Objectives: Multiple blood parameters are used to determine the prognosis of renal cell carcinoma (RCC). Mean platelet volume/platelet count (MPV/PC) ratio is related to disease progression in various cancers. Our study tried to evaluate the prognostic value of the MPV/PC ratio in RCC patients who underwent surgery. Methods: We retrospectively reviewed 89 patients who underwent radical or partial nephrectomy for RCC in a single institution. Baseline characteristics and MPV/PC ratios were analyzed. The optimal cut-off value of the MPV/PC ratio was determined by a receiver operating characteristic (ROC) curve, and our patients were divided into low and high MPV/PC ratio groups. The Kaplan–Meier survival curve and Cox proportional hazards model were applied for progression-free survival (PFS) and overall survival (OS) analyses. Harell’s C-index was used to compare the prognostic values of the MPV/PC ratio, MPV and PC. Results: Lower MPV/PC ratios were correlated with more advanced tumor stages and worse outcomes. The optimal cut-off value of the preoperative MPV/PC ratio was 0.034 (sensitivity 84.6%, specificity 56.6%). The Kaplan–Meier survival curve revealed that low MPV/PC ratios were associated with worse PFS (p = 0.007) and OS (p = 0.017). Multivariate analysis showed that low MPV/PC ratios were an independent unfavorable factor for PFS (p = 0.044) and OS (p = 0.015). Harell’s C-indexes showed that the prognostic value of the MPV/PC ratio was significantly better than MPV and PC (p < 0.001). Conclusion: Low MPV/PC ratios are an independent, unfavorable risk factor for disease progression and overall survival in patients undergoing surgery for RCC.

687 Background: Preoperative C- Reactive Protein (CRP) has predictive value for metastasis development and mortality in renal cell carcinoma (RCC). However, the predictive potential of preoperative CRP at presentation on survival after nephrectomy remains unclear. This study investigates the prognostic value of preoperative CRP on overall long term survival in RCC patients post-nephrectomy. Methods: 683 post-nephrectomy patients for localized clear cell RCC were evaluated from 2005-2017 to investigate preoperative CRP’s prognostic value on overall survival. Cohort was divided into 3 groups based on preoperative CRP (≤ 10, 10-100, > 100 mg/L). Kaplan-Meier curve and Cox proportional hazards models evaluated the predictive value of preoperative CRP in addition to established covariates. Results: Mean age was 59±12 years. 81 (11.6%) patients were deceased at the end of follow-up. T-stage distribution of cohort as follows: T1 = 444 (65%), T2 = 38 (6%), T3 = 197 (29%), and T4 = 4 (1%). Log Rank test of the Kaplan–Meier estimates of survival probability in RCC patients stratified by preoperative CRP revealed significant difference (p-value < 0.001). Per Cox models, high preoperative CRP values were associated with higher mortality (P < 0.001), higher T Stage (P < 0.001), Fuhrman Grade (P < 0.001), fat invasion (P < 0.001), and necrosis (P < 0.001). Multivariable model identified high preoperative CRP ( > 100) as an independent predictor of survival compared to low-to-normal (HR: 2.1, 95%CI: 1.00-4.23, p-value-0.05). 5-year survival of patients with CRP > 100 was 43%. Conclusions: Preoperative CRP could potentially be used as an independent predictor of overall survival post nephrectomy in patients with RCC. Higher CRP values are associated with higher mortality in such patients.

529 Background: In most settings median overall survival (OS) is longer for non-Hispanic whites relative to non-Hispanic blacks with metastatic renal cell carcinoma (mRCC). However, absence of nephrectomy has been a predictor of shorter OS for both groups. The primary objectives of this study were to define the reasons why patients with mRCC do not undergo nephrectomy and to correlate absolute contraindications to surgery with race and OS. Methods: Retrospective chart reviews of patients treated with targeted therapy for mRCC were conducted at the Winship Cancer Institute of Emory University and the AVAMC after obtaining institutional authorizations. Reasons for not undergoing nephrectomy were categorized as absolute, relative or no contraindication to nephrectomy. Descriptive statistics were employed along with Kaplan-Meier survival analysis. Results: See Table. The median OS (months) by nephrectomy status was 15.9 (6.8 – 24.7) vs. 41.8 (25.6 – 49.4), p value 0.0003, for patients at Emory with no nephrectomy vs. nephrectomy, respectively. The corresponding AVAMC values were 15.5 (8.5 – 29.5) vs. 45.2 (30.3 – 100.9), p value 0.0002. Conclusions: The number of patients with absolute contraindications to nephrectomy varied widely by race and institution, yet absence of nephrectomy was the predominant predictor of shorter OS in both settings.

682 Background: Lymph node (LN) metastases affect overall survival (OS) in pancreatic cancer (PC). However, a LN sampling threshold does not exist. We examined the impact of nodal sampling on overall survival (OS). Methods: Patients with Stage I-III PC ≥55 years old who underwent curative resection from 2004-2016 were identified from the National Cancer Database (NCDB). After adjusting for age, gender, grade, stage, and Charlson-Deyo score, multiple binomial logistic regression analyses assessed the impact of the LN ratio (LNR) on OS. LNR was defined as the number of positive LN over the number of LN examined. Regression analyses, a Cox-Regression, and a Kaplan-Meier survival curve assessed how many LN should be sampled. Results: A total of 13,673 patients, median age 69 years (55-90), were included. Most were Caucasian (86.6%) males with Charlson-Deyo scores ≤ 1 (90.3%) and moderately to poorly differentiated PC (90.1%). Median number of LN examined was 15 (1-75) with a median of 1 positive LN (0-35). As expected, increased number of positive LNs was associated with reduced OS, p < 0.001. After data normalization, an increasing LNR was associated with a 12-fold likelihood of death [OR: 11.9, p < 0.001 (CI 6.0, 23.7)]. Subsequent regression models established evaluation of ≥ 16 LNs as the greatest predictor of OS. A regression model evaluating < or ≥ 16 lymph nodes was performed to ascertain the effects of age, gender, ethnicity, grade, stage, and LN examined on OS. The logistic regression model correctly classified 74.5% of cases with a specificity of 99.6% (p < 0.001). Examination of < 16 LN, Caucasian race, grade, stage, and higher Charlson-Deyo scores were significantly associated with decreased OS. If ≥ 16 LNs were examined, patients had a 1.5-fold likelihood of better OS, p < 0.001 (CI 1.4, 1.6). An adjusted Cox Regression showed increased HR of 1.2, p < 0.001 (CI 1.1, 1.2) and an unadjusted Kaplan Meier survival curve predicted ≥ 16 LN examined are associated with an increase in OS of 2.8 months [log-rank: 32.0, p < 0.001]. Conclusions: Patients undergoing curative intent resection for PC should have adequate nodal sampling. Stratification of patients by LNR may provide useful information of OS. Examination of ≥ 16 LNs impacts OS in patients with Stage I-III PC.

589 Background: Recently, the De-Ritis ratio, defined as the ratio of preoperative aspartate aminotransferase (AST) to alanine aminotransferase (ALT), was shown to be an independent predictor of overall and recurrence-free survival in a European cohort with localized renal cell carcinoma (RCC). In this study, we perform an external validation of the De-Ritis ratio as a prognostic indicator in a distinct cohort of patients with localized and metastatic RCC. Methods: Patients that underwent nephrectomy for localized and metastatic RCC between 2001 and 2014 with available laboratory values within one week of surgery were queried from the Emory Nephrectomy Database. De-Ritis ratio of 1.2 was used to divide subjects into high and low subgroups. Using clinical follow-up data, prognostic value of the De-Ritis ratio was analyzed using the Kaplan-Meier method and Cox proportional regression models. Results: In a cohort of 451 patients, an elevated De-Ritis ratio (AST/ALT ≥ 1.2) was associated with significantly decreased overall survival (log-rank, p=0.0023) and recurrence-free survival (Log-rank, p=0.0395). On multivariate analysis, De-Ritis ratio was shown to be an independent and significant predictor of overall survival (HR=0.52, p=0.002) and recurrence-free survival (HR=0.47, p=0.014) as seen in Table. Conclusions: Elevated De-Ritis ratio (AST/ALT ≥ 1.2) is an independent and significant predictor of overall and recurrence-free survival and is capable of differentiating high-risk disease in patients with localized and metastatic RCC. These findings are consistent with a previous study investigating the prognostic value of the De-Ritis ratio in a European cohort, and further validates its prognostic ability in a geographically distinct cohort including patients who presented with metastatic disease [Table: see text]

1Q Gain

Abstract The gain of the 1q region, which is a recurrent chromosomal aberration in B lymphoproliferative disorder, has been reported one of the most common anomalies in Korean myelodysplastic patients. Recently, risk based application of hypomethylating agents or tailored therapy in MDS rely on the prognostic variables of International Prognostic Scoring System (IPSS). To investigate the possibility of 1q gain as a new prognostic marker, we evaluated the prognostic impact of 1q gain, along with comparison with IPSS variables. A total of 117 patients with newly diagnosed MDS between 1997 and 2007 at the Seoul National University Hospital were investigated. Fluorescence in situ hybridization (FISH) studies with 5 specific probe(EGR1 for 5q31 deletion, D7S522 for 7q31 deletion, CEP8, D20S108 for 20q12 deletion, LSI 1p36/1q25 for 1q gain) and conventional G-banding karyotyping were performed on bone marrow aspirates. Other laboratory findings, such as hemoglobin(Hb), absolute neutrophil count(ANC), platelet count, bone marrow blast percent and IPSS score, and clinical data were collected through the individual medical records. The median age was 54 years and the male-to-female ratio was 1.4. Using WHO classification, refractory anemia(RA) was 27.4% and the other subgroups as follows: RA with ringed sideroblast(RARS), 3.4%; refractory cytopenia with multilineage dysplasia(RCMD), 8.5%; RCMD with ringed sideroblasts(RCMD-RS), 0.9%; RA with excess blasts-1(RAEB-1), 26.5%; RAEB-2, 31.6%; and 5q- syndrome, 1.7%. Cytogenetic abnormalities by FISH and G-banding were detected in 58 patients (49.6%). Most frequent anomaly was trisomy 8 occuring in 28 patients(23.9% of the 117 patients, 48.3% of the 58 patients with clonal cytogenetic abnormalities). Gain of 1q was the second common anomalies seen in 18 patients (15.4%) and other anomalies were −7/del7q (13.7%), −5/del5q (13.7%), and del20q (2.6%). G-banding showed gain of 1q in 7 cases, additional 11 patients with gain of 1q were revealed by FISH only. Patients with 1q gain showed a poor survival (median survival 23 months; n=18) compared to patients without 1q gain (median survival 60 months; p=0.02). EGR1 and D7S522 deletion by FISH also had a shorter median survival (8 months vs. 60 months p=0.0001, 16 months vs. 60 months p=0.005). The initial platelet count and blast count were found to affect overall survival, whereas CEP8 FISH, D20S108 FISH, Hb and ANC did not. Our results show that gain of 1q is associated with an adverse clinical outcome and can be considered as a poor cytogenetic risk factor of IPSS. In the Western study, the prevalence of 1q gain was low because most studies report G-banding result only. But it may be increased up to 2.5 fold higher by using FISH analysis in combination with G-banding. A gain of 1q could be a candidate as an adverse prognostic marker in clinical practice, which could help for risk-adapted therapies. Figure 1.
