Abstract
Head and neck cancers are a heterogeneous group of neoplasms, affecting an ever increasing global population. Despite advances in diagnostic technology and surgical approaches to manage these conditions, survival rates have only marginally improved and this has occurred mainly in developed countries. Some improvements in survival, however, have been a result of new management and treatment approaches made possible because of our ever-increasing understanding of the molecular pathways triggered in head and neck oncogenesis, and the growing understanding of the abundant heterogeneity of this group of cancers. Some important pathways are common to other solid tumours, but their impact on reducing the burden of head and neck disease has been less than impressive. Other less known and little-explored pathways may hold the key to the development of potential druggable targets. The extensive work carried out over the last decade, mostly utilising next generation sequencing has opened up the development of many novel approaches to head and neck cancer treatment. This paper explores our current understanding of the molecular pathways of this group of tumours and outlines associated druggable targets which are deployed as therapeutic approaches in head and neck oncology with the ultimate aim of improving patient outcomes and controlling the personal and economic burden of head and neck cancer.

Buckle T, van Alphen M, van Oosterom MN, van Beurden F, Heimburger N, van der Wal JE, van den Brekel M, van Leeuwen FWB, Karakullukcu B. Translation of c-Met Targeted Image-Guided Surgery Solutions in Oral Cavity Cancer-Initial Proof of Concept Data. Cancers (Basel) 2021; 13:cancers13112674. [PMID: 34071623 PMCID: PMC8198422 DOI: 10.3390/cancers13112674] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2021] [Revised: 05/19/2021] [Accepted: 05/27/2021] [Indexed: 12/11/2022] Open
Abstract
Simple Summary Translation of tumor-specific fluorescent tracers is crucial in the realization intraoperative of tumor identification during fluorescence-guided surgery. Ex vivo assessment of surgical specimens after topical tracer application has the potential to reveal the suitability of a potential surgical target prior to in vivo use in patients. In this study, the c-Met receptor was identified as a possible candidate for fluorescence-guided surgery in oral cavity cancer. Freshly excised tumor specimens obtained from ten patients with squamous cell carcinoma of the tongue were incubated with EMI-137 and imaged with a clinical-grade Cy5 prototype fluorescence camera. In total, 9/10 tumors were fluorescently illuminated, while non-visualization could be linked to non-superficial tumor localization. Immunohistochemistry revealed c-Met expression in all ten specimens. Tumor assessment was improved via video representation of the tumor-to-background ratio. Abstract Intraoperative tumor identification (extension/margins/metastases) via receptor-specific targeting is one of the ultimate promises of fluorescence-guided surgery. The translation of fluorescent tracers that enable tumor visualization forms a critical component in the realization of this approach. Ex vivo assessment of surgical specimens after topical tracer application could help provide an intermediate step between preclinical evaluation and first-in-human trials. Here, the suitability of the c-Met receptor as a potential surgical target in oral cavity cancer was explored via topical ex vivo application of the fluorescent tracer EMI-137. Freshly excised tumor specimens obtained from ten patients with squamous cell carcinoma of the tongue were incubated with EMI-137 and imaged with a clinical-grade Cy5 prototype fluorescence camera. In-house developed image processing software allowed video-rate assessment of the tumor-to-background ratio (TBR). Fluorescence imaging results were related to standard pathological evaluation and c-MET immunohistochemistry. After incubation with EMI-137, 9/10 tumors were fluorescently illuminated. Immunohistochemistry revealed c-Met expression in all ten specimens. Non-visualization could be linked to a more deeply situated lesion. Tumor assessment was improved via video representation of the TBR (median TBR: 2.5 (range 1.8–3.1)). Ex vivo evaluation of tumor specimens suggests that c-Met is a possible candidate for fluorescence-guided surgery in oral cavity cancer.

Molecular phenotypes of circulating tumor cells and efficacy of nivolumab treatment in patients with head and neck squamous cell carcinoma. Sci Rep 2020; 10:21573. [PMID: 33299117 PMCID: PMC7726556 DOI: 10.1038/s41598-020-78741-0] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2020] [Accepted: 11/30/2020] [Indexed: 12/14/2022] Open
Abstract
The emergence of immune checkpoint inhibitors (ICIs) has revolutionized the treatment of recurrent/metastatic (R/M) head and neck squamous cell carcinoma (HNSCC). Biomarkers of the therapeutic efficacy of ICIs have been extensively investigated. In this study, we aimed to analyze whether molecular phenotypes of circulating tumor cells (CTCs) are associated with treatment responses and clinical outcomes in patients with R/M HNSCC treated with nivolumab. Peripheral blood samples were collected before treatment initiation and after four infusions of nivolumab. CTCs isolated by depletion of CD45-positive cells were analyzed to determine the expression of EPCAM, MET, KRT19, and EGFR using real-time quantitative polymerase chain reaction. CTC-positive samples were analyzed to determine the expression of PIK3CA, CCND1, SNAI1, VIM, ZEB2, CD44, NANOG, ALDH1A1, CD47, CD274, and PDCD1LG2. Of 30 patients treated with nivolumab, 28 (93.3%) were positive for CTCs. In 20 CTC-positive patients, molecular alterations in CTCs before and after nivolumab treatment were investigated. Patients with MET-positive CTCs had significantly shorter overall survival than those with MET-negative CTCs (p = 0.027). The expression level of CCND1 in CTCs of disease-controlled patients was significantly higher than that of disease-progressed patients (p = 0.034). In disease-controlled patients, the expression level of CCND1 in CTCs significantly decreased after nivolumab treatment (p = 0.043). The NANOG expression in CTCs was significantly increased in disease-controlled patients after nivolumab treatment (p = 0.036). Our findings suggest that the molecular profiling of CTCs is a promising tool to predict the treatment efficacy of nivolumab.

Abstract
Background Both histopathological image features and genomics data were associated with survival outcome of cancer patients. However, integrating features of histopathological images, genomics and other omics for improving prognosis prediction has not been reported in head and neck squamous cell carcinoma (HNSCC). Methods A dataset of 216 HNSCC patients was derived from the Cancer Genome Atlas (TCGA) with information of clinical characteristics, genetic mutation, RNA sequencing, protein expression and histopathological images. Patients were randomly assigned into training (n = 108) or validation (n = 108) sets. We extracted 593 quantitative image features, and used random forest algorithm with 10-fold cross-validation to build prognostic models for overall survival (OS) in training set, then compared the area under the time-dependent receiver operating characteristic curve (AUC) in validation set. Results In validation set, histopathological image features had significant predictive value for OS (5-year AUC = 0.784). The histopathology + omics models showed better predictive performance than genomics, transcriptomics or proteomics alone. Moreover, the multi-omics model incorporating image features, genomics, transcriptomics and proteomics reached the maximal 1-, 3-, and 5-year AUC of 0.871, 0.908, and 0.929, with most significant survival difference (HR = 10.66, 95%CI: 5.06–26.8, p < 0.001). Decision curve analysis also revealed a better net benefit of multi-omics model. Conclusion The histopathological images could provide complementary features to improve prognostic performance for HNSCC patients. The integrative model of histopathological image features and omics data might serve as an effective tool for survival prediction and risk stratification in clinical practice.

Single Nucleotide Polymorphism rs6942067 Is a Risk Factor in Young and in Non-Smoking Patients with HPV Negative Head and Neck Squamous Cell Carcinoma. Cancers (Basel) 2019; 12:cancers12010055.

Abstract
Genetic factors behind the increasing incidence of human papillomavirus (HPV) negative head and neck squamous cell carcinoma (HNSCC) in young non-smokers are suspected, but have not been identified. Recently, rs6942067, a single nucleotide polymorphism (SNP) located upstream of the DCBLD1 gene, was found associated with non-smoking lung adenocarcinoma. To validate if this SNP is also implicated in HNSCC, participants of The Cancer Genome Atlas HNSCC cohort were investigated for rs6942067 status, associated DCBLD1 expression, and clinical characteristics. Occurrence of the rs6942067 GG genotype is significantly higher in young and in HPV negative non-smoking HNSCC than in other HNSCC. Additionally, rs6942067 GG is associated with higher DCBLD1 expression in HNSCC and patients with high DCBLD1 expression have a worse overall survival at three years, both in univariate and multivariate analysis. Furthermore, high DCBLD1 expression is associated with activation of the integrin signaling pathway and its phosphorylation with EGFR and MET. Collectively, these findings suggest that DCBLD1 plays a critical role in HNSCC and demonstrate an association between rs6942067 and clinical characteristics of young age and HPV negative non-smoking status in HNSCC patients.

Abstract
C-Met, also referred to as Hepatocyte Growth Factor Receptor (HGFR), is a heterodimeric
receptor tyrosine kinase. It has been determined that c-Met gene mutations, overexpression, and amplification
also occur in a variety of human tumor types, and these events are closely related to the aberrant
activation of the HGF/c-Met signaling pathway. Meanwhile, high c-Met expression is closely associated
with poor prognosis in cancer patients. The c-Met kinase has emerged as an attractive target for developing
antitumor agents. In this review, we cover the recent advances on the small molecule c-Met inhibitors
discovered from 2018 until now, with a main focus on the rational design, synthesis and structureactivity
relationship analysis.

The Oncogenic Activity of miR-29b-1-5p Induces the Epithelial-Mesenchymal Transition in Oral Squamous Cell Carcinoma. J Clin Med 2019; 8:jcm8020273.

Abstract
Background: The relationship between miR-29b-1-5p and c-Met proto-oncogene in oral squamous cell carcinoma (OSCC) remains to be investigated. This study aimed to reveal the role of miR-29b-1-5p in the pathogenesis of OSCC using molecular and biological analyses. Methods: We investigated the expression of miR-29b-1-5p, c-Met, and markers of the epithelial-mesenchymal transition (EMT) in the tissues of 49 patients with OSCC and in human OSCC cells with different tumorigenicity. Further, we determined the effects of miR-29b-1-5p on the phenotypes of OSCC cell lines. Results: The expression levels of miR-29b-1-5p in most patients with OSCC were higher than those of the normal oral epithelium. In OSCC, upregulation of miR-29b-1-5p significantly correlated with histological grade, the EMT, and the immunohistochemical grade, indicated by c-Met expression. The prognosis was poor for patients with miR-29b-1-5p expression and coexpression of miR-29b-1-5p and c-Met. In OSCC cells exhibiting the EMT phenotype, knockdown of miR-29b-1-5p suppressed the EMT, which was recovered by enforced expression of c-Met. Further, the mRNA encoding cadherin 1 (CDH1) was a direct target of miR-29b-1-5p. Conclusions: Our results suggest that miR-29b-1-5p acts as an oncogenic miRNA that synergizes with c-Met to induce the EMT of OSCC cells.

Abstract
The prognostic role of c-Met expression in patients with head and neck cancer were controversial among different studies. Thus, we performed a meta-analysis to evaluate the relationships between c-Met expression and survival and clinical parameters of head and neck cancer patients. Summary hazard ratio (HR) and 95% confidence intervals (CIs) were calculated to analyze the correlations between c-Met expression and overall survival (OS), and disease-free survival (DFS). Furthermore, odds ratios (ORs) and 95% CIs were used to describe the relationships between c-Met expression and different clinicopathological parameters. A total of 2417 patients from 19 studies were enrolled in the final analysis. The results showed that patients with higher c-Met expression had a poor OS (HR, 1.65; 95% CI, 1.20-2.27) and DFS (HR, 1.48; 95% CI, 0.99-2.20). In addition, c-Met expression was associated with the N classification of patients with head and neck cancer. These results suggested that c-Met expression was a risk factor for head and neck cancer, and increased c-Met expression would be a predictor of a poorer prognosis for the patients.

Abstract
Head and neck squamous cell carcinoma (HNSCC) is the sixth most common malignancy worldwide, accounting for more than 550,000 cases and 380,000 deaths annually. The primary risk factors associated with HNSCC are tobacco use and alcohol consumption; nevertheless genetic predisposition and oncogenic viruses also play important roles in the development of these malignancies. The current treatments for HNSCC patients include surgery, chemotherapy, radiotherapy, and cetuximab, and combinations of these. However, these treatments are associated with significant toxicity, and many patients are either refractory to the treatment or relapse after a short period. Despite improvements in the treatment of patients with HNSCC, the clinical outcomes of those who have been treated with standard therapies have remained unchanged for over three decades and the 5-year overall survival rate in these patients remains around 40-50%. Therefore, more specific and less toxic therapies are needed in order to improve patient outcomes. The tumour microenvironment of HNSCC is immunosuppressive; therefore immunotherapy strategies that can overcome the immunosuppressive environment and produce long-term tumour immunosurveillance will have a significant therapeutic impact in these patients. This review focuses on the current immunological treatment options under investigation or available for clinical use in patients with HNSCC.

Abstract
This meta-analysis aims to evaluate the effects of high c-Met levels in head and neck squamous cell carcinomas (HNSCC) on survival and clinicopathological features. Publications concerned with the clinical significance of c-Met protein expression in HNSCC were identified from the Scopus and Web of Science database searches. To elucidate the relationship between c-Met expression and clinical outcomes, a meta-analysis of the selected articles was conducted. Seventeen publications involving a total of 1724 patients met the inclusion criteria. c-Met overexpression was significantly correlated with poor overall survival (hazard ratio (HR) = 2.19, 95% confidence interval (CI) = 1.55-3.10). c-Met immunohistochemical staining positivity was also associated with worse relapse-free survival (HR = 1.64, 95% CI = 1.24-2.17) and presence of regional lymph node metastases (odds ratio (OR) = 1.76, 95% CI = 1.26-2.45). High levels of c-Met expression in HNSCC predict unfavorable prognosis associated with common clinicopathological features.

Identification of MET exon14 skipping by targeted DNA- and RNA-based next-generation sequencing in pulmonary sarcomatoid carcinomas. Lung Cancer 2018; 122:113-119. [PMID: 30032818 DOI: 10.1016/j.lungcan.2018.06.001] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2018] [Revised: 05/22/2018] [Accepted: 06/01/2018] [Indexed: 11/20/2022]
Abstract
BACKGROUND Pulmonary sarcomatoid carcinomas (PSCs) constitutes a heterogeneous group of NSCLCs, which show poor prognosis even with aggressive surgical treatment and postoperative chemotherapy. The detection MET exon14 skipping (METex14 skipping) in PSCs suggests the targeted therapeutic opportunities with MET TKIs. PATIENTS AND METHODS We detected MET exon14 alterations using both targeted DNA- and RNA-based Next Generation Sequencing (NGS) and elucidated the driver mutation profile of 77 Chinese PSC patients. We also collected and analyzed the demographic features and clinical outcomes of patients harboring METex14 skipping mutation. RESULTS METex14 skipping was detected in 20.8% of PSCs. A concordance of 96.1% was observed for DNA- and RNA-based NGS. 13 different genomic variants were revealed to induce METex14 skipping, including indels (N = 1) at splice acceptor sites, base substitutions (N = 4) and indels (N = 5) at splice donor sites, indels (N = 2) in the ∼20bp intronic noncoding region adjacent to the splice acceptor site, and indels (N = 1) in the exonic region. Patients harboring METex14 skipping tended to be older than others. In most cases, METex14 skipping were exclusive to other tumor driver alterations, however, we detected one case with METex14 skipping and a concurrent KRAS mutation. In survival analysis, we identified METex14 skipping as an unfavorable factor for Disease Free Survival (DFS) of PSCs. CONCLUSION Although a high concordance of 96.1% was observed for DNA- and RNA-based NGS in detecting METex14 skipping, RNA-based sequencing appears the most accurate method, because some somatic variants not covering METex14 splices sites might also induce skipping. Without targeted treatment, patients with METex14 skipping had a shorter DFS. Because of the clinical significance of METex14 skipping and emerging effective treatment with MET TKI, the clinical screening for METex14 skipping should be encouraged, particularly in PSC patients who have poor prognosis with no effective treatments.

Abstract
High c-Met expression has been observed in head and neck squamous cell carcinoma (HNSCC). However, its clinicopathological impact remains controversial. We performed this meta-analysis to evaluate the pathologic and prognostic impacts of c-Met overexpression in patients with HNSCC. A systematic computerized search of the electronic databases was carried out. From 16 studies, 1,948 patients with HNSCC were included in the meta-analysis. Compared with HNSCCs showing low c-Met expression, tumors with high c-Met expression were significantly associated with higher rate of lymph node metastasis (odds ratio = 3.26, 95% CI: 2.27–4.69, P < 0.00001) and higher T stage (odds ratio = 1.33, 95% CI: 1.03–1.71, P = 0.03). In addition, patients with c-Met-high HNSCC showed significantly worse disease-free survival (hazard ratio = 1.49, 95% CI: 1.04–2.14, P = 0.03) and overall survival (hazard ratio = 1.83, 95% CI: 1.29–2.60, P = 0.0007) than those with c-Met-low tumor. In conclusion, this meta-analysis demonstrates that high c-Met expression is significantly associated with worse pathological features and prognosis, indicating c-Met overexpression is an adverse prognostic marker for patients with HNSCC.

Prognostic value of c-MET in head and neck cancer: A systematic review and meta-analysis of aggregate data. Oral Oncol 2017; 74:68-76.

Abstract
OBJECTIVES The hepatocyte growth factor (HGF)/mesenchymal-epithelial transition factor (c-MET) ligand/receptor axis has been implicated in pathogenesis of malignant diseases including squamous cell carcinoma of the head and neck (SCCHN). Overexpression of c-MET has been reported as a common molecular abnormality in SCCHN, although its prognostic and predictive value remains to be validated. METHODS We systematically searched literature for studies evaluating c-MET expression on immunohistochemistry in newly diagnosed, non-metastatic SCCHN. The c-MET expressing cases were classified into three categories according to predefined cut-off values for positivity. Our aim was to assess the prevalence of c-MET expression and its relationship with selected clinicopathological variables. RESULTS Twenty-eight studies with 2019 cases were included. Relative frequencies of c-MET expression above cut-off levels I, II, and III were 81.8%, 63.8%, and 46.2%, respectively. Differences between these three values were statistically significant (p<1.0×10-6). Above cut-off level II, c-MET positivity was associated with worse overall survival (p=4.0×10-6), positive nodal status (p=1.0×10-4), higher disease stage (p=7.0×10-4), older age (p=2.1×10-3), disease recurrence (p=2.0×10-2), and primary tumour localization in the oral cavity (p=2.3×10-2). Above cut-off level III, c-MET positivity was associated with worse disease-free or progression-free survival (p=9.0×10-6), p16 negativity (p=2.4×10-4), worse overall survival (p=4.0×10-4), positive epidermal growth factor receptor (EGFR) status (p=7.2×10-4), and larger primary tumours (p=4.6×10-3). CONCLUSION In SCCHN, immunohistochemical overexpression of c-MET above cut-off levels III and particularly II was associated with inferior survival outcomes and advanced disease. Moreover, it represents a promising predictive biomarker for c-MET targeting, yet the optimal scoring method remains to be defined.

Abstract
Aberrant signaling of the hepatocyte growth factor (HGF)/c-Met pathway has been identified as a promoter of tumorigenesis in several tumor types including head and neck squamous cell carcinoma (HNSCC). Despite a relatively low c-Met mutation frequency, overexpression of HGF and its receptor c-Met has been observed in more than 80% of HNSCC tumors, with preclinical and clinical studies linking overexpression with cellular proliferation, invasion, migration, and poor prognosis. c-Met is activated by HGF through a paracrine mechanism to promote cellular morphogenesis enabling cells to acquire mesenchymal phenotypes in part through the epithelial-mesenchymal transition, contributing to metastasis. The HGF/c-Met pathway may also act as a resistance mechanism against epidermal growth factor receptor (EGFR) inhibition in advanced HNSCC. Furthermore, with the identification of a biologically distinct subset of HNSCC tumors acquired from human papillomavirus (HPV) infection that generally portends a good prognosis, high expression of HGF or c-Met in HPV-negative tumors has been associated with worse prognosis. Dysregulated HGF/c-Met signaling results in an aggressive HNSCC phenotype which has led to clinical investigations for targeted inhibition of this pathway. In this review, HGF/c-Met signaling, pathway alterations, associations with clinical outcomes, and preclinical and clinical therapeutic strategies for targeting HGF/c-Met signaling in HNSCC are discussed.

Abstract
INTRODUCTION Recurrent somatic splice-site alterations at MET exon 14 (METΔ14), which result in exon skipping and MET proto-oncogene, receptor tyrosine kinase (MET) activation, have been characterised. However, their demographic features and clinical outcomes in East Asian lung cancer patients have yet to be determined. METHODS A one-step reverse transcription-polymerase chain reaction (RT-PCR), using RNA samples from 850 East Asian lung cancer patients, was performed in order to detect METΔ14 and five other major driver mutations, including those in the EGFR, KRAS, ALK, HER2, and ROS1 genes. Immunohistochemistry (IHC) was used to confirm the overexpression of MET in patients harbouring the METΔ14 mutation. We analysed the demographic data and clinical outcomes of METΔ14 mutation positive lung cancer patients and compared them to those of METΔ14 mutation negative lung cancer patients. RESULTS In total, 27 lung adenocarcinoma (ADC) patients and 1 squamous cell carcinoma patient with the METΔ14 mutation were identified. The overall incidence was 3.3% for lung cancer and 4.0% for lung ADC. IHC demonstrated that the majority of lung cancer patients harboring a METΔ14 mutation exhibited a strong cytoplasmic expression of MET. METΔ14 mutation positive patients were generally quite elderly individuals. Stage IV METΔ14 mutation positive lung cancer patients receiving no specific anti-MET therapy were observed to have a similar overall survival (OS) compared to patients in the all negative group (P>0.05). In the multivariate analysis, mutation status was found not to be a major risk factor for OS in lung cancer patients without appropriate tyrosine kinase inhibitors treatment. CONCLUSIONS The OS of METΔ14 mutation positive lung cancer patients is comparable to that of the major driver gene mutation negative lung cancer patients.

Abstract
The MET pathway plays a key role in various cancers, and its inhibition represents a potential treatment target. However, appropriate biomarkers are needed to facilitate the selection of patients who would benefit from MET inhibiting therapy. We herein conducted a robust confirmatory evaluation of the MET copy number alteration status and prognostic significance of c-Met expression in a large series of patients (n = 396) who underwent standard surgical resection and adjuvant chemoradiotherapy for head and neck squamous cell carcinoma (HNSCC). Surgically resected HNSCC samples were subjected to immunohistochemical and H-score analysis of c-Met expression and silver in situ hybridization analysis of MET amplification and copy number gains. c-Met expression varied, with mean and median H-scores (scale: 0-300 scale) of 61.2 and 60.0, respectively. The lowest and highest expression levels were observed in SCC of the larynx and oral cavity, respectively. MET copy number gains were observed in 16.9% of cases (67/339) and were associated with c-Met protein expression. High c-Met expression, determined according to MET gain status, was associated with an inferior overall survival rate, especially among completely resected cases. In conclusion, our robust analysis revealed that c-Met expression in HNSCCs varied according to anatomical site, correlated with MET copy number gains, and was associated with poor prognosis. This c-Met expression analysis method, which is based on the MET gain status, appears to appropriately predict high-risk HNSCC patients in the context of anti-MET therapeutic decisions.

Abstract
IMPORTANCE Ficlatuzumab can be used to treat head and neck squamous cell carcinoma (HNSCC) by inhibiting c-Met receptor-mediated cell proliferation, migration, and invasion. OBJECTIVE To understand the effect of ficlatuzumab on HNSCC proliferation, migration, and invasion. DESIGN, SETTING, AND PARTICIPANTS The effects of ficlatuzumab on HNSCC proliferation, invasion, and migration were tested. Mitigation of c-Met and downstream signaling was assessed by immunoblotting. The tumor microenvironment has emerged as an important factor in HNSCC tumor progression. The most abundant stromal cells in HNSCC tumor microenvironment are tumor-associated fibroblasts (TAFs). We previously reported that TAFs facilitate HNSCC growth and metastasis. Furthermore, activation of the c-Met tyrosine kinase receptor by TAF-secreted hepatocyte growth factor (HGF) facilitates tumor invasion. Ficlatuzumab is a humanized monoclonal antibody that sequesters HGF, preventing it from binding to and activating c-Met. We hypothesized that targeting the c-Met pathway with ficlatuzumab will mitigate TAF-mediated HNSCC proliferation, migration, and invasion. Representative HNSCC cell lines HN5, UM-SCC-1, and OSC-19 were used in these studies. EXPOSURES FOR OBSERVATIONAL STUDIES The HNSCC cell lines were treated with ficlatuzumab, 0 to 100 µg/mL, for 24 to 72 hours. MAIN OUTCOMES AND MEASURES Ficlatuzumab inhibited HNSCC progression through c-Met and mitogen-activated protein kinase (MAPK) signaling pathway. RESULTS Ficlatuzumab significantly reduced TAF-facilitated HNSCC cell proliferation (HN5, P < .001; UM-SCC-1, P < .001), migration (HN5, P = .002; UM-SCC-1, P = .01; and OSC-19, P = .04), and invasion (HN5, P = .047; UM-SCC-1, P = .03; and OSC-19, P = .04) through a 3-dimensional peptide-based hydrogel (PGmatrix). In addition, ficlatuzumab also inhibited the phosphorylation of c-Met at Tyr1234/1235 and p44/42 MAPK in HNSCC cells exposed to recombinant HGF. CONCLUSIONS AND RELEVANCE We demonstrate that neutralizing TAF-derived HGF with ficlatuzumab effectively mitigates c-Met signaling and decreases HNSCC proliferation, migration, and invasion. Thus, ficlatuzumab effectively mitigates stromal influences on HNSCC progression.

Abstract
OBJECTIVES (1) Reanalyze publicly available genomic data for HPV-negative oral cavity squamous cell carcinoma to look for candidate biomarkers. (2) Evaluate the association of the identified biomarkers with survival. STUDY DESIGN Retrospective cohort study. SETTING Tertiary care. SUBJECTS AND METHODS Gene expression barcode analysis was applied to an existing publicly available data set of 54 HPV-negative oral cavity squamous cell carcinoma tumor samples to identify candidate genes associated with poor prognosis. Genes identified were evaluated for their association with survival on the basis of univariable and multivariable Cox proportional hazards models. RESULTS Three genes were found to be associated with poor prognosis. The most significant association was seen with spectrin expression. Subjects whose tumors expressed spectrin were 4.60 times more likely (hazard ratio; 95% confidence interval: 1.88-11.25) to die at any given time when compared with those without spectrin (P = .001). On univariable analysis, subjects with late-stage cancer were 6.34 times more likely (hazard ratio; 95% confidence interval: 1.41-28.53; P = .02) to die at any given time, but interestingly, after controlling for spectrin, this effect was attenuated (P = .07). Despite controlling for several possible confounding effects, the effect of spectrin remained hazardous throughout all multivariable models. This was true even after controlling for cancer stage and extracapsular extension (P = .004). CONCLUSION Our analysis of public genomic data shows promise in identifying biomarkers that may allow clinicians to make more accurate survival predictions. Spectrin is a strong candidate for further biomarker testing.

Abstract
OBJECTIVES Epidermal growth factor receptor (EGFR)-targeted therapy is frequently used in the treatment of advanced head and neck squamous cell carcinoma (HNSCC). However, constitutive or acquired resistance is common and underlying resistance mechanisms remain poorly understood. We investigated the expression levels of growth factors (GF) in tumor-associated stroma and tumor from HNSCC patients and determined the influence of GFs on EGFR inhibitor efficacy in vitro. MATERIALS AND METHODS The Chicago HNC Genomic Cohort (CHGC) was queried for GF and receptor tyrosine kinase (RTK) expression. Viability assays were used to evaluate the effect of EGFR inhibition (gefitinib), GF treatment, or both in HNSCC cell lines. Caspase-based assays were used to measure apoptotic activity. Expression of RTKs was determined and correlated with GF treatment effects. RESULTS Amphiregulin (AREG), transforming growth factor (TGFβ1), insulin like growth factor (IGF1), fibroblast growth factors (FGF1/FGF2) and the corresponding RTKs were highly expressed in 30-50% of HNSCC, and expression was usually concurrent. While EGFR inhibition was markedly efficacious in HNC cell lines (HN5/HN13/H400/SCC61), co-treatment with most GFs increased viability up to 100%. Only TGFβ1 treatment was additive to EGFR inhibition. GFs also reduced apoptotic effects of EGFR inhibition. RTK expression showed strong positive correlation with respective GF treatment effect for IGF1-IGF1R, less strong for HGF-MET/AREG-EGFR and a moderate negative correlation for TGFβ1-TGFBR1/2. CONCLUSION High expression of GFs/RTKs occurs in HNSCC. Co-expression is common. GF expression contributes to EGFR inhibition resistance in our model system, and may be a common mechanism of constitutive or acquired resistance to EGFR inhibition in HNSCC.

Abstract
Based on currently available genomic data, most head and neck squamous cell carcinoma have few targetable aberrations and immediate clinical translation is challenging. However, potential therapeutic agents listed in this article need to be thoroughly evaluated because there are compelling scientific rationales supporting their development. Concerted effort is required to identify better predictive biomarkers of clinical benefit and improve the therapeutic index. Clinicians need to better understand resistance mechanisms, generate novel hypotheses for appropriate combination regimens and dosing schedules, develop more accurate model systems, and conduct innovative clinical trials.

Abstract
BACKGROUND Mesenchymal-epithelial transition (MET) is an oncogene encoding for a trans-membrane tyrosine kinase receptor activated by the hepatocyte growth factor (HGF). MET has a normal function in organ development during embryogenesis and in tissue homeostasis during adult life. Deregulation of HGF/MET signaling pathway is frequently observed in many cancer types, conferring invasive growth and tendency to progression. MET deregulation is due to gene amplification or increased copy number, gene mutation, receptor over-expression or ligand autocrine loops activation. These events lead to migration, invasion, proliferation, metastatic spread and neo-angiogenesis of cancer cells, suggesting that anti-HGF/MET agents may represent a potential antitumor strategy. In breast cancer (BC), preclinical and clinical data demonstrated the role of HGF/MET signalling pathway in carcinogenesis, disease progression and resistance features. METHODS For this review article, all published data on HGF/MET in BC were collected and analyzed. RESULTS Several evidences underline that, in early BC, MET over-expression has an independent negative prognostic significance, regardless of method used for evaluation and BC subtypes. Available data suggest that MET is a relevant target particularly in basal-like (BL) and in triple negative BC. Moreover, preclinical and retrospective data support the critical role of MET deregulation in the development of resistance to target-agents, such as anti-HER2 strategies. CONCLUSIONS MET is a promising new target in BC. Several anti-MET agents are under investigation and ongoing clinical trials will clarify its relevance in BC treatment.

Abstract
A series of 4-(2-fluorophenoxy)quinoline derivatives containing an imidazolone moiety were designed, synthesized and evaluated for their in vitro biological activities against c-Met kinase and four cancer cell lines (A549, H460, HT-29 and MKN-45). Most compounds showed moderate to excellent activities in enzyme and cellular assays. The most promising analog, 58 (c-Met IC50=1.42 nM), displayed 2.1-, 8.6-fold increase against H460, and MKN-45 cell lines, respectively, compared with foretinib. An analysis of structure-activity relationships revealed that an ortho substituted phenyl ring as well as an N-unsubstituted imidazolone linker is favorable for antitumor activity.

Abstract
Background c-Met is widely known as a poor prognostic factor in various human malignancies. Previous studies have suggested the involvement of c-Met and/or its ligand, hepatocyte growth factor (HGF), in esophageal squamous cell carcinoma (ESCC), but the correlation between c-Met status and clinical outcome remains unclear. Furthermore, the identification of a novel molecular therapeutic target might potentially help improve the clinical outcome of ESCC patients. Methods The expression of c-Met and HGF was immunohistochemically assessed in 104 surgically obtained tissue specimens. The correlation between c-Met/HGF expression and patients’ clinicopathological features, including survival, was evaluated. We also investigated changes in cell functions and protein expression of c-Met and its downstream signaling pathway components under treatments with HGF and/or c-Met inhibitor in ESCC cell lines. Results Elevated expression of c-Met was significantly correlated with tumor depth and pathological stage. Patients with high c-Met expression had significantly worse survival. In addition, multivariate analysis identified the high expression of c-Met as an independent prognostic factor. Treatment with c-Met inhibitor under HGF stimulation significantly inhibited the invasive capacity of an ESCC cell line with elevated c-Met mRNA expression. Moreover, c-Met and its downstream signaling inactivation was also detected after treatment with c-Met inhibitor. Conclusions The results of our study identified c-Met expression as an independent prognostic factor in ESCC patients and demonstrated that c-Met could be a potential molecular therapeutic target for the treatment of ESCC with elevated c-Met expression.

Abstract
Lung cancer is the number one cause of cancer related mortality with over 1 million cancer deaths worldwide. Numerous therapies have been developed for the treatment of lung cancer including radiation, cytotoxic chemotherapy and targeted therapies. Histology, stage of presentation and molecular aberrations are main determinants of prognosis and treatment strategy. Despite the advances that have been made, overall prognosis for lung cancer patients remains dismal. Chemotherapy and/or targeted therapy yield objective response rates of about 35% to 60% in advanced stage non-small cell lung cancer (NSCLC). Even with good initial responses, median overall survival of is limited to about 12 months. This reflects that current therapies are not universally effective and resistance develops quickly. Multiple mechanisms of resistance have been proposed and the MET/HGF axis is a potential key contributor. The proto-oncogene MET (mesenchymal-epithelial transition factor gene) and its ligand hepatocyte growth factor (HGF) interact and activate downstream signaling via the mitogen-activated protein kinase (ERK/MAPK) pathway and the phosphatidylinositol 3-kinase (PI3K/AKT) pathways that regulate gene expression that promotes carcinogenesis. Aberrant MET/HGF signaling promotes emergence of an oncogenic phenotype by promoting cellular proliferation, survival, migration, invasion and angiogenesis. The MET/HGF axis has been implicated in various tumor types including lung cancers and is associated with adverse clinicopathological profile and poor outcomes. The MET/HGF axis plays a major role in development of radioresistance and chemoresistance to platinums, taxanes, camtothecins and anthracyclines by inhibiting apoptosis via activation of PI3K-AKT pathway. DNA damage from these agents induces MET and/or HGF expression. Another resistance mechanism is inhibition of chemoradiation induced translocation of apoptosis-inducing factor (AIF) thereby preventing apoptosis. Furthermore, this MET/HGF axis interacts with other oncogenic signaling pathways such as the epidermal growth factor receptor (EGFR) pathway and the vascular endothelial growth factor receptor (VEGFR) pathway. This functional cross-talk forms the basis for the role of MET/HGF axis in resistance against anti-EGFR and anti-VEGF targeted therapies. MET and/or HGF overexpression from gene amplification and activation are mechanisms of resistance to cetuximab and EGFR-TKIs. VEGF inhibition promotes hypoxia induced transcriptional activation of MET proto-oncogene that promotes angiogenesis and confers resistance to anti-angiogenic therapy. An extensive understanding of these resistance mechanisms is essential to design combinations with enhanced cytotoxic effects. Lung cancer treatment is challenging. Current therapies have limited efficacy due to primary and acquired resistance. The MET/HGF axis plays a key role in development of this resistance. Combining MET/HGF inhibitors with chemotherapy, radiotherapy and targeted therapy holds promise for improving outcomes.

Abstract
Small-cell lung cancer (SCLC) is one of the most aggressive lung tumors. The majority of patients with SCLC are diagnosed at an advanced stage. This tumor type is highly sensitive to chemo-radiation treatment, with very high response rates, but invariably relapses. At this time, treatment options are still limited and the prognosis of these patients is poor. A better knowledge of the molecular biology of SCLC allowed us to identify potential druggable targets. Among these, the MET/HGF axis seems to be one of the most aberrant signaling pathways involved in SCLC invasiveness and progression. In this review, we describe briefly all recent literature on the different molecular profiling in SCLC; in particular, we discuss the specific alterations involving c-MET gene and their implications as a potential target in SCLC.

c-Met expression is a marker of poor prognosis in patients with locally advanced head and neck squamous cell carcinoma treated with chemoradiation. Int J Radiat Oncol Biol Phys 2014; 88:701-7.

Abstract
PURPOSE To examine the prognostic significance of c-Met expression in relation to p16 and epidermal growth factor receptor (EGFR) in patients with locally advanced head and neck squamous cell carcinoma (HNSCC) treated with definitive concurrent chemoradiation. METHODS AND MATERIALS Archival tissue from 107 HNSCC patients treated with chemoradiation was retrieved, and a tissue microarray was assembled. Immunohistochemical staining of c-Met, p16, and EGFR was performed. c-Met expression was correlated with p16, EGFR, clinical characteristics, and clinical endpoints including locoregional control (LRC), distant metastasis (DM), disease-free survival (DFS), and overall survival (OS). RESULTS Fifty-one percent of patients were positive for p16, and 53% were positive for EGFR. Both p16-negative (P≤.001) and EGFR-positive (P=.019) status predicted for worse DFS. Ninety-three percent of patients stained positive for c-Met. Patients were divided into low (0, 1, or 2+ intensity) or high (3+ intensity) c-Met expression. On univariate analysis, high c-Met expression predicted for worse LRC (hazard ratio [HR] 2.27; 95% CI, 1.08-4.77; P=.031), DM (HR 4.41; 95% CI, 1.56-12.45; P=.005), DFS (HR 3.00; 95% CI, 1.68-5.38; P<.001), and OS (HR 4.35; 95% CI, 2.13-8.88; P<.001). On multivariate analysis, after adjustment for site, T stage, smoking history, and EGFR status, only high c-Met expression (P=.011) and negative p16 status (P=.003) predicted for worse DFS. High c-Met expression was predictive of worse DFS in both EGFR-positive (P=.032) and -negative (P=.008) patients. In the p16-negative patients, those with high c-Met expression had worse DFS (P=.036) than did those with low c-Met expression. c-Met expression was not associated with any outcome in the p16-positive patients. CONCLUSIONS c-Met is expressed in the majority of locally advanced HNSCC cases, and high c-Met expression predicts for worse clinical outcomes. High c-Met expression predicted for worse DFS in p16-negative patients but not in p16-positive patients. c-Met predicted for worse outcome regardless of EGFR status.

Abstract
Head and neck cancers encompass a heterogeneous group of tumours that, in general, are biologically aggressive in nature. These cancers remain difficult to treat and treatment can cause severe, long-term side effects. For patients who are not cured by surgery and/or (chemo)radiotherapy, there are few effective treatment options. Targeted therapies and predictive biomarkers are urgently needed in order to improve the management and minimise the treatment toxicity, and to allow selection of patients who are likely to benefit from both nonselective and targeted therapies. This clinical update aims to provide an insight into the current understanding of the molecular pathogenesis of the disease, and explores the novel therapies under development and in clinical trials.

Abstract
Background Identification of MET genetic alteration, mutation, or amplification in oropharyngeal squamous cell carcinoma (OPSCC) could lead to development of MET selective kinase inhibitors. The aim of this study was to assess the frequency and prognostic value of MET gene mutation, amplification, and protein expression in primary OPSCC. Methods A retrospective chart review was conducted of patients treated for single primary OPSCC between January 2007 and December 2009. Pre-treatment OPSCC tissue samples were analyzed for MET mutations, gene amplification, and overexpression using Sanger sequencing, FISH analysis, and immunohistochemistry respectively. Univariate and multivariate analyses were used to analyze correlations between molecular abnormalities and patient survival. Results 143 patients were included in this study. Six cases (4%) were identified that had a genetic variation, but previously described mutations such as p.Tyr1235Asp (Y1235D) or p.Tyr1230Cys (Y1230C) were not detected. There were 15 high polysomy cases, and only 3 cases met the criteria for true MET amplification, with ≥10% amplified cells per case. Immunohistochemistry evaluation showed 43% of cases were c-MET negative and in 57% c-MET was observed at the tumor cell level. Multivariate analysis showed no significant association between MET mutation, amplification, or expression and survival. Conclusions Our study shows a low frequency of MET mutations and amplification in this cohort of OPSCC. There was no significant correlation between MET mutations, amplification, or expression and patient survival. These results suggest that patient selection based on these MET genetic abnormalities may not be a reliable strategy for therapeutic intervention in OPSCC.

Silencing Met receptor tyrosine kinase signaling decreased oral tumor growth and increased survival of nude mice. Oral Oncol 2013; 50:104-12.

Abstract
OBJECTIVES The hepatocyte growth factor receptor (Met) is frequently overexpressed in Head and Neck Squamous Cell Carcinoma (HNSCC), correlating positively with high-grade tumors and shortened patient survival. As such, Met may represent an important therapeutic target. The purpose of this study was to explore the role of Met signaling for HNSCC growth and locoregional dissemination. MATERIALS AND METHODS Using a lentiviral system for RNA interference, we knocked down Met in established HNSCC cell lines that express high levels of the endogenous receptor. The effect of Met silencing on in vitro proliferation, cell survival and migration was examined using western analysis, immunohistochemistry and live cell imaging. In vivo tumor growth, dissemination and mouse survival was assessed using an orthotopic tongue mouse model for HNSCC. RESULTS We show that Met knockdown (1) impaired activation of downstream MAPK signaling; (2) reduced cell viability and anchorage independent growth; (3) abrogated HGF-induced cell motility on laminin; (4) reduced in vivo tumor growth by increased cell apoptosis; (5) caused reduced incidence of tumor dissemination to regional lymph nodes and (6) increased the survival of nude mice with orthotopic xenografts. CONCLUSION Met signaling is important for HNSCC growth and locoregional dissemination in vivo and that targeting Met may be an important strategy for therapy.

Abstract
Cancers of the head and neck that arise from habitual exposure to carcinogens have lower cure rates than those that arise from infection with human papillomavirus (HPV), and intensification of cytotoxic chemotherapy and radiation has not improved outcomes. HPV-negative head and neck cancers abundantly express EGFR, and the monoclonal antibody cetuximab, directed against EGFR, is the only targeted therapy that has improved disease survival so far. However, response rates to single-agent cetuximab are lower than 15%, and cetuximab given with chemotherapy or radiation leads to only a modest effect on survival. Thus, investigating the mechanisms of resistance to EGFR inhibition in HPV-negative head and neck cancer might help identify novel and active therapies. In this Review, we focus on therapies in development that target redundant receptor tyrosine kinases (eg, HER2 and MET), reduce or abrogate nuclear functions of EGFR, affect cellular trafficking by inhibition of histone deacetylase, or treatments that might address resistance that arises in the EGFR signalling stream (eg, aurora-kinase inhibitors and STAT decoys).

Abstract
Head and neck squamous cell carcinoma (HNSCC) is a common malignancy that continues to be difficult to treat and cure. In many organ systems and tumor types, there have been significant advances in the understanding of the molecular basis for tumorigenesis, disease progression and genetic implications for therapeutics. Although tumorigenesis pathways and the molecular etiologies of HNSCC have been extensively studied, there are still very few diagnostic clinical applications used in practice today. This review discusses current clinically applicable molecular markers, including viral detection of Epstein-Barr virus and human papillomavirus, and molecular targets that are used in diagnosis and management of HNSCC. The common oncogenes EGFR, RAS, CCND1, BRAF, and PIK3CA and tumor suppressor genes p53, CDKN2A and NOTCH are discussed for their associations with HNSCC. Discussion of markers with potential future applications is also included, with a focus on molecular alterations associated with targeted therapy resistance.

Abstract
Clear cell adenocarcinoma of the ovary (OCC) is a chemo-resistant tumor with a relatively poor prognosis and is frequently associated with endometriosis. Although it is assumed that oxidative stress plays some role in the malignant transformation of this tumor, the characteristic molecular events leading to carcinogenesis remain unknown. In this study, an array-based comparative genomic hybridization (CGH) analysis revealed Met gene amplification in 4/13 OCC primary tumors and 2/8 OCC cell lines. Amplification of the AKT2 gene, which is a downstream component of the Met/PI3K signaling pathway, was also observed in 5/21 samples by array-based CGH analysis. In one patient, both the Met and AKT2 genes were amplified. These findings were confirmed using fluorescence in situ hybridization, real-time quantitative PCR, immunoblotting, and immunohistochemistry. In total, 73 OCC cases were evaluated using real-time quantitative PCR; 37.0% demonstrated Met gene amplification (>4 copies), and 8.2% had AKT2 amplification. Furthermore, stage 1 and 2 patients with Met gene amplification had significantly worse survival than patients without Met gene amplification (p<0.05). Met knockdown by shRNA resulted in reduced viability of OCC cells with Met amplification due to increased apoptosis and cellular senescence, suggesting that the Met signaling pathway plays an important role in OCC carcinogenesis. Thus, we believe that targeted inhibition of the Met pathway may be a promising treatment for OCC.

Abstract
Background Activation of the c-Met pathway is involved in cancer progression and the prognosis. We aimed to identify any association of c-Met protein expression with a number of clinicopathologic variables including infection of human papillomavirus and Epstein-Barr virus (EBV) in head and neck carcinomas (HNCa). Methods Eighty-two cases were enrolled in this study. Expression of c-Met and p16 was investigated immunohistochemically. EBV was detected by in situ hybridization and amplification of the c-Met gene by fluorescence in situ hybridization. Results The c-Met protein was expressed in 41.5% (34/82), and gene amplification was found in 1.4% (1/71). High expression of c-Met was associated with the primary location of the tumor; the hypopharynx showed the highest expression, followed by the oral cavity, larynx, and nasal cavity. Squamous cell carcinoma expressed c-Met more frequently than undifferentiated carcinoma. Also, p16 immunoreactivity or EBV infection was associated with the tumor location and well-differentiated histologic type, but were not linked to c-Met expression. The patients with positive c-Met expression showed frequent lymph node metastasis. Conclusions Activation of the c-Met pathway might be involved in a subset of HNCa. Cases showing positive c-Met expression should be carefully monitored because of the high probability of lymph node metastasis.

Abstract
SUMMARY Metastatic non-small-cell lung cancer (NSCLC) is one of the most incident cancers for which no curative therapies exist. New insights into the genetic background of the disease have led to the development of new effective therapies, including monoclonal antibodies. Bevacizumab demonstrated improved response rate and progression-free survival in two Phase III trials in association with conventional chemotherapy as first-line treatment for metastatic NSCLC. Cetuximab has proved to be effective in patients with advanced NSCLC expressing EGFR by immunohistochemistry. One of the promising targets in NSCLC is the MET pathway, for which monoclonal antibodies are under development. This review aims to describe the role of monoclonal antibodies for advanced NSCLC and future perspectives in this field.

Abstract
SUMMARY Colorectal cancer (CRC) accounts for 10% of all cancer-related mortality globally. Despite significant therapeutic advances, overall survival is limited. The restricted repertoire of therapies necessitates investigation into novel pathways of colorectal carcinogenesis. The proto-oncogene MET encodes a receptor tyrosine kinase that acts as a receptor for the HGF. Dysregulation of this MET–HGF axis has been implicated in proliferation, survival and metastasis in various tumor types including CRC. Increased MET–HGF expression correlates with tumor progression and adverse survival outcome. The prognostic impact argues in favor of employing inhibition of the MET–HGF axis as a promising new therapeutic strategy. Future investigations should endeavor to assess the potential application of targeted MET–HGF therapy in CRC and towards patient selection.

Abstract
The MET pathway is dysregulated in many human cancers and promotes tumour growth, invasion and dissemination. Abnormalities in MET signalling have been reported to correlate with poor clinical outcomes and drug resistance in patients with cancer. Thus, MET has emerged as an attractive target for cancer therapy. Several MET inhibitors have been introduced into the clinic, and are currently in all phases of clinical trials. In general, initial results from these studies indicate only a modest benefit in unselected populations. In this Review, we discuss current challenges in developing MET inhibitors--including identification of predictive biomarkers--as well as the most-efficient ways to combine these drugs with other targeted agents or with classic chemotherapy or radiotherapy.

Abstract
BACKGROUND The aim of this study was to investigate oral cancer in pregnant women, a rare but therapeutically challenging patient subset. METHODS After institutional review board approval, an EMERSE search was used to identify all women treated at the University of Michigan from 1998 to 2010 with head and neck squamous cell carcinoma (HNSCC) during pregnancy. This identified 4 patients with tongue cancer. Biomarkers and human papillomavirus (HPV) were assessed by immunohistochemistry and multiplex PCR/mass spectrometry, respectively. RESULTS Two patients responded well to therapy and are alive more than 10 years after diagnosis; 2 patients died of disease. All tumors overexpressed EGFR and Bcl-xL, 3 of 4 overexpressed c-Met, both tumors that progressed overexpressed p53. All tumors were negative for HPV, p16, estrogen receptor, progesterone receptor, and HER-2. CONCLUSIONS Biomarkers of aggressive tumors (high EGFR, c-Met; high Bcl-xL-low p53) did not correlate with outcome. Additional studies are needed to determine whether perineural invasion, delay in diagnosis, and p53 overexpression are factors in poor survival.

Abstract
PURPOSE To evaluate cMET (mesenchymal-epithelial transition factor gene) and phospho-cMET (p-cMET) levels in breast cancer subtypes and its impact on survival outcomes. EXPERIMENTAL DESIGN We measured protein levels of cMET and p-cMET in 257 breast cancers using reverse phase protein array. Regression tree method and Martingale residual plots were applied to find best cutoff point for high and low levels. Kaplan-Meier survival curves were used to estimate relapse-free (RFS) and overall (OS) survival. Cox proportional hazards models were fit to determine associations of cMET/p-cMET with outcomes after adjustment for other characteristics. RESULTS Median age was 51 years. There were 140 (54.5%) hormone receptor (HR) positive, 53 (20.6%) HER2 positive, and 64 (24.9%) triple-negative tumors. Using selected cutoffs, 181 (70.4%) and 123 (47.9%) cancers had high levels of cMET and p-cMET, respectively. There were no significant differences in mean expression of cMET (P < 0.128) and p-cMET (P < 0.088) by breast cancer subtype. Dichotomized cMET and p-cMET level was a significant prognostic factor for RFS [HR: 2.44, 95% confidence interval (CI): 1.34-4.44, P = 0.003 and HR: 1.64, 95% CI: 1.04-2.60, P = 0.033] and OS (HR: 3.18, 95% CI: 1.43-7.11, P = 0.003 and HR: 1.92, 95% CI: 1.08-3.44, P = 0.025). Within breast cancer subtypes, high cMET levels were associated with worse RFS (P = 0.014) and OS (P = 0.006) in HR-positive tumors, and high p-cMET levels were associated with worse RFS (P = 0.019) and OS (P = 0.014) in HER2-positive breast cancers. In multivariable analysis, patients with high cMET had a significantly higher risk of recurrence (HR: 2.06, 95% CI: 1.08-3.94, P = 0.028) and death (HR: 2.81, 95% CI: 1.19-6.64, P = 0.019). High p-cMET level was associated with higher risk of recurrence (HR: 1.79, 95% CI: 1.08-2.95.77, P = 0.020). CONCLUSIONS High levels of cMET and p-cMET were seen in all breast cancer subtypes and correlated with poor prognosis.
