Abstract
This paper presents a new approach for denoising Partial Discharge (PD) signals using a hybrid algorithm combining the adaptive decomposition technique with Entropy measures and Group-Sparse Total Variation (GSTV). Initially, the Empirical Mode Decomposition (EMD) technique is applied to decompose a noisy sensor data into the Intrinsic Mode Functions (IMFs), Mutual Information (MI) analysis between IMFs is carried out to set the mode length K. Then, the Variational Mode Decomposition (VMD) technique decomposes a noisy sensor data into K number of Band Limited IMFs (BLIMFs). The BLIMFs are separated as noise, noise-dominant, and signal-dominant BLIMFs by calculating the MI between BLIMFs. Eventually, the noise BLIMFs are discarded from further processing, noise-dominant BLIMFs are denoised using GSTV, and the signal BLIMFs are added to reconstruct the output signal. The regularization parameter λ for GSTV is automatically selected based on the values of Dispersion Entropy of the noise-dominant BLIMFs. The effectiveness of the proposed denoising method is evaluated in terms of performance metrics such as Signal-to-Noise Ratio, Root Mean Square Error, and Correlation Coefficient, which are are compared to EMD variants, and the results demonstrated that the proposed approach is able to effectively denoise the synthetic Blocks, Bumps, Doppler, Heavy Sine, PD pulses and real PD signals.

Abstract
Cancer cells actively promote aerobic glycolysis to sustain their metabolic requirements through mechanisms not always clear. Here, we demonstrate that the gatekeeper of mitochondrial Ca2+ uptake, Mitochondrial Calcium Uptake 1 (MICU1/CBARA1) drives aerobic glycolysis in ovarian cancer. We show that MICU1 is overexpressed in a panel of ovarian cancer cell lines and that MICU1 overexpression correlates with poor overall survival (OS). Silencing MICU1 in vitro increases oxygen consumption, decreases lactate production, inhibits clonal growth, migration and invasion of ovarian cancer cells, whereas silencing in vivo inhibits tumour growth, increases cisplatin efficacy and OS. Mechanistically, silencing MICU1 activates pyruvate dehydrogenase (PDH) by stimulating the PDPhosphatase-phosphoPDH-PDH axis. Forced-expression of MICU1 in normal cells phenocopies the metabolic aberrations of malignant cells. Consistent with the in vitro and in vivo findings we observe a significant correlation between MICU1 and pPDH (inactive form of PDH) expression with poor prognosis. Thus, MICU1 could serve as an important therapeutic target to normalize metabolic aberrations responsible for poor prognosis in ovarian cancer.

Abstract
Abstract
BACKGROUND: Black women diagnosed with endometrial carcinoma have a higher risk of recurrence compared with white women. Higher recurrence risk among black women is due, in part, to a greater frequency of aggressive tumor characteristics including non-endometrioid histologies and advanced stage tumors. The risk of recurrence for black and white women within distinct tumor groupings has not been well-examined due to low numbers of black women and under-representation of aggressive histologic subtypes in single institution studies. Therefore, we examined the association between self-reported race and recurrence risk stratified by histologic subtype in the NRG Oncology/Gynecology Oncology Group (GOG) 210, a prospective observational study that enrolled 6,124 newly diagnosed endometrial carcinoma patients between 2003 and 2011.
METHODS: We restricted this analysis to 618 black and 4,316 white women with endometrial carcinoma. At study enrollment, women completed a questionnaire that assessed risk factors for gynecologic cancers. Recurrence, defined as evidence of disease following complete response to primary therapy, was abstracted from medical records. Tumor characteristics were available from surgical pathology reports and a centralized review by pathologists with expertise in gynecologic cancers. Cox proportional hazards regression models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for the association between race (black vs. white) and recurrence risk in models stratified by histologic subtype (low-grade endometrioid, high-grade endometrioid, serous, mixed epithelial, carcinosarcoma, clear cell) and adjusted for stage (I, II, III, IV), age at diagnosis (continuous), and adjuvant therapy (none, chemotherapy, radiation, chemotherapy and radiation, unknown). We also examined income ($20,000-$39,999, $40,000-$69,999, ≥$70,000) and education (high school/GED, some college/technical school, college graduate/beyond) as potential mediators of the association between race and endometrial carcinoma recurrence risk using the Baron-Kenny method. Median follow-up time was 5 years.
RESULTS: Black women were more frequently diagnosed with non-endometrioid (52.9% vs. 31.8%) and advanced stage (Stage III or IV: 29.0% vs. 21.1%) tumors compared with white women. Recurrence was documented in 26% of black and 17% of white endometrial carcinoma patients. In histologic subtype-stratified models adjusted for stage, age, and adjuvant therapy, a higher risk of recurrence was noted in black women with low-grade endometrioid (HR=1.65, 95% CI=1.07-2.54), mixed epithelial (HR=1.75, 95% CI=1.13-2.71), or carcinosarcomas (HR=1.55, 95% CI=1.03-2.31) compared with white women. No significant race-recurrence relationships were observed among women diagnosed with high-grade endometrioid, serous, or clear cell tumors. After adjustment for income and education, the association of black race and recurrence risk remained elevated, but was not statistically significant: low-grade endometrioid (HR=1.52, 95% CI=0.97-2.38), mixed epithelial (HR=1.56, 95% CI=0.98-2.50), and carcinosarcoma (HR=1.48, 95% CI=0.98-2.25). Further, neither income nor education were significantly associated with recurrence risk in the multivariable models.
CONCLUSIONS: Our study provides evidence that racial disparities in endometrial carcinoma recurrence risk vary by histologic subtype. Socioeconomic factors do not explain black-white differences in endometrial carcinoma recurrence risk. Future studies exploring the role of biological factors and post-diagnosis surveillance contributing to racial differences in endometrial carcinoma recurrence are warranted.

Abstract
BACKGROUND In current clinical trials of treating ovarian cancer patients, how to accurately predict patients' response to the chemotherapy at an early stage remains an important and unsolved challenge. PURPOSE To investigate feasibility of applying a new quantitative image analysis method for predicting early response of ovarian cancer patients to chemotherapy in clinical trials. MATERIAL AND METHODS A dataset of 30 patients was retrospectively selected in this study, among which 12 were responders with 6-month progression-free survival (PFS) and 18 were non-responders. A computer-aided detection scheme was developed to segment tumors depicted on two sets of CT images acquired pre-treatment and 4-6 weeks post treatment. The scheme computed changes of three image features related to the tumor volume, density, and density variance. We analyzed performance of using each image feature and applying a decision tree to predict patients' 6-month PFS. The prediction accuracy of using quantitative image features was also compared with the clinical record based on the Response Evaluation Criteria in Solid Tumors (RECIST) guideline. RESULTS The areas under receiver operating characteristic curve (AUC) were 0.773 ± 0.086, 0.680 ± 0.109, and 0.668 ± 0.101, when using each of three features, respectively. AUC value increased to 0.831 ± 0.078 when combining these features together. The decision-tree classifier achieved a higher predicting accuracy (76.7%) than using RECIST guideline (60.0%). CONCLUSION This study demonstrated the potential of using a quantitative image feature analysis method to improve accuracy of predicting early response of ovarian cancer patients to the chemotherapy in clinical trials.

Abstract
The present study aims to quantitatively measure adiposity-related image features and to test the feasibility of applying multivariate statistical data analysis-based prediction models to generate a novel clinical marker and predict the benefit of epithelial ovarian cancer (EOC) patients with and without maintenance bevacizumab-based chemotherapy. A dataset involving computed tomography (CT) images acquired from 59 patients diagnosed with advanced EOC was retrospectively collected. Among them, 32 patients received maintenance bevacizumab following primary chemotherapy, while 27 did not. A computer-aided detection scheme was developed to automatically segment visceral and subcutaneous fat areas depicted on CT images of abdominal sections, and 7 adiposity-related image features were computed. Upon combining these features with the measured body mass index, multivariate data analyses were performed using three statistical models (multiple linear, logistic and Cox proportional hazards regressions) to analyze the association between the model-generated prediction results and the treatment outcome, including progression-free survival (PFS) and overall survival (OS) of the patients. The results demonstrated that applying all three prediction models yielded a significant association between the adiposity-related image features and patients' PFS or OS in the group of the patients who received maintenance bevacizumab (P<0.010), while there was no significant difference when these prediction models were applied to predict both PFS and OS in the group of patients that did not receive maintenance bevacizumab. Therefore, the present study demonstrated that the use of a quantitative adiposity-related image feature-based statistical model may generate a novel clinical marker to predict who will benefit among EOC patients receiving maintenance bevacizumab-based chemotherapy.

Abstract
OBJECTIVE High-grade serous carcinoma (HGSC) generally presents at an advanced stage with poor long-term (LT) survival. Here we describe clinical features found in women surviving HGSC for ten or more years. METHODS A multi-center research consortium was established between five participating academic centers. Patient selection criteria included high-grade serous ovarian, fallopian tube, or peritoneal carcinoma with at least ten years of follow up. Non-serous, borderline tumors and low-grade serous subtypes were excluded. RESULTS The 203 identified LT ten-year survivors with HGSC were diagnosed at a median age of 57years (range 37-84years). The majority of patients had stage IIIC (72.4%) disease at presentation. Of those who underwent primary cytoreductive surgery, optimal cytoreduction was achieved in 143 (85.6%) patients. After a median follow up of 144months, 88 (46.8%) patients did not develop recurrent disease after initial treatment. Unexpected findings from this survey of LT survivors includes 14% of patients having had suboptimal cytoreduction, 11% of patients having an initial platinum free interval of <12months, and nearly 53% of patients having recurrent disease, yet still surviving more than ten years after diagnosis. CONCLUSIONS LT survivors of HGSC of the ovary generally have favorable clinical features including optimal surgical cytoreduction and primary platinum sensitive disease. The majority of patients will develop recurrent disease, however many remained disease free for more than 10years. Future work will compare the clinical features of this unusual cohort of LT survivors with the characteristics of HGSC patients having less favorable outcomes.

Abstract
BACKGROUND Papillary renal-cell carcinoma, which accounts for 15 to 20% of renal-cell carcinomas, is a heterogeneous disease that consists of various types of renal cancer, including tumors with indolent, multifocal presentation and solitary tumors with an aggressive, highly lethal phenotype. Little is known about the genetic basis of sporadic papillary renal-cell carcinoma, and no effective forms of therapy for advanced disease exist. METHODS We performed comprehensive molecular characterization of 161 primary papillary renal-cell carcinomas, using whole-exome sequencing, copy-number analysis, messenger RNA and microRNA sequencing, DNA-methylation analysis, and proteomic analysis. RESULTS Type 1 and type 2 papillary renal-cell carcinomas were shown to be different types of renal cancer characterized by specific genetic alterations, with type 2 further classified into three individual subgroups on the basis of molecular differences associated with patient survival. Type 1 tumors were associated with MET alterations, whereas type 2 tumors were characterized by CDKN2A silencing, SETD2 mutations, TFE3 fusions, and increased expression of the NRF2-antioxidant response element (ARE) pathway. A CpG island methylator phenotype (CIMP) was observed in a distinct subgroup of type 2 papillary renal-cell carcinomas that was characterized by poor survival and mutation of the gene encoding fumarate hydratase (FH). CONCLUSIONS Type 1 and type 2 papillary renal-cell carcinomas were shown to be clinically and biologically distinct. Alterations in the MET pathway were associated with type 1, and activation of the NRF2-ARE pathway was associated with type 2; CDKN2A loss and CIMP in type 2 conveyed a poor prognosis. Furthermore, type 2 papillary renal-cell carcinoma consisted of at least three subtypes based on molecular and phenotypic features. (Funded by the National Institutes of Health.).

Abstract
Recently we reported that gold nanoparticles (AuNPs) inhibit ovarian tumor growth and metastasis in mice by reversing epithelial-mesenchymal transition (EMT). Since EMT is known to confer drug resistance to cancer cells, we wanted to investigate whether anti-EMT property of AuNP could be utilized to sensitize ovarian cancer cells to cisplatin. Herein, we report that AuNPs prevent cisplatin-induced acquired chemoresistance and stemness in ovarian cancer cells and sensitize them to cisplatin. AuNPs inhibit cisplatin induced EMT, decrease the side population cells and key stem cell markers such as ALDH1, CD44, CD133, Sox2, MDR1 and ABCG2 in ovarian cancer cells. Mechanistically, AuNPs prevent cisplatin-induced activation of Akt and NF-κB signaling axis in ovarian cancer cells that are critical for EMT, stem cell maintenance and drug resistance. In vivo, AuNPs sensitize orthotopically implanted ovarian tumor to a low dose of cisplatin and significantly inhibit tumor growth via facilitated delivery of both AuNP and cisplatin. These findings suggest that by depleting stem cell pools and inhibiting key molecular pathways gold nanoparticles sensitize ovarian cancer cells to cisplatin and may be used in combination to inhibit tumor growth and metastasis in ovarian cancer.

Abstract
Abstract
Background: Adult granulosa cell tumors account for ∼70% of sex cord stromal tumors of the ovary. Most behave as low-grade malignancies and present as stage I disease. However 20% recur, often after a prolonged time (median time to recurrence 6 years). Current therapeutic options (bleomycin/etoposide/cisplatin (BEP), hormone therapy, bevacizumab) have shown modest efficacy in the setting of advanced or recurrent disease. Prior genomic studies of aGCT identified recurrent FOXL2 mutations as characteristic of this tumor type, however this mutation is not currently amenable to targeted therapy. We present the CGP of 70 advanced/recurrent stage aGCT with identification of CRGAs and include a description of a patient response to CGP-matched targeted therapy.
Methods: DNA was extracted from 70 FFPE aGCT clinical specimens. Hybridization captured libraries of 236 (FoundationOne, n = 28) or 315 (FoundationOne, n = 42) genes, plus select introns frequently rearranged in cancer, which were sequenced to high (median 780x), uniform coverage. All classes of genomic alterations (base subs, small in/dels, rearrangements, and copy number alterations) were evaluated and reported. CRGA were defined as GA associated with on-label targeted therapies and targeted therapies in mechanism-driven clinical trials.
Results: 70 samples, 10% from primary site tissue and 90% from metastatic sites were included. The patients were women aged 30-80 (median 56.5y) with predominantly advanced stage aGCT. 68 cases (97%) had the FOXL2 402C>G mutation and 61% of cases had at least one additional GA (total n = 165) including 37 different genes (avg 2.4 GA per tumor) of which 27 were CRGA (avg 0.44 per tumor). 40% of aGCT cases featured ≥ 1 CRGA, including 14 (20%) cases with CRGA in the PI3K/Akt/mTOR pathway. The most common CRGAs observed were: MLL2 (10%),PIK3CA (8.6%), CDKN2A/B (8.6%), AKT1 (4.3%), KRAS (4.3%); and NRAS (2.8%). To date, we are aware of one patient with an AKT1 missense mutation in the pleckstrin homology domain (AKT1 Q79K) who showed a durable 6-month partial response to AKT-directed targeted treatment.
Conclusions: Almost two-thirds of advanced stage aGCT demonstrate GAs in addition to the pathognomonic FOXL2 mutation. 40% of cases demonstrate other targetable mutations, most commonly in the PI3K/Akt/mTOR pathway which present the opportunity for targeted therapy. This first account of a clinical response to CGP-directed targeted therapy in aGCT demonstrates potential efficacy of an AKT inhibitor in a subset of patients suffering from this otherwise treatment refractory tumor. Patients who have exhausted other SOC therapy for metastatic aGCT may similarly achieve clinical benefit from CGP-directed therapeutic decision-
making and this provides support for development of further mutation-matched therapeutic trial designs.

Abstract
Exosomes are 30-100 nm bodies secreted from almost all types of cells into the extracellular spaces. They enclose in their lumen active genetic information in the form of messenger RNA (mRNA), micro RNA (miRNA), DNA and active peptides that are representative of the parental cell and can be isolated from different body fluids. Exosomes can participate in inter-cellular communication by trafficking molecules to their target cells. Because they can stably carry cargo including miRNA, mRNA, and proteins and can pass through stringent biological barriers (e.g., blood brain barrier) without eliciting an immune response, they are considered as an ideal acellular vehicle for drug delivery. In this review, we describe the structure and biogenesis of exosomes and new directions related to their role in diagnosis and treatment of diseases, especially for cancer. We also discuss potential challenges associated with exosomes that should be addressed before exosome-based therapy can be applied to clinical settings.

Abstract
Elevated lipid metabolism is implicated in poor survival in ovarian cancer (OC) and other cancers; however, current lipogenesis-targeting strategies lack cancer cell specificity. Here, we identify a novel role of cystathionine beta-synthase (CBS), a sulphur amino acid metabolizing enzyme highly expressed in several ovarian cancer cell lines, in driving deregulated lipid metabolism in OC. We examined the role of CBS in regulation of triglycerides, cholesterol and lipogenic enzymes via the lipogenic transcription factors SREBP1 and SREBP2. CBS silencing attenuated the expression of number of key enzymes involved in lipid synthesis (FASN and ACC1). Additionally CBS abrogates lipid uptake in OC cells. Gene silencing of CBS or SREBPs abrogated cellular migration and invasion in OC, while ectopic expression of SREBPs can rescue phenotypic effects of CBS silencing by restoring cell migration and invasion. Mechanistically, CBS represses SREBP1 and SREBP2 at the transcription levels by modulating the transcription factor Sp1. We further established the roles of both CBS and SREBPs in regulating ovarian tumor growth in vivo. In orthotopic tumor models, CBS or SREBP silencing resulted in reduced tumor cells proliferation, blood vessels formation and lipid content. Hence, cancer-selective disruption of the lipid metabolism pathway is possible by targeting CBS and, at least for OC, promises a profound benefit.

Abstract
OBJECTIVE The purpose of this multicenter, open label, randomized phase III study was to determine whether ixabepilone resulted in improved overall survival (OS) compared with commonly used single-agent chemotherapy (doxorubicin or paclitaxel) in women with locally advanced, recurrent, or metastatic endometrial cancer with at least one failed prior platinum-based chemotherapeutic regimen. METHODS Patients were randomized 1:1 to ixabepilone (40mg/m(2)), or either paclitaxel (175mg/m(2)) or doxorubicin (60mg/m(2)), every 21days. Patients that had previously received an anthracycline were randomized to ixabepilone or paclitaxel; all other patients were randomized to ixabepilone or doxorubicin. An interim analysis of futility for OS was planned. RESULTS At the time of database lock, 496 patients were randomized to receive ixabepilone (n=248) or control (n=248); nine patients in the control arm were not treated. The interim analysis of futility for OS (219 events) favored the control chemotherapy arm (hazard ratio=1.3 [95% confidence interval: 1.0-1.7], stratified log rank test P=0.0397), indicating that the study would not meet its primary objective. The study was discontinued based on the interim OS results. The frequency of adverse events was comparable between the treatment arms. CONCLUSIONS The study did not meet its primary objective of improving OS in the ixabepilone arm compared to the control chemotherapy arm. A favorable risk/benefit ratio was not observed for ixabepilone versus control at the time of the interim analysis. The safety results were consistent with the known safety profiles of ixabepilone and control.

Abstract
OBJECTIVE Patients with endometrial carcinoma who progress after first-line chemotherapy have a poor prognosis. Phosphoinositide 3-kinase (PI3K) inhibitors are investigational treatment options in this setting. This study evaluated the efficacy and safety of the PI3K inhibitor pilaralisib (SAR245408; XL147) in advanced or recurrent endometrial carcinoma. METHODS This Phase II, multicenter, single-arm, open-label study enrolled patients with histologically confirmed advanced or recurrent endometrial carcinoma, who had received one or two prior chemotherapy regimens. Patients received pilaralisib 600mg capsules or 400mg tablets once daily. Primary endpoints were objective response rate (ORR), proportion of patients with progression-free survival (PFS) >6months and safety. Molecular profiling in archival tumor tissue and circulating tumor DNA were performed to identify molecular markers associated with response or resistance to pilaralisib. RESULTS 67 patients were enrolled, of which 50 and 17 patients had received one or two prior regimens, respectively. Complete or partial tumor responses occurred in two patients each (ORR 6.0%); three had tumors with normal PTEN expression and PIK3R1 mutations and one had a tumor with PTEN protein deficiency. However, there was no association between molecular alterations and clinical activity. Rate of PFS>6months was 11.9%. The most commonly reported treatment-related adverse events (AEs) were rash (40.3%), diarrhea (37.3%) and fatigue (28.4%). The most commonly reported treatment-related grade ≥3 AEs were rash (9.0%), diarrhea (4.5%) and increased alanine aminotransferase (4.5%). CONCLUSIONS Pilaralisib was associated with a favorable safety profile and minimal antitumor activity in advanced or recurrent endometrial carcinoma.

Abstract
This open-label, two-arm, phase II clinical trial evaluated the antitumor activity and safety profile of PM00104 (Zalypsis(®)) administered as a 1-h, weekly, intravenous infusion (days 1, 8 and 15; every 4 weeks) at a dose of 2 mg/m(2) to patients with advanced and/or metastatic endometrial (EC) or cervical cancer (CC) after one previous line of systemic chemotherapy. Twelve patients (median age, 61.5 years) with pretreated EC received a median of 2 treatment cycles (range 1-5) and seven patients (median age, 38 years) with pretreated CC received 2 treatment cycles. None achieved objective tumor response. Median progression-free survival (PFS) was 1.8 months, and median overall survival (OS) was 5.5 months in EC (median follow-up = 20.1 months); median PFS was 1.5 months, and median OS was 5.6 months in CC (median follow-up = 17.1 months). The most common toxicities reported were mild to moderate asthenia, nausea, vomiting and diarrhea. Despite PM00104 showing mostly mild, predictable, manageable and reversible toxicity, protocol criteria for further recruitment were not met in EC, a futility analysis was done and recruitment was stopped; a low patient recruitment rate together with no evidence of activity in CC resulted in early study closure.

Abstract
Background ME-143, a second-generation tumor-specific NADH oxidase inhibitor, is broadly active against human cancers in vitro and in vivo. This first-in-human dose-escalation study evaluated the dose-limiting toxicities (DLTs), pharmacokinetics, safety, tolerability, and preliminary anti-tumor activity of ME-143 in patients with advanced solid tumors. Methods Patients with advanced solid tumors were treated in a 3 + 3 escalation design. ME-143 was administered via intravenous infusion on days 1, 8, and 15 of the first 28-day cycle, and weekly thereafter; the final cohort received twice-weekly treatment. Samples for pharmacokinetic analysis were collected during cycle 1. Treatment continued until disease progression or unacceptable toxicity. Results Eighteen patients were treated: 2.5 mg/kg (n = 3); 5 mg/kg (n = 3); 10 mg/kg (n = 3); 20 mg/kg (n = 6); 20 mg/kg twice-weekly (n = 3). There were no DLTs observed. Nearly all treatment-related toxicities were grade 1/2, specifically (all grades) nausea (22 %) and fatigue (17 %). Two patients experienced infusion reactions at the 20 mg/kg dose level, one of which was grade 4. Stable disease was documented in three patients with colorectal cancer, cholangiocarcinoma, and anal cancer. Pharmacokinetic exposures were linear and dose-dependent, with a half-life of approximately 5 h. Conclusions ME-143 was well-tolerated when administered intravenously at the maximally administered/recommended phase 2 dose of 20 mg/kg once weekly to patients with advanced solid tumors. Though limited clinical activity was observed with monotherapy, inhibitors of tumor-specific NADH oxidase such as ME-143 may derive their greatest benefit in combination with cytotoxic chemotherapy.

Abstract
BACKGROUND Sagopilone is the first fully synthetic epothilone in clinical development and has demonstrated promising preclinical activity. This phase I/II, prospective, open-label trial investigated the efficacy and safety of sagopilone plus carboplatin in patients with recurrent platinum-sensitive ovarian cancer (OC). METHODS In phase I (dose-escalation stage), patients with OC recurring at least 6 months after platinum-containing chemotherapy received 3-h infusions of sagopilone (initial dose of 12 mg m(-2)) followed by carboplatin every 3 weeks, for 2-6 treatment courses. Patients enrolled in phase II received 3-h infusions of 16 mg m(-2) sagopilone. Efficacy was assessed using modified Response Evaluation Criteria in Solid Tumors (modRECIST) and Gynecologic Cancer InterGroup CA125 criteria. The safety and tolerability of sagopilone were also evaluated. RESULTS In all, 45 patients received sagopilone at 12 mg m(-2) or 16 mg m(-2). There were 29 confirmed tumour responses (21 modRECIST and 8 CA125) across both treatment groups, indicating that the primary objective of the study was reached. The main adverse events (AEs) reported were peripheral neuropathy (75.6%), fatigue (71.1%) and nausea (64.4%). Grade ≥3 AEs occurred in 35 patients (77.8%). No deaths related to the study drug were reported. CONCLUSION Sagopilone in combination with carboplatin was effective and toxicities were manageable in patients with recurrent platinum-sensitive OC.

Abstract
OBJECTIVE The safety and efficacy of gemcitabine plus carboplatin (GC) or paclitaxel plus carboplatin (TC) induction regimens with or without paclitaxel consolidation therapy were assessed in ovarian cancer (OC). METHODS Patients with stage IC-IV OC were randomized to either GC (gemcitabine 1,000 mg/m(2), days 1 and 8, plus carboplatin area under the curve [AUC] 5, day 1) or TC (paclitaxel 175 mg/m(2) plus carboplatin AUC 6, day 1) every 21 days for up to six cycles. Patients with complete response (CR) were allowed optional consolidation with paclitaxel 135 mg/m(2) every 28 days for ≤ 12 months. Patients without CR received single-agent crossover therapy at induction doses/schedules until CR, disease progression (PD), or unacceptable toxicity. PD or death in 636 patients was required to compare induction arms with 80% statistical power for progression-free survival (PFS), the primary endpoint. RESULTS Randomized induction therapy was received by 820 of 919 patients enrolled; 352 patients with CR received paclitaxel consolidation whereas 155 patients without CR received single-agent crossover therapy. PFS was similar for GC and TC (median, 20.0 and 22.2 months, respectively; P=.199). Despite high censoring rates (>52%), overall survival was longer for TC (median, 57.3 versus 43.8 months for GC; P=.013). Controlling for patient characteristics including performance status, residual tumor size, and tumor stage, there was no statistical difference in a multivariate analysis (HR=1.22; 95% CI=0.99-1.52; P=.067). CONCLUSIONS GC does not improve PFS over TC as first-line induction chemotherapy in OC. Although favoring TC, overall survival analyses were limited by the study design and high censoring rates.

Abstract
OBJECTIVE To compare the tolerability, efficacy, and safety profiles of pegylated liposomal doxorubicin in combination with carboplatin (PLD-Carbo) with those of gemcitabine-carboplatin (Gem-Carbo) for the treatment of patients with platinum-sensitive recurrent ovarian cancer (PSROC) by reviewing the published literature. METHODS Using the PubMed database, a systematic review of peer-reviewed literature published between January 2000 and September 2009 was undertaken to identify studies related to the treatment of patients with PSROC with PLD-Carbo or Gem-Carbo. Studies reporting either response rate, progression-free survival (PFS), and/or overall survival (OS) were included. Treatment regimens, efficacy endpoints, and safety profiles were compared between the two combination therapies. RESULTS Ten studies evaluating 608 patients (PLD-Carbo: 5 studies, 278 patients; Gem-Carbo: 5 studies, 330 patients) were identified. The mean planned doses were: PLD, 34.8 mg/m(2) and Gem, 993 mg/m(2). The dose intensity reported in Gem trials was lower (75% of the planned dose) than the dose intensity reported in PLD trials (93.7% of the planned dose), suggesting better tolerability for the PLD-Carbo regimen. Among patients receiving PLD-Carbo, 60.2% achieved a response (complete, 27.0%; partial, 33.2%), versus 51.4% of patients treated with Gem-Carbo (complete, 19.2%; partial, 32.2%). The median PFS times were 10.6 months and 8.9 months in the PLD-Carbo and the Gem-Carbo populations, respectively. The median OS was longer for the PLD-Carbo regimen (27.1 months) than for the Gem-Carbo regimen (19.7 months). The hematological safety profiles were comparable in the two groups, although grade III or IV anemia (PLD-Carbo, 13.6%; Gem-Carbo, 24.5%) and neutropenia (PLD-Carbo, 45.5%; Gem-Carbo, 62.9%) were more common in patients receiving Gem-Carbo. CONCLUSION Results from this systematic analysis of peer-reviewed literature suggest that PLD-Carbo therapy is a rational alternative to Gem-Carbo for the treatment of patients with PSROC.

Abstract
The diagnosis of endometrial hyperplasia and endometrial type adenocarcinoma arising within the uterine cavity has long been rested on morphologic criteria. Although distinction between normal endometrial epithelium from adenocarcinoma is usually straightforward, the separation between normal and hyperplastic endometrium, particularly those cases without atypia, can be a diagnostic challenge. The same is true in separation of hyperplastic endometrium with atypia from endometrial-type endometrial adenocarcinoma. Type 2 3alpha-/type 5 17beta-hydroxysteroid dehydrogenase (HSD) (AKR1C3) is a multifunctional enzyme involved in androgen, estrogen, progesterone, and pros-taglandin metabolism. Its expression has been shown in the epithelium of the renal tubules, urothelial epithelium, and endothelial cells in normal tissues as well as in prostatic adenocarcinoma. The proliferation and maintenance of endometrial epithelium is dependent on both estrogen and progesterone; and AKR1C3-mediated steroid metabolism may play a critical role in the maintenance of viable normal and abnormal endometrial epithelium. We studied the expression of AKR1C3 in 33 endometrial biopsy specimens including 13 cases of normal proliferative endometrium, 8 cases of hyperplastic endometrium with and without atypia, and 12 cases of primary endometrial adenocarcinoma of endometrial type. We demonstrated a uniform, diffuse, and strong expression of AKR1C3 in normal endometrial epithelium but not in endometrial stromal cells. In contrast, the expression of AKR1C3 is reduced in both hyperplastic and carcinomatous endometrial epithelium. These findings suggest that AKR1C3 may play important roles in the physiology of endometrial cells and that suppressed AKR1C3 expression may represent a feature that allows differentiation of hyperplastic and neoplastic endometrial epithelium from normal endometrial epithelium. However, reduced AKR1C3 expression cannot distinguish hyperplastic endometrium from endometrial adenocarcinoma of endometrial type. The biologic and pathological roles of AKR1C3 in endometrial epithelium require further investigation.

Abstract
e16501 Background: An array-based comparative genomic hybridization (aCGH) analysis was performed to determine if frequent (>40%) copy number aberrations (CNAs) exist in African American (AA) versus Caucasian (C) women with stage I versus stage IIIC/IV endometrioid endometrial cancers (EEC). Methods: Tumor DNA was isolated from 80 frozen primary tumors from the GOG-210 protocol. RPCI 19K BAC arrays were hybridized (GeneTAC HybStation) and scanned (Gene Pix 4200AL Laser Scanner). Spot fluorescence values were quantified using ImaGene, vetted for quality and loess corrected with adjustments for chip-specific spatial effects. The genome was segmented to identify regions with common copy number means (DNAcopy software). Posterior aberration probabilities for the regions were obtained using CGHcall and data was visualized and annotated using iGenomicViewer in R. Validation will be performed by fluorescence in situ hybridization using select BAC probes and endometrial cancer tissue microarrays (TMAs) with either 400 cases linked with clinical, treatment and outcome data or 180 AA versus 120 C women from GOG-136. Results: Recurrent CNAs were identified in all stage and race groups. Distinct genomic losses and gains were observed that appear to segregate Caucasian women with stage I disease from African American women with stage I disease and African American or Caucasian women with stage IIIC/IV disease. Conclusions: The GOG-210 bank yielded high quality DNA for detecting and mapping CNAs in frozen primary tumors with high resolution. Our results would imply that racial disparity for AA EEC has a genetic basis regardless of stage. Validation studies are currently underway in two endometrial cancer TMAs.

Abstract
PURPOSE To determine the maximum tolerated dose (MTD) of gemcitabine followed by cisplatin that can be administered weekly during pelvic radiation therapy in patients with locally advanced cervical cancer. METHODS A phase I and feasibility study with dose escalation of gemcitabine in cohorts of three to six patients to determine the MTD (the dose level at which no more than one of six patients experienced a acute dose-limiting toxicity) was conducted. RESULTS Thirteen patients were entered on the phase I trial. Acute dose-limiting toxicity occurred with weekly cisplatin at a dose of 40 mg/m(2) and gemcitabine at a dose of 100 mg/m(2). The study was modified, decreasing the dose of cisplatin to 30 mg/m(2) in an effort to dose escalate gemcitabine. Acute dose-limiting toxicity occurred again with weekly cisplatin at a dose of 30 mg/m(2) and gemcitabine at a dose of 75 mg/m(2) (dose level 3). In addition to acute hematologic and acute and late non-hematologic toxicities, late grade 3 and 4 GI and GU toxicities have occurred in two of six patients at dose level 3. Twelve of thirteen patients remained disease-free following treatment. CONCLUSION The MTD found in this chemoradiation study was weekly gemcitabine 50 mg/m(2) followed by cisplatin 40 mg/m(2). The alternative drug sequence has been reported by others to allow higher doses of gemcitabine. However, at this dose level chronic toxicity was observed. Further expansion of the feasibility cohort of this study was suspended pending the efficacy and toxicity results of a large trial which has recently been completed.

Abstract
5579 Introduction: Trabectedin is a DNA minor groove binding drug with a distinct MoA under development in sarcoma, prostate, breast and ROC. We have performed a pooled analysis of efficacy and tolerability of all phase II trials with T as 2nd - 3rd line in ROC. Methods: Three Trabectedin schedules were investigated: two every 3weeks (q3w; A: 1.3 mg/m2 3-h or B: 1.5 mg/m2 24-h) and one weekly (C: 0.58 mg/m2 3-h ×3 q4w). Endpoints were response rate (RR), time to progression (TTP), response duration (RD) and safety. 294 patients from 3 phase II (one randomized A vs B) trials were included: 108 were resistant (R) and 186 sensitive (S) to last platinum, based on progression-free interval <6 months or longer.Results: Overall RR and median TTP were 8% and 2.1mo in R and 34% and 5.8 mo in S patients. Median RD was 5.8 m. Schedules A & B q3w showed significant better RR (33% vs 16%, p=<0.0001) and median TTP (5.8 vs 2.8 m, p=0.0001) than the weekly schedule C. No efficacy difference was seen between 3-h and 24-h q3wk. In patients with = 2 prior platinum-based regimens, RR (R:7% and S:37%) and median TTP (R: 2.5 m and S:6.3 m) were similar than patients with only 1 prior platinum [RR (R:9%; S:33%) and TTP (R: 2 m; S: 5.5 m)]. 1,404 cycles were delivered [median A: 5(1–23), B: 5(1–19), C: 3(1–22)], with similar dose intensity (mg/m2/wk) across regimens (0.38, 0.42, 0.39). Most common drug-related AEs of any grade by cycle were (A, B, C) fatigue: 38, 35, 63% and vomiting: 16, 27, 21%. Grade 3/4 lab abnormalities were non-cumulative neutropenia: 21, 28, 1% and ALT increase: 32, 26, 3%. Low incidence of febrile neutropenia, neurotoxicity, stomatitis and alopecia was seen regardless of schedule. Conclusions: Trabectedin as single agent has shown clinical activity in both R and, particularly in S ROC. Activity was fully retained in patients with =2 prior platinum lines. Trabectedin q3w schedules (with no difference between 3 and 24-h) showed higher efficacy than T weekly. Toxicities were manageable and non-cumulative. Trabectedin is a promising new drug for the treatment of ROC and is under evaluation in a phase III trial. No significant financial relationships to disclose.

Abstract
5516 Background: There are few effective therapies for women with advanced or recurrent endometrial cancer. Targeted therapies such as AP23573, a novel mTOR inhibitor, may result in clinical benefit with fewer side effects. Preliminary results of a trial of single agent AP23573 in patients with progressive endometrial cancer who may have had up to 2 prior regimens of cytotoxic chemotherapy are reported. Methods: The trial is an open-label, Simon 2-stage, single-arm study enrolling patients who have advanced endometrial cancer with documented progression in the 3 months prior to entry. Patients receive 12.5mg AP23573 QDx5 as a 30-min. intravenous infusion every other week for 28-day cycles. The primary efficacy endpoint is Clinical Benefit Response (CBR), defined as a complete or partial response or prolonged stable disease (= 16 weeks) by modified RECIST guidelines. Results: Seven of the first 19 patients achieved CBR, allowing expansion to the second stage. Enrollment is now complete (45 patients). Demographic data are available for 35 (median 66 yrs.; range 46–89) patients who received treatment: 23 adenocarcinomas, 5 carcinosarcomas, 6 papillary serous carcinomas (UPSC) and 1 clear cell carcinoma. Thirty-four patients had prior chemotherapy including doxorubicin, taxanes or platinum agents. Fourteen of the 26 patients with available history had prior pelvic radiotherapy. Nine of 27 (33%) patients evaluable for response had CBRs, including 2 partial responses (PRs). One CBR had UPSC, the remaining patients, including the PRs, had adenocarcinomas. Seven of the patients achieving CBR are still on treatment. Eighteen of the 27 patients discontinued treatment before 4 cycles because of progressive disease (14), consent withdrawal (1) or unrelated adverse events (3). Adverse event data are available for 27 patients. The most common adverse events are fatigue, anemia (33% each), mouth sores and nausea/vomiting (30% each). There have been 16 grade 3/ 4 treatment related adverse events (2 hyperglycemia, 14 separate events similar to those reported in other AP23573 trials). Conclusions: AP23573 shows encouraging single-agent activity in pretreated patients with advanced, progressive endometrial cancer and is well tolerated. No significant financial relationships to disclose.

Abstract
BACKGROUND The effect of using fixed versus weight-based doses for erythropoietic agents has not been reported previously. To investigate this issue, the authors conducted a randomized Phase II study of darbepoetin alfa administered as either a fixed dose or a weight-based dose using an accelerated correction and maintenance dosing regimen (front-loading). METHODS During the correction phase, patients with anemia (hemoglobin < 11.0 g/dL) who had nonmyeloid malignancies and who were receiving chemotherapy were given darbepoetin alfa at a fixed dose of 325 microg (n = 122) or at a weight-based dose of 4.5 microg/kg (n = 120) once weekly until they achieved a hemoglobin concentration > or = 12.0 g/dL. Patients then received darbepoetin alfa (325 microg or 4.5 microg/kg) once every 3 weeks for the remainder of the 16-week treatment period (maintenance phase). RESULTS Darbepoetin alfa resulted in high Kaplan-Meier rates of hematopoietic response (> or = 2 g/dL increase from the baseline level or a hemoglobin level > or = 12 g/dL) in both the fixed-dose group (86%; 95% confidence interval [95% CI], 78- 94%) and the weight-based dose group (84%; 95% CI, 76-92%). The median time to hematopoietic response was 34 days (95% CI, 28-44 days) for the fixed-dose group and 36 days (95% CI, 30-45 days) for the weight-based dose group. Hemoglobin concentrations were maintained at target levels for up to 16 weeks in both groups. Darbepoetin alfa was well tolerated, and no clinically significant differences between fixed doses and weight-based doses were observed. CONCLUSIONS Darbepoetin alfa was effective when administered as either a fixed dose or a weight-based dose using a front-loading approach to rapidly correct anemia and effectively maintain hemoglobin levels in patients with anemia who had malignant disease.

Abstract
BACKGROUND We are reporting on a case of platinum-refractory low-grade ovarian cancer responding to treatment with an allogeneic bone marrow transplantation from an unrelated donor. CASE The 37-year-old patient received a preparative regimen consisting of fludarabine 25 mg/m(2) on days -6, -5, -4, -3 and -2, melphalan 70 mg/m(2) on days -3 and -2, and thymoglobulin 2 mg/kg on days -3, -2 and -1. An unrelated HLA-compatible bone marrow was infused on day 0. Graft-versus-host disease prophylaxis consisted of tacrolimus and methotrexate. The patient demonstrated complete donor chimerism. Serial CT scans of the abdomen and pelvis over the following 15 months showed a slow regression of the malignant lesion. CONCLUSION Engraftment of an unrelated donor marrow was achieved in a patient with ovarian cancer and induced a tumor response. This suggests the presence of a graft-versus-tumor effect in ovarian cancer. Further study is underway.

Abstract
The aim of this paper was to evaluate the factors that predict regression of untreated CIN 2 and 3. A total of 93 patients with colposcopic persistent CIN 2 and 3 lesions after biopsy were followed for 6 months. Human papillomavirus (HPV) types were determined by polymerase chain reaction at enrolment. We analysed the biologic and demographic predictors of natural regression using univariate and multivariate methods. The overall regression rate was 52% (48 out of 93), including 58% (22 out of 38) of CIN 2 and 47% (26 out of 55) of CIN 3 lesions (P=0.31 for difference). Human papillomavirus was detected in 84% (78 out of 93) of patients. In univariate analysis, 80% (12 out of 15) of lesions without HPV regressed compared to 46% (36 out of 78) of lesions with HPV infection (P=0.016). Women without HPV and those who had a resolution of HPV had a four-fold higher chance of regression than those with persistent HPV (relative odds=3.5, 95% CI=1.4-8.6). Women with five or fewer lifetime sexual partners had higher rates of regression than women with more than five partners (P=0.003). In multivariate analysis, HPV status and number of sexual partners remained as significant independent predictors of regression. In conclusion, HPV status and number of lifetime sexual partners were strongly predictive of regression of untreated CIN 2 and 3.

OBJECTIVE The goal of this work was to review patients with early-stage cervical cancer undergoing radical hysterectomy, comparing Pfannenstiel and vertical midline incisions for surgical feasibility, complications, and length of stay. METHODS Patients were identified by searching our institutional database. Data were collected from review of each patient's medical record, including demographics, cancer stage, histology, procedural information, length of stay, and complications. Associations between variables were studied using chi(2) and two-tailed t tests. Multivariate analysis was performed using logistic regression. RESULTS Between March 1996 and June 2000, 113 patients from the University and Presbyterian Hospitals, Oklahoma City, Oklahoma, underwent radical hysterectomy and pelvic and paraortic lymph node dissection with records available for review. Group 1 consisted of 40 patients who had vertical incisions and group 2 consisted of 73 patients who had Pfannenstiel incisions. There was no difference in race, number of previous abdominal surgeries, distribution of stage, histology, percentage of type III hysterectomies, estimated blood loss, nodal counts, pathologic margin positivity, and postoperative complications among the two groups. Group 2 were younger (41.6 vs 46.5, P = 0.02) and had a lower average QI than group 1 (24.9 vs 28.9, P = 0.001). Group 2 also had a shorter average hospital stay (4.6 days vs 5.8 days, P = 0.04) and shorter operative time (215 min vs 273 min, P = 0.09). Multivariate analysis resulted in Pfannenstiel incisions (P = 0.002), younger age (P = 0.004), and smaller body mass index (P = 0.01) being significant predictors of length of stay. CONCLUSIONS Pfannenstiel incisions are feasible without increased morbidity and equal nodal retrieval as compared with vertical midline incisions in patients with early-stage cervical cancer. Pfannenstiel incisions may offer an advantage besides cosmesis in the form of shorter operating room time and earlier discharge from the hospital.

Abstract
This paper describes the design and development of a high-resolution pressure sensor for use in the field of foot pressure measurement. The device uses an interferometry technique that involves the use of a laser light directed onto a pressure sensitive plate. The pressure plate compresses when a load is applied, and it is this compression which is measured by the interferometry technique. The interference pattern (interferogram) produced represents the pressure distribution across the plate. The interferogram is inputted into the computer using a high pixel CCD camera and video capture card. A fringe analysis program then converts the interferogram into a three-dimensional image of the pressure distribution. A prototype system is described and the initial results show that the system can produce a high resolution image with dynamic capabilities.

Abstract
Since the establishment of extraovarian peritoneal serous papillary carcinoma (EPSPC) as a clinical entity in 1959, less than 250 cases have been described and its clinicopathologic features remain obscure. The present series is a retrospective, case-controlled study comparing the response and survival to cytoreductive surgery followed by cisplatin-based multiagent chemotherapy of 33 women with confirmed EPSPC versus 33 cases with papillary serous ovarian cancer (PSOC). Each EPSPC case was matched to a PSOC control for extent and distribution of disease prior to and following cytoreductive surgery, tumor grade, patient age, and treatment. Additionally, the new Gynecologic Oncology Group criteria for the diagnosis for EPSPC are discussed. There were no significant differences in tumor response to therapy, disease-free interval, and actuarial survival between cases and controls. These data suggest that EPSPC is clinically similar to PSOC and support the need for a prospective clinical trial to compare these two entities further.
