Background. The pretreatment albumin and globulin ratio (AGR) was an inflammation-associated factor which was related to the overall survival in various malignancies. The aim of this study was to evaluate the prognostic value of AGR in patients with gastric cancer. Method. This retrospective study included 862 cases pathologically diagnosed with gastric cancer. All patients were randomly divided into the testing group (431 cases) and validation group (431 cases). The relationships of AGR with clinicopathologic characteristics and prognosis were analyzed by Kaplan-Meier and Cox regression methods. Results. In the testing group, the median overall survival was 26.90 months and the cutoff value of AGR was 1.50 based on R language. Kaplan-Meier analysis showed that lower AGR was correlated with poorer overall survival. Multivariate analysis demonstrated that AGR was an independent prognostic factor for overall survival (HR: 0.584, 95% CI = 0.351–0.973, and p = 0.039). In the validation group, the median overall survival was 24.10 months. Lower AGR (≤1.50) also had a significantly poorer overall survival by Kaplan-Meier analysis. According to multivariate analysis, the AGR was also confirmed to be an independent prognostic factor for overall survival (HR: 0.578, 95% CI = 0.373–0.897, and p = 0.015). Conclusions. Our study suggested that the pretreatment AGR could be a prognostic biomarker for overall survival in patients with gastric cancer.

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.

Abstract Background: TCF7L2 gene is known as transcription factor 7-like 2 which has been identified as a novel transcription factor epithelial-mesenchymal transition (EMT) in tumor cells at 10q25.3. TCF7L2 may affect cancer progression and plays a central role in cancer proliferation, migration and invasion. However, its clinical and prognostic value have not been researched in glioma. The purpose of our study was to research TCF7L2 expression and evaluate the clinical value of prognosis.Method: We collected glioma specimens including low-grade glioma (n=46)and glioblastoma (n=51) from September 2015 to September 2017.Expression of TCF7L2 in 97 specimens were detected by quantitative real-time PCR (qRT-PCR).The chi-square test was applied to analyze the relationship between TCF7L2 expression and clinicopathological characteristics. The overall survival (OS) was analyzed by binary logistic regression analysis, the survival curves were drew by Kaplan-Meier. Univariate and multivariate analysis were utilized to analyze the relationship between prognosis and clinicopathological characteristics including TCF7L2 expression.RESULTS: Compared with low-grade glioma group, the expression of TCF7L2 was significantly increased (p<0.05). TCF7L2 overexpression was associated with large tumor volume (p=0.03), higher WHO grade (p=0.001), and recurrence (p=0.001). Moreover, Kaplan-Meier analysis proved that overexpressed TCF7L2 was related with poor OS (p< 0.05).The multivariate analysis suggested that TCF7L2 expression was an independent prognostic factor.CONCLUSIONS: Our research proved that TCF7L2 was over- expressed in glioblastoma, and, related with tumor prognosis, which, therefore, could be an independent prognostic factor for glioma patients.

Univariate and multivariate analysis were utilized to analyze the relationship between prognosis and clinicopathological characteristics including TCF7L2 expression.Results: Compared with the low-grade glioma group, the expression of TCF7L2 was significantly increased in the glioblastoma group (p = 0.001). TCF7L2 overexpression was associated with higher WHO grade (p = 0.001), isocitrate dehydrogenase (IDH) wild-type (p = 0.001), and lack of O(6)-methylguanine-DNA methyltransferase (MGMT) methylation (p = 0.001). Moreover, Kaplan-Meier analysis proved that overexpressed TCF7L2 was associated with poor OS (p = 0.010). The multivariate analysis suggested that TCF7L2 expression was an independent prognostic factor (p = 0.020).Conclusions: Our research proved that TCF7L2 was overexpressed in glioblastoma, and related with tumor long-term prognosis, which, therefore, could be an independent prognostic factor for glioma patients.

e16522 Background: Cs are commonly used in the treatment of mCRPC, because of their inhibitory effects on the secretion of ACTH and their palliative effects. Inhibition of ACTH results in downregulation of adrenal androgens. Cs may have a cytotoxic effect on prostate cancer cells, mediated in part by the downregulation of androgen receptors and the activation of glucocorticoid receptor-mediated signaling and downstream antiangiogenic activity. The rationale for adding Cs to D chemotherapy is for the management of symptoms and adverse events rather than for improving responses. D (without Cs) + ADT (androgen-deprivation therapy) vs ADT alone in castration-sensitive prostate cancer has resulted in significant increase in survival (NEJM, 2015). Cs has been reported to adversely influence OS during enzalutamide (NEJM, 2012). In the COU-AA-301 trial Cs use at baseline was an independent prognostic factor in multivariate analysis, but not in a stepwise selection model (JCO, 2013). Methods: We performed a retrospective analysis of 117 mCRPC pts treated with D. All pts had standard Cs premedication before D and 74 pts received prednisone 5 mg po BID, but 43 pts didn’t get continuous Cs therapy. Kaplan-Meier estimates and Cox regression model were used. Results: Pts characteristics were as follows: median age 66 yrs (range 48-81), Gleason score ≤6: 22pts, ≥7: 61pts. (34 NA). Altogether 1015 cycles of D were given, median 8 (range 2-27). Subsequent therapies were as follows: Abiraterone Acetate (AA) (75), Mitoxantrone (46), Xofigo (5), other chemotherapies (7), none (21). Pts receiving Cs had an inferior OS in all subgroups, although none was significant (Table). Only the Gleason score was an independent prognostic factor in multivariate analysis. Conclusions: Our data suggest, that D therapy withouth Cs is at least as effective as the combination. More data is neccesary to support the suspicion of negative influence of Cs on OS. Thus unnecesarry Cs treatment might be ommited. [Table: see text]

Abstract BACKGROUND Polymorphisms in interleukin-10 (IL-10) genes can influence immune responses that may affect the outcome of lymphoid neoplasms. METHODS We analyzed two single-nucleotide polymorphisms (−1082 and −3575) in the IL-10 promoter region in 472 consecutive non-immunessuppresed cases diagnosed with lymphoid neoplasms. Genotypes were tested for an association with overall survival and classical prognostic factors by multivariate analysis, adjusted for clinical characteristics and other confounders. Haplotypes were reconstructed using haplo.stats package and their implications analyzed in lymphoma survival by multivariate analysis. RESULTS In our series, patients with IL-10-3575AA genotype had a better overall survival (p= 0.002) for all lymphoid neoplasms as well as within the non-Hodgkin lymphoma patients (p=0.04). We also found that patients carrying the IL-10-1082GG genotype presented a better median overall survival when compared to genotypes IL-10-1082AA/AG. (p=0.05). When information on both genotypes were included in a multivariate analysis, IL-10-3575AA was the only genotype identified as an independent prognostic factor for survival (HR=0.2, 95%CI 0.05–0.92). Haplotype analysis showed that patients with A-G/A-G diplotype had a longer overall survival (p=0.0042) and it appeared to be an independent prognostic factor for survival (HR:0.26; 95%CI 0.08–0.83). CONCLUSIONS IL-10-3575AA and IL-10-1082GG genotypes, together with A-G/A-G diplotype were identified as markers of a favorable lymphoma survival.

Abstract Purpose The aim of this study was to determine if the prognostic value of the preoperative neutrophil-to-lymphocyte ratio (NLR) could be modified by the presence of postoperative complications (POC) and their severity in patients with gastric adenocarcinoma resected with curative intent. Methods A retrospective study based on a prospective database of patients with resectable gastric adenocarcinoma treated with radical intention (R0) between January 1998 and February 2012. The primary endpoint was overall survival according to preoperative peripheral blood NLR and postoperative complications. Clinicopathological variables, preoperative blood tests, POC and its severity (Clavien–Dindo classification), type of POC (infectious or not infectious) and mortality were registered. A univariate and multivariate analysis (step forward Cox regression) was performed. The Kaplan–Meier method was used to assess overall survival. Results The 147 patients with gastric cancer who had undergone radical resection were included from an initial cohort of 209 patients. Univariant analysis: type of surgery, pT, pN, postoperative complications (Clavien–Dindo ≥ 3) and preoperative NLR ≥ 2.4 were significantly associated with survival (p < 0.05). Patients with POC showed worse long-term survival (p = 0.000), with no difference (p = 0.867) between infectious or non-infectious POC. NLR ≥ 2.4 was associated with infectious POC (p < 0.001). Patients with preoperative NLR ≥ 2.4 (p = 0.02) had a worse prognosis. Multivariate analysis: pN (p < 0.001), postoperative complications (p < 0.001) (HR 3.04; 95% CI: 1.97–4.70) and NLR ≥ 2.4 (p = 0.04) (HR = 1.55; 95% CI: 1.02–2.3) were independent prognostic factors. Conclusion The preoperative inflammatory state of patients with gastric cancer measured by NLR behaves as an independent prognostic factor, even in patients with POC.

Abstract Purpose Platelet-to-lymphocyte ratio (PLR) was established showing the poor prognosis in several diseases, such as malignancies and cardiovascular diseases. But limited study has been conducted about the prognostic value of PLR on the long-term renal survival of patients with Immunoglobulin A nephropathy (IgAN). Methods We performed an observational cohort study enrolling patients with biopsy-proven IgAN recorded from November 2011 to March 2016. The definition of composite endpoint was eGFR decrease by 50%, eGFR < 15 mL/min/1.73 m2, initiation of dialysis, or renal transplantation. Patients were categorized by the magnitude of PLR tertiles into three groups. The Kaplan–Meier curves and multivariate Cox models were performed to determine the association of PLR with the renal survival of IgAN patients. Results 330 patients with a median age of 34.0 years were followed for a median of 47.4 months, and 27 patients (8.2%) had reached the composite endpoints. There were no differences among the three groups (PLR < 106, 106 ≤ PLR ≤ 137, and PLR > 137) in demographic characteristics, mean arterial pressure (MAP), proteinuria, and estimated glomerular filtration rate (eGFR) at baseline. The Kaplan–Meier curves showed that the PLR > 137 group was significantly more likely to poor renal outcomes than the other two groups. Using univariate and multivariate cox regression analyses, we found that PLR > 137 was an independent prognostic factor for poor renal survival in patients with IgAN. Subgroup analysis revealed that the PLR remained the prognostic value for female patients or patients with eGFR less than 60 mL/min/1.73 m2. Conclusions Our results underscored that baseline PLR was an independent prognostic factor for poor renal survival in patients with IgAN, especially for female patients or those patients with baseline eGFR less than 60 mL/min/1.73 m2.

Background: The prognostic role of the translational factor, elongation factor-1 alpha 1 (EEF1A1), in colon cancer is unclear. Objectives: The present study aimed to investigate the expression of EEF1A in tissues obtained from patients with stage II and III colon cancer and analyze its association with patient prognosis. Methods: A total of 281 patients with colon cancer who underwent curative resection were analyzed according to EEF1A1 expression. Results: The five-year overall survival in the high-EEF1A1 group was 87.7%, whereas it was 65.6% in the low-EEF1A1 expression group (hazard ratio (HR) 2.47, 95% confidence interval (CI) 1.38–4.44, p = 0.002). The five-year disease-free survival of patients with high EEF1A1 expression was 82.5%, which was longer than the rate of 55.4% observed for patients with low EEF1A1 expression (HR 2.94, 95% CI 1.72–5.04, p < 0.001). Univariate Cox regression analysis indicated that age, preoperative carcinoembryonic antigen level, adjuvant treatment, total number of metastatic lymph nodes, and EEF1A1 expression level were significant prognostic factors for death. In multivariate analysis, expression of EEF1A1 was an independent prognostic factor associated with death (HR 3.01, 95% CI 1.636–5.543, p < 0.001). EEF1A1 expression was also an independent prognostic factor for disease-free survival in multivariate analysis (HR 2.54, 95% CI 1.459–4.434, p < 0.001). Conclusions: Our study demonstrated that high expression of EEF1A1 has a favorable prognostic effect on patients with colon adenocarcinoma.

Introduction: The aim of the study was to evaluate impact of the systemic immune-inflammation index (SII) on prognosis and survival within the International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) score groups. Methods: The records of 187 patients with metastatic renal cell carcinoma (RCC) were reviewed retrospectively. The SII was calculated as follows: SII = Neutrophil × Platelet/Lymphocyte. The patients were categorized into 2 groups based on a median SII of 730 (×109 per 1 L) as SII low (<730) and SII high (≥730). The Kaplan-Meier method was used for survival analysis and a Cox regression model was utilized to determine independent predictors of survival. Results: The median age was 61 years (range: 34–86 years). Kaplan-Meier tests revealed significant differences in survival between the SII-low and SII-high levels (27.0 vs. 12.0 months, respectively, p < 0.001). The Cox regression model revealed that SII was an independent prognostic factor. The implementation of the log-rank test in the IMDC groups according to the SII level provided the distinction of survival in the favorable group (SII low 49.0 months vs. SII high 11.0 months, p < 0.001), in the intermediate group (SII low 26.0 vs. SII high 15.0 months, p = 0.007), and in the poor group (SII low 19.0 vs. SII high 6.0 months, p = 0.019). Conclusion: The SII was an independent prognostic factor and provided significant differences in survival for the favorable, intermediate, and poor IMDC groups. Thus, the SII added to the IMDC score may be clinically beneficial in predicting survival.

Abstract Abstract 5018 Background: Obesity was associated with a more than 2-fold greater risk of myelodysplastic syndrome (MDS) in a recent epidemiological study (Ma et al, Am J Epidemiol. 2009 June 15; 169(12): 1492–1499). The impact of obesity on outcome of disease in patients with an established diagnosis of MDS has not been studied. We examined the prognostic value of obesity in a large cohort of lower risk MDS patients treated at the Moffitt Cancer Center (MCC). Methods: Data were collected retrospectively from the Moffitt Cancer Center (MCC) MDS database and individual charts reviewed. The primary objective was to evaluate the impact of obesity on overall survival (OS) in lower risk patients with MDS. Patients with low or intermediate-1 (int-1) risk disease by International Prognostic Scoring System (IPSS) were included. Obesity was defined as a body mass index (BMI) ≥ 30 (Standard definition) measured at time of referral to MDS program at MCC. Patients were divided into two groups according to BMI ≥ 30 or BMI < 30. All analyses were conducted using SPSS version 19.0. Chi square and independent t-test were used to compare baseline characteristics between the 2 groups for categorical and continuous variables, respectively. The Kaplan–Meier method was used to estimate median overall survival. Log rank test was used to compare Kaplan–Meier survival estimates between two groups. Cox regression was used for multivariable analysis. Results: Between January 2001 and December 2009, 479 low/int-1 IPSS risk MDS patients were included. Among those, 132 (27.6%) had BMI ≥ 30 and 325 (67.8%) had BMI <30; BMI was missing in 22 patients (4.6%). The baseline characteristics between the two groups were comparable. No difference was noted in mean age, WHO subtype, karyotype, MD Anderson risk model group, red blood cell transfusion dependency (RBC-TD), or serum ferritin (Table-1). The median OS was 59 mo (95%CI 48–70) in patients with BMI <30 compared to 44 (95%CI 38–50) in patients with BMI ≥ 30. (p=0.03). There was no difference in rate of AML transformation according to BMI, 12.9% and 15.7% respectively for BMI ≥ 30 and BMI <30. (P=0.3). In Cox regression analysis obesity predicted inferior OS (Hazard ratio (HR) 1.7 (95%CI 1.15–2.4) (P=0.007) after adjustment for age, MD Anderson risk group, serum ferritin, RBC-TD, use of hypomethylating agents and tobacco use. Conclusion: Our data suggest that obesity is an independent adverse prognostic factor for OS in patients with lower risk MDS. Obesity may be associated with other comorbidities and metabolic dearrangements that contribute to the pathogenesis of the underlying disease. Disclosures: No relevant conflicts of interest to declare.
