Objective: Our study aimed to evaluate the correlation of circular RNA SMARCA5 (circ-SMARCA5) and microRNA 432 (miR-432) with clinical characteristics and survival in bladder cancer patients. Methods: Preoperative clinicopathologic features and survival data of 156 bladder cancer patients were retrospectively reviewed. A total of 156 cases of tumor tissues, whereas 71 cases out of 156 available adjacent tissues were obtained from the Pathology Department for circ-SMARCA5 and miR-432 detections using real-time quantitative polymerase chain reaction. Results: Circ-SMARCA5 was upregulated but miR-432 was downregulated in tumor tissues compared with adjacent tissues; meanwhile, circ-SMARCA5 expression was negatively correlated with miR-432 in bladder cancer tissues. Circ-SMARCA5 high expression was correlated with larger tumor size, higher tumor stage, and lymph node (LYN) metastasis. However, miR-432 high expression was correlated with single multiplicity, smaller tumor size, lower tumor stage, less LYN metastasis in bladder cancer patients. Regarding survival, circ-SMARCA5 high expression was correlated with shorter disease-free survival (DFS) and overall survival (OS); whereas, miR-432 high expression was correlated with longer DFS and OS in bladder cancer patients. Further multivariate Cox's regression analysis displayed that circ-SMARCA5 high expression was an independent predictive factor for both worse DFS and OS in bladder cancer patients. Conclusion: Circ-SMARCA5 high expression but miR-432 low expression is correlated with advanced tumor features and poor survival of bladder cancer patients, which present as potential prognostic markers in bladder cancer.

Purpose. To compare the expression level of apelin in muscle-invasive bladder cancer and matched paracarcinoma tissues and investigate the relationship between apelin and clinical prognosis in the patients. Methods. To assess apelin expression by using immunohistochemical method compared with bladder tumors and matched paracarcinoma tissues. Subsequently, the correlation of apelin expression with the clinicopathological features of bladder cancer patients was analyzed. Kaplan-Meier survival curves method was used to analyze apelin prognostic significance for muscle-invasive bladder cancer patients (including 404 muscle-invasive bladder cancer patients and 28 normal bladder tissues, in TCGA dataset). Results. Apelin protein level was overexpressed in bladder tumor tissues compared with paracarcinoma tissues. Furthermore, high apelin expression was associated with high tumor stage (P<0.05), distant metastasis (P<0.05), and vascular invasion (P<0.05). Kaplan-Meier curve analyses showed that the overexpression of apelin was a potential predictor of overall survival and disease-free survival. Conclusion. Apelin was upregulated in bladder tumor tissues compared with matched adjacent noncancer tissues, especially in the high tumor stage, distant metastasis, and vascular invasion. What is more, high expression of apelin in muscle-invasive bladder cancer indicates the poor prognosis. These data suggested that apelin might be a therapeutic potential biomarker in muscle-invasive bladder cancer patients.

Background/Aims: This study aimed to validate the value of urothelial stem cell (USC) markers ΔNp63, integrin β4, CD47, and CD44v6 in predicting the prognosis of non-muscle invasive bladder cancer (NMIBC) located in different anatomic regions of bladder. Methods: The study reviewed the clinicopathologic data of 169 patients with NMIBC. Using real-time PCR and immunohistochemistry, the expression of ΔNp63, integrin β4, CD47, and CD44v6 in archived specimens of patients with NMIBC were validated. Kaplan–Meier analysis and Cox proportional hazards model were used to assess the prognostic impact of USC markers for recurrent-free survival (RFS). Results: The Real-time PCR data showed that the expression of USC markers were higher in tumors located in the trigone and posterior wall than that in other regions of bladder (P< 0.05). Statistical analysis showed that high expression of ΔNp63 was correlated with tumor stage (P=0.023) and tumor size (P=0.001), that high expression of integrin β4 was correlated with tumor stage (P=0.026), tumor grade (P=0.005) and tumor size (P=0.003), and that high integrin β4, CD47, and CD44v6 expression were significantly associated with tumor recurrence (P=0.032, P=0.010, and P=0.043, respectively). Moreover, high expression of ΔNp63 and integrin β4 was correlated with poor RFS in patients with tumors located in the trigone (P=0.025 and P=0.023, respectively). High expression of integrin β4, CD47, and CD44v6 was correlated with poor RFS in patients with tumors in the posterior wall (P=0.017, P=0.033 and P=0.047, respectively). High expression of integrin β4 and CD47 was correlated with poor RFS in patients with tumors in the trigone/posterior wall area (P=0.002 and P=0.005, respectively). Conclusion: Our results suggest that USC markers are linked with poor prognosis of NMIBC patients, especially in patients with tumors in the trigone and posterior wall.

AbstractThe spindle and kinetochore-associated protein complex (Ska) is an essential component in chromosome segregation. It comprises three proteins (Ska1, Ska2, and Ska3) with theorized roles in chromosomal instability and tumor development, and its overexpression has been widely reported in a variety of tumors. However, the prognostic significance and immune infiltration of Ska proteins in hepatocellular carcinoma (HCC) are not completely understood. The bioinformatics tools Oncomine, UALCAN, gene expression profiling interactive analysis 2 (GEPIA2), cBioPortal, GeneMANIA, Metascape, and TIMER were used to analyze differential expression, prognostic value, genetic alteration, and immune cell infiltration of the Ska protein complex in HCC patients. We found that the mRNA expression of the Ska complex was markedly upregulated in HCC. High expression of the Ska complex is closely correlated with tumor stage, patient race, tumor grade, and TP53 mutation status. In addition, high expression of the Ska complex was significantly correlated with poor disease-free survival, while the high expression levels of Ska1 and Ska3 were associated with shorter overall survival. The biological functions of the Ska complex in HCC primarily involve the amplification of signals from kinetochores, the mitotic spindle, and (via a MAD2 invasive signal) unattached kinetochores. Furthermore, the expression of the complex was positively correlated with tumor-infiltrating cells. These results may provide new insights into the development of immunotherapeutic targets and prognostic biomarkers for HCC.

The long noncoding RNA, Growth arrest-specific 5 (GAS5) plays a crucial role in the development of oral cancer. However, potential genetic variants in GAS5 that affect the susceptibility and progression of oral cancer have rarely been explored. In this study, two loci of GAS5 single nucleotide polymorphisms (SNPs) (rs145204276 and rs55829688) were genotyped by using the TaqMan allelic discrimination in 1125 oral cancer patients and 1195 non-oral-cancer individuals. After statistical analyses, the distribution of both the GAS5 SNP rs145204276 and GAS5 SNP rs55829688 frequencies were similar between the study and control groups. However, the patients with GAS5 SNP rs145204276 variants (Ins/Del or Del/Del) showed a higher tendency of moderate to poor cell differentiation of oral cancer (OR: 1.454, 95% CI: 1.041–2.031, p = 0.028). Moreover, the GAS5 SNP rs145204276 variants (Ins/Del or Del/Del) in the non-alcohol-drinking population were associated with significantly advanced tumor stage (OR: 1.500, 95% CI: 1.081–2.081, p = 0.015) and larger tumor size (OR: 1.494, 95% CI: 1.076–2.074, p = 0.016). Furthermore, individuals with the GAS5 SNP rs145204276 variant were associated with a higher expression of GAS5 in the GTEx database (p = 0.002), and the higher GAS5 level was associated with poor cell differentiation, advanced tumor stage and larger tumor size in head and neck squamous cell carcinoma from the TCGA database (all p < 0.05). In conclusion, the GAS5 SNP rs145204276 variant is related to poor-differentiation cell status in oral cancer. Besides, the presence of the GAS5 SNP rs145204276 variant is associated with a worse tumor stage and tumor size in oral cancer patients without alcohol drinking.

Abstract Background CKLF Like Marvel Transmembrane Domain Containing 1 (CMTM1) plays a role in breast cancer and lung cancer, but studies on the occurrence and development of CMTM1 in hepatocellular carcinoma (HCC) have not been reported. Methods The Cancer Genome Atlas (TCGA) database and immunohistochemistry (IHC) were used to detect CMTM1 expression in HCC tissues. The relationship between CMTM1 expression and the clinicopathological characteristics of HCC patients was analyzed by chi-square test, and the relationship between CMTM1 expression and the prognosis of HCC patients was tested by the Kaplan–Meier model. Results Bioinformatics analysis showed that the mRNA expression of CMTM1 was upregulated in HCC tissues, and low expression of CMTM1 is associated with longer disease-free survival in patients with HCC. Similarly, the survival time of HCC patients in CMTM1 high expression group was significantly shorter than that in CMTM1 low expression group. IHC detection indicated that CMTM1 protein was highly expressed in both HCC and adjacent non-tumor tissues, with a positive expression in 84% (63/75) of HCC tissues and 89.3% (67/75) of adjacent non-tumor tissues. Moreover, CMTM1 expression was related to family history and TNM stage of HCC patients (P < 0.05), but had no relationship with other clinicopathological characteristics. The survival analysis based on IHC results showed that the prognosis of HCC patients in CMTM1 negative group was significantly poorer than that in CMTM1 positive group (P < 0.05). Conclusion CMTM1 has a high expression in HCC tissues and is related to the prognosis of HCC patients.

In urogenital cancers, urine as a liquid biopsy for non-invasive cancer detection holds great promise for future clinical application. Their anatomical position allows for the local shedding of tumor DNA, but recent data indicate that tumor DNA in urine might also result from transrenal excretion. This study aims to assess the origin of tumor-associated DNA in the urine of 5 bladder and 25 cervical cancer patients. Besides natural voided urine, paired urine samples were collected in which contact with the local tumor was circumvented to bypass local shedding. The latter concerned nephrostomy urine in bladder cancer patients, and catheter urine in cervical cancer patients. Methylation levels of GHSR, SST, and ZIC1 were determined using paired bladder tumor tissues and cervical scrapes as a reference. Urinary methylation levels were compared to natural voided urine of matched controls. To support methylation results, mutation analysis was performed in urine and tissue samples of bladder cancer patients. Increased methylation levels were not only found in natural voided urine from bladder and cervical cancer patients, but also in the corresponding nephrostomy and catheter urine. DNA mutations detected in bladder tumor tissues were also detectable in all paired natural voided urine as well as in a subset of nephrostomy urine. These results provide the first evidence that the suitability of urine as a liquid biopsy for urogenital cancers relies both on the local shedding of tumor cells and cell fragments, as well as the transrenal excretion of tumor DNA into the urine.

Background We investigated whether all size-based pathological T4N0–N1 non-small cell lung cancer patients with tumors at any size >7 cm had the same outcomes. Methods We reviewed non-small cell lung cancer patients with tumors >7 cm who underwent anatomical lung resection between 2010 and 2016. A total of 251 size-based T4N0–N1 patients were divided into two groups based on tumor size. Group S ( n = 192) included patients with tumors of 7.1–9.9 cm and Group L ( n = 59) as tumor size ≥10 cm. Results The mean tumor size was 8.83 ± 1.7 cm (Group S: 8.06 ± 0.6 cm, Group L: 11.3 ± 1.6 cm). There were 146 patients with pathological N0 and 105 patients with pathological N1 disease. Mean overall survival and disease-free survival were 64.2 and 51.4 months, respectively. The five-year overall survival and disease-free survival rates were 51.2% and 43.5% (five-year OS; pT4N0:52.7%, pT4N1:47.9%, DFS; pT4N0:44.3%, pT4N1: 42.3%). No significant differences were observed between T4N0 and T4N1 patients in terms of five-year OS or DFS ( p = 0.325, p = 0.505 respectively). The five-year overall survival and disease-free survival rates were 52% and 44.6% in Group S, and 48.5% and 38.9% in Group L. No significant difference was observed between the groups in terms of five-year overall survival or disease-free survival ( p = 0.699, p = 0.608, respectively). Conclusions Above 7 cm, any further increase in tumor size in non-small cell lung cancer patients had no significant effect on survival, confirming it is not necessary to further discriminate among patients with tumors in that size class.

656 Background: There are emerging data showing prognostic significance of pre-treatment leukocytosis (elevated white blood cell count) in cervical cancer patients. However the prognostic impact of leukocytosis in anal cancer patients has not been previously reported. The purpose of this study was to determine the association of pre-treatment leukocytosis on outcome in patients with anal cancer treated with radical chemoradiotherapy (CRT) or radiotherapy (RT). Methods: 126 patients with anal cancer, treated with radical CRT (91.3%) or RT (8.7%) from 2 major Canadian cancer centers (University of Calgary, n=65 and University of Alberta, n=61), between 2000 and 2008 were evaluated. Demographic, clinical, hematologic and treatment factors were retrieved from retrospective review of the patients’ records. The association of clinical factors and hematologic status with overall survival (OS) and disease-free survival (DFS) was analyzed using Cox proportional hazards regression models. Results: Median follow-up was 24 months. Median tumor size was 4 cm. Mean age was 59 years and M:F was 29:97. Pre-treatment leukocytosis (WBC count greater than 10^9/L) was identified in 16% (20/126) of patients. After adjusting for gender, tumor size and stage in a multivariate analysis, leukocytosis remained significantly associated with worse 2-year OS [HR 2.9 (95% CI 1.1-7.9), p=0.036] and worse DFS [HR 2.2 (95% CI1.1-4.8), p=.045]. The patient group with both pre-treatment hemoglobin (Hgb) less than 125 g/L (lowest quartile) and leukocytosis had very poor outcomes, 2-year OS 61% versus 89% for patients without these factors; more than doubling the hazard for DFS [HR2.7 (95% CI 1.1-6.8), p=0.033] and for OS [4.5 (95% CI 1.5-13.2), p=.006]. Conclusions: Pre-treatment leukocytosis is associated with worse OS and DFS in patients with anal cancer treated with radical CRT or RT. Patients with both low Hgb and leukocytosis had very poor outcomes. These hematologic parameters represent potential biomarkers for prognosis and treatment response, and warrant further investigation to uncover the underlying biologic mechanisms and therapeutic strategies in this patient group.

e14688 Background: Thymidylate synthase (TS) plays an important role in colorectal carcinogenesis and response to 5FU-based chemotherapy. TS expression can be modified due to polymorphisms in the 5'-untranslated region (5’-UTR) of the gene. The aim of this study is to investigate the association between TS polymorphisms with clinicopathological characteristics of colon carcinomas. Methods: we retrospectively studied 89 individuals with high risk stage II (obstruction, T4 stage, presence of lymphovascular invasion or preoperative CEA > 5.0) and stage III patients submitted to curative intent surgery. DNA was extracted from paraffin embedded tumor tissues and sequenced. The polymorphism studied was the variation of the number of the repeated 28-bp sequences (3 or 2 repeats) of the TS gene 5’-UTR. Results: The frequency of the polymorphisms was: 2R2R in 26 cases (29.2%), 2R3R in 36 cases (40.4%), and 3R3R in 27 cases (30.3%). We did not find associations between the frequencies of these polymorphisms and age, gender, presence of lymphovascular invasion, or level of preoperative CEA. We find a significantly higher proportion of T4 tumors between the 3R3R genotype compared with the 2R2R and 2R3R genotypes (OR=2.69; 95% CI: 1.05 – 6.94; p=0.04). By the other hand, a significantly lower proportion of positive lymph nodes were found among patients with tumors presenting the 3R3R genotype, by comparing with the 2R2R and 2R3R subgroup (OR: 0.28; 95%CI: 0.10 – 0.72; p=0.01). Five-year disease free survival and overall survival were, respectively, 81% and 85% among patients with tumors presenting the 3R3R genotype, and 62% and 67% among patients with tumors presenting 2R2R or 2R3R genotypes. These differences were not statistically significant. Conclusions: in this sample, the TS polymorphic tumor genotype 3R3R was associated with lower risk of lymph node metastases in colon carcinomas.

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.
