Recurrence Group

Small bowel neuroendocrine tumors (SBNET) account for most gastrointestinal neuroendocrine tumors. Patients often present with late-stage disease; however, there is little information regarding factors that contribute to recurrence. Database review identified 301 patients diagnosed with SBNET between 1990 and 2013. Univariate analysis included patients who underwent complete resection. Survival was estimated by the Kaplan–Meier method. A total of 147 patients met study criteria. Average age was 60 years (range 21–91); 49 per cent were male. Thirty-seven (25.3%) patients had laparoscopic resection, and 29 (19.9%) patients had only small bowel disease, whereas 108 (72.6%) had nodal metastasis. Five-year overall and disease-free survival were 97.5 and 73.5 per cent. Forty-seven (32%) patients had recurrence. The recurrence group was more likely to have an open operation (59.6 vs 32%, P < 0.01), mesenteric invasion, or lymphatic metastasis (87.2 vs 67%, P < 0.01) compared with the no-recurrence group. Cox regression analysis showed that variables associated with recurrence included nodal disease (HR 9.06, P = 0.03), lymphovascular invasion (LVI) (3.95, P < 0.01), perineural invasion (PNI) (3.48, P < 0.01), and mesenteric involvement (3.77, P = 0.03). Patients with SBNET presenting with nodal metastasis, mesenteric involvement, LVI, or PNI have a higher risk of recurrence. Closer surveillance should be considered after operative resection.

Extrahepatic Metastases

The aim of the research was to investigate prognostic factors in patients with resected colorectal liver metastases (CLMs) after biological and chemotherapy, which made initially unresectable disease suitable for resection. Sixty-six patients with resected CLMs, operated after induction bio-chemotherapy with bevacizumab + FOLFOX4, treated at the Clinic of Oncology, Clinical Center Niš from 2010 - 2017 were included. Disease-free survival (DFS) and overall survival (OS) were estimated using the Kaplan-Meier method and compared using the log-rank test according to demographic characteristics, characteristics of the disease and the treatment. A univariate COX regression analysis was performed. In patients with up to 4 CLMs, DFS was significantly longer than in patients with five or more metastases (18,384 v.s. 6,85 months; p < 0,001). Significantly longer OS was present in patients with up to four CLMs than in those with five or more CLMs (44,687 v.s. 29,723 months; p=0,006) and in patients without extrahepatic disease (41,71 v.s. 23,283 months; p=0,012). In the univariate analysis, five or more CLMs were predictors of poorer DFS (HR 3,989; 95% CI 1,055 - 15,087; p = 0,042), whereas the absence of extrahepatic disease was a predictor of better OS (HR 0,122; 95% CI 0,017 - 0,869; p = 0,036). Results of this research are in concordance with previous larger studies in patients with resected CLMs. The number of hepatic and the presence of extrahepatic metastases are prognostic parameters in patients with resected CLM after conversion bio-chemotherapy.

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.

Aim: This study aimed to develop an effective risk predictor for patients with stage II and III colorectal cancer (CRC). Materials & methods: The prognostic value of p-mTOR (Ser2448) levels was analyzed using Kaplan–Meier survival analysis and Cox regression analysis. Results: The levels of p-mTOR were increased in CRC specimens and significantly correlated with poor prognosis in patients with stage II and III CRC. Notably, the p-mTOR level was an independent poor prognostic factor for disease-free survival and overall survival in stage II CRC. Conclusion: Aberrant mTOR activation was significantly associated with the risk of recurrence or death in patients with stage II and III CRC, thus this activated proteins that may serve as a potential biomarker for high-risk CRC.

408 Background: Current surveillance guidelines regarding follow up of patients with resected pancreatic neuroendocrine tumors (PNETs) are based on limited data, and there have been few studies evaluating recurrence risk in such patients. We assessed disease-free survival (DFS) in a large, multi-institutional cohort of patients with resected PNETs. Methods: Patients with surgically resected, non-metastatic PNETs between 1990-2017 were identified using institutional databases at three institutions: Mount Sinai Hospital, Dana-Farber Cancer Institute, and University of Pennsylvania. Recurrence date was defined as the imaging date documenting first recurrence (n = 56); if an imaging date was not available, then July 1 of that year was used in calculations (n = 9). Kaplan-Meier analysis was used to estimate DFS; multivariate Cox regression analysis was used to assess DFS adjusted for patient and disease-related characteristics, including tumor stage and grade. Results: We identified a total of 418 patients with surgically resected, non-metastatic PNETs between 1990-2017. Of these patients, 299 patients had complete stage and tumor grade information and were used for subsequent analysis. Patients were 48.6% male with a median age of 57.5 years at time of surgery. The distribution of AJCC stage and grade was as follows: 170 (56.9%) patients were stage I, 129 (43.1%) were stage II; 167 (55.9%) had grade 1, 121 (40.5%) had grade 2, and 11 (3.7%) had grade 3 tumors. Median follow-up was 2.6 years (interquartile range = 4.2); during this time, 65 (21.7%) patients developed disease recurrence. After adjusting for potential confounders, patients with more advanced stage and higher tumor grade were significantly more likely to develop disease recurrence (Hazard Ratio (HR): 6.9, 95% CI: 2.5-19.1 for stage II; HR 4.0 (1.7-9.5) for grade 2; HR 2.6 (0.4-17.8) for grade 3). Both higher stage and tumor grade were associated with decreased DFS (p < 0.0001 for both). Conclusions: In surgically resected PNETs, with a median follow-up time of 2.6 years, both higher stage and higher grade are associated with decreased DFS. Further follow up of this cohort is planned.

e17130 Background: Obesity is associated with worse patients’ survival in several cancer entities. Vulvar cancer as well as obesity show increasing incidence over the last years. The influence of obesity on prognosis of vulvar cancer patients is not clear. However, knowledge about this may have consequences on prevention, treatment, and follow-up. Methods: This is an analysis of the large AGO-CaRE-1 study. Patients suffering from squamous cell vulvar cancer (UICC stage IB and higher), treated in 29 cancer centers between 1998 and 2008, were categorized in a database, in order to analyze treatment patterns and prognostic factors in a retrospective setting. Results: In total, 849 patients with documented height and weight were divided into two groups depending on their body mass index (BMI, < 30 vs. ≥30 kg/m²). There was no difference in the baseline variables (age, tumor diameter, depth of infiltration, tumor stage, nodal invasion, tumor grade) between both groups (p > 0.05). However, we identified differences regarding ECOG status and preexistent comorbidities (cardiovascular, dementia) towards healthier patients with BMI < 30 kg/m². Treatment variables (R0 resection, chemotherapy, radiotherapy, continuation of adjuvant therapy) did not differ (p > 0.05). Patients with BMI ≥30 kg/m² underwent radical vulvectomy more often (61.1 % vs. 51.8%, p = 0.042). During follow-up, there was a higher recurrence rate in the group having a BMI ≥30 kg/m² (43.4%, vs. 28.3%, p < 0.01) due to an increased rate of local recurrences (33.3% vs. 18.5%, p < 0.01). The rate of groin and distant recurrences was similar between both groups (p > 0.05). Noteworthy, we observed a significantly shorter disease free survival (DSF) of the obese patients in univariate analysis (HR 1.362, 95%CI 1.093-1.696, p = 0.006). Even in multivariate Cox-regression analysis including age, ECOG, tumor stage, type of surgery, nodal invasion, tumor grade, and comorbidities patients with BMI ≥30 kg/m² had a significantly shorter DFS (HR 1.811, 95%CI 1.005-3.262, p = 0.048). Conclusions: In this first large study about the association between obesity and prognosis of vulvar cancer patients, we observed that a BMI ≥30kg/m² was associated with shorter DFS, mainly attributed to a higher risk for local recurrence.

Aims To evaluate the prognostic value of vascular endothelial growth factor (VEGF), platelet-derived growth factor receptor-alpha (PDGFR-α) and beta (PDGFR-β) expression in patients with hepatocellular carcinoma (HCC). Methods The expression of PDGFR-α, PDGFR-β and VEGF in 63 HCC patients who underwent curative resection was examined by immunohistochemistry (IHC). The correlations between the expression of these biomarkers and the clinicopathological characteristics were analyzed. Patient survival was analyzed by univariate analysis and Cox proportional hazards model. Results Univariate survival analysis showed that PDGFR-α or PDGFR-β overexpression was of no prognostic significance in predicting disease-free survival (DFS) and overall survival (OS) (p>0.05), while VEGF overexpression and PDGFR-α/PDGFR-β/VEGF coexpression were significantly correlated with worse DFS and poorer OS in HCC patients (P<0.05). More importantly, PDGFR-α/PDGFR-β/VEGF coexpression was an independent prognostic marker for poor survival as indicated by multivariate Cox regression analysis (DFS, hazard ratio 3.122, p=0.001; OS, hazard ratio 4.260, p=0.000). Conclusions Coexpression of PDGFR-α, PDGFR-β and VEGF could be considered an independent prognostic biomarker for predicting DFS and OS in HCC patients. This result could be used to identify patients at a higher risk of tumor recurrence and poor prognosis, and help to select therapeutic schemes for the treatment of HCC.

Abstract Glioblastoma (GBM) is the most common and deadly tumor in the central nervous system. Recent studies illuminated that long noncoding RNAs (lncRNAs) serve as competitive endogenous RNAs (ceRNAs) and play an important role in GBM by regulating immune responses. Here, GBM datasets from TCGA database were analyzed to obtain 356 significantly differentially expressed lncRNAs (DE-lncRNAs), 4951 DE-mRNAs, and 34 DE-miRNAs in GBM, respectively. For mRNAs, 369 DE-mRNAs were identified as immune-related genes in Immport database. For DE-lncRNAs, univariate analysis identified 39 DE-lncRNAs with prognostic significance, and 9 DE-lncRNAs are included in ImmLnc database. Then, combined analysis was conducted, by integrating 9 immune related DE-lncRNAs, 369 immune related DE-mRNAs and 34 DE-miRNAs, and generated a ceRNA network composed of 2 upregulated lncRNAs (LINC01268 and CTB-31O20.2), 3 downregulated miRNAs and 5 upregulated mRNAs. Then we focused on LINC01268 and CTB-31O20.2, and Kaplan-Meier survival, univariate and multivariate Cox regression analysis showed that LINC01268 and CTB-31O20.2 serve as independent protective prognostic markers in GBM. Finally, LINC01268 and CTB-31O20.2 overexpression was conducted in GBM cell U251. CCK8, transwell and scratch healing assay indicated that LINC01268 and CTB-31O20.2 inhibits GBM cell line U251 proliferation, invasion and migration. To sum up, LINC01268 and CTB-31O20.2 are independent prognostic immune related markers, and reduces cancer cell proliferation and metastasis in GBM.

Abstract Objective Cardiovascular diseases (CVDs) are important complications for patients with rheumatoid arthritis (RA). The study aimed to explore whether serum leptin is associated with a increased risk of cardiovascular (CV) events in patients with RA. Methods Two hundred twenty-three patients with RA were followed for a mean of 40 (range = 8-42) months. Serum leptin levels were measured at baseline. Cox regression analysis was performed to assess the association between leptin levels and the risk of CV events. Results The univariate analysis showed that patients with RA with higher serum leptin levels had higher rates of CV events and CV mortality, respectively (P &lt;.001). The logistic regression model showed that leptin was independently related to CVD history (odds ratio = 1.603, 95% confidence interval [CI], 1.329–2.195; P =.005) after adjusting for confounding factors in patients with RA at baseline. The multivariate Cox proportional hazard model suggested that leptin was an independent prognostic factor for CV events in patients with RA after adjustments were made for clinical confounding factors (hazard ratio = 2.467, 95% CI, 2.019–4.495; P &lt;.001). The Kaplan-Meier analysis showed that compared with patients with RA with leptin levels below the median value (≤15.4 mg/L), patients with leptin above the median value (&gt;15.4 μg/L) had a higher rate of CV events (P &lt;.001). Conclusion Leptin was significantly associated with CV events in patients with RA. Elevated serum leptin levels may be a reliable prognostic factor for predicting CV complications in patients with RA.

109 Background: Neoadjuvant concurrent chemoradiotherapy (CCRT) is an effective treatment option for patients with rectal cancer. In this study, we investigated the clinical efficacy of simple endoscopic scoring of patients with rectal cancer after CCRT. Methods: Between July 2008 and October 2015, medical records including endoscopic imaging from 41 patients with rectal cancer who received CCRT were retrospectively reviewed. Two expert gastroenterologists reviewed the endoscopic images and assigned scores from 0–3 according to post-CCRT findings. The scoring criteria were as follows: 0 = scar without marginal elevation; 1 = clean-based ulcer without marginal elevation; 2 = clean-based ulcer with marginal elevation; 3 = non-clean-based ulcer. We evaluated image scores to predict long-term outcomes using Kaplan-Meier curves and Cox regression models. Results: The median follow-up duration was 55 months (interquartile range: 35–76). Patients with a low score (≤2) had a 17.2% recurrence rate, whereas patients with a high score (3) had a 50.0% recurrence rate. Patients with a low score had longer disease-free survival (DFS) than those with a high score in log-rank test (p = 0.026). In multivariate Cox regression analysis, a high score was a significant predictor of poor DFS in patients with rectal cancer after CCRT treatment (hazard ratio = 4.89, 95% confidence interval: 1.11–21.50, p = 0.036). Conclusions: This simple endoscopic scoring approach is helpful for predicting prognosis of patients with rectal cancer after treatment with CCRT.

Abstract Background Citric acid–based bicarbonate haemodialysis (CIT-HD) has gained more clinical acceptance over the last few years in France and is a substitute for other acidifiers [e.g. acetic acid (CH3COOH) and hydrochloric acid (HCl)]. This trend was justified by several clinical benefits compared with CH3COOH as well as the desire to avoid the consequences of the corrosive action of HCl, but a nationwide clinical report raised concerns about the long-term safety of CIT-HD. The aim of this study was to assess the long-term effects of CIT-HD exposure on patient outcomes in western France. Methods This is a population-based retrospective multicentre observational study performed in 1132 incident end-stage kidney disease patients in five sanitary territories in western France who started their renal replacement therapy after 1 January 2008 and followed up through 15 October 2018. Relevant data, collected prospectively with the same medical software, were anonymously aggregated for the purposes of the study. The primary goal of this study was to investigate the effects of citrate exposure on all-cause mortality. To provide a control group to CIT-HD one, propensity score matching (PSM) at 2:1 was performed in two steps: the first analysis was intended to be exploratory, comparing patients who received citrate ≤80% of the time (CIT-HD ≤80) versus those who received citrate &gt;80% of the time (CIT-HD &gt;80), while the second analysis was intended to be explanatory in comparing patients with 0% (CIT-HD0) versus 100% citrate time exposure (CIT-HD100). Results After PSM, in the exploratory part of the analysis, 432 CIT-HD ≤80 patients were compared with 216 CIT-HD &gt;80 patients and no difference was found for all-cause mortality using the Kaplan–Meier model (log-rank 0.97), univariate Cox regression analysis {hazard ratio [HR] 1.01 [95% confidence interval (CI) 0.71–1.40]} and multivariate Cox regression analysis [HR 1.11 (95% CI 0.76–1.61)] when adjusted for nine variables with clinical pertinence and high statistical relevance in the univariate analysis. In the explanatory part of the analysis, 316 CIT-HD0 patients were then compared with 158 CIT-HD100 patients and no difference was found using the Kaplan–Meier model (log-rank 0.06), univariate Cox regression analysis [HR 0.69 (95% CI 0.47–1.03)] and multivariate Cox regression analysis [HR 0.87 (95% CI 0.57–1.33)] when adjusted for seven variables with clinical pertinence and high statistical relevance in the univariate analysis. Conclusions Findings of this study support the notion that CIT-HD exposure ≤6 years has no significant effect on all-cause mortality in HD patients. This finding remains true for patients receiving high-volume online haemodiafiltration, a modality most frequently prescribed in this cohort.
