e18084 Background: Previous studies indicated the carcinoembryonic antigen (CEA) could predict the therapeutic objective response (OR) and overall survival (OS) of patients with cancers, including non-small cell lung cancer (NSCLC). However, the role it could play in evaluating therapeutic responses and OS in patients with NSCLC requires further elucidation. Herein, we investigated the potential role of CEA in predicting OR and OS in patients with NSCLC. Methods: 689 patients with NSCLC were enrolled between January 2000 and August 2011. The correlations between the CEA levels and OR or OS were examined via statistical analyses including the chi-squared test, logistical regression, paired-samples t-test, receiver operator characteristic curve, Kaplan-Meier survival analysis, log-rank test and Cox regression model. Results: The calculated cut-off for predicting an OR to chemotherapy in patients with NSCLC was a reduction of 5.28% in serum CEA. This value demonstrated a sensitivity of 61.3% and a specificity of 62.4%. Serum CEA levels significantly decreased after two cycles of chemotherapy in NSCLC patients (t = 2.196, P = 0.031). The Kaplan-Meier survival analysis indicated no significant correlation between baseline CEA and OS (log rank test =0.079). However, according to the Cox regression analysis the number of distant metastatic organs (=1 and ≥2) was the independent risk factor of the OS (P = 0.026; P =0.003), and the cycle numbers of chemotherapy was the protective factor for OS in patients with NSCLC (P=0.011).More importantly, baseline serum CEA was significantly associated with lung adenocarcinoma and adenosquamous subtypes (P = 0.014; P = 0.017, respectively). Conclusions: Our study shows that baseline serum CEA was significantly associated with lung adenocarcinoma and adenosquamous subtypes. While the baseline level of serum CEA was not a prognostic factor, the post-treatment reduction of serum CEA level can predict the OR in patients with NSCLC,. The number of chemotherapy cycles was the independent protective factor, while the numbers of distant metastatic organs was the independent risk factor for NSCLC patients’ OS.

Abstract Background: Non small cell lung cancer (NSCLC) is one of the main causes of death in human diseases. In this study, we aimed to explore the prognostic value of serum circ_0048856 in patients with NSCLC and its relationship with miR-1287-5p.Methods: The expression levels of circ_0048856 and miR-1287-5p in serum of NSCLC patients and healthy people were detected by qRT-PCR. The relationships between circ_0048856 expression and clinical data were evaluated via χ2 test. Overall survival analysis was carried out via Kaplan-Meier method with log rank test. Cox regression analysis was taken to evaluate the prognostic ability of circ_0048856 in NSCLC. Luciferase reporter gene was used to detect the targeting relationship between circ_0048856 and miR-1287-5p.Results: The expression of circ_0048856 in serum of NSCLC patients was significantly higher than that of healthy volunteers (P < 0.001). And its high expression was significantly correlated with TNM stage (P = 0.002) and lymph node metastasis (P < 0.001). In addition, Kaplan Meier log rank test analysis showed that the overall survival of patients with high expression of circ_0048856 was significantly shorter than that of patients with low expression of circ_0048856 (log rank test, P = 0.002). Serum circ_0048856 expression is an independent prognostic biomarker in NSCLC patients. Furthermore, we found that miR-1287-5p is a direct downstream miRNA of circ_0048856 through luciferase reporter gene analysis, and there is a negative correlation between circ_0048856 and miR-1287-5p.Conclusion: Serum circ_0048856 is an independent prognostic biomarker in patients with NSCLC. Circ_0048856 can participate in the progression of NSCLC by targeting miR-1287-5p.

Objective In advanced maxillary sinus cancers treated with surgery and radiotherapy, poor local control rates and the potential for organ preservation have prompted interest in the use of systemic therapy. Our objective was to present outcomes for induction compared to adjuvant chemotherapy in the maxillary sinus. Study Design Secondary database analysis. Setting National Cancer Database (NCDB). Subjects and Methods In total, 218 cases of squamous cell maxillary sinus cancer treated with surgery, radiation, and chemotherapy between 2004 and 2012 were identified from the NCDB and stratified into induction chemotherapy and adjuvant chemotherapy cohorts. Univariate Kaplan-Meier analyses were compared by log-rank test, and multivariate Cox regression was performed to evaluate overall survival when adjusting for other prognostic factors. Propensity score matching was also used for further comparison. Results Twenty-three patients received induction chemotherapy (10.6%) and 195 adjuvant chemotherapy (89.4%). The log-rank test comparing induction to adjuvant chemotherapy was not significant ( P = .076). In multivariate Cox regression when adjusting for age, sex, race, comorbidity, grade, insurance, and T/N stage, there was a significant mortality hazard ratio of 2.305 for adjuvant relative to induction chemotherapy (confidence interval, 1.076-4.937; P = .032). Conclusion Induction chemotherapy was associated with improved overall survival in comparison to adjuvant chemotherapy in a relatively small cohort of patients (in whom treatment choice cannot be characterized), suggesting that this question warrants further investigation in a controlled clinical trial before any recommendations are made.

21040 Background: Gene expression arrays and IP studies classified breast cancer in three distinct subtypes: basal, HER2/neu and luminal that are associated with different clinical outcomes. Methods: In 141 pts with operable breast cancer, included in phase III trials of adjuvant therapy in our center, immunohistochemical staining was performed on 3μm sections of paraffin blocks, containing tissue-arrays of tumour tissue.A basal phenotype (BP) was defined by negative estrogen receptor (ER) and progesterone receptor (PR) and positive cytokeratin (CK) 5/6 or EGFR immunoreactivity. HER2/neu phenotype as positive c-erb B2 by HercepTest™ and luminal phenotype (LP) by positive ER, PR and CK 7/8 and negative HER-2. Survival curves were calculated by the Kaplan-Meier method. The differences between survivals were estimated using the log rank test. Multivariate Cox regression analysis was used to evaluate any independent prognostic effect of the variables on disease-free survival (DFS). Results: Complete clinical follow-up information was available for 141 pts. The median follow-up period was 52 months (range 1–103 months). During this period, 13.8% pts died from breast cancer and 27.7% pts relapsed. At the time of the primary diagnosis 10.4% of the pts had lymph node negative disease and 89.6% had positive lymph nodes. 50.8% pts received taxane chemotherapy, 7.7% Trastuzumab, 62.3% radiotherapy and 61% pts received hormonotherapy. Positivity for LP was 65.2%, BP 9.9% and Her-2 phenotype 8.5%. 16.3% didn't fit for any of the three subtypes. Median DFS for BP: 24 moths, for LP and Her-2 phenotypes median DFS was not reached. 5 years DFS were; BP: 19%, LP: 63% and Her-2: 56%. Kaplan-Meier survival analyses demonstrated that the presence of a detectable BP was highly significantly associated with a worse DFS compared with the presence of a LP, log rank test (p= 0.0001). Multivariate Cox regression analyses estimated that the prognostic effect of BP in relation to DFS was independent of lymph node, stage and tumor size, HR: 0.12 95% CI (0.05–0.2). Conclusions: We found that expression of BP was associated with poor prognostic in the context of randomized phase III trials. No significant financial relationships to disclose.

556 Background: It is occasionally recognized that, in molecular targeted therapy, target-specific AEs can surrogate its efficacy, such as skin toxicities and anti-EGFR antibodies. Because of multikinase inhibitor, regorafenib is involved in various kinds of adverse events; however, the clinical associations between AEs and efficacy remain unclear. The aim of this study is to reveal what AEs could surrogate efficacy of regorafenib. Methods: AEs were graded according to CTCAE ver. 4.0. We defined as “CRP increased”, if CRP increased more than 5 mg/dl during treatment compared with the baseline level. Time to treatment failure (TTF) and overall survival (OS) were estimated using Kaplan-Meier methods and compared by the log-rank test. Covariates which were significant in univariate analysis were included in multivariate analysis. Results: One-hundred and two patients were enrolled in this study. Almost all patients were PS 0-1 and received 160mg of regorafenib as an initial dose. The median TTF and the median OS were 2.0 and 8.0 months, respectively. Major AEs were Hand-foot skin reaction (HFSR) in 82.4% (≥Gr3:38.2%), Hypertension (HT) in 39.2% (16.7%), Rash in 23.5% (8.8%), Blood bilirubin increased (BBI) in 58.8% (2.9%), Thrombocytopenia in 48.0% (3.9%), Neutropenia in 20.5% (0%), and CRP increased in 46.1%. Regarding TTF, in univariate analysis, BBI, AST increased Gr0-1, neutropenia, absence of CRP increased, Diarrhea, HFSR, and Rash Gr0-2 were associated with longer TTF. In multivariate analysis, HFSR (HR 0.34 95%CI 0.19-0.63, p = 0.001) and Rash ≥Gr3 (HR 2.43 95%CI 1.13-5.21, p = 0.023) retained to be significant. With respect to OS, in univariate analysis, AST increased Gr0-1, ALT increased Gr0-1, neutropenia, absence of CRP increased, HFSR, and Rash Gr0-2 were associated with longer OS. In multivariate analysis, HFSR (HR 0.47 95%CI 0.24-0.91, p = 0.026), neutropenia (HR 0.54 95%CI 0.30-0.95, p = 0.032) and AST ≥Gr2 (HR 5.72 95%CI 2.11-15.63, p = 0.023) retained to be significant. Conclusions: HFSR and neutropenia might surrogate regorafenib efficacy in mCRC. Elucidation of the mechanisms of these AEs may help to understand which the pathway is the key role of regorafenib treatment in mCRC.

Abstract Purpose This study will investigate the relationship between marital status and prognosis in small cell lung cancer patients. Methods Patients of SCLC was selected from the SEER database (1973-2013) and the patient sinformation. Kaplan-Meier analysis, log-rank test and Cox regression model were used for studying patientprognosis. Result 27069 SCLC patients eligible for inclusion were screened from the SEER database. Kaplan-meier test showed that the median OS values were 8, 7, 6 months in married, single and SDW patients, respectively. Conclusion This study shows that marital status is an independent prognostic factor for overall survival in SCLC patients. Married patients with small cell lung cancer have better prognosis than those who were divorced/separated, widowed and single.

Abstract Background There are many FDA-approved corticosteroid preparations available for intra-articular injection, however triamcinolone hexacetonide is not one of them. It was the intraarticular drug of choice among pediatric rheumatologists up until approximately a decade ago, when production of this medication ceased. It can be obtained in the United States and Canada via importation from Europe, but it is not FDA-approved at this time. We wish to compare the duration of remission of intraarticular triamcinolone hexacetonide (TH) with that of triamcinolone acetonide (TA) in children with Juvenile Idiopathic Arthritis (JIA) and demonstrate its safety in this population. Methods This retrospective chart review included 39 patients with JIA who received intraarticular corticosteroid injections (IACIs) from September 2018 to September 2019. These patients were reviewed and their life-time injections with either TH (41 joints) or TA (124 joints) was noted through May 30, 2021. Patients with concomitant systemic therapy initiation were excluded. The primary outcome was time to relapse. Relapse was defined by the presence of arthritis on physical examination by an attending rheumatologist. Kaplan-Meier curves and a log-rank test were constructed to compare the probability of time to relapse between IACI injections. Additionally, mixed effects cox regression models were constructed to account for multiple injections per participant. Results Kaplan-Meier estimator of median relapse time in months was higher for TH. Based on the log-rank test, TA joints had a higher probability of experiencing a relapse during the study time (p-value < 0.001). The hazard of time to relapse was reduced when comparing TH to TA in both unadjusted and adjusted mixed effects cox regression models (unadjusted hazard ratio (95% confidence interval): 0.184 (0.089, 0.381); adjusted hazard ratio (95% confidence interval): 0.189 (0.092, 0.386)). Conclusions TH has longer duration of action than TA and is associated with less systemic side effects. It should be considered the drug of choice for intraarticular corticosteroid injections in children with JIA.

Background: Rising NT-proBNP are associated with reduced survival patients with HFrEF. However, it remains to be conclusively and formally demonstrated that the temporal trend in NT-proBNP level carries prognostic significance in HFpEF. Objective: To determine whether there is an association between rising NT-proBNP levels and 6-month survival in patients with HFpEF and HFrEF. Methods: We examined a cohort of 5203 patients to 5 hospitals in a regional health care system — who had at least one admission to the hospital with diagnoses of heart failure over a 3-year period. Kaplan-Meier survival curves were constructed for patients with downtrending (>25% net decrease), stable or uptrending (>25% net increase) NT-proBNP levels in HF, HFpEF and HFrEF patients. The log-rank test was used to test for differences in 6-month survival amongst the groups. Multivariate extended Cox regression models were constructed for 6-month survival with NT-proBNP as a time-varying covariate. Age, albumin, sex, race, serum creatinine, systolic and diastolic blood pressures and Charlson comorbidity scores at baseline were used as covariates in the model. Separate analyses were done for HFpEF and HFrEF patients. Results: HFpEF and HFrEF patients with up-trending levels had significantly lower 6-month survival rates than patients with downtrending or stable NT-proBNP levels. A doubling of the NT-proBNP level in patients was significantly associated with reduced 6-month survival in patients with in both subgroups of HF, HFpEF and HFrEF (HFpEF-HR: 1.53(1.49-2.57), HFrEF HR: 1.45(1.43-1.48) after adjusting for covariates.

Abstract Background: Previous studies have demonstrated that microRNAs (miRNAs) played a crucial role in various diseases, including cancers. The aim of the study was to evaluate the clinical significance of miR-124 in patients with cholangiocarcinoma (CCA).Methods: The expression pattern of miR-124 was detected in CCA tissues using quantitative reserve transcription polymerase chain reaction (qRT-PCR). The correlation of miR-124 expression with clinicopathological features and overall survival of patients were explored using chi-square test, Kaplan-Meier methods and Cox regression analyses.Results: The miR-124 expression level was strong down-regulated in CCA tissues compared with normal para-cancerous tissues (P<0.001). Moreover, aberrant miR-124 expression was significantly associated with differentiation (P=0.045) and lymph node metastasis (P=0.040). In addition, Kaplan-Meier method and log-rank test revealed that patients with low miR-124 expression has a poorer overall survival compared with those with high miR-124 expression (P=0.002). Furthermore, multivariate analysis confirmed that miR-124 expression (P=0.006; HR=2.006; 95%CI: 1.224-3.289) was an independent prognostic indicator in CCA.Conclusions: Collectively, our results defined miR-124 expression plays important roles in CCA patients. MiR-124 expression might used as a valuable prognostic biomarker for patients with CCA.

Abstract Background: Lung cancer is the leading cause of cancer-associated mortality worldwide, and in China. Central nervous system (CNS) metastasis is a prevalent and serious complication. The most common treatment for BM is still radiation therapy (RT). An increasing number of drugs have been shown to have intracranial activity or to sensitize tumours to radiotherapy.Methods: Our study aims to demonstrate the clinical efficacy of apatinib combined with radiotherapy vs. radiotherapy alone in the treatment of patients with advanced multiline failure for non-small-cell lung cancer with brain metastasis (BM). Eligible patients were divided into two groups: Apatinib + RT group and RT group. In the apatinib + RT group. Intracranial PFS and OS were analysed using the Kaplan-Meier method. Differences between groups were compared by the log-rank test.Results: The median intracranial PFS for the RT group and Apatinib+RT group was 5.83 months and 11.81 months (p=0.034). The median OS for the RT group and Apatinib+RT group was 9.02 months and 13.62 months (p=0.311). The Apatinib+RT group had a better intracranial PFS, but there were no significant differences between the two arms in OS. The Apatinib+RT group had significantly reduced symptoms caused by BM, mainly headache and vomiting. Most patients tolerated the side effects well. Conclusion: RT combined with apatinib could help to control intracranial metastases. The Apatinib+RT group had significantly reduced symptoms caused by BM, the safety of the two treatments was similar.

Abstract Background: In this study, we focused on the role of overhydration (OH) and low serum prealbumin concentration in predicting 3-year peritonitis in continuous ambulatory peritoneal dialysis (CAPD) patients.Methods: We measured serum prealbumin concentration and OH by body composition monitor on 278 CAPD patients (159 males and 119 females) with mean age of 46 years and the median peritoneal dialysis (PD) duration of 21 months. PD-related peritonitis was collected for 3 years. Results: After the 3-year follow-up, 44 patients diagnosed PD-related peritonitis (15.8%). Low education, serum albumin, prealbumin, high CRP-hs and OH were independent risk factors for predicting peritonitis during 36 months in CAPD patients. Based on the ROC curve model and Kaplan–Meier analysis, we realized that patients with low prealbumin and high OH were the independent predictors of 3-year peritonitis in CAPD patients (Prealbumin: AUC = 0.838, cut-off value = 32.5 mg/dL, Se= 90.9%, Sp = 32.9%; OH: AUC = 0.851, cut-off value = 1.33 L, Se = 79.5%, Sp = 85.5%; and Log-rank test p < 0.001, respectively). Conclusion: Overhydration and low serum prealbumin level were the independent predictors of PD-related peritonitis in CAPD patients.
