Abstract
BACKGROUND Magnetic resonance spectroscopy (MRS) has been used to investigate metabolic changes within human bone. It may be possible to use MRS to investigate bone metabolism and fracture risk in the distal third metacarpal/tarsal bone (MC/MTIII) in racehorses. OBJECTIVES To determine the feasibility of using MRS as a quantitative imaging technique in equine bone by using the 1H spectra for the MC/MTIII to calculate fat content (FC). STUDY DESIGN Observational cross-sectional study. METHODS Limbs from Thoroughbred racehorses were collected from horses that died or were subjected to euthanasia on racecourses. Each limb underwent magnetic resonance imaging (MRI) at 3 T followed by single-voxel MRS at three regions of interest (ROI) within MC/MTIII (lateral condyle, medial condyle, proximal bone marrow [PBM]). Percentage FC was calculated at each ROI. Each limb underwent computed tomography (CT) and bone mineral density (BMD) was calculated for the same ROIs. All MR and CT images were graded for sclerosis. Histology slides were graded for sclerosis and proximal marrow space was calculated. Pearson or Spearman correlations were used to assess the relationship between BMD, FC and marrow space. Kruskal-Wallis tests were used to check for differences between sclerosis groups for BMD or FC. RESULTS Eighteen limbs from 10 horses were included. A negative correlation was identified for mean BMD and FC for the lateral condyle (correlation coefficient = -0.60, p = 0.01) and PBM (correlation coefficient = -0.5, p = 0.04). There was a significant difference between median BMD for different sclerosis grades in the condyles on both MRI and CT. A significant difference in FC was identified between sclerosis groups in the lateral condyle on MRI and CT. MAIN LIMITATIONS Small sample size. CONCLUSIONS 1H Proton MRS is feasible in the equine MC/MTIII. Further work is required to evaluate the use of this technique to predict fracture risk in racehorses.

Abstract
Objective: Recent studies on Long COVID found that patients report prominent emotional distress and significant correlations between distress and cognitive performance have been identified, raising the question of how to manage or treat these issues. To understand psychological functioning in Long COVID further, this study examined personality responses on the Personality Assessment Inventory (PAI) to compare psychological functioning in a Long COVID group with a post-concussion syndrome (PCS) group, a syndrome with a significant psychological component. Participants and methods: Participants included 201 consecutive Long COVID outpatients (Mean age = 48.87 years, mean education = 14.82, 71.6% Female, 82.6% White) and a comparison group of 102 consecutively referred PCS outpatients (Mean age = 46.08, mean education = 14.17, 63.7% Female, 88.2% White). Effect sizes and t-tests were calculated using the PAI validity, clinical, interpersonal, and treatment consideration scales as well as clinical subscales. Results: The results replicated earlier findings on the PAI in Long COVID by demonstrating that both Long COVID and PCS groups had the highest mean elevations on SOM and DEP scales but no statistically significant between group differences in mean scale elevations. Results support similarities in psychological functioning between Long COVID and PCS patients emphasizing the importance of evaluating psychological functioning in neuropsychological evaluations for these populations. Further, results suggest that psychological treatment strategies for PCS patients may be helpful for Long COVID patients, but more research is needed.

Abstract
Fallopian tube pathology in patients with BRCA1 and BRCA2 mutations suggests a possible pathway to high grade serous ovarian carcinoma originates with a p53 signature, which is thought to represent a potential precursor to serous tubal intraepithelial carcinoma (STIC). The clinical implications of an isolated p53 signature in the average-risk population has not been well-established. This study aims to describe clinical outcomes in patients with incidentally noted p53 signature lesions. All patients diagnosed with a p53 signature lesion on final pathology from 2014 to 2022 were identified at a large academic institution. P53 signature is defined by our lab as morphologically normal to mildly atypical tubal epithelium with focal p53 over-expression on immunohistochemistry. Incidental p53 signature was defined as identification of a fallopian tube lesion excised for benign or unrelated indications in patients without a known hereditary disposition. Demographic, clinicopathologic, and genetic data were collected. A total of 127 patients with p53 signatures were identified. Thirty-six patients were excluded for established ovarian cancer or high-risk history leaving 91 total patients. Five patients (5.5%) developed a malignancy, none of which were ovarian or primary peritoneal, at the end of the eight and a half year follow up period. Twenty-four (26.4%) patients had salpingectomy without any form of oophorectomy at the time of initial surgery, while 67 (73.6%) patients had at least a unilateral oophorectomy at the time of their salpingectomy. Seven patients (7.7%) had additional surgery after p53 signature diagnosis; however, the final pathology yielded no evidence of malignancy in all these patients. After subsequent surgeries, 19 (20.9%) patients maintained their ovaries. The diagnosis of an incidental p53 signature was not associated with any primary peritoneal or ovarian cancer diagnoses during our follow up, and the majority of patients were managed conservatively by their providers with no further intervention after diagnosis.

Abstract
OBJECTIVES Optimal management of obese patients with early-stage cervical cancer is debated despite evidence of non-inferior survival in obese patients undergoing radical hysterectomy with pelvic lymphadenectomy (RH) compared to primary radiation with or without radiosensitizing chemotherapy (RT). Objectives included describing patient factors affecting disposition to RH versus RT; comparing RH outcomes for obese (BMI >30 mg/m2) and non-obese patients; and comparing differences in recurrence free survival (RFS) and overall survival (OS). METHODS This was a single institution cohort study of all cervical cancer patients who underwent RH or were candidates for RH based on clinical stage. Demographic, clinicopathologic and treatment outcomes were collected and analyzed. RESULTS RT patients (n = 39, 15%) had a higher BMI (p = 0.004), older age (p < 0.001), more life-limiting comorbidities (LLC) (p < 0.001), larger tumor size (p = 0.001), and higher clinical stage (p = 0.013) compared to RH patients (n = 221, 85%). On multivariable survival analysis there was no difference in OS based on treatment modality; significant predictors of worse OS were larger tumor size, higher number of LLC and recurrence. Among the RH group, obese patients had a longer operative time (p = 0.01) and more LLC (p = 0.02); there were no differences in demographic or clinicopathologic characteristics, operative outcomes, RFS or OS compared to non-obese patients. CONCLUSION In this cohort of RH-eligible cervical cancer patients, BMI was independently associated with disposition to RT. Studies demonstrate that RH is feasible and safe in obese patients with no difference in RFS or OS when compared to non-obese patients. Thus, the decision for disposition to RT should not be based on obesity alone.

Abstract
Background Somatic loss of the tumour suppressor RB1 is a common event in tubo-ovarian high-grade serous carcinoma (HGSC), which frequently co-occurs with alterations in homologous recombination DNA repair genes including BRCA1 and BRCA2 (BRCA). We examined whether tumour expression of RB1 was associated with survival across ovarian cancer histotypes (HGSC, endometrioid (ENOC), clear cell (CCOC), mucinous (MOC), low-grade serous carcinoma (LGSC)), and how co-occurrence of germline BRCA pathogenic variants and RB1 loss influences long-term survival in a large series of HGSC. Patients and methods RB1 protein expression patterns were classified by immunohistochemistry in epithelial ovarian carcinomas of 7436 patients from 20 studies participating in the Ovarian Tumor Tissue Analysis consortium and assessed for associations with overall survival (OS), accounting for patient age at diagnosis and FIGO stage. We examined RB1 expression and germline BRCA status in a subset of 1134 HGSC, and related genotype to survival, tumour infiltrating CD8+ lymphocyte counts and transcriptomic subtypes. Using CRISPR-Cas9, we deleted RB1 in HGSC cell lines with and without BRCA1 mutations to model co-loss with treatment response. We also performed genomic analyses on 126 primary HGSC to explore the molecular characteristics of concurrent homologous recombination deficiency and RB1 loss. Results RB1 protein loss was most frequent in HGSC (16.4%) and was highly correlated with RB1 mRNA expression. RB1 loss was associated with longer OS in HGSC (hazard ratio [HR] 0.74, 95% confidence interval [CI] 0.66-0.83, P = 6.8 ×10-7), but with poorer prognosis in ENOC (HR 2.17, 95% CI 1.17-4.03, P = 0.0140). Germline BRCA mutations and RB1 loss co-occurred in HGSC (P < 0.0001). Patients with both RB1 loss and germline BRCA mutations had a superior OS (HR 0.38, 95% CI 0.25-0.58, P = 5.2 ×10-6) compared to patients with either alteration alone, and their median OS was three times longer than non-carriers whose tumours retained RB1 expression (9.3 years vs. 3.1 years). Enhanced sensitivity to cisplatin (P < 0.01) and paclitaxel (P < 0.05) was seen in BRCA1 mutated cell lines with RB1 knockout. Among 126 patients with whole-genome and transcriptome sequence data, combined RB1 loss and genomic evidence of homologous recombination deficiency was correlated with transcriptional markers of enhanced interferon response, cell cycle deregulation, and reduced epithelial-mesenchymal transition in primary HGSC. CD8+ lymphocytes were most prevalent in BRCA-deficient HGSC with co-loss of RB1. Conclusions Co-occurrence of RB1 loss and BRCA mutation was associated with exceptionally long survival in patients with HGSC, potentially due to better treatment response and immune stimulation.

Abstract
Microdamage accumulated through sustained periods of cyclic loading or single overloading events contributes to bone fragility through a reduction in stiffness and strength. Monitoring microdamage in vivo remains unattainable by clinical imaging modalities. As such, there are no established computational methods for clinical fracture risk assessment that account for microdamage that exists in vivo at any specific timepoint. We propose a method that combines multiple clinical imaging modalities to identify an indicative surrogate, which we term 'hidden porosity', that incorporates pre-existing bone microdamage in vivo. To do so, we use the third metacarpal bone of the equine athlete as an exemplary model for fatigue induced microdamage, which coalesces in the subchondral bone. N = 10 metacarpals were scanned by clinical quantitative computed tomography (QCT) and magnetic resonance imaging (MRI). We used a patch-based similarity method to quantify the signal intensity of a fluid sensitive MRI sequence in bone regions where microdamage coalesces. The method generated MRI-derived pseudoCT images which were then used to determine a pre-existing damage (Dpex) variable to quantify the proposed surrogate and which we incorporate into a nonlinear constitutive model for bone tissue. The minimum, median, and maximum detected Dpex of 0.059, 0.209, and 0.353 reduced material stiffness by 5.9%, 20.9%, and 35.3% as well as yield stress by 5.9%, 20.3%, and 35.3%. Limb-specific voxel-based finite element meshes were equipped with the updated material model. Lateral and medial condyles of each metacarpal were loaded to simulate physiological joint loading during gallop. The degree of detected Dpex correlated with a relative reduction in both condylar stiffness (p = 0.001, R2 > 0.74) and strength (p < 0.001, R2 > 0.80). Our results illustrate the complementary value of looking beyond clinical CT, which neglects the inclusion of microdamage due to partial volume effects. As we use clinically available imaging techniques, our results may aid research beyond the equine model on fracture risk assessment in human diseases such as osteoarthritis, bone cancer, or osteoporosis.

Abstract
OBJECTIVE Adult-onset leukoencephalopathy with axonal spheroids and pigmented glia (ALSP) is a rapidly progressive neurodegenerative disorder caused by mutations in the CSF1R gene and is characterized by white matter disease, seizures, motor and cognitive impairment, and personality change. However, the existing neuropsychological literature on ALSP is limited. This exploratory study describes the cognitive profile of patients diagnosed with CSF1R-related ALSP. METHODS 7 patients with genetically confirmed CSF1R-related ALSP (Mage = 43.71, SD = 1.6; Meducation = 15.71, SD = 1.89; 71% female; 100% white) underwent neuropsychological examination as part of a pre-bone-marrow transplant work-up. Patients completed tests assessing all standard cognitive domains. Given variability in tests between evaluations, domain means were calculated for each patient and used to calculate frequencies of poor (below average and exceptionally low range) cognitive performance by domain. RESULTS Two patients were asymptomatic at the time of the evaluation and performed in the low average to exceptionally high range across domains. Of the remaining patients, the average time between symptom onset and the neuropsychological evaluation was 1.6 years (SD = 0.55). Below average to exceptionally low range performances were most often observed in executive functioning (80%) and processing speed (80%) domains. 60% of symptomatic patients showed poor performances in attention, verbal skills, visual skills, and fine motor functioning domains. CONCLUSIONS Consistent with prior research, results suggest primarily frontal and subcortical system dysfunction. Neuropsychologists may be uniquely qualified to aid in detecting subtle cognitive changes in ALSP patients that may be critical for early detection of symptoms and treatment planning. Future studies should evaluate these findings in large and more diverse samples.

Abstract
OBJECTIVE The objective of this study was to examine the feasibility and success rate of intraoperative injection of radiotracer and blue dye performed by the surgeon without the use of preoperative lymphoscintigraphy for the detection of sentinel lymph nodes in clinically early stage vulvar cancer. METHODS All patients with clinically early stage vulvar cancer who underwent attempted sentinel lymph node biopsy using intraoperative injection of Technetium-99 m (99mTc) tracer and blue dye performed by the surgeon after induction of anesthesia at single academic institution from 12/2009 to 5/2022 were identified. Demographic and clinicopathologic variables were collected. Data were compared using descriptive statistics. RESULTS One hundred sixty-four patients (median age 66.4 years) underwent intraoperative injection of radioactive tracer and dye for sentinel lymph node biopsy. Most patients (n = 156, 95.1%) were white. Squamous cell carcinoma accounted for 138 cases (84.1%), melanoma for 10 (6.1%), extra-mammary invasive Paget's disease for 11 (6.7%), and other histologies for 5 (3%). A majority of cases were stage I disease on final pathology (n = 119, 72.6%). Most patients (n = 117, 71%) had tumors located within 2 cm of the midline and underwent planned bilateral groin assessment, while 47 (29%) had well lateralized lesions and underwent unilateral groin assessment. For the patients undergoing unilateral groin assessment, 44 of 47 (93.6%) had successful unilateral mapping. Of the patients who underwent bilateral groin assessment, 87 of 117 (74.4%) had successful bilateral mapping, and 26 of 117 (22.2%) had successful unilateral mapping. Of the 26 patients who underwent bilateral assessment but only had unilateral mapping, 19 had unilateral mapping to ipsilateral groin but failed contralateral mapping, six had midline lesions with successful mapping to one groin but failed mapping to the other groin, and one had unilateral mapping to the contralateral groin but not ipsilateral groin. The total successful sentinel lymph node mapping rate in this cohort was 86.5% (243/281 total sentinel lymph node attempts). CONCLUSION In this cohort, the overall success rate of sentinel lymph node mapping and biopsy was 86.5%. The high rate of successful sentinel lymph node mapping supports the use of intraoperative radiotracer and blue dye injection by trained providers.

Abstract
BACKGROUND The role of ovulation in epithelial ovarian cancer (EOC) is supported by the consistent protective effects of parity and oral contraceptive use. Whether these factors protect through anovulation alone remains unclear. We explored the association between lifetime ovulatory years (LOY) and EOC. METHODS LOY was calculated using 12 algorithms. Odds ratios (ORs) and 95% confidence intervals (CIs) estimated the association between LOY or LOY components and EOC among 26 204 control participants and 21 267 case patients from 25 studies. To assess whether LOY components act through ovulation suppression alone, we compared beta coefficients obtained from regression models with expected estimates assuming 1 year of ovulation suppression has the same effect regardless of source. RESULTS LOY was associated with increased EOC risk (OR per year increase = 1.014, 95% CI = 1.009 to 1.020 to OR per year increase = 1.044, 95% CI = 1.041 to 1.048). Individual LOY components, except age at menarche, also associated with EOC. The estimated model coefficient for oral contraceptive use and pregnancies were 4.45 times and 12- to 15-fold greater than expected, respectively. LOY was associated with high-grade serous, low-grade serous, endometrioid, and clear cell histotypes (ORs per year increase = 1.054, 1.040, 1.065, and 1.098, respectively) but not mucinous tumors. Estimated coefficients of LOY components were close to expected estimates for high-grade serous but larger than expected for low-grade serous, endometrioid, and clear cell histotypes. CONCLUSIONS LOY is positively associated with nonmucinous EOC. Differences between estimated and expected model coefficients for LOY components suggest factors beyond ovulation underlie the associations between LOY components and EOC in general and for non-HGSOC.

Abstract
BACKGROUND Standard of care for adjuvant treatment of stage III endometrial cancer includes chemotherapy and radiation. In addition to stage, tumor molecular profiles may predict treatment outcomes, and prospective clinical trials are ongoing. However, tumor molecular testing is costly and time-consuming. Our objective was to evaluate the cost-effectiveness of tumor molecular testing in stage III endometrial cancer. METHODS A Markov decision model compared two strategies for stage III endometrial cancer: Tumor Molecular Testing (TMT) versus No TMT. TMT included sequential POLE next generation sequencing, mismatch repair immunohistochemistry (IHC), and p53 IHC. POLE-mutated patients were assigned to adjuvant radiation therapy; all others including controls were assigned to adjuvant chemoradiation. First recurrences were treated with 6 cycles of carboplatin and paclitaxel. Second recurrences were treated with pembrolizumab alone for mismatch repair deficient patients and both pembrolizumab and lenvatinib for other patients. Sensitivity analyses were performed to test model robustness. RESULTS Compared to No TMT, TMT was cost saving with equivalent effectiveness. On one-way sensitivity analysis, TMT remained cost saving over all parameter ranges. TMT was also favored on probabilistic sensitivity analysis in 80% of iterations at a willingness-to-pay threshold of $100,000/quality adjusted life-year (QALY) gained. However, when TMT was compared to mismatch repair IHC alone, TMT cost $182,798/QALY gained. CONCLUSIONS In this model of patients with stage III endometrial cancer, TMT was cost saving compared to No TMT. However, when compared to mismatch repair IHC alone, TMT was economically unfavorable.

Abstract
BACKGROUND Cyclin E1 (CCNE1) is a potential predictive marker and therapeutic target in tubo-ovarian high-grade serous carcinoma (HGSC). Smaller studies have revealed unfavorable associations for CCNE1 amplification and CCNE1 overexpression with survival, but to date no large-scale, histotype-specific validation has been performed. The hypothesis was that high-level amplification of CCNE1 and CCNE1 overexpression, as well as a combination of the two, are linked to shorter overall survival in HGSC. METHODS Within the Ovarian Tumor Tissue Analysis consortium, amplification status and protein level in 3029 HGSC cases and mRNA expression in 2419 samples were investigated. RESULTS High-level amplification (>8 copies by chromogenic in situ hybridization) was found in 8.6% of HGSC and overexpression (>60% with at least 5% demonstrating strong intensity by immunohistochemistry) was found in 22.4%. CCNE1 high-level amplification and overexpression both were linked to shorter overall survival in multivariate survival analysis adjusted for age and stage, with hazard stratification by study (hazard ratio [HR], 1.26; 95% CI, 1.08-1.47, p = .034, and HR, 1.18; 95% CI, 1.05-1.32, p = .015, respectively). This was also true for cases with combined high-level amplification/overexpression (HR, 1.26; 95% CI, 1.09-1.47, p = .033). CCNE1 mRNA expression was not associated with overall survival (HR, 1.00 per 1-SD increase; 95% CI, 0.94-1.06; p = .58). CCNE1 high-level amplification is mutually exclusive with the presence of germline BRCA1/2 pathogenic variants and shows an inverse association to RB1 loss. CONCLUSION This study provides large-scale validation that CCNE1 high-level amplification is associated with shorter survival, supporting its utility as a prognostic biomarker in HGSC.

Abstract
BACKGROUND Uterine clear cell carcinoma is a rare and aggressive subtype of endometrial carcinoma. Prospective clinical trials have not been feasible for this rare tumor, and data regarding the optimal adjuvant treatment regimen for early-stage uterine clear cell carcinomas is limited. Our study's objective was to determine if adjuvant chemotherapy or radiation therapy improves patients' outcomes in stage I and II uterine clear cell carcinoma. METHODS Patients with stage I and II uterine clear cell carcinoma were identified at a single institution. All cases were reviewed by a gynecologic pathologist. Both pure and mixed non-serous uterine clear cell carcinomas were included. Primary outcomes were recurrence free survival and overall survival. RESULTS A total of 71 patients were identified including 39 (55%) pure and 32 (45%) mixed clear cell carcinoma. Most patients were FIGO stage IA (77.5%). Most patients (n = 58, 82%) received adjuvant therapy, including 43 (61%) receiving chemotherapy, 50 (70%) receiving radiation therapy, and 35 (49%) receiving both. Recurrence free survival was not significantly different among patients receiving no or <6 cycles of chemotherapy versus patients receiving 6 cycles of chemotherapy (p = 0.39). However, median OS was significantly different among patients receiving no or <6 cycles of chemotherapy versus 6 cycles of chemotherapy (p = 0.004). On univariable analysis, 6 cycles of chemotherapy was significantly associated with improved OS (HR 0.1, 95% CI 0.01-0.07). Presence of LVSI, mutated p53, number of pelvic and para-aortic lymph nodes assessed, adjuvant chemotherapy (any number of cycles), and >2 medical co-morbidities were not significant predictors of OS on univariable analysis. On multivariable analysis, 6 cycles of adjuvant chemotherapy remained a significant predictor of improved OS (HR 0.1, 95% CI 0.01-0.8). CONCLUSIONS In this study, administration of 6 cycles of chemotherapy appears to significantly improve OS. This finding suggests consideration of 6 cycles of adjuvant chemotherapy in patients with early-stage uterine clear cell carcinoma, however clinical trials are needed to confirm these findings.

Abstract
BACKGROUND Recently, we showed a >60% difference in 5-year survival for patients with tubo-ovarian high-grade serous carcinoma (HGSC) when stratified by a 101-gene mRNA expression prognostic signature. Given the varied patient outcomes, this study aimed to translate prognostic mRNA markers into protein expression assays by immunohistochemistry and validate their survival association in HGSC. METHODS Two prognostic genes, FOXJ1 and GMNN, were selected based on high-quality antibodies, correlation with protein expression and variation in immunohistochemical scores in a preliminary cohort (n = 134 and n = 80, respectively). Six thousand four hundred and thirty-four (FOXJ1) and 5470 (GMNN) formalin-fixed, paraffin-embedded ovarian neoplasms (4634 and 4185 HGSC, respectively) represented on tissue microarrays from the Ovarian Tumor Tissue Analysis consortium underwent immunohistochemical staining and scoring, then univariate and multivariate survival analysis. RESULTS Consistent with mRNA, FOXJ1 protein expression exhibited a linear, increasing association with improved overall survival in HGSC patients. Women with >50% expression had the most favourable outcomes (HR = 0.78, 95% CI 0.67-0.91, p < 0.0001). GMNN protein expression was not significantly associated with overall HSGC patient survival. However, HGSCs with >35% GMNN expression showed a trend for better outcomes, though this was not significant. CONCLUSION We provide foundational evidence for the prognostic value of FOXJ1 in HGSC, validating the prior mRNA-based prognostic association by immunohistochemistry.

Abstract
BACKGROUND Although mental health symptoms increased during the coronavirus disease 2019 (COVID-19) pandemic, little is known about the associations between nursing students' perceived risk of contracting COVID-19 and their academic and psychological well-being. This study examined associations between perceived COVID-19 risk, likelihood of completing nursing education, and mental health factors of nursing students. METHOD A total of 979 nursing students completed self-report measures of perceived COVID-19 risk, anticipated academic completion, anxiety and depressive symptoms, stress, coping self-efficacy, hope, and social support. RESULTS Students with higher perceived COVID-19 risk reported increased anxiety and depression as well as decreased likelihood of graduating, coping self-efficacy, and levels of social support. CONCLUSION Findings indicate the need for increased mental health support for nursing students for successful completion of their programs. Educators should increase support and proactively strengthen positive psychology factors to mitigate the effects of COVID-19 and other crises on nursing students' well-being.

Abstract
BACKGROUND New therapeutic combinations to improve the outcome of ovarian cancer patients are clearly needed. Preclinical studies with ribociclib (LEE-011), a CDK4/6 cell cycle checkpoint inhibitor, demonstrate a synergistic effect with platinum chemotherapy and efficacy as a maintenance therapy after chemotherapy. We tested the safety and initial efficacy of ribociclib in combination with platinum-based chemotherapy in recurrent ovarian cancer. METHODS This phase I trial combined weekly carboplatin and paclitaxel chemotherapy with ribociclib followed by ribociclib maintenance in patients with recurrent platinum-sensitive ovarian cancer. Primary objectives were safety and maximum tolerated dose (MTD) of ribociclib when given with platinum and taxane chemotherapy. Secondary endpoints were response rate (RR) and progression-free survival (PFS). RESULTS Thirty-five patients were enrolled. Patients had a mean 2.5 prior lines of chemotherapy, and 51% received prior maintenance therapy with Poly (ADP-ribose) polymerase inhibitors (PARPi) and/or Bevacizumab. The MTD was 400mg. The most common AEs included anemia (82.9%), neutropenia (82.9%), fatigue (82.9%), and nausea (77.1%). Overall RR was 79.3% with a stable disease (SD) rate of 18% resulting in a clinical benefit rate of 96.6%. The PFS was 11.4 months. RR and PFS did not differ based on number of lines of prior chemotherapy or prior maintenance therapy. CONCLUSIONS This work demonstrates the combination of ribociclib with chemotherapy in ovarian cancer is feasible and safe. With a clinical benefit rate of 97%, this work provides encouraging evidence of clinical efficacy in patients with recurrent platinum-sensitive disease. TRIAL REGISTRATION CLINICALTRIALS gov NCT03056833. FUNDING This investigator-initiated trial was supported by Novartis who provided drug and funds for trial execution.

Abstract
Abstract
Uterine serous carcinoma (USC) is a highly aggressive endometrial cancer subtype with limited therapeutic options and a lack of targeted therapies. While mutations to PPP2R1A, encoding the predominant protein phosphatase 2A (PP2A) scaffolding protein Aα, occur in 30-40% of cases, the clinical actionability of these mutations has not been studied. Here, we show that mutation to Aα results in synthetic lethality to treatment with inhibitors of ribonucleotide reductase (RNR), and multiple models of Aα mutant uterine serous tumors were sensitive to Clofarabine, an RNR inhibitor in vivo. Aα mutant cells displayed impaired checkpoint signaling upon RNRi treatment, and subsequently accumulated more DNA damage than wild type cells. This was PP2A dependent as complete inhibition of PP2A activity using LB-100, a catalytic site inhibitor, sensitized wild type USC cells to RNRi. Analysis of TCGA data indicated that inactivation of PP2A, through loss of PP2A subunit expression, was prevalent in USC, with 88% of USC patients harboring loss of at least one PP2A gene. In contrast, loss of PP2A subunit expression was rare in uterine endometrioid carcinomas. While RNR inhibitors are not routinely used for uterine cancers, we identified a cohort of patients with recurrent disease treated with gemcitabine at MSKCC as a second or later line therapy. In a retrospective analysis of this cohort there was a trend for improved outcomes in USC patients treated with RNRi gemcitabine compared to patients with endometrioid histology. Overall, our data provide experimental evidence to support the use of ribonucleotide reductase inhibitors for the treatment of USC.

Abstract
Abstract
Despite years of prostate cancer-related research, balancing the risk of treatment-derived complications with tumor progression risk remains a challenge. The inability to dissect heterogeneous tumor microenvironments (TME) and immune compartments partly contribute to this knowledge gap. Spatially resolved molecular tumor profiling can enhance our understanding of these complexities and bring us closer to personalized treatment; however, deploying such methods in oncology workflows is challenging as the prevalent tissue preservation technique of formalin fixation and paraffin embedding (FFPE) leads to RNA degradation.We used tissue-wide whole transcriptome analysis with 10x Genomics Visium Spatial Gene Expression Solution for FFPE tissue to resolve the tumor microenvironment of two prostate cancer samples. This assay incorporates ~5,000 molecularly barcoded, spatially encoded capture probes in spots over which the tissue is placed, imaged, and permeabilized. Imaging and sequencing data are processed together for spatially resolved transcriptional readout. We analyzed, and resolved whole transcriptome tumorigenic profiles in sections of normal, stage III invasive adenocarcinoma, and stage IV acinar cell carcinoma FFPE human prostate tissues. Computational clustering of the whole-transcriptome data automatically identified spatial gene expression patterns that aligned well with pathologist annotations. Well known prostate gland and prostate cancer markers were over-expressed in the corresponding healthy and cancerous tumor tissue, validating this method. The data showed that basal cells and luminal cells are spatially organized in healthy tissue while this pattern is lost in tumor samples as the luminal cells encroach the invasive carcinoma region and do not colocalize with basal cells. Moreover, T lymphocytes are dispersed throughout the whole tissue in the adenocarcinoma, while plasma B cells are in the peritumoral region which could impact prognosis. Using computational methods to infer CNV profiles, we identified aneuploidy regions and specific loci that may be driving the underlying genomic profile of the cancerous regions. We demonstrated that spatial whole transcriptome analysis can successfully resolve FFPE prostate samples. Whole-transcriptome data can rapidly confirm known patterns of cell type and tumor region-specific gene expression while giving a better understanding of the TME for drug target identification or biomarker discovery that may lead to patient-tailored therapies and improved patient stratification.

Abstract
Controversy persists regarding metformin's role in cancer therapy. Our recent work suggested metformin acts by impacting the tumor microenvironment (TME), normalizing the epigenetic profile of cancer-associated mesenchymal stem cells (CA-MSC). As CA-MSC can negatively impact tumor immune infiltrates, we evaluated metformin's impact on the human TME, focusing on the interplay of stroma and immune infiltrates. Tumor samples from (i) 38 patients treated with metformin and chemotherapy and (ii) 44 non-metformin matched controls were included in a tissue microarray (TMA). The TMA was used to compare the presence of CA-MSC, desmoplasia and immune infiltrates in the TME. In vitro and in vivo models examined metformin's role in alteration of the CA-MSC phenotype. The average percentage of CA-MSC was significantly lower in metformin-treated than in chemotherapy alone-treated tumors (p = 0.006). There were fewer regulatory T-cells in metformin-treated tumors (p = 0.043). Consistent with CA-MSC's role in excluding T-cells from tumor islets, the T-cells were primarily present within the tumor stroma. Evaluation of metformin's impact in vitro suggested that metformin cannot reverse a CA-MSC phenotype; however, the in vivo model where metformin was introduced prior to the establishment of the CA-MSC phenotype supported that metformin can partially prevent the reprogramming of normal MSC into CA-MSC. Metformin treatment led to a decrease in both the presence of protumorigenic CA-MSC and in immune exclusion of T cells, leading to a more immune-permissive environment. This suggests clinical utility in prevention and in treatment for early-stage disease and putatively in immune therapy.

Abstract
Uterine sarcomas are rare mesenchymal tumors that are aggressive cancers. The rarity of these tumors, and consequently limited prospective data, has made surgical management of uterine sarcomas challenging. One major obstacle in the management of uterine sarcomas is establishing the diagnosis prior to surgery, which is crucial for appropriate intraoperative management. This paper serves to review aspects of surgical management of uterine sarcomas that remain unanswered. Distinguishing common benign myomas from rare uterine sarcomas is important for operative planning and subspecialty care because benign myomas are frequently managed with minimally invasive hysterectomy or myomectomy, whereas the mainstay of management of uterine sarcomas is hysterectomy without specimen fragmentation. Preoperative clinical presentation, serum studies, imaging, and histologic examination all have limitations in establishing a preoperative diagnosis. In addition, patients are often of reproductive age and desire fertility preservation. Although surgery remains the cornerstone for management, high-quality data guiding best practices are sparse. Morcellation should be avoided. Expert pathologic review, imaging to assess for metastatic disease, and consideration of hormone receptor testing are advisable. Recent data have further informed surgical approach and fertility preservation in early-stage disease, but controversy remains. Despite substantial advancement in the medical management of uterine sarcomas, surgical management of uterine sarcomas remain challenging. Larger studies with long-term follow-up are needed to guide fertility preservation surgery options, both local resection and ovarian preservation, further in young women. Development of novel methods to differentiate between benign and malignant uterine masses is needed.

Abstract
Uterine serous carcinoma (USC) is a highly aggressive endometrial cancer subtype with limited therapeutic options and a lack of targeted therapies. While mutations to PPP2R1A, which encodes the predominant protein phosphatase 2A (PP2A) scaffolding protein Aα, occur in 30% to 40% of USC cases, the clinical actionability of these mutations has not been studied. Using a high-throughput screening approach, we showed that mutations in Aα results in synthetic lethality following treatment with inhibitors of ribonucleotide reductase (RNR). In vivo, multiple models of Aα mutant uterine serous tumors were sensitive to clofarabine, an RNR inhibitor (RNRi). Aα-mutant cells displayed impaired checkpoint signaling upon RNRi treatment and subsequently accumulated more DNA damage than wild-type (WT) cells. Consistently, inhibition of PP2A activity using LB-100, a catalytic inhibitor, sensitized WT USC cells to RNRi. Analysis of The Cancer Genome Atlas data indicated that inactivation of PP2A, through loss of PP2A subunit expression, was prevalent in USC, with 88% of patients with USC harboring loss of at least one PP2A gene. In contrast, loss of PP2A subunit expression was rare in uterine endometrioid carcinomas. While RNRi are not routinely used for uterine cancers, a retrospective analysis of patients treated with gemcitabine as a second- or later-line therapy revealed a trend for improved outcomes in patients with USC treated with RNRi gemcitabine compared with patients with endometrioid histology. Overall, our data provide experimental evidence to support the use of ribonucleotide reductase inhibitors for the treatment of USC. SIGNIFICANCE A drug repurposing screen identifies synthetic lethal interactions in PP2A-deficient uterine serous carcinoma, providing potential therapeutic avenues for treating this deadly endometrial cancer.

Abstract
OBJECTIVE Long-term cognitive sequelae of COVID-19 have not been extensively studied. This study provides initial results on cognitive outcomes in Post-Acute Sequelae of COVID-19 (PASC).Participants and Methods: This study examined 53 consecutive outpatients diagnosed with COVID-19. Four participants were excluded due to performance validity test failure. All participants had positive COVID-19 tests, reported cognitive concerns, and completed neuropsychological tests to assess performance validity, attention/working memory, processing speed, memory, language, visual-spatial, executive functioning, motor, and emotional functioning. The sample was mostly white (89.8%), female (83.7%), and never hospitalized (69.4%) for COVID-19. RESULTS Analyses indicated no mean scores in the Impaired range (>2 standard deviations [SD] below normative mean) on objective cognitive testing and a low base rate of Impaired test scores. Higher (>20%) base rates of Borderline performance (1-2 SDs below normative mean) were found on some measures. There was also evidence for frequently elevated mean scores on mood measures which correlated with some cognitive measures and the number of Borderline scores per participants. CONCLUSIONS The results were noteworthy for infrequent Impaired scores, and significant correlations between cognition and mood/anxiety measures, but not between cognitive performance and premorbid vascular risk factors, psychiatric diagnoses, or COVID-19 disease severity. Results suggest that psychological distress was prominent in PASC and related to objective cognitive performance, but objective cognitive performance was unrelated to cognitive complaints. Other contributing factors may include fatigue/sleep issues. Neurologically based cognitive deficits were not suggested by the results.During the COVID-19 pandemic, researchers and clinicians have gained considerable knowledge of the SARS-CoV-2 virus that causes the COVID-19 illness. Research has implicated COVID-19 in a variety of neurological and psychiatric issues (Taquet et al., 2021) including stroke, depression/anxiety, and more rarely intracranial hemorrhage and psychotic disorders. Further, various vascular risk factors such as hypertension, diabetes, hyperlipidemia, and obstructive sleep apnea (OSA) have been associated with more severe COVID-19 symptoms (Bauer et al., 2021; Luk et al., 2021; Mishra et al., 2020; Saxena et al., 2021). Additionally, while many patients recover from COVID-19 in a few weeks, a substantial number continue to experience physical (e.g., fatigue, shortness of breath, cough, palpitations) and cognitive (e.g., "brain fog", concentration and memory complaints) symptoms for a considerable period (Raveendran et al., 2021). It has also been suggested that patients themselves, via social media, contributed to reifying the phenomenon of "Long COVID-19" or post-acute sequelae of SARS-CoV-2 infection (PASC; Callard & Perego, 2021). However, very limited research exists that directly investigates the cognitive sequelae of COVID-19 infection, particularly in the long term. The current study aims to address this limitation in the literature.

Abstract
Limited research investigating the long-term psychological and emotional correlates of COVID-19 infection has been completed. The current study begins to address this limitation in patients experiencing Post-Acute Sequelae SARS-CoV-2 (PASC; e.g. "Long COVID"). Participants were 43 consecutive neuropsychological outpatients diagnosed with PASC and who completed the Personality Assessment Inventory (PAI). The sample was predominantly female (n = 36) and white (n = 32). Effect sizes compared to the normative mean T scores and base rates of elevated (T > 69) scores were calculated. PAI scales measuring somatic preoccupation and depression had large effect sizes and the highest base rates of scale elevations, with the mean T score at approximately the normative cutoff for clinical significance (T = 70). The Schizophrenia Thought Disorder subscale (SCZ-T) also had a large effect size and high base rate of elevation, likely reflecting cognitive concerns. Scales measuring anxiety had medium effect sizes. The other PAI scales generally had small to negligible effect sizes. There were no significant differences between hospitalized and non-hospitalized participants on the PAI. Overall, PAI scales measuring psychological distress, particularly somatic preoccupation and depression, were the most frequently elevated in the participants. The specific reasons for somatic preoccupation could not be determined in this study. Potential explanations include a vulnerability to distress in Long COVID patients, premorbid somatic preoccupation perhaps motivating these patients to seek clinical attention, or socioenvironmental factors leading some COVID patients to be somatically preoccupied with minor physiological changes and attribute those changes to COVID-19.

Abstract
Patterns of diversity in pathogen genomes provide a window into the spatiotemporal spread of disease. In this study, we tested the hypothesis that Schistosoma mansoni parasites form genetic clusters that coincide with the communities of their human hosts. We also looked for genetic clustering of parasites at the sub-community level. Our data consists of 14 microsatellite DNA markers, typed from pooled DNA samples from [Formula: see text] infected individuals living in three Brazilian communities. We found a one-to-one correspondence between genetic clusters found by K-means cluster analysis and communities when [Formula: see text]. These clusters are also easily identified in a neighbor-joining tree and principal coordinates plots. K-means analysis with [Formula: see text] also reveals genetic clusters of parasites at the sub-community level. These sub-clusters also appear on the neighbor-joining tree and principal coordinates plots. A surprising finding is a genetic relationship between subgroups in widely separated human communities. This connection suggests the existence of common transmission sites that have wide influence. In summary, the genetic structure of S. mansoni in Brazil juxtaposes local isolation that is occasionally broken by long-range migration. Permanent eradication of schistosomes will require both local efforts and the identification of regional infection reservoirs.

Abstract
PURPOSE Tumor molecular analyses in endometrial cancer (EC) includes 4 distinct subtypes: (1) POLE-mutated, (2) mismatch repair protein (MMR) deficient, (3) p53 mutant, and (4) no specific molecular profile. Recently, a sub-analysis of PORTEC-3 demonstrated notable differences in treatment response between molecular classification (MC) groups. Cost of testing is one barrier to widespread adoption of MC. Therefore, we sought to determine the cost-effectiveness of MC in patients with stage I and II high-risk EC. METHODS A Markov decision model was developed to compare tumor molecular classification (TMC) vs. no testing (NT). A healthcare payor's perspective and 5-year time horizon were used. Base case data were abstracted from PORTEC-3 and the molecular sub-analysis. Cost and utility data were derived from public databases, peer-reviewed literature, and expert input. Strategies were compared using the incremental cost-effectiveness ratio (ICER) with effectiveness in quality-adjusted life years (QALYs) and evaluated with a willingness-to-pay threshold of $100,000 per QALY gained. Sensitivity analyses were performed to test model robustness. RESULTS When compared to NT, TMC was cost effective with an ICER of $25,578 per QALY gained; incremental cost was $1780 and incremental effectiveness was 0.070 QALYs. In one-way sensitivity analyses, results were most sensitive to the cost of POLE testing, but TMC remained cost-effective over all parameter ranges. CONCLUSIONS TMC in early-stage high-risk EC is cost-effective, and the model results were robust over a range of parameters. Given that MC can be used to guide adjuvant treatment decisions, these findings support adoption of TMC into routine practice.

Abstract
Introduction: The COVID pandemic has significantly impacted educational development and delivery, yet there is little quantitative research on this topic. The primary objective of this study was to compare the total number of Emergency Medical Service (EMS) Refresher (ER) course completions during 2020 versus prior years. Secondary outcomes examined in person versus on-line/distributive learning during the study period. Methods: The Commission on Accreditation for Prehospital Continuing Education (CAPCE) is the only national organization that accredits continuing education (CE) for paramedics and EMTs and currently has a database with over 14 million CE records. The total number of ER course completions each month in 2020 were compared to 2019 and 2018. We also compared the different educational format types: live in-person (LIP), asynchronous on-line distributive learning (DL), and virtual instructor lead training (VILT) synchronous DL courses. Data was analyzed using descriptive and two-way ANOVA statistics. Results: There were 1,922,783 ER course completions in 2020 versus 1,166,335 in 2019 and 1,074,636 in 2018, representing a 179% increase during the study period. Asynchronous DL course completions in 2020 were 1,830,513 EMS versus 1,078,580 in 2019 and 987,749 in 2018 a 185% increase over the three-year study period. Asynchronous DL monthly means by year was statistically significant, F(2, 99) = 95.632, p < .001. Mean monthly LIP and VLIT educational deliveries by year were not significantly different, p = .802, p = .754, respectively. Total LIP course completions in 2020 were 20,045 versus 51,552 in 2019 and 63,058 in 2018. In 2020 LIP courses made up only 1.0% (20,045/1,922,783) of all ER completions. This study was limited to only EMS professionals taking ER course completions in the CAPCE database. However EMS is not unique, since previous research has suggested that DL has flourished in other health care disciplines while LIP courses have continued to decrease. Conclusion: This large nationwide study of EMS profession has shown the trend toward DL education and a trend away from LIP courses. Future studies should examine the advantages and disadvantages of DL education.

Abstract
e18838 Background: PORTEC-3, a phase III clinical trial comparing adjuvant radiation alone (RT) to combined chemoradiation therapy (CTRT) in patients with high-risk endometrial cancer (EC), demonstrated no benefit with CTRT compared to RT for patients with stage I and II EC. However, a subsequent tumor molecular analysis revealed that individuals with stage I and II high-risk EC with p53 mutations had statistically significantly improved progression-free survival (PFS) and clinically significantly improved overall survival (OS) with combined CTRT. As p53 immunohistochemical (IHC) testing and CTRT adds to cost and toxicity, we sought to evaluate the cost-effectiveness of p53 IHC tumor testing in patients with stage I and II high-risk EC. Methods: A Markov decision model was developed to compare two testing strategies in patients with stage I and II high-risk EC: p53 IHC testing vs. no IHC testing. IHC staining for p53 is an accurate and validated surrogate for TP53 mutational status. As a result, p53 IHC testing alone was used in the decision analysis. Data from PORTEC-3 and the subsequent molecular analysis were used for the base case model parameters, including treatment regimen, PFS, OS, and incidence of p53-mutated tumors. Cost and utility data were derived from the Federal Supply Schedule, the Centers for Medicare and Medicaid Services (CMS) Fee Schedules, the Tufts CEA registry, peer-reviewed literature, and expert input. Data analysis was performed using TreeAge Pro Software, 2021. Effectiveness outcomes included quality-adjusted life-years (QALYs) and incremental cost-effectiveness ratios (ICERs). Sensitivity analyses were performed in order to identify the influence of individual variables on the overall model. Results: When compared to no testing, p53 IHC testing resulted in a cost savings of $471 per patient while providing an additional 0.310 QALYs. Therefore, p53 IHC testing was less expensive and more effective than no IHC testing and was a dominant strategy in this model. In one-way sensitivity analyses, CTRT and RT costs, discount rate, and percentage of p53 mutations detected had the most impact on the model; however, p53 IHC testing remained a cost-saving strategy over all parameter ranges examined. Conclusions: For patients with high-risk stage I and II EC, this analysis suggests that p53 IHC testing is cost-effective compared to no testing in determining the costs and benefits of adjuvant chemotherapy. Although additional studies are warranted, this data provides further support for the role of molecular-based treatment decisions for high-risk stage I and II endometrial cancer.

Abstract
Although frequently associated with tumor progression, inflammatory cytokines initially restrain transformation by inducing senescence, a key tumor-suppressive barrier. Here, we demonstrate that the inflammatory cytokine, oncostatin M, activates a mesenchymal/stem cell (SC) program that engages cytokine-induced senescence (CIS) in normal human epithelial cells. CIS is driven by Snail induction and requires cooperation between STAT3 and the TGFβ effector, SMAD3. Importantly, as cells escape CIS, they retain the mesenchymal/SC program and are thereby bestowed with a set of cancer SC (CSC) traits. Of therapeutic importance, cells that escape CIS can be induced back into senescence by CDK4/6 inhibition, confirming that the mechanisms allowing cells to escape senescence are targetable and reversible. Moreover, by combining CDK4/6 inhibition with a senolytic therapy, mesenchymal/CSCs can be efficiently killed. Our studies provide insight into how the CIS barriers that prevent tumorigenesis can be exploited as potential therapies for highly aggressive cancers. IMPLICATIONS: These studies reveal how a normal cell's arduous escape from senescence can bestow aggressive features early in the transformation process, and how this persistent mesenchymal/SC program can create a novel potential targetability following tumor development.

Abstract
PURPOSE GOG 205 safely increased clinical (cCR) and pathologic complete response (pCR) in locally-advanced vulvar cancer through dose escalation using three-dimensional radiotherapy (RT). The aim of this study is to assess the response of dose-escalated intensity modulated radiotherapy (IMRT) in locally-advanced vulvar cancer. METHODS A retrospective review of patients treated with dose-escalated (≥ 55Gy) IMRT from 2012 to 2018 for locally-advanced vulvar cancer was performed. Patients treated with preoperative or definitive intent were included. Rates of cCR and pCR were assessed, and predictors of disease-free survival (DFS) were analyzed using the Kaplan Meier method with log rank test between groups and a parsimonious multivariate Cox model. RESULTS Median dose to the vulva was 66.0 Gy (Interquartile Range [IQR]: 66.0-68.0) for definitive and 59.4 Gy (IQR: 58.0-59.4) for preoperative IMRT. The overall rates of cCR and pCR were 76% and 70%, respectively. DFS at two years was 65% (95% Confidence Interval [CI] 50-80%) for all patients, 81% (95% CI 63% - 98%) for definitive IMRT, and 55% (95% CI 35% - 76%) for preoperative IMRT. On multivariate analysis, cCR predicted for disease-free survival (HR 0.21; 95% CI 0.06-0.76; p = 0.02), and pCR predicted for OS (HR 0.12; 95% CI 0.02-0.60; p = 0.01). Grade 3 acute and late RT toxicity was seen in 14 (29%) and 3 (6%) of patients, respectively. CONCLUSION Dose-escalated IMRT for locally-advanced vulvar cancer is well tolerated, with rates of cCR and pCR that compare favorably with published data.

Abstract
PROBLEM Previous studies identified circulating CD14+ HLA-DRlo/- monocytic cells as an immune suppressive subset in solid malignancies, such as prostate, renal cell carcinoma, and pancreatic cancer. Such monocytic cells have been implicated not only in tumour progression but also as a potential barrier for immunotherapy. This study examined the relationship between the frequency of circulating monocytic cells and epithelial ovarian cancer (EOC) progression pre- and post-frontline chemotherapy, defined by disease stage, which is a leading prognostic factor for this malignancy. METHOD OF STUDY Incident cases of 236 women with EOC were recruited and comprehensive flow cytometry was utilized to assess the frequency of peripheral blood CD33+ CD11b+ HLA-DR-/low CD14+ CD15- monocytic cells, henceforth termed CD14+ HLA-DRlo/- monocytic cells, prior to and after completion of frontline chemotherapy. Multivariable odds ratios (OR) were used to estimate the association between CD14+ HLA-DRlo/- monocytic cell percentages and disease stage. Wilcoxon signed-rank tests evaluated changes in these monocytic cell levels pre- and post-chemotherapy in a patient subset (n = 70). RESULTS Patients with elevated frequencies of circulating CD14+ HLA-DRlo/- monocytic cells at diagnosis were at 3.33-fold greater odds of having advanced stage (III/IV) EOC (CI: 1.04-10.64), with a significant trend in increasing CD14+ HLA-DRlo/- monocytic cell levels (P = .04). There was a 2.02% median decrease of these monocytic cells post-chemotherapy among a subset of patients with advanced stage disease (P < .0001). CONCLUSION These findings support the potential clinical relevance of CD14+ HLA-DRlo/- monocytic cells in EOC for prognosis and may indicate a non-invasive biomarker to measure disease progression.

Abstract
PURPOSE The Vienna and Venezia (Elekta) are hybrid intracavitary/interstitial brachytherapy (BT) applicators for cervical cancers unsuitable for intracavitary BT alone to improve target coverage or reduce critical organ dose. There is limited outcome data with the use of these applicators outside published experience of the EMBRACE group. We report feasibility and early outcomes with the use of these hybrid applicators at our institution. METHODS AND MATERIALS Hybrid applicators were used to treat 61 patients with cervical cancer from November 2011 to December 2019. Indications for hybrid applicator use were involvement of the vagina in 10 patients (16%), residual central or parametrial disease in 46 patients (75%), and a narrow introitus in 5 patients (9%). Toxicities were graded using the CTCAE v4.0. Outcomes were assessed with the Kaplan-Meier method. RESULTS Median follow-up was 16 months (IQR 9-32 mos). Median HRCTV volume was 31.6 cm3 (IQR 25-48 cm3). Median HRCTV D90 was 86.1 Gy (IQR 84.3-88.0 Gy). In 54 patients with follow-up PET/CT at 3 months, complete initial imaging response locally was seen in 46 patients.Estimated 12-month Kaplan-Meier overall survival, locoregional control, distant control, and recurrence-free survival estimates were 86.9%, 80.6%, 73.8%, and 65.9%, respectively. The 12-month incidence of Grade 3+ GI/GU chronic toxicities was 5.7%, consisting of vesicovaginal fistula, rectovaginal fistula, and ureterovesical fistula. CONCLUSIONS Our single-institution data support the use of the hybrid applicators, as an alternative to traditional BT applicators when clinically warranted. Use of hybrid applicators is feasible with adequate coverage of disease in the vagina and parametrium.

Abstract
Background Intraperitoneal/intravenous chemotherapy (IP/IV) was associated with improved survival for ovarian cancer (OC) patients in several randomized clinical trials. However, the uptake of IP/IV in clinical practice is varied due to conflicting evidence about its impact on survival and recurrence. The aim of this study was to explore the uptake of IP/IV treatment and to evaluate its impact on survival and recurrence in OC patients. Methods Demographic and clinical information on OC patients (N = 2916) who underwent treatment for OC between 2000 and 2017 was obtained from the large healthcare system cancer registry. Duplicate records, grade 1, rare (eg, gelatinous carcinoma), and non‐epithelial (eg, granulosa cell carcinoma) tumors were excluded. Kaplan‐Meier survival curves were constructed to compare 5‐ and 10‐year survival based on the chemotherapy type, surgery type, and stage. Multivariable Gray's piecewise constant time‐varying coefficient models were fitted to evaluate the effect of IP/IV on adjusted hazard ratio (AHR) of OC survival and recurrence adjusting for potential confounders. Results The final sample consisted of 1846 OC patients, 14% (250/1846) of which received IP/IV chemotherapy. IP/IV was significantly associated with improved 10‐year survival (P < .001). Multivariable Gray's model demonstrated that IP/IV therapy significantly reduced the AHR of death (AHR = 0.39‐1.07, P < .001) with the beneficial effect gradually declining over time. Use of IP/IV chemotherapy had no impact on OC recurrence. Conclusions These findings demonstrated that only a small fraction of eligible patients underwent IP/IV chemotherapy. We report a significant 10‐year survival, but not necessarily recurrence benefit is associated with IP/IV chemotherapy compared to IV only, suggesting the need for novel ways of identifying patients who may benefit from IP/IV chemotherapy.

Abstract
OBJECTIVES Methotrexate and actinomycin-D are both effective first-line drugs for low-risk (WHO score 0-6) Gestational Trophoblastic Neoplasia (GTN) with considerable debate about which is more effective, less toxic, and better tolerated. The primary trial objective was to test if treatment with multi-day methotrexate (MTX) was inferior to pulse actinomycin-D (ACT-D). Secondary objectives included evaluation of severity and frequency of adverse events, and impact on quality of life (QOL). METHODS This was a prospective international cooperative group randomized phase III two arm non-inferiority study (Clinical Trials Identifier: (NCT01535053). The control arm was ACT-D; the experimental arm was multi-day MTX regimen (institutional preference of 5 or 8 day). Outcome measures included complete response rate, recurrence rate, toxicity, and QOL as measured by FACT-G and FACIT supplemental items. RESULTS The complete response rates for multi-day methotrexate and pulse actinomycin-D were 88% (23/26 patients) and 79% (22/28 patients) (p = NS) respectively, there were two recurrences in each arm, and 100% of patients survived. Significant toxicity was minimal, but mouth sores (mucositis), and eye pain were significantly more common in the MTX arm (p = 0.001 and 0.01 respectively). Quality of life showed no significant difference in overall quality of life, body image, sexual function, or treatment related side effects. The study was closed for low accrual rate (target 384, actual accrual 57), precluding statistical analysis of the primary objective. CONCLUSIONS The complete response rate for multi-day methotrexate was higher than actinomycin-D, but did not reach statistical significance. The multi-day MTX regimens were associated with significantly more mucositis and were significantly less convenient.

Abstract
BACKGROUNDEpidemiologic studies suggest that metformin has antitumor effects. Laboratory studies indicate metformin impacts cancer stem-like cells (CSCs). As part of a phase II trial, we evaluated the impact of metformin on CSC number and on carcinoma-associated mesenchymal stem cells (CA-MSCs) and clinical outcomes in nondiabetic patients with advanced-stage epithelial ovarian cancer (EOC).METHODSThirty-eight patients with stage IIC (n = 1)/III (n = 25)/IV (n = 12) EOC were treated with either (a) neoadjuvant metformin, debulking surgery, and adjuvant chemotherapy plus metformin or (b) neoadjuvant chemotherapy and metformin, interval debulking surgery, and adjuvant chemotherapy plus metformin. Metformin-treated tumors, compared with historical controls, were evaluated for CSC number and chemotherapy response. Primary endpoints were (a) a 2-fold or greater reduction in aldehyde dehydrogenase-positive (ALDH+) CD133+ CSCs and (b) a relapse-free survival at 18 months of more than 50%.RESULTSMetformin was well tolerated. Median progression-free survival was 18.0 months (95% CI 14.0-21.6) with relapse-free survival at 18 months of 59.3% (95% CI 38.6-70.5). Median overall survival was 57.9 months (95% CI 28.0-not estimable). Tumors treated with metformin had a 2.4-fold decrease in ALDH+CD133+ CSCs and increased sensitivity to cisplatin ex vivo. Furthermore, metformin altered the methylation signature in CA-MSCs, which prevented CA-MSC-driven chemoresistance in vitro.CONCLUSIONTranslational studies confirm an impact of metformin on EOC CSCs and suggest epigenetic change in the tumor stroma may drive the platinum sensitivity ex vivo. Consistent with this, metformin therapy was associated with better-than-expected overall survival, supporting the use of metformin in phase III studies.TRIAL REGISTRATIONClinicalTrials.gov NCT01579812.

Abstract
e18045 Background: LGSC and serous ovarian LMP tumors are rare entities along a disease continuum. Because they are relatively chemotherapy resistant, there is interest in targeted treatment, including endocrine therapy. In studies of endocrine agents for treatment of recurrent ovarian cancer, tumor estrogen receptor (ER) status alone does not effectively predict outcomes. The objective of this study is to utilize protein and gene expression from ER and downstream targets to identify signaling components that will act as prognostic and predictive biomarkers. Methods: A single institution tumor registry was queried for patients with LGSC or serous LMP tumors between 1993-2016. Formalin-fixed, paraffin embedded (FFPE) tissue was obtained. Clinicopathologic data was collected. Immunohistochemistry (IHC) was performed and scored as dichotomous (+/-) and continuous (H-score). NanoString nCounter platform was used for gene expression of a predesigned endocrine biomarker panel. Wilcoxon Rank Sum was used to compare mRNA and protein expression. Survival analyses were performed using Cox proportional hazard (PH) method with elastic net to fit the prediction model for the gene panel. Results: Tissue was analyzed from 23 LGSC, 71 serous LMP tumors, and 2 recurrences. At diagnosis, 86% of patients with LMP tumors had stage I disease vs 78% of patients with LGSC had stage III/IV disease. There were 7 (10%) LMP and 13 (56.5%) LGSC recurrences. Median initial PFS was 76 and 37 months and median OS was 88 and 82 months for LMP and LGSC, respectively. Fourteen received endocrine therapy; nine for treatment of recurrent LGSC. Median therapy was 21 months, with 3 complete responses, 2 partial responses and 1 stable disease. All tumors were ER+ (median H-score 210) and 89% were PR+ (median H-score 130). ER H-scores and ESR1 expression levels were not significantly different between LGSC and LMP tumors (p = 0.1942, p = 0.0893). PR H-scores were higher in LMP tumors (p < 0.00001) but PGR expression was not significantly different (p = 0.6581). In the Cox PH analysis, ER H-score was a significant predictor of both PFS and OS (p < 0.001, p = 0.004). The Cox model identified independent sets of gene expression associated with PFS and OS in both the LGSC and LMP cohorts (c-indices 0.679, 0.570, 0.626, 0.689). Conclusions: Endocrine therapy is an active area of interest in the treatment of ovarian neoplasms. ER H-score and gene expression of downstream ER targets could improve upon the use of hormone receptors to determine risk of recurrence and guide use of adjuvant endocrine therapy.

Abstract
ALERT-B provides an effective screening tool for gastroenterological late effects. 84.4% and 95.7% of patients demonstrated complications at 6 and 12 months post-treatment. ROC curves at baseline indicated an AUC of 0.867 compared to the GSRS diarrhoea subscale. ROC curves at baseline indicated an AUC of 0.765 compared to the EPIC bowel subscale.
There is an increasing need to measure treatment-related side effects in normal tissues following cancer therapy. The ALERT-B (Assessment of Late Effects of RadioTherapy - Bowel) questionnaire is a screening tool that is composed of four items related specifically to bowel symptoms. Those patients that respond with a “yes” to any of these items are referred on to gastroenterologist in order to improve the long-term consequences of these side effects of radiological treatment. Here we wish to test the ability of this questionnaire to identify these subsequent gastroenterological complications by tracking prostate cancer patients that were positive with respect to ALERT-B. We also carry out receiver-operator curve (ROC) analysis for baseline data for an overall ALERT-B questionnaire score with respect to subscale data for the Gastrointestinal Symptom Rating Scale (GSRS) and the Expanded Prostate Cancer Index Composite (EPIC-26) questionnaire. 84.4% and 95.7% of patients identified by the ALERT-B questionnaire demonstrated complications diagnosed at 6 and 12 months post-treatment, respectively. ROC curve analysis of baseline data showed that ALERT-B detected clinically relevant levels of side effects established at baseline by the GSRS diarrhoea subscale (AUC = 0.867, 95% CI = 0.795 to 0.926) and at the minimally important level of side effects for the EPIC bowel subscale (AUC = 0.765, 95% CI = 0.617 to 0.913). These results show that ALERT-B provides a simple and effective screening tool for identifying gastroenterological complications after treatment for prostate cancer.

Abstract
The serine/threonine Protein Phosphatase 2A (PP2A) functions as a tumor suppressor by negatively regulating multiple oncogenic signaling pathways. The canonical PP2A holoenzyme comprises a scaffolding subunit (PP2A Aα/β), which serves as the platform for binding of both the catalytic C subunit and one regulatory B subunit. Somatic heterozygous missense mutations in PPP2R1A, the gene encoding the PP2A Aα scaffolding subunit, have been identified across multiple cancer types, but the effects of the most commonly mutated residue, Arg-183, on PP2A function have yet to be fully elucidated. In this study, we used a series of cellular and in vivo models and discovered that the most frequent Aα R183W mutation formed alternative holoenzymes by binding of different PP2A regulatory subunits compared with wild-type Aα, suggesting a rededication of PP2A functions. Unlike wild-type Aα, which suppressed tumorigenesis, the R183W mutant failed to suppress tumor growth in vivo through activation of the MAPK pathway in RAS-mutant transformed cells. Furthermore, cells expressing R183W were less sensitive to MEK inhibitors. Taken together, our results demonstrate that the R183W mutation in PP2A Aα scaffold abrogates the tumor suppressive actions of PP2A, thereby potentiating oncogenic signaling and reducing drug sensitivity of RAS-mutant cells.

Abstract
BACKGROUND Palmar osteochondral disease (POD) is a common cause of lameness in competition horses. Magnetic resonance imaging (MRI) is the most sensitive diagnostic modality currently available, however it may not be financially or logistically practical for routine screening of POD. There is increasing interest in the use of metabolomics for diagnosis prior to progression to irreversible damage. OBJECTIVES To determine metabolite levels in synovial fluid (SF) of horses with a clinical diagnosis of POD based on diagnostic analgesia and MRI, with the hypothesis that metabolomic profiles differ between diseased and healthy joints. STUDY DESIGN Prospective clinical study. METHODS Synovial fluid was collected from metacarpo/tarsophalangeal joints (MC/TPJ) of 29 horses (n = 51 joints), including 14 controls (n = 26) and 15 cases (n = 25), the latter with lameness localised to the MC/TPJ and MR changes consistent with POD (n = 23). Spectra were produced using 1 H-nuclear magnetic resonance (NMR) spectroscopy and analysed. RESULTS Twenty-five metabolites were recognised associated with various biosynthetic and degradation pathways. The metabolite abundances within the controls demonstrated increased variability compared with the clinical group. The low level of variance between the spectra of the two groups was explained by five principal components. Cross-validation of the cohort demonstrated modest separation of predictive power (R2 = 0.67; Q2 = 0.34). Although statistical significance was not achieved, the most influential metabolites were glucose and lactate. MAIN LIMITATIONS The modest sample size and variation in signalment, background and presenting condition of the controls may have impacted the discriminative power of the constructed models. The lack of matched controls, differences in time of fluid collection and freezing times may have also reduced accuracy when representing metabolite profiles. CONCLUSIONS This study identified and quantified metabolites present in MC/TPJ SF of clinical cases with POD.

Abstract
BACKGROUND Recurrent ovarian, fallopian tube, and peritoneal cancers have limited potential for cure with traditional therapies. Preliminary results from a phase I study of everolimus and bevacizumab in advanced solid tumors showed it to be a promising combination. The primary objective of this study was to evaluate the 6-month progression-free survival for everolimus and bevacizumab in recurrent ovarian, peritoneal, and fallopian tube cancer. Secondary objectives included evaluation of efficacy and safety. METHODS In this open-label, single-institution, phase II trial, patients received everolimus 10 mg/day by mouth and bevacizumab 10 mg/kg intravenously every 14 days on a 28-day cycle. Treatment continued until disease progression or adverse event. RESULTS Fifty patients were enrolled. Median age was 60.5 years (range 28-82). Forty-six (92%) subjects had measurable disease. Thirteen (26%) (24% adjusted) were progression-free at 6 months (95% CI 16.67-42.71%). One patient had a complete response, while six had a partial response and 35 had stable disease as their best response. Patients with both platinum-sensitive and -resistant disease demonstrated responses, as did some prior bevacizumab exposure. There were two grade 4 and 31 grade 3 toxicities noted in 25 distinct patients. The most common reported toxicities included oral mucositis, fatigue, diarrhea, hypertension, pain, nausea and anorexia. Thirty-eight (76%) patients came off study because of disease progression. Unique molecular profiles were identified in long-term responders. CONCLUSIONS Combining everolimus and bevacizumab does not distinctly improve response compared to bevacizumab alone, but further study of selected patients with alterations in the PI3K/mTOR pathway may document benefit.

Abstract
As a field we have made tremendous strides in treating breast cancer, with a decline in the past 30 years of overall breast cancer mortality. However, this progress is met with little affect once the disease spreads beyond the primary site. With a 5-year survival rate of 22%, 10-year of 13%, for those patients with metastatic breast cancer (mBC), our ability to effectively treat wide spread disease is minimal. A major contributing factor to this ineffectiveness is the complex make-up, or heterogeneity, of the primary site. Within a primary tumor, secreted factors, malignant and pre-malignant epithelial cells, immune cells, stromal fibroblasts and many others all reside alongside each other creating a dynamic environment contributing to metastasis. Furthermore, heterogeneity contributes to our lack of understanding regarding the cells' remarkable ability to undergo epithelial/non-cancer stem cell (CSC) to mesenchymal/CSC (E-M/CSC) plasticity. The enhanced invasion & motility, tumor-initiating potential, and acquired therapeutic resistance which accompanies E-M/CSC plasticity implicates a significant role in metastasis. While most work trying to understand E-M/CSC plasticity has been done on malignant cells, recent evidence is emerging concerning the ability for pre-malignant cells to undergo E-M/CSC plasticity and contribute to the metastatic process. Here we will discuss the importance of E-M/CSC plasticity within malignant and pre-malignant populations of the tumor. Moreover, we will discuss how one may potentially target these populations, ultimately disrupting the metastatic cascade and increasing patient survival for those with mBC.

Abstract
OBJECTIVE It is important to understand factors that moderate the likelihood of developing suicidal thoughts following traumatic exposure and posttraumatic stress symptoms. METHOD In this cross-sectional study, a moderated atemporal mediation analysis was conducted in a sample of 709 college students (71% female, M age = 19.90 years, 67% Caucasian) to test the associations between trauma, posttraumatic stress disorder (PTSD) symptoms, and suicidal ideation, with grit entered as a moderator of all paths in the equation. RESULTS PTSD symptoms mediated the association between trauma and suicidal ideation. Grit moderated the direct pathway from PTSD symptoms to suicidal ideation. CONCLUSIONS Grit and other constructs of resiliency may inform strength-focused interventions to remediate the impact of trauma and posttraumatic stress symptoms and potentially reduce suicidal thoughts and risk for suicide.

Abstract
Somatic mutation of the protein phosphatase 2A (PP2A) Aα-subunit gene PPP2R1A is highly prevalent in high-grade endometrial carcinoma. The structural, molecular, and biological basis by which the most recurrent endometrial carcinoma-specific mutation site P179 facilitates features of endometrial carcinoma malignancy has yet to be fully determined. Here, we used a series of structural, biochemical, and biological approaches to investigate the impact of the P179R missense mutation on PP2A function. Enhanced sampling molecular dynamics simulations showed that arginine-to-proline substitution at the P179 residue changes the protein's stable conformation profile. A crystal structure of the tumor-derived PP2A mutant revealed marked changes in A-subunit conformation. Binding to the PP2A catalytic subunit was significantly impaired, disrupting holoenzyme formation and enzymatic activity. Cancer cells were dependent on PP2A disruption for sustained tumorigenic potential, and restoration of wild-type Aα in a patient-derived P179R-mutant cell line restored enzyme function and significantly attenuated tumorigenesis and metastasis in vivo. Furthermore, small molecule-mediated therapeutic reactivation of PP2A significantly inhibited tumorigenicity in vivo. These outcomes implicate PP2A functional inactivation as a critical component of high-grade endometrial carcinoma disease pathogenesis. Moreover, they highlight PP2A reactivation as a potential therapeutic strategy for patients who harbor P179R PPP2R1A mutations. SIGNIFICANCE: This study characterizes a highly recurrent, disease-specific PP2A PPP2R1A mutation as a driver of endometrial carcinoma and a target for novel therapeutic development.See related commentary by Haines and Huang, p. 4009.

Abstract
Protein phosphatase 2A (PP2A) represses many oncogenic signaling pathways and is an important tumor suppressor. PP2A comprises three distinct subunits and forms through a highly regulated biogenesis process, with the scaffolding A subunit existing as two highly related isoforms, Aα and Aβ. PP2A's tumor-suppressive functions have been intensely studied, and PP2A inactivation has been shown to be a prerequisite for tumor formation. Interestingly, although partial loss of the Aα isoform is growth promoting, complete Aα loss has no transformative properties. Additionally, in cancer patients, Aα is found to be inactivated in a haploinsufficient manner. Using both cellular and in vivo systems, colorectal and endometrial cancer cell lines, and biochemical and cellular assays, here we examined why the complete loss of Aα does not promote tumorigenesis. CRISPR/Cas9-mediated homozygous Aα deletion resulted in decreased colony formation and tumor growth across multiple cell lines. Protein expression analysis of PP2A family members revealed that the Aα deletion markedly up-regulates Aβ protein expression by increasing Aβ protein stability. Aβ knockdown in control and Aα knockout cell lines indicated that Aβ is necessary for cell survival in the Aα knockout cells. In the setting of Aα deficiency, co-immunoprecipitation analysis revealed increased binding of specific PP2A regulatory subunits to Aβ, and knockdown of these regulatory subunits restored colony-forming ability. Taken together, our results uncover a mechanism by which PP2A Aα regulates Aβ protein stability and activity and suggests why homozygous loss of Aα is rarely seen in cancer patients.

Abstract
INTRODUCTION Intraperitoneal (IP) chemotherapy improves survival in ovarian cancer but its use has been limited by toxicity with cisplatin-based regimens. The primary objective of this study was to define the maximum tolerated dose and dose-limiting toxicity of intravenous (IV) oxaliplatin and IP docetaxel in women with recurrent ovarian, fallopian tube or peritoneal cancer. Secondary objectives were response rate, time to progression, symptom interference with quality of life, and pharmacokinetics. METHODS Patients received a constant dose of oxaliplatin 75 mg/m2 IV on day 1 and docetaxel escalating from 50 mg/m2 IP on day 2 every 3 weeks using a 3 + 3 design. Treatment continued until disease progression, remission, or intolerable toxicity occurred. Plasma and IP samples were taken to determine drug concentrations. Patients completed the MD Anderson Symptom Inventory weekly. RESULTS Twelve patients were included. The median number of cycles was 4 (range 2-6) with a median time to progression of 4.5 months. Among eight patients with measurable disease, the best responses were partial response in two patients, stable disease in five, and progressive disease in one. A total of 14 grade 3-4 toxicities were noted, most commonly hematologic. Four patients, all dose level 3, had six dose-limiting toxicities: two with prolonged neutropenia, one with infection, one with hyponatremia, and two with abdominal pain. Dose level 3 was therefore considered intolerable. The mean±SD ratio of docetaxel area under the curve (AUC) in IP fluid to AUC in plasma was 229±111. Symptom interference with life activities steadily decreased from cycle 1 to 5. CONCLUSIONS Oxaliplatin 75 mg/m2 IV on day 1 and docetaxel 75 mg/m2 IP on day 2 was the maximum tolerated dose. Most patients had partial response or stable disease, even in a heavily pre-treated population. At this dose level, patient-reported outcomes demonstrate temporary but tolerable decrements in quality of life.

Abstract
The serine/threonine phosphatase PP2A regulates a vast portion of the phosphoproteome including pathways involved in apoptosis, proliferation and DNA damage response and PP2A inactivation is a vital step in malignant transformation. Many groups have explored the therapeutic venue of combining PP2A reactivation with kinase inhibition to counteract the very changes in tumor suppressors and oncogenes that lead to cancer development. Conversely, inhibition of PP2A to complement chemotherapy and radiation-induced cancer cell death is also an area of active investigation. Here we review the studies that utilize PP2A targeted agents as combination therapy in cancer. A potential role for PP2A in tumor immunity is also highlighted.
