Purpose: The prognostic evaluation of glioma recurrence patients is important in the therapeutic management. We investigated the prognostic value of 11C-methionine PET-CT (MET-PET) dynamic and semiquantitative parameters in patients with suspected glioma recurrence. Methods: Sixty-seven consecutive patients who underwent MET-PET for suspected glioma recurrence at MR were retrospectively included. Twenty-one patients underwent static MET-PET; 46/67 underwent dynamic MET-PET. In all patients, SUVmax, SUVmean and tumour-to-background ratio (T/B) were calculated. From dynamic acquisition, the shape and slope of time-activity curves, time-to-peak and its SUVmax (SUVmaxTTP) were extrapolated. The prognostic value of PET parameters on progression-free (PFS) and overall survival (OS) was evaluated using Kaplan–Meier survival estimates and Cox regression. Results: The overall median follow-up was 19 months from MET-PET. Recurrence patients (38/67) had higher SUVmax (p = 0.001), SUVmean (p = 0.002) and T/B (p < 0.001); deceased patients (16/67) showed higher SUVmax (p = 0.03), SUVmean (p = 0.03) and T/B (p = 0.006). All static parameters were associated with PFS (all p < 0.001); T/B was associated with OS (p = 0.031). Regarding kinetic analyses, recurrence (27/46) and deceased (14/46) patients had higher SUVmaxTTP (p = 0.02, p = 0.01, respectively). SUVmaxTTP was the only dynamic parameter associated with PFS (p = 0.02) and OS (p = 0.006). At univariate analysis, SUVmax, SUVmean, T/B and SUVmaxTTP were predictive for PFS (all p < 0.05); SUVmaxTTP was predictive for OS (p = 0.02). At multivariate analysis, SUVmaxTTP remained significant for PFS (p = 0.03). Conclusion: Semiquantitative parameters and SUVmaxTTP were associated with clinical outcomes in patients with suspected glioma recurrence. Dynamic PET-CT acquisition, with static and kinetic parameters, can be a valuable non-invasive prognostic marker, identifying patients with worse prognosis who require personalised therapy.

Abstract We aimed to investigate the prognostic value of the metabolic parameters of 18F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) in classical rectal adenocarcinoma (CRAC). We retrospectively reviewed 149 patients with CRAC who underwent preoperative 18F-FDG PET/CT at initial diagnosis followed by curative surgical resection. 18F-FDG PET/CT metabolic parameters including maximum standardized uptake value (SUVmax), metabolic tumour volume (MTV), and total lesion glycolysis (TLG) for disease-free survival (DFS) and overall survival (OS) were evaluated for prognostic significance by univariate and multivariate analyses, along with conventional risk factors including pathologic T (pT) stage, lymph node (LN) metastasis, lymphovascular invasion (LVI), perineural invasion (PNI), and preoperative carcinoembryonic antigen (CEA) level. On univariate analysis, high pT stage, positive LN metastasis, LVI, PNI, MTV, and TLG were significant prognostic factors affecting DFS (all P < 0.05), while CEA level, high pT stage, positive LN metastasis, LVI, PNI, MTV, and TLG affected OS (all P < 0.05). On multivariate analysis, positive LN metastasis, LVI, MTV, and TLG were independent prognostic factors affecting DFS (all P < 0.05), while CEA level, positive LN metastasis, and MTV affected OS (all P < 0.05). Thus, MTV and TLG are independent prognostic factors for DFS and OS in CRAC patients.

e15131 Background: CEA is regarded as the marker of choice for monitoring patients with colorectal cancer (CRC), but the value of using CA19-9 is insufficient. The prognostic value of serum CA19-9 in combination with CEA was evaluated in patients with metastatic CRC (mCRC) before first (1) and third line therapy (3LT). Methods: From April 2004 to May 2015, pretreatment serum samples were collected from 160 and 255 patients with mCRC before 1LT and 3LT, respectively. Median age was 64 [range 33-87] and male/female ratio 243(59%)/172(41%). Serum CA19-9 was determined by routine chemiluminescent immunometric assay (normal range 0-37 KU/l). Progression-free survival (PFS) and overall (OS) crude, adjusted hazard ratios (HR) and corresponding 95% confidence intervals (CIs) were estimated using Cox regression analysis. CA19-9 and CEA were included as log2-transformed continuous variables and adjustment included mutually between CA19-9 and CEA in addition to primary tumor location, sex and age. Results: In 3LT median pretreatment CEA levels were higher than in 1LT (59 µg/l [IQR 14-288] vs. 23[6-153] P < 0.01) while CA19-9 values were similar (112 KU/l [23-626] vs. 98[19-390]). In patients treated with 3LT univariate analysis showed that high levels of CA19-9 and CEA were associated with short PFS (CA19-9: HR = 1.06, 95% CI 1.02-1.10, P < 0.01; CEA: HR = 1.05, 1.00-1.09, P = 0.04). In 1LT neither CA19-9 nor CEA were significantly associated with PFS. In a multivariate analysis, none of the biomarkers were significantly associated with PFS. In patients treated with 3LT univariate analysis showed that high levels of CA 19-9 and CEA were associated with short OS (CA19-9: HR = 1.11, 1.07-1.16, P < 0.01; CEA: HR = 1.1, 1.06-1.16, P < 0.01). In patients treated with 1LT high levels of CA-19-9 but not CEA was significantly associated with a shorter OS (HR = 1.07, 1.00-1.14, P = 0.04). In 3LT multivariate analyses showed that high levels of CA19-9 and CEA were the only factors associated with a shorter OS (CA19-9: HR = 1.08, 1.03-1.13, P < 0.01; CEA: HR = 1.07, 1.01-1.14, P < 0.01), while there was no significant association to OS in 1LT. Conclusions: Serum CA19-9 may be a valuable prognostic biomarker in combination with CEA in mCRC patients receiving third line therapy.

591 Background: To investigate the prognostic value of the pretreatment inflammatory characteristics on treatment response and survival. Methods: We included 151 patients with metastatic renal cell carcinoma (mRCC) Patients’ charts were retrospectively analyzed for their clinical, pathological and demographic features. Systemic immune inflammation index (SII) cut off is estimated with median value. Overall survival (OS) was estimated by Kaplan-Meier method for univariate analysis and Cox-regression for multivariate analysis. Results: In high SII group (SII > 844) overall survival is 11 months and in low SII group (SII < 844) overall survival is 22 months (p = 0,008). Median OS is lower in the hypercalcemic group (7 months vs.18 months, P = 0,013). In patients with anemia and thrombocytosis, OS is lower (41 months vs. 13 months p = 0,001 and 6 months vs. 18 months p = 0,01). In multivariate analysis, anemia, SII, and ECOG performance status were able to predict OS (HR = 2,69, HR = 2,04, HR = 2,57) Conclusions: In patients with mRCC, SII may have a prognostic value and higher score may related with decreased overall survival.

AbstractIn glioma patients, complete resection of the contrast-enhancing portion is associated with improved survival, which, however, cannot be achieved in a considerable number of patients. Here, we evaluated the prognostic value of O-(2-[18F]-fluoroethyl)-L-tyrosine (FET) PET in not completely resectable glioma patients with minimal or absent contrast enhancement before temozolomide chemoradiation. Dynamic FET PET scans were performed in 18 newly diagnosed patients with partially resected (n = 8) or biopsied (n = 10) IDH-wildtype astrocytic glioma before initiation of temozolomide chemoradiation. Static and dynamic FET PET parameters, as well as contrast-enhancing volumes on MRI, were calculated. Using receiver operating characteristic analyses, threshold values for which the product of paired values for sensitivity and specificity reached a maximum were obtained. Subsequently, the prognostic values of FET PET parameters and contrast-enhancing volumes on MRI were evaluated using univariate Kaplan–Meier and multivariate Cox regression (including the MTV, age, MGMT promoter methylation, and contrast-enhancing volume) survival analyses for progression-free and overall survival (PFS, OS). On MRI, eight patients had no contrast enhancement; the remaining patients had minimal contrast-enhancing volumes (range, 0.2–5.3 mL). Univariate analyses revealed that smaller pre-irradiation FET PET tumor volumes were significantly correlated with a more favorable PFS (7.9 vs. 4.2 months; threshold, 14.8 mL; P = 0.012) and OS (16.6 vs. 9.0 months; threshold, 23.8 mL; P = 0.002). In contrast, mean tumor-to-brain ratios and time-to-peak values were only associated with a longer PFS (P = 0.048 and P = 0.045, respectively). Furthermore, the pre-irradiation FET PET tumor volume remained significant in multivariate analyses (P = 0.043), indicating an independent predictor for OS. Our results suggest that pre-irradiation FET PET parameters have a prognostic impact in this subgroup of patients.

Background. Although recently challenged, systemic inflammatory response syndrome (SIRS) criteria are still commonly used in daily practice to define sepsis. However, several factors in liver cirrhosis may negatively impact its prognostic ability. Goals. To investigate the factors associated with the presence of SIRS, the characteristics of SIRS related to infection, and its prognostic value among patients hospitalized for acute decompensation of cirrhosis. Study. In this cohort study from two tertiary hospitals, 543 patients were followed up, up to 90 days. Data collection, including the prognostic models, was within 48 hours of admission. Results. SIRS was present in 42.7% of the sample and was independently associated with upper gastrointestinal bleeding (UGB), ACLF, infection, and negatively related to beta-blockers. SIRS was associated with mortality in univariate analysis, but not in multiple Cox regression analysis. The Kaplan–Meier survival probability of patients without SIRS was 73.0% and for those with SIRS was 64.7%. The presence of SIRS was not significantly associated with mortality when considering patients with or without infection, separately. Infection in SIRS patients was independently associated with Child-Pugh C and inversely related to UGB. Among subjects with SIRS, mortality was independently related to the presence of infection, ACLF, and Child-Pugh C. Conclusions. SIRS was common in hospitalized patients with cirrhosis and was of no prognostic value, even in the presence of infection.

e18521 Background: Identification of biomarkers that can be used for the prognostic evaluation of NSCLC patients is important. The aim of this study was to evaluate the potential prognostic value of XRCC1, ERCC1, ERCC2 and, TP53 SNPs in completely resected NSCLC patients. Methods: In total 130 patients, who had been surgically treated for NSCLC between 2000 and 2012, were included in this study. Analysis of SNPs from peripheral blood cells was performed by polymerase chain reaction. XRCC1 Arg399Gln, ERCC1 Asn118Asn, ERCC2 Lys751Gln and, TP53 Arg72Pro polymorphisms were evaluated in conjunction with clinical and pathological parameters and survival. Kaplan-Meier method and Cox regression analysis were used. Results: In the univariate analysis for disease free survival (DFS) post operative stage (HR,0.50; 95%CI, 0.26-0.96; P=0.03), ERCC2 genotype (HR, 2.47; 95%CI, 1.28-4.78; P=0.007) and PET-CT staging (HR, 0.27;95%CI, 0.14-0.52; P<0.001) were significant parameters. Adjuvant chemotherapy, age and the other SNPs were not significant. In the multivariate analysis post operative stage (HR, 0.40;95%CI, 0.20-0.81; P=0.01), ERCC2 genotype (HR, 2.66;95%CI, 1.35-5.27; P=0.005), PET-CT staging (HR, 0.24;95%CI, 0.12-0.47; P<0.001) retained their significance. The median DFS was 56.5 months (95%CI, 24.6-88.4 months) for the ERCC2 mutant (TT) and heterozygote (GT) genotypes, and 28.3 months (95%CI, 20.8-35.8 months) for the ERCC2 normal (GG) genotype (P=0.005). Conclusions: In addition to stage and PET-CT staging, ERCC2 genotype independently predicted DFS in resected NSCLC patients. Future prospective studies are needed for the further evaluation of potential prognostic SNPs in resected NSCLC.

e15060 Background: The prognostic value of serum IL-6, YKL-40 and CEA before first (1) and third line therapy (3LT) in metastatic colorectal cancer (mCRC) is lacking and was evaluated in this study. Methods: From 2004 to 2015 serum samples were collected from 160 and 255 patients with mCRC before 1LT and 3LT, respectively. Median age was 64 years (range 33-87) and male/female ratio 243(59%)/172(41%). Serum IL-6 (R&D, UK) and YKL-40 (Quidel, USA) were determined by ELISA. Progression-free (PFS) and overall survival (OS), crude and adjusted hazard ratios (HR) and corresponding 95% confidence intervals (CI) were estimated with Cox regression analysis. CEA, IL-6 and YKL-40 were included as log2-transformed continuous variables with mutual adjustment between CEA, IL-6 and YKL-40, primary tumor location, sex and age. Results: In 3LT IL-6, YKL-40 and CEA levels were higher (P < 0.001) than in 1LT (IL-6: 9.5 pg/ml [IQR4.2-18.5] vs. 4.6 [2.5-10.5]; YKL-40: 140 ng/ml [77-272] vs. 101 [62-172]; and CEA: 59 ug/l [14-288] vs. 23[5.8-153]). In 3LT univariate analysis showed that increased levels of IL-6, YKL-40 and CEA were associated with shorter PFS (IL-6: HR = 1.19, 95% CI 1.07-1.31, P < 0.01; YKL-40: HR = 1.13, 1.04-1.24, P = 0.01; CEA: HR = 1.05, 1.00-1.09, P = 0.04). In 1LT only high IL-6 was associated with shorter PFS (HR = 1.09, 1.01-1.17, P = 0.03). In a multivariate analysis only high IL-6 was significantly associated with shorter PFS in 3LT (HR = 1.15, 1.03-1.29, P < 0.01) and none of the biomarkers in 1LT. In 3LT univariate analysis showed that increased levels of all 3 biomarkers were associated with a shorter OS (IL-6: HR = 1.36, 1.23-1.51, P < 0.01; YKL-40: HR = 1.21, 1.10-1.33, P < 0.01; CEA: HR = 1.11, 1.06-1.16, P < 0.01). In 1LT high levels of IL-6 (HR = 1.17, 1.08-1.27, P < 0.01) and YKL-40 (HR = 1.18, 1.00-1.38, P = 0.05), but not CEA, were associated with short OS. In 3LT the multivariate analysis showed that both higher IL-6 (HR = 1.34, 1.20-1.50, P < 0.01) and CEA (HR = 1.09, 1.03-1.14, P < 0.01), but not YKL-40 were significantly associated with a shorter OS. In 1LT only higher IL-6 was associated with a shorter OS (HR = 1.19, 1.08-1.31, P < 0.01) Conclusions: Serum IL-6 and YKL-40 may be useful prognostic biomarkers in combination with CEA in patients with mCRC

Abstract Background To date, no predictive or prognostic molecular biomarkers except BRCA mutations are clinically established for epithelial ovarian cancer (EOC) despite being the deadliest gynecological malignancy. Aim of this biomarker study was the analysis of DNA methylation biomarkers for their prognostic value independent from clinical variables in a heterogeneous cohort of 203 EOC patients from two university medical centers. Results The marker combination CAMK2N1/RUNX3 exhibited a significant prognostic value for progression-free (PFS) and overall survival (OS) of sporadic platinum-sensitive EOC (n = 188) both in univariate Kaplan–Meier (LogRank p < 0.05) and multivariate Cox regression analysis (p < 0.05; hazard ratio HR = 1.587). KRT86 methylation showed a prognostic value only in univariate analysis because of an association with FIGO staging (Fisher’s exact test p < 0.01). Thus, it may represent a marker for EOC staging. Dichotomous prognostic values were observed for KATNAL2 methylation depending on BRCA aberrations. KATNAL2 methylation exhibited a negative prognostic value for PFS in sporadic EOC patients without BRCA1 methylation (HR 1.591, p = 0.012) but positive prognostic value in sporadic EOC with BRCA1 methylation (HR 0.332, p = 0.04) or BRCA-mutated EOC (HR 0.620, n.s.). Conclusion The retrospective analysis of 188 sporadic platinum-sensitive EOC proved an independent prognostic value of the methylation marker combination CAMK2N1/RUNX3 for PFS and OS. If validated prospectively this combination may identify EOC patients with worse prognosis after standard therapy potentially benefiting from intensive follow-up, maintenance therapies or inclusion in therapeutic studies. The dichotomous prognostic value of KATNAL2 should be validated in larger sample sets of EOC.

Primary glioblastoma (GBM), IDH-wildtype, especially with multifocal appearance/growth (mGBM), is associated with very poor prognosis. Several clinical parameters have been identified to provide prognostic value in both unifocal GBM (uGBM) and mGBM, but information about the influence of radiological parameters on survival for mGBM cohorts is scarce. This study evaluated the prognostic value of several volumetric parameters derived from magnetic resonance imaging (MRI). Data from the Department of Neurosurgery, Leipzig University Hospital, were retrospectively analyzed. Patients treated between 2014 and 2019, aged older than 18 years and with adequate peri-operative MRI were included. Volumetric assessment was performed manually. One hundred and eighty-three patients were included. Survival of patients with mGBM was significantly shorter (p < 0.0001). Univariate analysis revealed extent of resection, adjuvant therapy regimen, residual tumor volume, tumor necrosis volume and ratio of tumor necrosis to initial volume as statistically significant for overall survival. In multivariate Cox regression, however, only EOR (for uGBM and the entire cohort) and adjuvant therapy were independently significant for survival. Decreased ratio of tumor necrosis to initial tumor volume and extent of resection were associated with prolonged survival in mGBM but failed to achieve statistical significance in multivariate analysis.
