Background Centralized care for patients with pancreatic cancer is associated with longer survival. We hypothesized that increased travel distance from home is associated with increased survival for pancreatic cancer patients. Methods The National Cancer Database user file for all pancreatic cancer patients was investigated from 2004 through 2015. Distance from the patients’ zip code to the treating facility was determined. Survival was investigated using the Kaplan-Meier method. Cox hazard ratios (CoxHRs) were determined based on stage of disease, distance traveled for care, and clinical factors. Results 340 780 patients were identified. In the average age of 68 ± 12 years, 51% were male and 83% were Caucasian. For all stages of cancer, longer survival was associated with traveling farther ( P < .001). The survival advantage was longer for Caucasians than African Americans (3.7 months vs. 2.6 months, P < .001) Travel was associated with a 13% decrease in risk of death ( P < .001). Even controlling for the pathologic stage, traveling farther was associated with decreased risk of death (CoxHR = .91, P < .001). Discussion Traveling for care is associated with improved survival for pancreatic cancer patients. While a selection bias may exist, the fact that all stages of patients investigated benefited suggests that this is a real phenomenon.

IntroductionProstate cancer is a common malignancy in men that is difficult to treat and carries a high risk of death. miR-219-5p is expressed in reduced amounts in many malignancies. However, the prognostic value of miR-219-5p for patients with prostate cancer remains unclear.MethodsWe retrospectively analysed data from 213 prostate cancer patients from 10 June 2012 to 9 May 2015. Overall survival was assessed by Kaplan-Meier analysis and Cox regression models. Besides, a prediction model was constructed, and calibration curves evaluated the model’s accuracy.ResultsOf the 213 patients, a total of 72 (33.8%) died and the median survival time was 60.0 months. We found by multifactorial analysis that miR-219-5p deficiency increased the risk of death by nearly fourfold (HR: 3.86, 95% CI): 2.01 to 7.44, p<0.001) and the risk of progression by twofold (HR: 2.79, 95% CI: 1.68 to 4.64, p<0.001). To quantify each covariate’s weight on prognosis, we screened variables by cox model to construct a predictive model. The Nomogram showed excellent accuracy in estimating death’s risk, with a corrected C-index of 0.778.ConclusionsmiR-219-5p can be used as a biomarker to predict death risk in prostate cancer patients. The mortality risk prediction model constructed based on miR-219-5p has good consistency and validity in assessing patient prognosis.

435 Background: Pancreatic cancer patients with liver metastases had much poorer prognosis than those with other metastatic patterns. This study aimed to develop and validate a radiomics model to discriminate pancreatic cancer patients with liver metastases from patients with other metastatic patterns. Methods: We evaluated 77 patients advanced pancreatic cancer (APC) with different metastatic patterns and performed texture analysis on the region of interest (ROI). 58 patients and 19 patients were allocated randomly into the training cohort and the validation cohort with almost the same proportion of patients with liver metastases. An independent samples t-test was used for initial feature selection in the training cohort. Random Forest Classifier (RFC) was used to construct models based on these features in both cohorts and a radiomics signature (RS) was derived from the model. Then a nomogram was constructed based on RS and CA19-9, and validated with calibration plot and decision curve. The prognostic value of RS was evaluated by Kaplan-Meier methods. Results: A nomogram based on the RS and CA19-9 was constructed and it demonstrated good discrimination in the training cohort (AUC = 0.93) and validation cohort (AUC = 0.81). Kaplan-meier methods showed that patients with RS>0.61 had much poorer OS than patients with RS < 0.61 in both cohorts. Conclusions:This study presents a radiomics nomogram incorporating both RS and CA19-9, which can be used to discriminate advanced pancreatic cancer patients with liver metastases from patients with other metastatic patterns.

185 Background: Obesity is one of the factors commonly associated with pancreatic cancer risk, but its prognostic role for survival is debatable. This study aimed to determine the role of BMI in treatment outcomes of pancreatic cancer patients (pts) undergoing surgical resection followed by adjuvant therapy. Methods: We retrospectively reviewed 165 consecutive pts with pancreatic cancer undergoing pancreaticoduodenectomy at Indiana University Hospital between 2004 and 2008. Fifty-three pts who received adjuvant treatment [gemcitabine alone (C-group): n=19; gemcitabine + radiotherapy (CRT-group): n=34] at our institution were included in the analysis. The Kaplan-Meier method was used to estimate the disease-free survival (DFS) and overall survival (OS); log-rank test was used to compare these outcomes between BMI groups (normal 18.5-24.99 kg/m2 vs. overweight/obese ≥ 25 kg/m2). Results: The sample comprised 53 pts (28 males; median age 62 yrs) with a median follow-up of 18.6 months (mos). Thirty pts (56.6%) had their BMIs recorded before the date of surgery, and 23 pts prior to starting adjuvant therapy. Two (3.8%) pts were underweight, 21 (39.6%) had a normal BMI and 30 (56.6%) were overweight/obese. There was no statistically significant difference in the median DFS of obese/overweight and normal BMI pts irrespective of adjuvant therapy (C or CRT) (14.47 vs. 11.80 mos; p= 0.111). Obese/overweight pts had a better median OS [25.2 vs. 14.6 mos; p=0.045 overall (25.7 vs. 16.9 mos; p= 0.143 for the CRT-group and 17.3 vs. 13.4 mos; p= 0.050 for the C-group)], 1-year survival [96.7% vs. 61.9%; p < 0.0001 overall (95% vs. 64.3%; p= 0.001 for the CRT-group, and 90% vs. 57.1%; p=0.016 with C)], and 2-year survival [52.6% vs. 25.4%; p < 0.0001 overall (60.0% vs. 30.0%; p=0.0001 for the CRT-group and 37.5% vs. 14.3%; p=0.0002 for the C-group)] than patients with normal BMI. Conclusions: In our experience, overweight/obese pts undergoing surgery followed by adjuvant therapy have better survival rates than patients with normal BMI.

4037 Background: Patients (pts) with pancreatic cancer are at high risk for VTE, and the occurrence of VTE can affect pts’ prognosis. The purpose of this study was to evaluate the incidence of VTE and the impact of timing of VTE (early vs. late) on survival. Methods: Medical record of 260 pts with pancreatic cancer, newly referred to UT MDACC during one year period from 1/1/2006 to 12/31/2006, were reviewed for the incidence of VTE during a 2-year follow-up period from the date of diagnosis. All VTE episodes were confirmed by radiologic studies. Survival analysis was conducted using Kaplan-Meier analysis and Cox proportional hazard models. Results: Of the 260 pts, 47 pts (18%) had 51 episodes of VTE during the 2-year follow-up. The median age of the pts with VTE was 61 years (range: 28-86) and 53% were males. Of the 47 pts with VTE, 27 (57%) had PE, 19 (40%) had DVT and 1 had concurrent PE/DVT. Three pts had recurrent VTE during the study period. Median follow-up time for OS was 192 days (range: 1-1652 days). Kaplan-Meier Survival analysis showed that those who developed VTE earlier (within 30 or 90 days) had shorter median overall survival (OS) compared with those who had VTE beyond these time points. The hazard ratios, 95% CI, and median OS at 1 year are summarized in the table below. Conclusions: The incidence of VTE is high in pts with pancreatic cancer. The timing of VTE had a significant impact on OS; pts who had an early development of VTE had a shorter overall survival. [Table: see text]

489 Background: The introduction of thyrosinkinase inhibitors (TKI) changed the treatment of metastatic kidney cancer fundamentally. To elaborate the potential impact of TKI therapies, we studied trends in OS for patients with primary metastatic kidney cancer between 1998 and 2014 in Austria. Methods: All patients with primary metastatic kidney cancer aged ≥18 years, diagnosed from 1998-2009 were derived from the ANCR (n=2134). Patients diagnosed from 2004-2006 (n=316) were excluded (transition period of systemic therapies). To evaluate differences in OS between patients treated in preTKI-era and TKI-era, two periods were defined: 1998-2003 (before the introduction of Sunitinib in Austria, P1; n=926) and 2006-2009 (P2; n=542). Follow-up was complete until December 31st, 2014. OS rates were estimated by using the Kaplan-Meier method. The Cox proportional hazard model was used to calculate hazard ratios (HR). Results: A total 1468 patients was included in the analysis. The median age of the study population was 70 yrs (sd ±12) and did not differ between the two eras. The incidence of T1 tumors increased from 6.6% in P1 to 10% in P2 while T4 tumors decreased from 15% to 6.5% (p<0.001). Surgery rate remained stable at 48% (p=0.14). Five-year OS for patients undergoing surgery slightly increased from 16% in P1 to 20% in P2, although not significant (p=0.11). For patients without surgery 5-year OS improved from 4.3% in P1 to 7.9% in P2 (p=0.02). Apart from surgery, survival gain was observed for younger patients (<75 yrs) of 4% (p=0.04) and for T3/T4 tumors of 7% (p=0.008). The risk of death (HR) for patients treated in the TKI-era was reduced compared to the preTKI-era (HR 0.83, 95% CI 0.74-0.93) adjusted for sex, age, T-stage, and surgery. Survival advantage for patients undergoing surgery remained significant (HR: 0.50, 95% CI 0.45-0.57) after adjustment for TKI-era, sex, age, and T-stage. Conclusions: Patients with primary metastatic kidney cancer treated in the TKI era show improved OS compared to the cytokine era. Most benefit was observed in non-surgical patients, younger patients, and for T3/T4 disease. Surgery remains as an important therapy for additional survival benefit.

Background/Aims: Previous studies on the effect of metformin therapy on survival of pancreatic cancer patients obtained inconsistent findings. To reevaluate the prognostic value of metformin adjuvant treatment, a meta-analysis was carried out. Methods: Relevant articles addressing the association between metformin use and pancreatic cancer survival were electronically searched to identify eligible studies. Pooled hazard ratios (HRs) and 95% confidence intervals (95% CIs) were calculated to assess the strength of the association. Results: Totally, seventeen studies involving 36791 participants were included. Overall, metformin use was found to be significantly associated with a favorable OS (HR=0.88, 95% CI=0.80-0.97). Subgroup analyses by ethnicity showed a significantly reduced risk of death for metformin users compared with non-users in Asians (HR=0.74, 95% CI=0.58-0.94) but nonsignificant in Caucasians. When stratified by clinical stage, a remarkable reduction of mortality risk in patients at stage I-II treated with metformin (HR=0.76, 95% CI=0.68-0.86) was found as well as the group at stage I-IV (HR=0.88, 95% CI=0.79-0.99), but not in patients at stage III-IV. In the stratification analyses based on treatment strategy, metformin therapy was found to be associated with a better clinical outcome in patients receiving surgery or comprehensive therapy (HR=0.73, 95% CI=0.62-0.87; HR=0.88, 95% CI=0.79-0.97) but not chemotherapy. However, the overall analysis failed to show a significant association between metformin use and DFS (HR=1.54, 95% CI=0.94 -2.50) with only 2 studies enrolled. Conclusion: The current study has evidenced a significant association of metformin adjuvant treatment with the survival benefit for pancreatic cancer patients, suggesting a potentially available option for the treatment. Further investigation is needed.

220 Background: Indeterminate pulmonary nodules (IPNs) are often found on staging CT scans for pancreatic cancer and pose a treatment conundrum since resection is contraindicated in metastatic setting. Here we aim to determine the clinical outcome of pancreatic cancer patients with IPNs undergoing curative resection. Methods: Retrospective analysis of 1,182 pancreatic cancer patients in the institutional Oncology Registry between 2007 and 2017 was conducted. Survival probabilities were estimated using the Kaplan-Meier method. Time was calculated from diagnosis to death for overall survival (OS), and from operation to recurrence for recurrence-free survival (RFS). Cox regression models were used to assess the effects of demographic, clinicopathologic, and treatment variables on OS and RFS. Results: IPNs were found in 50 patients undergoing surgery (43 pancreatoduodenectomy, 7 distal pancreatectomy). Negative margins were obtained in 82% of patients. Six and 44 patients had stage 0/I and stage II disease, respectively. Twelve and 35 patients received neoadjuvant and adjuvant therapy, respectively. Over a median follow-up of 20 months from the time of diagnosis, 37 patients (74%) developed local recurrence or distant metastasis in liver (38%), lung (32%), peritoneum (8%), or other sites (8%). Median RFS was 14 months and median OS was 23 months. Tumor size (HR 1.56, CI 1.23-1.98, p < 0.01) and elevated pre-operative CA19-9 (HR 2.51, 1.22 – 5.15, p = 0.01) were associated with lower RFS. Tumor size (HR 1.43, CI 1.10-1.86, p < 0.01) and diabetes (HR 2.05, CI 1.02-4.11, p = 0.04) were associated with lower OS. Patients with lung only recurrence tended to have superior OS relative to other single sites (HR 2.05, CI 0.66-6.33, p = 0.21) or multiple sites (HR 2.30, 0.75-7.50, p = 0.15). Patients with lung only recurrence had a median survival after recurrence of 17.9 months compared to 6.5 months for other single sites or 4.3 months for multiple sites. Conclusions: Only a portion of IPNs develop into true lung metastasis and that isolated lung metastatic recurrence may confer a better survival over metastasis of other sites. Ongoing efforts will identify serum biomarkers to predict recurrence in the hopes of guiding future clinical practice.

3 Background: While treatment-related lymphopenia (TRL) is common and associated with poorer survival in multiple solid malignancies, little data exists for anal cancer. We evaluated TRL and its association with survival in anal cancer patients treated with chemoradiation (CRT). Methods: A retrospective analysis of 140 patients with non-metastatic anal squamous cell carcinoma (SCC) treated with definitive CRT was performed. Total lymphocyte counts (TLC) at baseline and monthly intervals up to 12 months after initiating CRT were analyzed. Multivariable Cox regression analysis was performed to evaluate the association between overall survival (OS) and TRL, dichotomized by G4 TRL ( < 0.2k/μl) two months after initiating CRT. Kaplan-Meier and log-rank tests were used to compare OS between patients with versus without G4 TRL. Results: Median time of follow-up was 55 months. Prior to CRT, 95% of patients had a normal TLC ( > 1k/μl). Two months after initiating CRT, there was a median of 71% reduction in TLC from baseline and 84% of patients had TRL: 11% G1, 31% G2, 34% G3, and 8% G4. On multivariable Cox model, G4 TRL at two months was associated with a 3.7-fold increased risk of death (p = 0.013). On log-rank test, the 5-year OS rate was shorter in the cohort with versus without G4 TRL at two months (32% vs. 86%, p < 0.001). Conclusions: TRL is common and may be another prognostic marker of OS in anal cancer patients treated with CRT. The association between TRL and OS supports the hypothesis that host immunity plays an important role in survival among patients with anal cancer. These results support ongoing efforts of randomized trials underway to evaluate the potential role of immunotherapy in localized anal cancer.

Abstract Background.The AMIGO2 extracellular domain has a leucine - rich repetitive domain (LRR) and encodes a type 1 transmembrane protein , and is a member of the AMIGO gene family .Although the abnormal expression of AMIGO2 is associated with multiple tumors , the relationship with pancreatic cancer is not clear .Methods.The expression of AMIGO2 mRNA and proteins in pancreatic cancer was analyzed using NCBI GEO database and GEPIA2、Human Protein Atlas database.The RNA sequencing data of pancreatic cancer and clinical data of pancreatic cancer patients in TCGA public database were retrospectively analyzed. AMIGO2 gene expression data and their corresponding clinical information in the sample were analyzed retrospectively. The diagnostic value of AMIGO2 expression in pancreatic cancer patients was determined by receiver operating characteristic (ROC) curve analysis. The effects of AMIGO2 expression differences on survival time of pancreatic cancer patients were analyzed by Kaplan-Meier Plotter database and GEPIA2 database.The correlation between AMIGO2 gene and TP53 mutation in pancreatic cancer was analyzed by UALCAN database and TIMER database. The similar genes of AMIGO2 in pancreatic cancer were analyzed by GEPIA2 database, and the biological behavior, cellular composition, molecular function enrichment analysis and protein interaction of similar genes were analyzed by DAVID database and Metascape database. enrichment analysis of AMIGO2 similar gene pathways using KEGG database. The MSIGDB cancer coexpression module in Harmonizome database and TIMER database were used to study the gene coexpression of AMIGO2 in pancreatic cancer. AMIGO2 transcription factors were predicted using the JASPER database. The pathway of AMIGO2 transcription factors and co-expression genes was studied by KEGG database.Results. The expression of AMIGO2 (GSE16515, GSE15471) in pancreatic cancer tissues was significantly higher than that in normal tissues (P < 0.05). The GEPIA2 database also confirmed that the expression of AMIGO2 in pancreatic cancer tissues was significantly higher than that in normal tissues. The expression level of AMIGO2 gene was correlated with lymph node metastasis and histological grade of pancreatic cancer (P<0.05). The high expression of AMIGO2 protein in pancreatic cancer was confirmed in Human Protein Atlas database. The overall survival rate and progression-free survival rate of pancreatic cancer patients with high expression of AMIGO2 were significantly shorter than those of patients with low expression of AMIGO2 in Kaplan-Meier Plotter database and GEPIA2 database. In the gene ontology analysis, it is found that AMIGO2 is involved in cell adhesion, proliferation, migration, apoptosis and other biological processes. KEGG analysis pathway is concentrated in the focal adhesion pathway, mitotic cell cycle changes, and the regulation of cell protein localization. Abnormal expression of AMIGO2 was found in pancreatic cancer caused by TP53 mutation in UALCAN and TIMER databases.In JASPAR database, we predicted that there are 10 transcription sites between AMIGO2 and transcription factor MYB. In addition, there are positive genes related to AMIGO2 in TIMER database and transcription factor MYB regulates tumor cell proliferation and apoptosis in PI3K-Akt signal transduction pathway and WNT signal pathway in pancreatic cancer.

Background:  Pancreatic cancer is the fourth leading cause of death associated with malignancy in the United States, and is thought to be the second leading cause of death in 2030 in the United Kingdom. In Asia, pancreatic cancer is the most fatal cancer with the lowest survival of all malignancies, 25-30% survival five years after surgery. Indonesia has no data on the survival of pancreatic cancer and the factors that affect it. The aim of this study is knowing the 1-year survival of pancreatic cancer and its influencing factors in Cipto Mangunkusumo Hospital, Jakarta.Method: A retrospective cohort study was performed using data from the medical records of pancreatic cancer patients dr. Cipto Mangunkusumo Hospital between January 2012 - December 2016. Factors age, sex, metastasis, stage, comorbid and treatment were analyzed bivariate and multivariate using Cox Proportional Hazards Regression to obtain Hazard Ratio (HR) for each prognostic factor. The cumulative survival of 1 year after diagnosis is expressed by the Kaplan-Meier curve.Results: Of 83 subjects the proportion of males was 62.7%, age ≥ 50 years 68.7%, with age range 33-79 years, and 55 years on average. In bivariate analysis, there was a statistically significant relationship of survival with comorbid variables (HR = 2,116, 95% 953 1,335-3,513, p 0,002), metastasis (HR = 3,802, 95% CI: 1,995-7,249, p 0.001), palliative treatment (HR = 2,108 , 95% CI: 1,077-4,125, p = 0,029) and group without treatment (HR = 2,924, 95% CI: 1,496-5,716, p = 0,002). Multivariate analysis showed that metastasis provided the greatest risk of death with HR = 4.306 (95% CI: 2.125-8.724, p 0.001). Palliative group HR was 2.510 (95% CI: 1,245-5,061 p = 0.010) while the group without treatment gave HR 2,535 (95% CI: 1,277-5,032 p = 0,008). The 1-year survival rate is 14%, with a median survival of 6 months.Conclusion: The overall survival of one year of pancreatic cancer patients was 14%, with a median survival of 6 months. The presence of metastasis and not the curative therapy of Whipple surgery in patients with pancreatic cancer in dr. Cipto Mangunkusumo Hospital is the main factor that negatively affect the survival of 1 year
