Abstract
PURPOSE Single-agent PD-1 blockade exhibits limited efficacy in epithelial ovarian cancer (EOC). We evaluated ipilimumab plus nivolumab compared with nivolumab alone in women with persistent or recurrent EOC. METHODS Eligibility criteria included measurable disease, 1-3 prior regimens, and platinum-free interval (PFI) < 12 months. Participants were randomly allocated to intravenous nivolumab (every 2 weeks) or induction with nivolumab plus ipilimumab for 4 doses (every 3 weeks), followed by every-2-week maintenance nivolumab for a maximum of 42 doses. The primary null hypothesis was equal probability of objective response within 6 months of random allocation in each arm. RESULTS One hundred patients were allocated to receive either nivolumab (n = 49), or nivolumab plus ipilimumab (n = 51), with PFI of < 6 months in 62%. Six (12.2%) responses occurred within 6 months in the nivolumab group and 16 (31.4%) in the nivolumab plus ipilimumab group (odds ratio, 3.28; 85% CI, 1.54 to infinity; P = .034). The median progression-free survival (PFS) was 2 and 3.9 months in the nivolumab and nivolumab plus ipilimumab groups, respectively, with a PFI-stratified hazard ratio of 0.53 (95% CI, 0.34 to 0.82); the respective hazard ratio for death was 0.79 (95% CI, 0.44 to 1.42). Grade ≥ 3 related adverse events occurred in 33% of patients in the nivolumab group and 49% in the combination group, with no treatment-related deaths. PD-L1 expression was not significantly associated with response in either treatment group. CONCLUSION Compared with nivolumab alone, the combination of nivolumab and ipilimumab in EOC resulted in superior response rate and longer, albeit limited, PFS, with toxicity of the combination regimen comparable to prior reports. Additional combination studies to enhance durability of the dual regimen are warranted.

Abstract
11583 Background: This was a randomized control trial to estimate the effect of an interventional video on improving palliative care knowledge and acceptability of outpatient services in gynecologic oncology patients. Methods: Women receiving active treatment for gynecologic malignancy (persistent or progressive disease despite primary treatment) were recruited at an academic tertiary care center from 2/2018 to 1/2019 and randomized to: palliative care educational video or non-directive cancer center informational video (control). The primary outcome was desire for referral to palliative care. Function and knowledge were assessed using the Functional Assessment of Cancer Therapy (FACT-G) and the Palliative Care Knowledge Scales. Data analyses were performed using t-tests, Wilcoxon rank sum or Fisher’s exact tests with significance level of α=0.05. Results: 111 women were enrolled. Demographic characteristics were equally distributed between groups (mean age 63.4 vs 65.4 years; 78% vs 82% Caucasian, 58% vs 68% stage III, 71% vs 64% ovarian cancer, 65% vs 72% platinum-sensitive). There was no statistical difference in knowledge scores or in desire for referral to palliative care (29% vs 27%; p=0.79). Secondary analysis showed a statistically significant increase in utilization of palliative care services compared to historic institutional data (8.8% to 29.7%; p=<0.001). Further, those that desired referral had significantly worse FACT-G scores at time of referral choice (table). Conclusions: Use of a palliative care educational video did not increase knowledge or acceptability of palliative care services within this RCT. However, the rate of patients seeking palliative care referral tripled compared to historic rates. Further studies should investigate whether discussion regarding palliative care services alone may increase desire for referral, and if use of Fact-G scores may identify patients in greatest need of services.

Abstract
Background Acute febrile illness is a frequent cause of hospitalization in the tropics and often presents with respiratory symptoms, even when caused by nonrespiratory pathogens. Previously, host-based gene expression signatures accurately identified acute respiratory infections as being bacterial or viral in a U.S. cohort. We determined signature performance in a Sri Lankan cohort with acute febrile respiratory illness (AFRI). Methods We enrolled patients with AFRI in Sri Lanka from July 2012 to May 2013 and collected nasopharygeal swabs, acute/ convalescent sera, and blood in PAXgene RNA tubes. Bacterial (Orientia tsutsugamushi, Leptospira spp.) and viral (influenza A/B, dengue) infections were confirmed using polymerase chain reaction, virus isolation, enzyme immunoassay, and/or microscopic agglutination testing. We extracted total RNA and performed host RNA sequencing (Illumina). We aligned reads to hg38 reference genome using Bowtie2, quantified at isoform level using Express version 1.5.1, and normalized using trimmed-mean normalization. The original model estimated three classes and separate signatures predicted bacterial infections, viral infections, and non-infectious illnesses. Regularized regression was used to predict bacterial and viral infections based on prior signatures. Accuracy was estimated using leave-one-out cross-validation. Results Among 43 patients with viral infections (14 dengue, 29 influenza) and 16 patients with bacterial infections (six Leptospira spp., 10 O. tsutsumagushi), median age was 37 years (IQR 23–51) and 49% were male. Of five respiratory symptoms (cough, sore throat, rhinitis/ congestion, shortness of breath, and pain with breathing), median (IQR) number of symptoms was 2 (1–2) for influenza, 2 (1–2) for dengue, 2 (2–3) for Leptospira spp., and 1.5 (1–2) for O. tsutsumagushi. We observed high predictive accuracy in discriminating bacterial and viral infections: AUROC 0.91 for the bacterial and AUROC 0.81 for the viral model. At enrollment, 65% of viral and 50% of bacterial AFRI patients received antibiotics. Conclusion Host gene expression classifiers performed well in a Sri Lankan population with AFRI, even with nonrespiratory pathogens that may not be readily identified. Host-based diagnostics may play a critical role in improving diagnostic ability and antibiotic use globally. Disclosures E. L. Tsalik, Host Response, Inc.: Founder, Equity. G. S.

Abstract
OBJECTIVES We sought to determine a baseline and five-year follow up sexual function score in women undergoing hysterectomy for endometrial cancer. METHODS A cross-section of endometrial cancer patients receiving care from 2006 to 2010 was identified. Patients were surveyed during academic year 2011 using the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ). Respondents were re-surveyed in 2016. The PISQ was also administered at a single time point to a control group of urogynecology patients. Statistical analyses were conducted using STATA software, version 13.1. RESULTS 129 endometrial cancer and 63 matched urogynecology patients responded to an initial survey and sufficiently answered the PISQ. There was no statistical difference in BMI, race, diabetes, or smoking history between groups. In 2011, 62.5% of endometrial cancer patients versus 72.6% of urogynecology patients reported sexual activity (p = 0.166). Median PISQ score for these groups was 33 [IQR 29-38] and 32 [IQR 28-37] respectively (p = 0.472). Twenty-nine (22%) endometrial cancer patients sufficiently answered the initial and 5-year follow up PISQ to be included in follow up analysis. Median PISQ score at five years was not significantly different from baseline: 31 [IQR 27-39] versus 33 [IQR 31-38] (p = 0.299). With multivariable modeling, no demographic or clinical characteristics of endometrial cancer patients were independently associated with sexual function (p = NS). CONCLUSIONS Sexual function for endometrial cancer patients was not significantly different from women treated for benign disease. Sexual function also remained stable for endometrial cancer patients regardless of time from initial treatment. Further prospective studies are needed to better characterize sexual function in endometrial cancer survivors.

Abstract
PURPOSE/OBJECTIVES To establish the feasibility and acceptability of completing a higher dose of the planned physical activity volume among women with ovarian cancer, including those undergoing active treatment.
. DESIGN A pre-/post-test exercise intervention. All participants were asked to complete 225 minutes per week of physical activity for 26 weeks. Multiple supports were provided, including exercise DVDs, self-reported logs, and an objective physical activity tracker (Fitbit®).
. SETTING Home-based exercise intervention with in-person training and telephone follow-ups.
. SAMPLE 10 women with ovarian cancer who were treated within Penn Medicine in Philadelphia, Pennsylvania.
. METHODS Home-based, in-person exercise counseling was provided by an exercise trainer weekly for the first six weeks and then monthly for a total of 26 weeks. Weekly follow-up telephone calls were used to assess exercise adherence and barriers to completing exercise, review symptom changes, and provide behavioral support.
. MAIN RESEARCH VARIABLES Feasibility and acceptability.
. FINDINGS Eight participants completed the study and achieved at least 80% of the prescribed exercise dose. Five participants were undergoing chemotherapy simultaneously. Participants experienced no adverse events during the 26-week intervention. Compared to baseline, average steps increased by 1,593 per day and moderate-intensity physical activity increased by 15 minutes per day.
. CONCLUSIONS A 225-minutes-per-week exercise program is feasible and acceptable in a population of patients with ovarian cancer. Participants significantly improved their physical activity during the 26-week intervention.
. IMPLICATIONS FOR NURSING The findings suggest that nursing professionals could recommend that women with ovarian cancer exercise 225 minutes per week regardless of cancer and/or treatment trajectory. For those experiencing aches and pains, behavioral supports and suggestions of a lower exercise dose are needed to maintain physical activity.

Abstract
BACKGROUND Women with gynecologic cancer are at higher risk of venous thromboembolism (VTE) due to malignancy, pelvic surgery, increased age, and frequently comorbidities. The rate of VTE among different gynecologic cancers and relative to benign gynecologic surgeries has not been reported in a nationally representative cohort. METHODS Using the American College of Surgeons National Surgical Quality Improvement Program database, gynecologic surgeries were identified retrospectively from 2006 to 2012. Clinical characteristics, surgical procedures, and 30-day postoperative complications were abstracted. Multivariable logistic regression models were performed. RESULTS Of all gynecologic surgeries (n = 104,368), 11,427 were performed for malignancy: 2.7% (n = 2800) for ovarian cancer, 6.8% (n = 7114) for uterine cancer, 1.0% (n = 1026) for cervical cancer, and 0.5%(n = 487) for vulvar cancer. 202 (1.8%) patients experienced a VTE. Ovarian cancer had a deep venous thrombosis and pulmonary embolism rates of 1.6% and 1.5% compared with uterine cancer, 0.8% and 0.8%, respectively. Ovarian cancer patients were 1.8 (95% confidence interval [CI], 1.19-2.65) times more likely to have a deep venous thrombosis and 1.7 (95% CI, 1.11-2.51) times more likely to have a pulmonary embolism than patients with uterine cancer. Compared with all gynecologic cancer surgeries, ovarian cancer patients were 1.5 times more likely to have a VTE (95% CI, 1.10-2.16). Patients undergoing minimally invasive surgery were 64% less likely to have a VTE regardless of malignancy site; however, if they had disseminated disease, they remained at higher risk of VTE (odds ratio, 5.96; P = 0.027). CONCLUSIONS Of gynecologic cancer surgeries, ovarian cancer patients had the highest rate of VTE. Venous thromboembolism rates were lower in those who had minimally invasive surgery but remained higher in those with disseminated disease.

Abstract
Abstract
Background: The management of benign intraductal papillomas on core biopsy is controversial. The aim of this study was to determine factors that predict under-evaluation of atypical lesion or malignancy in patients diagnosed with benign papilloma at ultrasound-guided core needle biopsy (CNB), and to develop a prediction algorithm for scoring the possibility of a diagnosis upgrade to atypical lesion or malignancy based on clinical, radiological and pathological factors.
Methods: The study enrolled patients diagnosed with benign papilloma at ultrasound-guided CNB who subsequently underwent surgical excision of the lesion. Multivariate analysis was used to identify relevant clinical, radiological and pathological factors that may predict malignancy.
Results: A total of 520 CNBs led to a diagnosis of benign papilloma (including benign and atypical papillary lesion), of which 452 CNBs were benign papilloma without atypia. Of the 250 lesions in 234 women were underwent subsequent surgical excision, 44 (17.6%) were diagnosed with atypia or malignancy. Multivariate analysis revealed that bloody nipple discharge, size on imaging ≥15 mm, BIRADS≥4b, peripheral location, and a palpable lesion were independent predictors of atypical lesion or malignancy. A scoring system was developed based on logistic regression models and beta coefficients for each variable. The area under the ROC curve was 0.830 (95% CI: 0.665-0.996), and the negative predictive value was 100% for a score ≤4.
Conclusions: A scoring system to predict malignancy in patients diagnosed with benign papilloma at CNB was developed based on five factors: bloody nipple discharge, size on imaging ≥15 mm, BIRADS≥4b, peripheral location, and a palpable lesion. This system was able to identify a subset of patients with lesions likely to be benign, indicating that imaging follow-up rather than surgical excision may be appropriate.

Abstract
A rare benign condition of uncertain etiology and pathogenesis, Synovial Chondromatosis (SC) is most often seen intraarticularly in adults but only a handful of cases have been reported extraarticularly in children. Symptoms and physical signs consist of pain, swelling, and osteoarthritic changes related to a mass effect. Here we discuss the case of a 9-year-old boy with documented SC of the knee and critically review the Epidemiology, Clinical Presentation, Gross Anatomy and Microscopic Histopathologic Features as well as the role of Imaging Studies in Diagnosis. In addition, this paper reviews Current Pathogenetic Concepts including the infrequent but distinct possibility of malignant transformation.

Abstract
The immunosuppressive effects of Sophorae radix (SR) make this plant an attractive agent for the treatment of autoimmune diseases. The effect of SR on systemic lupus erythematosus (SLE) in the New Zealand Black/White F1 (NZB/w F1) mouse model system was investigated. Three-month-old NZB/w F1 mice were separated into two groups: one treated with SR (1% SR solution by oral administration, daily for 15 weeks) and one with water as a control. Experimental parameters include proteinuria, anti-dsDNA antibody titers, T-cell response and renal histopathological analysis. Results in the SR-treated group showed a significant reduction in proteinuria and anti-dsDNA antibodies either in serum or in glomerular capillaries, along with significant recovery from renal glomerular damage. The lymphocyte population was significantly increased in the SR-treated mice compared with the control group. In the T helper (Th)1/Th2 cytokine secretion profile, interferon-γ in splenocyte culture was significantly reduced in the SR-treated mice, while interleukin-4 secretion was not altered. These results strongly suggest SR therapy corrects the deviated Th1/Th2 balance, thereby alleviating SLE-like symptoms in the NZB/w F1 mice. Therefore, SR may be useful in the clinical treatment of SLE. Lupus (2007) 16, 335—341.

Race-based disparities in loss of functional independence after hysterectomy for uterine cancer. Support Care Cancer 2016; 24:3573-80. [PMID: 27025595 DOI: 10.1007/s00520-016-3185-3] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2015] [Accepted: 03/21/2016] [Indexed: 12/27/2022]
Abstract
PURPOSE Racial disparities in uterine cancer-related outcomes have been reported. The goal of this study was to determine if race, pre-operative body mass index (BMI), and medical comorbidities are predictors of loss of functional independence after hysterectomy for uterine cancer. METHODS Loss of independence was defined as a change from pre-operative functional independence, to a post-operative requirement of discharge to a post-care facility, or death within the first 30 days following uterine cancer surgery. Demographic factors, comorbidities, BMI, intra-operative and post-operative outcomes, and discharge status were abstracted from the 2011 and 2012 American College of Surgeons National Surgical Quality Improvement Program (NSQIP). Statistical analyses included multivariable logistic regression and Wald tests for interaction. RESULTS A total of 4005 patients had uterine cancer and were functionally independent pre-operatively. After adjusting for clinical features and comorbidities, Black women were not significantly more likely to lose functional independence than non-Black women. However, a significant interaction (OR = 1.17, p < 0.001) was found between race and BMI for loss of functional independence. Interaction plots revealed worsening functional outcomes for Black women with BMI >40 but not in non-Blacks. CONCLUSIONS The interaction suggests a 17 % increased odds of losing independence for each unit of BMI difference for Black uterine cancer patients, or 170 % increased odds of losing independence for a 10-point increase in BMI, given a linear association. To reduce the likelihood of losing post-operative functional independence, Black, high-BMI patients with or at risk for uterine cancer may especially benefit from weight loss or interventions to optimize physical function.

The use of novel technology-based weight loss interventions for obese women with endometrial hyperplasia and cancer. Gynecol Oncol 2016; 140:239-44. [PMID: 26644265 PMCID: PMC6771417 DOI: 10.1016/j.ygyno.2015.11.033] [Citation(s) in RCA: 30] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2015] [Revised: 11/08/2015] [Accepted: 11/27/2015] [Indexed: 01/16/2023]
Abstract
OBJECTIVE Obesity significantly increases the risk of the development of both endometrial hyperplasia and cancer. Our objective was to assess the feasibility of two technology-based weight loss interventions in this patient population. METHODS Women with obesity (BMI≥30kg/m(2)) and endometrial hyperplasia or Type I endometrial cancer were randomized 1:1 to a technology-based 6month lifestyle intervention via either telemedicine or text messaging. The telemedicine arm received weekly phone calls, with weights tracked online using Withings© Wi-Fi scales. The text arm received 3-5 personalized messages daily via Text4Diet™. Participants maintained a 1200-1800calorie/day diet, self-monitored food intake and received exercise goals. Biomarkers (IGFBP-1, adiponectin, VEGF, IL1-beta, IL2, IL6, and IL7) were assessed pre- and post-treatment. RESULTS Twenty women were randomized (Telemedicine: n=10, Text4Diet: n=10), and 90% lost weight. Many were early stage (70%) and grade (43.8%) disease with a median age of 60.5years. We observed a statistically greater weight loss in the Telemedicine arm [median loss: 9.7kg (range: 1.6-22.9kg)] versus 3.9kg (range: 0.3-11.4kg) in the Text4Diet arm (p=0.0231). Similarly, percent weight loss was greater in the Telemedicine (7.6%) as compared to the Text4Diet arm (4.1%, p=0.014). Mean serum levels of IL-2 were significantly (27.15pg/mL vs. 5.18pg/mL, p=0.0495) lower at intervention end as compared to baseline. CONCLUSIONS A technology-based weight loss intervention is feasible in women with Type I endometrial cancer/hyperplasia. Both interventions produced weight loss, although more person-to-person contact produced more significant outcomes. Reductions in expression of IL-2 were related to weight loss.

Abstract
OBJECTIVE To determine the proportion of endometrial cancer patients who can be safely prescribed community/home based unsupervised exercise. A better understanding of the physical dysfunction secondary to comorbidities among endometrial cancer patients would assist clinicians in delineating which patients to send to medically-based supervised rehabilitation versus a community/home based unsupervised exercise program. METHODS A literature review identified health issues which could impede patients from successfully completing an unsupervised exercise program after a cancer diagnosis. The charts of 479 endometrial cancer patients treated between 2006 and 2010 were reviewed to determine the health status at the time of diagnosis and the type and percentage of health-issues that could preclude an unsupervised exercise program in this population. Univariable modeling and multivariable modeling were used to evaluate the association of demographic, cancer-related characteristics and clinical variables with ability to participate in unsupervised exercise. RESULTS We determined that 14.2% of endometrial cancer patients were able to exercise without supervision based on their health status at the time of diagnosis. After excluding common comorbidities (hypertension, diabetes and morbid obesity) from the identified health-issues, the proportion increased to 20.5%. Older at diagnosis (P=0.007) and higher BMI (P<0.001) are more likely to exclude patients from community/home based unsupervised exercise program. CONCLUSIONS Only 14.2% to 20.5% of endometrial cancer patients were deemed able to exercise without supervision based on their health status at diagnosis. Our data suggest that approximately 80% of endometrial cancer patients would benefit from a referral to a medically-based supervised exercise program.
