11097 Background:The Hu/ELAV mRNA binding protein HuR is normally localized to the nucleus and is activated upon stress. Previously, we observed that HuR expression is predominantly cytoplasmic in aggressive forms of pancreatic ductal adenocarcinomas (PDA). Additionally, we have shown that overexpression of HuR in pancreatic cancer cell lines renders them hypersensitive to gemcitabine (GEM). GEM is the standard first line therapy used against PDA. This study was designed to determine the relationship between endogenous HuR expression levels and patient outcome. Methods: We analyzed tissue from 29 resected PDA patients who did not receive neoadjuvant therapy. We determined the intensity of cytoplasmic HuR expression. All patients received adjuvant GEM, alone or in combination with radiation therapy or other chemotherapeutics. Correlation between HuR expression levels and overall survival was evaluated. Results: The median overall survival was 20.6 months, with 18 deaths observed. Median overall survival for low HuR expression was 15.3 months. Median overall survival for high HuR expression was not reached at a follow up of 40 months. A univariate Cox regression model gives a hazard ratio of low to high HuR of 3.36 (p=0.025) [95% CI 1.09–10.35]. Adjusting for age, sex, and radiation therapy in this patient group gives an adjusted hazard ratio of 5.04 (p = 0.03) [95% CI 1.15–22.02]. This indicates a 5-fold increase in risk of death in patients with low HuR levels compared to high HuR levels among patients receiving GEM. Conclusions: This is the first report of a correlation between levels of cytoplasmic HuR expression and overall survival in GEM treated patients. Together with our previously reported experimental data, HuR is regulating the key metabolic enzyme for GEM activation (deoxycytidine kinase). Therefore, HuR is a marker for therapeutic efficacy of GEM based regimens and is a candidate target for the optimization of GEM based treatment strategies.

210 Background: The plasma membrane xCT cystine-specific subunit of the cystine/glutamate transporter contributes to chemotherapy resistance in pancreatic cancer by regulating intracellular glutathione levels and protecting cancer cells against oxidative stress. We previously noted that the rs7674870 single nucleotide polymorphism (SNP) of xCT correlated with overall survival in pancreatic cancer and may be predictive of platinum resistance. There are no data regarding xCT protein expression in pancreatic cancer or the functional significance of this SNP. Methods: Paraffin-embedded core and surgical biopsy tumor specimens from 49 patients with metastatic pancreatic adenocarcinoma were analyzed by immunohistochemistry (IHC) using an xCT specific antibody (Novus Biologicals). xCT protein IHC expression scores (product of intensity and percentage of staining cells) were analyzed in relation to overall survival and genotype of the patients using the one factor ANOVA test, Kaplan-Meier plot, log-rank test, and Cox regression analysis. Overall survival was measured from the date of diagnosis to the date of death or last follow-up. Results: Positive xCT expression was detected in 38 (78%) of the 49 samples, and 9 (18%) patients had high levels of expression. High xCT expression was associated with lower overall survival as compared with low expression (5.1 months versus 8.8 months; p = 0.119). In a multivariate Cox regression model with adjustment for prognostic parameters of age, sex, performance status and CA19-9 level, high xCT expression was associated with a 2.1-fold increased risk of death (p = 0.096). Performance status also correlated with overall survival (p = 0.027). Preliminary analysis on the genotype-phenotype association (n = 12) indicated that xCT expression was higher with the TT genotype than the TC/CC genotype (p = 0.115), which is consistent with the previous observation that the TT genotype was associated with reduced survival. Conclusions: These data provide supporting evidence for a possible role of cystine/glutamate transporter xCT subunit in pancreatic cancer progression and survival. Further pharmacogenomic and clinicopathologic studies are ongoing. No significant financial relationships to disclose.

Abstract PURPOSE Brain metastases (BMs) represent the most common adult intracranial malignancy. The prognosis of BMs is subject to many factors, i.e., the number, size and locations of the metastatic sites, tumor origins, pathologic types, gene mutation status, metastatic sites, and KPS etc. This study aimed to evaluate the prognostic value of neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and lymphocyte-to-monocyte ratio (LMR) in brain metastases. METHODS A total of 480 patients diagnosed with brain metastases from a wide range of tumor origins, i.e., NSCLC, SCLC, breast cancer, melanoma, prostate, kidney, gastrointestinal cancer, cervical carcinoma, ovarian cancer, choriocarcinoma of uterus were retrospectively analyzed. Pre-radiotherapy NLR, PLR, and LMR were calculated as total neutrophil/lymphocyte, platelet/Lymphocyte, lymphocyte/monocyte, respectively. Survival rates were estimated using the Kaplan-Meier survival analysis. Cox regression models were used to identify independent prognostic factors. RESULTS The median overall survival (OS) was 14.4 months [95%CI: 13.4-15.5]. The median overall survival after radiotherapy was significantly different between patients with NLR< 4 and those with NLR≥4 (OS 16.3 mo. vs. 12.2 mo., P< 0.0001). No significant difference was observed between PLR vs. OS, and LMR vs. OS (PLR< 180: HR=1.221, P=0.240; LMR< 4: HR=0.753, P=0.141). The Cox regression model for the continuous metric values revealed that the NLR increased every 1.0 was associated with additional 5.9% of fatal risk (HR: 1.059; 95%CI = 1.033–1.087, P< 0.0001). NLR was validated as an independent prognostic factor for risk of death after adjusting for sex, age, and KPS. CONCLUSIONS We revealed pre-treatment NLR is an independent prognostic factor in patients with brain metastases for poor OS, independent of different tumor origins. The NLR warrants further studies using sub-group analysis and validation in external cohorts. Future studies in this parameter have a potential to facilitate more precise risk-stratifications to guide personalized treatment for BM.

251 Background: Combination chemotherapy with nab-paclitaxel/gemcitabine is a standard of care option in metastatic pancreatic cancer management with increasing use due to an improvement in median overall survival of 1.8 months compared to gemcitabine alone. It is also used in practice in the second and third-line settings for patients that have progressed on fluorouracil based regimens. As the utility of this combination chemotherapy has grown, dose intensity (DI) in relation to survival outcome is an important measure for real world application. Methods: Fifty-six patients that were 18 years or older with metastatic pancreatic cancer treated with nab-paclitaxel/gemcitabine as first-line therapy from January 1, 2013 to December 31, 2014 at Moffitt Cancer Center were identified through medical records. The subjects were retrospectively reviewed, and demographic, treatment outcomes (survival and progression), and DI were collected. Overall survival was calculated with Kaplan Meier survival curves. Multi-Cox regression models estimated multivariable-adjusted hazard ratio with 95% confidence intervals. Results: There was no significant relationship between receiving a DI > 85% regimen in relation to independent variables of age > 65, sex, primary site, and known distant metastasis; however DI > 85% was significant for patients that received additional chemotherapy following nab-paclitaxel/gemcitabine (p = 0.044). The DI > 85% group compared to the < 85% group had a hazard ratio (HR) for all-cause mortality of 0.285 (0.106-0.764, p = 0.013). Six and 12-month survival were higher in the DI > 85% group (p = 0.009, p = 0.02 respectively). Conclusions: DI > 85% for nab-paclitaxel/gemcitabine compared to DI < 85% may have a lower all-cause mortality and higher 6 and 12-month survival.

Abstract Background: Despite advances in early diagnosis and treatment, cancer remains the leading cause of mortality worldwide. The insulin-like growth factor 2 mRNA binding protein(IGF2BP) family has been reported to be involved in a variety of human malignant tumours. However, little is known about their expression and prognostic value in human pancreatic cancer. Therefore, we performed a detailed cancer versus normal differential analysis. Methods: The Cancer Genome Atlas (TCGA) and Gene Expression Profiling Interactive Analysis (GEPIA) databases were uesd to analyse the mRNA expression levels of the IGF2BP family in various cancers, including pancreatic cancer. Then, the LinkedOmics and GEPIA databases were used to assess the relation between the expression levels of IGF2BPs and overall survival (OS). Then, univariate and multivariate Cox regression analyses were performed , and subgroups based on grade and stage were analysed. The signalling pathways associated with IGF2BP2 and IGF2BP3 were then investigated via gene set enrichment nalysis(GSEA). Results: IGF2BP2 and IGF2BP3 were associated with each subset of OS based on grade and stage. Further clinical correlation analysis of IGF2BP2 and IGF2BP3 confirmed that IGF2BP2 and IGF2BP3 are fundamental factors in promoting pancreatic cancer progression. Conclusion: IGF2BP2 and IGF2BP3 are key factors in promoting the progression of pancreatic cancer and are closely related to overall survival.

Abstract BACKGROUND Pilocytic astrocytoma (PCA) is a low-grade glioma common in children but also rarely diagnosed in adults. The role of adjuvant radiation therapy (RT) in treating these tumors remains unclear. OBJECTIVE We investigated the effect of RT on overall survival, specifically among adult patients who had undergone subtotal PCA resection. METHODS Information on adult patients (age 18 years old) who had undergone subtotal PCA resection between 2004 and 2016 was collected from the National Cancer Database (NCDB). A multivariate Cox proportional hazards model was utilized to determine factors independently associated with overall survival. RESULTS A total of 451 patients were identified. The mean age of our patient cohort was 36.8 years old, and the majority of patients (83.4%) did not receive radiation treatment following subtotal PCA resection. Overall median survival was 93.8 months. Survival was longer (p &lt; 0.001) in the patients who did not receive post-surgical RT (median: 98.3 months) compared to patients who did (median: 54.8 months). Patients who had older age at diagnosis (hazard ratio [HR]=1.05, 95% confidence interval [CI]=1.03-1.07, p &lt; 0.01), were Black or African American (HR=2.76, CI=1.12-6.46, p=0.019), received radiation during their initial treatment (HR=4.53, CI=2.08-9.89, p &lt; 0.01), or had a Charlson/Deyo score of &gt; 1 (HR=3.68, CI=1.55, p=0.003) had a significantly higher risk of death following subtotal PCA resection. CONCLUSION Postoperative RT is independently associated with a significantly higher risk of death among adults who underwent subtotal PCA resection. Our findings provide a rationale for further investigation into the efficacy and safety of RT within this patient population.

Introduction The metastatic pancreatic adenocarcinoma clinical trial (MPACT) trial established gemcitabine (gem) and nab-paclitaxel (nab) as a standard treatment for pancreatic cancer utilizing granulocyte colony-stimulating factors to manage neutropenia. This was a challenge for jurisdictions that do not use granulocyte colony-stimulating factors in palliative settings. We developed dosage guidelines to dose modify gem and nab without granulocyte colony-stimulating factors. We undertook a retrospective review to determine the efficacy and safety of these dose adjustment guidelines in the real world. Methods A multi-centered, retrospective chart review was performed on pancreatic patients between December 1, 2014, and August 21, 2018. Provincial electronic medical health records were reviewed. Using Log-rank statistics we determined the patient's progression-free survival and overall survival. Results Of 248 patients, 209 met patient selection criteria. Patients were excluded if they were lost to follow-up, on gem alone prior to nab/gem combination therapy or did not receive nab or gem. Patients who received nab/gem as first-line therapy had a median progression-free survival of 6.3 months (95% CI, 5.1–7.4), and median overall survival of 11.1 months (95% CI, 9.5–12.8). Those who received gem/nab in the second line had a median progression-free survival of 4.6 months (95% CI, 2.8–6.5), and median overall survival of 19.3 months (95% CI, 12.6–26.0). Conclusions The patient’s progression-free survival and overall survival taking nab/gem using our dose modification algorithm were equivalent or superior to the MPACT trial's progression-free survival and overall survival. Gem/nab can be given by our dose modification scheme without granulocyte colony-stimulating factor.

ObjectiveGrowing evidence has highlighted that the immune and stromal cells that infiltrate in pancreatic cancer microenvironment significantly influence tumor progression. However, reliable microenvironment-related prognostic gene signatures are yet to be established. The present study aimed to elucidate tumor microenvironment-related prognostic genes in pancreatic cancer.MethodsWe applied the ESTIMATE algorithm to categorize patients with pancreatic cancer from TCGA dataset into high and low immune/stromal score groups and determined their differentially expressed genes. Then, univariate and LASSO Cox regression was performed to identify overall survival-related differentially expressed genes (DEGs). And multivariate Cox regression analysis was used to screen independent prognostic genes and construct a risk score model. Finally, the performance of the risk score model was evaluated by Kaplan-Meier curve, time-dependent receiver operating characteristic and Harrell’s concordance index.ResultsThe overall survival analysis demonstrated that high immune/stromal score groups were closely associated with poor prognosis. The multivariate Cox regression analysis indicated that the signatures of four genes, including TRPC7, CXCL10, CUX2, and COL2A1, were independent prognostic factors. Subsequently, the risk prediction model constructed by those genes was superior to AJCC staging as evaluated by time-dependent receiver operating characteristic and Harrell’s concordance index, and both KRAS and TP53 mutations were closely associated with high risk scores. In addition, CXCL10 was predominantly expressed by tumor associated macrophages and its receptor CXCR3 was highly expressed in T cells at the single-cell level.ConclusionsThis study comprehensively investigated the tumor microenvironment and verified immune/stromal-related biomarkers for pancreatic cancer.

Abstract BackgroundAccording to the NAPOLI-1 trial, nanoliposomal irinotecan (nal-IRI) plus 5-fluorouracil/leucovorin (5-FU/LV) showed improved overall survival compared to fluorouracil alone for patients with metastatic pancreatic cancer who previously treated gemcitabine-based therapy. In that trial, Asian patients had frequent dose modification due to hematological toxicity. There has been limited information on the clinical benefit and toxicity of this regimen in a real-world setting. Herein, we assessed real-world experience of nal-IRI plus 5-FU/LV in patients with advanced pancreatic cancer after gemcitabine failure.MethodsWe conducted a single institution retrospective analysis of response, survival and safety in patients who had been treated with nal-IRI with 5-FU/LV. Patients with metastatic pancreatic ductal adenocarcinoma previously treated with gemcitabine-based therapy received nal-IRI (80mg/m2) with 5-FU/LV every 2 weeks. ResultsFifty-one patients received nal-IRI plus 5-FU/LV between January 2015 and December 2020. The median age was 67 years, and males were 58.8%. A total of 40 (78.4%) and 11 (21.6%) patients had received one and two lines of prior chemotherapy before enrollment, respectively. Median progression-free survival was 2.8 months (95% confidence interval [CI] 1.8-3.7) and median overall survival was 7.0 months (95% CI 6.0-7.9). Chemotherapy doses were reduced or delayed in 33 (64.7%) patients during the first 6 weeks and median relative dose intensity was 0.87. Thirty-six (70.6%) patients experienced any grade 3 or 4 adverse events. Most common grade 3 or 4 adverse event was neutropenia (58.8%) and most non-hematologic adverse events were under grade 2. Since the start of first-line chemotherapy, median overall survival was 16.3 months (95% CI 14.1-18.4).ConclusionsNal-IRI plus 5-FU/LV seems to be effective, with manageable toxicities, after gemcitabine-based treatment in patients with metastatic pancreatic ductal adenocarcinoma.

Aim: To evaluate prostate-specific antigen response (PSAr) defined as a ≥50% decrease in PSA concentration from the pretreatment value, as a prognostic factor in patients with metastatic castration-resistant prostate cancer (mCRPC) treated with abiraterone acetate (AA). Methods: Retrospective evaluation of patients with mCRPC treated with AA. Results: 124 patients were identified. Median overall survival and progression-free survival for patients achieving PSAr versus patients without PSAr were 29.3 versus 9.7 months and 17.0 versus 5.2 months, respectively. Multivariate analysis confirmed that PSAr correlated with better overall survival (hazard ratio: 0.19; 95% CI: 0.10−0.38; p < 0.001) and progression-free survival (hazard ratio: 0.24; 95% CI: 0.14−0.41; p < 0.001). Conclusion: PSAr can be utilized as prognostic and predictive factors in mCRPC patients treated with AA.

Background: Pancreatic cancer is a difficult-to-treat cancer with a late presentation and poor prognosis. Some patients seek traditional Chinese medicine (TCM) consultation. We aimed to investigate the benefits of complementary Chinese herbal medicine (CHM) among patients with pancreatic cancer in Taiwan. Methods: We included all patients with pancreatic cancer who were registered in the Taiwanese Registry for Catastrophic Illness Patients Database between 1997 and 2010. We used 1:1 frequency matching by age, sex, the initial diagnostic year of pancreatic cancer, and index year to enroll 386 CHM users and 386 non-CHM users. A Cox regression model was used to compare the hazard ratios (HRs) of the risk of mortality. The Kaplan-Meier curve was used to compare the difference in survival time. Results: According to the Cox hazard ratio model mutually adjusted for CHM use, age, sex, urbanization level, comorbidity, and treatments, we found that CHM users had a lower hazard ratio of mortality risk (adjusted HR = 0.67, 95% CI = 0.56-0.79). Those who received CHM therapy for more than 90 days had significantly lower hazard ratios of mortality risk than non-CHM users (90- to 180-day group: adjusted HR = 0.56, 95% CI = 0.42-0.75; >180-day group: HR = 0.33, 95% CI = 0.24-0.45). The survival probability was higher for patients in the CHM group. Bai-hua-she-she-cao (Herba Oldenlandiae; Hedyotis diffusa Spreng) and Xiang-sha-liu-jun-zi-tang (Costus and Chinese Amomum Combination) were the most commonly used single herb and Chinese herbal formula, respectively. Conclusions: Complementary Chinese herbal therapy might be associated with reduced mortality among patients with pancreatic cancer. Further prospective clinical trial is warranted.
