The Collagen Receptor uPARAP in Malignant Mesothelioma: A Potential Diagnostic Marker and Therapeutic Target. Int J Mol Sci 2021; 22:ijms222111452. [PMID: 34768883 PMCID: PMC8583732 DOI: 10.3390/ijms222111452] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2021] [Revised: 10/19/2021] [Accepted: 10/20/2021] [Indexed: 12/13/2022] Open
Abstract
Malignant mesothelioma (MM) is a highly aggressive cancer with limited therapeutic options. We have previously shown that the endocytic collagen receptor, uPARAP, is upregulated in certain cancers and can be therapeutically targeted. Public RNA expression data display uPARAP overexpression in MM. Thus, to evaluate its potential use in diagnostics and therapy, we quantified uPARAP expression by immunohistochemical H-score in formalin-fixed paraffin-embedded bioptic/surgical human tissue samples and tissue microarrays. We detected pronounced upregulation of uPARAP in the three main MM subtypes compared to non-malignant reactive mesothelial proliferations, with higher expression in sarcomatoid and biphasic than in epithelioid MM. The upregulation appeared to be independent of patients’ asbestos exposure and unaffected after chemotherapy. Using immunoblotting, we demonstrated high expression of uPARAP in MM cell lines and no expression in a non-malignant mesothelial cell line. Moreover, we showed the specific internalization of an anti-uPARAP monoclonal antibody by the MM cell lines using flow cytometry-based assays and confocal microscopy. Finally, we demonstrated the sensitivity of these cells towards sub-nanomolar concentrations of an antibody-drug conjugate formed with the uPARAP-directed antibody and a potent cytotoxin that led to efficient, uPARAP-specific eradication of the MM cells. Further studies on patient cohorts and functional preclinical models will fully reveal whether uPARAP could be exploited in diagnostics and therapeutic targeting of MM.

Abstract
Background Malignant pleural mesothelioma (MPM) is a rare malignant tumor associated with asbestos exposure, with infaust prognosis and overall survival below 20 months in treated patients. Platinum is still the backbone of the chemotherapy protocols, and the reasons for the rather poor efficacy of platinum compounds in MPM remain largely unknown. Therefore, we aimed to analyze differences in key signaling pathways and biological mechanisms in therapy-naïve samples and samples after chemotherapy in order to evaluate the effect of platinum-based chemotherapy. Methods The study cohort comprised 24 MPM tumor specimens, 12 from therapy-naïve and 12 from patients after platinum-based therapy. Tumor samples were screened using the NanoString nCounter platform for digital gene expression analysis with an appurtenant custom-designed panel comprising a total of 366 mRNAs covering the most important tumor signaling pathways. Significant pathway associations were identified by gene set enrichment analysis using the WEB-based GEne SeT AnaLysis Toolkit (WebGestalt) Results We have found reduced activity of TNF (normalized enrichment score: 2.03), IL-17 (normalized enrichment score: 1.93), MAPK (normalized enrichment score: 1.51), and relaxin signaling pathways (normalized enrichment score: 1.42) in the samples obtained after platinum-based therapy. In contrast, AMPK (normalized enrichment score: –1.58), mTOR (normalized enrichment score: –1.50), Wnt (normalized enrichment score: –1.38), and longevity regulating pathway (normalized enrichment score: –1.31) showed significantly elevated expression in the same samples. Conclusions We could identify deregulated signaling pathways due to a directed cellular response to platinum-induced cell stress. Our results are paving the ground for a better understanding of cellular responses and escape mechanisms, carrying a high potential for improved clinical management of patients with MPM.

RRM1 and ERCC1 as biomarkers in patients with locally advanced and metastatic malignant pleural mesothelioma treated with continuous infusion of low-dose gemcitabine plus cisplatin. BMC Cancer 2021; 21:892. [PMID: 34353292 PMCID: PMC8340445 DOI: 10.1186/s12885-021-08287-5] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2020] [Accepted: 05/04/2021] [Indexed: 12/29/2022] Open
Abstract
BACKGROUND Malignant Pleural Mesothelioma (MPM) is a rare but aggressive neoplasia that usually presents at advanced stages. Even though some advances have been achieved in the management of patients with MPM, this malignancy continuous to impose a deleterious prognosis for affected patients (12-18 months as median survival, and 5-10% 5-year survival rate), accordingly, the recognition of biomarkers that allow us to select the most appropriate therapy are necessary. METHODS Immunohistochemistry semi-quantitative analysis was performed to evaluate four different biomarkers (ERCC1, RRM1, RRM2, and hENT-1) with the intent to explore if any of them was useful to predict response to treatment with continuous infusion gemcitabine plus cisplatin. Tissue biopsies from patients with locally advanced or metastatic MPM were analyzed to quantitatively asses the aforementioned biomarkers. Every included patient received treatment with low-dose gemcitabine (250 mg/m2) in a 6-h continuous infusion plus cisplatin 35 mg/m2 on days 1 and 8 every 3 weeks as first-line therapy. RESULTS From the 70 eligible patients, the mean and standard deviation (SD) for ERCC1, RRM1, RRM2 and hENT-1 were 286,178.3 (± 219, 019.8); 104,647.1 (± 65, 773.4); 4536.5 (± 5, 521.3); and 2458.7 (± 4, 983.4), respectively. Patients with high expression of RRM1 had an increased median PFS compared with those with lower expression (9.5 vs 4.8 months, p = < 0.001). Furthermore, high expression of RRM1 and ERCC1 were associated with an increased median OS compared with their lower expression counterparts; [(23.1 vs 7.2 months for RRM1 p = < 0.001) and (17.4 vs 9.8 months for ERCC1 p = 0.018)]. CONCLUSIONS ERCC1 and RRM1 are useful biomarkers that predict better survival outcomes in patients with advanced MPM treated with continuous infusion of gemcitabine plus cisplatin.

Abstract
Reserpine is a natural indole alkaloid isolated from Rauwolfia serpentina and has potent antioxidant, antimicrobial, and anti-mutagenic properties. Accordingly, this study aimed to investigate the effect of reserpine on DNA repair, cell proliferation, invasion and apoptosis in 7,12-dimethylbenz[a]anthracene(DMBA)-induced hamster buccal pouch (HBP) carcinogenesis. Transforming growth factor-β (TGF-β) was found to induce Smad2, 3 and 4 phosphorylation triggering Smad3/Snail mediated DNA repair proteins and Smad2/4 nuclear translocation. In contrast, reserpine inhibits TGF-β dependent Smad2/3/4 phosphorylation, thereby blockage Smad3/Snail activation and Smad2/4 nuclear translocation. Interruption of these oncogenic signaling pathways leads to downregulating ERCC1, XPF, Ku70, DNA-PKcs, PCNA, cyclin D1, HIF-1α, IL-6, Mcl-1 and stimulates Bax, cytochrome C, Apaf-1, caspase-9, caspase-3 and PARP protein expressions. This study provides therapeutic potential of reserpine in inhibiting DNA repair, cell proliferation, and invasion while simultaneously inducing apoptosis via modulation TGF-β signals.

Abstract
Malignant pleural mesothelioma (MPM) is a rare malignancy mainly caused by asbestos exposure. Germinal and acquired mutations in genes of DNA repair pathways, in particular of homologous recombination repair, are frequent in MPM. Here we overview the available experimental data suggesting that an impaired DNA repair system affects MPM pathogenesis by leaving lesions through the genome unresolved. DNA repair defects represent a vulnerability of MPM, and it seems plausible to propose that leveraging these deficiencies could have therapeutic potential for patients with MPM, for whom there is an urgent need of more effective therapies.

Double-staining Immunohistochemistry Reveals in Malignant Pleural Mesothelioma the Coexpression of ERCC1 and RRM1 as a Frequent Biological Event Related to Poorer Survival. Appl Immunohistochem Mol Morphol 2020; 29:231-238.

Abstract
Malignant pleural mesothelioma (MPM) is a rare cancer with a poor prognosis. To date, standard MPM therapy is still limited to surgery, radiotherapy, and chemotherapy, including pemetrexed and platinum compounds. The main mechanisms of platinum resistance are associated with DNA repair pathways. Excision repair cross-complementing group 1 (ERCC1) and ribonucleotide reductase subunit M1 (RRM1) are important components of the DNA repair, considered as prognostic and predictive biomarkers in various cancer types. The main goal of the present study was to investigate the ERCC1 and RRM1 expression and their potential impact on outcome in this tumor. A series of 73 MPM, mainly treated with a platin-based regimen, was collected and the immunohistochemistry tests were performed to assess ERCC1 and RRM1 expression. In addition, a multiplex immunohistochemistry has been validated to detect simultaneously the 2 proteins on the same slide. In our series, 36 of 73 cases showed ERCC1 expression and 55 of 73 showed RRM1 expression. The double immunohistochemical staining showed the coexpression of ERCC1/RRM1 in 34 of 73 cases. A significant association between ERCC1 and RRM1 expression was observed in our series (P<0.05). Patients with ERCC1/RRM1 coexpression experienced shorter median overall survival (6.6 vs. 13.8 mo, log-rank=7688; P=0.006). Our results suggest that the coexpression of ERCC1/RRM1 could define a group of MPM patients with the worst prognosis who should need likely alternative treatment. In conclusion, we propose the putative usefulness of ERCC1/RRM1 coexpression as prognostic biomarkers for overall survival in MPM.

Abstract
Objective Calretinin is a well-known immunohistochemical tissue marker in the diagnosis of malignant mesothelioma. Promising results also indicate the use in early detection. In the present cross-sectional survey, correlations of calretinin plasma levels with clinical features were investigated. Plasma samples of 60 patients with malignant pleural mesothelioma (MPM) and 111 cancer-free controls formerly exposed to asbestos were compared. Calretinin concentrations were determined in plasma using an enzyme-linked immunosorbent assay (ELISA). Results The median concentration was higher in MPM patients than in controls (0.79 vs. 0.23 ng/ml; p < 0.0001). Patients with epithelioid MPM or biphasic MPM had higher calretinin plasma levels than patients with sarcomatoid MPM. Strong expression of calretinin in the tumor tissue was associated with higher plasma levels. Preoperative patients showed higher levels of calretinin than patients after thoracic surgery (1.20 vs. 0.67 ng/ml; p = 0.096). The suitability of plasma calretinin has been confirmed as a tumor marker in the differential diagnosis of epithelioid MPM. The value of plasma calretinin for therapy monitoring or as a prognostic marker should be further investigated.

Screening of Pleural Mesothelioma Cell Lines for Kinase Activity May Identify New Mechanisms of Therapy Resistance in Patients Receiving Platin-Based Chemotherapy. JOURNAL OF ONCOLOGY 2019; 2019:2902985. [PMID: 31929796 PMCID: PMC6942867 DOI: 10.1155/2019/2902985] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/04/2019] [Accepted: 12/03/2019] [Indexed: 11/23/2022]
Abstract
Background Malignant pleural mesothelioma (MPM) is a rare, predominantly asbestos-related and biologically highly aggressive tumor associated with a dismal prognosis. Multimodal therapy consisting of platinum-based chemotherapy is the treatment of choice. The reasons underlying the rather poor efficacy of platinum compounds remain largely unknown. Kinase activity might influence cellular response to these regimens. Materials and Methods For this exploratory study, we screened MPM cell lines (NCI-H2452, NCI-H2052, and MSTO-211H) differing in response to cisplatin and benign control fibroblasts (MRC-5) for overall phosphorylation patterns as well as kinase activity with respect to cellular response to cisplatin-based therapeutics. We analysed the cell lines for cellular kinases in a high-throughput manner using the highly innovative technique PamGene. Cell state analysis including apoptosis, necrosis, and cell viability was performed by using enzyme activity and fluorescent-based assays. Results Cisplatin alters cellular phosphorylation patterns affecting cell cycle, migration, adhesion, signal transduction, immune modulation, and apoptosis. In cisplatin-responsive cell lines, phosphorylation of AKT1 and GSK3B was decreased but could not be influenced in cisplatin-resistant NCI-H2452 cells. Cisplatin-responsive cell lines showed increased phosphorylation levels of JNK1/2/3 but decreased phosphorylation in cisplatin-resistant NCI-H2452 cells. Conclusion Kinase phosphorylation and activity might play a crucial role in cellular response to cytostatic agents. Cisplatin influences phosphorylation patterns with distinct features in cisplatin-resistant cells. These alterations exert a significant impact on cell cycle, migration, adhesion, signal transduction, immune modulation, and apoptosis of the respective tumor cells. Based on our results, the induction of p38 or JNK1/3, or inhibition of AKT1 by, for example, BIA-6, might offer a positive synergistic effect by induction of an apoptotic response to cisplatin-based treatment, thus potentially enhancing the clinical outcome of MPM patients.

Abstract
BACKGROUND Many studies have suggested that high KIF26B expression is directly linked to poor prognostic outcomes in breast cancer. However, the exact role of KIF26B in breast cancer progression is not fully understood. In this study, we aimed to explore the function and mechanism of KIF26B in breast cancer progression. METHODS Quantitative real-time PCR and immunohistochemistry analysis were used to detect KIF26B expression in breast cancer cell lines and patient samples. Cell proliferation was assessed by CCK-8 assay, and cell migration and invasion were evaluated by wound healing assay and transwell assay. Western blot analysis was carried out to assess the underlying molecular mechanisms. Tumor formation and metastasis were determined by in vivo mouse experiments. RESULTS KIF26B levels were significantly increased in breast cancer cells and patient samples. KIF26B level correlated with tumor size, TNM grade, and differentiation in patients with breast cancer. Overexpressing KIF26B in vitro promoted breast cancer cell proliferation and migration by activating FGF2/ERK signaling, while silencing KIF26B had the opposite effects. Similarly, KIF26B knockdown repressed tumor formation and metastasis in nude mice. CONCLUSION KIF26B promoted the development and progression of breast cancer and might act as a potential therapeutic target for treating breast cancer.

Abstract
Background Several studies in solid tumors have shown that expression of excision repair cross-complementation group 1 (ERCC1) and class III β-tubulin (TUBB3) can predict response to chemoradiotherapy and might be prognostic factors. We assessed the role of ERCC1 and TUBB3 expressions as predictive and prognostic factors in locally advanced cervical squamous cell carcinoma (LACSCC) patients treated with different neoadjuvant regimens. Methods ERCC1 and TUBB3 were detected in 88 patients with LACSCC by immunohistochemical analysis. Sixty-two patients were included in 3 different prospective trials and grouped as follows: vinorelbine or docetaxel (group A, n = 44) and ifosfamide-vinorelbine-cisplatin (group B, n = 18). Both groups were compared with standard cisplatin chemoradiotherapy (group C, n = 26). Clinical data at baseline, disease-free survival (DFS) and overall survival (OS) were also collected. Univariate and multivariate Cox models were used to analyze the risk factors. Results Thirty-five patients (39.8%) and 18 (20.5%) had high ERCC1 and TUBB3 expression, respectively. Both proteins were overexpressed in tumors with unfavorable characteristics. High ERCC1 was associated with advanced FIGO stage (p = 0.034) and progressive disease (49% vs. 28%). Poor DFS (p = 0.021) and OS (p = 0.005) were observed in group C patients with high ERCC1 expression. Multivariate analysis showed that ERCC1 expression, FIGO stage and pretreatment hemoglobin level were significant prognostic factors (p = 0.002, p = 0.008 and p = 0.005, respectively). Conclusions ERCC1 expression could be a predictive and prognostic factor in LACSCC patients who receive cisplatin monotherapy. Conversely, TUBB3 had no impact on survival in patients treated with antimicrotubule agents.

Platin-containing regimes are currently considered as state-of-the-art therapies in malignant pleural mesotheliomas (MPM) but show dissatisfying response rates ranging from 6 to 16% only. Still, the reasons for the rather poor efficacy remain largely unknown. A clear stratification of patients based on new biomarkers seems to be a promising approach to enhance clinical management, which would be a long-needed improvement for MPM patients but does not seem likely soon unless new biomarkers can be validated. Twenty-four formalin-fixed, paraffin-embedded (FFPE) tumour specimens were subjected to a miRNA expression screening of 800 important miRNAs using digital quantification via the nCounter technique (NanoString). We defined a small subset of miRNAs regulating the key enzymes involved in the repair of platin-associated DNA damage. Particularly, the TP53 pathway network for DNA damage recognition as well as genes related to the term "BRCAness" are the main miRNA targets within this context. The TP53 pathway network for DNA damage recognition as well as genes related to the term "BRCAness" are the main players for risk stratification in patients suffering from this severe disease. Taking the specific molecular profile of the tumour into account can help to enhance the clinical management prospectively and to smooth the way to better response prediction.

Abstract
Background: Malignant pleural mesothelioma (MPM) is a rare, predominantly asbestos-related and biologically highly aggressive tumour leading to a dismal prognosis. Multimodality therapy consisting of platinum-based chemotherapy is the treatment of choice. The reasons for the rather poor efficacy of platinum compounds remain largely unknown. Material and Methods: For this exploratory mRNA study, 24 FFPE tumour specimens were screened by digital gene expression analysis. Based on data from preliminary experiments and recent literature, a total of 366 mRNAs were investigated using a Custom CodeSet from NanoString. All statistical analyses were calculated with the R i386 statistical programming environment. Results: CDC25A and PARP1 gene expression were correlated with lymph node spread, BRCA1 and TP73 expression levels with higher IMIG stage. NTHL1 and XRCC3 expression was associated with TNM stage. CHECK1 as well as XRCC2 expression levels were correlated with tumour progression in the overall cohort of patients. CDKN2A and MLH1 gene expression influenced overall survival in this collective. In the adjuvant treated cohort only, CDKN2A, CHEK1 as well as ERCC1 were significantly associated with overall survival. Furthermore, TP73 expression was associated with progression in this subgroup. Conclusion: DNA-damage response plays a crucial role in response to platin-based chemotherapeutic regimes. In particular, CHEK1, XRCC2 and TP73 are strongly associated with tumour progression. ERCC1, MLH1, CDKN2A and most promising CHEK1 are prognostic markers for OS in MPM. TP73, CDKN2A, CHEK1 and ERCC1 seem to be also predictive markers in adjuvant treated MPMs. After a prospective validation, these markers may improve clinical and pathological practice, finally leading to a patients' benefit by an enhanced clinical management.

Abstract
One particular approach of multimodality treatment for mesothelioma is induction therapy followed by surgery. Among its several advantages, the most important is downstaging of the tumor into a resectable stage, although morbidity and mortality might be increased. In this article we review the principles and outcome of different modalities for induction treatment of mesothelioma.

Abstract
Malignant pleural mesothelioma (MPM) is a very aggressive form of cancer with a poor diagnosis and prognosis. The first line treatment for MPM is a combination of cisplatin and Pemetrexed, which displayed limited efficacy and severe side effects. The naturally occurring compound phenethyl isothiocyanate (PEITC) previously showed interesting anti-tumor properties on several cancer cell lines. We thus aim at evaluating PEITC used alone or in combination with cisplatin in order to improve MPM treatment. Nine MPM cell lines and primary mesothelial cells (PMC), co-cultured or not with M2 macrophages present in MPM microenvironment, were used to assess PEITC and cisplatin anti-tumor properties. Compounds were used alone or in combination. Both PEITC and cisplatin were cytotoxic on MPM cells in a dose dependent manner. We herein showed that PEITC-induced cytotoxicity was due to the generation of reactive oxygen species. Moreover, we showed that cisplatin-PEITC combination allowed the potentialization of both compounds' cytotoxic effects and prevented the emergence of resistant MPM cells. Interestingly, PMC were not sensitive to the combination. Finally, we showed that M2 macrophages did not alter the anti-tumor properties of the combination. Cisplatin-PEITC combination thus represents a promising strategy to induce a selective toxicity towards malignant cells.

Abstract
BACKGROUND To determine prognostic value of excision repair cross-complementation 1 (ERCC1) in patients with malignant pleural mesothelioma (MPM). MATERIALS AND METHODS The study included 60 patients with MPM who were diagnosed and treated in the Radiation Oncology Department of Kayseri Teaching Hospital and Medical Oncology Department of Erciyes University, Medicine School between 2005 and 2013. By using immunohistochemical methods, ERCC1 expression in biopsy specimens was evaluated. We retrospectively assessed whether there is a correlation between ERCC1 and response to anti-neoplastic therapy or survival. RESULTS There were 50 men and 10 women with median age of 62 years (range: 39-83). Histological type was epithelial mesothelioma in the majority of the cases (85%), most commonly presenting in stage four. Of the cases, 20 (33%) received radiotherapy, 60 (%100) received first-line chemotherapy and 15 (%25) received second-line chemotherapy. In the assessment after therapy, it was found that there was partial response in 12 cases (20%), stable disease in 19 cases (31.4%) and progression in 25 cases (41.7%). ERCC1 was positive in 43% of the cases. Mean OS was 11.7 months and mean DFS was 9.5 months in ERCC1-positive cases regardless of therapy, while they were 19.2 months and 17.1 months in ERCC1-negative cases, respectively. The difference was found to be significant (p<0.05). In univariate analysis, stage, comorbidity, response to treatment and ERCC1 expression were found to be significantly associated with OS (p=0.083; p=0.043; p=0.041; p=0.050). In multivariate analysis, response to treatment remained to be significant for OS (p=0.005). In univariate and multivariate analyses, response to treatment and ERCC1 were found to be significantly associated with DFS (p=0.049; p=0.041). CONCLUSIONS ERCC1 was identified as poor prognostic factor in patients with MPM.

Abstract
OBJECTIVES Survival and response to platinum-based induction chemotherapy are heterogeneous among patients with malignant pleural mesothelioma. The aim of the present study was to assess the prognostic role of DNA repair markers, such as excision repair cross-complementation group 1 and ribonucleotide reductase M1, in multimodally treated patients with malignant pleural mesothelioma. METHODS Tumor tissue of a malignant pleural mesothelioma cohort (n = 107) treated with platinum/gemcitabine (n = 46) or platinum/pemetrexed (n = 61) induction chemotherapy followed by extrapleural pneumonectomy was assembled on a tissue microarray. Immunohistochemical expression of excision repair cross-complementation group 1 (nuclear) and ribonucleotide reductase M1 (nuclear and cytoplasmic) was assessed for its prognostic impact (association with overall survival or freedom from recurrence). RESULTS Patients with high nuclear ribonucleotide reductase M1 expression before chemotherapy showed significantly longer freedom from recurrence (P = .03). When specifically analyzed in the subgroup of patients receiving platinum/gemcitabine followed by extrapleural pneumonectomy, high nuclear ribonucleotide reductase M1 was associated with prolonged freedom from recurrence (P = .03) and overall survival (P = .02). Low excision repair cross-complementation group 1 expression in prechemotherapy tumor tissues was associated with significantly longer freedom from recurrence (P = .04). Nuclear ribonucleotide reductase M1 and excision repair cross-complementation group 1 were independent prognosticators of freedom from recurrence in addition to pT stage in multivariate analysis. CONCLUSIONS In the present study, nuclear ribonucleotide reductase M1 and excision repair cross-complementation group 1 expression were identified as independent prognosticators for freedom from recurrence of malignant pleural mesothelioma in patients undergoing induction chemotherapy followed by extrapleural pneumonectomy.

Abstract
Background Patients with malignant mesothelioma have a poor prognosis and only 40% respond to first line treatment; a combination of pemetrexed and cisplatin or carboplatin. We used primary malignant mesothelioma cells and an ex vivo chemosensitivity assay with future purpose to predict best choice of treatment. The clinical outcome of these patients might be predicted by measuring drug sensitivity. Methods Pleural effusions containing primary malignant mesothelioma cells were received from the diagnostic routine. We characterized and tested the chemosensitivity of 18 malignant samples and four benign samples from 16 different patients with pleural effusions. Cells were seeded in a 384-well plate for a robotized ex vivo testing of drug sensitivity to 32 different drugs. The primary cells were further characterized by immunocytochemistry to evaluate the proportion of malignant cells and to study the RRM1 and ERCC1 reactivity, two proteins associated with drug resistance. Results We observed great individual variability in the drug sensitivity. Primary cell isolates were affected by between one and ten drugs, and resistant to the remaining tested drugs. Actinomycin D and daunorubicin were the two drugs effective in most cases. Adjusting efficiency of individual drugs for varying proportion of tumor cells and to the average effect on benign cells correlated with effect of pemetrexed, cisplatin and survival time. General drug sensitivity, proportion of malignant cells and reactivity to RRM1 correlated to each other and to survival time of the patients. Conclusions The proportion of malignant cells and RRM1 reactivity in the pleural effusions correlate to drug sensitivity and survival time. The variability in response to the commonly used chemotherapies emphasizes the need for tests that indicate best individual choice of cytotoxic drugs. The efficiency of the obtained results should preferably be corrected for admixture of benign cells and effects of given drugs on benign cells.

Abstract
Malignant pleural mesothelioma (MPM) is difficult to distinguish from reactive mesothelial proliferations (RMPs). It is uncertain whether miRNAs are useful biomarkers for differentiating MPM from RMPs. Thus, we screened with a quantitative RT-PCR (RT-qPCR)-based platform the expression of 742 miRNAs in formalin-fixed, paraffin-embedded, preoperative diagnostic biopsy samples, surgically resected MPM specimens previously treated with chemotherapy, and corresponding non-neoplastic pleura (NNP), from five patients. miR-126, miR-143, miR-145, and miR-652 were significantly down-regulated (≥twofold) in resected MPM and/or chemotherapy-naïve diagnostic tumor biopsy samples. The miRNA expression pattern was validated by RT-qPCR in a cohort of 40 independent MPMs. By performing binary logistic regression on the RT-qPCR data for the four miRNAs, the established four-miRNA classifier differentiated MPM from NNP with high sensitivity and specificity (area under the curve, 0.96; 95% CI, 0.92-1.00). The classifier's optimal logit(P) value of 0.62 separated NNP and MPM samples with a sensitivity of 0.95 (95% CI, 0.89-1.00), a specificity of 0.93 (95% CI, 0.87-0.99), and an overall accuracy of 0.94 (95% CI, 0.88-1.00). The level of miR-126 in MPM was inversely correlated with that of the known target, the large neutral amino acid transporter, small subunit 1 (r = -0.38; 95% CI, -0.63 to -0.06). Overall, these results indicate that these four miRNAs may be suitable biomarkers for distinguishing MPM from RMPs.

Abstract
SUMMARY Platinum-based chemotherapy regimens using cisplatin or carboplatin are the cornerstones of treatment for advanced non-small-cell lung cancer (NSCLC), small-cell lung cancer and malignant pleural mesothelioma. Despite being standard regimens of choice in the majority of patients without oncogene driver mutations, the activity obtained by individual patients varies considerably. Hence, biomarkers such as ERCC1 are needed to predict sensitivity to drugs, which has been explored as a predictor for platinum sensitivity in thoracic malignancies, mostly in the case of NSCLC. ERCC1 may be measured by mRNA activity; however, most studies have examined protein expression via immunohistochemistry. High ERCC1 expression has been a good prognostic factor in resected NSCLC patients who are not receiving chemotherapy, while it has been an adverse predictor for the effect of cisplatin or carboplatin. The latter has also been shown in malignant pleural mesothelioma. Heterogeneous distribution of ERCC1 within tumors may be a source of discordance in the results obtained in various studies. Adding to the discordance may be the fact that there are four isoforms of ERCC1 and seemingly only one of these accounts for cisplatin sensitivity. It is possible that the antibodies used may be equally specific for the same isoforms, which contributes to the heterogeneity of results, in addition to the contribution from immunohistochemistry cutoff levels. Robust evidence in support of the use of ERCC1 to select treatment on an individual patient basis is lacking, and such results from ongoing trials are eagerly awaited in order to improve the possibilities for individualized chemotherapy with improved outcomes.

Abstract
INTRODUCTION Platinum-based chemotherapy is besides the standard antifolate therapy with pemetrexed, the cornerstone for treatment of patients with malignant pleural mesothelioma (MPM), and its efficacy depends on several DNA repair enzymes. Therefore, these enzymes could be biomarkers for "tailoring" chemotherapy. This study evaluated enzymes involved in repair of platinum-caused DNA damage, potentially resulting in a biomarker panel associated with patient response and outcome to platinum-based chemotherapy. MATERIAL AND METHODS Pre- or posttreatment specimens from a total of 103 patients with MPM who were undergoing first-line chemotherapy were tested separately. Immunohistochemistry for ERCC1 (endonuclease excision repair cross-complementing 1), MLH1 (MutL homologue 1), MutS homologue (MSH) 2, MSH6, and βIII-tubulin protein expression, and pyrosequencing for ERCC1 codon 118 and C8092A polymorphisms were performed, and their results were correlated to clinicopathologic data. RESULTS ERCC1, MLH1, MSH2, MSH6, and βIII-tubulin were expressed in human MPM specimens at different intensities. When considering only pretreatment specimens, MSH6 protein levels were correlated to progression during chemotherapy (P = .0281). MLH1 protein levels (P = .0205), and ERCC1 codon 118 polymorphisms (P ≤ .0001) were significantly associated with progression-free survival. A significant association between ERCC1 protein levels and overall survival was noted (P = .032). Analyses of posttreatment specimens revealed significant associations between βIII-tubulin protein levels and progression-free survival (P = .0066). ERCC1 C8092A polymorphisms were significantly associated with progression-free survival and overall survival (P = .0463 and P = .0080, respectively) in this group. CONCLUSIONS Enzymes involved in DNA repair mechanisms are associated with patient response and outcome to platinum-based chemotherapy. Their assessment may be a helpful tool to tailor platinum-based chemotherapy of MPM patients who might expect the largest clinical benefit. Prospective validation of this biomarker panel is warranted.

Abstract
BACKGROUND Pemetrexed-based chemotherapy represents the standard of care in first-line treatment of advanced malignant pleural mesothelioma (MPM). However, there are no established predictors of clinical benefit. Pemetrexed inhibits multiple enzymes involved in pyrimidine and purine synthesis, but the main target is thymidylate synthase (TS). After cellular uptake pemetrexed is converted into more effective polyglutamated forms by folylpoly-γ-glutamate synthetase (FPGS). We hypothesized that FPGS and TS protein expressions are associated with clinical outcome after pemetrexed-based chemotherapy. METHODS Pretreatment tumor samples from 84 patients with histologically confirmed MPM, who received pemetrexed combined with platinum (79 of 84) or single-agent pemetrexed (5 of 84) as first-line treatment, were retrospectively analyzed. FPGS and TS protein expressions were semiquantitatively assessed by using the Hybrid (H)-scoring system (range, 0-300). H-scores were correlated with radiological response according to modified Response Evaluation Criteria in Solid Tumors, progression-free survival (PFS) and overall survival (OS). RESULTS Median H-score of the entire cohort was 230 for FPGS (range, 100-300), and 210 for TS (range, 100-300). High FPGS protein expression was significantly associated with longer PFS (pCOX = 0.0337), better objective tumor response (partial response versus stable disease + progressive disease; pKW = 0.003), and improved disease-control rate (partial response + stable disease versus progressive disease; pKW = 0.0208), but not with OS. In addition, high TS protein expression was associated with progressive disease under pemetrexed-based therapy (p = 0.0383), and shorter OS (pCOX = 0.0071), but no association with PFS was observed. CONCLUSION FPGS and TS expressions were associated with clinical response and outcome to pemetrexed-based first-line chemotherapy in MPM. Prospective evaluation of FPGS and TS expressions and their prognostic/predictive power in MPM patients is warranted.

Abstract
Malignant pleural mesothelioma is an extremely aggressive neoplasm of the pleura mainly attributable to asbestos exposure. Conventional medical, physical, and surgical treatments and their combinations are basically ineffective and just a few subjects experience some benefit. No definite guidelines can be provided in patient selection and therapeutic strategies. Currently, malignant pleural mesothelioma therapy is guided by clinical stage and patient characteristics, which are quite unreliable, rather than by the histological or molecular features of the tumor. In the present review the impact on prognosis of classic (i.e. etiology, age, gender, histology, staging), as well as relatively new clinical factors such as quality of life, positron emission tomography assessment, and occult residual disease, are firstly evaluated. In the second section of the review several biological variables and genetic markers, which have been recently recognized as the bases of the disease onset and development, are listed and discussed. There are serum and tissue markers. The latter are mainly related to cell cycle regulation, apoptosis, and growth factor pathways. These novel factors may play an important role in defining the prognosis of the disease and, subsequently, may have a place in addressing therapy.

Abstract
PURPOSE Malignant pleural mesothelioma (MPM) has a dismal prognosis. Treatment results may be improved by biomarker-directed therapy. We investigated the baseline expression and impact on outcome of predictive biomarkers ERCC1, BRCA1, and class III β-tubulin in a cohort of MPM patients treated with cisplatin-vinorelbine. We further explored the possibility of combining markers into a treatment-response profile to increase the predictive power. METHODS Formalin-fixed paraffin-embedded tumor specimens from 54 MPM patients included in a phase II trial were evaluated for ERCC1, BRCA1, and class III β-tubulin by immunohistochemistry (IHC). Immunostaining was quantified by an H-score and dichotomized according to upper quartile values. The ERCC1- and class III β-tubulin-status classified patients as treatment resistant (ERCC1 positive + class III β-tubulin positive) or treatment responsive (ERCC1 negative + class III β-tubulin negative). The remaining marker combinations were considered inconclusive. RESULTS Fifty patients had tumor tissue available for IHC. Eleven had a responsive profile, and nine had a resistant profile. Thirty patients had an inconclusive profile. Median progression-free survival (PFS) was 6.7 months in the treatment-resistant group, 15.3 months in the treatment-responsive group, and 8.1 months in the inconclusive group (log-rank p = 0.03). Multivariate analysis revealed that treatment-resistant patients had a decreased PFS and overall survival (OS) compared with the treatment-responsive patients (HR 6.45, CI 95 % [2.02-20.64] p = 0.002 and HR 4.64, CI 95 % [1.56-13.79], p = 0.006, respectively). BRCA1 status was associated with neither PFS nor OS. CONCLUSION Combined negative ERCC1 and class III β-tubulin immunostaining is associated with significantly prolonged PFS and OS in MPM patients receiving cisplatin-vinorelbine therapy.

Abstract
Polo-like kinase 4 (PLK4), belonging to serine/threonine kinase family, is critical for centriole replication and cell cycle progression. PLK4 has been proposed as a tumor suppressor in hepatocellular carcinoma (HCC). However, its expression and significance in HCC have not been well studied. In the present study, we found that PLK4 was markedly downregulated in both HCC cell lines and fresh cancer tissues, using quantitative real-time-PCR and western blot. Immunohistochemistry data also revealed that decreased expression of PLK4 was present in 72.4% (178/246) of HCC tissues, compared with the corresponding adjacent nontumorous tissues. Furthermore, PLK4 expression significantly correlated with clinicopathological parameters, including clinical stage (P=0.034), serum α-fetoprotein (AFP) (P=0.019) and tumor size (P=0.032). Moreover, HCC patients with low PLK4 expression survived shorter than those with high PLK4 expression, as indicated by overall survival (P=0.002) and disease-free survival (P=0.012) assessed by the Kaplan-Meier method. In addition, multivariate analysis suggested PLK4 as an independent predictor of overall survival (HR, 0.556; 95%CI, 0.376-0.822; P=0.003) and disease-free survival (HR, 0.547; 95%CI, 0.382-0.783; P=0.001). Collectively, our study demonstrated that PLK4 was remarkably downregulated in HCC and could be served as a potential prognostic marker for patients with this deadly disease.

Improved survival after introduction of chemotherapy for malignant pleural mesothelioma in Slovenia: Population-based survey of 444 patients. Radiol Oncol 2012; 46:136-44. [PMID: 23077450 PMCID: PMC3472938 DOI: 10.2478/v10019-012-0032-0] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2012] [Accepted: 02/10/2012] [Indexed: 12/29/2022] Open
Abstract
Background Malignant pleural mesothelioma is a rare tumour with increasing frequency throughout the world. Due to long latency after exposure to asbestos, restrictions in the production and use of asbestos have not yet alleviated the burden of mesothelioma. During the last decade, several trials confirmed the benefit of systemic treatment with drugs such as doublets with cisplatina and gemcitabine or pemetrexed for carefully selected patients in good performance status. The purpose of this survey was to assess the impact of systemic treatment for the whole national population of patients with mesothelioma. Patients and methods. A retrospective study included all patients in Slovenia with histologically confirmed diagnosis of malignant pleural mesothelioma in the period from 1974 till 2008. Data from the Cancer Registry of Slovenia were supplemented by review of clinical records of the Institute of Oncology in Ljubljana where virtually all non-surgical treatment for mesothelioma was performed. We analysed the incidence, treatment, and survival of patients treated in the era of infrequent chemotherapy (1974–2003, the first period) and after it (2004–2008, the second period). Results The survey included 444 patients, of whom 325 and 119 were diagnosed in the first and second period, respectively. Joinpoint regression analysis showed that after 1995 the trend in crude incidence rates increased more rapidly; the annual change was 0.03 per 100,000 per year before 1995 and 0.06 per 100,000 per year after. There was clear male predominance (70%) throughout the period covered by the survey. The proportion of patients above 65 years of age increased from 41.8% to 54.6% for the first and second period, respectively (p = 0.02). With a total of 52 (11.7%) operated patients, surgical treatment was rare and used only for selected patients with early disease and without comorbidity, leading to their relatively long median survival of 13.6 months. Chemotherapy was applied to 56 (17.2%) and to 96 (80.7%) patients during the first and second period, respectively. While a variety of older drugs were used in the first period, the most common regimen in the second period (applied to 91 patients) was doublet of low-dose gemcitabine in prolonged infusion and cisplatin. For the whole population of patients regardless the mode of treatment, median survival was 7.4 and 12.6 months (p-value = 0.037) for the first and second period, respectively. Conclusions Increasing incidence, male predominance and increased proportion of older patients confirm that the burden of mesothelioma persists in spite of a 15-years old ban in the production of asbestos. Modern chemotherapy, and in particular treatment with low-dose gemcitabine in prolonged infusion and cisplatin significantly prolonged median survival of patients with malignant pleural mesothelioma in Slovenia.
