415 Background: Sarcopenia (Sp) or severe loss of muscle mass is a prognostic factor in cancer patients. We assessed the association between Sp and outcomes in borderline resectable or locally advanced/unresectable pancreatic cancer patients undergoing chemoradiation (CRT). Methods: We reviewed all patients who underwent CRT at an NCI-designated cancer center between 2007-2012. Patients with available pre-treatment imaging were included in the analysis. Sp was defined as a lumbar skeletal muscle area/height of < 55.4 cm2/m2 for males and < 38.9 cm2/m2for females. Sp was correlated to treatment toxicity, cause specific survival (CSS), and overall survival (OS). Analysis was performed using chi-square test for categorical variables and Mann-Whitney U test for continuous variables. Kaplan-Meier method and Cox regression was used for survival analysis. Results: A total of 86 patients met the inclusion criteria with 32 (37%) patients being sarcopenic. The median age was 70 (range 46-91) with a median follow-up of 14 months (3-68). The majority of patients were male (57%), had T3 disease (47%), or were borderline resectable (63%). Twenty nine (33.7%) patients underwent surgery. Sarcopenic patients were less likely to undergo surgery (p = 0.024) versus non-sarcopenic patients. Otherwise there was no difference in clinical or treatment factors. The 12-month actuarial OS for patients with and without Sp was 47.9% and 70.7%, respectively (p = 0.047). The 12-month actuarial CSS for patients with and without Sp was 48% and 76%, respectively (p = 0.007). On multivariable analysis, after controlling for T-stage, N-stage, resectability, gender, pre-treatment CA 19-9, and surgery, Sp was no longer associated with CSS (HR 0.284 95% CI 0.774-2.398) or OS (HR 1.077 95% CI 0.626-1.853). Surgery remained associated with CSS (HR 0.205 95% CI = 0.102-0.412) and OS (HR 0.187 95% CI 0.096-0.363). T-stage also remained associated with both CSS (HR 0.616 95% CI 0.410-0.925) and OS (HR 0.649 95% CI 0.440-0.957). Conclusions: The presence of Sp decreases the likelihood of undergoing curative surgery for pancreatic cancer. This may be another useful tool to identify poor prognosis patients.

e15787 Background: Nimotuzumab, a unique and affinity differentiated anti-EGFR antibody had been used in combination with gemcitabine on the treatment of pancreatic cancer patients. The aim of the study was to evaluate overall survival. Methods: Patients with newly diagnosed, locally advanced or metastatic pancreatic cancer, KPS ≥ 70 %, 18-72 years old, with adequate renal and liver function were included. Pts received gemcitabine 1000 mg/m2and nimotuzumab or placebo fixed dose of 400 mg once a wk, for 3 wks, followed by a 1-wk rest (d1, 8, 15, q28) until disease progression or unacceptable toxicity. The primary endpoint was OS and secondary PFS, ORR, CBR, safety and QoL. For OS determination, a KM log-rank test was used and a modified IPCW with a cox regression as a secondary analysis. On this evaluation using a modified IPCW model, 41.7% of pts from treatment arm and 42.7% from control arm who received 2nd and 3rd line treatment were censored after progression, while pts that did not receive 2nd and 3rd line treatment were weighted to compensate for the bias created by censoring switchers to 2nd and 3rd line treatment. Results: 192 pancreatic cancer pts were recruited. Ninety-six pts (62 male and 34 female) with a median age of 67 years, range (31, 83) were randomized to treatment arm and 96 pts (57 male and 39 female) with a median age of 64 years, range (41, 82) were randomized to control arm. In the primary analysis, median OS [95% CI] in the treatment arm was 8.57 mo [5.93, 10.90] vs 6.03 mo [4.97, 7.60] in the control arm. The HR [95% CI], 0.83 [0.62, 1.12] and p = 0.23 and when a modified IPCW model as a secondary analysis was used to remove the effect of 2nd and 3rd line therapies, the median OS was statistically significant with a HR [95% CI], 0.81 [0.67, 0.98] and a p = 0.030. The median PFS [95% CI] was 4.43 mo [3.67, 6.00] in the treatment arm vs 3.47 mo [2.60, 4.03] in the control arm with a HR [95% CI] 0.68 [0.51, 0.92] and p = 0.012. Conclusions: A modified IPCW model had proven that addition of nimotuzumab to gemcitabine increases median overall survival of newly diagnosed chemotherapy-naïve locally advanced or metastatic pancreatic cancer patients. Clinical trial information: NCT00561990.

326 Background: It is well known that locally advanced pancreatic cancer patients have a poor prognosis. Recently, hematologic markers showing systemic inflammatory status such as neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) have aroused much attention due to its potential to predict patient survival. In this study, we investigated whether pre-treatment NLR and PLR independently and in combination would be significant prognostic factors for survival in locally advanced pancreatic cancer patients. Methods: A total of 497 locally advanced (borderline resectable and unresectable) pancreatic cancer patients who received neoadjuvant or definitive chemoradiotherapy (CCRT) between January 2005 and December 2015 were included in this study. NLR and PLR prior to the start of treatment within 2 weeks were defined as pre-treatment NLR and PLR. We divided the patients with the median values of pre-treatment NLR and PLR; NLR < 2.44 group (n = 248), NLR ≥ 2.44 group (n = 249), PLR < 149 group (n = 248) and PLR ≥ 149 (n = 249) group. Overall survival (OS) and progression-free survival (PFS) were compared between each group for NLR and PLR. Results: Median overall survival was 15.7 months (range, 2.3-128.5 months). For NLR, the OS, PFS rates were significantly lower in the NLR ≥ 2.44 group, with 1-year OS rates of 67.9% and 61.5% (p = 0.003) and 1-year PFS rates of 38.1% and 32.4% (p = 0.003), for NLR < 2.44 and ≥ 2.44 group, respectively. The PLR ≥ 149 group also showed significantly poorer OS and PFS than PLR < 149 group. The 1-year OS rates were 68.1% and 61.3% (p = 0.029) and 1-year PFS rates were 37.9% and 32.5% (p = 0.027), for PLR < 149 and ≥ 149 group, respectively. When multivariate analysis was performed, NLR ≥ 2.44 remained as a significant adverse factor for OS (p = 0.011) and PFS (p = 0.026). PLR > 149 also proved to be a significant factor for poorer OS (p = 0.003) and PFS (p = 0.021). Conclusions: Elevated pre-treatment NLR and PLR independently and in combination significantly predicted poor OS and PFS. Pre-treatment NLR and PLR are useful prognostic factors for OS and PFS in locally advanced pancreatic cancer patients.

Abstract Background: Serum tumor markers including AFU, AFP, CEA, CA199, CA125 and CA724, are of great importance in the diagnosis, prognostic prediction and recurrence monitoring of gastrointestinal malignancies. However, their significance in gastric cancer (GC) patients with neoadjuvant therapy (NCT) is still uncertain. The aim of this study was to evaluate the predictive value of these six tumor markers in locally advanced GC patients who underwent NCT and curative surgery. Methods: In total, 290 locally advanced GC patients who underwent NCT and D2 radical gastrectomy were retrospectively analyzed. Data on their tumor markers before (pre-) and after (post-) NCT and pathological characteristics were extracted from the database of our hospital. The optimal cutoff values of the six tumor markers were calculated by the ROC curve and Youden index. Their predictive significance was analyzed and survival curves for overall survival (OS) were obtained by the Kaplan-Meier method. Associations between categorical variables were explored by the chi-square test or Fisher's exact test. Multivariate analyses were performed by the Cox regression model. Results: Pre- and post-CA199, -CA125 and -CA724 could predict overall survival (all P < 0.05), but only the change (diff-) of CA199 was related to prognosis (P = 0.05). In the multivariable analysis, pre- (P = 0.014) and post-CA724 (P = 0.036) remained significant, though diff-CA724 was not an independent prognostic factor (P = 0.581). In addition, pre- and post-CA199, -CA125 and -CA724 were associated with lymph node metastasis (N- vs N+) and pathological stage (Ⅰ-Ⅱ vs Ⅲ) (all P < 0.05). Moreover, post-CA724 was related to the vascular or lymphatic invasion (P = 0.019), while pre-CA724 was not (P = 0.082). However, AFU, AFP and CEA showed no association with survival (P > 0.05). Conclusions: CA724 is an independent factor for prognosis and could be used to predict ypN and ypTNM stage in locally advanced GC patients undergoing NCT and curative resection.

452 Background: Higher pre-treatment neutrophil-to-lymphocyte ratio (NLR) and lower platelet-to-lymphocyte ratio (PLR) are independent predictors for worse survival in cancer patients. The effect of chemoradiation (CRT) on NLR and PLR in pancreatic cancer patients who also undergo surgical resection has not been reported. Methods: A retrospective review was performed of pancreatic cancer patients treated at our institution with CRT either prior to or after surgery with curative intent. Overall survival was evaluated using Kaplan-Meier method. Univariate and multivariate Cox regression models were applied to evaluate the independent prognostic significance of NLR and PLR. Results: After excluding patients who did not have surgery, who received palliative radiation doses, or who had incomplete medical records, 81 out of 282 patients remained with median age 62 years (35-86). Of these, 24 (29.6%) were borderline resectable (BR) and received preoperative CRT while 57 (70.4%) received adjuvant CRT. Median total dose and number of fractions were 50.4 Gy (30-59.4) and 28 (5-33), respectively. Median pre-CRT and post-CRT NLR were 2.9 and 7.8, respectively. Median pre-CRT and post-CRT PLR were 211.3 and 457.5, respectively. Most patients had a decrease in NLR (85.2%) and PLR (72.8%) after CRT, with median changes of -4.95 for NLR and -178.33 for PLR. Cox proportional hazards analysis showed a trend towards significance for pre-CRT NLR (p=.08) regarding OS. A significant relationship was found between relapse free survival and both pre-CRT NLR (p=0.02) and PLR (p=0.01). The difference or percent change of neither NLR nor PLR was found to correlate with clinical outcomes. Conclusions: This is the first study to evaluate the effect of CRT on NLR and PLR in resected pancreas cancer patients. Similar to other reports, our data indicate that a significant relationship exists between NLR, PLR, and clinical outcomes. Identification of clinically meaningful NLR and PLR cut-off points for resected pancreatic cancer patients who also receive CRT is needed.

718 Background: Neo-adjuvant therapy is becoming a preferred approach in the management of BR pancreatic cancer patients. There is no consensus on an ideal treatment regimen. We report our experience with a combination of nab-Paclitaxel/Gemcitabine followed by concurrent Capecitabine and radiation treatments in BR pancreatic cancer patients. Methods: A prospectively maintained database of patients with BR pancreatic cancer undergoing neo-adjuvant treatments at our cancer center between 01/2013- 11/2017 was reviewed. Patients were treated with Gemcitabine(1gm/m2) and nab-paclitaxel (125mg/m2) given on D1-8-15 every 28 days. Pts. were re-assessed after two cycles and the responding pts received two additional cycles. Pts. who continued to respond after four cycles were treated with capecitabine (825mg/m2) and radiation treatments(50.4Gy). Results: A total of 32 patients with PS 0/1 were treated. Median age was 59 yrs (42-76), 19 Males and 13 females. After 2 cycles of Gem/nab-paclitaxel, none of the pts. had progressive disease. Thirty patients (93%) were able to complete all four cycles of Gem/nab-paclitaxel. Twenty nine (90%) received capecitabine and radiation treatments. Imaging to assess response was done 4 weeks after completing radiation and the results were were; 2 CR, 11 PR, 14 SD, 2 PD. Surgery was performed 6-8 weeks after completing radiation. Twenty six (81%) underwent planned resection, 2 had PD, 3 declined surgery and 1 had significant decline in PS. Twenty two out of Twenty six patients undergoing surgery had a R0 resection (80%). Grade-III/IV toxicities with the neo-adjuvant treatments were seen in 41% and 7 % of the pts., respectively. No thirty day post-op mortality, pancreatic leaks or re-operations were observed. The median PFS among all patients was 11.7 months, 2 yr OS 49% and median OS was 27.6 months, compared to 23.4 months, 65% and median OS not reached, in patients who underwent surgical resection. Conclusions: Nab-Paclitaxel and Gemcitabine followed by Capecitabine and radiation is an effective neo-adjuvant treatment strategy with acceptable toxicity-profile for patients with BR pancreatic cancer.

Methods: 290 locally advanced GC patients with NCT and D2 radical gastrectomy were retrospectively analyzed. Their tumor markers before (pre-) and after (post-) NCT and pathological characters were exacted from the database in our hospital. The optimal cutoff values of six tumor markers were calculated by ROC and Youden index. Their predictive significances were analyzed and survival curves on overall survival (OS) were obtained by Kaplan-Meier method. Associations between categorical variables were explored by Chi-square test or Fisher's exact method. Multivariate analyses were performed by Cox regression model. Results: Not only the pre- and post- CA199, CA125 and CA724 could predict the OS respectively, but also the changes (diff-) between post- and pre- groups were related to the prognosis (P < 0.05). In multivariable analysis, only pre- (P = 0.016) and post-CA724 (P = 0.033) remained significant, and the significance of diff-CA724 was on borderline (P = 0.085). Besides, pre- and post-CA199, CA125 and CA724 were associated with the metastasis of lymph node (N- vs N+) and pathological stage (Ⅰ-Ⅱ vs Ⅲ) (P < 0.05). Post-CA724 was related to the invasion of vascular or lymphatic vessels (P = 0.019), and pre-CA724 was nearly remarkable (P = 0.082). However, AFU, AFP and CEA showed no association with survival (P > 0.05). Conclusions: CA724 is an independent factor to prognosis, and could be used to predict the ypN and ypTNM stage in locally advanced GC patients undergone NCT and curative resection.

4123 Background: In the metastatic or adjuvant setting for pancreatic cancer, the combination chemotherapy of fluorouracil, leucovorin, irinotecan, and oxaliplatin (FOLFIRINOX) resulted in longer overall survival (OS) compared to gemcitabine therapy. We conducted an institutional study to compare the efficacy of neoadjuvant modified FOLFIRINOX (neo-mFOLFIRINOX) to adjuvant gemcitabine (adj-gem) for pancreatic cancer patients who completed resection. Methods: The study retrospectively enrolled patients from 2006 to 2017 from Ohio State University. While patients who received adjuvant gemcitabine were considered to be resectable upfront, patients who received neo-mFOLFIRINOX were either staged as borderline resectable (BR) or un-resectable (UR) by the institutional tumor board group. 111 patients received adj-gem (average cycles, 5.5) and 52 patients received neo-mFOLFIRINOX (average cycles, 3.5). The survival rates were determined by the Kaplan-Meier method and analyzed using Cox regression and log-rank test. Results: At a median follow up of 21.3 months, the median OS was 35.4 months in the neo-mFOLFIRINOX group and 21.8 months in the adj-gem group (hazard ratio, 0.56, 95% confidence interval (CI), 0.37-0.84 p = 0.005). The OS rate at 3 years was 46% in the neo-mFOLFIRINOX group and 22% in the adjuvant gemcitabine group (p = 0.001). The median disease free survival (DFS) was 18.6 months in the neo-mFOLFIRINOX group and 12.0 months in the adj-gem group (hazard ratio, 0.63, 95% CI, 0.43-0.93 p = 0.022). The DFS rate at 3 years was 17% in the neo-mFOLFIRINOX group and 11% in the adj-gem group (p = 0.02). On surgical pathological specimen review, the neo-mFOLFIRINOX group had statistically (p < 0.05) lower tumor grade, lower rates of perineural invasion and lymphovascular invasion, lower pathological T stage, lower pathological N stage, and lower number of nodes positive compared to the adj-gem group. Frequencies of obtaining R0 resections were higher in the neo-mFOLFIRINOX versus adj-gem groups but not statistically different (51.9% vs 40.4, p = 0.2). The average age and performance status were similar between the two groups. Conclusions: At our institution, BR and UR pancreatic cancer patients who received neo-mFOLFIRINOX and completed resection had longer OS, DFS, and more favorable pathological indicators compared to those patients who had upfront surgery and adjuvant gemcitabine. Randomized clinical trials comparing neoadjuvant versus adjuvant FOLFIRINOX are needed to validate these findings.
