Abstract
OBJECTIVES Clear cell carcinoma is a high-risk subtype of endometrial cancer. Some patients have a mixture of clear cell carcinoma with other histologic types (endometrioid or serous) or cannot be neatly assigned to one of these types. Protocol GOG-8032 within GOG-210 was designed to determine whether these tumors differ from pure clear cell carcinoma in stage at diagnosis, initial pattern of spread, or patient survival. METHODS The term "mixed" was applied to tumors with multiple identifiable components, and "indeterminate" was applied to tumors with features intermediate between different histologic types. Three hundred eleven women with pure, mixed, or indeterminate clear cell carcinoma were identified in a larger cohort of patients undergoing hysterectomy for endometrial cancer in GOG-210. Histologic slides were centrally reviewed by expert pathologists. Baseline and follow-up data were analyzed. RESULTS One hundred thirty-six patients had pure clear cell carcinoma and 175 had a mixed or indeterminate clear cell pattern. Baseline clinicopathologic characteristics were similar except for a small difference in age at presentation. Univariate survival analysis confirmed the significance of typical endometrial cancer prognostic factors. Patients in the mixed categories had disease-free and overall survival similar to pure clear cell carcinoma, but the indeterminate clear cell/endometrioid group had longer survival. CONCLUSION In clear cell endometrial cancer, the presence of a definite admixed endometrioid or serous component did not correlate with a significant difference in prognosis. Patients whose tumors had indeterminate clear cell features had better prognosis. Some of these tumors may be endometrioid tumors mimicking clear cell carcinoma.

Abstract
OBJECTIVE Vulvar necrotising fasciitis (VNF) is a severe soft tissue infection associated with substantial morbidity and high mortality. At Stony Brook Medicine, US, patients with known or suspected VNF are treated by a structured multidisciplinary team consisting of members of the Departments of Emergency Medicine and Medicine, the Divisions of Gynecologic Oncology, Burn and Surgical Intensive Care Units, Infectious Disease and Plastic Surgery, and the nursing, nutrition, physical/occupational therapy and social work services. METHOD This is a retrospective review of patients presenting to Stony Brook University Hospital with VNF over an 18-month period. RESULTS A total of 10 patients were treated for VNF during the study period. All patients were treated by the structured multidisciplinary team, including extensive initial surgical debridement by the gynaecologic oncologists. All patients survived to discharge. CONCLUSION The results of this review demonstrated that prompt diagnosis, rapid implementation of appropriate antibiotic coverage, surgical debridement of necrotic tissue, and comprehensive care delivered by a structured multidisciplinary team contributed to positive clinical outcomes and decreased the risk of death from VNF.

Abstract
PURPOSE This surgical window of opportunity (window) study assessed the short-term effect of medroxyprogesterone acetate (MPA) alone versus MPA plus the histone deacetylase (HDAC) inhibitor entinostat on regulation of progesterone receptor (PR) in women with newly diagnosed endometrioid endometrial adenocarcinoma. PATIENTS AND METHODS This multisite, randomized, open-label surgical window study treated women intramuscularly on day 1 with 400 mg MPA. Entinostat given 5 mg by mouth on days 1, 8, and 15 was randomly assigned with equal probability. Surgery followed on days 21-24. Pretreatment and posttreatment tissue was assessed for PR H-scores, Ki-67 levels, and histologic response. RESULTS Fifty patients were accrued in 4 months; 22 and 20 participants had PR evaluable pretreatment and posttreatment slides in the MPA and MPA/entinostat arms, respectively. Median posttreatment PR H-scores were significantly lower than pretreatment H-scores in both arms but did not differ significantly (MPA: 247 vs. 27, MPA/entinostat 260 vs. 23, respectively, P = 0.87). Decreased Ki-67 was shown in 90% treated with MPA/entinostat compared with 68% treated with MPA alone (P = 0.13). Median PR H-score decreases were larger when Ki-67 was decreased (208) versus not decreased (45). The decrease in PR pretreatment versus posttreatment was associated with loss of Ki-67 nuclear staining, consistent with reduced cellular proliferation (P < 0.008). CONCLUSIONS This surgical window trial rapidly accrued in a multisite setting and evaluated PR as its primary endpoint and Ki-67 as secondary endpoint. Despite no immediate effect of entinostat on PR in this short-term study, lessons learned can inform future window and treatment trials.

Abstract
OBJECTIVE While most cases of endometrial cancer can readily be classified as pure endometrioid, pure serous, or another type, others show an apparent mixture of serous and endometrioid components, or indeterminate serous versus endometrioid features. Since serous histology carries a worse prognosis than endometrioid, Gynecologic Oncology Group protocol GOG-8032 was established to examine whether the presence of a non-serous component is a favorable feature in an otherwise serous cancer. METHODS 934 women with serous cancer were prospectively identified among a larger group enrolled in GOG-0210. Six expert gynecologic pathologists classified each case as pure serous (SER, n=663), mixed serous and endometrioid (SER-EM-M, n=138), or indeterminate serous v. endometrioid (SER-EM-I, n=133) by H&E morphology. Follow-up data from GOG-0210 were analyzed. RESULTS The subgroups did not differ on BMI, race, ethnicity, lymphovascular invasion, cervical invasion, ovary involvement, peritoneal involvement, omental involvement, FIGO stage, or planned adjuvant treatment. SER-EM-M patients were younger (p=0.0001) and less likely to have nodal involvement (p=0.0287). SER patients were less likely to have myoinvasion (p=0.0002), and more likely to have adnexal involvement (p=0.0108). On univariate analysis, age, serous subtype, race, and components of FIGO staging predicted both progression-free and overall survival. On multiple regression, however, serous subtype (SER, SER-EM-M, or SER-EM-I) did not significantly predict survival. CONCLUSIONS There were few clinicopathologic differences between cases classified as SER, SER-EM-M, and SER-EM-I. Cases with a mixture of serous and endometrioid morphology, as well as cases with morphology indeterminate for serous v. endometrioid type, had the same survival as pure serous cases.

Abstract
The purpose of this study was to determine which patient- or surgery-related factors are predictive of need for perioperative transfusion to avoid obtaining unnecessary pre-operative type and screens (T&S). We conducted an observational retrospective cohort study of 1200 women ≥ 18 years old undergoing gynecologic surgery for benign, possibly benign, or malignant indications on a gynecologic oncology service at a university medical center from 2009-2016. A logistic regression model was used to examine patient-related and surgery-related variables predictive of outcome of transfusion. Independent variables included patient demographics, comorbidities, and surgical indication surgical route, and surgical type. Dependent variable was transfusion outcome (T&S only, conversion to type and cross (T&C), or transfusion). Eight hundred ninety-nine (74.9%) women underwent pre-operative T&S, of which 118 (9.8%) were converted to T&C, and 80 (6.7%) received a transfusion of blood or blood products. Cancer indication, major surgery, and preoperative hematocrit less than 36% were significantly associated with need for transfusion (P = 0.002, P < 0.0001, P < 0.0001, respectively). Patients with a benign indication undergoing minor procedures and with normal preoperative hematocrit are least likely to require transfusion.

Abstract
PURPOSE Limitations of the paclitaxel-doxorubicin-cisplatin (TAP) regimen in the treatment of endometrial cancer include tolerability and cumbersome scheduling. The Gynecologic Oncology Group studied carboplatin plus paclitaxel (TC) as a noninferior alternative to TAP. METHODS GOG0209 was a phase III, randomized, noninferiority, open-label trial. Inclusion criteria were stage III, stage IV, and recurrent endometrial cancers; performance status 0-2; and adequate renal, hepatic, and marrow function. Prior radiotherapy and/or hormonal therapy were permitted, but chemotherapy, including radiosensitization, was not. Patients were treated with doxorubicin 45 mg/m2 and cisplatin 50 mg/m2 (day 1), followed by paclitaxel 160 mg/m2 (day 2) with granulocyte colony-stimulating factor or paclitaxel 175 mg/m2 and carboplatin area under the curve 6 (day 1) every 21 days for seven cycles. The primary endpoint was overall survival (OS; modified intention to treat). Progression-free survival (PFS), health-related quality of life (HRQoL), and toxicity were secondary endpoints. RESULTS From 2003 to 2009, 1,381 women were enrolled. Noninferiority of TC to TAP was concluded for OS (median, 37 v 41 months, respectively; hazard ratio [HR], 1.002; 90% CI, 0.9 to 1.12), and PFS (median, 13 v 14 months; HR, 1.032; 90% CI, 0.93 to 1.15). Neutropenic fever was reported in 7% of patients receiving TAP and 6% of those receiving TC. Grade > 2 sensory neuropathy was recorded in 26% of patients receiving TAP and 20% receiving TC (P = .40). More grade ≥ 3 thrombocytopenia (23% v 12%), vomiting (7% v 4%), diarrhea (6% v 2%), and metabolic (14% v 8%) toxicities were reported with TAP. Neutropenia (52% v 80%) was more common with TC. Small HRQoL differences favored TC. CONCLUSION With demonstrated noninferiority to TAP, TC is the global first-line standard for advanced endometrial cancer.

Abstract
To isolate circulating tumor cells (CTC) from women with advanced cervical cancer and estimate the impact of CTCs and treatment on overall survival and progression-free survival (PFS). A total of 7.5 mL of whole blood was drawn pre-cycle 1 and 36 days post-cycle 1 from patients enrolled on Gynecologic Oncology Group 0240, the phase III randomized trial that led directly to regulatory approval of the antiangiogenesis drug, bevacizumab, in women with recurrent/metastatic cervical cancer. CTCs (defined as anti-cytokeratin+/anti-CD45- cells) were isolated from the buffy coat layer using an anti-EpCAM antibody-conjugated ferrofluid and rare earth magnet, and counted using a semiautomated fluorescence microscope. The median pre-cycle 1 CTC count was 7 CTCs/7.5 mL whole blood (range, 0-18) and, at 36 days posttreatment, was 4 (range, 0-17). The greater the declination in CTCs between time points studied, the lower the risk of death [HR, 0.87; 95% confidence interval (CI), 0.79-0.95)]. Among patients with high (≥ median) pretreatment CTCs, bevacizumab treatment was associated with a reduction in the hazard of death (HR, 0.57; 95% CI, 0.32-1.03) and PFS (HR, 0.59; 95% CI, 0.36-0.96). This effect was not observed with low (< median) CTCs. CTCs can be isolated from women with advanced cervical cancer and may have prognostic significance. A survival benefit conferred by bevacizumab among patients with high pretreatment CTCs may reflect increased tumor neovascularization and concomitant vulnerability to VEGF inhibition. These data support studying CTC capture as a potential predictive biomarker.

Abstract
Background Humeral retroversion (RV) is important to the study of shoulder function and reconstruction. This study tests the hypothesis that clinically obtained computer tomography (CT) measurements for humeral RV (off-axis measurements) differ from those obtained after reformatting the image slice orientation so that the humeral shaft is perpendicular to the gantry (coaxial measurements) and explores deviations from true RV. Materials and methods A custom-built application created in Mathematica was used to explore the effect of altering the humeral orientation on slice angle acquisition by 3D imaging technologies, on the perceived angle of RV from the 2D-projection of the reference axes. The application allows for control of humeral axis orientation relative to image slice (3D) or plain of projection (2D) and humeral rotation. The effect of rotating a virtual model of one humerus around its own axis and in discrete anatomical directions on the measured RV angle was assessed. Results The coaxial measurement of humeral RV (31.2°) differed from off-axis measurement, with a maximum difference in measured RV of 50° in 45° of extension. The typical position of the humerus in a CT scan resulted in a difference in RV measurement up to 22°. Explorations of deviation led to the following outcomes, as divided by anatomic direction. Extension and abduction led to an underestimation, and flexion and adduction led to an overestimation of the RV-angle. Conclusion Measurements must be done consistently about the position and orientation of the humerus. Deviation in the humeral alignment of as little as 10° can distort the measurement of version up to 15°. How to cite this article van de Bunt F, Pearl ML, van Noort A.

Abstract
Importance Ovarian cancer is the leading cause of gynecologic cancer deaths in the United States. Pazopanib is an oral, multitarget kinase inhibitor of vascular endothelial growth factor receptors 1, 2, and 3; platelet-derived growth factor receptors α and β; and proto-oncogene receptor tyrosine kinase (c-KIT). Objective To estimate the progression-free survival (PFS) hazard ratio (HR) of weekly paclitaxel and pazopanib compared with weekly paclitaxel and placebo in women with recurrent ovarian cancer. Secondary objectives included frequency and severity of adverse events, proportion responding, and overall survival (OS) in each arm. Translational research objectives included exploring the association between possible biomarkers and single-nucleotide polymorphisms in vascular endothelial growth factor A, interleukin 8, and hypoxia-inducible factor 1α; and PFS, OS, and proportion responding. Design, Setting, and Participants A randomized, placebo-controlled, double-blind phase 2 study was conducted at 26 participating institutions. Patients were enrolled between December 12, 2011, and April 22, 2013. Data were frozen on August 11, 2014. Participants were patients with persistent or recurrent epithelial ovarian, fallopian tube, or primary peritoneal carcinoma with 1 to 3 prior regimens and performance status of 0 to 2. One hundred six patients enrolled; 100 were evaluable for toxic effects. Interventions All patients received paclitaxel 80 mg/m2 intravenously on days 1, 8, and 15 every 28 days and were randomized 1:1 to pazopanib 800 mg orally daily or placebo. Main Outcomes and Measures The primary end point was PFS. The study was designed to detect a 37.5% reduction in the hazard with 80% power (α = 10%). Results A total of 106 women (median age [range], 61 [35-87] years; 88 [83%] white) were enrolled. Study arms were well balanced for age, performance status, measurable disease, and prior bevacizumab. Proportion responding was 14 of 44 (31.8%) vs 10 of 44 (22.7%) for pazopanib plus paclitaxel vs paclitaxel alone. Median PFS was 7.5 vs 6.2 months for pazopanib plus paclitaxel vs paclitaxel alone, respectively (HR, 0.84; 90% CI, 0.57-1.22; P = .20). Median OS was 20.7 vs 23.3 months for pazopanib plus paclitaxel vs paclitaxel alone (HR, 1.04; 90% CI, 0.60-1.79; P = .90). Severe hypertension was more common on the pazopanib plus paclitaxel arm (relative risk, 12.0; 95% CI, 1.62-88.84). More patients discontinued treatment on the paclitaxel arm for disease progression (34 of 52 [65.4%] vs 17 of 54 [31.5%]), and more on the pazopanib plus paclitaxel arm for adverse events (20 of 54 [37%] vs 5 of 52 [9.6%]). No association was found between single-nucleotide polymorphisms (interleukin 8 and hypoxia-inducible factor 1α) and OS and proportion responding. Patients with VEGFA CC genotype may be more resistant to weekly paclitaxel than those with the AC or AA genotype, with 1 of 14 (7%), 3 of 15 (20%), and 4 of 8 (50%) responding, respectively. Conclusions and Relevance The combination of pazopanib plus paclitaxel is not superior to paclitaxel in women with recurrent ovarian cancer.

Abstract
Circulating tumor cells (CTCs) are important clinical indicators of metastatic progression and treatment efficacy. However, because of their low number and heterogeneity, reliable patient-derived CTC models are not readily available. We report here the isolation and characterization of the invasive population of CTCs, iCTCs, from blood of 10 patients with epithelial ovarian cancer (EOC) and one pancreatic cancer patient based on the avidity of tumor cells toward an artificial collagen-based adhesion matrix (CAM), in comparison with tumor progenitor (TP) cells isolated from tumor cell lines, tumors and ascites from EOC patients. CAM-avid cells identified to be iCTCs were indistinguishable with TP cells using either functional CAM uptake or surface markers (seprase and CD44). In addition, iCTCs were characterized using peritoneal and spontaneous metastasis models in vivo to evaluate their metastatic propensity and therapeutic response. TP cells and iCTCs had a doubling time of about 34-42 hours. TP cells were rare (<3.5%) in most patient-derived specimens, however, iCTCs emigrated into blood, at a high frequency, 64.2% (n = 49). Approximately 500 patient-derived iCTCs recapitulated formation of iCTCs in mouse blood and formed micrometastases in the liver and/or lung, a degree of metastatic spread equivalent to the inoculation of 5 × 105 bulk tumor cells isolated from ascites and tumors. iCTCs were shown to be novel therapeutic targets for blocking metastasis using the reduced formation of iCTCs and micrometastases by RNAi, peptides, and monoclonal antibodies against seprase.

Abstract
AIM To examine humeral retroversion in infants who sustained brachial plexus birth palsy (BPBI) and suffered from an internal rotation contracture. Additionally, the role of the infraspinatus (IS) and subscapularis (SSc) muscles in the genesis of this bony deformation is explored.
METHODS Bilateral magnetic resonance imaging (MRI) scans of 35 infants (age range: 2-7 mo old) with BPBI were retrospectively analyzed. Retroversion was measured according to two proximal axes and one distal axis (transepicondylar axis). The proximal axes were: (1) the perpendicular line to the borders of the articular surface (humeral centerline); and (2) the longest diameter through the humeral head. Muscle cross-sectional areas of the IS and SSc muscles were measured on the MRI-slides representing the largest muscle belly. The difference in retroversion was correlated with the ratio of muscle-sizes and passive external rotation measurements.
RESULTS Retroversion on the involved side was significantly decreased, 1.0° vs 27.6° (1) and 8.5° vs 27.2° (2), (P < 0.01), as compared to the uninvolved side. The size of the SSc and IS muscles on the involved side was significantly decreased, 2.26 cm² vs 2.79 cm² and 1.53 cm² vs 2.19 cm², respectively (P < 0.05). Furthermore, the muscle ratio (SSc/IS) at the involved side was significantly smaller compared to the uninvolved side (P = 0.007).
CONCLUSION Even in our youngest patient population, humeral retroversion has a high likelihood of being decreased. Altered humeral retroversion warrants attention as a structural change in any child being evaluated for the treatment of an internal rotation contracture.

Abstract
BACKGROUND Black women with endometrial cancer are more likely to die of their disease compared with white women with endometrial cancer. These survival disparities persist even when disproportionately worse tumor characteristics among black women are accounted. Receipt of less complete adjuvant treatment among black patients with endometrial cancer could contribute to this disparity. OBJECTIVE We assessed the hypothesis that black women with endometrial cancer are less likely than their white counterparts to receive adjuvant treatment within subgroups defined by tumor characteristics in the NRG Oncology/Gynecology Oncology Group 210 Study. STUDY DESIGN Our analysis included 615 black and 4283 white women with endometrial cancer who underwent hysterectomy. Women completed a questionnaire that assessed race and endometrial cancer risk factors. Tumor characteristics were available from pathology reports and central review. We categorized women as low-, intermediate-, or high-risk based on the European Society for Medical Oncology definition. Adjuvant treatment was documented during postoperative visits and was categorized as no adjuvant treatment (54.3%), radiotherapy only (16.5%), chemotherapy only (15.2%), and radiotherapy plus chemotherapy (14.0%). We used polytomous logistic regression to estimate odds ratios and 95% confidence intervals for multivariable-adjusted associations between race and adjuvant treatment in the overall study population and stratified by tumor subtype, stage, or European Society for Medical Oncology risk category. RESULTS Overall, black women were more likely to have received chemotherapy only (odds ratio, 1.40; 95% confidence interval, 1.04-1.86) or radiotherapy plus chemotherapy (odds ratio, 2.01; 95% confidence interval, 1.54-2.62) compared with white women in multivariable-adjusted models. No racial difference in the receipt of radiotherapy only was observed. In tumor subtype-stratified models, black women had higher odds of receiving radiotherapy plus chemotherapy than white women when diagnosed with low-grade endometrioid (odds ratio, 2.04; 95% confidence interval, 1.06-3.93) or serous tumors (odds ratio, 1.81; 95% confidence interval, 1.07-3.08). Race was not associated with adjuvant treatment among women who had been diagnosed with other tumor subtypes. In stage-stratified models, we observed no racial differences in the receipt of adjuvant treatment. In models that were stratified by European Society for Medical Oncology risk group, black women with high-risk cancer were more likely to receive radiotherapy plus chemotherapy compared with white women (odds ratio, 1.41; 95% confidence interval, 1.03-1.94). CONCLUSION Contrary to our hypothesis, we observed higher odds of specific adjuvant treatment regimens among black women as compared with white women within specific subgroups of endometrial cancer characteristics.

Abstract
BACKGROUND Off-track Hill-Sachs lesions have been associated with high rates of recurrent shoulder instability. Both arthroscopic Bankart with remplissage and modified Latarjet have been described to treat off-track Hill-Sachs lesions. However, few comparative studies exist between the 2 techniques in heterogeneous populations. HYPOTHESIS Remplissage would have similar recurrence rates and clinical outcomes to modified Latarjet for off-track Hill-Sachs lesions with subcritical glenoid bone loss. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Between 2005 and 2015, 189 patients with recurrent anterior shoulder instability, off-track Hill-Sachs lesion, and less than 25% glenoid bone loss were identified. Arthroscopic Bankart with remplissage (group A) was performed in 98 patients, and modified Latarjet (group B) was performed in 91 patients. Surgeries were performed by multiple fellowship-trained surgeons at 2 centers. The mean follow-up time was 3.2 years. Patients were assessed for their risk of recurrence using the Instability Severity Index Score and had preoperative 3-dimensional imaging to assess humeral and glenoid bone loss, along with measurement of the glenoid track. Single Assessment Numeric Evaluation (SANE), Western Ontario Shoulder Instability Index (WOSI), visual analog scale (VAS) for pain, range of motion, recurrence rate, subsequent procedures, and complications were analyzed. RESULTS When comparing the remplissage and Latarjet groups, the remplissage group had a higher VAS pain score (2.2 vs 1.55, P = .041) and less internal rotation motion in abduction (40.9° vs 53.2°, P = .006). The complication rate was higher in the Latarjet group (12.1% vs 1%, P = .002). There was no difference between the 2 groups in patient-reported outcomes, such as WOSI and SANE. In addition, there was no difference between the 2 groups in revision rate and episodes of recurrent instability. In subgroup univariate analysis of revision patients, the remplissage group had higher VAS pain score (3.6 vs 2.2, P = .001), higher recurrence rate (34.8% vs 10.3%, P = .042), higher revision rate (43.5% vs 15.4%, P = .019), and lower complication rate (4.35% vs 28.2%, P = .024). For patients with >15% glenoid bone loss, Latarjet had lower recurrence rate (6.06% vs 28.6%, P = .034) and lower revision rate (3.03% vs 21.4%, P = .041). In collision and contact athletes, Latarjet had better WOSI scores (138 vs 231, P = .019) and lower recurrence rate (30% vs 0%, P = .005). In multivariate analysis, the odds of recurrence in the remplissage group were higher than in the Latarjet group in patients with previous instability surgery (3.56, P = .006), collision and contact athletes (2.37, P = .02), those with 10% to 15% glenoid bone loss (1.28, P = .04), and those with >15% glenoid bone loss (6.48, P = .001). CONCLUSION For off-track Hill-Sachs lesions with subcritical glenoid bone loss, both the remplissage and modified Latarjet can achieve satisfactory results with the initial surgical intervention in the general population, but a higher complication rate was observed in the Latarjet group. However, Latarjet appears to be a better choice in patients with revision instability surgery, collision and contact athletes, and those with >10% glenoid bone loss.

Abstract
OBJECTIVES The purpose of this study was to assess the prognostic significance of a simplified, clinically accessible classification system for endometrioid endometrial cancers combining Lynch syndrome screening and molecular risk stratification. METHODS Tumors from NRG/GOG GOG210 were evaluated for mismatch repair defects (MSI, MMR IHC, and MLH1 methylation), POLE mutations, and loss of heterozygosity. TP53 was evaluated in a subset of cases. Tumors were assigned to four molecular classes. Relationships between molecular classes and clinicopathologic variables were assessed using contingency tests and Cox proportional methods. RESULTS Molecular classification was successful for 982 tumors. Based on the NCI consensus MSI panel assessing MSI and loss of heterozygosity combined with POLE testing, 49% of tumors were classified copy number stable (CNS), 39% MMR deficient, 8% copy number altered (CNA) and 4% POLE mutant. Cancer-specific mortality occurred in 5% of patients with CNS tumors; 2.6% with POLE tumors; 7.6% with MMR deficient tumors and 19% with CNA tumors. The CNA group had worse progression-free (HR 2.31, 95%CI 1.53-3.49) and cancer-specific survival (HR 3.95; 95%CI 2.10-7.44). The POLE group had improved outcomes, but the differences were not statistically significant. CNA class remained significant for cancer-specific survival (HR 2.11; 95%CI 1.04-4.26) in multivariable analysis. The CNA molecular class was associated with TP53 mutation and expression status. CONCLUSIONS A simple molecular classification for endometrioid endometrial cancers that can be easily combined with Lynch syndrome screening provides important prognostic information. These findings support prospective clinical validation and further studies on the predictive value of a simplified molecular classification system.

Abstract
OBJECTIVE Endometrial cancer can be diagnosed early and cured, yet cases that recur portend a very poor prognosis with over 10,000 women succumbing to the disease every year. In this study we addressed the question of how to recognize cases likely to recur early in the course of therapy using dysregulation of tumor microRNAs (miRNAs) as predictors. METHODS Using the tissue collection from Gynecologic Oncology Group Study-210, we selected and analyzed expression of miRNAs in 54 recurrent and non-recurrent cases. The three most common histologic types, endometrioid adenocarcinoma (EEA), serous adenocarcinoma (ESA) and carcinosarcoma (UCS), were analyzed as three independent sets and their miRNA expression profiles compared. RESULTS Only one miRNA was statistically different between recurrent and non-recurrent cases, and in only one histologic type: significant down-regulation of miR-181c was observed in EEA recurrence. Using several well-known databases to assess miR-181c targets, one target of particular relevance to cancer, NOTCH2, was well supported. Using The Cancer Genome Atlas and our validation tumor panel from the GOG-210 cohort, we confirmed that NOTCH2 is significantly over-expressed in EEA. In the most relevant endometrial adenocarcinoma cell model, Ishikawa H, altering miR-181c expression produces significant changes in NOTCH2 expression, consistent with direct targeting. CONCLUSIONS Our findings suggest that increased NOTCH2 via loss of miR-181c is a significant component of EEA recurrence. This presents an opportunity to develop miR-181c and NOTCH2 as markers for early identification of high risk cases and the use of NOTCH inhibitors in the prevention or treatment of recurrent disease.

Abstract
Non-Hispanic black (NHB) women are more likely to experience an endometrial carcinoma (EC) recurrence compared to non-Hispanic white (NHW) women. The extent to which tumor characteristics, socioeconomic status (SES) and treatment contribute to this observation is not well defined. In the NRG Oncology/Gynecology Oncology Group (GOG) 210 Study we evaluated associations between race/ethnicity and EC recurrence according to tumor characteristics with adjustment for potential confounders. Our analysis included 3,199 NHW, 532 NHB and 232 Hispanic women with EC. Recurrence was documented during follow-up. We used Cox regression to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for associations between race/ethnicity and EC recurrence in models stratified by histologic subtype (low-grade endometrioid, high-grade endometrioid, serous, mixed cell, carcinosarcoma, clear cell) or stage (I, II, III) and adjusted for age, SES, body mass index, smoking status and treatment. In histologic subtype-stratified models, higher EC recurrence was noted in NHB women with low-grade endometrioid (HR = 1.94, 95% CI = 1.21-3.10) or carcinosarcomas (HR = 1.66, 95% CI = 0.99-2.79) compared to NHWs. In stage-stratified models, higher EC recurrence was noted among NHB women with stage I (HR = 1.48, 95% CI = 1.06-2.05) and Hispanic women with stage III disease (HR = 1.81, 95% CI = 1.11-2.95). Our observations of higher EC recurrence risk among NHB and Hispanic women, as compared to NHW women, were not explained by tumor characteristics, SES, treatment or other confounders. Other factors, such as racial differences in tumor biology or other patient factors, should be explored as contributors to racial disparities in EC recurrence.

Abstract
Background Recent data suggest that the use of nonsteroidal anti-inflammatory drugs (NSAIDs) may be associated with reductions in endometrial cancer risk, yet very few have examined whether their use is related to prognosis among endometrial cancer patients. Methods Study subjects comprised 4374 participants of the NRG Oncology/Gynecology Oncology Group 210 Study with endometrial carcinoma who completed a presurgical questionnaire that assessed history of regular prediagnostic NSAID use and endometrial cancer risk factors. Recurrences, vital status, and causes of death were obtained from medical records and cancer registries. Fine-Gray semiproportional hazards regression estimated adjusted subhazard ratios (HRs) and 95% confidence intervals (CIs) for associations of NSAID use with endometrial carcinoma-specific mortality and recurrence. Models were stratified by endometrial carcinoma type (ie, type I [endometrioid] vs type II [serous, clear cell, or carcinosarcoma]) and histology. Results Five hundred fifty endometrial carcinoma-specific deaths and 737 recurrences occurred during a median of five years of follow-up. NSAID use was associated with 66% (HR = 1.66, 95% CI = 1.21 to 2.30) increased endometrial carcinoma-specific mortality among women with type I cancers. Associations were statistically significant for former and current users, and strongest among former users who used NSAIDs for 10 years or longer (HR = 2.23, 95% CI = 1.19 to 4.18, two-sided P trend = .01). NSAID use was not associated with recurrence or endometrial carcinoma-specific mortality among women with type II tumors. Conclusions In this study, use of NSAIDs was associated with increased endometrial carcinoma-specific mortality, especially in patients with type I tumors. Barring a clear biologic mechanism by which NSAIDs would increase the risk of cause-specific mortality, cautious interpretation is warranted.

Abstract
PURPOSE Activating FGFR2 mutations have been identified in ~10% of endometrioid endometrial cancers (ECs). We have previously reported that mutations in FGFR2 are associated with shorter disease free survival (DFS) in stage I/II EC patients. Here we sought to validate the prognostic importance of FGFR2 mutations in a large, multi-institutional patient cohort. METHODS Tumors were collected as part of the GOG 210 clinical trial "Molecular Staging of Endometrial Cancer" where samples underwent rigorous pathological review and had more than three years of detailed clinical follow-up. DNA was extracted and four exons encompassing the FGFR2 mutation hotspots were amplified and sequenced. RESULTS Mutations were identified in 144 of the 973 endometrioid ECs, of which 125 were classified as known activating mutations and were included in the statistical analyses. Consistent with FGFR2 having an association with more aggressive disease, FGFR2 mutations were more common in patients initially diagnosed with stage III/IV EC (29/170;17%) versus stage I/II EC (96/803; 12%; p=0.07, Chi-square test). Additionally, incidence of progression (progressed, recurred or died from disease) was significantly more prevalent (32/125, 26%) among patients with FGFR2 mutation versus wild type (120/848, 14%; p<0.001, Chi-square test). Using Cox regression analysis adjusting for known prognostic factors, patients with FGFR2 mutation had significantly (p<0.025) shorter progression-free survival (PFS; HR 1.903; 95% CI 1.177-3.076) and endometrial cancer specific survival (ECS; HR 2.013; 95% CI 1.096-3.696). CONCLUSION In summary, our findings suggest that clinical trials testing the efficacy of FGFR inhibitors in the adjuvant setting to prevent recurrence and death are warranted.

Abstract
BACKGROUND Glenoid version and percentage of the humeral head anterior to the scapular line are commonly used 2-D measures to assess deformity of the glenohumeral joint of children with neonatal brachial plexus palsy. OBJECTIVE To assess whether glenoid version and percentage of the humeral head anterior to the scapular line would be altered by standardizing the measurements to the orientation of the scapula. MATERIALS AND METHODS Twenty-one bilateral magnetic resonance imaging (MRI) scans were evaluated by four reviewers. Measurements were performed on the axial image slices and again after applying 3-D reformatting. RESULTS Three-dimensional reformatting led to intrapatient corrections up to 25° for version and -30% for percentage of the humeral head anterior to the scapular line. The mean difference on the involved side between clinical and anatomical version across all subjects from all reviewers was 2.2° ± 3.9° (range: -4.5° to 11.5°). The mean difference in the percentage of the humeral head anterior to the scapular line after reformatting was -1.8% (range: -15.9% to 5.2%). CONCLUSION Measurements can differ greatly for the same child depending on technical factors of image acquisition and presentation in the clinical setting. With this study, we present a clinically accessible protocol to correct for scapular orientation from MRI data of children with neonatal brachial plexus palsy.

Abstract
Context: The overhand pitch is one of the fastest known human motions and places enormous forces and torques on the upper extremity. Shoulder and elbow pain and injury are common in high-level pitchers. A large body of research has been conducted to understand the pitching motion. Evidence Acquisition: A comprehensive review of the literature was performed to gain a full understanding of all currently available biomechanical and clinical evidence surrounding pitching motion analysis. These motion analysis studies use video motion analysis, electromyography, electromagnetic sensors, and markered motion analysis. This review includes studies performed between 1983 and 2016. Study Design: Clinical review. Level of Evidence: Level 5. Results: The pitching motion is a kinetic chain, in which the force generated by the large muscles of the lower extremity and trunk during the wind-up and stride phases are transferred to the ball through the shoulder and elbow during the cocking and acceleration phases. Numerous kinematic factors have been identified that increase shoulder and elbow torques, which are linked to increased risk for injury. Conclusion: Altered knee flexion at ball release, early trunk rotation, loss of shoulder rotational range of motion, increased elbow flexion at ball release, high pitch velocity, and increased pitcher fatigue may increase shoulder and elbow torques and risk for injury.

Abstract
BACKGROUND Synuclein-γ (SNCG) is highly expressed in advanced solid tumors, including uterine serous carcinoma (USC). The objective of the current study was to determine whether SNCG protein was associated with survival and clinical covariates using the largest existing collection of USCs from the Gynecologic Oncology Group (GOG-8023). METHODS High-density tissue microarrays (TMAs) of tumor tissues from 313 patients with USC were stained by immunohistochemistry for SNCG, p53, p16, FOLR1, pERK, pAKT, ER, PR, and HER2/neu. Associations of SNCG and other tumor markers with overall and progression-free survival were assessed using log-rank tests and Cox proportional-hazards models, which also were adjusted for age, race, and stage. RESULTS The overall survival at 5 years was 46% for women with high SNCG expression and 62% for those with low SNCG expression (log-rank P = .021; hazard ratio [HR], 1.31; 95% confidence interval [CI], 0.91-1.9 in adjusted Cox model). The progression-free survival rate at 5 years was worse for women who had high SNCG expression, at 40%, compared with 56% for those who had low SNCG expression (log-rank P = .0081; HR, 1.36; 95% CI, 0.96-1.92 in adjusted Cox model). High levels of both p53 and p16 were significantly associated with worse overall survival (p53: HR, 4.20 [95% CI, 1.54-11.45]; p16: HR, 1.95 [95% CI, 1.01-3.75]) and progression-free survival (p53: HR, 2.16 [95% CI, 1.09-4.27]; p16: HR, 1.53 [95% CI, 0.87-2.69]) compared with low levels. CONCLUSIONS This largest collection of USCs to date demonstrates that SNCG was associated with poor survival in univariate analyses. SNCG does not predict survival outcome independent of p53 and p16 in models that jointly consider multiple markers. Cancer 2017;123:1144-1155. © 2016 American Cancer Society.

Abstract
BACKGROUND The most common sequela of neonatal brachial plexus palsy is an internal rotation contracture of the shoulder that impairs function and leads to skeletal deformation of the glenohumeral joint. Treatment options include release, transfers, and humeral osteotomy, all ultimately striving for better function through increased external rotation. Prior studies have shown that neonatal brachial plexus palsy alters humeral retroversion but with conflicting findings. We studied retroversion in children with internal rotation contractures from neonatal brachial plexus palsy to clarify its effect on version and surgical planning. METHODS Bilateral shoulder and elbow magnetic resonance imaging scans of 21 children with neonatal brachial plexus palsy were retrospectively analyzed. Retroversion referenced to the transepicondylar line at the elbow was measured with respect to 2 different proximal reference axes, the longest diameter of an axial cut of the proximal part of the humerus (the skew axis) and the line perpendicular to the articular surface (the humeral center line). Glenoid version and glenohumeral morphology type (concentric glenoid, posterior-concentric glenoid, biconcave, or pseudoglenoid) were also determined. All geometric variables were assessed for correlation with patient age and the severity of the internal rotation contracture. RESULTS Retroversion on the involved side was decreased at 6° compared with 19° (p = 0.003), as measured between the skew axis and transepicondylar line. Retroversion referenced to the humeral center line was also decreased at -2° (anteversion) compared with 20° (p < 0.001). Patient age was inversely correlated with retroversion, but was only significant for the skew axis (r = -0.497, p = 0.022), decreasing in linear regression by 2.4° per year (p = 0.038). Humeral retroversion did not correlate with the severity of the internal rotation contracture, glenoid version, or glenoid morphology type. CONCLUSIONS Humeral retroversion is likely to be less on the affected side in children with internal rotation contractures from upper trunk neonatal brachial plexus palsy and merits consideration in surgical planning. LEVEL OF EVIDENCE Prognostic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Abstract
PURPOSE The clinicopathologic significance of mismatch repair (MMR) defects in endometrioid endometrial cancer (EEC) has not been definitively established. We undertook tumor typing to classify MMR defects to determine if MMR status is prognostic or predictive. METHODS Primary EECs from NRG/GOG0210 patients were assessed for microsatellite instability (MSI), MLH1 methylation, and MMR protein expression. Each tumor was assigned to one of four MMR classes: normal, epigenetic defect, probable mutation (MMR defect not attributable to MLH1 methylation), or MSI-low. The relationships between MMR classes and clinicopathologic variables were assessed using contingency table tests and Cox proportional hazard models. RESULTS A total of 1,024 tumors were assigned to MMR classes. Epigenetic and probable mutations in MMR were significantly associated with higher grade and more frequent lymphovascular space invasion. Epigenetic defects were more common in patients with higher International Federation of Gynecology and Obstetrics stage. Overall, there were no differences in outcomes. Progression-free survival was, however, worse for women whose tumors had epigenetic MMR defects compared with the MMR normal group (hazard ratio, 1.37; P < .05; 95% CI, 1.00 to 1.86). An exploratory analysis of interaction between MMR status and adjuvant therapy showed a trend toward improved progression-free survival for probable MMR mutation cases. CONCLUSION MMR defects in EECs are associated with a number of well-established poor prognostic indicators. Women with tumors that had MMR defects were likely to have higher-grade cancers and more frequent lymphovascular space invasion. Surprisingly, outcomes in these patients were similar to patients with MMR normal tumors, suggesting that MMR defects may counteract the effects of negative prognostic factors. Altered immune surveillance of MMR-deficient tumors, and other host/tumor interactions, is likely to determine outcomes for patients with MMR-deficient tumors.

Abstract
The ability to capture, enrich, and propagate circulating cancer cells/circulating tumor cells (CTCs) for downstream analyses such as ex vivo drug-sensitivity testing of short-term cultures of CTCs, single cell sorting of CTCs by fluorescence activated cell sorting (FACS), animal injection tumor and/or metastasis formation studies, next generation sequencing (NGS), gene expression profiling, gene copy number determination, and epigenomic analyses is of high priority and of immense importance to both the basic research and translational/clinical research communities. Vitatex Inc.'s functional cell separation technology, constructed as Vita-Assay™ (AG6W, AN6W, AR6W) culture plates, is based on the preferential adhesion of invasive rare blood cells of tissue origin to a tissue or tumor microenvironment mimic-the so-called cell adhesion matrix (CAM), which has a demonstrated ability to enrich viable CTCs from blood up to one-million fold.The CAM-scaffold allows for the functional capture and identification of invasive CTCs (iCTCs) including invasive tumor progenitor (TP) cells from cancer-patients' blood. CAM-captured CTCs are capable of ingesting the CAM (CAM+) itself. Green and red fluorescent versions of Vita-Assay™ (AG6W and AR6W) allow for direct visualization of CAM-uptake by cancer cells. Vita-Assay™ CAM-enrichment has allowed for sensitive multiplex flow cytometric and microscopic detection of iCTCs from patients with cancers of the breast, ovary, prostate, pancreas, colorectum, and lung; it has also been successfully utilized for ex vivo drug-sensitivity testing of ovarian-cancer patient CTCs. The CAM enrichment method is equally suitable for the separation of iCTCs and TP cells in ascites and pleural fluid.

Abstract
PURPOSE The best screening practice for Lynch syndrome (LS) in endometrial cancer (EC) remains unknown. We sought to determine whether tumor microsatellite instability (MSI) typing along with immunohistochemistry (IHC) and MLH1 methylation analysis can help identify women with LS. PATIENTS AND METHODS ECs from GOG210 patients were assessed for MSI, MLH1 methylation, and mismatch repair (MMR) protein expression. Each tumor was classified as having normal MMR, defective MMR associated with MLH1 methylation, or probable MMR mutation (ie, defective MMR but no methylation). Cancer family history and demographic and clinical features were compared for the three groups. Lynch mutation testing was performed for a subset of women. RESULTS Analysis of 1,002 ECs suggested possible MMR mutation in 11.8% of tumors. The number of patients with a family history suggestive of LS was highest among women whose tumors were classified as probable MMR mutation (P = .001). Lynch mutations were identified in 41% of patient cases classified as probable mutation (21 of 51 tested). One of the MSH6 Lynch mutations was identified in a patient whose tumor had intact MSH6 expression. Age at diagnosis was younger for mutation carriers than noncarriers (54.3 v 62.3 years; P < .01), with five carriers diagnosed at age > 60 years. CONCLUSION Combined MSI, methylation, and IHC analysis may prove useful in Lynch screening in EC. Twenty-four percent of mutation carriers presented with ECs at age > 60 years, and one carrier had an MSI-positive tumor with no IHC defect. Restricting Lynch testing to women diagnosed at age < 60 years or to women with IHC defects could result in missing a substantial fraction of genetic disease.

Abstract
Abstract
Purpose:
Cancer antigen 125 (CA125) is recognized as the leading biomarker in monitoring Epithelial Ovarian Cancer (EOC). More recently, invasive circulating tumor cells (iCTCs) have been introduced as a biomarker for metastatic potential. The goal of this research is to compare this biomarker with CA125 to determine the response to surgery and chemotherapy.
Experimental Design:
We compared clinical parameters with serial assays for iCTCs and CA125 in 129 fresh blood and 169 serum samples, respectively, from 31 patients who were receiving surgery and chemotherapy. iCTCs were capable of ingesting matrices (Cell Adhesion Matrix CAM+) and identified using positive tumor markers, Epi (EPCAM and CA125 or seprase and CD44), and negative selection markers, which exclude Epi-positive hematopoietic lineage (HL) cells, and enumerated by flow cytometry. iCTCs and CA125 levels were measured at time point less than 3-days apart.
Results:
A significant correlation was identified between changes in iCTC counts and CA125 levels (r=0.67, P<0.001) in the 83 samples collected prior to and after surgery and therapy. CA125 levels, but not iCTCs, were significantly reduced after surgery. During therapy, a significantly stronger concordance with clinical status was noted for decreasing values (specificity, 93.8% CA128; 90.6% iCTCs) compared with increasing values (sensitivity, 61.3% CA125; 83.9% iCTCs). Notably, increases in iCTCs, not CA125, were associated with increased risks for progressive disease (P<0.001). In the 8 patients who had >4 serial samples during therapy, changes in iCTC counts provided earlier measure of therapy response than CA125.
Conclusion:
This analysis showed that iCTC assay compared favorably with CA125 to monitor the response of chemotherapy in EOC patients, whereas changes of CA125 correlated better with reduced tumor burden after surgery.

Abstract
Objectives: Explore hypopharyngeal exposure to abnormally high or low pH during surgery performed under general endotracheal tube anesthesia and to compare results to published normative 24-hour data. Methods: Twenty volunteers for this prospective cohort study were recruited from June through September 2013. A wireless Dx-pH monitoring system was used during surgery. A drop from baseline to pH <5.5 was defined as a hypopharyngeal event, with thresholds pH 4.0, 4.5, and 5.0 also examined. Results were compared with supine events published by Chheda et al in 2009. Results: The number and duration of hypopharyngeal events <15 minutes with pH below 4.0, 4.5, 5.0 and percentage of surgery time in hypopharyngeal events (from a pH = 5.5 to return to baseline) were similar to comparative data. However, including all duration events (> ≤ 15 minutes), the number and duration of events at all thresholds and the percentage of surgery time in hypopharyngeal events were consistently higher than comparative data. Most analyses with the potential predictive/confounding variables (ie, body mass index, Reflux Symptom Index, Voice Handicap Index-10) yielded nonsignificant results. Conclusions: Extended pharyngeal exposure to moderately reduced pH levels (greater than sleeping or resting in a supine position) were documented. Approximately 20% of surgical patients may experience extensive exposure to pH <5.5 (over 1 hour, >30% of surgery time) and an additional 20% may experience moderate exposure to pH <5.5 (5-20 minutes and/or 4% to 10% of surgery time). Additional studies are needed to predict which patients might be at elevated risk for this exposure as well as the impact of this exposure on clinical outcomes.

Abstract
BACKGROUND Shoulder ROM and function of the shoulder are difficult to evaluate in young children. There has been no determination of the age at which children can comply with the current assessment tools in use, but doing so would be important, because it gives us more accurate insight into the development and assessment of shoulder functional ROM in young children. QUESTIONS/PURPOSES We (1) determined whether age would limit the use of two different observational scales used to assess shoulder ROM and function in young children (the Mallet scale and the ABC Loops protocol); and (2) compared the two scales in terms of intra- and interobserver reliabilities. METHODS Sixty-five able-bodied children (32 boys, 33 girls; mean age, 3.9 years; range, 0.5-7.0 years) were recruited from local preschools and evaluated using the Mallet scale and ABC Loops protocol. Children were assessed on their ability to complete the examinations and time to completion for each measurement protocol. Intra- and interobserver reliability was tested by percentage agreement. Forty-eight children (mean age, 4.4 years; SD, 1.3 years) were able to complete the Mallet and ABC Loops measurement protocols; 17 children (mean age, 2.3 years; SD, 1.1 years) failed to complete either test. RESULTS Younger children had more difficulty completing the examinations; there was a strong negative correlation between age and failure: probability of failure increased with decreasing age (Pearson r = -0.601, p < 0.001). Children who were able to complete one test were able to complete the other. Interobserver and intraobserver agreement was very high for both scales (in excess of 95% for all comparisons), and with the numbers available, there were no differences between the scales. CONCLUSIONS The Mallet scale and ABC Loops protocol have high reliability metrics in children younger than 6 years, but very young children (those younger than 3 years) generally will not be able to complete the examinations. The ABC Loops test took longer to perform than the Mallet scale but may more comprehensively evaluate a child's functional capabilities. We therefore state that both assessment tools can be reliably used in children older than 3 years; we believe the ABC Loops gives a more accurate assessment of shoulder ROM.

Abstract
BACKGROUND Little is known regarding the morphology of the proximal humerus in growing children. This study reports bilateral magnetic resonance imaging measurements in children with internal rotation contractures from birth palsy, hypothesizing that dysplasia alters normal humeral sphericity and symmetry. METHODS We studied 25 children with unilateral internal rotation contractures (mean age, 3.7 years) for humeral shape by bilateral magnetic resonance imaging studies at the mid-glenoid level. Local radii of curvature were compared for symmetry and orientation. RESULTS Neither side showed uniform radii (sphericity), but normal humeri showed symmetry lost in dysplasia. Internal rotation contractures were correlated with flattening of the anterior humeral head (P = .0002). All heads were flatter in the region of articular contact. The skew axis (the largest cross-sectional diameter of the proximal humerus) was collinear with the articular surface centerline in normal humeri, an alignment often lost with dysplasia, resulting in a skew axis angle. The severity of glenoid deformity correlated with progressive posterior displacement of the humeral head center (P < .0003). CONCLUSION The normal humeral articular surface in the young child is not spherical and is flatter in the middle than at the periphery but is symmetric about its central axis. Internal rotation contractures result in loss of this symmetry with characteristic flattening of the anterior humeral head and development of a skew axis angle. CLINICAL RELEVANCE Posterior displacement of the humeral head center of rotation beyond 50% of the calculated head radius warrants vigilance and possibly surgical intervention because there is a high likelihood for development of a pseudoglenoid.

Abstract
Abstract
Purpose: Circulating tumor cells (CTCs) might function as prognostic markers for monitoring and assessing therapy efficacy ex vivo. This study aimed to measure overall population of CTCs based on expression of epithelial lineage (Epi) markers and the subpopulation of CTCs with the invasive phenotype (iCTCs) in preoperative patients for prognosis of advanced Epithelial Ovarian Cancer (EOC).
Experimental Design: CTCs and iCTCs enriched by the Cell Adhesion Matrix (CAM)-coated devices from 122 preoperative patients were identified as Epi+ nucleic acid (NA)+ hematopoietic lineage (HL)- cells and CAM uptake (CAM+) Epi+ NA+ HL- cells, respectively. CTCs and iCTCs were enumerated using multiplex flow cytometry, validated by microscopy, and correlated with overall survival (OS) and progression-free survival (PFS).
Results: iCTCs were detected in 0/39 (0%) benign patients, 5/11 (45.5%) Stage I, 2/4 (50%) Stage II, 41/43 (95.3%) Stage III and 16/16 (100%) stage IV patients (P-value <0.001). However, healthy (n=48) and benign women had noticeable CTCs (mean=10 and 3 CTCs/1.0-mL blood, respectively), and large variation (IQR=24.5 and 30 CTCs/1.0-mL blood, respectively), although CTCs were significantly different across different stage groups. Kaplan-Meier estimates of OS at 5 years in the iCTC positive and negative groups were 15.4% (95% CI, 7.2% to 26.3%) and 94% (95% CI, 82.5% to 98%), respectively. The PFS in the iCTC positive group was also significantly lower than that in the negative group (P-value <0.001). In multivariable Cox models, iCTCs were independently predictive of OS (P-value <0.001) and provided predictive power for disease recurrence independent of diagnostic disease stages, age, debulking status and platinum sensitivity.
Conclusion: CTCs show the expression of heterogeneous epithelial antigens with potential biologic relevance. Co-expression of epithelial antigens and invasiveness of iCTCs in preoperative patients provides prognosis of advanced EOC that could help tailor appropriate therapy.

Abstract
PURPOSE The primary objective was to establish noninferiority of laparoscopy compared with laparotomy for recurrence after surgical staging of uterine cancer. PATIENTS AND METHODS Patients with clinical stages I to IIA disease were randomly allocated (two to one) to laparoscopy (n = 1,696) versus laparotomy (n = 920) for hysterectomy, salpingo-oophorectomy, pelvic cytology, and pelvic and para-aortic lymphadenectomy. The primary study end point was noninferiority of recurrence-free interval defined as no more than a 40% increase in the risk of recurrence with laparoscopy compared with laparotomy. RESULTS With a median follow-up time of 59 months for 2,181 patients still alive, there were 309 recurrences (210 laparoscopy; 99 laparotomy) and 350 deaths (229 laparoscopy; 121 laparotomy). The estimated hazard ratio for laparoscopy relative to laparotomy was 1.14 (90% lower bound, 0.92; 95% upper bound, 1.46), falling short of the protocol-specified definition of noninferiority. However, the actual recurrence rates were substantially lower than anticipated, resulting in an estimated 3-year recurrence rate of 11.4% with laparoscopy and 10.2% with laparotomy, or a difference of 1.14% (90% lower bound, -1.28; 95% upper bound, 4.0). The estimated 5-year overall survival was almost identical in both arms at 89.8%. CONCLUSION This study previously reported that laparoscopic surgical management of uterine cancer is superior for short-term safety and length-of-stay end points. The potential for increased risk of cancer recurrence with laparoscopy versus laparotomy was quantified and found to be small, providing accurate information for decision making for women with uterine cancer.

Abstract
PURPOSE To compare progression-free survival (PFS), overall survival (OS) and toxicities of thalidomide versus tamoxifen and to evaluate serum vascular endothelial growth factor (VEGF) in biochemical-recurrent epithelial ovarian cancer, primary peritoneal cancer or fallopian tube carcinoma (EOC/PPC/FTC). METHODS Biochemical recurrence was defined as a rising CA-125 exceeding twice the upper limit of normal without evidence of disease as defined by RECIST 1.0 criteria. Women with FIGO stages III and IV, histologically confirmed EOC/PPC/FTC who were free of disease following first-line chemotherapy were randomized to oral thalidomide 200mg daily with escalation to a maximum of 400 mg or tamoxifen 20mg orally twice daily for up to 1 year, progression or adverse effect prohibited further treatment. VEGF was quantified by ELISA in pre and post-treatment serum. RESULTS Of the 139 women randomized, 138 were eligible. Interim analysis showed that thalidomide did not reduce the recurrence rate relative to tamoxifen, and the trial was closed. Thalidomide versus tamoxifen was associated with a similar risk of progression (HR = 1.31, 95% confidence interval [CI] = 0.93-1.85), an increased risk of death (HR = 1.76, 95% CI = 1.16-2.68) and more grades 3 and 4 toxicities (55% versus 3%). The most common grades 3 and 4 toxicities were constitutional (12%), somnolence (12%), pulmonary (9%), venous thromboembolism (VTE) (6%) and peripheral neurologic (6%) for thalidomide, with VTE (1.4%) and gastrointestinal (1.4%) for tamoxifen. Serum VEGF was not associated with clinical characteristics, treatment, PFS or OS. CONCLUSION Thalidomide was not more effective than tamoxifen in delaying recurrence or death but was more toxic. VEGF was not prognostic in this cohort.

Abstract
PURPOSE The objective was to compare laparoscopy versus laparotomy for comprehensive surgical staging of uterine cancer. PATIENTS AND METHODS Patients with clinical stage I to IIA uterine cancer were randomly assigned to laparoscopy (n = 1,696) or open laparotomy (n = 920), including hysterectomy, salpingo-oophorectomy, pelvic cytology, and pelvic and para-aortic lymphadenectomy. The main study end points were 6-week morbidity and mortality, hospital length of stay, conversion from laparoscopy to laparotomy, recurrence-free survival, site of recurrence, and patient-reported quality-of-life outcomes. RESULTS Laparoscopy was initiated in 1,682 patients and completed without conversion in 1,248 patients (74.2%). Conversion from laparoscopy to laparotomy was secondary to poor visibility in 246 patients (14.6%), metastatic cancer in 69 patients (4.1%), bleeding in 49 patients (2.9%), and other cause in 70 patients (4.2%). Laparoscopy had fewer moderate to severe postoperative adverse events than laparotomy (14% v 21%, respectively; P < .0001) but similar rates of intraoperative complications, despite having a significantly longer operative time (median, 204 v 130 minutes, respectively; P < .001). Hospitalization of more than 2 days was significantly lower in laparoscopy versus laparotomy patients (52% v 94%, respectively; P < .0001). Pelvic and para-aortic nodes were not removed in 8% of laparoscopy patients and 4% of laparotomy patients (P < .0001). No difference in overall detection of advanced stage (stage IIIA, IIIC, or IVB) was seen (17% of laparoscopy patients v 17% of laparotomy patients; P = .841). CONCLUSION Laparoscopic surgical staging for uterine cancer is feasible and safe in terms of short-term outcomes and results in fewer complications and shorter hospital stay. Follow-up of these patients will determine whether surgical technique impacts pattern of recurrence or disease-free survival.

Abstract
PURPOSE To estimate the antitumor activity of pemetrexed in patients with persistent or recurrent platinum-resistant epithelial ovarian or primary peritoneal cancer and to determine the nature and degree of toxicities. PATIENTS AND METHODS A phase II trial was conducted by the Gynecologic Oncology Group. Patients must have had cancer that had progressed on platinum-based primary chemotherapy or recurred within 6 months. Pemetrexed at a dose of 900 mg/m(2) was to be administered as an intravenous infusion over 10 minutes every 21 days. Dose delay and adjustment was permitted for toxicity. Treatment was continued until disease progression or unacceptable adverse effects. RESULTS From July 6, 2004, to August 23, 2006, 51 patients were entered. A total of 259 cycles (median, four; range one to 19 cycles) of pemetrexed were administered, with 40% of patients receiving six or more cycles. Overall, the treatment was well tolerated. More serious toxicities (grade 3 and 4) included neutropenia in 42%, leukopenia in 25%, anemia in 15%, and constitutional in 15% of patients. No treatment-related deaths were reported. One patient (2%) had a complete and nine patients (19%) had partial responses, with a median duration response of 8.4 months. Seventeen patients (35%) had stable disease for a median of 4.1 months. Eighteen patients (38%) had increasing disease. Three patients (6%) were not assessable. Median progression-free survival was 2.9 months, and overall survival was 11.4 months. CONCLUSION Pemetrexed has sufficient activity in the treatment of recurrent platinum-resistant ovarian cancer at the dose and schedule tested to warrant further investigation.

Abstract
OBJECTIVES The invasive growth of circulating tumor cells (CTCs) propagates cancer metastasis. The aims of this study were to evaluate the association of invasive CTCs, detected by a novel cell invasion assay, with disease stage, CA-125 level and patient survival. METHODS Peripheral blood samples from 71 patients undergoing evaluation for ovarian malignancy were assessed for the presence of invasive CTCs using a cell invasion assay that enriches and identifies tumor cells with a cell adhesion matrix (CAM). Invasive CTCs were identified as cells exhibiting CAM invasion (CAM+) and expressing standard epithelial markers (Epi+). RESULTS 43 (60.6%) patients had detectable CTCs: 0/5 benign patients, 1/10 (10%) early stage, 39/52 (73.1%) late stage and 3/4 (75%) unstaged patients (p-value <0.001). CTC counts ranged from 0-149 CTCs/ml with stage III/IV patients exhibiting significantly higher mean counts (41.3 CTCs/ml) than stage I/II patients (6.0 CTCs/ml) and benign patients (0 CTCs/ml, p-value=0.001). A positive correlation between CTC count and CA-125 level was observed (Spearman correlation coefficient r=0.309, p-value=0.035). Kaplan-Meier curves revealed a significant decrease in disease-free survival in patients with detectable CTCs (median survival 15.0 months vs. 35.0 months, log-rank p-value=0.042). Tumor grade and tumor histology did not influence CTC detection. CONCLUSIONS Invasive CTCs can be detected in a majority of epithelial ovarian cancer patients and may predict shorter disease-free survival. Furthermore, higher CTC counts may reflect later stage disease and higher CA-125 levels.

Abstract
The topoisomerase I agents are established as a therapy in recurrent ovarian cancer. Karenitecin, an analog of topotecan with solubility and pharmacologic advantages, was tested in a phase II trial in previously treated patients with recurrent or persistent ovarian cancer. The drug was administered intravenously over 1 h at a dose of 1.0 mg/m(2) daily for 5 days every 21 days. Patients were treated until disease progression, intolerable toxicity, or voluntary withdrawal. Response was evaluated according to modified RECIST criteria. Twenty-seven patients were entered into the study. One patient was inevaluable for not receiving any treatment. Of the 26 evaluable patients, there were two partial responses and one complete response for a total response rate of 12%. This response rate was insufficient to justify accrual to the second stage. The most common grade 3 or 4 toxicities were neutropenia (19%) and gastrointestinal (15%). Karenitecin is a well-tolerated topoisomerase compound but has minimal activity in extensively pretreated ovarian cancer with the dose-schedule employed.

Abstract
BACKGROUND/AIMS A phase II study was conducted to assess the activity and toxicity of weekly docetaxel in patients with advanced or recurrent cancer of the cervix. METHODS Eligible patients were required to have measurable disease with adequate performance status, bone marrow, renal and hepatic function. Patients were allowed to receive chemosensitization and not more than one prior chemotherapy regimen excluding taxanes. Docetaxel 35 mg/m2 was administered intravenously weekly for 3 weeks followed by 1 week off until disease progression or adverse effects prohibited further therapy. RESULTS Ten patients were entered into this study, all of who were evaluable for toxicity and response. A median of 2 cycles (range 2-6) were administered. The most frequent drug-related toxicities were anemia and fatigue. There were no objective responses. Three patients had stable disease up to 6 cycles. One patient died of exsanguination from a known vaginal metastasis after completing her second cycle. The median progression-free interval was 1.7 months (range 0.9-5.8) and overall survival was 6.9 months (1.6-23.7). CONCLUSIONS Docetaxel has limited activity in patients with recurrent cancer of the cervix at the dose and schedule tested.

Abstract
BACKGROUND/AIMS Stages III and IV ovarian and peritoneal cancer patients are commonly treated with combination chemotherapy after surgical debulking. This phase II trial investigated the use of pegylated liposomal doxorubicin as consolidation chemotherapy for these patients. METHODS Women with stage III or IV ovarian or primary peritoneal carcinoma demonstrating no clinical evidence of disease after primary therapy were eligible for enrollment. Patients received 4 cycles of 40 mg/m(2) IV of pegylated liposomal doxorubicin every 28 days. RESULTS Twelve patients were enrolled. There were 6 stage IIIC and 6 stage IV patients. Ten patients received 4 cycles. Two patients had dose limiting skin toxicity manifest as hand-foot syndrome and received only 3 cycles. Forty-six of a planned 48 cycles were administered. Median disease-free survival from registration is 10 months with a mean of 18 months. Median overall survival has not yet been reached. Four patients are disease-free, two have relapsed and six have died from disease progression. CONCLUSION Pegylated liposomal doxorubicin is a well-tolerated choice for consolidation chemotherapy in patients with ovarian or primary peritoneal carcinoma.

Abstract
BACKGROUND Internal rotation contractures due to external rotation weakness secondary to brachial plexus birth palsy frequently lead to glenohumeral deformity and impaired shoulder function. Our surgical approach to treat these contractures relies on arthroscopic release for young children (less than three years old) and combines arthroscopic release with latissimus dorsi transfer for older children. We report the results for the first thirty-three children followed for a minimum of two years after such treatment. METHODS Nineteen children with a mean age of 1.5 years (all younger than three years of age) underwent arthroscopic contracture release as the only primary procedure, and fourteen children with a mean age of 6.7 were also treated with a latissimus dorsi transfer. Passive external rotation with the arm at the side and passive and active elevation were measured for all patients preoperatively. Passive and active external rotation, internal rotation, and elevation were measured for all patients postoperatively. Magnetic resonance imaging was performed preoperatively and postoperatively to evaluate the status of the glenohumeral joint. RESULTS Preoperative passive external rotation averaged -2 degrees for the children who underwent arthroscopic contracture release only and -24 degrees for those who also were treated with a latissimus dorsi transfer. Arthroscopic release achieved a marked increase in passive external rotation and a centered position of the glenohumeral joint at the time of surgery in all but the oldest child in the series, who had severe deformity. The contracture recurred in four of the younger children who had an isolated release, and this was treated with a repeat arthroscopic release and a secondary latissimus dorsi transfer. None of the children who had a primary latissimus dorsi transfer had recurrence of the contracture. At the time of follow-up, the mean passive external rotation was increased by 67 degrees (p < 0.005) in the fifteen children with a successful arthroscopic release, 81 degrees (p < 0.005) in those treated with a primary latissimus dorsi transfer, and 78 degrees in the four patients who were treated with a late latissimus dorsi transfer because the isolated arthroscopic release failed. The mean active elevation increased 12 degrees , 3 degrees , and 10 degrees , respectively, in the three groups. Internal rotation was not measured consistently preoperatively, but when it had been it was found to have decreased substantially postoperatively. Magnetic resonance imaging performed prior to the surgery showed a pseudoglenoid deformity in eighteen of the children. At two years, magnetic resonance images were available for fifteen of those children, and twelve of the images showed marked remodeling of the deformity. CONCLUSIONS In children who are younger than three years of age, arthroscopic release effectively restores nearly normal passive external rotation and a centered glenohumeral joint at the time of surgery. In most of these children, external rotation strength is sufficient to maintain this range of motion and to improve glenoid development when preoperative deformity was present. The addition of a latissimus dorsi transfer in older children predictably results in similar improvements. Gains in active elevation are minimal. All children have a loss of internal rotation, which is moderate in most of them but is severe in some.

Abstract
Resurfacing arthroplasty of the glenohumeral joint has been established for several decades as a means to restore comfort and function of the shoulder for many afflictions that derange the normal anatomy. Rigorous study of shoulder anatomy in terms relevant to prosthetic geometry, however, did not begin until the 1990s. It has become apparent that normal anatomy is highly variable from individual to individual and that it is aligned somewhat differently than the early modular prosthetic devices. Multiple studies have shown that retroversion is markedly variable, not only between individuals but also between the left and right sides of the same individual, ranging from 0 degrees to 55 degrees . The inclination of the proximal humeral articular surface relative to the shaft (head shaft angle) is also variable, ranging from 30 degrees to 55 degrees. The center of rotation is variably offset in 3 dimensions. The radius of curvature ranges from 20 to 30 mm and is smaller in women than in men. The thickness of the articular surface, head height, is equally variable but shows a striking proportionality to the radius of curvature. The last decade has seen a proliferation of humeral implants aiming to serve a better understanding of shoulder anatomy and function. A modern understanding of shoulder anatomy and contemporary design features is paramount for surgeons performing shoulder arthroplasty. Head size selection is dependent on multiple factors, the most important of these, other than the patient's original head size, are the osteotomy performed by the surgeon and the inclination angle(s) of the prosthetic system. Systems with variable inclination angles instruct the surgeon to resect the humeral head along the anatomic neck as best possible and then provide either adjustable or variable prosthetic geometries to match the resultant inclination angle. Other prosthetic systems have a fixed inclination angle somewhere within the normal range and instruct the surgeon to make an osteotomy at this inclination, adjusting the fit with additional preparation of the canal and revising the osteotomy as necessary. Over the last decade, most systems have offered heads that are offset by 3 to 4 mm, allowing the surgeon to dial in the most suitable position for the head on the stem. Component design and surgical technique are inextricably intertwined. Most surgeons with experience using modern systems feel a greater sense of predictability in achieving their surgical goals when using these systems as compared with earlier ones. How these developments impact implant longevity will only be known with time and further follow-up.

Abstract
OBJECTIVE The Gynecologic Oncology Group (GOG) has studied a number of drugs to determine their activity in patients with previously treated squamous and nonsquamous cancer arising in the uterine cervix. A Phase II study with intravenous vinorelbine was initiated for this purpose in patients with Stage IVB, recurrent, or persistent nonsquamous carcinomas who had received one prior chemotherapy or were not eligible for other studies. METHODS Eligible patients had to have measurable disease, GOG performance status of 0-2 and adequate bone marrow, liver, and renal function. The treatment consisted of vinorelbine 30 mg/m(2) on days 1 and 8, repeated every 21 days. Tumor measurements and toxicities were recorded every treatment cycle. RESULTS Thirty patients were enrolled with 28 patients deemed eligible and evaluable. Only two confirmed partial responses (7.1%) were noted. Neutropenia was the most common toxicity with 9 of 28 (32%) experiencing either grade 3 or 4 changes. Anemia was severe in seven. Neuropathy was more than mild in three patients. Severe events, such as fatigue, hypertension, or pulmonary changes attributed to drug administration, occurred only in one or two instances. CONCLUSION With the dose schedule and assessment criteria employed, vinorelbine had only minimal activity in nonsquamous cancer of the cervix.

Abstract
Clinical experience with humeral implants has evolved over the past decade, along with a better understanding of shoulder anatomy and function. There is no question that surgeons are getting better at restoring normal anatomic relationships than in preceding decades. Whether or not this impacts implant longevity will only be known with time and further follow-up. Even over the short term, it is difficult to ascertain whether new prosthetic designs have improved patient function as well as has been implied by the related biomechanical studies. Most surgeons with experience using old and new systems realize a greater sense of predictability in achieving their surgical goals when using more modern implants. Concerns over the durability of prosthetic systems with multiple moving parts and hand-tightened locking mechanisms have almost been forgotten in shoulder arthroplasty, but time will also reveal their importance. New glenoid designs have been less exciting, the major problem being one of developing appropriate materials. Polyethylene does not behave like normal cartilage, and its wear is constant and unforgiving. Surgeons now better understand how to reconstruct the normal glenoid position and achieve more secure early fixation than in the past, but this does not promise long-term durability and freedom from complications.

Abstract
OBJECTIVE This multi-center phase II trial was conducted by the Gynecologic Oncology Group to evaluate the activity and toxicity of irofulven in patients with previously treated adenocarcinoma of the endometrium. METHODS Eligible patients had documented recurrent or persistent endometrial carcinoma after receiving definitive locoregional therapy, and were required to have measurable disease, performance status of 0-2, and adequate bone marrow, hepatic and renal functions prior to study entry. Patients were allowed one prior chemotherapy regimen. The initial dose of irofulven was 11 mg/m(2)/day for four days administered intravenously. Cycles were repeated every 28 days. Doses were escalated or reduced based on previous cycle toxicity. RESULTS Twenty-five patients were enrolled onto the trial. There was one (4%) confirmed complete response. Seven (28%) patients had stable disease, with a median duration of 10.4 (range: 4.4-21.6) months. Patients received a median of one (range: 1-5) cycle of protocol treatment. There were three early treatment-related deaths due to renal failure and severe electrolyte disturbances. Two patients experienced grade 4 hematologic adverse effects. CONCLUSION Irofulven administered at the dose and schedule used in this trial was minimally active and resulted in significant toxicity.

Abstract
This review summarizes contemporary concepts of abdominal surgical incision creation and closure. The Ovid computerized database was searched for articles published in English from 1996 to 2003 using keywords pertaining to the specific topic of interest (e.g., suture, drain, surgical technique, fascia). Human prospective, randomized trials; meta-analyses; and evidence-based-focused reviews were assessed and data abstracted. Several earlier and animal-based studies on specific issues were included. The data indicate that: (1) the direction of the incision should be based upon obtaining adequate exposure; (2) hair should either be left in place or clipped at the time of surgery; (3) a single dose of prophylactic antibiotics should be given 30 minutes prior to surgery; (4) using a "deep" scalpel is unnecessary; (5) a scalpel and electrocautery are comparable for deepening the incision; (6) minimal peritoneal lavage with non-antibiotic containing solutions is adequate; (7) the peritoneum should not be routinely closed; (8) the fascia should be loosely approximated by a continuous mass closure using a slowly absorbable, monofilament suture with the smallest possible caliber and a suture:wound length ratio of at least 4:1; (9) retention sutures, subcutaenous sutures and drains do not appear to reduce the risk of wound complications; and (10) the skin may be closed in a variety of methods, but a semiocclusive dressing should be applied. As scientific evidence accumulates to refute traditional dogma, management of the surgical patient has undergone substantial changes. Surgeons should now be able to create and close an abdominal wound based upon sound scientific principles rather than simply "doing what I always do."

Abstract
PURPOSE To evaluate, with intraoperative arthrography, joint morphology in children undergoing surgical treatment of residual paralysis of the shoulder resulting in brachial plexus birth palsy and to correlate the morphology with the degree of passive external rotation. MATERIALS AND METHODS In 64 children (age range, 7 months to 13 years 6 months), an orthopedic surgeon performed intraoperative arthrography and measured passive external rotation while the patient received a general anesthetic. The orthopedic surgeon and three radiologists reviewed arthrograms and in consensus classified glenohumeral joints in one of four categories: concentric, with the humeral head well centered on the glenoid fossa; flat, with flattening of the posterior glenoid; biconcave, with the humeral head in articulation with the posterior of two concavities, which were in the same plane; and pseudoglenoid, with the humeral head in articulation with the more posterior of two concavities, with retroversion and in a plane different from that of the anterior concavity. Kruskal-Wallis test was used to compare preoperative external rotation with four appearances of glenoid. RESULTS Twenty-one children had concentric glenohumeral joints; seven children, flat glenohumeral joints; 19 children, biconcave glenoid; and 17 children, pseudoglenoid. Median passive external rotation was -20 degrees for patients with pseudoglenoid, -10 degrees for those with flat or biconcave glenoids, and 0 degrees for those with concentric glenoids. Presence and type of glenoid deformity were significantly associated with severity of internal rotation contracture (P <.001). CONCLUSION Consistent patterns of glenohumeral joint deformity in brachial plexus birth palsy were identified and correlated with severity of internal rotation contracture.

Abstract
PURPOSE Internal rotation contractures are common in children with external rotation weakness secondary to brachial plexus birth palsy. Surgical release of the contracture, with or without latissimus dorsi transfer, is an established treatment through a variety of open methods. This article describes an arthroscopic method of contracture release in this patient population. TYPE OF STUDY New surgical technique. METHODS Forty-one children with contractures, ranging in age from 8 months to 12 years (mean, 3.5 years), underwent arthroscopic release of the shoulder with a 2.7-mm arthroscope used for visualization. The release consisted of a subscapularis tenotomy and release of the anterior capsular ligaments. Eighteen children underwent a subscapularis release as an isolated procedure. Twenty-three of the children also underwent latissimus dorsi transfer. RESULTS Arthroscopic release was successful in achieving at least 45 degrees of passive external rotation at surgery in all but one case. This case was in the oldest child, a 12-year-old with severe deformity, who needed an open release. No other complications were noted. Glenohumeral deformity was common. The primary contracted elements were the subscapularis and the anterior capsular ligaments. CONCLUSIONS Arthroscopic contracture release was effective in the restoration of passive external rotation in children with internal rotation contractures secondary to birth palsy.
