is a potential therapeutic strategy for adenomyosis-related dysmenorrhea, menorrhagia, and infertility.

Abstract
When obstructive lesions from the uterus or ovaries are suspected, patients with hydronephrosis are usually referred to a gynecologist. Here, a case of suspected endometriosis-related hydroureteronephrosis is reported. A 43-year-old woman with hydronephrosis was found to have a left distal periureteral tumor on the computerized tomography scan. Before the operation, the hydroureteronephrosis was suspected caused by the obstruction of ureter, related with ureteral endometriosis; however, the postoperative pathology revealed the diagnosis of retroperitoneal well-differentiated liposarcoma. When female patients have hydronephrosis, gynecologic causes should be considered. Both benign and malignant causes are needed to include when making differential diagnosis. Therefore, robot-assisted surgery is a feasible option because of its lower morbidity rate and more precise dissection of soft tissue than laparotomy in both benign and malignant retroperitoneal tumors.

Abstract
Programmed death-ligand 1 (PD-L1), an immune checkpoint ligand, is recognized as a potential target for cancer immunotherapy as well as for the induction of transplantation tolerance. However, how the crosstalk between stem cell programming and cytokine signaling regulates PD-L1 expression during stem cell differentiation and cancer cell plasticity remains unclear. Herein, we reported that PD-L1 expression was regulated by SOX2 during embryonic stem cell (ESC) differentiation and lung cancer cell plasticity. PD-L1 was induced during ESC differentiation to fibroblasts and was downregulated during SOX2-mediated reprogramming of fibroblasts to induced pluripotent stem cells (iPSCs). Furthermore, SOX2 activation affected cancer cell plasticity and inhibited PD-L1 expression in lung cancer cells. We discovered that the H3K27ac signal at the PD-L1 locus was enhanced during ESC differentiation to fibroblasts as well as during cancer plasticity of SOX2-positive lung cancer cells to SOX2-negative counterparts. Romidepsin, an epigenetic modifier, induced PD-L1 expression in lung cancer cells, whereas TGF-β stimulation downregulated SOX2 but upregulated PD-L1 expression in lung cancer cells. Furthermore, in addition to PD-L1, the expressions of EGFR and its ligand HBEGF were downregulated by activation of endogenous SOX2 expression during lung cancer cell plasticity and iPSC reprogramming, and the activation of EGFR signaling by HBEGF upregulated PD-L1 expression in lung cancer cells. Together, our results reveal the crosstalk between SOX2 programming and cytokine stimulation influences PD-L1 expression, and these findings may provide insights into PD-L1-mediated therapeutics.

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
Twelve collaborating laboratories assayed 4 products, namely, Panax ginseng, Panax quinquefolius, and 2 ginseng products, for 6 ginsenosides: Rb1, Rb2, Rc, Rd, Re, andRg1. Collaborators also received a negative control for the recovery study. Pure ginsenosides were provided as reference standards for the liquid chromatography (LC) analysis and the system suitability tests. The LC analyses were performed on the methanol extract using UV detection at 203 nm. For P. ginseng, individual ginsenosides were consistent in their means; repeatability standard deviations (RSDr)rangedfrom4.17to5.09% and reproducibility standard deviations (RSDR) ranged from 7.27 to 11.3%. For P. quinquefolius, the Rb1 and Rb2 ginsenosides were higher and lower in concentration than P. ginseng, with RSDr values of 3.44 and 6.60% and RSDR values of 5.91 and 12.6% respectively, and other analytes at intermediate precisions. For ginseng commercial products, RSDr values ranged from 3.39 to 8.12%, andRSDR values ranged from 7.65 to 16.5%. A recovery study was also conducted for 3 ginsenosides: Rg1, Re, andRb1. The average recoveries were 99.9, 96.2, and 92.3%, respectively. The method is not applicable for the determination of Rg1 and Re in ginseng product at levels <300 mg/kg.

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
Uterine sarcoma is a very aggressive and highly lethal disease. Even after a comprehensive staging surgery or en block cytoreduction surgery followed by multimodality therapy (often chemotherapy and/or radiation therapy), many patients relapse or present with distant metastases, and finally die of diseases. The worst outcome of uterine sarcomas is partly because of their rarity, unknown etiology, and highly divergent genetic aberration. Uterine sarcomas are often classified into four distinct subtypes, including uterine leiomyosarcoma, low-grade uterine endometrial stromal sarcoma, high-grade uterine endometrial stromal sarcoma, and undifferentiated uterine sarcoma. Currently, evidence from tumor biology found that these tumors showed alternation and/or mutation of genomes and the intracellular signal pathway. In addition, some preclinical studies showed promising results for targeting receptor tyrosine kinase signaling, phosphatidylinositol 3-kinase/AKT/mammalian target of rapamycin pathway, various kinds of growth factor pathways, Wnt/beta-catenin signaling pathway, transforming growth factor β/bone morphogenetic protein signal pathway, aurora kinase A, MDM2 proto-oncogene, histone deacetylases, sex hormone receptors, certain types of oncoproteins, and/or loss of tumor suppressor genes. The current review is attempted to summarize the recurrent advance of targeted therapy for uterine sarcomas.

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
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
OBJECTIVE To evaluate the role of surgery, radiation therapy and chemotherapy in the management of small cell carcinoma of the uterine cervix (SCCC) through a retrospective study of Taiwanese Gynecologic Oncology Group. METHODS We reviewed the medical records and histological files of 144 patients with FIGO stages IA-IIB SCCC treated in 11 main hospitals in Taiwan from 1987 to 2009. RESULTS There were 110 patients receiving primary surgery and 34 primary radiation therapy. Most patients in each group also received chemotherapy as part of primary treatment. A lower loco-regional failure rate was observed in patients who received primary radiation therapy than in those who had primary surgery (6% vs. 27%; P=0.009). The 5-year overall survival (OS) was 89% for 13 surgically treated patients with cervical tumor ≤2cm and no lymphovascular space involvement (LVSI) in whom recurrence was noted in 2 of 4 patients without receiving adjuvant chemotherapy and none in the 9 patients who had chemotherapy. Excluding these 13 patients, primary radiation therapy with at least 5cycles of platinum-based chemotherapy (n=14, including 12 stages IB2-IIB) resulted in a 5-year OS of 78%, better than that of 46% by primary surgery (n=97, including 40 stages IB2-IIB) (P=0.046). CONCLUSIONS None of the 9 patients with cervical tumor ≤2cm and no LVSI showed disease recurrence after primary surgery and adjuvant chemotherapy. For most patients with stages I-II, primary radiation therapy with aggressive chemotherapy was associated with better survival than surgery.

Abstract
BACKGROUND The combination of bleomycin, etoposide and cisplatin (BEP) is currently the most widely used treatment for malignant ovarian germ cell tumours (MOGCTs). The aim of this study was to evaluate the efficacy and adverse effects of the 3-day BEP regimen in Taiwan. The prognostic factors of the MOGCT patients were also analysed. PATIENTS AND METHODS Two hundred and thirty-nine cases of MOGCTs were identified from the Taiwanese Gynecologic Oncology Group database, and 204 of those who received postoperative BEP chemotherapy were then analysed. RESULTS The estimated rate of no evidence of disease was 94.0% for 204 patients with adjuvant BEP regimen. Seven grade 3/4 haematological adverse effects including four subjects with neutropenia, one with pancytopenia and two with neutropenic fever were recorded in the 853 total courses of chemotherapeutic cycles. The rates of haematological and non-haematological adverse effects were 0.82% and 2.3%, respectively. No treatment-related mortality was noted. In the analysis of prognostic factors, only tumour stage had a significant impact on disease recurrence (95% confidence interval (CI), 4.2–94.4, p < 0.001) and disease-related mortality (95% CI, 2.2–163.9, p = 0.007). CONCLUSIONS The current 3-day adjuvant BEP regimen was effective and safe for patients with MOGCTs.

Abstract
MicroRNAs (miRNAs, miRs) are a cluster of naturally occurring small non-coding RNA molecules of 19-24 nucleotides in length. miRs control gene expression post-transcriptionally by binding to a specific site at the 3'-UTR of target mRNA, which results in mRNA cleavage and translation repression. Nearly 1000 miRs in the human genome have been identified, and it is believed that these miRs contribute to at least 60% of the human transcriptome. Recent research has shown that miRs are emerging as important regulators of cellular differentiation and dedifferentiation. In addition, dysregulation of miR expression may play a fundamental role in the onset, progression and dissemination of cancers. In this review, we focus on some paradigms of miR involvement in tumorigenesis, such as ovarian cancer, and also discuss the relationship between miRs and cancer stem cells.

Abstract
OBJECTIVE Our previous work revealed that host genes ZNF582, PTPRR, PAX1, and SOX1 are highly methylated in cervical intraepithelial neoplasias grade 3 or worse (CIN3(+)). In this study, we used a standardized testing assay to evaluate the clinical efficacy of these biomarkers in the triage of cytological diagnoses of low-grade squamous intraepithelial lesions (LSILs), and compared the performance with human papillomavirus (HPV) testing. METHODS This 2-year multicenter prospective study examined a population of 230 women from 12 medical centers who were diagnosed with LSILs on cervical cytology. Cervical scrapings were obtained prior to a colposcopy-directed biopsy for quantitative methylation analysis of ZNF582, PTPRR, PAX1, and SOX1, and HPV testing. Using logistic regression and receiver operating characteristic curve analyses, the abilities of methylated genes and HPV to predict CIN3(+) were assessed. RESULTS Fifteen (6.5%) of the 230 women with a cytological diagnosis of LSIL were confirmed to have CIN3(+) after a colposcopy-directed biopsy. Among the 4 methylated genes, ZNF582 was found to be the best biomarker for detecting CIN3(+). The sensitivities for methylated ZNF582 and HPV testing were 73% and 80%, and the specificities were 71% and 28%, respectively. The odds ratio for predicting CIN3(+) using methylated ZNF582 was 6.8 (95% confidence interval (CI) 2.1-22.1), which was much better than HPV testing (OR=1.6, 95% CI 0.4-5.8). CONCLUSION This is the first study to show that ZNF582 methylation analysis of cervical swabs may be a promising choice in the positive triage of cytological diagnoses of LSILs.

Abstract
We aimed to determine whether PAX1/SOX1 methylation could be translated to clinical practice for cervical neoplasia detection when used alone and in combination with current cytology-based Pap screening. We conducted a multicenter case-control study in 11 medical centers in Taiwan from December 2009 to November 2010. Six hundred seventy-six patients were included in the analysis, including 330 in the training set and 346 in the testing set. Multiplex quantitative methylation-specific polymerase chain reaction (PCR) was performed with a TaqMan probe system using a LightCycler 480 Real-Time PCR System (Roche). The level of human papilloma virus (HPV) was analyzed using a Hybrid Capture 2 system (Digene). Receiver operating characteristic curves were generated to obtain the best cutoff values from the training data set. The sensitivities, specificities, and accuracies were validated in the testing set. The sensitivities for methylated ((m)) PAX1(m) and SOX1(m) and HPV testing for detecting CIN3(+) lesions were 0.64, 0.71, and 0.89, and the specificities were 0.91, 0.77, and 0.68, respectively. Combined parallel testing of PAX1(m)/SOX1(m) tests with Pap smearing showed superior specificity (0.84/0.71 vs. 0.66, respectively) and similar sensitivity (0.93/0.96 vs. 0.97) to the combination of Pap smear results and HPV testing. Thus, combined parallel testing using Pap smears and PAX1 or SOX1 methylation tests may provide better performance than a combination of Pap smears with HPV testing in detection for cervical neoplasia.

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
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
Background. All published reports concerning secondary cytoreductive surgery for relapsed ovarian cancer have essentially been observational studies. However, the validity of observational studies is usually threatened from confounding by indication. We sought to address this issue by using comparative effectiveness methods to adjust for confounding. Methods. Using a prospectively collected administrative health care database in a single institution, we identified 1,124 patients diagnosed with recurrent epithelial, tubal, and peritoneal cancers between 1990 and 2009. Effectiveness of secondary cytoreductive surgery using the conventional Cox proportional hazard model, propensity score, and instrumental variable were compared. Sensitivity analyses for residual confounding were explored using an array approach. Results. Secondary cytoreductive surgery prolonged overall survival with a hazard ratio (95% confidence interval) of 0.76 (range 0.66-0.87), using the Cox proportional hazard model. Propensity score methods produced comparable results: 0.75 (range 0.64-0.86) by nearest matching, 0.73 (0.65-0.82) by quintile stratification, 0.71 (0.65-0.77) by weighting, and 0.72 (0.63-0.83) by covariate adjustment. The instrumental variable method also produced a comparable estimate: 0.75 (range 0.65-0.86). Sensitivity analyses revealed that the true treatment effects may approach the null hypothesis if the association between unmeasured confounders and disease outcome is high. Conclusions. This comparative effectiveness study provides supportive evidence for previous reports that secondary cytoreductive surgery may increase overall survival for patients with recurrent epithelial, tubal, and peritoneal cancers.

However, many pregnant women do not undergo culture-based screening, nor treatment with prophylactic antibiotics after a GBS risk-based approach. Therefore, the value of GBS detection in asymptomatic low-risk pregnant women is controversial. METHODS A cohort study of 354 asymptomatic pregnant women at more than 37 weeks' gestation who were planning to undergo vaginal delivery, and 118 neonates (107 paired samples of both mother and newborn), was conducted to evaluate the GBS colonization rate of these pregnant women and the subsequent vertical transmission rate, using a culture method. RESULTS The positive rate for GBS culture was 6.2% (22/354). Among 107 paired samples, six maternal samples and one neonatal sample were positive for GBS culture, with an estimated vertical transmission rate of 16.7% (1/6). CONCLUSION Although the positive rate of GBS culture was lower in asymptomatic low-risk pregnant women, the possibility of vertical transmission might be high. This finding is worthy of further investigation.

Abstract
Laparoscopic common bile duct exploration (LCBDE) is generally performed using a four- or five-port technique. We report a unique technique of two-port transcholedochal LCBDE with T-tube placement. Twelve consecutive patients with common bile duct (CBD) stones underwent LCBDE through two entry ports, one homemade single port (Uen port) inserted in a 2-cm umbilical wound and one 5-mm subxiphoid trocar port. With the assistance of a 1.2-mm needle that was inserted through a right lower intercostal space into the abdominal cavity to facilitate the operation, two-port dome-down laparoscopic cholecystectomy, choledochotomy, choledochoscopic removal of ductal caculi, and T-tube choldochostomy were performed with conventional methods using standard laparoscopic instruments along with manually operated angled shafts. After completion of the operation, the T-tube catheter was brought out through the subxiphoid trocar wound. All operations were completed successfully without the need of additional ports. There was no complication and no residual stones. Mean operation time was 120 minutes (range, 90 to 150 minutes), and mean postoperative hospital stay was 3.5 days (range, 3 to 4 days). Scarless wound healing was achieved except one T-tube scar. Two-port transumbilical LCBDE with T-tube choledochostomy is a feasible, safe, and effective technique that allows one-scar abdominal surgery for treatment of CBD stones. Further studies and the development of better instruments are necessary before this can be recommended as a standard procedure.

Abstract
Due to their immunomodulatory functions, mesenchymal stem cells (MSCs) have great potential for clinical applications to prevent rejection in organ transplantation and to prevent graft-versus-host disease in hematopoietic stem cell (HSC) transplantation. Since dendritic cells (DCs) play an important role in modulating diverse T cell responses, including rejection and graft-versus-host disease, the goal of this study was to investigate whether MSCs modulate DC differentiation from HSCs and if this effect could be one of the mechanisms for MSCs' immune-modulating functions. Our results demonstrate that differentiation of HSCs into mature DCs is inhibited in the presence of MSCs. Similar frequency of dendritic precursors in the cultures, either with or without MSCs, suggests that the inhibition of MSCs on the differentiation of mature DCs from HSCs could be due to the arresting of maturation at the dendritic precursor step. Reduced levels of cyclic AMP, adenosine 3',5'-cyclic monophosphate (cAMP) and beta-catenin in DC-like cells from the cocultures are detected, suggesting that induction of apoptosis and inhibition of differentiation could be the basis for the inhibition of mature DCs from HSCs by MSCs. Further, our results demonstrate that DCs derived from HSCs in the presence of MSCs are functionally impaired, especially for those after direct contact with MSCs. To investigate the basis of functional impairment, our data show downregulated tumor necrosis factor-alpha and transforming growth factor-beta1 secretion and upregulated interleukin-6 (IL6) and IL1beta secretion in the cultures with MSCs. Together, MSCs can inhibit differentiation of mature DCs from HSCs by arresting them at the precursor stage and induce their apoptosis. Further, HSC-derived DCs in the presence of MSCs are functionally impaired, which could be partly due to the upregulation of IL6 secretion.

Abstract
AIM To report the clinical experience of transumbilical single-port laparoscopic cholecystectomy (TUSPLC), using a homemade laparoscopic access port composed of two inexpensive and common pieces of equipment readily available in the operating room. METHODS Fifty consecutive patients with gallstones, including ten patients (20%) with acute cholecystitis, underwent single-port laparoscopic cholecystectomy (LC) using a homemade single port composed of a segment of corrugated breathing tube and a pair of surgical gloves. The port was inserted into the umbilicus for simultaneous placement of multiple conventional instruments into the abdominal cavity. All patients underwent dome-down LC using traditional instruments with manually angulated shafts; dissection was done using electrocautery or harmonic scalpel. RESULTS All but two procedures were completed uneventfully. Two patients with acute cholecystitis due to dense adhesions in the triangle of Calot necessitated conversion to two- and four-port laparoscopic procedures, respectively. Operative time averaged 73 ± 2 min for chronic cholecystitis and 95 ± 5 min for acute cholecystitis. There were no perioperative port-related or surgical complications, except for two patients who developed wound seroma and recovered after conservative treatment. We found that healing of the umbilical wound left virtually no scar in all patients. CONCLUSION The homemade umbilical port reported in this study is useful for multiple instrument access and allows TUSPLC to be performed safely, with its inherent cosmetic and cost advantages. Further studies of this technique are ongoing.

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
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
The concept of regulatory T cells was first described in the early 1970s, and regulatory T cells were called suppressive T cells at that time. Studies that followed have demonstrated that these suppressive T cells negatively regulated tumor immunity and contributed to tumor growth in mice. Despite the importance of these studies, there was extensive skepticism about the existence of these cells, and the concept of suppressive T cells left the center stage of immunologic research for decades. Interleukin-2 receptor alpha-chain, CD25, was first demonstrated in 1995 to serve as a phenotypic marker for CD4+ regulatory cells. Henceforth, research of regulatory T cells boomed. Regulatory T cells are involved in the pathogenesis of cancer, autoimmune disease, transplantation immunology, and immune tolerance in pregnancy. Recent evidence has demonstrated that regulatory T cell-mediated immunosuppression is one of the crucial tumor immune evasion mechanisms and the main obstacle of successful cancer immunotherapy. The mechanism and the potential clinical application of regulatory T cells in cancer immunotherapy are discussed.

Abstract
BACKGROUND Two alternative surgical techniques for elective laparoscopic cholecystectomy (LC), low-pressure insufflation of the peritoneal cavity and abdominal wall lifting (AWL), have been developed over time to minimize the disadvantages associated with CO2-elicited pneumoperitoneum. To the best of our knowledge, the 2 methods have seldom been compared as regards their relative advantages and disadvantages. METHODS Eighty patients scheduled for elective LC were randomized into either a low-pressure (8 mmHg) CO2 insufflation method (LPLC) group, or a gasless technique using a subcutaneous abdominal wall lifting device (GLC group). The duration of the surgical procedure, the surgical results including level of postoperative pain, and perioperative cardiopulmonary function changes experienced by the members of both groups were compared. RESULTS Laparoscopic surgery was completed for all but 1 patient from each group due to an inadequate surgical-site exposure. There was no mortality for study participants, and no major complications were noted for members of either group. The LPLC group evidenced a shorter surgical duration as compared to the GLC group (77 +/- 28 minutes vs. 98 +/- 27 minutes, respectively; p < 0.01) and a lower incidence of postoperative shoulder pain (2/38 vs. 8/39, respectively; p < 0.05), although significant differences in intraoperative pulmonary function were noted (an increased PaCO2, Pet CO2 and peak-airway pressure and decreased arterial blood pH; p < 0.01) for the LPLC group compared to the GLC group. CONCLUSION Both alternative methods for this type of surgery appeared feasible and safe for LC. Low-pressure CO2 pneumoperitoneum had a shorter surgical duration and less postoperative shoulder pain compared to the GLC technique, but did not feature any other advantage over the AWL technique with regard to impact on cardiopulmonary function.

Abstract
The PROLENE Hernia System (PHS) is a bilayer patch device providing an anterior approach to preperitoneal inguinal hernia repair. To provide improved expansion of the underlay patch of PHS, a modified device featuring a deploying “pocket” in the double-layered underlay graft was designed. The deploying “pocket” is flat in shape and harbors a perimeter that can act as a receiving unit for surgical force, which is exerted outward and backward to expand the underlying graft. Through a unique surgical technique using an angled metal pusher to facilitate access to intrapocket manipulation, the underlay graft not only can be fully deployed, but can be securely placed in the preperitoneal space to cover the entire myopectineal orifice. This allows effective treatment of inguinal/femoral herniation. Based on the encouraging clinical results obtained using a procedure that incorporates this strategy at our hospital, it can be concluded that this modified device/technique for PHS is one of the best inguinal/femoral hernia repair methods available.

Abstract
Leiomyoma of the fallopian tube is extremely rare. Most cases are asymptomatic and found incidentally at autopsy or unrelated operation. These leiomyomas tend to be singular, small, and unilateral, with a resultant rare preoperative diagnosis. They are often managed with laparotomy, as seen in the literature review. Therefore, preoperative imaging is never reported. We describe a case of leiomyoma of the fallopian tube, which was suspected before operation and treated by laparoscopic approach. Transvaginal ultrasound clearly showed a hypoechoic solid mass separate from the left ovary and uterus in a 44-year-old woman. Color Doppler ultrasound detected low impedance flow in this mass. Diagnostic laparoscopy and the follow-up laparoscopic salpingoectomy revealed a primary leiomyoma of the fallopian tube. We conclude that powerful ultrasound could be helpful in diagnosing rare gynecologic disorders but laparoscopy can be used for definite diagnosis and management of such disorders.
