Abstract
A 28-year-old male with bilateral testicular seminoma underwent bilateral orchiectomy and radiation therapy of the retroperitoneum. After 17 years, he had a retroperitoneal tumor detected, which was removed 7 years later at age 52 because of its progressive enlargement. Due to its partially cystic and partially solid structure, the radiologic findings could not exclude the possibility of regressively altered seminoma metastasis. After radical surgical removal of the tumor, the histopathological and immunohistochemical examination of the tumor revealed ancient schwannoma. These tumors, although unusual, might pose a clinical diagnostic challenge with the risk of undesired overtreatment.

Abstract
Germ cell tumors (GCTs) usually represent efficiently curable neoplasms due to their chemosensitivity to platinum-based therapeutic regimen. However, some patients develop therapeutic resistance and succumb to their disease. Novel therapeutic approaches are therefore needed for these patients. It has previously been demonstrated that poly (ADP-ribose) polymerase (PARP) expression is upregulated in GCTs compared with normal testis tissue. Therefore, PARP expression was analyzed in GCT cell lines and xenografts and it was examined whether its inhibition by veliparib can reverse cisplatin-resistance. Its expression was analyzed in sensitive and cisplatin-resistant variants (referred to as CisR throughout the manuscript) GCT cell lines and xenografts using quantitative PCR, western blotting and immunohistochemistry. The present study investigated whether the combination of cisplatin with the PARP inhibitor veliparib increased the cytotoxic effect of cisplatin in vitro using a luminescent viability assay and an immunodeficient mouse model in vivo. PARP expression was observed in all tested cell lines, with the highest expression in embryonal carcinoma (EC) cell lines and xenografts. Low or no expression was detected in the JEG-3 choriocarcinoma cell line pairs and xenografts. The combination of veliparib and cisplatin or carboplatin was examined in the cisplatin-resistant NTERA-2 CisR and NCCIT CisR EC cell lines and synergistic effects were observed in NTERA-2 CisR cells. However, in vivo analysis did not confirm this synergy. The present data indicated PARP expression in GCT cell lines and xenografts. However, veliparib failed to increase the cytotoxicity of platinum-based drugs. Therefore, further research is warranted to effectively inhibit PARP using different PARP inhibitors or other drug combinations.

Abstract
Background Circulating tumor cells (CTCs) contribute to the metastatic cascade and represent an independent survival predictor in breast cancer (BC) patients. Vitamin D has pleiotropic effects, and its low concentrations are associated with breast cancer and metastasis. The aim of this study was to assess plasma vitamin D in primary BC patients in relation to CTCs. Methods This study included 91 non-metastatic BC patients (stage I–III) and 24 healthy donors. Blood samples for the analyses were drawn at the time of surgery. CTCs were assessed using a quantitative RT-PCR assay for expression of epithelial (CK19) or epithelial-to-mesenchymal transition (EMT) genes (TWIST1, SNAIL1, SLUG, and ZEB1). Total 25-OH vitamin D was measured in plasma using ELISA. Plasma cytokines and angiogenic factors were measured by enzyme-linked immunoassay. Results CTCs were detected in 30 (33%) patients. Patients with detectable CTCs in peripheral blood had significantly lower vitamin D concentrations in comparison to patients without detectable CTCs ((mean ± SD) 8.50 ± 3.89 µg/L for CTC-positive vs 9.69 ± 3.49 µg/L for CTC-negative patients, p = 0.03). The mean ( ± SD) vitamin D plasma level was 9.3 ± 3.65 µg/L for breast cancer patients compared to 18.6 ± 6.8 for healthy donors (p < 0.000001). There was no association between plasma vitamin D and other patient/tumor characteristics. Plasma vitamin D levels are inversely correlated with plasma TGF-β1, TGF-β2, IL β, IL-5, and eotaxin (all p < 0.05). Patients with vitamin D above the median had a better overall survival (hazard ratio (HR) = 0.36, 95% CI 0.16–0.80, p = 0.017), and combined analysis showed the best survival for CTC-negative patients with vitamin D levels above the median as compared to patients with opposite characteristics (HR = 0.18, 95% CI 0.05–0.63, p = 0.004). Conclusions Low vitamin D could be a consequence and hence a biomarker of a more invasive disease. Alternatively, vitamin D could be associated with survival because of its role in tumor dissemination. Whether its supplementation affects the metastatic cascade should be tested in animal experiments and interventional studies.

Abstract
Abstract
Background: Matrix metalloproteinase 9 (MMP9) is involved in the extracellular matrix degradation during physiological and pathological conditions including tumorigenesis. This translational study was aimed to evaluate the prognostic role of the intratumoral MMP9 expression and correlate it with presence of CTCs in early breast cancer. Methods: A total of 318 primary breast cancer (PBC) patients were enrolled into this study. Surgical specimens were processed by the tissue microarray method and subjected to immunohistochemistry using the MMP9 monoclonal antibody. The MMP9 expression was evaluated in tumor cell as well as in tumor associated stroma. Quantitative real-time polymerase chain reaction -based assays was applied for identification of CTCs. Results: Significantly increased expression of MMP9 was found in breast cancer cells when compared to tumor associated stroma. A positive correlation was determined between MMP9 expression and hormone positive status as well as low proliferation index of analysed breast cancer tumour cells. Additionally, in tumor associated stroma was confirmed only the association with hormone receptor status. The univariate survival analysis of whole tested population detected no prognostic role of MMP9 expression neither in tumor cells (HR = 0.96, 95% CI 0.58-1.59, P = 0.864) nor in tumor associated stroma (HR = 1.29, 95% CI 0.60-2.78, P = 0.547). However, the subgroup of in hormone receptor negative and triple negative patients with absence of MMP9 expression in tumor cells and stroma had significantly better disease-free survival (DFS) (HR = 0.33, 95% CI 0.12-0.93, P = 0.025, and (HR = 0.14, 95% CI 0.00-4.81, P = 0.002, respectively) and (HR = 0.17, 95% CI 0.05-0.57, P = 0.003); (HR = 0.12, 95% CI 0.00-4.89, P = 0.001) compared with patients with presence of MMP9. Moreover, while tumor MMP9 was prognostic in CTC_EMT positive subgroup (HR = 0.40, 95% CI 0.16-0.95, P = 0.047), absence of stromal MMP9 had protective role in CTC_EP positive patients (HR = 0.18, 95% CI 0.01-2.75, P = 0.053). Conclusions: Our data suggest that the increased expression of MMP9 in PBC was related with favorable tumor characteristics. However, it´s prognostic value was limited only to hormone receptor negative, triple negative, CTC_EMT and CTC_EP positive subgroups. Therefore, we can suppose that evaluating of MMP9 tumor expression could help identify patients with increased risk of disease recurrence in these subgroups of patients.

Abstract
Simple Summary Germ cell tumors (GCTs) are the most common solid malignancies in young men. GCTs are extraordinary sensitive to chemotherapy and represent a model of curable cancer. However, in a small proportion of patients the disease progresses or relapses despite administration of salvage chemotherapy. Apoptosis is a form of programmed cell death that occurs in multicellular organisms. It is well established that dysregulation of apoptosis plays an important role in pathogenesis of malignant diseases and may be associated with tumor progression and resistance to cytotoxic treatment. This study aimed to evaluate expression of apoptosis inducing factor (AIF) in GCTs. We observed lower AIF expression in GCTs compared to normal testicular tissue. We also showed prognostic significance of AIF in GCTs. AIF downregulation might represent one of the mechanisms of inhibition of apoptosis with subsequent facilitation of cell survival and metastatic dissemination of GCTs and perhaps could serve as a potential therapeutic target. Abstract Apoptosis is a strictly regulated process essential for preservation of tissue homeostasis. This study aimed to evaluate expression of apoptosis inducing factor (AIF) in testicular germ cell tumors (GCTs) and to correlate expression patterns with clinicopathological variables. Formalin-fixed and paraffin-embedded specimens of non-neoplastic testicular tissue and GCTs obtained from 216 patients were included in the study. AIF expression was detected by immunohistochemistry, scored by the multiplicative quickscore method (QS). Normal testicular tissue exhibits higher cytoplasmic granular expression of AIF compared to GCTs (mean QS = 12.77 vs. 4.80, p < 0.0001). Among invasive GCTs, mean QS was the highest in embryonal carcinoma, yolk sac tumor and seminoma, lower in teratoma and the lowest in choriocarcinoma. No nuclear translocation of AIF was observed. Nonpulmonary visceral metastases were associated with lower AIF expression. Metastatic GCTs patients with high AIF expression had better overall survival compared to patients with low AIF expression (HR = 0.26, 95% CI 0.11–0.62, p = 0.048). We observed significantly lower AIF expression in GCTs compared to normal testicular tissue, which is an uncommon finding in malignant tumors. AIF downregulation might represent one of the mechanisms of inhibition of apoptosis and promotion of cell survival in GCTs.

Abstract
Circulating tumor cells (CTCs) and the immune infiltration of tumors are closely related to clinical outcomes. This study aimed to verify the influence of stromal lymphocyte infiltration and the immune context of tumor microenvironment on the hematogenous spread and prognosis of 282 chemotherapy naïve primary BC patients. To detect the presence of mesenchymal CTCs, RNA extracted from CD45-depleted peripheral blood was interrogated for the expression of mesenchymal gene transcripts. Tumor-infiltrating lymphocytes (TILs) were detected in the stromal areas by immunohistochemistry, using CD3, CD8, and CD45RO antibodies. The concentrations of 51 plasma cytokines were measured by multiplex bead arrays. TILs infiltration in mesenchymal CTC-positive patients significantly decreased their progression-free survival (HR = 4.88, 95% CI 2.30–10.37, p < 0.001 for CD3high; HR = 6.17, 95% CI 2.75–13.80, p < 0.001 for CD8high; HR = 6.93, 95% CI 2.86–16.81, p < 0.001 for CD45ROhigh). Moreover, the combination of elevated plasma concentrations of transforming growth factor beta-3 (cut-off 662 pg/mL), decreased monocyte chemotactic protein-3 (cut-off 52.5 pg/mL) and interleukin-15 (cut-off 17.1 pg/mL) significantly increased the risk of disease recurrence (HR = 4.838, 95% CI 2.048–11.427, p < 0.001). Our results suggest a strong impact of the immune tumor microenvironment on BC progression, especially through influencing the dissemination and survival of more aggressive, mesenchymal CTC subtypes.

MMP9 is involved in extracellular matrix degradation during various physiological and pathological conditions, including tumorigenesis. The present study aimed to assess the prognostic role of intratumoral MMP9 and to determine its association with circulating tumor cells (CTCs) in patients with early breast cancer. A total of 318 patients with primary breast cancer (PBC) were enrolled into the present study. Specimens were subjected to immunohistochemistry analysis, using the MMP9 monoclonal antibody. MMP9 expression was scored using a weighted histoscore (WH). The results demonstrated that the mean WH ± SEM for MMP9 expression was significantly higher in breast tumor cells compared with tumor associated stromas (132.0±5.2 vs. 50.8±3.7; P<0.00001). Furthermore, a positive association was observed between MMP9 expression, the hormone positive status and proliferation index of analysed breast cancer tumour cells. Notably, the prognostic role of MMP9 was not observed in tumor cells [hazard ratio (HR) =0.96; 95% confidence interval (CI), 0.58-1.59; P=0.864] or tumor associated stroma (HR=1.29; 95% CI, 0.60-2.78; P=0.547). Subgroup analysis demonstrated that patients that were HR negative or triple negative, with low MMP9 expression in tumor cells and stroma had a significantly improved disease-free survival than patients with high MMP9 expression. Taken together, the results of the present study demonstrated that high MMP9 expression in PBC was associated with favorable tumor characteristics. However, the prognostic value of MMP9 was limited to only the HR negative and CTC epithelial-to-mesenchymal transition positive subgroups. Thus, analyzing MMP9 tumor expression may help identify patients with increased risk of disease recurrence in these subgroups.

Abstract
Abstract
Background: Circulating tumor cells (CTCs) play role in tumor dissemination and are an independent survival predictor in breast cancer (BC) patients. PD-L1 is prognostic factor in BC and PD-L1 inhibitors prolonged survival in metastatic triple-negative breast cancer. The aim of this study was to assess correlation between CTCs and tumor PD-L1 in BC. Methods: This study included 299 primary BC patients treated by surgery from March 2012 to February 2015. Peripheral blood mononuclear cells (PBMC) were depleted of hematopoietic cells using RossetteSepTM negative selection kit. RNA extracted from CD45-depleted PBMC was interrogated for expression of EMT (TWIST1, SNAIL1, SLUG, ZEB1) and epithelial (CK19) gene transcripts by qRT-PCR. Patient samples with higher epithelial and/or mesenchymal gene transcripts than those of healthy donors (n=60) were considered as CTC positive. Expression of PD-L1 in surgical specimens was evaluated by immunohistochemistry and quantified by multiplicative score (proportion of cells with staining x intensity of staining). Results: CTCs were detected in 75 (25.1%) of patients. CTCs exhibiting only epithelial markers were present in 28 (9.4%) of patients, whereas CTCs with only EMT markers were observed in 53 (17.7%) of patients. In 6 patients, CTCs exhibit both epithelial and EMT markers. Patients with EMT_CTCs had significantly higher mean ± SEM score of PD-L1 expression in tumor associated stroma than those of patients without EMT_CTCs (2.66 ± 0.62 vs. 0.88 ± 0.29, p=0.048). There was no association between CTCs and PD-L1 expression in cancer cells including CTCs subtypes. Tumors without PD-L1 expression had significantly better disease-free survival compared to patients with PD-L1 expression (HR = 0.50, 95%CI 0.29 - 0.86, P = 0.001), however, this prognostic value was restricted to CTC positive subpopulation (HR = 0.24, 95%CI 0.10 - 0.56, P = 0.002), while, in CTC negative patients PD-L1 lack prognostic value (HR = 0.77, 95%CI 0.39 - 1.54, P = 0.45) Conclusion: Our data suggest link between PD-L1 expression in tumor associated stroma and CTCs with EMT phenotype and thus further support connection between immunosuppression and EMT. PD-L1 expression is prognostic only in patients with detectable CTC in peripheral blood suggesting different biology of tumors with detectable CTCs.

Abstract
Background Germ cell tumours (GCTs) represent a highly curable malignity as they respond well to cisplatin (CDDP)-based chemotherapy. Nevertheless, a small proportion of GCT patients relapse or do not respond to therapy. As this might be caused by an increased capacity to repair CDDP-induced DNA damage, identification of DNA repair biomarkers predicting inadequate or aberrant response to CDDP, and thus poor prognosis for GCT patients, poses a challenge. The objective of this study is to examine the expression levels of the key nucleotide excision repair (NER) factors, XPA, ERCC1 and XPF, in GCT patients and cell lines. Methods Two hundred seven GCT patients’ specimens with sufficient follow-up clinical-pathological data and pairwise combinations of CDDP-resistant and -sensitive GCT cell lines were included. Immunohistochemistry was used to detect the ERCC1, XPF and XPA protein expression levels in GCT patients’ specimen and Western blot and qRT-PCR examined the protein and mRNA expression levels in GCT cell lines. Results GCT patients with low XPA expression had significantly better overall survival than patients with high expression (hazard ratio = 0.38, 95% confidence interval: 0.12–1.23, p = 0.0228). In addition, XPA expression was increased in the non-seminomatous histological subtype, IGCCCG poor prognosis group, increasing S stage, as well as the presence of lung, liver and non-pulmonary visceral metastases. Importantly, a correlation between inadequate or aberrant CDDP response and XPA expression found in GCT patients was also seen in GCT cell lines. Conclusions XPA expression is an additional independent prognostic biomarker for stratifying GCT patients, allowing for improvements in decision-making on treatment for those at high risk of refractoriness or relapse. In addition, it could represent a novel therapeutic target in GCTs.

Abstract
Cisplatin resistance in testicular germ cell tumors (TGCTs) is a clinical challenge. We investigated the underlying mechanisms associated with cancer stem cell (CSC) markers and modalities circumventing the chemoresistance. Chemoresistant models (designated as CisR) of human embryonal carcinoma cell lines NTERA-2 and NCCIT were derived and characterized using flow cytometry, gene expression, functional and protein arrays. Tumorigenicity was determined on immunodeficient mouse model. Disulfiram was used to examine chemosensitization of resistant cells. ALDH1A3 isoform expression was evaluated by immunohistochemistry in 216 patients' tissue samples. Chemoresistant cells were significantly more resistant to cisplatin, carboplatin and oxaliplatin compared to parental cells. NTERA-2 CisR cells exhibited altered morphology and increased tumorigenicity. High ALDH1A3 expression and increased ALDH activity were detected in both refractory cell lines. Disulfiram in combination with cisplatin showed synergy for NTERA-2 CisR and NCCIT CisR cells and inhibited growth of NTERA-2 CisR xenografts. Significantly higher ALDH1A3 expression was detected in TGCTs patients' tissue samples compared to normal testicular tissue. We characterized novel clinically relevant model of chemoresistant TGCTs, for the first time identified the ALDH1A3 as a therapeutic target in TGCTs and more importantly, showed that disulfiram represents a viable treatment option for refractory TGCTs.

Abstract
OBJECTIVES To analyze a rare triad of intracranial fetal pathologies and clinical study of the novel defined sequence pathogenesis based on prenatal and postmortem findings. METHODS Complex multidisciplinary clinical analysis and review of up-to-date literature. RESULTS In an 18-gestational-week fetus the screening ultrasound scan resembled the semilobar type of holoprosencephaly and oral tumor. After the indicated termination of pregnancy, the histopathology results confirmed another pathologies - oral meningoencephalocele, teratoma of the sellar area and large arachnoidal cyst of the anterior cerebral fossa. The surprising final results were evaluated by specialists in prenatal diagnosis, histopathology, genetics, neurology, and radiology. CONCLUSION We defined the final diagnosed triad oral meningoencephalocele - intracranial sellar teratoma- arachnoidal cyst as a novel sequence defect malformation. In the detailed sequence pathogenesis, the intracranial sellar teratoma created an aperture for meningoencephalocele in the cranial base and the arachnoidal cyst facilitated, by its growth and pressure, the protrusion of the brain tissues (Fig. 4, Ref. 10).

Abstract
A Disintegrin And Metalloprotease 23 (ADAM23), a member of the ADAM family, is involved in neuronal differentiation and cancer. ADAM23 is considered a possible tumor suppressor gene and is frequently downregulated in various types of malignancies. Its epigenetic silencing through promoter hypermethylation was observed in breast cancer (BC). In the present study, we evaluated the prognostic significance of ADAM23 promoter methylation for hematogenous spread and disease-free survival (DFS). Pyrosequencing was used to quantify ADAM23 methylation in tumors of 203 BC patients. Presence of circulating tumor cells (CTC) in their peripheral blood was detected by quantitative RT-PCR. Expression of epithelial (KRT19) or mesenchymal (epithelial-mesenchymal transition [EMT]-inducing transcription factors TWIST1, SNAI1, SLUG and ZEB1) mRNA transcripts was examined in CD45-depleted peripheral blood mononuclear cells. ADAM23 methylation was significantly lower in tumors of patients with the mesenchymal CTC (P = .006). It positively correlated with Ki-67 proliferation, especially in mesenchymal CTC-negative patients (P = .001). In low-risk patients, characterized by low Ki-67 and mesenchymal CTC absence, ADAM23 hypermethylation was an independent predictor of DFS (P = .006). Our results indicate that ADAM23 is likely involved in BC progression and dissemination of mesenchymal CTC. ADAM23 methylation has the potential to function as a novel prognostic marker and therapeutic target.

Abstract
AIM The purpose of this study was to monitor the association between single umbilical artery (SUA), chromosomal abnormalities and associated anomalies during the routine examination of spontaneous or induced miscarriages and premature births. METHODS During 1992-2015 we morphologically and cytogenetically examined a series of 4098 samples. For 1330 cases the number of umbilical cord vessels could be reported. RESULTS The presence of single umbilical artery was identified in 67 fetuses of 1330 pregnancies (5.04 %); 36 of the 67 fetuses (53.7 %) had additional congenital malformations. The cultures were unsuccessful in 29 of 67 cases (43.3 %). 38 cases (56.7 %) were successfully karyotyped; 20 out of them had a normal karyotype and 18 had chromosomal anomalies including trisomy 18 (n = 4), trisomy 13 (n = 3), trisomy 21 (n = 2), trisomy 11 (n = 1), triploidy (n = 3), monosomy X (n = 3) and structural chromosomal aberrations (n = 2). CONCLUSION Isolated SUA is not at increased risk of chromosomal abnormalities and generally does not endanger pregnancy. All chromosomally abnormal embryos and fetuses had associated congenital anomalies. The most frequently associated congenital anomalies were in the musculoskeletal system, central nervous system and genitourinary tract (Tab. 4, Ref. 44).

Abstract
BACKGROUND WNT/βcatenin (WNTβ) pathway is activated in early stages of embryonic development. We aimed to evaluate the significance of βcatenin in germ cell tumors (GCTs) and explore associations with the inflamed environment. METHODS Surgical specimens from 247 patients were analyzed. Βcatenin expression was detected in the tumor tissue by immunohistochemistry and correlated with clinical characteristics, outcome, PD-L1 expression and systemic immune-inflammation index (SII). The Ingenuity Pathway Analysis (IPA) was used to investigate the immune-cell related effects of βcatenin and PD-L1 encoding genes. RESULTS βcatenin was expressed in 86.2% of GCTs. The expression in seminomas was significantly lower compared to all subtypes of non-seminoma (all P < 0.0001). A high expression (weighted histoscore > 150) was associated with primary mediastinal non-seminoma (P = 0.035), intermediate/poor risk disease (P = 0.033) and high tumor markers (P = 0.035). We observed a positive correlation with the PD-L1 in tumor and an inverse correlation with the SII. IPA uncovered relationships of CTNNB (βcatenin) and CD274 (PD-L1) genes and their effects on differentiation, proliferation and activation of lymphocyte subtypes. CONCLUSION Herein, we showed that βcatenin is associated with male adult GCT characteristics as well as supressed immune environment.

Abstract
BACKGROUND In breast cancer (BC), deregulation of DNA methylation leads to aberrant expressions and functions of key regulatory genes. In our study, we investigated the relationship between the methylation profiles of genes associated with cancer invasivity and clinico-pathological parameters. In detail, we studied differences in the methylation levels between BC patients with haematogenous and lymphogenous cancer dissemination. METHODS We analysed samples of primary tumours (PTs), lymph node metastases (LNMs) and peripheral blood cells (PBCs) from 59 patients with sporadic disseminated BC. Evaluation of the DNA methylation levels of six genes related to invasivity, ADAM23, uPA, CXCL12, TWIST1, SNAI1 and SNAI2, was performed by pyrosequencing. RESULTS Among the cancer-specific methylated genes, we found lower methylation levels of the SNAI2 gene in histologic grade 3 tumours (OR = 0.61; 95% CI, 0.39-0.97; P = 0.038) than in fully or moderately differentiated cancers. We also evaluated the methylation profiles in patients with different cancer cell dissemination statuses (positivity for circulating tumour cells (CTCs) and/or LNMs). We detected the significant association between reduced DNA methylation of ADAM23 in PTs and presence of CTCs in the peripheral blood of patients (OR = 0.45; 95% CI, 0.23-0.90; P = 0.023). CONCLUSION The relationships between the decreased methylation levels of the SNAI2 and ADAM23 genes and cancer de-differentiation and haematogenous dissemination, respectively, indicate novel functions of those genes in the invasive processes. After experimental validation of the association between the lower values of SNAI2 and ADAM23 methylation and clinical features of aggressive BCs, these methylation profiles could improve the management of metastatic disease.

Abstract
Background Efficiency of colorectal carcinoma treatment by chemotherapy is diminished as the resistance develops over time in patients. The same holds true for 5-fluorouracil, the drug used in first line chemotherapy of colorectal carcinoma. Methods Chemoresistant derivative of HT-29 cells was prepared by long-term culturing in increasing concentration of 5-fluorouracil. Cells were characterized by viability assays, flow cytometry, gene expression arrays and kinetic imaging. Immunomagnetic separation was used for isolation of subpopulations positive for cancer stem cells-related surface markers. Aldehyde dehydrogenase expression was attenuated by siRNA. In vivo studies were performed on SCID/bg mice. Results The prepared chemoresistant cell line labeled as HT-29/EGFP/FUR is assigned with different morphology, decreased proliferation rate and 135-fold increased IC50 value for 5-fluorouracil in comparison to parental counterparts HT-29/EGFP. The capability of chemoresistant cells to form tumor xenografts, when injected subcutaneously into SCID/bg mice, was strongly compromised, however, they formed distant metastases in mouse lungs spontaneously. Derived cells preserved their resistance in vitro and in vivo even without the 5-fluorouracil selection pressure. More importantly, they were resistant to cisplatin, oxaliplatin and cyclophosphamide exhibiting high cross-resistance along with alterations in expression of cancer-stem cell markers such as CD133, CD166, CD24, CD26, CXCR4, CD271 and CD274. We also detected increased aldehyde dehydrogenase (ALDH) activity associated with overexpression of specific ALDH isoform 1A3. Its inhibition by siRNA approach partially sensitized cells to various agents, thus linking for the first time the ALDH1A3 and chemoresistance in colorectal cancer. Conclusion Our study demonstrated that acquired chemoresistance goes along with metastatic and migratory phenotype and can be accompanied with increased activity of aldehyde dehydrogenase. We describe here the valuable model to study molecular link between resistance to chemotherapy and metastatic dissemination.

Abstract
Background: We evaluated systemic immune-inflammation index (SII) and its association with patient outcome in germ-cell tumours (GCTs). Methods: Two independent cohorts of patients were analysed; the discovery set (n=171) from a single institution and the validation set (n=181) previously included in a study evaluating PD-L1 in GCTs. The SII was calculated using platelet (P), neutrophil (N) and lymphocyte (L) counts before chemotherapy and correlated with survival using regression analyses and Kaplan–Meier method. Results: In the discovery cohort, the SII was associated with poor risk clinical features. Patients with low SII had significantly longer progression-free survival (HR=0.22, 95% CI 0.12–0.41, P<0.001) and overall survival (OS) (HR=0.16, 95% CI 0.08–0.32, P<0.001) compared to high SII. This index was independent of International Germ Cell Cancer Collaborative Group criteria in multivariable Cox regression analysis for OS and was validated in an independent cohort. When combining PD-L1 expression on tumour infiltrating lymphocytes (TILs) and SII, we identified three distinctive prognostic groups. Conclusions: High SII was associated with poor outcome in GCTs. Combination of PD-L1 positive TILs and SII could further refine prognosis in GCTs.

Abstract
PURPOSE Testicular germ cell tumors (TGCTs) are nearly universally curable malignancies. Nevertheless, standard cisplatin-based chemotherapy is not curative in a small subgroup of patients. Previously, we showed that PD-L1 overexpression is associated with worse prognosis in TGCTs, while tumor infiltrating lymphocytes (TILs) are prognostic in different types of cancer. This study aimed to evaluate the prognostic value of PD-1 and PD-L1 expressing TILs in TGCTs. RESULTS PD-L1 positive TILs were found significantly more often in seminomas (95.9% of patients) and embryonal carcinomas (91.0%) compared to yolk sac tumors (60.0%), choriocarcinomas (54.5%) or teratomas (35.7%) (All p < 0.05). TGCTs patients with high infiltration of PD-L1 positive TILs (HS ≥ 160) had significantly better progression-free survival (HR = 0.17, 95% CI 0.09 - 0.31, p = 0.0006) and overall survival (HR = 0.08, 95% CI 0.04 - 0.16, p = 0.001) opposite to patients with lower expression of PD-L1 (HS < 150). PD-1 expressing TILs were not prognostic in TGCTs. MATERIALS AND METHODS Surgical specimens from 240 patients with primary TGCTs were included into this translational study. The PD-1 and PD-L1 expression on tumor and TILs were detected by immunohistochemistry using anti-PD-1 and anti-PD-L1 monoclonal antibody. Scoring was performed semiquantitatively by weighted histoscore (HS) method. CONCLUSIONS The prognostic value of PD-L1 expressing TILs in TGCTs was demonstrated for the first time.

Abstract
Meckel-Gruber syndrome (MKS) is a rare lethal autosomal recessive disorder with typical anomalies including encephalocele, multicystic renal dysplasia, congenital liver fibrosis, and polydactyly. MKS is caused by mutations of genes localized on different chromosomes. Karyotypes of published Meckel-Gruber syndrome cases are without any aberrations. We present a male fetus with meningoencephalocele, multicystic renal dysplasia, congenital liver fibrosis, and other anomalies. Standard cytogenetic examination of cultured fetal skin and muscle fibroblasts showed mosaic trisomy 17. Homozygous deletion in CC2D2A gene was found by Sanger sequencing. This is to our knowledge the first case of genetically confirmed Meckel-Gruber syndrome with incidental cofinding of mosaic trisomy 17. Abnormal karyotype does not exclude diagnosis of MKS with risk of recurrence 25% in next pregnancy. In the case of anomalies typical for Meckel-Gruber syndrome, genetic analysis is indicated.

Abstract
Deregulated expression of microRNAs has the oncogenic or tumor suppressor function in cancer. Since miRNAs in plasma are highly stable, their quantification could contribute to more precise cancer diagnosis, prognosis and therapy prediction. We have quantified expression of seven oncomiRs, namely miR-17/92 cluster (miR-17, miR-18a, miR-19a and miR-20a), miR-21, miR-27a and miR-155, in plasma of 137 breast cancer (BC) patients. We detected down-regulation of six miRNAs in patients with invasive BC compared to controls; however, only miR-20a and miR-27a down-regulations were statistically significant. Comparing miRNA expression between early and advanced stages of BC, we observed statistically significant decrease of miR-17 and miR-19a. We identified down-regulation of miR-17 and miR-20a in patients with clinical parameters of advanced BC (lymph node metastasis, tumor grade 3, circulating tumor cells, higher Ki-67-related proliferation, hormone receptor negativity and HER2 amplification), when compared to controls. Moreover, decreased level of miR-17 was found from low to high grade. Therefore, miR-17 could represent an indicator of advanced BC. Down-regulated miR-27a expression levels were observed in all clinical categories regardless of tumor progression. Hence, miR-27a could be used as a potential diagnostic marker for BC. Our data indicates that any changes in miRNA expression levels in BC patients in comparison to controls could be highly useful for cancer-associated pathology discrimination. Moreover, dynamics of miRNA expression changes could be used for BC progression monitoring.

Abstract
BACKGROUND/AIM Annexin A2 (ANXA2) is a phospholipid-binding protein involved in fibrinolysis, cell proliferation, migration and metastatic dissemination. Circulating tumor cells (CTCs) are cells responsible for tumor dissemination and have a prognostic value in several types of cancers including breast cancer. Previously, we found correlation between CTCs and activation of coagulation. This study aimed to correlate CTCs with ANXA2 expression on CTCs, tumor cells and tumor associated stroma in primary breast cancer (PBC) patients. PATIENTS AND METHODS This prospective study included 101 PBC patients treated by primary surgery. CTCs were detected by quantitative real-time polymerase chain reaction (qRT-PCR) assay for the expression of epithelial (CK19) or epithelial-mesenchymal transition (EMT) genes [TWIST1, SNAI1, SNAI2, zinc finger E-box-binding homeobox 1 (ZEB1)]. ANXA2 expression on CTCs was detected by qRT-PCR, while expression of ANXA2 in tumor specimen was evaluated by immunohistochemistry and expressed by a weighted histoscore, evaluating both the percentage of positive cells and the intensity of membrane and cytoplasmic staining. Results of hormone receptors, HER2 status, B-cell lymphoma 2 (bcl-2) protein expression and protein p53 were reported as either positive or negative on histopathology report without further quantification. RESULTS CTCs were detected in 24.8% patients. Patients with epithelial CTCs had a significantly higher ANXA2 expression on CTCs than those of patients without CTCs (p=0.01). There was no association between CTCs and ANXA2 protein expression in tumor cells. However, patients, whom CTCs with EMT phenotype were detected in, had higher ANXA2 expression in tumor stroma when compared to those with absent EMT CTCs (p=0.04). Hormone-negative tumors had significantly higher ANXA2 expression in tumor cells compared to hormone-positive tumors (p=0.03). Similarly, tumors without bcl-2 protein expression had higher tumor levels of ANXA2 compared to tumor cells that were bcl-2 positive (p=0.05). CONCLUSION ANXA2 stromal expression might play a key role in aggressive tumor phenotype associated with increased EMT CTCs release, however, other factors beyond ANXA2 are responsible for coagulation activation mediated by CTCs in breast cancer patients.

Abstract
e16042 Background: Systemic immune-inflammation index (SII) and programmed death-ligand 1 (PD-L1) are prognostic in various types of malignancies. Recently we have shown a prognostic value of PD-L1 expression on tumor cells and tumor infiltrating lymphocytes (TILs) in testicular germ cell tumors (GCT). This study aimed to evaluate prognostic role of SII in a GCT population of patients expressing PD-L1 on TILs. Methods: SII was calculated using platelet (P), neutrophil (N) and lymphocyte (L) counts measured prior to chemotherapy (SII = P x N/L). SII was calculated in our discovery set of 216 patients with GCT treated at National Cancer Institute and St. Elisabeths' Cancer Institute between 1999 and 2015. A model with median obtained from the discovery data was tested in an independent validation set of 181 patients that were included in a retrospective study evaluating PD-L1 on TILs in GCT. PD-L1 on TILs was detected by immunohistochemistry and scored semiquantitatively by weighted histoscore method. SII was dichotomized into low and high categories based on median value. Results: Low SII ( < 1003) was found in 133 patients (73.5%) as opposed to 48 patients (26.5%) with high SII (≥ 1003). Ten (5.5%) and 171 patients (94.5%) from the validaton set had low (HS < 150) and high (HS ≥ 160) expression of PD-L1 on TILs, respectively. Discovery group of patients with high SII had significantly shorter PFS (HR = 4.48, 95% CI 2.44 – 8.23, p = 0.0000) and OS (HR = 6.10 95% CI 3.11 – 11.95, p = 0.0000) opposite to patients with low SII. PFS from validation set confirmed shorter PFS (HR = 3.03, 95% CI 3.86 – 7.46, p = 0.0062) and OS (HR = 6.49 95% CI 2.10 – 20.03, p = 0.0001) in patients with high versus low SII. A combined prognostic value of PD-L1 TILs and SII uncovered three prognostic groups. The best prognosis was observed in patients with low SII and high PD-L1 on TILs, the worst prognosis was seen in patients with high SII and low PD-L1 on TILs. Patients with SII and PD-L1 on TILs both values high or low had intermediate prognosis. Conclusions: SII was prognostic in our patients with GCT independently of international germ cell cancer collaborative group criteria, suggesting involvement of immune mechanisms in the behavior of GCT.

Abstract
Testicular germ cell tumors (TGCTs) represent a highly curable malignancy, however a small proportion of patients fails to be cured with cisplatin-based chemotherapy. Carbonic anhydrase IX (CA IX) is upregulated by hypoxia in several cancer types and correlates with a poor prognosis. The present translational study evaluated expression and prognostic value of CA IX in TGCTs. Surgical specimens from 228 patients with TGCTs were processed by the tissue microarray method and subjected to immunohistochemistry with the M75 monoclonal antibody. CA IX expression was evaluated in tumors vs. adjacent normal testicular tissues and correlated with clinicopathological characteristics and clinical outcome. CA IX expression was detected in 62 (30.2%) of TGCTs compared to 0 (0%) of normal tissue adjacent to testicular tumor (P<0.001). The highest frequency of the CA IX expression was detected in teratoma (39.0%), followed by seminoma (22.7%), yolk sac tumor (22.2%), embryonal carcinoma (11.9%) and choriocarcinoma (7.7%). None of germ cell neoplasias in situ (GCNIS) exhibited CA IX expression. Patients without the CA IX tumor expression showed significantly better progression-free survival, but not overall survival, compared to patients with the CA IX expression [hazard ratio (HR), 0.57; 95% CI, 0.32-1.02; P=0.037 and HR, 0.58; 95% CI, 0.29-1.16; P=0.088, respectively]. There was no significant correlation between the CA IX expression and clinicopathological variables. The intratumoral CA IX expression can serve as a prognostic marker in the TGCT patients. These results suggest that activation of the hypoxia-induced pathways may be important in the treatment failure in TGCTs patients.

Abstract
Despite the fact that testicular germ cell tumors (TGCTs) are one of the most chemosensitive solid tumors, a small proportion of patients fail to be cured following cisplatin-based first line chemotherapy. Upregulation of carbonic anhydrase IX (CA IX) in various solid tumors is associated with poor outcome. The current prospective study investigated the prognostic value of serum CA IX level in TGCTs. In total, 83 patients (16 non-metastatic following orchiectomy with no evidence of disease, 57 metastatic chemotherapy-naïve and 10 metastatic relapsed chemotherapy-pretreated) starting adjuvant and/or new line of chemotherapy and 35 healthy controls were enrolled in the study. Serum CA IX values were determined using an enzyme-linked immunosorbent assay, and intratumoral CA IX was analyzed by immunohistochemistry. Metastatic chemotherapy-naïve patients had significantly higher mean CA IX serum levels than healthy controls (490.6 vs. 249.6 pg/ml, P=0.005), while there was no difference in serum CA IX levels in non-metastatic or relapsed TGCT patients compared with healthy controls. There was no significant difference in the mean serum CA IX levels between different groups of patients and between the first and second cycle of chemotherapy, nor association with patients/tumor characteristics. Serum CA IX was not prognostic for progression-free survival [hazard ratio (HR)=0.81, P=0.730] or overall survival (HR=0.64, P=0.480). However, there was a significant association between intratumoral CA IX expression and serum CA IX concentration (rho=0.51, P=0.040). These results suggest that serum CA IX level correlates with tumor CA IX expression in TGCT patients, but fails to exhibit either a prognostic value or an association with patients/tumor characteristics.

Abstract
Background Germ cell neoplasia in situ (GCNIS), is preinvasive stage of testicular germ cell tumours (TGCTs). Fibrillins, which are integral components of microfibrils are suggested to be involved in cancer pathogenesis and maintenance of embryonic stem cells pluripotency. The aim of this study was to examine fibrillin-1 (FBN-1) expression in TGCTs patients. Methods Surgical specimens from 203 patients with TGCTs were included into the translational study. FBN-1 expression was evaluated in the tumour tissue, in GCNIS and in adjacent non-neoplastic testicular tissue in all available cases. Tissue samples were processed by the tissue microarray method. FBN-1 was detected by immunohistochemistry using goat polyclonal antibody and the expression was evaluated by the multiplicative quickscore (QS). Results The highest FBN-1 positivity was detected in GCNIS (mean QS = 11.30), with overexpression of FBN-1 (QS >9) in the majority (77.1 %) of cases. Expression of FBN-1 in all subtypes of TGCTs was significantly lower in comparison to expression in GCNIS (all p <0.001). Seminoma had significantly higher expression compared to EC, ChC and TER (all p <0.05), but not to YST (p = 0.84). In non-neoplastic testicular tissue the FBN-1 positivity was very low (mean QS = 0.02). Sensitivity, specificity, positive and negative predictive value of FBN-1 expression for diagnosis of GCNIS were 97.1, 98.8, 98.6 and 97.7 %. Conclusions FBN-1 is overexpressed in TGCTs and especially in GCNIS when compared to non-neoplastic testicular tissue in patients with germ cell tumors and could be involved in germ cell neoplasia in situ development.

Abstract
Circulating tumor cells (CTCs) are independent prognostic factors in the primary and metastatic breast cancer patients and play crucial role in hematogenous tumor dissemination. The aim of this study was to correlate the presence of CTCs in peripheral blood with the expression of proteins in tumor tissue that have a putative role in regulation of cell growth and metastatic potential. This prospective study included 203 primary breast cancer patients treated by definitive surgery. CTCs were detected by quantitative real-time PCR for the expression of epithelial (CK19) or epithelial-to-mesenchymal transition–inducing transcription factor genes (TWIST1, SNAIL1, SLUG, and ZEB1). Expression of APC, ADAM23, CXCL12, E-cadherin, RASSF1, SYK, TIMP3, BRMS1, and SOCS1 proteins in primary breast tumor tissue was evaluated by immunohistochemistry. CTCs with epithelial markers were found in 17 (9.2%) patients. Their occurrence was associated with inhibition of SOCS1 expression (odds ratio [OR] = 0.07; 95% confidence interval [CI], 0.03-0.13; P < .001). CTCs with positive epithelial-to-mesenchymal transition markers were detected in 30 (15.8%) patients; however, no association with analyzed protein expressions was found. Overall, CTCs were detected in 44 (22.9%) patients. Presence of any CTC marker was significantly associated with positive CXCL12 expression (OR = 3.08; 95% CI, 1.15-8.26; P = .025) and lack of SOCS1 expression (OR = 0.10; 95% CI, 0.04-0.25; P < .001) in patient’s tumor tissues. As both CXCL12 and SOCS1 proteins are involved in cytokine signaling, our results provide support for the hypothesis that aberrant signaling cross talk between cytokine and chemokine responses could have an important role in hematogenous dissemination of tumor cells in breast cancer.

Abstract
Background Cytokines are involved in cancer invasion and metastasis. Circulating tumor cells (CTCs) play key role in tumor dissemination and are an independent survival predictor in breast cancer patients. The aim of this study was to assess correlation between CTCs and plasma cytokines in primary breast cancer (PBC) patients. Methods This study included 147 chemotherapy naïve PBC patients. Peripheral blood mononuclear cells (PBMC) were depleted of hematopoetic cells using RossetteSep™ negative selection kit. RNA extracted from CD45-depleted PBMC was interrogated for expression of EMT (Twist1, Snail1, Slug, Zeb1) and epithelial (Ck19) gene transcripts by qRT-PCR. The concentrations of 51 plasma cytokines were measured using multiplex bead arrays. Results CTCs were detected in 25.2 % patients. CTCs exhibiting only epithelial markers (CTC_EP) and only EMT markers (CTC_EMT) were present evenly in 11.6 % patients, while CTCs co-expressing both markers were detected in 2.0 % patients. Patients with presence of CTC_EP in peripheral blood had significantly elevated levels of plasma IFN-α2, IL-3, MCP-3, β-NGF, SCF, SCGF-β, TNF-β and SDF-1 compared to patients without CTC_EP. CTC_EP exhibited overexpression of SDF-1 receptor and CXCR4, but not other corresponding cytokine receptor, and in multivariate analysis SDF-1 was independently associated with CTC_EP. There was an inverse correlation between CTC_EMT and plasma cytokines CTACK, β-NGF and TRAIL, while presence of either subtype of CTCs was associated with increased level of TGF-β2. Conclusion Using cytokine profiling, we identified cytokines associated with CTCs subpopulations in peripheral blood of PBC. Our data suggest that CXCR4-SDF-1 axis is involved in mobilization and trafficking of epithelial CTCs.

Abstract
BACKGROUND Testicular germ cell tumors (TGCTs) belong to the most chemosensitive solid tumors; however, a small proportion of patients fail to be cured with cisplatin-based chemotherapy. Inhibitors of PD-1/PD-L1 pathways represent a new class of promising drugs in anticancer therapy. The aim of this study was to evaluate expression and prognostic value of PD-1 and PD-L1 in TGCTs. PATIENTS AND METHODS Surgical specimens from 140 patients with TGCTs (131 with primary testicular tumor and 9 with extragonadal GCTs) were included into the translational study. PD-1 and PD-L1 expression was detected in the tumor tissue by immunohistochemistry using monoclonal antibodies, scored by the multiplicative quickscore (QS) method, compared with their expression in normal testicular tissue and correlated with clinicopathological characteristics and clinical outcome. RESULTS None of the GCTs exhibited PD-1 protein, although expression of PD-L1 was significantly higher in GCTs in comparison with normal testicular tissue (mean QS = 5.29 versus 0.32, P < 0.0001). Choriocarcinomas exhibit the highest level of PD-L1 with decreasing positivity in embryonal carcinoma, teratoma, yolk sac tumor and seminoma. PD-L1 expression was associated with poor prognostic features, including ≥3 metastatic sites, increased serum tumor markers and/or non-pulmonary visceral metastases. Patients with low PD-L1 expression had significantly better progression-free survival [hazard ratio (HR) = 0.40, 95% confidence interval (CI) 0.16-1.01, P = 0.008] and overall survival (HR = 0.43, 95% CI 0.15-1.23, P = 0.040) compared with patients with high PD-L1 expression. CONCLUSIONS In this translational study, we showed, for the first time, the prognostic value of PD-L1 expression in TGCTs and our data imply that the PD-1/PD-L1 pathway could be a novel therapeutic target in TGCTs.

Abstract
BACKGROUND Circulating tumor cells (CTCs) play a crucial role in tumor dissemination and are an independent survival predictor in breast cancer (BC) patients. Epithelial to mesenchymal transition (EMT) is involved in cancer invasion and metastasis. The aim of this study was to assess correlation between CTCs and expression of EMT transcription factors TWIST1 and SLUG in breast tumor tissue. METHODS This study included 102 early BC patients treated by primary surgery. Peripheral blood mononuclear cells (PBMC) were depleted of hematopoietic cells using RossetteSep™ negative selection kit. RNA extracted from CD45-depleted PBMC was interrogated for expression of EMT (TWIST1, SNAIL1, SLUG, FOXC2 and ZEB1) and epithelial (KRT19) gene transcripts by qRT-PCR. Expression of TWIST1 and SLUG in surgical specimens was evaluated by immunohistochemistry and quantified by multiplicative score. RESULTS CTCs were detected in 24.5 % patients. CTCs exhibiting only epithelial markers were present in 8.8 % patients, whereas CTCs with only EMT markers were observed in 12.8 % of pts and CTCs co-expressing both markers were detected in 2.9 % pts. We observed lack of correlation between CTCs and expression of TWIST1 and SLUG in breast cancer cells or cancer associated stroma. Lack of correlation was observed for epithelial CTCs as well as for CTCs with EMT. CONCLUSIONS In this translational study, we showed a lack of association between CTCs and expression of EMT-inducing transcription factors, TWIST1 and SLUG, in breast tumor tissue. Despite the fact that EMT is involved in cancer invasion and metastasis our results suggest, that expression of EMT proteins in unselected tumor tissue is not surrogate marker of CTCs with either mesenchymal or epithelial features.

Abstract
More than 25% of the patients with breast cancer (BC) develop metastatic disease. In the present study, we investigated the relationship between DNA methylation levels in genes regulating cell growth, invasiveness, and metastasis and advanced BCs and evaluated the clinical utility of methylation profiles for detecting metastatic potential. Pyrosequencing was used to quantify methylation levels in 11 cancer-associated genes in primary tumors (PTs), lymph node metastases (LNMs), plasma (PL), and blood cells from 206 patients with invasive BC. Protein expression was evaluated using immunohistochemistry. PTs showed hypermethylation of A isoform of the RAS-association domain family 1 (RASSF1A), adenomatous polyposis coli (APC), chemokine C-X-C motif ligand 12 (CXCL12), and disintegrin and metalloprotease domain 23 (ADAM23) (means 38.98%, 24.84%, 12.04%, and 10.01%, respectively). Positive correlations were identified between methylations in PTs and LNMs, but not between PL and PTs. The cumulative methylation of PTs and LNMs manifested similar spectrums of methylated genes that indicate the maintaining of aberrant methylation during breast tumorigenesis. Significantly increased methylation levels in RASSF1A, APC, CXCL12, and ADAM23 were found in estrogen receptor (ER) positive BCs in comparison with ER negative cases. Regarding these results, the evaluation of DNA methylation could be more informative in testing of patients with ER positive BC. The risk for LNMs development and higher proliferation of cancer cells measured through Ki-67 expression was increased by hypermethylation of CXCL12 and ADAM23, respectively. Therefore, the quantification of CXCL12 and ADAM23 methylation could be useful for the prediction of advanced stage of BC.

Abstract
Background Metastatic spread of tumor cells remains a serious problem in cancer treatment. Gene-directed enzyme/prodrug therapy mediated by tumor-homing genetically engineered mesenchymal stromal cells (MSC) represents a promising therapeutic modality for elimination of disseminated cells. Efficacy of gene-directed enzyme/prodrug therapy can be improved by combination of individual systems. We aimed to define the combination effect of two systems of gene therapy mediated by MSC, and evaluate the ability of systemically administered genetically engineered mesenchymal stromal cells to inhibit the growth of experimental metastases derived from human breast adenocarcinoma cells MDA-MB-231/EGFP. Methods Human adipose tissue-derived mesenchymal stromal cells (AT-MSC) were retrovirally transduced with fusion yeast cytosine deaminase::uracil phosphoribosyltransferase (CD::UPRT) or with Herpes simplex virus thymidine kinase (HSVtk). Engineered MSC were cocultured with tumor cells in the presence of prodrugs 5-fluorocytosin (5-FC) and ganciclovir (GCV). Combination effect of these enzyme/prodrug approaches was calculated. SCID/bg mice bearing experimental lung metastases were treated with CD::UPRT-MSC, HSVtk-MSC or both in combination in the presence of respective prodrug(s). Treatment efficiency was evaluated by EGFP-positive cell detection by flow cytometry combined with real-time PCR quantification of human cells in mouse organs. Results were confirmed by histological and immunohistochemical examination. Results We demonstrated various extent of synergy depending on tested cell line and experimental setup. The strongest synergism was observed on breast cancer-derived cell line MDA-MB-231/EGFP. Systemic administration of CD::UPRT-MSC and HSVtk-MSC in combination with 5-FC and GCV inhibited growth of MDA-MB-231 induced lung metastases. Conclusions Combined gene-directed enzyme/prodrug therapy mediated by MSC exerted synergic cytotoxic effect and resulted in high therapeutic efficacy in vivo.

Abstract
Cancer is a risk factor for venous thromboembolism (VTE) and plasma d-dimer (DD) and tissue factor (TF) are established VTE associated markers. Circulating tumor cells (CTCs) are associated with the risk of VTE in metastatic breast cancer. This study aimed to correlate CTCs, blood coagulation and the urokinase plasminogen activator (uPA) system in primary breast cancer (PBC) patients. This prospective study included 116 PBC patients treated by primary surgery. CTCs were detected by quantitative RT-PCR assay for expression of epithelial (CK19) or epithelial-mesenchymal transition (EMT) genes (TWIST1, SNAIL1, SLUG, ZEB1, FOXC2). Plasma DD, TF, uPA system proteins were detected by enzyme-linked immunosorbent assays, while expressions of uPA system in surgical specimens were evaluated by immunohistochemistry. CTCs were detected in 27.6% patients. Patients with CTCs had a significantly higher mean plasma DD (ng/mL) than those of patients without CTCs (632.4 versus 365.4, p = 0.000004). There was no association between plasma TF and CTCs. Epithelial CTCs exhibit higher expression of uPA system genes compared to EMT_CTCs. Patients with CTCs had higher plasma uPA proteins than those of patients without CTCs; there was no correlation between tissue expression of uPA system, CTCs, DD or TF levels. In multivariate analysis CTCs and patients age were independent factors associated with plasma DD. We found association between plasma DD and CTCs indicating a potential role for activation of the coagulation cascade in the early metastatic process. CTCs could be directly involved in coagulation activation or increased CTCs could be marker of aggressive disease and increased VTE risk.

Abstract
Background Matrix metalloproteinases (MMPs) are involved in cancer invasion and metastasis. Circulating tumor cells (CTCs) play role in tumor dissemination and are an independent survival predictor in breast cancer (BC) patients. The aim of this study was to assess correlation between CTCs and tumor MMP1 in BC. Methods Study included 149 primary BC patients treated by surgery from March 2012 to March 2013. Peripheral blood mononuclear cells (PBMC) were depleted of hematopoietic cells using RossetteSepTM selection kit. RNA extracted from CD45-depleted PBMC was interrogated for expression of EMT (TWIST1, SNAIL1, SLUG, ZEB1) and epithelial (CK19) gene transcripts by qRT-PCR. Patient samples with higher epithelial and/or mesenchymal gene transcripts than those of healthy donors (n = 60) were considered as CTC positive. Expression of MMP1 in surgical specimens was evaluated by immunohistochemistry. Results CTCs were detected in 24.2% patients. CTCs exhibiting only epithelial markers were present in 8.7% patients, whereas CTCs with epithelial-mesenchymal transition (EMT) markers (CTC_EMT) were observed in 13.4% of patients and CTCs co-expressing both markers were detected in 2.0% patients. Patients with CTC_EMT in peripheral blood had significantly increased expression of MMP1 in tumor cells (p = 0.02) and tumor associated stroma (p = 0.05) than those of patients without CTC_EMT. In multivariate analysis, CTC_EMT and tumor grade were independently associated with MMP1 expression in cancer cells, while CTC_EMT and Ki67 were independently associated with MMP1 expression in cancer associated stroma. Conclusion Our data suggest link between MMP1 and CTCs with EMT phenotype and support role of MMPs and EMT in tumor dissemination.

Abstract
Abstract
Background: Cancer is a risk factor for venous thromboembolism (VTE) and plasma D-dimer (DD) and tissue factor (TF) are established blood markers associated with VTE. CTCs are an independent predictor of survival in early and metastatic breast cancer (BC) patients (pts) and CTCs are associated with the risk of VTE in metastatic BC pts. In this study, we hypothesized correlation between plasma DD and TF with presence of CTCs. Moreover, we hypothesized, that activation of urokinase plasminogen activator system (uPA) could be involved in CTCs released into peripheral blood (PB) as well as coagulation activation.
Methods: This prospective study included 119 early BC patients treated by primary surgery followed by systemic therapies when indicated, at the NCI in Slovakia from March to December 2012. Isolated peripheral blood mononuclear cells (PBMC) were depleted of hematopoietic cells (CD45+) using RossetteSepTM negative selection kit. RNA extracted from CD45-depleted PBMC was interrogated for expression of EMT-inducing transcription factors (TWIST1, SNAIL1, SLUG, ZEB1) and epithelial (CK19) gene transcripts by qRT-PCR. Expressions of gene transcripts in CD45- PBMC of pts and healthy donors (HD) were compared. Patient samples with higher epithelial and/or mesenchymal gene transcripts than those of HD (n = 60) were considered as CTC positive. Plasma DD, TF, uPA (urokinase-type plasminogen activator) and PAI-1 (plasminogen activator inhibitor) levels were detected by ELISA, while expressions of TF and uPA system in surgical specimens were evaluated by immunohistochemistry.
Results: CTCs were detected in 27.7% pts. The majority of CTCs exhibited either epithelial differentiation (13.5% pts) or mesenchymal phenotype (EMT markers in 15.1% of pts). A small fraction of CTCs showed co-expression of both markers (0.8%). Pts with any CTCs in PB had significantly higher mean ± SEM plasma DD levels (ng/mL) than those of pts without CTCs (632.4 ± 75.9 vs. 365.4 ± 47.0, p = 0.00002). This association was observed for both, epithelial CTCs (688.4 ± 110.4 vs. 400.7 ± 43.5 (p = 0.026) and mesenchymal CTCs (573.1 ± 105.8 vs. 415.6 ± 44.7, p = 0.0007). There was no association between plasma TF levels or breast tumor TF expression and CTCs. Patients with any CTCs had higher mean ± SEM plasma uPA (ng/mL) (374.6 ± 32.6 vs. 307.1 ± 20.3, p = 0.02) and PAI-1 (pg/mL) levels (5.3 ± 0.7 vs. 4.4 ± 0.4, p = 0.28), than those of patients without CTCs, however, there was no correlation between plasma uPA system activation and DD or TF levels. In multivariate analysis CTCs, patients age and tumor grade were independent factors associated with plasma DD levels.
Conclusion: This prospective study showed for the first time a positive association between plasma D-dimer levels and CTCs indicating a potential role for activation of the coagulation cascade in the early metastatic process. We hypothesize that CTCs could be directly involved in coagulation activation in breast cancer patients, or alternatively an increased CTCs count could be a marker of more aggressive disease and increased risk of VTE. Future studies will need to address the prognostic implications of these observations with the potential for therapeutic interventions for the metastatic process.

Abstract
BACKGROUND Poly(ADP-ribose)polymerase (PARP) inhibitors represent a new class of promising drugs in anticancer therapy. AIMS To evaluate PARP expression in testicular germ cell tumours (GCTs) and to correlate expression patterns with clinicopathological variables. METHODS In this translational study, tumour specimens from 124 patients with GCTs (114 patients with testicular primary tumours and 10 with extragonadal GCTs) were identified. PARP expression was detected by immunohistochemistry using monoclonal antibodies, scored by the multiplicative quickscore (QS) method and compared to PARP expression in normal testicular tissue. RESULTS We observed higher expression of PARP in testicular tumours compared to normal testicular tissue (mean QS=10.04 vs 3.31, p<0.0000001). Mean QS±SD for each histological subtype was as follows: intratubular germ cell neoplasia unclassified (IGCNU)=18.00±0.00, embryonal carcinoma=9.62±5.64, seminoma=9.74±6.51, yolk sac tumour=7.8±7.20, teratoma=5.87±5.34, and choriocarcinoma=4.50±8.33. The PARP overexpression (QS>9) was most often detected in IGCNU (100% of specimen with PARP overexpression), seminona (52.6%), embryonal carcinoma (47.0%), yolk sac tumour (33.3%), teratoma (26.7%) and choriocarcinoma (25.0%), compared to 1.9% of normal testicular tissue specimens. There was no association between PARP expression and clinical variables. CONCLUSIONS In this pilot study, we showed for the first time, that PARP is overexpressed in testicular germ cell tumours compared to normal testis.

Abstract
Nowadays valid classification of gestational trophoblastic disease, according to the World Health Organisation from the year 2003, divides gestational trophoblastic disease into three groups - molar pregnancies, non-neoplastic non-molar changes of trophoblast and tumours of trophoblast. To the molar pregnancies belong complete, partial, invasive and metastatic hydatidiform mole. In the differential diagnosis it is important to distinguish the complete hydatidiform mole from other forms of gestational trophoblastic disease, because there is an increased risk of malignant transformation of trophoblast cells in complete hydatidiform mole. 10 cases of genetically confirmed diploid complete mole and 10 cases of genetically confirmed triploid partial mole were included into our retrospective study. All cases were examined microscopically in the basic haematoxillin and eosin staining and immunohistochemically with the use of antibodies against human choriogonadotropin hormone, placental alkaline phosfatase and protein p57. Villous cytotrophoblast, stromal villous cells, extravillous trophoblast and decidual cells were p57 positive in all cases of partial hydatidiform mole. All 10 cases of complete hydatidiform mole were p57 negative in stromal villous cells and villous cytotrophoblast. P57 protein is a marker distinguishing complete hydatidiform moles from partial moles.

Abstract
e15027 Background: Testicular germ-cell tumours (TGCTs) represent a model for the cure of cancer. Nonetheless, a small proportion of patients develop disease recurrence. PARP inhibitors represent a new class of promising drugs in anticancer therapy. The aim of this study was to evaluate poly(ADP-ribose)polymerase-1 (PARP1) expression in TGCTs and to correlate expression patterns with clinico-pathological variables. Methods: In this translational study, tumor specimens from 124 patients with GCTs were identified. PARP1 expression was detected by immunohistochemistry using monoclonal antibody, scored by the multiplicative quickscore (QS) method and compared to PARP1 expression in testicular tissue of normal testis. The QS was calculated by multiplying the percentage score by the staining intensity score to yield a minimum value of 0 and a maximum value of 18. Based on the QS nuclear PARP1 expression was graded as low (0–9) or high (10–18). Results: We observed higher expression of PARP1 in testicular tumors compared to normal tissue of testis (mean QS = 10.04 vs. 3.60, p < 0.0000001). Mean QS ± SD for each histological subtype was following: intratubular germ cell neoplasia (ITGCN) = 18.00 ± 0.00, embryonal carcinoma = 9.62 ± 5.64, seminoma = 9.74 ± 6.51, yolc sac tumor = 7.8 ± 7.20, teratoma = 5.87 ± 5.34, and choriocarcinoma = 4.50 ± 8.33. The PARP1 overexpression (QS > 9) was most often detected in ITGCN (100% of specimen with PARP1 overexpression), seminona (52.6%), embryonal carcinoma (47.0%), yolc sac tumor (33.3%), teratoma (26.7%), and choriocarcinoma (25.0%), compared to 1.9% of normal testicular tissue specimen. There was no association between PARP1 expression and clinical variables. Conclusions: PARP1 overexpression is an early event in the development of TGCTs. We suggest that PARP1 could represent a novel treatment target in TGCTs and the assessment of PARP1 expression in tumor samples may lead to the consideration of TGCTs patients for PARP inhibitor therapy.

Abstract
OBJECTIVES Familial adenomatous polyposis (FAP) is an autosomal dominant disease characterized by the presence of hundreds to thousands of benign polyps in the colon. If not removed prophylactically they represent a risk of developing malignant cancer with an almost 100% penentrance. FAP is induced by germline mutation in the APC gene. Tumorigenesis launched a second somatic mutation of APC gene allele, leading to synthesis of non-functional APC protein. One of the possibilities of cancer prevention could be an alternative gene therapy using bacteria as vectors for delivery of therapeutic protein molecules. MATERIAL AND METHODS For this purpose mice model APC+/APC1638N with mutation in one allele murine homolog of the APC gene were used. Mice were fed orally commercial nutrition enriched with 0.5 ml PBS buffer with 5% milk containing 5×108 recombinant bacterial cells DE3plys6 bearing plasmid with cloned APC gene twice a week during 42 weeks. Afterwords mice were killed by thiopental, gastrointestinal tracts were removed, microscopically, macroscopically inspected for polyps/neoplastic lesions and immunohistochemically investigated with polyclonal rabbit antibody against APC protein. RESULTS We have cloned full-lenght APC gene into vector for expression in bacterial cells Escherichia coli BL21(DE3) and BL21(DE3) pLysS. Expression of the APC protein, induced by IPTG, was detected in protein extracts of three bacterial clones: DE3104-11, DE3pLys5, DE3pLys6. APC protein was identified by Western blot analysis using monoclonal and polyclonal antibodies against the APC protein. Bacteria of clone DE3pLys6 were orally administered to APC+/APC1638N mice with mutations in the APC gene. All transgenic mice without therapy developed adenomatous polyps in the gastrointestinal tract. Transgenic mice treated by oral administration of bacteria expressing functional APC protein developed polyps in 33.3%. The remaining four mice 66.7% were without polyps development. CONCLUSION Administration of APC gene expressing by bacteria to transgenic mice with mutation in APC gene leads to reduction in the number of mice developing polyps in the gastrointestinal tract. The effect of bacterially expressed APC protein in elimination of intestinal polyps or tumors has been monitored. These are our preliminary results and for possible confirmation of our hypotheses still more research is needed.
