Abstract
Rheumatic mitral stenosis is still common in sub-Saharan Africa. The aim of this study was to evaluate the clinical and echocardiographic contraindications to the realization of percutaneous mitral commissurotomy (PMC) in Abidjan Heart Institute. We conducted a prospective, transversal and analytical study in the Exploration Unit from March 30, 2017 to March 30, 2018. Mitral stenosis was severe with an average anatomical surface area of 0.87cm2, an average gradient of 13.7 mmHg and an upstream repercussion (dilatation of the left atrium (78 ml/m2); moderate dilatation of the right atrium (22.3 cm2) and average pulmonary arterial hypertension (PAH) of 55 mmHg). The main clinical contraindications were a history of rest dyspnoea at 66.7%, permanent atrial fibrillation at 53.3 % and clinical manifestations of severe PAH in 40 %. Unfavourable anatomy (95.7 %) evaluated by scores of Wilkins, Cormier and especially Echoscore revisited; bicommissural fusion (95.7 %) and severe aortic valvulopathy (31.1%) were the main barriers in transthoracic echocardiography. In multivariate analysis after linear regression, valvular anatomy, as assessed by the various scores, was significantly related to low socioeconomic status (p=0.018), level of education (p=0.04), severity of mitral stenosis evaluated by the mean gradient (p=0.033) and the impact on the left atrium (p=0.015). Mitral stenosis presents several clinical and echocardiographic contraindications. Adverse anatomy is the main obstacle and is related to low socio-economic status, educational level and severity of stenosis.

Abstract
Resistance to radiotherapy is frequently encountered in clinic, leading to poor prognosis of cancer patients. Long noncoding RNAs (lncRNAs) play important roles in the development of radioresistance due to their functions in regulating the expression of target genes at both transcriptional and posttranscriptional levels. Exploring key lncRNAs and elucidating the mechanisms contributing to radioresistance are crucial for the development of effective strategies to reverse radioresistance, which however remains challenging. Here, actin filament-associated protein 1 antisense RNA1 (lncAFAP1-AS1) is identified as a key factor in inducing radioresistance of triple-negative breast cancer (TNBC) via activating the Wnt/β-catenin signaling pathway. Considering the generation of a high concentration of reduction agent glutathione (GSH) under radiation, a reduction-responsive nanoparticle (NP) platform is engineered for effective lncAFAP1-AS1 siRNA (siAFAP1-AS1) delivery. Systemic delivery of siAFAP1-AS1 with the reduction-responsive NPs can synergistically reverse radioresistance by silencing lncAFAP1-AS1 expression and scavenging intracellular GSH, leading to a dramatically enhanced radiotherapy effect in both xenograft and metastatic TNBC tumor models. The findings indicate that lncAFAP1-AS1 can be used to predict the outcome of TNBC radiotherapy and combination of systemic siAFAP1-AS1 delivery with radiotherapy can be applied for the treatment of recurrent TNBC patients.

Abstract
Cinnamon essential oil (CEO) was extracted by three different methods: steam distillation (SD), ultrasound-assisted steam distillation (UASD) and microwave-assisted steam distillation (MASD). The volatiles in CEO were separated and identified by gas chromatography–mass spectrometry (GC-MS), and the differences in volatiles among the three different methods were further analyzed through principal component analysis. The results showed that 36 individual volatile components were present in the CEO from the three different methods. In general, the numbers of aldehydes, esters, alcohols, terpenes, aromatics and ketones were 6, 3, 7, 17, 2, and 1, respectively. The most abundant volatile component was determined to be cinnamic aldehyde. The content of total cinnamic aldehydes, which determines the price of CEO, was the highest among the three methods in the UASD sample (85.633%). Moreover, the highest yield (8.33‰) of essential oil was extracted by the UASD method. Therefore, UASD was the best way for CEO extraction in this research and was recommended for future industrial applications.

Abstract
BACKGROUND The usefulness of the combined assessment of HbA1c and plasma glucose (PG) in acute myocardial infarction (AMI) in non-diabetic patients remains unclear. PURPOSE In a large observational study, we aimed to identify the prognostic values of these biomarkers regarding one-year all-cause mortality in non-diabetic patients after AMI. METHODS From the "obseRvatoire des Infarctus de Côte d'Or" (RICO) survey database, we included all consecutive non-diabetic patients with AMI (n=6617) from May 2001 to December 2016. Exclusion criteria were: admission known or unknown diabetes, in-hospital death. The primary endpoint was all-cause one-year mortality. The secondary endpoints were: MACE, infarct size, LVEF<40% and GRACE risk score. Cut-off levels (high/low) were determined by ROC curve analysis for the prediction of one-year death (HbA1c 5.9% and PG 131mg/dL) to set up 4 groups: low HbA1c/low glucose (n=3158), low HbA1c/high glucose (n=1264), high HbA1c/low glucose (n=1378) and high HbA1c/high glucose (n=817). RESULTS Elevation of PG was associated with elevated rate of LVEF<40%, STEMI, anterior wall location, DFG<60mL/min/m2 and higher troponin Ic pic (all P<0.001); HbA1c>5.9% was associated with elevated rate of CRP>3mg/L (P<0.001); high HbA1c and high PG together were associated with higher rate of MACE (P<0.001). By multivariate logistic regression analysis, elevated admission PG remained a strong predictor of one-year all-cause [OR (95%CI): 1.64 (1.31-2.05)] mortality and cardiovascular mortality [OR (95%CI): 1.75 (1.33-2.31)], beyond GRACE score [OR (95%CI): 1.03 (1.03-1.04)], as well as elevated HbA1c [OR (95%CI): 1.43 (1.15-1.78) and OR (95%CI): 1.83 (1.39-2.41) respectively]. CONCLUSIONS Admission PG and HbA1c had strong independent predictive value regarding one-year all-cause mortality in our non-diabetic patients with AMI. These biomarkers could be useful to identify the most-at-risk patients after AMI in order to reduce residual risk in this target population.

Abstract
Purpose To assess the efficacy and safety of cyclin-dependent kinases 4 and 6 inhibitors (CDKi) combined with endocrine therapy (ET) in women with hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative advanced breast cancer (ABC) and compare the efficacy of different CDKi (palbociclib, ribociclib, or abemaciclib). Materials and Methods This study based on randomized Phase 2 or 3 trials of CDKi plus ET compared with placebo plus ET for women with HR+/HER2−ABC and identify relevant randomized clinical trials (RCTs) published prior to February 2020. The primary endpoint was progression-free survival (PFS), the secondary endpoints included overall survival (OS), objective response rate (ORR), clinical benefit response (CBR) and safety. The PROSPERO registry number is 42018081105. Results The results from eight trials including 4580 participants were pooled. Evidence indicated that the PFS of CDKi group was significantly prolonged (hazard ratio [HR] 0.55, 95% confidence interval [CI] 0.50–0.60, P < 0.01) compared with placebo group. The ORR and CBR were better (risk ratio [RR] 1.47, 95% CI 1.30–1.67, P < 0.01; 1.24, 95% CI 1.15–1.35, P < 0.01) in the CDKi group. The OS of CDKi group (HR 0.75, 95% CI 0.67–0.85, P < 0.01) was significantly longer than ET alone. Subgroup analyses confirmed that the benefit was consistent across most subgroups. Subgroup analyses showed no statistically significant difference of PFS among three CDKi: palbociclib vs ribociclib (HR 0.55, 95% CI 0.49–0.60, P = 0.34), palbociclib vs abemaciclib (HR 0.53, 95% CI, 0.47–0.59, P = 0.61), and ribociclib vs abemaciclib (HR 0.56, 95% CI, 0.51–0.62, P = 0.72). Treatment-related grade 3 or 4 hematologic adverse events (AEs) were more frequently in CDKi group. Conclusion CDKi combined with ET can significantly prolong PFS and improve the ORR, CBR and OS in patients with HR+/HER2− ABC. However, the advantage of different CDKi has not been established.

Abstract
e17040 Background: PD-1/PD-L1 blockade significantly improved survival for bladder cancer. PD-L1 expression might not be an ideal marker for patient selection in isolation. Several studies demonstrated that alternative markers such as NLR, a biomarker of systemic inflammation response to therapy, correlated with outcomes in a variety of cancers including bladder cancer, might be a predictor for patient selection and the response to immunotherapy. However, no reporters have been made combination of NLR and PD-L1 in predicting prognosis in bladder cancer. Methods: Suitable tissue of 100 FFPE blocks of bladder cancer patients treated in Sun Yat-Sen Memorial Hospital Sun Yat-sen University were stained with PD-L1 antibody. Clinicopathological data and pretreatment complete blood count were retrospectively collected. All patients were classified into high NLR group and low NLR group at cut-off 3.0. Kaplan-Meier and Cox proportional hazard models analyses were used to assessed the predictor of combined PD-L1/NLR for disease-free survival (DFS) and overall survival (OS). Results: Patients were mostly male (79%) with high grade () lymph node positive (21%), T3-4 (33%) . The positivity of PD-L1 expression was 22% (22/100) at cut-off 1%. Univariate analysis showed that PD-L1 expression was positively associated with larger tumor size, higher grade, positive lymph node metastases. Median DFS and OS were 35 months and 37 months, respectively. Both PD-L1 expression and NLR were associated with DFS and OS. COX analysis model showed that PD-L1 and NLR were independent prognostic factors for tumor prognosis. Of interest, when patients were divided in two groups based on PD-L1/NLR: patients with PD-L1+/high NLR as group 1 and other patients as group 2, group1 had significantly shorter DFS and OS (DFS, X2 = 4.146, P = 0.042; OS, X2 = 10.274, P = 0.001). COX proportional hazards regression models indicated that PD-L1+/high NLR was correlated with a significantly shorter DFS and OS (DFS, hazard ration [ HR] = 2.572, P = 0.05; OS, HR = 3.811, P = 0.003). Conclusions: The study indicated that combined use of PD-L-1/ NLR as predictive biomarker for survival. This feasible panel may be optional maker applied to select patients for immunotherapy.

Abstract
e21044 Background: The purpose of this study was to investigate whether the combined radiomic model based on tumor-associated and margin-related (5mm) radiomic features can effectively improve prediction performance of distinguishing precancerous lesions from early stage lung adenocarcinoma. Methods: 264 patients underwent preoperative chest CT in Guangdong Provincial People’s hospital from March 1, 2015 to December 31,2019 were sorted by three cohorts. All lesions were pathologically confirmed as precancerous lesions or Stage I lung adenocarcinoma and a total of 861 analyzable radiomic features were extracted from two segmented lesions including pulmonary lesions and margins, using PyRadiomics by two senior radiologists. In training cohort, 145 patients (70%) are selected randomly from the single-nodular patients (N = 207). As for the validation cohorts, the models were validated using the resting 62 patients from single-nodular cohort and multi-nodular cohort (n = 57) respectively. Least Absolute Shrinkage and Selector Operation and Support Vector Machine-Recursive Feature Elimination were used for feature selection. ROC analysis and AUC were used to evaluate the performance of three models which were developed by multiple logistic regression on distinguishing the precancerous lesions from early stage lung adenocarcinoma. Results: Selected features from pulmonary lesions and pericarcinous tissue were developed into two independent radiomic models and a combined model. Margin-related radiomic model performs well in three validation cohorts. The AUC Brock of single-nodular cohort in training cohort was 0.912 (95% CI: 0.876-0.948), while in single-nodular validation cohort was 0.93 (95% CI: 0.862-0.966). Multi-nodular validation cohort in this model shows an AUC of 0.891 (95% CI = 0.824–0.943). Comparing combined model and tumor-associated radiomic model, it is found that the AUC of combined model was improved from 0.865 (95% CI: 0.767-0.963) to 0.94 (95% CI: 0.767-0.963) for single-nodular validation cohort. Respectively, this combined model also performs well in multi-nodular validation cohort. Conclusions: This study demonstrated the potential of margin-related radiomic features based on preoperative CT scans to distinguish precancerous lesions from early stage lung adenocarcinoma. The constructed radiomic model provided an easy-to-use, preoperative tool for surgeons to develop accurate therapeutic strategies for multi-nodular patients.

Abstract
e12528 Background: We previously reported a Chinese version of 21-genes Recurrence Score (RS) provides reduction chemotherapy prescription in patients with ER-Positive/HER2-Negative node negative breast cancer, while Oncotype Dx was hardly to be reached. However, the impact on clinical outcome was not mentioned. Herein, we explored whether this 21-genes recurrence score (RS) impacted on prognosis in patients with this molecular subtype of breast cancer. Methods: From Jan 2013 to Aug 2018, 378 patients with ER-Positive/HER2-Negative early stage breast cancer were enrolled. All patients received a Chinese version of 21-genes RS test, which is a new method using RNA extracted from formalin-fixed paraffin-embedded tissue performed by SurExam Campany, Guangzhou, China. . The RS score for each patient was calculated based on expression level of 21-genes used in a prosperctively defined algorithm and calculate a recurrence score range from 0 to 100 and divided three risk groups according to TAILORs study.Distant metastases-free survival (DMFS) were correlated with the 21-genes RS by Kaplan-Meier (log-rank method), and Cox regression. Multivariable logistic regression was performed to determine factors correlated with RS testing and receipt of a high-risk RS. Results: Median patient age was 46 years (18 to 77 years). The Chinese version of 21-gene RS was generated for 378 patients: 61 (16.1%) low risk ( < 11), 241 (63.8%) intermediate risk (11 to 25), and 76 (20.1%) high risk (≥ 26). At a median follow-up of 40 months, the 4-year-rate of estimated DMFS was 100%, 98.7% and 92.9% in low risk, intermediate risk and high risk groups. Meanwhile, there was no difference in RFS among three risk groups. For all patients, 21-gene RS was associated with DMFS ( P = .021). In multivariable Cox regression models, 21-gene RS was independently prognostic factor of DMFS (hazard ratio, 5.375; 95% CI, 1.00 to 28.84; P = .05). Tumor size (>2cm vs ≤2cm, OR = 2.31, P = .005), high grade ( OR = 2.15, P = .013), ki67 index ( > 14% vs ≤14%, OR = 4.24, P = .002), progesterone receptor expression ( < 20% vs ≥20%, OR = 5.07, P < .001) were predictor of high risk of RS. Conclusions: The Chinese version of 21-genes RS is independently prognostic factor for DMFS patients with ER–positive/HER2-negative node negative breast cancer. Future study was needed to explore the impact of 21 gene RS on long-term prognosis.

Abstract
3563 Background: The early stage breast cancer patients can vary in disease-free survival (DFS), innovative predictors evaluate the prognostic capacity are urgently needed. We aimed to develop and independently validate a radiomics signature based on MRI associated with phenotypes and DFS in patients with breast cancer and to establish a radiomics nomogram that incorporates the radiomics signature and clinicopathological findings using computational algorithms. Methods: In this multicenter, retrospective, cohort study, we analyzed preoperative contrast–enhanced MRI data from the prospective cohort study (n = 123) of patients who had been treated with neoadjuvant chemotherapy in phase 3 trials and independent cohort (n = 438) at the Sun Yat-sen Memorial Hospital as training cohort to develop the radiomic signature, and validated it in validation cohort (Foshan cohort, n = 121; Dongguan cohort, n = 89) between November 17, 2011, and September 21, 2019, and validated in TGCA cohort (n = 84). Machine-learning algorithm to identify robust imaging subtypes and evaluated their clinical and biologic relevance. A nomogram combining the radiomic signature and clinicopathological findings to predict individual survival based on Cox regression model. The primary endpoint was disease-free survival (DFS). This study is registered with ClinicalTrials.gov, number NCT04003558, and Chinese Clinical Trail Registry, number ChiCTR1900024020. Results: A total of 855 breast cancer patients were included. Radiomics signature was generated to classify patients into high-risk and low-risk groups in the Guangzhou training cohort. Patients with low-risk scores in the training cohort had higher DFS (hazard ratio [HR] 0.55, 95% CI 0.31 to 0.99; P= 0.045) than patients with high-risk scores, and validated in in validation cohort (HR 0.14, 95% CI 0.03 to 0.62; P= 0.003). The nomogram combined radiomics score with clinicopathological factors could accurately predict DFS benefits in training cohort (C-index = 0.83; AUC, 1, 2, 3-year were 0.80, 0.85, 0.82, respectively) and validated in validation cohorts. Conclusions: The radiomics signature are significantly associated with the DFS in patients with breast cancer. Combining the radiomics nomogram improved individualized DFS pretiction. Clinical trial information: NCT04003558 .

Abstract
Objective: To investigate the influence of the prevalence and co-prevalence of risk factors for metabolic syndrome on the scores of different levels of metabolic syndrome in people receiving physical examination in Urumqi. Methods: Using the 2017 Xinjiang Health Examination Database, a total of 175 927 people from 7 districts and 1 county in Urumqi were selected as subjects. Face-to-face survey and body measurements were used to collect cardiovascular risk factors and metabolic syndrome scores. Metabolic syndrome scores were used. For the 0-5 points at 6 levels, χ(2), χ(2) trend test, correlation analysis of ordered variable Kendall's tau-b, and logistic regression analysis of ordered results were used to analyze the influence of prevalence and co-prevalence of behavioral risk factors on the MS scores. Results: The percentages of 6 metabolic syndrome scores in the sample population were 23.82%, 27.87%, 22.41%, 16.03%, 8.02%, and 1.85%, respectively. The scores of metabolic syndrome were different in different age groups, ethnic groups, groups with different drinking rates, and groups with different dietary types, with the differences all significant (P<0.05).The MS score in men increased with the increase of oil/salt rate and excessive drinking rate (P<0.01). The score in women increased with the increase of the current smoking rate, oil/salt rate, and increased with the decrease of physical activity (P≤0.01). There was no significant difference in the distribution of regular drinking rates between different score groups (P>0.05). The scores of metabolic syndrome increased with the increase of risk factors (P<0.05). Ordered results logistic analysis found that in the men with ≥3 risk factors and the metabolic syndrome score was 1.15 (1.06-1.26) times higher than that in the men without risk factor, as well as in women with 2 risk factors and≥3 risk factors. The metabolic syndrome scores were 1.38 (1.22-1.55), 2.02 (1.53-2.66) times higher than those in the women without risk factors. Conclusions: The physical examination group in Urumqi, the more the metabolic syndrome disease behavior risk factors clustered, the higher the metabolic syndrome score was. Therefore, comprehensive intervention measures should be taken to control the different forms of metabolic syndrome to prevent the occurrence and progress of the disease.

Abstract
OBJECTIVE To evaluate a reverse transcription loop-mediated isothermal amplification (RT-LAMP) assay for detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and compare it with RT-PCR. METHODS We designed primers specific to the orf1ab and S genes of SARS-CoV-2. Total viral RNA was extracted using the QIAamp Viral RNA Mini Kit. We optimized the RT-LAMP assay, and evaluated it for its sensitivity and specificity of detection using real-time turbidity monitoring and visual observation. RESULTS The primer sets orf1ab-4 and S-123 amplified the genes in the shortest times, the mean (±SD) times were 18 ± 1.32 min and 20 ± 1.80 min, respectively, and 63°C was the optimum reaction temperature. The sensitivities were 2 × 101 copies and 2 × 102 copies per reaction with primer sets orf1ab-4 and S-123, respectively. This assay showed no cross-reactivity with 60 other respiratory pathogens. To describe the availability of this method in clinical diagnosis, we collected 130 specimens from patients with clinically suspected SARS-CoV-2 infection. Among them, 58 were confirmed to be positive and 72 were negative by RT-LAMP. The sensitivity was 100% (95% CI 92.3%-100%), specificity 100% (95% CI 93.7%-100%). This assay detected SARS-CoV-2 in a mean (±SD) time of 26.28 ± 4.48 min and the results can be identified with visual observation. CONCLUSION These results demonstrate that we developed a rapid, simple, specific and sensitive RT-LAMP assay for SARS-CoV-2 detection among clinical samples. It will be a powerful tool for SARS-CoV-2 identification, and for monitoring suspected patients, close contacts and high-risk groups.

Abstract
IMPORTANCE Long noncoding RNAs (lncRNAs) are involved in innate and adaptive immunity in cancer by mediating the functional state of immunologic cells, pathways, and genes. However, whether lncRNAs are associated with immune molecular classification and clinical outcomes of cancer immunotherapy is largely unknown. OBJECTIVES To explore lncRNA-based immune subtypes associated with survival and response to cancer immunotherapy and to present a novel lncRNA score for immunotherapy prediction using computational algorithms. DESIGN, SETTING, AND PARTICIPANTS In this cohort study, an individual patient analysis based on a phase 2, single-arm clinical trial and multicohort was performed from June 25 through September 30, 2019. Data are from the phase 2 IMvigor210 trial and from The Cancer Genome Atlas (TCGA). The study analyzed lncRNA and genomic data of 348 patients with bladder cancer from the IMvigor210 trial and 71 patients with melanoma from TCGA who were treated with immunotherapy. In addition, a pancancer multicohort that included 2951 patients was obtained from TCGA. MAIN OUTCOMES AND MEASURES The primary end point was overall survival (OS). RESULTS Among 348 patients from the IMvigor210 trial (272 [78.2%] male) and 71 patients with melanoma from TCGA (mean [SD] age, 58.3 [13.4] years; 37 [52.1%] female), 4 distinct classes with statistically significant differences in OS (median months, not reached vs 9.6 vs 8.1 vs 6.7 months; P = .002) were identified. The greatest OS benefit was obtained in the immune-active class, as characterized by the immune-functional lncRNA signature and high CTL infiltration. Patients with low vs high lncRNA scores had statistically significantly longer OS (hazard ratio, 0.32; 95% CI, 0.24-0.42; P < .001) in the IMvigor210 trial and across various cancer types. The lncRNA score was associated with immunotherapeutic OS benefit in the IMvigor210 trial cohort (area under the curve [AUC], 0.79 at 12 months and 0.77 at 20 months) and in TCGA melanoma cohort (AUC, 0.87 at 24 months), superior tumor alteration burden, programmed cell death ligand 1 (PD-L1) expression, and cytotoxic T-lymphocyte (CTL) infiltration. Addition of the lncRNA score to the combination of tumor alteration burden, PD-L1 expression, and CTL infiltration to build a novel multiomics algorithm correlated more strongly with OS in the IMvigor210 trial cohort (AUC, 0.81 at 12 months and 0.80 at 20 months). CONCLUSIONS AND RELEVANCE This study identifies novel lncRNA-based immune classes in cancer immunotherapy and recommends immunotherapy for patients in the immune-active class. In addition, the study recommends that the lncRNA score should be integrated into multiomic panels for precision immunotherapy.

Abstract
Background The prognosis of breast phyllodes tumors (PTs) largely depending on the pathological grading, which lacks objectivity. This study aimed to develop a nomogram based on clinicopathological features to evaluate the recurrence probability of PTs following surgery. Methods Data from 334 patients with breast PTs, who underwent surgical treatment at Sun Yat-sen Memorial Hospital from January 2005 to December 2014, were used to develop a prediction model. Additionally, data of 36 patients from Peking University Shenzhen Hospital (cohort 1) and data of 140 patients from Sun Yat-sen University Cancer Center (cohort 2) during the same period were used to validate the model. The medical records and tumor slides were retrospectively reviewed. The log-rank and Cox regression tests were used to develop a clinical prediction model of breast PTs. All statistical analyses were performed using R and STATA. Results Of all 334 patients included in the primary cohort, 224 had benign, 91 had borderline, and 19 had malignant tumors. The 1-, 3-, and 5-year recurrence-free survival was 98.5%, 97.9%, and 96.8%, respectively. Ultrasound-guided vacuum-assisted biopsy (UGVAB) is a non-inferior treatment application in benign PTs compared with open surgery [hazard ratio (HR), 2.38; 95% confidence interval (CI), 0.59–9.58]. Width of surgical margin, mitoses, and tumor border were identified as independent risk factors for breast PTs. A nomogram was developed based on these three variables. The C-index of internal and external validation was 0.71, 0.67 (cohort 1) and 0.73 (cohort 2), respectively. Conclusions The study model presented more concise and objective variables to evaluate the recurrence-free survival of patients after surgery, which can help deciding whether to do a re-excision or “wait and watch”.

Abstract
Background Current guidelines lack recommendations for the use of immunotherapy and immune-related biomarkers for hepatocellular carcinoma (HCC). We aim to provide reliable evidence of the association of survival with HCC immunotherapy and to demonstrate that genomic mutation signature could be an effective biomarker to predict immunotherapy efficacy of HCC patients. Methods We conducted a meta-analysis of 17 randomized trials with 2055 patients and an individual patient-level analysis of 31 patients. Trial data were identified in PubMed, EMBASE and Cochrane Central library, and individual patient data were obtained from the cBioPortal database. Overall survival (OS) and progression-free survival (PFS) were assessed with the hazard ratio (HR) and 95% CI. This study is registered with PROSPERO, number CRD42018083991. Results The meta-analysis showed that compared to conventional therapy, immunotherapy resulted in prolonged OS (HR =0.65, P<0.0001, high quality) and PFS (HR =0.81, P<0.0001, high quality); the benefits were observed for cellular immunotherapy, tumor vaccine, and cytokine immunotherapy. Findings were robust to subgroup and trial sequential analyses. In the individual patient-level analysis of patients treated with immune checkpoint inhibitor, mutations in TERT, CTNNB1, BRD4, or MLL, and co-mutations in TP53 and TERT or BRD4 were associated with significantly worse survival. These oncogenes were used to develop a novel integrated mutation risk score, which exhibited better utility in predicting survival than the tumor mutation burden (TMB). Patients with low- versus high- mutation risk score had longer OS (HR =0.18, P=0.02) and PFS (HR =0.33, P=0.018). A nomogram comprising the mutation risk score and essential clinical factors further improved the predictive accuracy (AUC =0.840 for both 1- and 2-year OS). Conclusions Immunotherapy showed longer OS and PFS than conventional therapy among HCC patients, especially patients with a low mutation risk score. The nomogram based on genomic and clinical characteristics is effective in predicting survival of HCC patients undergoing immune checkpoint inhibitor.

Abstract
Abstract
Background: Axillary lymph node metastasis is a vital factor of prognosis in patients with invasive breast cancer. However, sensitivity and noninvasive for prediction of lymph node metastasis and survival after neoadjuvant chemotherapy is limited. This study aims to develop radiomics combining multi-parametric MRI before and after neoadjuvant chemotherapy to predict axillary lymph node metastasis and prognosis, as well as investigate the relationship between the radiomics and tumor microenvironment in invasive breast- cancer.
Methods: RBC-02 is a multicenter, ambispective cohort study proposes to build a clinical predictive model to predict axillary lymph node metastasis and prognosis in invasive-breast- cancer patients who received neoadjuvant chemotherapy. Patients are recruited from Sun Yat-sen Memorial Hospital of Sun Yat-sen University (training cohort), Sun Yat-sen University Cancer Center (validation cohort), and Tungwah hospital of Sun Yat-sen University (validation cohort) in China. Invasive breast cancer patients undergo multi-parametric MRI at baseline, then undergo multi-parametric MRI after received neoadjuvant chemotherapy for at least 4 cycles as planned. After the surgery, responses to neoadjuvant chemotherapy are determined according to the histopathologically examination of the surgically resected specimens. The model is built based on breast MRI signatures extracted and analyzed via deep machine- learning algorithm methods. The correlation between radiomics features and tumor microenvironment is also planned to investigate. Decision curve analysis was performed with the combined training and validation set to estimate the clinical usefulness of the radiomics nomogram, which is built with a multivariate logistic regression model. The primary endpoint is disease-free survival. Secondary endpoints include pathological complete response, pathological axillary lymph node status, and overall survival. The trial is registered with ClinicalTrials.gov, number NCT04004559, and Chinese Clinical Trail Registry, number ChiCTR1900024113.

Abstract
OBJECTIVE To explore the effects of Mg2+ on the expression of osteoarthritic markers in human cartilage and synovium tissue explants. To investigate the therapeutic effect of intra-articular injection of Mg2+ in an established rat OA (Osteoarthritis) model of anterior cruciate ligament transection with partial medial meniscectomy (ACLT + PMM). DESIGN Human cartilage and synovium explants were collected from total knee replacement surgeries and incubated with MgCl2 (20 mmol/L) in vitro. A rat OA model was established by ACLT + PMM surgery in 450-500 g male Sprague Dawley (SD) rats. To select the optimal dose, intra-articular injections of MgCl2 (0.05, 0.5, 5 mol/L) were performed at 4 weeks after the surgery every 3 days for 2 weeks. The effect of optimized MgCl2 was further determined by histology, immunohistochemistry, and quantitative real-time polymerase chain reaction. RESULTS The expressions of osteoarthritic markers in human cartilage and synovium explants were inhibited by Mg2+in vitro. Immunohistochemical analysis further suggested the inhibitory effects of Mg2+ on the expression of MMP-13 and IL-6 in the human tissue explants. Cartilage degeneration and synovitis in ACLT + PMM rats were significantly improved by intra-articular injections of Mg2+ (0.5 mol/L). Immunohistochemical analysis also showed the regulatory effects of Mg2+ on osteoarthritic markers in both cartilage and synovium in rats, consistent with in vitro results. CONCLUSION Intra-articular injections of Mg2+ at 0.5 mol/L attenuate the progression of OA in the ACLT + PMM rat model. Such effect was at least in part explained by the promotion of cartilage matrix synthesis and the suppression of synovial inflammation.

Abstract
OBJECTIVE MicroRNAs (miRNAs) are now recognized as important regulators of gene expression. The aim of the study was to investigate the role of miR-146b-5p in the TLR4 pathway and provide the basis for the treatment of lupus nephritis. MATERIALS AND METHODS The glomerular mesangial cells were cultured in vitro and divided into 3 groups: control group, a group of miR-146b-5p mimic added, and a group of miR-146b-5p inhibitor added. The levels of IL-6 and IL-8 in the cell culture supernatant of the three groups were detected by ELISA. The cell proliferation was detected by MTT. The expressions of MiR-146b-5p and TLR4 pathway-associated factor TRAF6 were detected by RT- PCR. The expression of TRAF6 and IRAK1 protein was detected by Western blot. RESULTS The overexpression of miR-146b-5p could reduce the level of IL6 and IL8 in cell culture and inhibit glomerular mesangial cell proliferation in some degree. Also, the overexpression of miR-146b-5p could inhibit the expressions of TLR4 pathway-associated factor TRAF6 and IRAK1mRNA, and the expressions of TRAF6 and IRAK1 protein. CONCLUSIONS MiR-146b-5p attenuated the inflammatory response of glomerular mesangial cells by inhibiting the expressions levels of TRAF6 and IRAK1 in lupus nephritis.

Abstract
OBJECTIVE Chronic inflammation is recognized as a risk factor for colorectal cancer (CRC) development. Baicalin (BI), a major constituent in an anti-inflammatory herb Scutellaria baicalensis, can be biotransformed into baicalein (BE) by the intestinal microbiota. We evaluated the anti-inflammation and anti-CRC effects of the metabolite BE. METHODS The in vitro biotransformation by human intestinal microbiota from BI into BE has been determined with HPLC. Using a gut-specific ApcMin/+ mouse model, the effects of oral BE on the life span, organ index, and tumor multiplicity were evaluated. The expressions of inflammatory cytokines were determined using ELISA. To verify the in vivo data, the anti-inflammatory and antiproliferative effects of BE were determined with an in vitro cell model. RESULTS HPLC analysis showed that BI was quickly transformed into BE by the intestinal microbiota. Oral BE (30 mg/kg/day) significantly increased the life span, from 125.2 to 218.4 days (P < 0.01%). BE treatment also decreased intestine index and increased spleen index. Compared with the model group, following BE treatment, tumor numbers were significantly reduced in the small intestine and colon (P < 0.01, P < 0.05, respectively). In the gut tissues, BE treatment significantly reduced inflammatory cytokine levels such as IL-1β, IL-2, IL-6, IL-10, G-CSF, and GM-CSF. In vitro data supported our in vivo results that the anti-CRC effects of BE were via the inhibition of gut inflammation and induction of cancer cell death. CONCLUSION Our results suggest that the parent compound BI can be quickly converted into its microbial metabolite BE, which has stronger bioactive effects than BI. Baicalein is an active chemopreventive metabolite for inflammatory associated CRC.

Abstract
Abstract
Aim
Individuals with heterozygous familial hypercholesterolemia (FH) are at high risk of early myocardial infarction (MI). However, coronary artery disease (CAD) burden of FH remains not well described. From a large database of a regional registry of acute MI, we aimed to address prevalence of FH and severity of CAD.
Methods
Consecutive patients hospitalized with MI in a multicentre database from 2001–2017 were considered. An algorithm, adapted from Dutch Lipid Clinic Network criteria, was built upon 4 variables (LDL-cholesterol (LDL-C) and lipid lowering agents, premature and family history of CAD) to identify FH probabilities.
Results
Among the 11624 patients included in the survey, 249 (2.1%) had probable/definite FH (score ≥6), and 2405 (20.7%) had possible FH (score 3–5). When compared with patients without FH (score 0–2), FH patients (score ≥6) were 20y younger (51 (46–57) vs 71 (61–80) y, p<0.001), with a lower rate of hypertension (47 vs 59%, p<0.001), diabetes (17 vs 25%, p<0.001) and prior stroke (4 vs 8%, p=0.016), but a higher prevalence of smokers (56 vs 23%, p<0.001), personal (20 vs 15%, p=0.02) or familial history of CAD (78 vs 18%, p<0.001). Chronic statin treatment was only used in 48% of FH patients and ezetimibe in 8%. After adjustment for age, sex and diabetes, FH patients were characterized by increased extent of CAD (syntax score 11 (4–19) vs 7 (1–13), p<0.001) and multivessel disease (55 vs 40%, p<0.001).
Conclusion
In this large real world population of acute MI, a high prevalence of FH was found. FH patients were characterized by their young age associated with the severity of CAD burden and limited use of preventive lipid lowering therapy.

Abstract
Nanoparticles (NPs) formulated with cationic lipids and/or polymers have shown substantial potential for systemic delivery of RNA therapeutics such as small interfering RNA (siRNA) for the treatment of cancer and other diseases. While both cationic lipids and polymers have demonstrated the promise to facilitate siRNA encapsulation and endosomal escape, they could also hamper cytosolic siRNA release due to charge interaction and induce potential toxicities. Herein, a unique polymer-prodrug hybrid NP platform was developed for multistage siRNA delivery and combination cancer therapy. This NP system is composed of (i) a hydrophilic polyethylene glycol (PEG) shell, (ii) a hydrophobic NP core made with a tumor microenvironment (TME) pH-responsive polymer, and (iii) charge-mediated complexes of siRNA and amphiphilic cationic mitoxantrone (MTO)-based prodrug that are encapsulated in the NP core. After intravenous administration, the long-circulating NPs accumulate in tumor tissues and then rapidly release the siRNA-prodrug complexes via TME pH-mediated NP disassociation for subsequent tissue penetration and cytosolic transport. With the overexpressed esterase in tumor cells to hydrolyze the amphiphilic structure of the prodrug and thereby induce destabilization of the siRNA-prodrug complexes, the therapeutic siRNA and anticancer drug MTO can be efficiently released in the cytoplasm, ultimately leading to the combinational inhibition of tumor growth via concurrent RNAi-mediated gene silencing and MTO-mediated chemotherapy.

Abstract
Background Nasopharyngeal carcinoma (NPC) is a common epithelial carcinoma with high occurrence and metastatic rates in Southern China. To date, the molecular mechanisms of metastasis for NPC remains unclear. The aim of this study was to discover the underlying mechanism of NPC and to elucidate novel genes that may play important roles in NPC progression and metastasis. Methods We carry out mRNA expression profiling, Arraystar Human mRNA Expression Profiling Service Report based on polymerase chain reaction (PCR) using four pairs of tumor tissues and their corresponding benign adjacent tissues from NPC patients. Results We found that 1,787 genes were differentially expressed, among them, 8 genes were identified as highly upregulated in NPC patients. Within these 8 genes, only TSPAN8 was consistently over-expressed in poorly differentiated CNE2 cell line and highly-metastatic subclone S18 cell line. TSPAN8 mRNA and protein levels were increased in primary carcinoma tissues compared to their corresponding adjacent benign tissues. Knockdown of TSPAN8 by siRNA resulted in inhibition of NPC cell migration and invasion, while overexpression of TSPAN8 promoted NPC cell migration, invasion and proliferation. To explore the potential metastasis pathway mechanism for NPC, TSPAN8 were silenced in CNE2 cell. From the Tumor Metastasis Pathway Finder PCR array, knockdown of TSPAN8 led to the down-regulation of IL-1β, which showed the most down-regulation among identified genes. IL-1β is a regulating factor of the Akt/MAPK pathway, which is involved in the cancer cell migration regulation. Furthermore, the down-regulation of TSPAN8 in CNE2 cell was associated with inhibition of the Akt/MAPK pathway. Immunohistochemistry (IHC) indicated that TSPAN8 level was increased in NPC tumors, which was associated with shorter overall survival and metastasis free survival (MFS). Conclusions The data indicated that TSPAN8 acting as a tumor migration marker and may be a prognostic factor or therapeutic target for NPC.

Abstract
BACKGROUND The prognosis of ductal carcinoma in situ (DCIS) is reportedly well. Extremely rare patients with DCIS develop distant breast cancer metastasis without locoregional or contralateral recurrence. This is the first report of multiple bones and sigmoid colon metastases from DCIS after mastectomy. CASE PRESENTATION A 43-year-old woman was diagnosed with DCIS, and she received mastectomy, followed by endocrine therapy and target therapy. During the following-up, convulsions and pain on the legs were complaint. Therefore, Computed Tomography (CT) on bones and positron emission tomography (PET) for whole body were examined in order. Multiple bones and sigmoid colon were under the suspect of metastases, which were then verified by biopsy in the left ilium and colonoscopy respectively. CONCLUSIONS This case reveals the heterogeneous behavior and the potential poor outcome of DCIS, regular examination and surveillance are necessary even though the distant metastasis rate in DCIS is low.

Abstract
The role of long non-coding RNA (lncRNA) in the progression of Nasopharyngeal carcinoma (NPC) has not been fully elucidated. The study was designed to explore the functional role of NKILA, a newly identified lncRNA, in the progression of NPC. We performed a lncRNA expression profile microarray using four NPC and paired para-cancerous tissues. NKILA was identified as a potential functional lncRNA by this lncRNA expression profile. We used 107 paraffin-embedded NPC tissues with different TNM stages to detect the expression of NKILA and analyzed the survival data by Log-rank test and Cox regression. The role of NKILA and its underlying mechanisms in the progression of NPC were evaluated by a series of experiments in vitro and vivo by silencing or expressing NKILA. Compared with control tissues, NKILA expression was identified to be decreased in NPC tissues. Low NKILA expression was correlated with unfavorable clinicopathological features and predicted poor survival outcome in NPC patients. After adjusting for potential confounders, low expression of NKILA was confirmed to be an independent prognostic factor correlated with poor survival outcomes. Furthermore, we found that NKILA overexpression in high-metastatic-potential NPC cells repressed motile behavior and impaired the metastatic capacity in vitro and in vivo. In contrast, RNAi-mediated NKILA depletion increased the invasive motility of cells with lower metastatic potential. Further experiments demonstrated that NKILA regulated the metastasis of NPC through the NF-κB pathway. Taken together, NKILA plays vital roles in the pathogenesis of NPC. The unique histological characteristics of NPC indicate that local inflammation plays a vital role in carcinogenesis of nasopharyngeal carcinoma. NF-κB is a pivotal link between NPC and inflammation. Importantly, NF-κB was found to be overexpressed in nearly all NPC tissues, and inflammatory cytokines have also been observed in NPC tissues. Inflammatory cytokines promote the susceptibility of NPC cells to metastasize via constant NF-κB activation. Here, we found that NKILA, a newly identified lncRNA, is upregulated by inflammatory cytokines and is significantly downregulated in NPC. By a series of in vitro and in vivo experiments, we show that NKILA exerts its effect as a tumor suppressor via inhibiting tumorigenesis and metastasis of NPC. Further studies indicate that NKILA regulates the metastasis of NPC through NF-κB pathway. Our research demonstrates that NKILA plays a critical role in the progression of NPC. These findings are particularly important as they provide new insights into the effects of inflammation on the biology of NPC. NKILA might be a candidate molecular marker and a novel therapy target for NPC patients.

Abstract
IMPORTANCE The beneficial role of immunotherapy and the clinical relevance of current biomarkers in non-small cell lung cancer (NSCLC) remain inconclusive; thus, appropriate strategies and reliable predictors need further definition. OBJECTIVES To evaluate the association of clinical outcomes with immune checkpoint inhibitors, tumor vaccines, and cellular immunotherapy in patients with advanced NSCLC and to explore appropriate strategies, candidates, and predictors. DATA SOURCES The PubMed, EMBASE, and Cochrane Central Register of Controlled Trials databases were searched from inception to June 2018, using relevant search keywords and Medical Subject Headings (MeSH) terms, including tumor vaccine, cellular immunotherapy, immune checkpoint inhibitor, cytotoxic T-lymphocyte-associated protein 4, programmed death-ligand 1, programmed death receptor 1, and non-small cell lung carcinoma. Systematic reviews, meta-analyses, references, and conference proceedings were manually searched. STUDY SELECTION English-language randomized clinical trials with available data that measured overall survival (OS), progression-free survival (PFS), or objective response rate comparing immune checkpoint inhibitors, tumor vaccines, or cellular immunotherapy with conventional therapy for patients with advanced or metastatic NSCLC were included. Thirty-one immunotherapy randomized clinical trials were included, and multicohort data included next-generation sequencing data from patients with advanced NCSLC. DATA EXTRACTION AND SYNTHESIS Hazard ratios and 95% CIs were pooled to estimate the survival increases in OS and PFS. Dichotomous data, such as object response rate data, were analyzed using the risk ratio. Mantel-Haenszel random-effects model was used. I2 was used to assess the heterogeneity between trials; an I2 value exceeding 50% indicated the existence of substantial heterogeneity. Analyses took place from February 1, 2018, to August 31, 2018. MAIN OUTCOMES AND MEASURES Primary outcomes were OS and PFS. RESULTS In total, 14 395 patients (9500 [66.0%] men) were included in the meta-analysis, and 1833 patients (mean [SD], 65.2 [9.9] years; 1063 [58.0%] men) were included in the individual patient-level study. Compared with conventional therapy, immunotherapy was associated with significantly longer OS (hazard ratio, 0.76; 95% CI, 0.71-0.82; P < .001) and PFS (hazard ratio, 0.76; 95% CI, 0.70-0.83; P < .001). The best checkpoint blockade strategy was first-line pembrolizumab with platinum-based chemotherapy. The combined predictive utility of programmed cell death ligand 1 (PD-L1) expression and tumor mutation burden (TMB) was associated with predictive prognosis (whole-exome sequencing: 1-year PFS area under the receiver operating characteristic curve [AUC], 0.829; 3-year PFS AUC, 0.839; targeted next-generation sequencing: 1-year PFS AUC, 0.826; 3-year PFS AUC, 0.948). Moreover, the addition of CD8+ T-cell tumor-infiltrating lymphocytes was associated with improved prognosis predictions for OS (3-year OS AUC, 0.659; 5-year OS AUC, 0.665). RYR1 or MGAM mutations were significantly associated with concomitantly increased durable clinical benefits (RYR1: durable clinical benefit [DCB], 12 of 51 patients [24%]; no durable benefit [NDB], 2 of 55 patients [4%]; P < .001; MGAM: DCB, 12 of 51 patients [24%]; NDB, 0 patients; P < .001), a higher TMB (RYRI: high TMB, 12 of 53 patients [23%]; low TMB, 2 of 53 patients [38%]; P < .001; MGAM: high TMB, 9 of 53 patients [17%]; low TMB, 0 patients; P < .001), and higher PD-L1 expression (RYRI: high PD-L1 expression, 8 of 30 patients [27%]; low PD-L1 expression, 6 of 85 [7.1%]; P < .001; MGAM: high PD-L1 expression, 6 of 30 patients [20%]; low PD-L1 expression, 5 of 85 patients [6%]; P < .001). CONCLUSIONS AND RELEVANCE Immunotherapies showed promising clinical outcomes for patients with NSCLC. Pembrolizumab with platinum-based chemotherapy was found to be the most appropriate first-line immune checkpoint inhibitor regimen for advanced NSCLC, and the combined use of PD-L1 expression and TMB was found to be a promising biomarker to evaluate patients' survival and response to precision immunotherapy. The further combination of CD8+ T-cell tumor-infiltrating lymphocytes, PD-L1 expression, and TMB was associated with reliable prognosis. The predictive value of that combination needs to be prospectively validated in large-scale studies.

Abstract
The temporomandibular joint (TMJ) disc nutrient environment profoundly affects cell energy metabolism, proliferation, and biosynthesis. Due to technical challenges of in vivo measurements, the human TMJ disc extracellular nutrient environment under load, which depends on metabolic rates, solute diffusion, and disc morphometry, remains unknown. Therefore, the study objective was to predict the TMJ disc nutrient environment under loading conditions using combined experimental and computational modeling approaches. Specifically, glucose consumption and lactate production rates of porcine TMJ discs were measured under varying tissue culture conditions (n = 40 discs), and mechanical strain-dependent glucose and lactate diffusivities were measured using a custom diffusion chamber (n = 6 discs). TMJ anatomy and loading area were obtained from magnetic resonance imaging of healthy human volunteers (n = 11, male, 30 ± 9 y). Using experimentally determined nutrient metabolic rates, solute diffusivities, TMJ anatomy, and loading areas, subject-specific finite element (FE) models were developed to predict the 3-dimensional nutrient profiles in unloaded and loaded TMJ discs (unloaded, 0% strain, 20% strain). From the FE models, glucose, lactate, and oxygen concentration ranges for unloaded healthy human TMJ discs were 0.6 to 4.0 mM, 0.9 to 5.0 mM, and 0% to 6%, respectively, with steep gradients in the anterior and posterior bands. Sustained mechanical loading significantly reduced nutrient levels (P < 0.001), with a critical zone in which cells may die representing approximately 13.5% of the total disc volume. In conclusion, this study experimentally determined TMJ disc metabolic rates, solute diffusivities, and disc morphometry, and through subject-specific FE modeling, revealed critical interactions between mechanical loading and nutrient supply and metabolism for the in vivo human TMJ disc. The results suggest that TMJ disc homeostasis may be vulnerable to pathological loading (e.g., clenching, bruxism), which impedes nutrient supply. Given difficulties associated with direct in vivo measurements, this study provides a new approach to systematically investigate homeostatic and degenerative mechanisms associated with the TMJ disc.

Abstract
e14087 Background: Immune-related adverse events (irAEs) have been shown to be associated with the efficacy of immune checkpoint inhibitors in patients with advanced cancer, but the reported effect sizes have varied greatly in previous trials. We did a meta-analysis to assess immune checkpoint inhibitors efficacy and further explored the correlation of irAEs with efficacy in cancer. Methods: We systematically searched database inception to January, 2019 for randomized trials of immune checkpoint inhibitor in patients with advanced cancer that had available data for overall survival (OS) and progression-free survival (PFS), and irAEs. We calculated the pooled hazard ratios (HRs) and 95% confidence intervals [CIs] using a random-effects model, and assessed the association between the irAEs and PFS or OS using coefficient of determination ( R²). The PROSPERO registry number is CRD42017075610. Results: Thirty eight trials with 19,521 patients were included. Compared with conventional therapy, anti-PD-1 or PD-L1 combined with conventional therapy significantly enhanced survival (HR = 0.62, 95% CI 0.53 to 0.72 for PFS; HR = 0.71, 95% CI 0.58 to 0.87 for OS), and anti-PD1 or PD-L1 combined with anti-CTLA4 (HR = 0.75, 95% CI 0.63 to 0.90 for PFS). Anti-CTLA4 plus conventional therapy prolonged PFS (HR = 0.80, 95% CI 0.72 to 0.89) and OS (HR = 0.80, 95% CI 0.66 to 0.96) than conventional therapy alone. Anti-PD1 or PD-L1 outperformed anti-CTLA4 on OS (HR = 0.68, 95% CI 0.57 to 0.81). Significant correlation between treatment efficacy and irAEs was only identified in pneumonitis ( R2 0.59, P = 0.026 for PFS) and diarrhea ( R2 0.22, P = 0.006 for OS). Conclusions: We recommended the concurrent use of immune checkpoint inhibitor and conventional therapy or dual immunotherapy as the most appropriate regimens for advanced cancer. Furthermore, development of pneumonitis and diarrhea were associated with survival outcome of immune checkpoint inhibitors in patients with advanced cancer.

Abstract
e14122 Background: Our objective was to evaluate progression-free survival (PFS) and objective response rate (ORR) as surrogate end points for overall survival (OS) among patients with advanced non-small-cell lung cancer (NSCLC) in randomized trials of immunotherapy. Methods: Individual patient data (total N = 569 patients) were available from two multicentre, randomized, phase II/III trials (POPLAR and OAK). Analysis of OS, PFS and ORR were computed using the Kaplan-Meier estimates method and compared with the log-rank test, hazard ratios [HRs] and 95% confidence intervals [CIs] were calculated by using the Cox regression model. The surrogacy was evaluated using Spearman’s correlation coefficient (ρ) and coefficient of determination ( R²) between treatment effects on the surrogate end point and OS. We further validated the surrogacy in trial-level analysis with 26 NSCLC immunotherapy trials (total N = 12,094 patients) published prior to June 2018. Results: In the patient-level analyses, patients who achieved a response had better OS compared with nonresponders (HR 0.18; 95% CI, 0.11 to 0.29; P < 0.001). Greater OS was also observed in landmark anlyses at 6-month PFS (HR 0.21; 95% CI 0.11 to 0.39; P < 0.001) and 12-month PFS (HR 0.16; 95% CI 0.11 to 0.24; P < 0.001). PFS correlated with OS at the individual level (Spearman ρ = 0.37; P < 0.001). In the trial-level analysis, PFS moderately correlated with OS (Spearman ρ = 0.64; P < 0.001), and the R² was 0.50 (95% CI 0.39 to 0.64). Conclusions: In NSCLC immunotherapy trials, responders and patients with longer PFS had better OS. ORR and PFS are acceptable surrogates for OS in trials of immunotherapy, but caution must be taken when interpreting efficacy in the absence of OS data.

Abstract
1001 Background: Pyrotinib, an irreversible pan-ErbB receptor tyrosine kinase inhibitor, showed promising anti-tumour activity and acceptable tolerability in patients with HER2+ metastatic breast cancer (MBC) in phase 1/2 trials. Methods: This double-blinded, multicentre, randomised phase 3 trial was conducted in Chinese patients with HER2+ MBC previously treated with taxanes and trastuzumab. Patients were randomly assigned (2:1) to receive 400 mg pyrotinib or placebo orally once daily for 21-day cycles in combination with capecitabine (1000 mg/m2 orally twice daily on days 1–14). The primary endpoint (IRC-assessed progression free survival [PFS]) was assessed in patients who received ≥1 dose of study treatment. Patients whose disease progressed on placebo plus capecitabine received subsequent single agent pyrotinib. Results: Between July, 2016 and November, 2017, 279 patients were randomised to pyrotinib plus capecitabine (n = 185) or placebo plus capecitabine (n = 94) arms. The median PFS was 11.1 months (95% CI 9.66, 16.53) in the pyrotinib plus capecitabine arm and 4.1 months (95% CI 2.79, 4.17) in the placebo plus capecitabine arm. seventy-one patients in placebo plus capecitabine arm received subsequent pyrotinib, showing single-agent response rate of 38.0% (95%CI 26.7%, 49.3%) and median PFS of 5.5 months (95% CI 4.07, 6.90). The most frequent (≥5%) treatment-related ≥ grade 3 adverse events were diarrhoea (30.8% vs 12.8% ) and hand-foot syndrome (15.7% vs 5.3%). Conclusions: In women with HER2+ MBC previously treated with taxanes and trastuzumab, pyrotinib plus capecitabine yield statistically significant better PFS. Pyrotinib monotherapy showed anti-tumour activity. Clinical trial information: NCT02973737. [Table: see text]

Abstract
2573 Background: Atezolizumab, a programmed death ligand 1 (PD-L1) inhibitor, prolonged overall survival (OS) compared with docetaxel among patients with previously treated advanced non–small-cell lung cancer (NSCLC) in two independent multicentre, randomized trials (POPLAR and OAK). We conducted a combined analysis of the two trials to evaluate its efficacy and genomic biomarkers, and to further developed a novel predictive clinicopathologic-genomic nomogram of immunotherapy in NSCLC. Methods: Patients (N = 1,137) with stage IIIB/IV NSCLC and disease progression after previously platinum-based chemotherapy were randomly assigned (1:1) to receive atezolizumab (1200 mg/kg every 3 weeks) or docetaxel (75 mg/m2 every 3 weeks). The primary endpoint was OS. We applied a two-stage meta-analysis of pooled individual patient data in the intention-to-treat population. In OAK trial, patients treated with atezolizumab were randomly assigned (1:1) to the training group or the validation group to develop a predictive clinicopathologic-genomic nomogram of immunotherapy. POPLAR and OAK were registered with ClinicalTrials.gov, numbers NCT02008227 and NCT01903993. Results: In the pooled analysis, the median overall survival was 13.49 months (95% confidence interval [CI], 11.95 to 15.22) with atezolizumab versus 9.66 months (95% CI, 8.73 to 10.70) with docetaxel. The risk of death was 28% lower with atezolizumab than with docetaxel (hazard ratio [HR], 0.72; 95% CI, 0.62 to 0.83; P < 0.001). The race, sex, tumor histology, eastern cooperative oncology group performance status, PD-L1 expression, and especially pretreatment mutation (TP53, DNMT3A and KEAP1) were significantly associated with OS, and were used for the development of the predictive nomogram. The clinical use of the nomogram showed a closer association with 3-year OS than the blood-based tumor mutational burden (bTMB) or PD-L1 expression alone (nomogram, AUC = 0.818; bTMB, AUC = 0.701; PD-L1, AUC = 0.526) among NSCLC patients who had received atezolizumab. The superior predictability of the nomogram was further confirmed in the validation and entire OAK cohorts. Conclusions: Among patients with advanced, previously treated NSCLC, OS was significantly better with atezolizumab than with docetaxel. Furthermore, we constructed a novel and powerful clinicopathologic-genomic nomogram for personalized immunotherapy options.

Abstract
e12529 Background: Current guidelines lack definitive evidence regarding the clinical outcomes associated with different maintenance strategies for hormone-receptor (HR) positive metastatic breast cancer (MBC). We aimed to evaluate different maintenance modalities after first-line chemotherapy in this setting. Methods: We conducted a multicenter real world study to compare maintenance chemotherapy, endocrine therapy and observation in patients with HR positive MBC who achieved disease control after first-line chemotherapy. The primary endpoint was overall survival (OS), secondary endpoint was progression-free survival (PFS). We further examined the results from fourteen multicenter prospective studies in a meta-analysis. Results: A total of 928 patients were enrolled in the real world study. The median age was 48 years (range, 18 to 76 years). Of these patients, 269 received chemotherapy, 330 received endocrine therapy and 329 received observation as their maintenance treatment. OS was significantly longer in the chemotherapy group and endocrine therapy group than in the observation group (median 33.0 vs 36.0 vs 19.0 months, respectively, P < 0.001), as was PFS (median 12.0 vs 14.0 vs 8.0 months, respectively, P < 0.001). However, there was no significant difference of OS between chemotherapy group and endocrine therapy group (HR, 0.947, 95% CI: 0.743-1.207, P = 0.656), so did PFS (HR, 0.969, 95% CI: 0.787-1.194, P = 0.765). In the meta-analysis of all cohorts (2706 participants), maintenance endocrine therapy provide similar PFS and OS compare with chemotherapy, but with lower odds of G1-G2 adverse events. Conclusions: Our study provided strong evidence for OS and PFS benefits of maintenance therapy over observation after first-line chemotherapy in HR positive MBC patients. Maintenance endocrine therapy was noninferior to chemotherapy with less treatment-related toxicity, which was worthy of a clinical recommendation.

Abstract
1094 Background: Breast cancer treatment with immunotherapy can improve clinical benefits, but the majority of patients did not respond to the treatment. To understand tumor–immune interactions in breast cancer, we identified novel microenvironment-based immune molecular subtypes. Methods: A training cohort of 1,394 breast cancer patients from the Molecular Taxonomy of Breast Cancer International Consortium profiled by RNA and DNA sequencing data were analyzed to calculate immune-related gene biomarkers and to assign prognostic categories using LASSO Cox regression model. Additionally, 969 patients from The Cancer Genome Atlas data set was used as an independent validation cohort. We further compared tumor mutation burden (TMB) and cytolytic activity (CYT) levels between different immune molecular subtypes. Results: Using the LASSO model, we established an immune molecular classifier based on following 5 features: IFN-γ signature, ICOSLG, TNFRSF14, Mast.cells.resting, and T.cells. CD4.memory.resting. Then we found that it contained two distinct microenvironment-based subtypes (immune class and non-immune class), characterized by significant differences in overall survival in the training cohort (hazard ratio [HR] 0.71; 95% confidence interval [CI] 0.61 to 0.81; P < 0.001) and in the validation cohort (HR 0.34; 95% CI 0.22 to 0.54; P < 0.001). We found an inverse association between immune gene expression and TMB levels (ρ = 0.096, P < 0.001). Immune class subtype patients with good prognosis had significantly lower TMB and higher CYT than did non-immune class subtype patients with poor prognosis (all, P < 0.05). The clinical use of the immune molecular subtypes showed a closer association with survival than did IFN-γ signature or PD-L1 expression (all, P < 0.05). The robustness of the immune molecular subtypes was confirmed in the validation cohort. Conclusions: We revealed novel immune molecular subtypes, which represented better utility in predicting breast cancer patients’ survival compared with IFN-γ signature or PD-L1, and could be an important guide for precision immunotherapy.

Abstract
BACKGROUND The aim of the study was to probe the morphological features of the proximal segment (V1) of vertebral artery (VA) in a sample of Chinese cadavers. MATERIALS AND METHODS The origin, course and outer diameter at origin of the pre-vertebral part of the VAs were evaluated in 119 adult cadavers. RESULTS It was found that 94.12% of the VAs originated from the subclavian arteries, bilaterally. The variant origins were present in 5.88% of the cadavers and all originated directly from the arch of the aorta. All the variations were observed on the left side of male cadavers. The average outer diameters at origin of the normal and variation groups were 4.35 ± 1.00 mm and 4.82 ± ± 1.42 mm, respectively, p = 0.035. In the normal group, but not in the variation group, the average diameter in the males was significantly larger than that in the females (4.50 ± 0.99 mm, 3.92 ± 0.92 mm, respectively, p = 0.000). In addition, only 5 cadavers in the normal group had hypoplastic VAs (4.20%, 4 males, 3 right-sided). Vertebral artery dominance (VAD) was present in 91 (69 males) out of 112 cadavers and more common on the left (n = 48). In addition, 3 cadavers satisfied conditions for coexistence of VAD and vertebral artery hypoplasia. All 7 cadavers in the variation group exhibited VAD, which was more common on the right side (n = 5). CONCLUSIONS The morphologic variations and frequencies described above have implications for the early prevention, abnormal anatomy detection, accurate diagnosis, safe surgery and endovascular treatment of cardiovascular and neurological disease.
