Abstract Background Epithelial splicing regulatory protein 1 (ESRP1) and 2 (ESRP2) regulate alternative splicing events of various pre-mRNAs. Some of these targets play a role in cancer-associated processes, including cytoskeleton reorganization and DNA-repair processes. This study was undertaken to estimate the impact of ESRP1 and ESRP2 alterations on prostate cancer patient prognosis. Methods A tissue microarray made from 17,747 individual cancer samples with comprehensive, pathological, clinical and molecular data was analyzed by immunohistochemistry for ESRP1 and ESRP2. Results Nuclear staining for ESRP1 was seen in 38.6% (36.0% low, 2.6% high) of 12,140 interpretable cancers and in 41.9% (36.4% low, 5.3% high) of 12,962 interpretable cancers for ESRP2. Nuclear protein expression was linked to advanced tumor stage, high Gleason score, presence of lymph node metastasis, early biochemical recurrence, and ERG-positive cancers (p < 0.0001 each). Expression of ESRPs was significantly linked to 11 (ESRP1)/9 (ESRP2) of 11 analyzed deletions in all cancers and to 8 (ESRP1)/9 (ESRP2) of 11 deletions in ERG-negative cancers portending a link to genomic instability. Combined ESRPs expression analysis suggested an additive effect and showed the worst prognosis for cancers with high ESRP1 and ESRP2 expression. Multivariate analyses revealed that the prognostic impact of ESRP1, ESRP2 and combined ESRP1/ESRP2 expression was independent of all established pre- and postoperative prognostic features. Conclusions Our data show a striking link between nuclear ESRP expression and adverse features in prostate cancer and identifies expression of ESRP1 and/or ESRP2 as independent prognostic markers with a potential for routine application.

Radical prostatectomy (RP) is a curatively intended treatment option for clinically localized non-metastatic prostate cancer (PCa). Novel biomarkers could refine treatment choice based on a better identification of men at risk of biochemical recurrence (BCR) following therapy. The urokinase plasminogen activator receptor (uPAR) system is a promising biomarker of aggressiveness in many cancers. The predictive value of uPAR after curatively intended treatment for PCa remains to be elucidated. This was a prospective evaluation of uPAR analysis in men with prostate cancer (Copenhagen uPAR prostate cancer (CuPCA) database). Risk of BCR following RP was analyzed using cumulative incidences with competing risk and tested with Gray’s test. Associations between quartile groups of uPAR levels and BCR were assessed with uni- and multivariate Cox proportional hazards. In total, 532 men were included. With more advanced tumor stage, Gleason score (GS), and prostate-specific antigen (PSA) the uPAR I–III + II–III plasma levels increased. Quartile levels of plasma uPAR I–III, I–III + II–III showed no significant association between the risk of BCR and the plasma uPAR levels in uni- and multivariate analysis. Despite increased levels of uPAR I–III + II–III in advanced tumor stage, intact and cleaved uPAR levels were not associated with BCR and are not predictive biomarkers for BCR following curatively intended treatment of PCa. It is unlikely that further studies of uPAR in RP treated patients is needed.

37 Background: Chromosomal deletions are frequent in prostate cancer (PCa) but target genes and potential clinical significance are often unknown. This project aimed at the identification of frequent and new deletions in PCa and to study their association with tumor phenotype and PSA recurrence. Methods: Array CGH was performed on 77 advanced PCa. Deletions of interest were subsequently analyzed on a tissue microarray containing more than 2000 PCa with clinical follow-up data using fluorescence in situ hybridization (FISH). The FISH probes used included a break-apart probe for TMPRSS2-ERG and dual-labeling probes for centromere 10/PTEN and centromere 3/3p14. Results: The most frequent circumscribed deletions found by array CGH were 3p14 (including FOXP1) in 18%, 5q31 in 16%, 5q21 in 14%, 6q13 in 21%, 6q21 in 19%, 6q26 in 14%, 8p11 in 17%, 10q23 (including PTEN) in 18%, 12p13 in 14%, 13q14 in 14%, 16q24 in 22% and 21q (representing TMPRSS2-ERG fusion) in 18%. TMPRSS2-ERG fusions, PTEN and FOXP1 deletions were selected for FISH analysis. A TMPRSS2-ERG fusion was observed in 394 of 947 interpretable cases (41.6%). TMPRSS2-ERG fusion was unrelated to tumor stage, Gleason grade, and PSA recurrence. PTEN deletions were observed in 8.9% of 1844 interpretable cases and were associated with advanced tumor stage (p<0.0001), high Gleason grade (p<0.0001), and early biochemical recurrence (p<0.0001). FOXP1 deletions were seen in 5.0% of 619 cases. FOXP1 deletions were not significantly linked to tumor phenotype and outcome. Both PTEN and FOXP1 deletions were strongly linked to TMPRSS2-ERG fusions. TMPRSS2-ERG fusion positive tumors had PTEN deletions in 15.4% and FOXP1 deletions in 10.7%, while TMPRSS2-ERG fusion negative cancers had PTEN deletions in only 5.8% and FOXP1 deletions in only 2.0% of cases (p<0.0001 each). Conclusions: The TMPRSS2-ERG fusion determines a genetically distinct subgroup of prostate cancers. Our data provide no evidence for a particular clinical behaviour of TMPRSS2-ERG fusion positive cancers in radically operated patients. PTEN and FOXP1 alterations are preferentially found in TMPRSS2-ERG fusion positive cancers. Both genes may potentially be involved in pathway dysregulation in these cancers. No significant financial relationships to disclose.

Purpose To evaluate cytoplasmic and nuclear ErbB-4 expression in prostate cancer specimens and its association with outcome. Basic procedures Specimens of 50 prostate cancer patients were investigated for ErbB-4 overexpression using immunohistochemistry staining. Cytoplasmic and nuclear staining was graded as 0–3 according to its intensity. The prognostic parameters were tumor stage, PSA level, Gleason score, probability of positive lymph nodes (Partin's tables and Roach equation), and 5-year disease free survival (Kattan nomogram). Main findings Overexpression of ErbB-4 (≥1) was detected in 30 (60%) patients and overexpression using cytoplasmic and nuclear staining was ≥2 in 19 (38%) and 17 (34%) patients, respectively. In only one third of the specimens was there any similarity between the 2 types of staining. Advanced tumor stage, high pretreatment PSA levels and high Gleason scores were evenly distributed among the patients with low (≤1) and intermediate/high (≥2) ErbB-4 expression. The probability of lymph node involvement and 5-year disease free survival were similar in both types of staining. Principal conclusions ErbB-4 was overexpressed (cytoplasmic and nuclear staining) in approximately one third of prostate cancer patients. The rate of similarity between the 2 staining types was only 33%: overexpression was evenly distributed among intermediate/high and low risk prostate cancer patients with both staining methods.

124 Background: We have previously shown that nuclear accumulation of p53 is rare in prostate cancer but strongly linked to early biochemical recurrence (Schlomm et al., Modern Pathology, 2008). The current study was designed to study the association between ERG fusion and p53 in a large series of prostate cancers. Methods: A prostate cancer tissue microarray (TMA) was constructed from 4,699 radical prostatectomie specimens with histological, pathological, and clinical follow-up data. Immunohistochemistry was applied to detect nuclear p53 accumulation as a marker for defective p53 and to detect ERG expression as a surrogate for ERG gene fusion. Results: Nuclear accumulation of p53 was detected in 62/3,667 (1.7%) analyzable tissue spots. Positive staining was significantly linked to advanced tumor stage (p<0.0001), high Gleason score (p<0.0001), presence of lymph node metastases (p=0.0005), and early PSA recurrence (p<0.0001) in all cancers. ERG expression was found in 1,990/4,266 (46.6%) analyzable cancers, but was unrelated to tumor phenotype or patient prognosis. Results of both p53 and ERG were available from 3,392 tumors. Presence of nuclear p53 staining was linked to ERG fusion positive cancers: 40 (2.7%) of 1,491 ERG-positive cancers, but only 20 (1.1%) of 1,901 ERG-negative tumors showed nuclear p53 staining (p=0.0004). A Kaplan-Meier survival analysis of p53 in the subsets of 1,699 ERG positive and 1,280 ERG negative cancers revealed that nuclear p53 accumulation was strongly linked to early PSA recurrence in both subsets (p<0.0001 each). Conclusions: These data demonstrate that the poor prognosis of prostate cancer patients with nuclear p53 accumulation is independently from the ERG fusion status, but suggest a distinct biological role of p53 inactivation in ERG fusion positive cancers. The very high number of prostate cancer samples included in the TMA used in this study allows for analysis of rare events such as p53 alterations with high statistical power.

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.

AbstractBackgroundBladder cancer (BLCA) is a malignant urothelial carcinoma and has a high mortality rate. EPDR1 (ependymin related 1) is a type II transmembrane protein and related to calcium-dependent cell adhesion.MethodsWe explored the potential oncogenic roles of EPDR1 in BLCA basing on the multiple public datasets.ResultsWe found that EPDR1 expression had a significant difference in BLCA and adjacent normal bladder tissues, and the level of EPDR1was up-regulated with advanced tumor stage and metastasis in BLCA. Meanwhile, the high expression group of EPDR1 had a shorter OS compared to the low or medium expression-group. Furthermore, EPDR1 expression was associated with tumor-infiltrating immune cells (TIICs), including NK cells, CD8 + T cells, CD4 + T cells, Macrophages cells, and so on. Moreover, EPDR1 also involved in several signaling pathways as well as PI3K/AKT pathway, Cytokine receptor interaction, and apoptosis.ConclusionEPDR1 can be used as a novel prognostic biomarker as well as an effective target for diagnosis and treatment in BLCA.
