Abstract
PURPOSE To examine whether overall survival (OS) differs for male and female patients with advanced soft-tissue sarcoma (STS). EXPERIMENTAL DESIGN The study included patients from Kaiser Permanente Northern California and Stanford Cancer Center with grade 2 and 3 locally advanced or metastatic STS whose tumor underwent next-generation sequencing. We used Cox regression modeling to examine association of sex and OS adjusting for other important factors. RESULTS Among 388 eligible patients, 174 had leiomyosarcoma (LMS), 136 had undifferentiated pleomorphic sarcoma (UPS), and 78 had liposarcoma. OS for male versus female patients appeared to be slightly better among the full cohort [HR = 0.89; 95% confidence interval (CI), 0.66-1.20]; this association appeared to be stronger among the subsets of patients with LMS (HR = 0.76; 95% CI, 0.39-1.49) or liposarcoma (HR = 0.74; 95% CI, 0.32-1.70). Better OS for male versus female patients was also observed among all molecular subgroups except mutRB1 and mutATRX, especially among patients whose tumor retained wtTP53 (HR = 0.73; 95% CI, 0.44-1.18), wtCDKN2A (HR = 0.85; 95% CI, 0.59-1.23), wtRB1 (HR = 0.73; 95% CI, 0.51-1.04), and among patients whose tumor had mutPTEN (HR = 0.37; 95% CI, 0.09-1.62). OS also appeared to be better for males in the MSK-IMPACT and TCGA datasets. CONCLUSIONS A fairly consistent pattern of apparent better OS for males across histologic and molecular subgroups of STS was observed. If confirmed, our results could have implications for clinical practice for prognostic stratification and possibly treatment tailoring as well as for future clinical trials design.

Abstract
Surgical resection remains the prefer option for bladder cancer treatment. However, the effectiveness of surgery is usually limited for the high recurrence rate and poor prognosis. Consequently, intravesical chemotherapy synergize with immunotherapy in situ is an attractive way to improve therapeutic effect. Herein, a combined strategy based on thermo-sensitive PLEL hydrogel drug delivery system was developed. GEM loaded PLEL hydrogel was intravesical instilled to kill tumor cells directly, then PLEL hydrogel incorporated with CpG was injected into both groins subcutaneously to promote immune responses synergize with GEM. The results demonstrated that drug loaded PLEL hydrogel had a sol-gel phase transition behavior in response to physiological temperature and presented sustained drug release, and the PLEL-assisted combination therapy could have better tumor suppression effect and stronger immunostimulating effect in vivo. Hence, this combined treatment with PLEL hydrogel system has great potential and suggests a clinically-relevant and valuable option for bladder cancer.

Abstract
INTRODUCTION The purpose of this study is to analyze the impact of a virtual multidisciplinary sarcoma case conference (VMSCC) on the outcomes of dermatofibrosarcoma protuberans (DFSP). METHODS We compared margin status after surgery and disease-free survival (DFS) on two cohorts of patients with DFSP, one diagnosed from 2010 to 2015 and one from 2016 to 2020 (before and after virtual multidisciplinary sarcoma case conference (VMSCC) within Kaiser Permanente Northern California (KPNC), using Kaplan-Meier curves and Cox proportional hazard regression models. RESULTS There was no significant difference between the two cohorts on demographics, tumor location, type of surgery, receipt of radiation, receipt of imatinib, or size of tumor. However, the percent of patients with positive margin after final surgery and the percent of local recurrence were significantly different: 6.5% and 6.3% for the 2010-2015 cohort, and .8% and 0% for the 2016-2020 cohort, respectively. CONCLUSION Our data suggest that the outcomes of DFSP improved significantly after the implementation of VMSCC.

Abstract
Introduction Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal malignancies with poor response to immune checkpoint inhibitors. The mechanism of such poor response is not completely understood. Methods We assessed T-cell receptor (TCR) repertoire and RNA expression at the single-cell level using high-dimensional sequencing of peripheral blood immune cells isolated from PDAC patients and from healthy human controls. We validated RNA-sequencing data by performing mass cytometry (CyTOF) and by measuring serum levels of multiple immune checkpoint proteins. Results We found that proportions of T cells (CD45+CD3+) were decreased in PDAC patients compared to healthy controls, while proportion of myeloid cells was increased. The proportion of cytotoxic CD8+ T cells and the level of cytotoxicity per cell were increased in PDAC patients, with reduced TCR clonal diversity. We also found a significantly enriched S100A9+ monocyte population and an increased level of TIM-3 expression in immune cells of peripheral blood in PDAC patients. In addition, the serum level of soluble TIM-3 (sTIM-3) was significantly higher in PDAC patients compared to the non-PDAC participants and correlated with worse survival in two independent PDAC cohorts. Moreover, sTIM-3 exhibited a valuable role in diagnosis of PDAC, with sensitivity and specificity of about 80% in the training and validation groups, respectively. We further established an integrated model by combining sTIM-3 and carbohydrate antigen 19- 9 (CA19-9), which had an area under the curve of 0.974 and 0.992 in training and validation cohorts, respectively. Conclusion Our RNA-seq and proteomic results provide valuable insight for understanding the immune cell composition of peripheral blood of patients with PDAC.

Abstract
Well-differentiated/de-differentiated liposarcoma (WDLPS/DDLPS) is one of the most common histologic subtypes of soft tissue sarcoma (STS); however, treatment options remain limited. WDLPS and DDLPS both exhibit the characteristic amplification of chromosome region 12q13-15, which contains the genes CDK4 and MDM2. DDLPS exhibits higher amplification ratios of these two and carries additional genomic lesions, including the amplification of chromosome region 1p32 and chromosome region 6q23, which may explain the more aggressive biology of DDLPS. WDLPS does not respond to systemic chemotherapy and is primarily managed with local therapy, including multiple resections and debulking procedures whenever clinically feasible. In contrast, DDLPS can respond to chemotherapy drugs and drug combinations, including doxorubicin (or doxorubicin in combination with ifosfamide), gemcitabine (or gemcitabine in combination with docetaxel), trabectedin, eribulin, and pazopanib. However, the response rate is generally low, and the response duration is usually short. This review highlights the clinical trials with developmental therapeutics that have been completed or are ongoing, including CDK4/6 inhibitors, MDM2 inhibitors, and immune checkpoint inhibitors. This review will also discuss the current landscape in assessing biomarkers for identifying tumors sensitive to immune checkpoint inhibitors.

Abstract
BACKGROUND Whether sex and co-mutations impact prognosis of patients with SMARCA4-mutated (mutSMARCA4) malignancies is not clear. METHODS This cohort included patients from Northern California Kaiser Permanente with next-generation sequencing (NGS) performed from August 2020 to October 2022. We used Cox regression modeling to examine the association between sex and overall survival (OS), adjusting for demographics, performance status, Charlson comorbidity index, receipt of treatment, tumor mutation burden (TMB), and TP53, KRAS, CDKN2A, STK11, and Keap1 co-mutations. RESULTS Out of 9221 cases with NGS performed, 125 cases (1.4%) had a mutSMARCA4. The most common malignancies with a mutSMARCA4 were non-small cell lung cancer (NSCLC, 35.2%), esophageal and stomach adenocarcinoma (12.8%), and cancer of unknown primary (11.2%). The most common co-mutations were p53 (mutp53, 59.2%), KRAS (mutKRAS, 28.8%), CDKN2A (mutCDKN2A, 31.2%), STK11 (mutSTK11, 12.8%), and Keap1 (mutKeap1, 8.8%) mutations. Male patients had substantially worse OS than female patients both among the entire mutSMARCA4 cohort (HR = 1.71, [95% CI 0.92-3.18]) with a median OS of 3.0 versus 43.3 months (p < 0.001), and among the NSCLC subgroup (HR = 14.2, [95% CI 2.76-73.4]) with a median OS of 2.75 months versus un-estimable (p = 0.02). Among all patients with mutSMARCA4, mutp53 versus wtp53 (HR = 2.12, [95% CI 1.04-4.29]) and mutSTK11 versus wtSTK11 (HR = 2.59, [95% CI 0.87-7.73]) were associated with worse OS. Among the NSCLC subgroup, mutp53 versus wtp53 (HR = 0.35, [0.06-1.97]) and mutKRAS versus wtKRAS (HR = 0.04, [0.003-.45]) were associated with better OS, while mutCDKN2A versus wtCDKN2A (HR = 5.04, [1.12-22.32]), mutSTK11 versus wtSTK11 (HR = 13.10, [95% CI 1.16-148.26]), and mutKeap1 versus wtKeap1 (HR = 5.06, [95% CI 0.89-26.61}) were associated with worse OS. CONCLUSION In our cohort of patients with mutSMARCA4, males had substantially worse prognosis than females, while mutTP53, mutKRAS, mutCDKN2A, mutSTK11 and mutKeap1were differentially associated with prognosis among all patients and among the NSCLC subgroup. Our results, if confirmed, could suggest potentially unidentified mechanisms that underly this sex and co-mutation-dependent prognostic disparity among patients whose tumor bears a mutSMARCA4.

Abstract
PURPOSE To examine the impact of TP53 gain-of-function (GOF) and non-GOF mutations on prognosis of advanced pancreatic ductal adenocarcinoma (PDAC) among patients with KRAS, CDKN2A, and SMAD4 comutations. METHODS This cohort included patients with locally advanced, recurrent, and de novo metastatic PDAC with next-generation sequencing performed from November 2017 to May 2022. We defined R175H, R248W, R248Q, R249S, R273H, R273L, and R282W as GOF and all other p53 mutations (mutp53) as non-GOF. We used Cox regression modeling to examine the association between GOF and non-GOF mutp53 and overall survival (OS), adjusting for demographics, performance status, Charlson comorbidity index, receipt of chemotherapy, and KRAS, CDKN2A, and SMAD4 comutations. RESULTS Of 893 total eligible patients, 68.5% had tumors with mutp53, 90.1% had KRAS mutations (mutKRAS), 44.7% had CDKN2A mutations (mutCDKN2A), and 17.0% had SMAD4 mutations. Among patients with mutp53, 121 had GOF and 491 had non-GOF. GOF mutp53 was associated with worse OS than non-GOF mutp53 (hazard ratio [HR], 1.27; 95% CI, 1.02 to 1.59) and wild-type p53 (wtp53; HR, 1.24; 95% CI, 0.98 to 1.57), whereas non-GOF was not associated with worse OS than wtp53 (HR, 0.95; 95% CI, 0.80 to 1.13). In addition, mutKRAS was associated with worse OS than wild-type KRAS in patients with mutCDKN2A (HR, 1.57; 95% CI, 0.88 to 2.80) but not in patients with wild-type CDKN2A (HR, 1.03; 95% CI, 0.76 to 1.39). CONCLUSION GOF and non-GOF mutp53 were associated with differential prognosis in advanced PDAC. The adverse effect of mutKRAS on OS appeared to be primarily driven by patients with mutCDKN2A. Our results provide new insight that could be helpful for prognostic stratification in clinical practice and for aiding future clinical trial designs.

Abstract
Water residue and replacement difficulty cause insufficient adhesive infiltration in demineralized dentin matrix (DDM), which produces a defective hybrid layer and thus a bonding durability problem, severely plaguing adhesive dentistry for decades. In this study, we propose that the unique properties of a highly hydrated interface of the porous DDM can give rise to 1 new type of interface, confined liquid water, which accounts for most of the residue water and may be the main cause of insufficient infiltration. To prove our hypothesis, 3 metal ions with increasing binding affinity and complex stability (Na+, Ca2+, and Cu2+) were introduced respectively to coordinate negatively charged groups such as -PO43-, -COO- abundant in the DDM interface. Strong chelation of Ca2+ and Cu2+ rapidly released the confined water, significantly improving penetration of hydrophobic adhesive monomers, while Na+ had little effect. A significant decrease of defects in the hybrid layer and a much decreased modulus gap between the hybrid layer and the adhesive layer greatly optimized the microstructure and micromechanical properties of the tooth-resin bonding interface, thus improving the effectiveness and durability of dentin bonding substantially. This study paves the way for a solution to the core scientific issue of contemporary adhesive dentistry: water residue and replacement in dentin bonding, both theoretically and practically.

Abstract
261 Background: Androgen deprivation therapy (ADT) plus either Abiraterone, Docetaxel or Enzalutamide (ADE) improves overall survival (OS) of men with metastatic M1 castrate-sensitive prostate cancer (mCSPC), compared to ADT alone and is currently standard of care. Men with mCSPC with a point mutation of the speckle-type pox virus and zinc finger mutation (mutSPOP) derive superior response to ADT compared to wild type SPOP. The additive benefit of ADE to ADT in this subclass of CSPC is unclear. We sought to evaluate the benefit of therapy in patients with mutSPOP in a real-world setting. Methods: Between November 2017 and July 2022, 1002, patients in the Kaiser Permanente Northern California (KPNC) health system with advanced prostate cancer had tumor specimens examined by next generation sequencing (NGS). Of these patients, we retrospectively identified 70 mCSPC patients with mutSPOP. Patient records were reviewed to determine baseline characteristics, therapy for CSPC, subsequent therapy for Castrate Resistant Prostate Cancer (CRPC), and clinical outcome. The primary outcome was progression-free survival (PFS) for patients who received ADT alone or ADT plus ADE. PFS was defined as time to either PSA progression by PCWG2 criteria, clinical progression, or time to next line of therapy. Results: Median age for the 70 patients with mutSPOP was 75 years (range 50-91). Thirty-six (51%) were non-Hispanic white; 11 (16%) were African American; and 13 (19%) were Asian. F133 was the most frequently mutated allele (64%), TP53 was the most common co-mutated gene (27%), and mutations in MSH2, MSH6 and BRCA1 were identified in one patient each. Two patients had concurrent ERG fusion. Thirty-six patients (51%) had a Gleason score 8-10 and 48 (69%) were diagnosed with de-novo metastatic disease. Twenty-seven patients (39%) received ADT alone, 41 (59%) received ADT + ADE, 2 patients elected observation only. PFS was 28.1 months (mos) for ADT alone vs 35 for ADT+ADE (p=0.08). Twenty-nine patients (41%) received 2nd line therapy at CRPC; among them 24 received ADT plus Abiraterone or Enzalutamide. Median PFS for all the CRPC patients who received 2nd line treatment was 15mos. Median PFS for CRPC patients who received 2nd line treatment with Abiraterone, or Enzalutamide was 15.3 mos. Median overall survival for the entire group was 173 mos (95% CI 135-NR). Conclusions: In this real-world study within KPNC, we confirmed the durable benefit of ADT based therapy in patients with mutSPOP. Patients with mutSPOP derived similar benefit regardless of 1st line therapy (ADT vs ADT + ADE). We also noted durable responses to abiraterone or enzalutamide for CRPC after initial treatment with ADE for CSPC. Confirmation of these findings from an another large NGS database is ongoing and will be reported later.

Abstract
β decay of proton-rich nuclei plays an important role in exploring isospin mixing. The β decay of ^{26}P at the proton drip line is studied using double-sided silicon strip detectors operating in conjunction with high-purity germanium detectors. The T=2 isobaric analog state (IAS) at 13 055 keV and two new high-lying states at 13 380 and 11 912 keV in ^{26}Si are unambiguously identified through β-delayed two-proton emission (β2p). Angular correlations of two protons emitted from ^{26}Si excited states populated by ^{26}P β decay are measured, which suggests that the two protons are emitted mainly sequentially. We report the first observation of a strongly isospin-mixed doublet that deexcites mainly via two-proton decay. The isospin mixing matrix element between the ^{26}Si IAS and the nearby 13 380-keV state is determined to be 130(21) keV, and this result represents the strongest mixing, highest excitation energy, and largest level spacing of a doublet ever observed in β-decay experiments.

Abstract
Abstract
Objectives
Mood disorders and strokes are often comorbid, and their health toll worldwide is huge. This study characterizes prognostic and etiological roles of mood disorders in stroke.
Methods
We tested if genetic susceptibilities for mood disorders could predict future strokes using the Malmö Diet and Cancer cohort (24 631 individuals). Additionally, Mendelian randomization was employed to further examine the causality using summary statistics from large genome wide association studies (mood disorders: up to 287,932 individuals; strokes: up to 446,696 individuals).
Results
Among 24,366 stroke-free participants at baseline, 2,632 individuals developed strokes, 2,172 of them ischemic, during a follow-up of up to 25 years. After all adjustments, participants in the highest quintile (5th quintile) of polygenic risk scores (PRS) for mood disorders had 1.46x (95% confidence interval (CI): 1.22–1.74) higher risk of strokes and 1.45x (95% CI: 1.19–1.77) higher risk of ischemic strokes compared to the lowest quintile (1st quintile) of PRS in women. Univariable and multivariable Mendelian randomization analyses showed that mood disorders had causal effect on smoking (odds ratio (OR) = 1.19, 95% CI: 1.07–1.31), type 2 diabetes mellitus (T2D, OR=1.22, 95% CI: 1.04–1.43) and women's body mass index (BMI, coefficient = 0.11, 95% CI: 0.01–0.21), whereas causal effects for smoking, T2D and BMI on stroke/ischemic stroke were consistently observed.
Conclusion
Our results suggest that mood disorders can cause stroke through smoking, T2D and BMI. Using PRS, women, who benefit from prevention and treatment of smoking, T2D and BMI, could possibly be early identified to prevent mood disorders and strokes.

Abstract
e16294 Background: Developmentally pancreas head derives from ventral bud while pancreas neck, body and tail derive from dorsal bud. Pancreatic ductal adenocarcinoma (PDAC) frequently harbors multiple mutations including KRAS, TP53, CDKN2A, and others. It is unknown how TP53 gain-of-function (GOF) and non-gain-of-function (non-GOF) mutations affect the prognosis. Methods: We retrospectively examined a cohort of 741 Kaiser Permanente (KP) patients with locally advanced/metastatic PDAC who had NGS performed to determine the association of KRAS (mutKRAS), TP53 (mutp53) and CDKN2A (mutCDKN2A) mutations (individually and in combination) with overall survival (OS). We used Cox modeling to estimate hazard ratios (HR) adjusted for age, sex, ethnicity, performance status, Charlston Comorbidity Index, chemotherapy received, anatomic location and co-mutations. We also analyzed the TCGA PDAC dataset to examine the association of OS with these same mutations. Results: In the KP cohort, patient ages ranged from 36 to 94 years and approximately 50% were female. In 384 patients PDAC was on the head, and 357 patients had PDAC on a non-head location (neck, body, and tail). Those with head PDAC had modestly better OS compared to non-head PDAC (HR = 0.87), and this appeared to be driven by the subsets of patients with wtp53 (HR = 0.68), with wtKRAS (HR = .74) and with wtCDKN2A (HR = .78). Approximately 67.5% of patients had mutp53, 89.2% had mutKRAS and 44.8% had mutCDKN2A. Among all KP patients, OS was similar for patients with mutp53 vs. wtp53 (HR = 1.05); worse for patients with mutKRAS vs. wtKRAS (HR = 1.26), and worse for patients with mutCDKN2 vs. wtCDKN2A (HR = 1.51). Interestingly, among patients with a GOF mutp53, those with mutCDKN2A had substantially worse OS vs patients with wtCDKN2A (HR = 2.56, 95% CI 1.46-4.50). In contrast, among patients with a non-GOF mutp53, patients with mutCDKN2A had only moderately worse OS compared to patients with wtCDKN2A (HR = 1.37, 95% CI 1.06-1.79). Analysis of the TCGA PDAC dataset showed that the number of mutations (0, 1, 2, or 3, of p53, KRAS and CDKN2A) was associated with incrementally worse OS ( p < .001). Conclusions: Better OS of head vs. non-head PDAC was primarily driven by patients with wtp53, wtKRAS, and wtCDKN2A. The adverse effect of mutCDKN2A on OS appears to be most pronounced in patients with GOF mutp53. Our TCGA analysis suggests interactions among TP53, KRAS and CDKN2A mutations in affecting PDAC survival.

Abstract
e23561 Background: TGCT/PVNS is an uncommon benign but locally aggressive tumor that affects joints and can lead to significant morbidity. It is characterized in most cases by a t(1;2) translocation that leads to overexpression of colony-stimulating factor 1 (CSF-1) and the accumulation of inflammatory cells that express CSF-1 receptor (CSF-1R) in the affected joints. Imatinib inhibits the tyrosine kinase activity of CSF-1R. Methods: We retrospectively reviewed patients with TGCT/PVNS who received treatment with imatinib within Kaiser Permanente Northern California. Results: Nine patients with relapsed TGCT/PVNS were treated with imatinib from 2019 to 2022. Median age was 43 years. 6 patients were female. The imatinib dose was 400 mg daily. All patients had been treated with surgery previously and relapsed, and further surgery was considered not to be beneficial. All patients presented with persistent joint pain that affected joint mobility and walking. After imatinib therapy was initiated, 7 patients (78%) reported significant improvement in their symptoms, while 2 patients (22%) reported no significant changes. Improvement in symptoms occurred soon after starting therapy, ranging from 3 days to 5 weeks. 8 patients (89%) had stable disease by RECIST criteria based on MRI, and 1 patient was not evaluable. 5 patients are still receiving imatinib currently. The longest treatment duration is 27 months. 4 patients required a dose reduction secondary to toxicity, and 3 patients discontinued therapy (2 patients with G3/4 hepatotoxicity and 1 patient self-discontinued treatment). 2 patients who discontinued imatinib continue to experience resolution of joint pain and other symptoms 10 and 24 months later respectively. Conclusions: Our study shows that treatment with imatinib can result in rapid and lasting symptomatic improvement in patients with relapsed TGCT/PVNS, even after treatment discontinuation. This suggests that imatinib can be an effective and safe treatment option for patients with relapsed TGCT/PVNS refractory or not amenable to further surgery.

Abstract
e23563 Background: Pazopanib is approved for second or later line therapy for advanced soft tissue sarcoma (STS). Whether or not Pazopanib and radiation have cooperative effect remains unclear. Methods: We retrospectively reviewed 10 patients with locally advanced or metastatic soft tissue sarcoma treated with pazopanib either at the start of radiation or within 4 weeks after the start of radiation. Results: Seven patients were females and age ranged 39-80. Four patients had undifferentiated pleomorphic sarcoma (UPS), two leiomyosarcoma (LMS), two synovial sarcoma (SS), and two dedifferentiated liposarcoma (DDLS). All patients had a large primary tumor that was unresectable with or without distant metastasis. The disease burden with the distant metastasis was low for patients with metastatic disease. Radiation was delivered to the large primary tumor with dose ranging from 15 to 50 Gy (median dose 30 Gy). Pazopanib dose ranged from 400 to 800 mg (majority received 600-800 mg). Eight patients had received one to two lines of chemotherapy previously. Three patients whose pazopanib treatment is still ongoing with stable disease (SD) at 4 (UPS), 25 (LMS), and 26 (DDLS) months respectively. One patient (UPS) with SD discontinued Pazopanib after 3.5 months due to liver toxicities. One patient with SS obtained PR that lasted for 11 months and one patient with SS had SD for 12 months. One patient with relapsed abdominal DDLS obtained a PR followed by resection of residual tumor 8 months after the start of Pazopanib, however, disease relapsed again 3 months after the resection. Three other patients had SD for 8, 8 and 13 months respectively. Conclusions: Our results suggest that Pazopanib at the start or within 4 weeks of radiation in palliative dose can achieve prolonged disease control for patients with locally advanced or metastatic STS. This approach can be considered for selective STS patients with large primary tumor and low distant disease burden.

Abstract
Objective: To analyze the prenatal diagnosis results and pregnancy outcomes of conotruncal defects (CTD) fetuses, and to explore the correlation between the CTD and chromosome diseases. Methods: A total of 297 cases of invasive prenatal diagnosis and chromosome analysis were collected at the Prenatal Diagnosis Center of Guangzhou Women and Children's Medical Center due to CTD from January 1st, 2011 to December 31th, 2019. According to ultrasonic diagnosis, CTD fetuses were divided into 6 subtypes: tetralogy of Fallot (109 cases), pulmonary atresia (30 cases), transposition of the great arteries (77 cases), double outlet right ventricle (53 cases), truncus arteriosus (14 cases) and interrupted aortic arch (14 cases). According to whether they were combined with intracardiac or extracardiac abnormalities, they were divided into simple group (134 cases), combined with other intracardiac abnormalities group (86 cases), combined with extracardiac abnormalities group (20 cases), combined with intracardiac and extracardiac abnormalities group (37 cases) and only combined with ultrasound soft marker group (20 cases), the last 4 groups were referred as non-simple types. The chromosome test results and pregnancy outcomes of each type and group were analyzed retrospectively. Results: Among the 297 CTD fetuses, the chromosome abnormality rate was 17.5% (52/297). There were 21 cases of abnormal chromosome number, 28 cases of pathogenetic copy number variantions and 3 cases of mosaics. All the 19 cases of micropathogenic fragments smaller than 5 Mb were detected by chromosomal microarray analysis (CMA). Among all the subtypes of CTD, the chromosomal abnormality rate of truncus arteriosus was the highest, at 7/14; while the rate of transposition of the great arteries was the lowest, at 5.2% (4/77). There were significant differences in the rate of chromosomal abnormalities between simple and non-simple types [10.4% (14/134) vs 23.3% (38/163); χ²=8.428, P=0.004]. In each group, the chromosomal abnormality rate was the highest in the combined with intracardiac and extracardiac abnormalities group, at 37.8% (14/37), and the lowest in the simple group, at 10.4% (14/134). There was no significant difference in the rate of chromosomal abnormalities in all subtypes of simple group (all P>0.05). Among 112 cases of live birth, 1 case was 22q11.2 microdeletion syndrome, 5 cases of postnatal clinical diagnosis and prenatal ultrasound diagnosis were not completely consistent, 5 cases died after birth. Conclusions: The incidence of chromosomal abnormalities is high in fetuses with CTD. CTD fetuses with concurrent extrapardiac malformations are more likely to incorporate chromosomal abnormalities. CMA technology could be used as a first-line genetic detection method for CTD. After excluding chromosomal abnormalities, most of the children with CTD have good prognosis.

Abstract
PURPOSE To examine the association of gain-of-function (GOF) and non-gain-of-function (non-GOF) TP53 mutations with prognosis of metastatic right-sided (RCC) versus left-sided colorectal cancer (LCC). METHODS This cohort study included patients with metastatic colorectal cancer (CRC) who had next-generation sequencing performed from November 2017 to January 2021. We defined R175H, R248W, R248Q, R249S, R273H, R273L, and R282W as GOF and all other mutp53 as non-GOF. We used Cox regression modeling to examine the association between GOF and non-GOF mutp53 and overall survival (OS), adjusting for age, sex, ethnicity, performance status, Charlson comorbidity index and receipt of chemotherapy. RESULTS Of total 1,043 patients, 735 had tumors with mutp53 and 308 had wild-type p53 (wtp53). GOF was associated with worse OS than non-GOF mutp53 only in LCC (hazard ratio [HR] = 1.66 [95% CI, 1.20 to 2.29]), but not in RCC (HR = 0.79 [95% CI, 0.49 to 1.26]). Importantly, RCC was associated with worse OS than LCC only in the subset of patients whose CRC carried non-GOF (HR = 1.76 [95% CI, 1.30 to 2.39]), but not GOF mutp53 (HR = 0.92 [95% CI, 0.55 to 1.53]) or wtp53 (HR = 0.88 [95% CI, 0.60 to 1.28]). These associations were largely unchanged after also adjusting for RAS, BRAF, and PIK3CA mutations, and microsatellite instability-high. CONCLUSION Poorer survival of patients with metastatic RCC versus LCC appeared to be restricted to the subset with non-GOF mutp53, whereas GOF versus non-GOF mutp53 was associated with poorer survival only among patients with LCC. This approach of collectively classifying mutp53 into GOF and non-GOF provides new insight for prognostic stratification and for understanding the mechanism of sidedness-dependent prognosis. If confirmed, future CRC clinical trials may benefit from incorporating this approach.

Abstract
Objective: To investigate the effect of anti-vascular endothelial growth factor (VEGF) therapy on the expression levels of transforming growth factor-beta (TGF-β) and its related microRNAs in the vitreous of patients with proliferative diabetic retinopathy (PDR). Methods: This cross-sectional study included 67 patients (67 eyes), 38 males and 29 females, aged (54.37±11.70) years, who underwent vitrectomy from June 2020 to February 2021. There were 45 PDR patients (45 eyes), including 29 patients (29 eyes) without anti-VEGF therapy in the disease group and 16 patients (16 eyes) who were admitted at 7 days after anti-VEGF therapy in the treatment group. The other 22 idiopathic macular hole patients (22 eyes) were in the negative control group. The microRNA (hsa-miR-24-3p and hsa-miR-197-3p) levels in the vitreous of 36 patients (12 cases randomly chosen from each group) were detected by quantitative reverse transcription polymerase chain reaction. The levels of TGF-β and VEGF-A in the vitreous of 67 patients were detected by enzyme-linked immunosorbent assay. Target gene prediction of hsa-miR-24-3p and hsa-miR-197-3p was performed on RNAhybrid, miRanda and TargetScan7.2 databases, and pathway enrichment analyses were conducted for all target mRNAs. One-way ANOVA was used to compare the levels of growth factors and microRNAs among the three groups, and the least significant difference method was used for multiple comparisons between groups. Pearson correlation test was used to analyze the correlation between growth factors and microRNAs. Results: The expression levels of VEGF-A, TGF-β, hsa-miR-24-3p and hsa-miR-197-3p were (158.15±17.72) pg/ml, (640.47±24.80) pg/ml, 0.81±0.11 and 1.07±0.15 in the control group, (1 047.54±26.61) pg/ml, (3 553.17±92.61) pg/ml, 8.50±2.33 and 12.23±3.38 in the disease group, and (778.10±27.73) pg/ml, (3 376.02±78.83) pg/ml, 4.54±0.67 and 3.90±0.65 in the treatment group, respectively. All indicators were significantly higher in the disease group than those in the control group (F=355.581, 440.538, 7.546 and 7.546; all P<0.05). The expression levels of VEGF-A, hsa-miR-24-3p and hsa-miR-197-3p in the treatment group were significantly lower than those in the disease group (all P<0.05). The concentration of TGF-β was not statistically significantly lower in the treatment group compared to the disease group. The concentrations of VEGF-A and TGF-β were significantly positively correlated with the expression levels of hsa-miR-24-3p and hsa-miR-197-3p in the vitreous of randomly chosen 36 patients (r=0.48, 0.51, 0.40 and 0.42; all P<0.05). Pathway enrichment analysis showed that some target mRNAs of hsa-miR-24-3p and hsa-miR-197-3p were involved in VEGF and TGF-β signal pathways. Conclusions: In the vitreous of patients with PDR, hsa-miR-24-3p and hsa-miR-197-3p were positively related to VEGF-A and TGF-β, and may be potential risk factors. Anti-VEGF treatment can significantly reduce the expression level of TGF-β-related microRNAs, namely hsa-miR-24-3p and hsa-miR-197-3p, but cannot effectively reduce the concentration of TGF-β, suggesting that combined anti-TGF treatment may be beneficial for delaying the progression of PDR. Furthermore, it may be a new research direction of PDR to validate the target mRNAs of hsa-miR-24-3p and hsa-miR-197-3p involved in VEGF and TGF-β signal pathways.

Abstract
Abstract
Background
The impact of distance from residence to Tertiary Referral Hospital and cardiovascular (CV) outcomes in patients with coronary artery disease (CAD) is unknow. Despite longer travel distances hinder access to healthcare and may worsen CV outcomes, we hypothesize that Mediterranean lifestyle and behaviors in distant rural areas may be associated with a reduced risk of CV death and events.
Purpose
To investigate the association between travel distance to Tertiary Hospital and mid-term cardiovascular outcomes in a population of CAD patients in Southern Spain.
Methods
Retrospective study including all patients discharged after percutaneous coronary intervention (PCI) at a high-volume center in Southern Spain during 2018. Those belonging to another healthcare area were excluded. One-way driving distances from residence to hospital were computed using Google Maps Distance Matrix API with R package “gmapsdistance”. Patients were stratified into tertiles according to travel distance (short, STD; intermediate, ITD; and long, LTD). Kaplan-Meier (KM) and Multivariable Cox regression (adjusted for age, sex, atrial fibrillation, cancer history, prior revascularization and clinical presentation) were used to assess the impact of travel distance on CV death and a composite outcome of MACE (Myocardial Infarction, unplanned PCI and CV death).
Results
Of 1005 patients discharged after PCI during the study period, 966 met the selection criteria. Flowchart and baseline characteristics by distance groups are presented in Figure 1. Median travel distance tertiles were 6.1 (STD), 41.7 (ITD) and 78.4 (LTD). During a median follow-up of 31 (IQR 28–35) months, 50 cardiovascular deaths [STD 27 (8.4%), ITD 13 (4%), LTD 10 (3.1%), p=0.006)] and 63 MACE occurred [STD 45 (13.9%), ITD 37 (11.5%), LTD 26 (8.1%), p=0.060)]. KM curves for the three distance groups are shown in Figure 2. In univariable and multivariable Cox models, longer travel distances were associated with better outcomes, as for every 10 Km increase, there was a 11% and 7% decrease in the hazards of CV death (HR adj: 0.89, CI 0.82–0.98, p=0.029) and of MACE (HR adj: 0.93, CI 0.87–0.99, p=0.025), respectively.
Conclusion
Travel distance was inversely associated with CV events in a population of CAD patients in Southern Spain. Patients in the first tertile of distance had a higher rate of CV death. Multicenter studies involving other Mediterranean regions are needed to confirm these findings and to look for explanations.

Abstract
Abstract
Background
A physiological assessment with the fractional flow reserve (FFR) or instantaneous wave-free ratio (iFR) is strongly recommended by the European Guidelines of Revascularization to guide percutaneous coronary intervention (PCI) decision making in intermediate coronary stenosis. However, data supporting its use in the pro-inflammatory setting of ACS is weak.
Purpose
To analyze the usefulness of a physiological coronary evaluation with iFR of nonculprit lesions in patients with ACS.
Methods
Retrospective multicenter study including patients with ACS and underwent successful revascularization of the culprit vessel and had other nonculpritlesions physiologically evaluated with the iFR between January 2017 and December 2019. The primary endpoint was a composite of cardiac death, nonfatal myocardial infarction, stent thrombosis and new revascularization (MACEs).
Results
A total of 356 patients with 472 nonculprit lesions were included. The mean age was 66±11 years. The clinical presentation was non-ST-segment elevation myocardial infarction (NSTEMI) in 235 patients and ST-segment elevation myocardial infarction (STEMI) in 121 patients. After a mean follow-up period of 22±10 months, the primary endpoint occurred in 32 patients (9%). There were no differences in outcomes regarding iFR induced treatment strategy (patients with all lesions revascularized vs. patients with at least one lesion deferred for revascularization, 10.5 vs 8.4%, p=0.476).
Conclusion
The use of the iFR to guide percutaneous coronary intervention decision making in nonculprit lesions seems to be safe, with an acceptable percentage of MACEs at the mid-term follow-up.

Abstract
Non-small cell lung cancer (NSCLC) is prevalent worldwide and has a high mortality rate. Even if mesenchymal stem cells (MSCs) are suggested as cancer treatment, the studies of their effects on NSCLC cells contradict each other, mainly due to utilization of two-dimensional (2D) culture system. Three-dimensional (3D) culture systems resemble tissue organization in vivo. Here we comprehensively explore the inhibitory effects of MSCs on NSCLC cells in a 3D culture system. We confirmed that the inhibitory effects of 3D-cultured MSCs (3D-MSCs) on the proliferation and migration of NSCLC cells are greater than that of the 2D-cultured MSCs. 3D-MSCs overexpress IL-24, which serve as the key factor enhancing antitumor effects of MSCs. In these cells, IL-24 affects p38 MAPK and CXCR4/AKT pathways. Overall, this study provides the support for use of MSCs in tumor.

Abstract
Objective: To evaluate the value of whole exome sequencing (WES) in prenatal clinical application. Methods: A total of 1 152 cases of congenital abnormal [including structural malformation, nuchal translucency (NT) thickening and intrauterine growth restriction] with traditional prenatal diagnosis [including G-band karyotype analysis and chromosome microarray analysis (CMA)] negative were analyzed. The congenital abnormal fetuses were divided into retrospective group and prospective group according to the time of WES detection, that is whether the pregnancy termination or not. According to the specific location of fetal malformation and their family history, the cohort was divided into subgroups. The clinical prognosis of all fetuses were followed up, and the effect of WES test results on pregnancy decision-making and clinical intervention were analyzed. According to the follow-up results, the data of fetuses with new phenotypes in the third trimester or after birth were re-analyzed. Results: Among 1 152 families who received WES, 5 families were excluded because of nonbiological parents. Among the remaining 1 147 families, 152 fetuses obtained positive diagnosis (13.3%,152/1 147), including 74 fetuses in the retrospective group (16.1%,74/460) and 78 fetuses in the prospective group (11.4%,78/687). In fetuses with negative CMA and G-band karyotype analysis results but new phenotypes in the third trimester or after birth, the positive rate by WES data re-analysis was 4.9% (8/163). A total of 34 (21.3%, 34/160) fetuses were directly affected by the corresponding positive molecular diagnosis. Among 68 cases of live births with diagnostic variation grade 4, 29 cases (42.7%, 29/68) received appropriate medical intervention through rapid review of WES results. Conclusions: WES could increase the detection rate of abnormal fetuses with negative G-banding karyotype analysis and CMA by 13.3%. Prenatal WES could guide pregnancy decision-making and early clinical intervention. It might be an effective strategy to pay attention to the special follow-up of the third trimester and postnatal fetus and to re-analyze the WES data.

Abstract
PURPOSE Management of soft tissue and bone sarcoma presents many challenges, both diagnostically and therapeutically, and requires multidisciplinary collaboration; however, such collaboration is often challenging to establish, especially in the community setting. We share our experiences of a virtual multidisciplinary sarcoma case conference (VMSCC). METHODS We conducted retrospective review of the VMSCC data-initially via Webex, now Microsoft Teams-and the surveys of referring physicians to understand the feasibility and value of the VMSCC. RESULTS The VMSCC was established in March 2013 in Kaiser Permanente Northern California with consistent participation of the Departments of Musculoskeletal Oncology (orthopedic oncology), Musculoskeletal Radiology, Pathology, Medical Oncology, Radiation Oncology, Nuclear Medicine, Surgical Oncology, and Genetics. Pediatric Oncology participated ad hoc when pediatric sarcoma cases were presented. Referrals were from multiple specialties and regions, including the Kaiser Permanente Mid-Atlantic and Hawaii regions. From March 2013 to December 2019, 1,585 cases were reviewed encompassing 36 histologic types. More than 300 cases were reviewed per year from 2017 to 2019. Survey results of referring physicians demonstrate that the VMSCC enhanced the confidence of treating physicians, and its recommendations frequently led to treatment changes. CONCLUSION Establishing a valuable community-based VMSCC is feasible. VMSCC recommendations frequently led to treatment changes and improved the confidence of treating physicians.

Abstract
OBJECTIVES Podocyte pyroptosis, characterized by inflammasome activation, plays an important role in inflammation-mediated diabetic nephropathy (DN). Our study aimed to investigate whether miR-21-5p in macrophage-derived extracellular vesicles (EVs) could affect podocyte injury in DN. METHODS EVs were extracted after the treatment of RAW 264.7 (mouse macrophage line) with high glucose (HG). The podocyte pyroptosis was determined using the flow cytometry and the western blot. After the knockdown of miR-21-5p in HG-induced RAW264.7 cells, we injected the extracted EVs into DN model mice. RESULTS The level of miR-21-5p was higher in HG-stimulated macrophage-derived EVs than in normal glucose-cultured macrophage-derived EVs. The co-culture of EVs and podocytes promoted reactive oxygen species (ROS) production and activation of inflammatory in MPC5 cells (mouse podocyte line). However, restraint of miR-21-5p in EVs reduced ROS production and inhibit inflammasome activation in MPC5 cells, thereby reducing podocytes injury. Meanwhile, we found that miR-21-5p inhibited the A20 expression through binding with its 3'-untranslated regions in MPC5 cells. Further studies showed that A20 was also involved in the regulation of miR-21-5p of RAW 264.7-derived EVs on MPC5 injury. At the same time, it was also proved in the DN model mice that miR-21-5p in macrophage-derived EVs could regulate podocyte injury. CONCLUSION MiR-21-5p in macrophage-derived EVs can regulate pyroptosis-mediated podocyte injury by A20 in DN.

Abstract
e15578 Background: TP53 tumor suppressor gene is mutated in approximately 50% of colorectal cancer (CRC). How TP53 mutations are associated with the prevalence of the other common genomic alterations such as RAS (KRAS/NRAS), BRAF, PI3KCA, as well as microsatellite stability (MSI) is not clear. Methods: We investigated the impact of TP53 mutations on other common genomic alterations and survival in patients with metastatic CRC using the NGS data within Kaiser Permanente Northern California (KPNC). Results: From November 2017 to January 2021, genomic profiling was performed on 1056 patients with metastatic CRC, of whom 740 patients harbored a TP53 mutation (TP53mut) and 316 patients had wild-type TP53 (TP53wt). We found that median overall survival (OS) was similar between the TP53wt and TP53mut patients (50.1 vs 47.5 months, p = 0.9), however, the percent with a Ras mutation was significantly higher in patients with TP53wt compared to TP53mut (63.2 vs 45.2%, p = 0.0001). Interestingly, the percent with MSI-high was also significantly higher in TP53wt than TP53mut patients (11.1 vs 1.4%, p = 0.0001), however, the response rate of the MSI-high patients to immune checkpoint inhibitor (ICI) was similar (40 vs 37.5%). In addition, a significantly higher percent of patients with TP53wt had PI3KCA mutations and a significantly lower percent had c-Myc amplifications compared to patients with TP53mut (PI3KCA, 32 vs 10.7%, p = 0.0001; c-Myc, 1.26 vs 4.6%, p = 0.008). There was no significant difference in the percent of BRAF mutations between the two patient populations (6.2 vs 9.8%). A significantly higher percent of patients with TP53wt and a PI3KCA mutation had a Ras mutation compared to patients with TP53mut and a PI3KCA mutation (81.2 vs 57%, p = 0.0004). However, TP53 mutation status was not significantly associated with the OS of patients with either a Ras, or BRAF, or PI3KCA mutation, or combination of Ras and PI3KCA mutations. Conclusions: TP53 mutation is associated with decreased prevalence of Ras, PI3KCA mutation and MSI-high in patients with metastatic CRC, however, without impacting the OS or response rate to ICI.

Abstract
3585 Background: TP53 mutation is present in approximately 50% of metastatic colorectal cancer (CRC). The spectrum of the TP53 mutations is extremely broad including approximately 80% missense mutations. Several missense mutations have been found to possess gain-of-function (GOF) properties in cell line and animal studies, however, confirmation of the concept of GOF in human malignancies is still lacking. Methods: We investigated the impact of TP53 GOF mutations in patients with metastatic CRC using the NGS data within Kaiser Permanente Northern California (KPNC), a large integrated healthcare system. Results: From November 2017 to January 2021, genomic profiling by StrataNGS was performed on 8658 patients, with 1056 patients being metastatic CRC, among whom 740 patients harbored a TP53 mutation (TP53mut) and 316 patients had wild-type TP53 (TP53wt). Ras (KRAS and NRAS) and BRAF mutation appropriately discriminated the overall survival (OS) of patient populations with either TP53wt or TP53mut, confirming the validity of our dataset. We identified seven GOF TP53 mutations (R175H, R248W, R248Q, R249S, R273H, R273L, R282W) in these CRC patients. We show that different GOF mutation differentially impacts the OS. Patients whose CRC harbored TP53mut R248W, R249S, and R282W (poor prognostic TP53mut, N = 47) had significantly worse OS versus patients whose CRC harbored TP53mut R248Q, R175H, R273H and R273L (N = 160, median OS 29.4 vs 44.2 months, HR 0.47, p = 0.007). The OS of the poor prognostic TP53mut patients was also significantly inferior compared to patients whose CRC harbored all other TP53 mutations (N = 1099, median OS 50.1 months, HR 0.55, p = 0.01) or TP53wt (N = 316, median OS 47,5 months, HR 0.54, p = 0.01). The demographics and the percent of Ras, BRAF, and PI3KCA mutations were similar except that the patients with the poor prognostic TP53mut had significantly higher percent of Ras mutation compared to the rest of the GOF TP53mut patients (p = 0.035). When compared to R248Q alone, R248W confers worse OS (median OS 36.3 vs 63.2 months, p = 0.05). Conclusions: Our data suggest that different TP53 GOF mutations are associated with very different clinical outcomes. Additional studies identifying specific TP53 GOF mutations that impact outcomes may provide further insight for drug development and clinical trial design.

Abstract
None Patients with metastatic uterine leiomyosarcoma (uLMS) have poor prognosis due to limited treatment options, especially when disease progresses on doxorubicin and gemcitabine-docetaxel regimens. Here we report a patient whose metastatic uLMS contains a BRCA2 deep deletion as well as TP53 and PTEN deep deletion. The patient responded rapidly to olaparib, a poly (ADP-ribose) polymerase inhibitor, after progressing on gemcitabine-docetaxel, doxorubicin, and temozolomide regimens. This case report shall be helpful to the treatment of other patients with metastatic uLMS that harbors a BRCA2 mutation or deletion.

Abstract
PURPOSE Quantifying the impact of a multidisciplinary cancer case conference on patient outcome and care quality remains challenging. PATIENTS AND METHODS We prospectively investigated the impact of our virtual multidisciplinary sarcoma case conference (VMSCC) on treatment plan in patients presented to the VMSCC from July to October 2020 (prospective cohort) and retrospectively in patients with metastatic or locally advanced high-grade soft-tissue sarcoma (STS) reviewed in the VMSCC in 2016 and 2017 (high-grade STS cohort). We also investigated the factors related to the nonadherence to the VMSCC-recommended plan in both cohorts. RESULTS In both cohorts, approximately 28% of the patients were referred to the VMSCC for review without a treatment plan. In significantly more cases, referring physicians outside of the sarcoma group did not have a plan formulated before the VMSCC review compared with the referring physicians within the sarcoma group. In 28.2% (prospective cohort) and 19.5% (high-grade STS cohort) of the patients, VMSCC recommended a different plan. The adherence to the VMSCC-recommended plan was 87.9% and 83.1%, respectively. The causes of the nonadherence were primarily due to disease progression or patient's decision against recommended therapy. The median overall survival for the high-grade STS cohort was 26 months. CONCLUSION VMSCC affected the treatment plan in approximately 50% of the patients in both cohorts. The median overall survival of the patients with high-grade STS reviewed by the VMSCC in our cohort is comparable with the literature.

Abstract
INTRODUCTION NUT carcinoma is an extremely rare disease and yet extremely aggressive with 2-year survival of only approximately 19% and median survival of 6 to 9 months. CASE PRESENTATION We report here 2 successfully treated patients with durable complete remission (CR) after concurrent chemotherapy and radiation using 2 completely different chemotherapy regimens. One patient had extremely high tumor burden and obtained CR with ifosfamide and etoposide concurrently with radiation. One patient with low tumor burden obtained CR with carboplatin and paclitaxel concurrently with radiation. Interestingly, both patients had high PD-L1 expression in the tumor that may be associated with the favorable outcome. CONCLUSION Our experiences with these 2 successfully treated patients offer insight for the management of NUT carcinoma.

Abstract
PURPOSE An in-depth understanding of the mechanism of thyroid cancer progression will help identify patients with thyroid cancer with a high risk of recurrence and metastasis. Although studies have pointed out that the senescence of thyroid tumor cells may stimulate TAMs and cause a series of changes. However, the role of TAMs in aging thyroid cancer cells is still unknown. The aim of this study was to investigate the function of TAMs in aging thyroid cancer cells. METHODS We conducted in vitro model studies based on the K1 cell line to induce tumor cell senescence and study its effect on the differentiation of macrophages, flow cytometry was used to confirm polarization of macrophages, transwell assay was used to confirm changes of invasion and migration of tumor cells. RESULT Our data indicate that aging thyroid tumor cell lines trigger the polarization of M2-like macrophages, accompanied by increased expression of CCL17, CCL18, IL-18, and TGFβ1. This event is caused by the activation of the NFκB pathway upregulation of CXCL2 and CXCL3 is related. Further studies have shown that differentiated M2-like macrophages promote tumor cell migration (but have no effect on cell proliferation). CONCLUSION Our study indicating that the interaction between tumor and TAMs also occurs in the advanced stages of thyroid tumors and will lead to faster tumors progress.

Abstract
Objective: To investigate the frequency and severity of systemic reactions (SRs) to standardized house dust mite subcutaneous immunotherapy (SCIT) in patients with perennial allergic rhinitis (AR), and to analyze the clinical risk factors. Methods: The clinical data of 362 patients including 209 males and 153 females, aged from 5 to 55 years old receiving SCIT at the Department of Otorhinolaryngology, the Third People's Hospital of Changzhou were collected from May 2014 to July 2017. The SRs were classified as early-onset and delayed-onset, and 4 grades (grade Ⅰ to Ⅳ) to assess severity. The records of SRs were retrospectively analyzed, including the numbers/frequencies, symptoms and signs, onset of reaction and treatment. And the relationships between SRs and patient's age, gender, allergen injection dose, accompanied allergic diseases were explored. All the statistical analyses were conducted using SPSS 19.0. Results: There were 57 cases (15.75%) of SRs in 362 patients. All the patients received a total of 12 308 injections and 111 SRs (0.90%) were observed. Among them, 31 (27.93%) were early-onset reactions and 80 (72.07%) were delayed-onset reactions; most of the SRs were grade Ⅰ reactions (n=83, 74.78%), followed by grade Ⅱ (n=25, 22.52%), grade Ⅲ (n=3, 2.70%), and no fatal reactions occurred. The incidence of SRs in patients>14 years old was higher than that in patients ≤14 years old according to the number of cases and injections (35.14% vs 13.54%, 2.34% vs 0.76%, χ(2) value was 11.679, 28.162, respectively, all P<0.05), but no significant differences of SRs were observed in gender (18.66% vs 11.76%, 5.98% vs 5.62%, χ(2) value was 3.166, 0.095, respectively, all P>0.05). Fifteen SRs (13.51%) occurred during the build-up phase and 96 (86.49%) during the maintenance phases. SRs could occur in lots of dose phases, and 95 (85.59%) were distributed at high concentrations more than 40 000 SQ-U. The incidence of SRs in patients with multiple allergic diseases was significantly higher than that in patients with AR alone, with asthma or atopic dermatitis (30.67% vs 11.85%, χ(2)=15.875, P<0.001). Meanwhile, the incidence of SRs in patients with pure AR was also significantly lower than that in patients with other allergic diseases (5.26% vs 20.56%, χ(2)=13.783, P<0.001). Conclusions: The incidence of SRs is less than 1% according to the injection times, the severity of SRs is mostly slight, and the safety and tolerance are good during standardized house dust mite SCIT in perennial AR patients. Delayed-onset SRs are more common. The incidence of SRs is significantly correlated with age, high dose of allergen vaccine injection, and concomitant other allergic diseases (asthma, atopic dermatitis, etc).

Abstract
β-delayed one-proton emissions of ^{22}Si, the lightest nucleus with an isospin projection T_{z}=-3, are studied with a silicon array surrounded by high-purity germanium detectors. Properties of β-decay branches and the reduced transition probabilities for the transitions to the low-lying states of ^{22}Al are determined. Compared to the mirror β decay of ^{22}O, the largest value of mirror asymmetry in low-lying states by far, with δ=209(96), is found in the transition to the first 1^{+} excited state. Shell-model calculation with isospin-nonconserving forces, including the T=1, J=2, 3 interaction related to the s_{1/2} orbit that introduces explicitly the isospin-symmetry breaking force and describes the loosely bound nature of the wave functions of the s_{1/2} orbit, can reproduce the observed data well and consistently explain the observation that a large δ value occurs for the first but not for the second 1^{+} excited state of ^{22}Al. Our results, while supporting the proton-halo structure in ^{22}Al, might provide another means to identify halo nuclei.

Abstract
PURPOSE Management of soft tissue and bone sarcoma presents many challenges, both diagnostically and therapeutically, and requires multidisciplinary collaboration; however, such collaboration is often challenging to establish, especially in the community setting. We share our experiences of a virtual multidisciplinary sarcoma case conference (VMSCC). METHODS We conducted retrospective review of the VMSCC data-initially via Webex, now Microsoft Teams-and the surveys of referring physicians to understand the feasibility and value of the VMSCC. RESULTS The VMSCC was established in March 2013 in Kaiser Permanente Northern California with consistent participation of the Departments of Musculoskeletal Oncology (orthopedic oncology), Musculoskeletal Radiology, Pathology, Medical Oncology, Radiation Oncology, Nuclear Medicine, Surgical Oncology, and Genetics. Pediatric Oncology participated ad hoc when pediatric sarcoma cases were presented. Referrals were from multiple specialties and regions, including the Kaiser Permanente Mid-Atlantic and Hawaii regions. From March 2013 to December 2019, 1,585 cases were reviewed encompassing 36 histologic types. More than 300 cases were reviewed per year from 2017 to 2019. Survey results of referring physicians demonstrate that the VMSCC enhanced the confidence of treating physicians, and its recommendations frequently led to treatment changes. CONCLUSION Establishing a valuable community-based VMSCC is feasible. VMSCC recommendations frequently led to treatment changes and improved the confidence of treating physicians.

Abstract
OBJECTIVE To investigate the regulatory effects of the Toll-like receptor 4 (TLR4) and the nuclear factor kappa-light-chain-enhancer of the activated B cells (NF-κB) on primary biliary cholangitis (PBC) and to analyze the possible mechanisms. MATERIALS AND METHODS A total of 24 C57BL/6 mice were randomly divided into M group (n=12, intraperitoneally injected with polyinosinic acid-polycytidine acid (PolyI:C) for 12 consecutive weeks, 2 times/week) and C group (n=12, intraperitoneally injected with the same volume of normal saline). After 12 weeks, the mice were sacrificed to collect liver tissues. Then, an enzyme-linked immunosorbent assay (ELISA) kit was used to detect the content of interleukin-6 (IL-6), IL-10, and tumor necrosis factor-alpha (TNF-α) in liver tissues. Hematoxylin-eosin (HE) staining assay was performed to observe the pathological changes of liver tissues, and measure the levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in peripheral blood of mice. Terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate-biotin nick end-labeling (TUNEL) staining was applied to determine cell apoptosis in liver tissues. The relative messenger ribonucleic acid (mRNA) expression levels of TLR4 and NF-κB in liver tissues were detected by quantitative Polymerase Chain Reaction (qPCR). Western blotting was adopted to measure the protein expressions of TLR4, NF-κB, myeloid differentiation factor 88 (MyD88), B-cell lymphoma 2 (Bcl-2)/Bcl-2-associated X protein (Bax), and Caspase-3. RESULTS Compared with that in C group, the content of IL-6 and TNF-α in liver tissues in M group was significantly increased (p<0.01), but the level of IL-10 was statistically downregulated (p<0.01). According to HE staining, liver damage of mice in M group was evidently severer than that in C group, and the levels of ALT and AST in M group were significantly higher than those in C group (p<0.01). The amount of TUNEL-positive cells in liver tissues in M group was significantly greater than that in C group (p<0.01). The levels of TLR4 and NF-κB mRNA in liver tissues from M group were significantly elevated in comparison with the C group (p<0.01). Compared with those in C group, the expressions of TLR4, NF-κB, MyD88, and Caspase-3 proteins in M group showed statistical increases in liver tissues (p<0.01), whereas that of Bcl-2/Bax was significantly declined (p<0.01). CONCLUSIONS PBC activates the TLR4/MyD88/NF-κB signaling pathway, induces the release of inflammatory factors and produces a large number of apoptotic proteins, which results in liver damage and cell apoptosis in mice.

Abstract
e23556 Background: Synovial sarcoma is an aggressive soft tissue sarcoma that predominantly affects young patients with high rate of relapse and mortality. Systemic study of patients’ presenting symptoms and possible delay of seeking medical attention is lacking. Methods: We retrospectively reviewed the electronic records of all patients diagnosed with synovial sarcoma from 2005 to 2016 within Kaiser Permanente Northern California to identify the pattern of presenting symptoms and its correlation with outcomes. Results: Of the 77 patients with synovial sarcoma, 64 had early stage disease and 13 had metastatic disease at diagnosis, with median age at diagnosis of 47 years. Anatomically, 48 patients had primary disease at the extremity, 12 trunk, and 17 visceral. Median duration of follow up is 40 months. The median time from symptom to first medical appointment (TTM) is 3 months (range 0.1 to 180 months). Nine out of 13 patients who presented with metastatic disease were visceral primary. For the 60 patients with an extremity/trunk primary, patients who presented with pain without a palpable mass had a median duration of TTM of 12 months, compared to the TTM of 3 months for patients who presented with a palpable mass. The relapse rate (RR) and disease-free survival (DFS) for patients with an extremity/trunk primary who presented with pain but without a palpable mass were significantly worse when compared to patients who presented with a palpable mass (RR 50% vs. 26.5%, and DFS 27 vs. 42.5 months, p < 0.005). TTM was inversely correlated with DFS for the 64 cases with early stage disease and for the 60 cases with extremity/trunk primary (p < 0.00000001). Of the 11 patients with a foot primary, a similar pattern of TTM and DFS was also observed. Conclusions: Patients with synovial sarcoma who presented with pain but without a palpable mass had longer TTM, worse DFS and higher RR compared to patients who presented with a palpable mass. Longer TTM was associated with worse DFS.

Abstract
e19185 Background: The importance of NGS testing to help guide oncologic therapy decisions has grown over time, presenting a unique challenge for community oncologists to properly translate the NGS test results to treatment (Tx) recommendations for patients. Kaiser Permanente Northern California (KPNC) is a large, integrated health care system providing comprehensive primary and specialty care to 4.4 million members, with over 4000 patients (pts) diagnosed with advanced cancer each year. NGS testing at KPNC is performed in a collaboration with Strata Oncology, that provides systematized comprehensive NGS testing (StrataNGS) paired with a portfolio of genomically guided clinical trials. Methods: KPNC has established workflows for upfront empiric review of all NGS results by our KPNC Genomic Oncology Committee (GOC), that includes representatives from medical oncology subspecialists, genetics, pathology, and clinical trials. KPNC GOC reviews all StrataNGS test results in our KPNC network to identify patients that might benefit from either a clinical trial, appropriate on or off-label drug options and/or genetic counseling. In addition, GOC conducts an in-depth case review per request of the treating oncologist. A study nurse pre-screens all pts whose results match to a trial for eligibility. Results: The numbers of pts tested with StrataNGS has increased over time with around 300 pts tested monthly and 4,977 NGS tests performed since Nov 2017. Median age was 65.2 (Range 18.5-96.0). About 42.4% of Pts were non-white. Approximately, 39% of Pts had an actionable mutation including 21.7% eligible for a promising in or out of network trial. 1.6% and 10.9% pts were potentially eligible for off- or on-label approved drugs, respectively. 4.9% were recommended to receive genetic counseling. The 3 most frequently sequenced cancers were: lung, colon and breast. Conclusions: KPNC is providing systematic subspecialty review and management of NGS results for pts in a community setting. Our approach has allowed for greater adoption of routine NGS testing, especially for rare cancer types with less effective standard Tx options available. This model also helps accrual to genomic-based drug trials that have been a challenge for the field. Workflows to streamline automated centralized acquisition of prior Tx history and analysis of response to therapy are in development.
