Survival Outcomes for Induction vs Adjuvant Chemotherapy in Squamous Cell Carcinoma of the Maxillary Sinus

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.

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 one of the most common cancers, with high morbidity and mortality. MiRNAs are proved to play important roles in various human cancers. In our study, we aimed to explore the prognostic value of miR-181 in lung cancerMethods: Quantitative real-time polymerase chain reaction (QRT-PCR) was used to detect the expression level of miR-181 in lung cancer tissues and the paired non-cancerous tissues. The relationship between miR-181 expression and clinicopathologic parameters were analyzed by chi-square test. Kaplan-Meier method with log rank test was applied for overall survival analysis. Furthermore, the Cox regression analyses were performed to evaluate the prognostic value of miR-181 in lung cancer.Results: Down-regulated miR-181 expression was observed in lung cancer tissues (P<0.001), moreover, its expression was significantly correlated with TNM stage (P=0.015) and metastasis (P=0.000). In addition, lung cancer patients with lower miR-181 expression level had poorer overall survival than those with higher expression (log rank test, P=0.011). Cox regression analysis suggested that miR-181 was an independent prognostic factor for lung cancer (HR=1.961, 95%CI=1.135-3.388, P=0.016).Conclusion: MiR-181 may be a tumor suppressor gene in lung cancer, which can predict outcomes for the patients.

Purpose. To investigate whether lymphocyte nadir induced by radiation is associated with survival and explore its underlying risk factors in patients with hepatocellular carcinoma (HCC). Methods. Total lymphocyte counts were collected from 184 HCC patients treated by radiotherapy (RT) with complete follow-up. Associations between gross tumor volumes (GTVs) and radiation-associated parameters with lymphocyte nadir were evaluated by Pearson/Spearman correlation analysis and multiple linear regression. Kaplan–Meier analysis, log-rank test, as well as univariate and multivariate Cox regression were performed to assess the relationship between lymphocyte nadir and overall survival (OS). Results. GTVs and fractions were negatively related with lymphocyte nadir (p<0.001 and p=0.001, respectively). Lymphocyte nadir and Barcelona Clinic Liver Cancer (BCLC) stage were independent prognostic factors predicting OS of HCC patients (all p<0.001). Patients in the GTV ≤55.0 cc and fractions ≤16 groups were stratified by lymphocyte nadir, and the group with the higher lymphocyte counts (LCs) showed longer survival than the group with lower LCs (p<0.001 and p=0.006, respectively). Patient distribution significantly differed among the RT fraction groups according to BCLC stage (p<0.001). However, stratification of patients in the same BCLC stage by RT fractionation showed that the stereotactic body RT (SBRT) group achieved the best survival. Furthermore, there were significant differences in lymphocyte nadir among patients in the SBRT group. Conclusions. A lower lymphocyte nadir during RT was associated with worse survival among HCC patients. Smaller GTVs and fractions reduced the risk of lymphopenia.

Anaplastic pancreatic cancer (APC) is a rare undifferentiated variant of pancreatic ductal adenocarcinoma with poor overall survival (OS). The aim of this study was to evaluate the clinical outcomes of APC compared with differentiated pancreatic ductal adenocarcinoma. We conducted a retrospective review of all patients treated at the Mayo Clinic with pathologically confirmed APC from 1987 to 2011. After matching with control subjects with pancreatic ductal adenocarcinoma, OS was evaluated using Kaplan-Meier estimates and log-rank test. Sixteen patients were identified with APC (56.3% male, median age 57 years). Ten patients underwent exploration of whom eight underwent pancreatectomy. Perioperative morbidity was 60 per cent with no mortality. The median OS was 12.8 months. However, patients with APC who underwent resection had longer OS compared with those who were not resected, 34.1 versus 3.3 months ( P = 0.001). After matching age, sex, tumor stage, and year of operation, the median OS was similar between patients with APC and those with ductal adenocarcinoma treated with pancreatic resection, 44.1 versus 39.9 months, ( P = 0.763). Overall survival for APC is poor; however, when resected, survival is similar to differentiated pancreatic ductal adenocarcinoma.

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.

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.

e15756 Background: Preclinical studies have shown that calcium channel blockers (CCB) may potentiate anticancer effect of chemotherapy via intra-cellular drug accumulation. Gemcitabine-based chemotherapy is commonly used in pancreatic cancer (PC) patients. The aim of this study was to determine whether CCB may affect overall survival (OS) in PC patients receiving gemcitabine-based chemotherapy. Methods: The retrospective cohort of PC patients treated with gemcitabine between 2007 and 2016 was identified in the Polish National Health Fund databases. Electronic records of prescriptions were searched to identify in this cohort patients receiving CCB (amlodipine, nitrendipine, felodipine, lacidipine). The primary endpoint was OS and it was determined by Kaplan-Meier methods and compared by the log-rank test. Results: In total 4628 PC patients treated with gemcitabine (median OS 7.7 months; 95% CI: 7.4-7.9) were identified. Among these 380 patients were prescribed any CCB. There was a significant difference (p < 0.001) in median OS between patients prescribed CCB (n = 380; OS 9.3 months; 95% CI: 7.8-11.0) and those who did not (n = 4214; OS 7.6 months; 95% CI: 7.3-7.8) with hazard ratio for death 0.70 (95% CI: 0.62-0.79). Notably, the survival curves tended to flatten in CCB group, with 24% of patients alive at 2 years (95% CI: 20-29%) and 15% alive at 5 years (95% CI: 11-19%), compared with 11% (95% CI: 10-12%) and 4% (95% CI: 4-5%) in controls respectively. Conclusions: The use of CCB in PC patients receiving gemcitabine-based chemotherapy was associated with improved OS. Further validation is needed to evaluate effectiveness of CCB-gemcitabine combinations in the management of PC.

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 Eyes absent 4 (EYA4) is involved in various biological processes. The aim of this study was to investigate the expression of EYA4 and its prognostic value in colorectal cancer (CRC). Methods The mRNA level of EYA4 in diseased tissues and adjacent normal tissues of CRC patients were detected by quantitative real-time polymerase chain reaction (qRT-PCR). The association between EYA4 expression and clinicopathological characteristics was analyzed by χ2 test. Kaplan-Meier analysis with log rank test was performed to evaluate the effects of EYA4 expression on overall survival of CRC patients. Cox regression model was applied for prognosis analysis in CRC. Results The mRNA level of EYA4 was significantly decreased in CRC tissues compared with that in the adjacent normal tissue (P < 0.01). And its expression was affected by DUKE stage (P = 0.034), differentiation (P = 0.027) and vascular invasion (P = 0.037). Survival curve showed that patients with low expression of EYA4 had a significantly shorter overall survival than those with high expression (log rank test, P = 0.008). Low expression of EYA4 (HR = 1.989, 95%CI = 1.090-3.62902, P = 0.025) was an independent biomarker for poor prognosis in CRC patients. Conclusion EYA4 expression is decreased in CRC patients and negatively correlated with aggressive tumor progression. EYA4 may be a potential prognostic biomarker for CRC.
