Abstract
Cyclin-dependent kinase 4/6 inhibitors (CDK4/6i) are widely used in patients with hormone receptor-positive (HR+)/human epidermal growth factor receptor 2 negative (HER2-) advanced/metastatic breast cancer (ABC/MBC) in first line (1L), but little is known about their real-world use and clinical outcomes long-term, in Canada. This study used Pentavere's previously validated artificial intelligence (AI) to extract real-world data on the treatment patterns and outcomes of patients receiving CDK4/6i+endocrine therapy (ET) for HR+/HER2- ABC/MBC at Sinai Health in Toronto, Canada. Between 1 January 2016 and 1 July 2021, 48 patients were diagnosed with HR+/HER2- ABC/MBC and received CDK4/6i + ET. A total of 38 out of 48 patients received CDK4/6i + ET in 1L, of which 34 of the 38 (89.5%) received palbociclib + ET. In 2L, 12 of the 21 (57.1%) patients received CDK4/6i + ET, of which 58.3% received abemaciclib. In 3L, most patients received chemotherapy (10/12, 83.3%). For the patients receiving CDK4/6i in 1L, the median (95% CI) time to the next treatment was 42.3 (41.2, NA) months. The median (95% CI) time to chemotherapy was 46.5 (41.4, NA) months. The two-year overall survival (95% CI) was 97.4% (92.4, 100.0), and the median (range) follow-up was 28.7 (3.4-67.6) months. Despite the limitations inherent in real-world studies and a limited number of patients, these AI-extracted data complement previous studies, demonstrating the effectiveness of CDK4/6i + ET in the Canadian real-world 1L, with most patients receiving palbociclib as CDK4/6i in 1L.

Abstract
Real-world evidence for patients with advanced EGFR-mutated non-small cell lung cancer (NSCLC) in Canada is limited. This study's objective was to use previously validated DARWENTM artificial intelligence (AI) to extract data from electronic heath records of patients with non-squamous NSCLC at University Health Network (UHN) to describe EGFR mutation prevalence, treatment patterns, and outcomes. Of 2154 patients with NSCLC, 613 had advanced disease. Of these, 136 (22%) had common sensitizing EGFR mutations (cEGFRm; ex19del, L858R), 8 (1%) had exon 20 insertions (ex20ins), and 338 (55%) had EGFR wild type. One-year overall survival (OS) (95% CI) for patients with cEGFRm, ex20ins, and EGFR wild type tumours was 88% (83, 94), 100% (100, 100), and 59% (53, 65), respectively. In total, 38% patients with ex20ins received experimental ex20ins targeting treatment as their first-line therapy. A total of 57 patients (36%) with cEGFRm received osimertinib as their first-line treatment, and 61 (39%) received it as their second-line treatment. One-year OS (95% CI) following the discontinuation of osimertinib was 35% (17, 75) post-first-line and 20% (9, 44) post-second-line. In this real-world AI-generated dataset, survival post-osimertinib was poor in patients with cEGFR mutations. Patients with ex20ins in this cohort had improved outcomes, possibly due to ex20ins targeting treatment, highlighting the need for more effective treatments for patients with advanced EGFRm NSCLC.

Abstract
Background Stereotactic radiosurgery (SRS) has supplanted whole brain radiotherapy (WBRT) as standard-of-care adjuvant treatment following surgery for brain metastasis (BrM). Concomitant with the adoption of adjuvant SRS, a new pattern of failure termed "Pachymeningeal failure" (PMF) has emerged. Methods We reviewed a prospective registry of 264 BrM patients; 145 and 119 were treated adjuvantly with WBRT and SRS, respectively. The Cox proportional hazards model was used to identify variables correlating to outcomes. Outcomes were calculated using the cumulative incidence (CI) method. Univariate (UVA) and multivariate analyses (MVA) were done to identify factors associated with PMF. Results CI of PMF was 2 % and 18 % at 12 months, and 2 % and 23 % at 24 months for WRBT and SRS, respectively (p < 0.001). The CI of classic leptomeningeal disease (LMD) was 3 % and 4 % at 12 months, and 6 % and 6 % at 24 months for WBRT and SRS, respectively (P = 0.67). On UVA, adjuvant SRS [HR 9.75 (3.43-27.68) (P < 0.001)]; preoperative dural contact (PDC) [HR 6.78 (1.64-28.10) (P = 0.008)]; GPA score [HR 1.64 (1.11-2.42) (P = 0.012)]; and lung EGFR/ALK status [HR 3.11 (1.02-9.45) (P = 0.045)]; were associated with PMF risk. On MVA, adjuvant SRS [HR 8.15 (2.69-24.7) (P < 0.001)]; and PDC [HR 6.28 (1.51-26.1) (P = 0.012)] remained associated with PMF. Conclusions Preoperative dural contact and adjuvant SRS instead of adjuvant WBRT were associated with an increased risk of PMF. Strategies to improve pachymeningeal radiation coverage to sterilize at risk pachymeninges should be investigated.

Abstract
Peritoneal metastases (PM) are common in metastatic colorectal cancer (mCRC). We aimed to characterize patients with mCRC and PM from a clinical and molecular perspective using the American Association of Cancer Research Genomics Evidence Neoplasia Information Exchange (GENIE) Biopharma Collaborative (BPC) registry. Patients' tumor samples underwent targeted next-generation sequencing. Clinical characteristics and treatment outcomes were collected retrospectively. Overall survival (OS) from advanced disease and progression-free survival (PFS) from start of cancer-directed drug regimen were estimated and adjusted for the left truncation bias. A total of 1,281 patients were analyzed, 244 (19%) had PM at time of advanced disease. PM were associated with female sex [OR: 1.67; 95% confidence interval (CI): 1.11-2.54; P = 0.014] and higher histologic grade (OR: 1.72; 95% CI: 1.08-2.71; P = 0.022), while rectal primary tumors were less frequent in patients with PM (OR: 0.51; 95% CI: 0.29-0.88; P < 0.001). APC occurred less frequently in patients with PM (N = 151, 64% vs. N = 788, 79%) while MED12 alterations occurred more frequently in patients with PM (N = 20, 10% vs. N = 32, 4%); differences in MED12 were not significant when restricting to oncogenic and likely oncogenic variants according to OncoKB. Patients with PM had worse OS (HR: 1.45; 95% CI: 1.16-1.81) after adjustment for independently significant clinical and genomic predictors. PFS from initiation of first-line treatment did not differ by presence of PM. In conclusion, PM were more frequent in females and right-sided primary tumors. Differences in frequencies of MED12 and APC alterations were identified between patients with and without PM. PM were associated with shorter OS but not with PFS from first-line treatment. SIGNIFICANCE Utilizing the GENIE BPC registry, this study found that PM in patients with colorectal cancer occur more frequently in females and right-sided primary tumors and are associated with worse OS. In addition, we found a lower frequency of APC alterations and a higher frequency in MED12 alterations in patients with PM.

Abstract
PURPOSE/OBJECTIVE(S) To report long-term oncologic outcomes among patients with human papillomavirus (HPV)-associated oropharyngeal squamous cell carcinoma (OPSCC) treated with definitive de-intensified chemoradiotherapy. MATERIALS/METHODS Major criteria for de-intensification were (1) AJCC 7th edition T0-T3, N0-N2c, M0 (AJCC 8th edition T0-T3, N0-N2, M0), (2) pathologically confirmed p16 positive, and (3) no or minimal/remote smoking history (non-mutated p53 if ≥30 pack-years). Treatment was 60 Gy intensity-modulated radiotherapy with first-choice concurrent cisplatin 30 mg/m2 once per week (alternative regimens permissible for cisplatin ineligible patients). Patients with T0-T2 N0-1 (AJCC 7th edition) were recommended 60 Gy radiation alone. Systemic therapy received included: cisplatin 30 mg/m2 (n = 122), cetuximab (n = 15), cisplatin 40 mg/m2 (n = 12), carboplatin/paclitaxel (n = 2), and radiation alone (n = 25). Kaplan Meier estimates for overall survival (OS), progression-free survival (PFS), locoregional control (LRC), and freedom from distant metastasis (FFDM) were calculated. Cox regression models were used for comparisons among subgroups. RESULTS A total 176 patients received de-intensified treatment (n = 153 prospective protocol, n = 23 off-protocol). Median follow-up was 52.6 months (range 5.3 - 102.0, 90.8% with minimum 2-year follow-up); 56.8% (n = 100) were never smokers and 43.2% (n = 76) former smokers; former smokers had median 9 pack-years smoking history (range 0.25 - 50) with 46% ≥10 pack-years. Outcomes were as follows: 2-year OS 99.4% and 5-year OS 91.8%; 2-year PFS 94.1% and 5-year PFS 84.3%; 2-year LRC 98.3% and 5-year LRC 95.8%; 2-year FFDM 95.8% and 5-year FFDM 93.2%. Median time to progression events were 21.1 months (range, 7.2 - 54.1) with 37.5% (6 of 16) of recurrences occurring after 24 months. Six total locoregional events occurred (five recurrences and one site of persistent disease), within the 60 Gy planning target volume. Twenty-three patients with T0-T2 N0-1 disease received radiation alone with 2-year PFS 92.9% (5-year 83.8%) and 2-year LRC 100% (5-year 95.2%). Outcomes for former smokers with ≥10 pack-years were comparable to patients with less or no smoking history (2-year PFS 94.1% vs 94.1%; 5-year PFS 90.6% vs 82.7%; HR 0.58, p = 0.38). Early results suggest similar oncologic outcomes among those treated off-protocol (median follow-up 25.6 months) with 1 of 23 patients experiencing locoregional recurrence. CONCLUSION Dose de-intensification of 60 Gy radiotherapy with weekly cisplatin results in favorable long-term tumor control in patients with HPV-associated OPSCC. De-intensified 60 Gy alone may be efficacious in carefully selected patients with T0-T2 N0-1 (AJCC 7th edition) disease. Inclusion of biologically favorable patients with more extensive former smoking history in de-intensification clinical trials may be warranted.

Abstract
PURPOSE/OBJECTIVE(S) The relationship between body composition (BC) and cancer outcomes is complex and incompletely understood. Previous research in non-small cell lung cancer (NSCLC) has been limited to small single-institution studies, which have yielded inconsistent results. MATERIALS/METHODS We conducted a comprehensive multicohort analysis to evaluate the impact of BC on overall survival (OS) in advanced NSCLC treated with systemic therapy. The analysis included data from the phase I/II CP1108 study (NSCLC Durvalumab cohort) and the chemotherapy arm of the phase III MYSTIC trial. We also analyzed data from Dana-Farber Cancer Institute (DFCI) cohorts receiving immunotherapy alone or in combination with chemotherapy. Baseline and follow-up (FU) CT scans were collected and analyzed using deep neural networks for automatic L3 slice selection and body compartment segmentation (skeletal muscle [SM], subcutaneous adipose tissue [SAT], and visceral adipose tissue [VAT]). We compared OS based on baseline BC measures or their change at the first FU scan. The impact of sarcopenia at baseline was evaluated in association with the delta metrics. RESULTS A total of 1865 NSCLC patients were analyzed, of which 222 were treated on CP1108, 257 were treated on MYSTIC, 870 received IO monotherapy at DFCI (DFCI-IO), and 516 received chemoimmunotherapy at DFCI (DFCI-CIO). The median ages were 65, 63, 66, and 65, respectively. A loss in SM mass >5%, as indicated by a change in L3 SM area, was significantly associated with poorer OS across all patient groups (median [months]: 5 vs. 19; p<0.001 for CP1108, 11 vs. 14; p = 0.03 for MYSTIC, 11 vs. 17; p<0.001 for DFCI-IO, and 12 vs. 22; p<0.001 for DFCI-CIO). This effect was driven by male patients, with a non-significant association (p>0.5) among female patients in the MYSTIC and DFCI-CIO cohorts. An increase in SAT density >5%, as quantified by the average CT attenuation in HU of the SAT compartment, was significantly linked to poorer OS in three patient groups (median [months]: 4 vs. 19; p<0.001 for CP1108, 10 vs. 17; p<0.001 for DFCI-IO, and 12 vs. 20; p = 0.003 for DFCI-CIO). This was primarily observed among female patients, with a non-significant association (p>0.5) among male patients in the DFCI-CIO cohort. On subgroup analysis, loss in SM mass had an impact on OS in patients with baseline sarcopenia (median [months] 5 vs. 22; p<0.001 for CP1108, 5 vs. 12; p = 0.03 for MYSTIC, 11 vs. 17; p<0.001 for DFCI IO, and 9 vs. 17; p = 0.003 for DFCI-CIO). Conversely, no association was observed between change in SM mass and OS in patients without sarcopenia at baseline in the MYSTIC and DFCI-IO cohorts. CONCLUSION Sarcopenia and loss in SM mass during systemic therapy for NSCLC are markers of poor outcome, especially in male patients. SAT density changes are also strongly associated with prognosis, particularly in female patients. Automated CT-derived BC measurements should be considered along with other risk factors in determining lung cancer prognosis and ability to tolerate oncologic treatments.

Abstract
Introduction NSCLC with MET exon 14 skipping mutation (METex14) is associated with poor outcomes. Integration of novel targeted therapies is challenging because of barriers in testing and drug access. We, therefore, sought to characterize the treatment patterns, outcomes, and emerging issues of treatment sequencing in patients with METex14-mutant NSCLC. Methods We reviewed all NSCLC cases with METex14 alterations between 2014 and 2020 across four Canadian cancer centers. Demographics, disease characteristics, systemic therapy, overall response rates (ORRs), survival, and toxicity were summarized. Results Among 64 patients with METex14-mutant NSCLC, the median overall survival was 23.1 months: 127.0 months in stage 1, 27.3 months in resected stage 2 and 3, and 16.6 months in unresectable stage 3 or 4 disease, respectively. In patients with advanced disease, 22% were too unwell for systemic treatment. MET tyrosine kinase inhibitors (TKIs) were administered to 28 patients with an ORR of 33%, median progression-free survival of 2.7 months, and 3.8 months for selective TKIs. Programmed cell death protein-1 (PD-1) inhibitors were given to 25 patients-the ORR was 44% and progression-free survival was 10.6 months. No responses were seen with subsequent MET TKIs after initial TKI treatment. Grade 3 or higher toxicities occurred in 64% of patients who received MET TKI after PD-1 inhibitors versus 8% in those who did not receive PD-1 inhibitors. Conclusions Many patients with advanced METex14 NSCLC were too unwell to receive treatment. PD-1 inhibitors seem effective as an initial treatment, although greater toxicity was seen with subsequent MET TKIs. Thus, timely testing for METex14 skipping and initial therapy are imperative to improving patient survival.

Abstract
Background The role for radiotherapy or surgery in the upfront management of brain metastases (BrM) in epidermal growth factor receptor mutant (EGFRm) or anaplastic lymphoma kinase translocation positive (ALK+) non-small cell lung cancer (NSCLC) is uncertain because of a lack of prospective evidence supporting tyrosine kinase inhibitor (TKI) monotherapy. Further understanding of practice heterogeneity is necessary to guide collaborative efforts in establishing guideline recommendations. Methods We conducted an international survey among medical (MO), clinical (CO), and radiation oncologists (RO), as well as neurosurgeons (NS), of treatment recommendations for asymptomatic BrM (in non-eloquent regions) EGFRm or ALK+ NSCLC patients according to specific clinical scenarios. We grouped and compared treatment recommendations according to specialty. Responses were summarized using counts and percentages and analyzed using the Fisher exact test. Results A total of 449 surveys were included in the final analysis: 48 CO, 85 MO, 60 NS, and 256 RO. MO and CO were significantly more likely than RO and NS to recommend first-line TKI monotherapy, regardless of the number and/or size of asymptomatic BrM (in non-eloquent regions). Radiotherapy in addition to TKI as first-line management was preferred by all specialties for patients with ≥4 BrM. NS recommended surgical resection more often than other specialties for BrM measuring >2 cm. Conclusions Recommendations for the management of BrM from EGFRm or ALK+ NSCLC vary significantly according to oncology sub-specialties. Development of multidisciplinary guidelines and further research on establishing optimal treatment strategies is warranted.

Abstract
OBJECTIVE The goal was to characterize short-term kidney status and describe variation in early care utilization in a multicenter cohort of patients with childhood-onset systemic lupus erythematosus (cSLE) and nephritis. METHODS We analyzed previously collected prospective data from North American patients with cSLE with kidney biopsy-proven nephritis enrolled in the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Registry from March 2017 through December 2019. We determined the proportion of patients with abnormal kidney status at the most recent registry visit and applied generalized linear mixed models to identify associated factors. We also calculated frequency of medication use, both during induction and ever recorded. RESULTS We identified 222 patients with kidney biopsy-proven nephritis, with 64% class III/IV nephritis on initial biopsy. At the most recent registry visit at median (interquartile range) of 17 (8-29) months from initial kidney biopsy, 58 of 106 patients (55%) with available data had abnormal kidney status. This finding was associated with male sex (odds ratio [OR] 3.88, 95% confidence interval [95% CI] 1.21-12.46) and age at cSLE diagnosis (OR 1.23, 95% CI 1.01-1.49). Patients with class IV nephritis were more likely than class III to receive cyclophosphamide and rituximab during induction. There was substantial variation in mycophenolate, cyclophosphamide, and rituximab ever use patterns across rheumatology centers. CONCLUSION In this cohort with predominately class III/IV nephritis, male sex and older age at cSLE diagnosis were associated with abnormal short-term kidney status. We also observed substantial variation in contemporary medication use for pediatric lupus nephritis between pediatric rheumatology centers. Additional studies are needed to better understand the impact of this variation on long-term kidney outcomes.

Abstract
PURPOSE Hypofractionation is noninferior to conventional fractionation in the treatment of localized prostate cancer. Using results from the European Society of Radiation Oncology's (ESTRO) Global Impact of Radiotherapy in Oncology (GIRO) initiative survey on hypofractionation, this study identifies rates of adoption, facilitating factors, and barriers to adoption of hypofractionation in prostate cancer across World Bank income groups. MATERIALS AND METHODS The ESTRO-GIRO initiative administered an international, anonymous, electronic survey to radiation oncologists from 2018 to 2019. Physician demographics, clinical practice characteristics, and hypofractionation regimen use (if any) for several prostate cancer scenarios were collected. Responders were asked about specific justifications and barriers to adopting hypofractionation, and responses were stratified by World Bank income group. Multivariate logistic regression models were used to analyze variables associated with hypofractionation preference. RESULTS A total of 1,157 physician responses were included. Most respondents (60%) were from high-income countries (HICs). In the curative setting, hypofractionation was most often preferred in low- and intermediate-risk prostate cancers, with 52% and 47% of respondents reporting hypofractionation use in ≥50% of patients, respectively. These rates drop to 35% and 20% in high-risk prostate cancer and where pelvic irradiation is indicated. Most respondents (89%) preferred hypofractionation in the palliative setting. Overall, respondents from upper-middle-income countries and lower-middle- and low-income countries were significantly less likely to prefer hypofractionation than those from HICs (P < .001). The most frequently cited justification and barrier were availability of published evidence and fear of worse late toxicity, respectively. CONCLUSION Hypofractionation preference varies by indication and World Bank income group, with greater acceptance among providers in HICs for all indications. These results provide a basis for targeted interventions to increase provider acceptance of this treatment modality.

Abstract
Breastfeeding is often considered principally a biological issue but success is impacted by the socio-ecological environment of the lactating parent. Identifying current attitudes towards breastfeeding is essential in the effort toward normalizing breastfeeding in communities, including university campuses. The study explored campus community knowledge, awareness, and attitudes about breastfeeding, including available resources and applicable laws on two university campuses in the southern United States. This cross-sectional, self-reporting study utilized the Iowa Infant Feeding Attitude Scale and an adaptation of the Breastfeeding Behavior Questionnaire to survey a convenience sample. Results revealed decreased awareness of protective laws, availability of private lactation space, and insufficient public appreciation of breastfeeding's unique advantages to both lactating parent and infant as barriers to breastfeeding. These findings will help develop additional breastfeeding strategies to improve university campus community breastfeeding initiatives.

Abstract
PURPOSE To retrospectively review the clinical outcomes of patients with metastatic breast cancer (MBCa) following liver directed ablative intent radiotherapy (RT). METHODS Demographics, disease and treatment characteristics of patients with MBCa who received liver metastasis (LM) directed ablative RT between 2004-2020 were analysed. The primary outcome was local control (LC), secondary outcomes included overall survival (OS) and progression-free survival (PFS) analyzed by univariate (UVA) and multi-variable analysis (MVA). RESULTS Thirty MBCa patients with 50 LM treated with 5-10 fraction RT were identified. Median follow-up was 14.6 (range 0.9-156.2) months. Class of metastatic disease was described as induced (12 patients, 40%), repeat (15 patients, 50%) and de novo (three patients, 10%). Median size of treated LM was 3.1 cm (range 1-8.8 cm) and median biologically effective dose delivered was 122 (Q1-Q3; 98-174) Gy3. One-year LC rate was 100%. One year and two-year survival was 89% and 63%, respectively, with size of treated LM predictive of OS (HR 1.35, p = 0.023) on UVA. Patients with induced OMD had a significantly higher rate of progression (HR 4.77, p = 0.01) on UVA, trending to significance on MVA (HR 3.23, p = 0.051). CONCLUSIONS Hypo-fractionated ablative liver RT in patients with MBCa provides safe, tolerable treatment with excellent LC.

Abstract
BACKGROUND Patients with recurrent or metastatic head and neck squamous cell carcinoma (R/M HNSCC) have a poor prognosis. The phase III KESTREL study evaluated the efficacy of durvalumab [programmed death-ligand 1 (PD-L1) antibody] with or without tremelimumab [cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) antibody], versus the EXTREME regimen in patients with R/M HNSCC. PATIENTS AND METHODS Patients with HNSCC who had not received prior systemic treatment for R/M disease were randomized (2 : 1 : 1) to receive durvalumab 1500 mg every 4 weeks (Q4W) plus tremelimumab 75 mg Q4W (up to four doses), durvalumab monotherapy 1500 mg Q4W, or the EXTREME regimen (platinum, 5-fluorouracil, and cetuximab) until disease progression. Durvalumab efficacy, with or without tremelimumab, versus the EXTREME regimen in patients with PD-L1-high tumors and in all randomized patients was assessed. Safety was also assessed. RESULTS Durvalumab and durvalumab plus tremelimumab were not superior to EXTREME for overall survival (OS) in patients with PD-L1-high expression [median, 10.9 and 11.2 versus 10.9 months, respectively; hazard ratio (HR) = 0.96; 95% confidence interval (CI) 0.69-1.32; P = 0.787 and HR = 1.05; 95% CI 0.80-1.39, respectively]. Durvalumab and durvalumab plus tremelimumab prolonged duration of response versus EXTREME (49.3% and 48.1% versus 9.8% of patients remaining in response at 12 months), correlating with long-term OS for responding patients; however, median progression-free survival was longer with EXTREME (2.8 and 2.8 versus 5.4 months). Exploratory analyses suggested that subsequent immunotherapy use by 24.3% of patients in the EXTREME regimen arm contributed to the similar OS outcomes between arms. Grade 3/4 treatment-related adverse events (TRAEs) for durvalumab, durvalumab plus tremelimumab, and EXTREME were 8.9%, 19.1%, and 53.1%, respectively. CONCLUSIONS In patients with PD-L1-high expression, OS was comparable between durvalumab and the EXTREME regimen. Durvalumab alone, and with tremelimumab, demonstrated durable responses and reduced TRAEs versus the EXTREME regimen in R/M HNSCC.

Abstract
The ability of a patient tumor to engraft an immunodeficient mouse is the strongest known independent indicator of poor prognosis in early-stage non-small cell lung cancer (NSCLC). Analysis of primary NSCLC proteomes revealed low-level expression of mitochondrial aconitase (ACO2) in the more aggressive, engrafting tumors. Knockdown of ACO2 protein expression transformed immortalized lung epithelial cells, whereas upregulation of ACO2 in transformed NSCLC cells inhibited cell proliferation in vitro and tumor growth in vivo. High level ACO2 increased iron response element binding protein 1 (IRP1) and the intracellular labile iron pool. Impaired cellular proliferation associated with high level ACO2 was reversed by treatment of cells with an iron chelator, whereas increased cell proliferation associated with low level ACO2 was suppressed by treatment of cells with iron. Expression of CDGSH iron-sulfur (FeS) domain-containing protein 1 [CISD1; also known as mitoNEET (mNT)] was modulated by ACO2 expression level and inhibition of mNT by RNA interference or by treatment of cells with pioglitazone also increased iron and cell death. Hence, ACO2 is identified as a regulator of iron homeostasis and mNT is implicated as a target in aggressive NSCLC. IMPLICATIONS FeS cluster-associated proteins including ACO2, mNT (encoded by CISD1), and IRP1 (encoded by ACO1) are part of an "ACO2-Iron Axis" that regulates iron homeostasis and is a determinant of a particularly aggressive subset of NSCLC.

Abstract
PURPOSE Hypofractionated breast radiotherapy has been found to be equivalent to conventional fractionation in many clinical trials. Using data from the European Society for Radiotherapy and Oncology Global Impact of Radiotherapy in Oncology survey, we identified preferences for hypofractionation in breast cancer across World Bank income groups and the perceived facilitators and barriers to its use. MATERIALS AND METHODS An international, electronic survey was administered to radiation oncologists from 2018 to 2019. Demographics, practice characteristics, preferred hypofractionation regimen for specific breast cancer scenarios, and facilitators and barriers to hypofractionation were reported and stratified by World Bank income groups. Variables associated with hypofractionation were assessed using multivariate logistic regression models. RESULTS One thousand four hundred thirty-four physicians responded: 890 (62%) from high-income countries (HICs), 361 (25%) from upper-middle-income countries (UMICs), 183 (13%) from low- and lower-middle-income countries (LLMICs). Hypofractionation was preferred most frequently in node-negative disease after breast-conserving surgery, with the strongest preference reported in HICs (78% from HICs, 54% from UMICs, and 51% from LLMICs, P < .001). Hypofractionation for node-positive disease postmastectomy was more frequently preferred in LLMICs (28% from HICs, 15% from UMICs, and 35% from LLMICs, P < .001). Curative doses of 2.1 to < 2.5 Gy in 15-16 fractions were most frequently reported, with limited preference for ultra-hypofractionation, but significant variability in palliative dosing. In adjusted analyses, UMICs were significantly less likely than LLMICs to prefer hypofractionation across all curative clinical scenarios, whereas respondents with > 1 million population catchments and with intensity-modulated radiotherapy were more likely to prefer hypofractionation. The most frequently cited facilitators and barriers were published evidence and fear of late toxicity, respectively. CONCLUSION Preference for hypofractionation varied for curative indications, with greater acceptance in earlier-stage disease in HICs and in later-stage disease in LLMICs. Targeted educational interventions and greater inclusivity in radiation oncology clinical trials may support greater uptake.

Abstract
BACKGROUND Due to the aging population, the number of older patients diagnosed with pancreatic ductal adenocarcinoma (PDAC) will continue to rise. STUDY DESIGN Utilizing the NCDB from 2010 to 2016, patients with early stage, clinically node negative PDAC who were ≥70 years old and had a Whipple were identified. Multivariable logistic regressions were used to determine independent factors for R0 resection and NAT. Cox-proportional-hazards regression analyses examined for the impact of NAT on the risk of death. RESULTS Of 5086 patients, 51.7% received upfront surgery + adjuvant therapy (UFS + AT), followed by 29.9% UFS only, and the remainder NAT. NAT significantly improved OS compared to a combined cohort of those that had UFS ± AT. NAT retained its independent survival benefit when compared to only patients that had UFS + AT. CONCLUSION For older patients diagnosed with early stage PDAC, NAT was associated with improved R0 resection rates and a significant survival benefit when compared to the current standard of care.

Abstract
PURPOSE Working parents, and a rising number of adults delivering care for aging relatives, experience numerous challenges in their personal, family, professional, and financial lives owing to multiple responsibilities. This study describes the experiences of Canadian radiation oncologist (RO) parents and family caregivers, reporting challenges that may exist in providing family care with clinical and academic work commitments. METHODS AND MATERIALS Canadian ROs, via RO heads of departments in cancer centers across Canada, and physician members of the Canadian Association of Radiation Oncology were invited to participate in an anonymous online survey between November 2021 and January 2022. The survey focused on demographics, experiences of pregnancy and leave, parenting and adult caregiving responsibilities, and self-care. RESULTS A total of 103 staff ROs (38%) completed the survey and 78 (75.7%) identified as having a parental (76 [89.7%]) and/or other family caregiver (8 [10.3%]) role; 41% were female and 59% were male, with no difference between genders in the number of children (median, 2; interquartile range, 1-3; P = .17). More female respondents took parental leave for their first child compared with male respondents (mean, 29 vs 6 weeks; P < .001). Of male respondents who started caring for their first child during residency, 27% took parental leave, compared with 77% who started caring for their first child as a staff member (P = .003). The majority of respondents described "always/usually" having collegial support for each pregnancy and parental leave. Both genders described parental responsibilities as negatively affecting attendance at conferences (male, 65%; female, 77%; P = .31) and early or late work-related meetings (male, 76%; female, 79%; P = 1.0). More female respondents described parental responsibilities as negatively affecting their career (50% vs 29%; P = .085). Of female respondents, 52% (vs 26% of male respondents; P = .044) identified a physician mentor or positive role model around parenting issues. CONCLUSIONS Parental and other family caregiving responsibilities are not gender unique in Canadian ROs, but competing work and family roles may affect genders differently.

Abstract
The lesbian, gay, bisexual, transgender, queer/questioning and two-spirited, plus (LGBTQ2 +) community experiences cancer-related health disparities and inequities. Our objective was to assess LGBTQ2 + knowledge, attitudes, practices and education interest of healthcare professionals (HCPs), identify opportunities to improve care and inform the development of an HCP education curriculum. This was a mixed methods quality improvement study conducted within a tertiary academic cancer centre. An email was sent to all gynaecologic oncology disease site staff (n = 92) with a secure link to an online survey. We measured respondents' sociodemographic characteristics and LGBTQ2 + knowledge, attitudes, practice behaviours and education interest. Open comments explored HCP experiences and reservations caring for LGBTQ2 + patients and suggestions to improve care. Seventy-five out of ninety-two (82%) HCPs completed the survey, with 7% identifying as LGBTQ2 + . HCPs reported feeling less comfortable (88% vs. 80%, p = 0.031) and knowledgeable (44% vs. 27%, p < 0.001) caring for transgender patients compared to LGBQ2 + patients. Most (76%) were unaware whether LGBTQ2 + -specific patient educational materials existed within their institution. Almost all (92% strongly agreed/agreed) were interested in receiving LGBTQ2 + -specific education. Two themes emerged from analysis of open comments: (i) HCPs are concerned of offending LGBTQ2 + individuals because of their lack of knowledge and (ii) HCPs desire LGBTQ2 + -specific health training, specifically in asking pronouns and caring for transgender patients. HCPs report competency gaps in caring for LGBTQ2 + patients with cancer but desire education. In response, we recommend institutions develop an educational curriculum for HCPs improve communication and inclusivity in cancer care.

Abstract
BACKGROUND The Multicenter Selective Lymphadenectomy Trial II (MSLT-II) led to a change in the management of tumor-positive sentinel lymph nodes (SLNs) from completion node dissection (CLND) to nodal observation. This study aimed to evaluate prognostic factors for predicting sentinel node basin recurrence (SNBR) using data from MSLT-II trial participants. METHODS In MSLT-II, 1076 patients were treated with observation. Patients were included in the current study if they had undergone a post-sentinel node basin ultrasound (PSNB-US) within 4 months after surgery. The study excluded patients with positive SLN by reverse transcription-polymerase chain reaction (RT-PCR) or incomplete SLN pathologic data. Primary tumor, patient, PSNB-US, and SLN characteristics were evaluated. Multivariable regression analyses were performed to determine independent prognostic factors associated with SNBR. RESULTS The study enrolled 737 patients: 193 (26.2%) patients with SNBR and 73 (9.9%) patients with first abnormal US. The patients with an abnormal first US were more likely to experience SNBR (23.8 vs. 5.0%). In the multivariable analyses, increased risk of SNBR was associated with male gender (adjusted hazard ratio [aHR], 1.38; 95% confidence interval [CI], 1.00-1.9; p = 0.049), increasing Breslow thickness (aHR, 1.10; 95% CI, 1.01-1.2; p = 0.038), presence of ulceration (aHR, 1.93; 95% CI, 1.42-2.6; p < 0.001), sentinel node tumor burden greater than 1 mm (aHR, 1.91; 95% CI, 1.10-3.3; p = 0.022), lymphovascular invasion (aHR, 1.53; 95% CI, 1.00-2.3; p = 0.048), and presence of abnormal PSNB-US (aHR, 4.29; 95% CI, 3.02-6.1; p < 0.001). CONCLUSIONS The first postoperative US together with clinical and pathologic factors may play an important role in predicting SNBR.

Abstract
BACKGROUND Children with juvenile idiopathic arthritis (JIA) who achieve a drug free remission often experience a flare of their disease requiring either intraarticular steroids (IAS) or systemic treatment with disease modifying anti-rheumatic drugs (DMARDs). IAS offer an opportunity to recapture disease control and avoid exposure to side effects from systemic immunosuppression. We examined a cohort of patients treated with IAS after drug free remission and report the probability of restarting systemic treatment within 12 months. METHODS We analyzed a cohort of patients from the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Registry who received IAS for a flare after a period of drug free remission. Historical factors and clinical characteristics and of the patients including data obtained at the time of treatment were analyzed. RESULTS We identified 46 patients who met the inclusion criteria. Of those with follow up data available 49% had restarted systemic treatment 6 months after IAS injection and 70% had restarted systemic treatment at 12 months. The proportion of patients with prior use of a biologic DMARD was the only factor that differed between patients who restarted systemic treatment those who did not, both at 6 months (79% vs 35%, p < 0.01) and 12 months (81% vs 33%, p < 0.05). CONCLUSION While IAS are an option for all patients who flare after drug free remission, it may not prevent the need to restart systemic treatment. Prior use of a biologic DMARD may predict lack of success for IAS. Those who previously received methotrexate only, on the other hand, are excellent candidates for IAS.

Abstract
ABSTRACT Biofilm formation of Listeria monocytogenes on stainless steel, a widely used abiotic surface in the food processing industry, was investigated by focusing on the attachment tendency and behavior of L. monocytogenes 08-5578 on eight different stainless steel surfaces: glass bead blasted (rough and fine), deburred (Timesaver), drum deburred, pickled, pickled and drum polished, electrolytic polished, and cold rolled (untreated control). The aim was to see whether there are finishes with significantly lower bacterial attachment. Surface roughness data (measured via four roughness parameters), determined by interferometry, was also compared with the number of adhering cells to detect possible correlations. Cultivation of L. monocytogenes biofilms was carried out using a CDC biofilm reactor with 1% tryptic soy broth set at 20°C for 4, 8, and 24 h. In addition, a cultivation trial was run with continuous nutrient flow (1% tryptic soy broth, 6.2 mL/min) for 24 h. Eight-hour results showed a significant difference (P < 0.05) in biofilm cell counts in biofilms between the glass bead-blasted surfaces (3.23 and 3.26 log CFU/cm2 for the fine and rough, respectively) and deburred (Timesaver) surface (2.57 log CFU/cm2), between drum deburred and deburred (Timesaver) surface (3.41 versus 2.57 log CFU/cm2), and between drum deburred and pickled surface (3.41 versus 2.77 log CFU/cm2). Data gained after 4-h, 24-h, and 24-h plus an additional 24-h continuous flow cultivation showed no significant difference in attachment among surfaces. No correlation between roughness data and attachment was found after all four incubation times, suggesting that roughness values, at these ranges, are insufficient in determining the surfaces' affinity to bacteria. Overall, this study suggests that roughness values cannot be used to predict the degree of L. monocytogenes attachment to a specific stainless steel surface. HIGHLIGHTS

Abstract
Importance The number of older patients (80 years and older) diagnosed with locally advanced rectal cancer (LARC) is expected to increase. Although current guidelines recommend neoadjuvant chemoradiation therapy (NACRT) followed by resection, little is known about management and outcomes in this older population. Objective To assess the trends in management of older patients diagnosed with LARC who had a surgical resection. Design, Setting, and Participants Patients 80 years and older who had a surgical resection for LARC were identified in the 2004-2016 National Cancer Database. Patients were grouped based on therapy sequence: (1) surgery followed by adjuvant therapy (AT), ie, chemotherapy or radiation; (2) surgery alone; or (3) NACRT followed by surgical resection. Data were analyzed in May 2021. Exposures NACRT followed by surgery, and surgery with or without AT. Main Outcomes and Measures Overall survival (OS) was assessed using Kaplan-Meier analyses with inverse probability of treatment weighting (IPTW) and Cox proportional hazards regression were performed to examine the association of NACRT with the risk of death. Results Of 3868 patients with LARC who underwent surgical resection, 2042 (52.8%) were male, and the mean (SD) age was 83.4 (3.0) years. A total of 2273 (58.8%) received NACRT followed by surgical resection. Factors independently associated with NACRT were more recent diagnosis, age 80 to 85 years (vs 86 years and older), fewer comorbidities, larger tumors, and node-positive disease. The Kaplan-Meier analyses with IPTW showed that 3-year and 5-year OS for NACRT (3-year: 68.9%; 95% CI, 67.0-70.8; 5-year: 51.1%; 95% CI, 49.0-53.4) vs surgery with AT (3-year: 64.4%; 95% CI, 59.0-70.2; 5-year: 43.0%; 95% CI, 37.4-49.5) vs surgery alone (3-year: 55.8%; 95% CI, 52.0-60.0; 5-year: 34.7%; 95% CI, 30.8-39.0) was significantly different (P < .001). After adjusting for confounders, patients who received NACRT were more likely to undergo an R0 resection (adjusted odds ratio, 2.16; 95% CI, 1.62-2.88), which independently improved OS (P < .001). Moreover, receipt of NACRT was independently associated with a 25% decreased risk of death (adjusted hazard ratio, 0.75; 95% CI, 0.69-0.82) compared with alternative treatment sequences. Conclusions and Relevance Approximately 40% of older patients with LARC did not receive the current standard of care. In this cohort, NACRT was associated with a higher likelihood of an R0 resection and improved OS. Clinicians should advocate for receipt of NACRT in older patients with LARC.

Abstract
BACKGROUND We aimed to identify factors predicting survival following treatment to large (>4cc) BrM. METHODS From a prospective registry database, we identified 364 adult patients treated for brain metastases (BrM) or surgical cavities larger than >4 cc: 127 and 237 treated with surgery plus stereotactic radiosurgery (S+SRS) and SRS alone, respectively. We compared the 2 treatment arms using propensity score-matched (PSMA) and multivariate analyses (MVA). P values <0.05 were considered statistically significant. RESULTS Median target volume was 6.6cc (4-36.9cc) for intact BrM and 15cc (4-54) for cavities. Median OS was 19 and 12 months for the S+SRS and SRS groups, respectively [HR 1.73 (1.35-2.22) (P<0.001)]. On UVA, number of BrM [HR 1.13 (1.06-1.22) (P<0.001)], ECOG 3-4 [HR 2.78 (1.73-4.46) (P<0.001)], and extracranial disease (ECD) at BrM treatment [HR 1.82 (1.37,2.40) (P<0.001)], correlated inversely with OS. GPA [HR 0.61 (0.52,0.70) (P<0.001)] and receipt of systemic therapy after BrM treatment[HR 0.58 (0.45-0.75) (P<0.001)] correlated to improved OS. On MVA, S+SRS [HR 1.81 (1.19,2.74) (P<0.0054)], reduced target volume [HR 1.03 (1.01,1.06) (P<0.0042)], and receipt of immune/targeted therapy [HR 0.68 (0.50,0.93) (P<0.015)] correlated with OS. PSMA comparing the treatment arms matched by ECD, number of BrM, ECOG, and SRS target volume, demonstrated that treatment arm remained correlated to OS [HR 1.62 (1.20-2.19) (P=0.0015)]. The cumulative incidence (CI) of LF requiring surgical resection at 12 months was 3% versus 7% for S+SRS and SRS groups, respectively [(HR 2.04 (0.89-4.69) (P =0.091)]. CI of PMD at 12 months was 16% versus 0% for S+SRS and SRS groups, respectively. CONCLUSION Reduced SRS target volume, treatment with systemic therapy following BrM treatment, and surgical resection prior to SRS correlate with survival in patients with large BrM. PMSA supports the hypothesis that surgery prior to SRS improves survival in patients with large BrM.

Abstract
OBJECTIVE Neurosurgery (NS) is an essential modality for large brain metastases (BM). As an adjuvant treatment, stereotactic radiosurgery (SRS) reduces neurocognitive toxicity without affecting post-treatment overall survival (OS) compared to whole brain radiation therapy. Pachymeningeal failure (PMF) beyond the SRS field is a relatively newly described entity, distinct from classical leptomeningeal failure (LMF), and unique to postoperative patients treated with adjuvant SRS. We sought to identify risk factors for PMF in patients treated with NS+SRS. METHODS We reviewed a prospective registry (2009 to 2020) and identified all patients treated with NS+SRS. Clinical, radiological, pathological and treatment factors were analyzed. PMF incidence was evaluated using a competing risks model and differences between cohorts were measured using the Fine-Gray method. RESULTS 144 Patients were identified. Median age was 62 (23-90). PMF occurred in 22.2% (32/144) patients). Univariate analysis indicated female gender (HR 2.65, p=0.013), higher GPA status (HR 2.4, p<0.001), absence of prior radiation therapy (HR N/A, p=0.018), controlled extracranial disease (CED) (HR 3.46, p=0.0038), and contact with the pia/dura (HR 3.30, p=0.0053) as risk factors for PMF. Piecemeal (vs En-bloc) resection also trended towards correlation (HR 2.07, p=0.054). Multivariate Analysis identified contact with pia/dura (HR 3.51, p=0.0053), piecemeal resection (HR 2.38, p=0.027), and CED (HR 3.97, p=0.0016) as significant correlates to PMF. PMF correlated with reduced OS (HR 2.90, p<0.001) but was improved compared to patients who developed LMF (HR 10.15, p= p<0.001). CONCLUSIONS PMF is an underrecognized phenomenon that correlates with pre-operative pia/dura contact and piecemeal resection in patients treated with NS+SRS for BM. While less morbid than LMF, it is a critical event that deserves increased vigilance and analysis.

Abstract
Abstract
INTRODUCTION
Approximately 20% of brain metastases (BM) occur in the posterior fossa (PF). However, the criteria to treat large PF BM with surgery (S) followed by stereotactic radiosurgery (SRS) or SRS alone are still unclear. We aim to identify parameters that can help in the decision of treating PF BM with S+SRS or SRS and to compare outcomes between the two groups.
METHODOLOGY
We reviewed a prospective registry database (2009 to 2020) and identified all patients with PF BM (≥4cc in volume) treated with SRS or S+SRS. Clinical and radiological, parameters were analyzed. We examined two endpoints: Overall Survival (OS) and Local Failure (LF).
RESULTS
64 patients were identified; 30 were treated with S+ SRS and 34 with SRS. Gait imbalance and Intracranial pressure symptoms were significantly different between the groups; 97% and 80% for S+SRS vs 47% and 35% for SRS, respectively. Radiologically, there were significant differences in the mean volume of the lesions [6.7 cm3 in SRS vs 29.8cm3 in S+SRS cohort] (p<0.001), compression of the IV ventricle (47% in SRS vs 96% in S+SRS cohort, (p<0.001)) and hydrocephalus (0% in SRS vs 29% in S+SRS cohort, (p<0.001)). One surgical patient required salvage SRS and two SRS patients required salvage S. Patients with S+SRS (HR 0.35, p<0.001) and higher GPA scores (HR 0.62, p=0.007) correlated with better OS. There was no significant difference in rates of LF between the 2 groups.
CONCLUSIONS
Patients treated with S+SRS were more likely to be symptomatic, have larger tumors, and have compression of the IV ventricle with hydrocephalus. Non-symptomatic patients with moderately sized lesions were safely managed with SRS. S+SRS treatment and higher GPA were associated with improved OS.

Abstract
BACKGROUND Testing for tumor programmed death ligand-1 (PD-L1) expression was initially developed with histology specimens in non-small cell lung cancer (NSCLC). However, cytology specimens are widely used for primary diagnosis and biomarker studies in clinical practice. Limited clinical data exist on the predictiveness of cytology-derived PD-L1 scores for response to immune checkpoint inhibitor (ICI) therapy. METHODS We reviewed all NSCLC specimens clinically tested at the University Health Network (UHN) for PD-L1 with 22C3pharmDx, from 01/2013 to 04/2021. Treatment outcomes in patients treated with single agent ICI therapy were reviewed and compared according to cytology- and histology-derived PD-L1 scores. RESULTS We identified 494 and 1942 unique patients with cytology- and histology-derived tumor proportion scores, respectively, during the study period. Informative testing rates were 95 % vs 98 % for cytology and histology, respectively. Clinical data were available for 152 patients treated with single agent ICI: 61 cytology and 91 histology. Overall response rates (ORR) were similar for cytology and histology (36 % vs 34 %; p = 0.23), as well as median progression free survival (PFS) (4.9 vs 4.2 months; p = 0.99) and overall survival (23.4 vs 19.7 months; p = 0.99). The results remained similar even after adjusting for PD-L1 expression levels and line of ICI treatment (PFS HR 1.15; 95 %CI 0.78-1.70; p = 0.47). CONCLUSIONS Treatment outcomes to single agent ICI based on cytology-derived PD-L1 scores were comparable to histology controls. Our results support PD-L1 biomarker testing on both cytology and histology specimens.

Abstract
PURPOSE Small cell lung cancer (SCLC) is an aggressive disease with an overall 5-year survival rate of less than 10%. Treatment for SCLC with cisplatin/etoposide chemotherapy (C/E) ± radiotherapy has changed modestly over several decades. The ubiquitin-proteasome system is an underexplored therapeutic target for SCLC. We preclinically evaluated TAK-243, a first-in-class small molecule E1 inhibitor against UBA1. EXPERIMENTAL DESIGN We assessed TAK-243 in 26 SCLC cell-lines as monotherapy and combined with C/E, the PARP-inhibitor, olaparib, and with radiation using cell viability assays. We interrogated TAK-243 response with gene expression to identify candidate biomarkers. We evaluated TAK-243 alone and in combination with olaparib or radiotherapy with SCLC patient-derived xenografts (PDX). RESULTS Most SCLC cell lines were sensitive to TAK-243 monotherapy (EC50 median 15.8 nmol/L; range 10.2 nmol/L-367.3 nmol/L). TAK-243 sensitivity was associated with gene-sets involving the cell cycle, DNA and chromatin organization, and DNA damage repair, while resistance associated with cellular respiration, translation, and neurodevelopment. These associations were also observed in SCLC PDXs. TAK-243 synergized with C/E and olaparib in vitro across sensitive and resistant SCLC cell lines. Considerable TAK-243-olaparib synergy was observed in an SCLC PDX resistant to both drugs individually. TAK-243 radiosensitization was also observed in an SCLC PDX. CONCLUSIONS TAK-243 displays efficacy in SCLC preclinical models. Enrichment of gene sets is associated with TAK-243 sensitivity and resistance. TAK-243 exhibits synergy when combined with genotoxic therapies in cell lines and PDXs. TAK-243 is a potential therapeutic strategy to improve SCLC patient outcomes, both as a single agent and in combination with existing therapies.

Abstract
Non-small cell lung cancer (NSCLC) is the leading cause of cancer deaths worldwide. Only a fraction of NSCLC harbor actionable driver mutations and there is an urgent need for patient-derived model systems that will enable the development of new targeted therapies. NSCLC and other cancers display profound proteome remodeling compared to normal tissue that is not predicted by DNA or RNA analyses. Here, we generate 137 NSCLC patient-derived xenografts (PDXs) that recapitulate the histology and molecular features of primary NSCLC. Proteome analysis of the PDX models reveals 3 adenocarcinoma and 2 squamous cell carcinoma proteotypes that are associated with different patient outcomes, protein-phosphotyrosine profiles, signatures of activated pathways and candidate targets, and in adenocarcinoma, stromal immune features. These findings portend proteome-based NSCLC classification and treatment and support the PDX resource as a viable model for the development of new targeted therapies. With non-small cell lung cancer (NSCLC) being the leading cause of cancer deaths worldwide, the development of targeted therapies remains crucial. Here, the generation and multi-omics characterization of 137 NSCLC patient-derived xenografts provides a resource for potential classifications and targets.

Abstract
BACKGROUND Management of noncompressible truncal hemorrhage using resuscitative endovascular balloon occlusion of the aorta (REBOA) requires arterial pressure monitoring that can be logistically challenging in austere or emergency settings. Novel pressure transducer devices such as the Centurion Compass device (CD) (Medline, Northfield, IL) offer an alternative to traditional monitoring systems. We sought to assess the feasibility of maintaining permissive hypotension during intermittent REBOA in a porcine model guided by CD monitoring. METHODS Eight Yorkshire swine underwent 20% hemorrhage with an uncontrolled iliofemoral vascular injury. Time-based intermittent zone 1 REBOA was performed with volume-based resuscitation to maintain permissive hypotension. Proximal mean arterial pressures (MAPs) from a carotid arterial line (AL) were obtained and compared with CD readings from the proximal REBOA port. The operator was blinded to AL MAP, and the REBOA was managed with exclusively the CD. RESULTS Mean survival time was 100 minutes (range, 41-120 minutes) from injury. Arterial line and CD measurements were closely correlated (r = 0.94, p < 0.001). Bland-Altman analysis for comparison of clinical measurements demonstrated a mean difference of 6 mm Hg (95% confidence interval, -22 to 34 mm Hg) for all MAPs, with a mean difference of 3 mm Hg (95% confidence interval, -6 to 12 mm Hg) in a clinically relevant MAP of <65 mm Hg subset. CONCLUSION The CD represents a miniaturized and portable arterial pressure monitor that provides an accurate alternative to logistically burdensome AL monitoring to guide REBOA use. The device is highly accurate even at hypotensive pressures and can be used to guide intermittent REBOA strategies.

Abstract
Abstract
Background
Brain metastasis quantity may be a negative prognostic factor for patients requiring resection of at least one lesion.
Methods
We retrospectively reviewed patients who underwent surgical resection of brain metastases from July 2018 to June 2019 at our institution, and examined outcomes including overall survival (OS), progression free survival (PFS) and rates of local failure (LF). Patients were grouped according to the number of metastases at the time of surgery (single vs multiple).
Results
We identified 130 patients who underwent surgical resection as the initial treatment modality. At the time of surgery, 87 patients had only one lesion (control) and 43 had multiple (>1). Two-year OS for the entire cohort was 46%, with equal rates in both the multiple metastases group and the control group (p=0.335). 2-year PFS was 27%; 21% in the multiple metastases group and 31% in the control group (p=0.766). The rate of LF at 2-years was 32%, with equal rates in both the multiple lesion group and control group (p=0.889). On univariate analysis, multiplicity was not significantly correlated to OS (HR=0.80, 95% CI: 0.51-1.26, p=0.336), PFS (HR=1.06, 95% CI: 0.71-1.59, p=0.766) or LF (HR=1.06, 95% CI: 0.57-1.97, p=0.840). Multivariate analysis revealed preoperative tumor volume of the resected lesion to be the single correlate for OS (p=0.0032) and PFS (p=0.0081).
Conclusions
Having more than one metastasis does not negatively impact outcomes in patients treated with surgery. In carefully selected patients, especially those with large tumors, surgery should be considered regardless of the total number of lesions.

Abstract
BACKGROUND Social determinants of health (SDH) greatly influence outcomes during the first year of treatment in rheumatoid arthritis, a disease similar to polyarticular juvenile idiopathic arthritis (pJIA). We investigated the correlation of community poverty level and other SDH with the persistence of moderate to severe disease activity and functional disability over the first year of treatment in pJIA patients enrolled in the Childhood Arthritis and Rheumatology Research Alliance Registry. METHODS In this cohort study, unadjusted and adjusted generalized linear mixed effects models analyzed the effect of community poverty and other SDH on disease activity, using the clinical Juvenile Arthritis Disease Activity Score-10, and disability, using the Child Health Assessment Questionnaire, measured at baseline, 6, and 12 months. RESULTS One thousand six hundred eighty-four patients were identified. High community poverty (≥20% living below the federal poverty level) was associated with increased odds of functional disability (OR 1.82, 95% CI 1.28-2.60) but was not statistically significant after adjustment (aOR 1.23, 95% CI 0.81-1.86) and was not associated with increased disease activity. Non-white race/ethnicity was associated with higher disease activity (aOR 2.48, 95% CI: 1.41-4.36). Lower self-reported household income was associated with higher disease activity and persistent functional disability. Public insurance (aOR 1.56, 95% CI 1.06-2.29) and low family education (aOR 1.89, 95% CI 1.14-3.12) was associated with persistent functional disability. CONCLUSION High community poverty level was associated with persistent functional disability in unadjusted analysis but not with persistent moderate to high disease activity. Race/ethnicity and other SDH were associated with persistent disease activity and functional disability.

Abstract
Objective In patients with systemic lupus erythematosus (SLE) complement C1q is frequently targeted by autoantibodies (anti-C1q), that correlate best with active renal disease. Anti-C1q bind to largely unknown epitopes on the collagen-like region (CLR) of this highly functional molecule. Here we aimed at exploring the role of epitope-specific anti-C1q in SLE patients. Methods First, 22 sera of SLE patients, healthy controls and anti-C1q positive patients without SLE were screened for anti-C1q epitopes by a PEPperMAP® microarray, expressing CLR of C1q derived peptides with one amino acid (AA) shift in different lengths and conformations. Afterwards, samples of 378 SLE patients and 100 healthy blood donors were analyzed for antibodies against the identified epitopes by peptide-based ELISA. Relationships between peptide-specific autoantibodies and SLE disease manifestations were explored by logistic regression models. Results The epitope mapping showed increased IgG binding to three peptides of the C1q A- and three of the C1q B-chain. In subsequent peptide-based ELISAs, SLE sera showed significantly higher binding to two N-terminally located C1q A-chain peptides than controls (p < 0.0001), but not to the other peptides. While anti-C1q were associated with a broad spectrum of disease manifestations, some of the peptide-antibodies were associated with selected disease manifestations, and antibodies against the N-terminal C1q A-chain showed a stronger discrimination between SLE and controls than conventional anti-C1q. Conclusion In this large explorative study anti-C1q correlate with SLE overall disease activity. In contrast, peptide-antibodies are associated with specific aspects of the disease suggesting epitope-specific effects of anti-C1q in patients with SLE.

Abstract
BACKGROUND Radiotherapy (RT) and surgery (Sx) are effective in treating brain metastases. However, immune checkpoint inhibitors (ICI) have shown activity against asymptomatic melanoma brain metastases (MBM). BRAF/MEK inhibitors can be used to treat BRAF V600 mutation positive (BRAF+) MBM. METHOD We conducted an international survey among experts from medical oncology (MO), clinical oncology (CO), radiation oncology (RO), and neurosurgery (NS) about treatment recommendations for patients with asymptomatic BRAF+ or BRAF mutation negative (BRAF-) MBM. Eighteen specific clinical scenarios were presented and a total of 267 responses were collected. Answers were grouped and compared using Fisher's exact test. RESULTS In most MBM scenarios, survey respondents, regardless of specialty, favored RT in addition to systemic therapy. However, for patients with BRAF+ MBM, MO and CO were significantly more likely than RO and NS to recommend BRAF/MEK inhibitors alone, without the addition of RT, including the majority of MO (51%) for patients with 1-3 MBM, all <2cm. Likewise, for BRAF- MBM, MO and CO more commonly recommended single or dual agent ICI only and dual agent ICI therapy alone was the most common recommendation from MO or CO for MBM <2cm. When at least 1 of 3 MBM (BRAF+ or BRAF-) was >2cm, upfront Sx was recommended by all groups with the exception that MO and RO recommended RT for BRAF- MBM. CONCLUSIONS In most clinical settings involving asymptomatic MBM, experts recommended RT in addition to systemic therapy. However, recommendations varied significantly according to specialty, with MO and CO more commonly recommending dual systemic therapy alone for up to 9 BRAF- MBM <2cm.

Abstract
Purpose Intestinal stem cell markers play a significant role in esophageal adenocarcinoma carcinogenesis via Barrett’s esophagus; however, its utility as a prognostic biomarker has not been established. Methods We analyzed the immunohistochemical expression of intestinal stem cell markers, ASCL2 and LGR5, using whole slides (35 cases) and tissue microarray (TMA; 64 cases). On TMA slides, adjacent normal squamous epithelium, metaplastic glandular epithelium (Barrett's esophagus), and dysplastic glandular epithelium were inserted when applicable. Two pathologists semi-quantitatively scored stained slides independently, and the results were correlated with clinicopathologic factors and outcomes. Results In whole slides, 51% and 57% expressed high ASCL2 and high LGR5; in TMA, 69% and 88% expressed high ASCL2 and high LGR5, respectively. In TMA, high ASCL2 and low LGR5 expression significantly correlated to a higher number of involved lymph nodes (p=0.027 and p=0.0039), and LGR5 expression significantly correlated to the pathological stage (p=0.0032). Kaplan-Meier analysis showed a negative impact of high ASCL2 expression on overall survival (OS; WS p=0.0168, TMA p=0.0276) as well as progression-free survival (PFS; WS p=0.000638, TMA p=0.0466) but not LGR5. Multivariate Cox regression analysis revealed that ASCL2 expression is an independent prognostic factor for esophageal adenocarcinoma (OS; WS p=0.25, TMA p=0.011. PFS; WS p=0.012, TMA p=0.038). Analysis of the TCGA dataset showed that ASCL2 mRNA levels were correlated to nodal status but not overall survival. Conclusion High expression of the intestinal stem cell marker ASCL2 may predict unfavorable outcomes in surgically resected esophageal adenocarcinoma.
