[PMID: 36939422 DOI: 10.1002/ohn.219] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2022] [Revised: 11/02/2022] [Accepted: 11/19/2022] [Indexed: 01/30/2023]
Abstract
OBJECTIVE Angiogenesis is indeed a vital process in the progression of carcinomas, including that of larynx. Therefore, this study (AngLaC) aimed to identify candidate angiogenesis-related biomarkers in laryngeal carcinoma patients. STUDY DESIGN Prospective controlled cohort study. SETTING Tertiary referral center. METHODS In silico analyses of angiogenesis-related genes in laryngeal carcinoma were performed to determine candidate biomarkers. Serum levels of candidate biomarkers were determined via enzyme-linked immunosorbent assay in laryngeal carcinoma patients as well as in an age and gender-matched control group. The associations of the biomarkers with clinical parameters were investigated. RESULTS The study included 60 laryngeal carcinoma patients and 20 healthy controls. The serum levels of osteopontin, IGFBP-3, VEGF, sVEGFR-1, and VEGFR-2 were significantly higher in the patient group (p < .001, p ≤ .001, p < .001, p < .01, p < .01, respectively). High osteopontin and sVEGFR-1 levels were associated with locoregional-recurrence (p = .024, p = .016, respectively). IGFBP-3 had the highest diagnostic sensitivity (81.4%) and specificity (80%) among the molecules that were investigated (p < .001). High sVEGFR-1 and low VEGFR-2 levels were associated with poor overall-survival (p = .037, p = .027, respectively). High osteopontin and sVEGFR-1 levels were associated with poor disease-specific survival rates (p = .035, p = .018, respectively). CONCLUSION High serum levels of sVEGFR-1 and osteopontin as well as low serum levels of VEGFR-2 proved to be poor prognostic in terms of survival in laryngeal carcinoma. VEGF, sVEGFR1, VEGFR2, IGFBP-3, and osteopontin levels were found to be significantly increased in larynx cancer patients compared to the normal population. Further studies on osteopontin and sVEGFR-1 are required in order to determine their associations with recurrence.

Abstract
Larynx carcinoma (LC) is the most prevalent head and neck cancer among adults. LC xenograft mouse model was generated to verify the effect of VEGF on macrophage polarization and tumor growth in vivo. EdU assay was performed to measure the cell proliferation. Transwell assay was applied to assess cell migration. The expression of YAP and STAT3 was also significantly increased in LC tumor tissues. Moreover, both YAP and STAT3 overexpression in LC cells promoted the proliferation, migration, as well as the secretion of PD-L1 in M2-like TAMs. Mechanistically, the interaction between YAP and STAT3 facilitated the transcription of VEGF. Moreover, with a co-culture system, VEGF secretion in LC cells enhanced PD-L1 expression in M2-like TAMs via activating VEGFR1-TGFβ signaling pathway. Furthermore, VEGF secreted from LC cells also promoted the tumor growth of LC in vivo. We revealed that dysregulated YAP/STAT3 activity in LC cells could enhance the secretion of VEGF, which then functioned on M2-like TAMs via activating VEGFR1-TGFββ pathway to promote the expression of PD-L1 and immunosuppressive function of M2-like TAMs. Therefore, VEGF and PD-L1 might have a pivotal crosstalk between M2-like TAMs and LC cells, which provided a novel therapeutic target in regulating the metastasis of LC in future.

Abstract
BACKGROUND CEACAM1, a valuable biomarker for several cancers, have remained unexplored up to the present in laryngeal squamous cell carcinoma (LSCC). We aimed to examine CEACAM1 expression and evaluate its combinational clinical significance for the diagnosis or prognosis and treatment decision making in LSCC. METHODS CEACAM1 expression was assessed by immunohistochemistry in 54 LSCCs and evaluate its correlation with clinical and histopathological features. RESULTS CEACAM subtype 1 (CEACAM1) expression was positive in 50% of the cases. No significant difference was observed in relation to age, gender, tumor size, and tumor stage. CEACAM1 expression correlated with tumor grade, development of local recurrence, node and distant metastasis. Kaplan-Meier survival curves showed that CEACAM1 staining was inversely correlated with both overall and disease-specific 5-year survival. CONCLUSIONS Our study is the first to demonstrate that CEACAM1 expression is associated with an adverse prognosis in LSCC. CEACAM1 is a valuable biomarker and a promising therapeutic target in LSCC.

Abstract
Background Patients suffering from squamous cell carcinoma of the larynx (LSCC) with lymphatic metastasis have a relatively poor prognosis and often require radical therapeutic management. The mechanisms which drive metastasis to the lymph nodes are largely unknown but may be promoted by a pro-angiogenic tumor microenvironment. In this study, we examined whether the number of microvessels and the expression level of vascular endothelial growth factor (VEGF) in the primary tumor are correlated with the degree of lymph node metastasis (N-stage), tumor staging (T) and survival time in LSCC patients. Methods Tissue-Microarrays of 97 LSCC patients were analyzed using immunohistochemistry. The expression of VEGF was scored as intensity of staining (low vs high) and the number of CD31-positive vessels (median </≥7 vessels per visual field) was counted manually. Scores were correlated with N-stage, T-stage and 5-year overall survival rate. Results A high expression of angiogenic biomarkers was not associated with poor overall survival in the overall cohort of patients. Instead high CD31 count was associated with early stage cancer (p = 0.004) and in this subgroup high VEGF expression correlated with poor survival (p = 0.032). Additionally, in early stage cancer a high vessel count was associated with an increased recurrence rate (p = 0.004). Conclusion Only in the early stage subgroup a high expression of angiogenic biomarkers was associated with reduced survival and an increased rate of recurrence. Thus, biomarkers of angiogenesis may be useful to identify high risk patients specifically in early stage LSCC.

Abstract
Background: Overexpression of proangiogenic vascular endothelial growth factor A family VEGFAxxx is associated with tumor growth and metastasis. The role of the alternatively spliced antiangiogenic family VEGFAxxxb is poorly investigated in head and neck squamous cell carcinomas (HNSCCs). The antiangiogenic isoform binds to bevacizumab and its expression level could influence the treatment response and progression-free survival. In this study, the relative expression of VEGFAxxx and VEGFA165b isoforms and splicing regulatory factors genes was investigated in a series of HNSCCs. Methods: VEGFAxxx, VEGFA165b, SRSF6, SRSF5, SRSF1 and SRPK1 gene expression was quantified by quantitative real time PCR in 53 tissue samples obtained by surgery from HNSCC patients. Protein expression was evaluated by immunohistochemistry. Results: VEGFAxxx and VEGFA165b were overexpressed in HNSCCs. Elevated protein expression was also confirmed. However, VEGFA isoforms demonstrated differential expression according to anatomical sites. VEGFAxxx was overexpressed in pharyngeal tumors while the VEGFA165b isoform was up-regulated in oral tumors. The VEGFA165b isoform was also positively correlated with expression of the splicing regulatory genes SRSF1, SRSF6 and SRSF5. Conclusions: We concluded that VEGFAxxx and VEGFA165b isoforms are overexpressed in HNSCCs and the splicing regulatory factors SRSF1, SRSF6, SRSF5 and SRPK1 may contribute to alternative splicing of the VEGFA gene. The findings for the differential expression of the antiangiogenic isoform in HNSCCs could facilitate effective therapeutic strategies for the management of these tumors.

Abstract
The development of laryngeal squamous cell carcinoma (LSCC) is a multistep process involving multiple factors. MicroRNAs, a group of important negative regulators of gene expression, have also been confirmed to be involved in the LSCC pathogenesis. In the present study, we compared the expression of nine selected microRNAs in the LSCC tissues and adjacent nontumor tissues. We found that the expression of miR-203 was significantly reduced in the LSCC tissues. Predicted by using bioinformatics tools, we found that VEGFA and cyclooxygenase-2 (Cox-2) may be direct targets of miR-203. By subsequent determination through dual-luciferase assay and Western blot, we confirmed that miR-203 suppresses the expression of VEGFA and Cox-2 by directly targeting 3'-untranslated region. Meanwhile, by analyzing the relationship between miR-203 and VEGFA in clinical tissue samples, we found that a negative correlation existed in the expression of miR-203 and VEGFA (P=0.0096, r=-0.33). Similarly, the expression of miR-203 and Cox-2 also has a negative correlation (P=0.0019, r=-0.46). Subsequently, in vitro functional study indicated that miR-203 played as a tumor suppressor by repressing proliferation, migration, and invasion of Hep-2 cells. The overexpression of VEGFA partially rescued the effect of overexpressed miR-203. Overexpressed Cox-2 partially rescued the effect of miR-203 on Hep-2 cell proliferation but not on the cell migration and invasion capacity. These findings suggest that miR-203 plays as a tumor suppressor in LSCC, partially by regulating VEGFA and Cox-2, and may serve as a potential target for therapeutic intervention.

Brush cytology with immunocytochemical evaluation of VEGF expression versus biopsy in clinically precancerous laryngeal lesions: can we diagnose laryngeal cancer only with brush cytology? Anal Cell Pathol (Amst) 2015; 2015:256182.

Abstract
Introduction. Laryngeal squamous cell carcinoma (LSCC) is the most common SCC of the head and neck. The high incidence of this malignancy and the low survival rate necessitate the development of novel diagnostic approaches. Aim of this study is to compare the diagnostic value of laryngeal brush cytology combined with VEGF immunocytochemistry versus histopathology of clinically precancerous lesions of the larynx. Material and Methods. Thirty patients with precancerous or suspected malignant laryngeal lesions underwent microlaryngoscopy, during which samples were taken for cytological, immunocytochemical, and histological analysis. Cytology and histology results were classified as follows: benign lesions, atypia/moderate dysplasia, and malignancy, whereas the expression of VEGF was evaluated as strong, moderate, weak, and zero expression, based on the percentage of cells stained. Results. The cytology results were in accordance with the histology results in 86.7% of the patients. The exfoliative cytology's sensitivity was estimated at 85% and its specificity at 90%. Its positive prognostic value was 94%, while its negative prognostic value was 75%. The additional immunocytochemical evaluation of VEGF expression increased all the noted parameters. Discussion. Exfoliative cytology of laryngeal lesions is a minimal-invasive, easily applicable procedure during microlaryngoscopy and reliable in terms of diagnostic value. Under certain conditions it could be held also in local anesthesia. Concurrent immunocytochemical analysis of VEGF expression further enhances its diagnostic value.

Abstract
Cancer neovascularization plays an essential role in the metastasis of larynx carcinoma (LC). However, the underlying molecular mechanisms are not completely understood. Recently, we reported that placental growth factor (PLGF) regulates expression of matrix metalloproteinase 3 (MMP3) through ERK/MAPK signaling pathway in LC. Here, we show that MMP9 upregulated in LC, and appeared to be mainly produced by M2 macrophages (tumor-associated macrophages (TAM)). In a transwell co-culture system, PLGF secreted by LC cells triggered macrophage polarization to a TAM subtype that releases MMP9. Moreover, MMP9 was found to be activated in the PLGF-polarized TAM via transforming growth factor β (TGFβ) receptor signaling activation. Furthermore, PLGF in LC cells induced macrophage polarization in vivo, and significantly promoted the growth of LC. Thus, together with our previous work, our study highlights a pivotal role of cross-talk between TAM and LC in regulating the metastasis of LC.

Abstract
INTRODUCTION Squamous cell carcinoma is the most common neoplasm of the larynx, and its evolution depends on tumor staging. Vascular endothelial growth factor is a marker of angiogenesis, and its expression may be related to increased tumor aggressiveness, as evidenced by the presence of cervical lymphatic metastases. OBJECTIVES To evaluate the expression of the vascular endothelial growth factor marker in non-glottic advanced squamous cell carcinoma of the larynx (T3/T4) and correlate it with the presence of cervical lymph node metastases. METHODS Retrospective clinical study and immunohistochemical analysis of vascular endothelial growth factor through the German scale of immunoreactivity in products of non-glottic squamous cell carcinomas. RESULTS This study analyzed 15 cases of advanced non-glottic laryngeal tumors (T3/T4), four of which exhibited cervical lymphatic metastases. There was no correlation between vascular endothelial growth factor expression and the presence of cervical metastases. CONCLUSION Although vascular endothelial growth factor was expressed in a few cases, there was no correlation with the spread of cervical lymph metastases.

Abstract
Introduction Vascular endothelial growth factor is thought to be an important angiogenic factor involved in tumor growth, progression, and metastasis. Objective The present study evaluated the relation between tissue expression, serum and salivary levels of vascular endothelial growth factor in head and neck squamous cell carcinomas, and their correlation with clinicopathologic features. Methods Samples were collected from 30 patients with head and neck squamous cell carcinomas and 24 healthy volunteers. Immunohistochemical analysis was used for tissue expression and enzyme-linked immunosorbent assay was employed to measure serum and salivary levels. Results No vascular endothelial growth factor staining was observed in normal tissues, whereas vascular endothelial growth factor expression was seen in 6 patients (20%). Mean serum level of VEGF was 83.7 ± 104.47 in patients and 50.04 ± 32.94 in controls. Mean salivary level of vascular endothelial growth factor was 174.41 ± 115.07 in patients and 149.58 ± 101.88 in controls. No significant difference was found by Mann–Whitney test between controls and patients (p = 0.411, p = 0.944, respectively). No correlation was found between vascular endothelial growth factor tissue expression and its serum and salivary level. Conclusion Overexpression of vascular endothelial growth factor was found in head and neck squamous cell carcinoma patients, suggesting its role in the pathogenesis of head and neck squamous cell carcinoma, but no relation was found between tissue expression, serum levels, and salivary levels of this marker.

Abstract
Background and purpose CD44 variants have been associated with tumor invasion and metastasis, but CD44 expression patterns have not been systematically investigated in pancreatic carcinoma. This study systematically investigated whether CD44 expression patterns are involved in pancreatic carcinoma metastasis and prognosis. Methods We applied primers specific for all CD44 variants and CD44s to analyze the expression patterns of CD44 (CD44v2-CD44v10 and CD44s) using quantitative real-time PCR (qRT-PCR). We then further evaluated their roles in pancreatic carcinoma metastasis and prognosis using clinical survival analysis. Results Increased CD44v expression and decreased CD44s expression were found in metastatic pancreatic carcinoma in three different cell lines and in human tumor tissue. Clinical analysis showed that CD44v6+ and CD44v9+ were correlated with lymph node metastasis, liver metastasis and TNM stage. However, CD44s− was associated with liver metastasis, tumor differentiation and TNM stage. Survival analysis showed that patients with CD44v6+/CD44s− or CD44v6+/CD44s− had lower overall survival (OS) rates, although the individual expression of CD44v6, CD44v9 and CD44s was also related to decreased OS rates. Univariate analysis showed that lymph node metastasis; vessel invasion; hepatic metastases; TNM stage; and individual or co-expression of CD44v6, CD44v9 and CD44s were risk factors affecting survival. Multivariate analysis showed that CD44v6+/CD44s− was an independent predictor of survival. Conclusions We found that CD44v6+, CD44v9+ and CD44s− were associated with pancreatic carcinoma metastasis and progression and that CD44v6+/CD44s− was an independent risk factor affecting survival in pancreatic carcinoma. Therefore, the different expression patterns of CD44v/CD44s may determine pancreatic carcinoma prognosis.

Over 2,200 cases of carcinoma of the larynx are diagnosed in the UK annually, with an overall 5-year survival rate of 67%. Angiogenesis is vital for the growth and metastasis of solid tumours and the expression of key angiogenesis-related proteins has been shown to be of prognostic significance. In this study we reported the expression of key angiogenesis-related factors, selected from a pilot array study, in a cohort of laryngeal tumours and associated metastatic lymph nodes. Forty patients diagnosed with squamous cell carcinoma of the larynx were recruited. Tissue specimens were obtained intra-operatively, prior to chemo- and/or radiotherapy, from the tumours and secondary lymph nodes. The patient group comprised 32 men and 8 women with a mean age of 68 years (range, 51-89 years). The relative expression of the angiogenesis-related proteins angiogenin, interleukin (IL)-8, tissue inhibitor of metalloproteinases-1 (TIMP-1), vascular endothelial growth factor (VEGF), fibroblast growth factor (FGF)-basic and insulin-like growth factor binding protein 3 (IGFBP3) was determined in the tissue lysates by ELISA. The expression of angiogenin was higher in early-stage compared with late-stage tumours (P=0.034) and the expression of IGFBP3 was higher in tumours compared with the metastatic lymph nodes (P=0.016). No statistically significant differences were recorded for VEGF, FGF, TIMP-1 or IL-8 between tumour stages or primary tumours and lymph nodes. To the best of our knowledge, this study was the first to investigate multiple angiogenic factors in the lysates of laryngeal carcinomas and metastatic nodes and identified angiogenin and IGFBP3 as factors possibly involved in tumour progression. A greater understanding of their function may offer novel prognostic and/or therapeutic options.

Abstract
Objectives Alterations in mitochondrial DNA (mtDNA) copy number have been widely reported in various human cancers, and been considered to be an important hallmark of cancers. However, little is known about the value of copy number variations of mtDNA in the prognostic evaluation of laryngeal cancer. Design and methods Using real-time quantitative PCR method, we investigated mtDNA copy number in a cohort of laryngeal cancers (n =204) and normal laryngeal tissues (n =40), and explored the association of variable mtDNA copy number with clinical outcomes of laryngeal cancer patients. Results Our data showed that the relative mean mtDNA content was higher in the laryngeal cancer patients (11.91 ± 4.35 copies) than the control subjects (4.72 ± 0.70 copies). Moreover, we found that mtDNA content was negatively associated with cigarette smoking (pack-years), tumor invasion, and TNM stage. Notably, variable mtDNA content did not affect overall survival of laryngeal cancer patients. However, when the patients were categorized into early-stage and late-stage tumor groups according to TNM stage, we found that low mtDNA content was strongly associated with poor survival in the former, but not in the latter. Conclusions The present study demonstrated that low mtDNA content was strongly correlated with some of clinicopathological characteristics, such as cigarette smoking, tumor invasion and TNM stage. In addition, we found a strong link between low mtDNA content and worse survival of the patients with early-stage tumors. Taken together, low copy number of mtDNA may be a useful poor prognostic factor for early-stage laryngeal cancer patients.

The relationship between lymphatic vascular density and vascular endothelial growth factor A (VEGF-A) expression with clinical-pathological features and survival in pancreatic adenocarcinomas.

Abstract
BACKGROUND Pancreatic cancer is a rare tumor with an extremely low survival rate. Its known risk factors include the chronic use of tobacco and excessive alcohol consumption and the presence of chronic inflammatory diseases, such as pancreatitis and type 2 diabetes. Angiogenesis and lymphangiogenesis, which have been the focus of recent research, are considered prognostic factors for cancer development. Knowing the angiogenic and lymphangiogenic profiles of a tumor may provide new insights for designing treatments according to the different properties of the tumor. The aim of this study was to evaluate the density of blood and lymphatic vessels, and the expression of VEGF-A, in pancreatic adenocarcinomas, as well as the relationship between blood and lymphatic vascular density and the prognostically important clinical-pathological features of pancreatic tumors. METHODS Paraffin blocks containing tumor samples from 100 patients who were diagnosed with pancreatic cancer between 1990 and 2010 were used to construct a tissue microarray. VEGF expression was assessed in these samples by immunohistochemistry. To assess the lymphatic and vascular properties of the tumors, 63 cases that contained sufficient material were sectioned routinely. The sections were then stained with the D2-40 antibody to identify the lymphatic vessels and with a CD34 antibody to identify the blood vessels. The vessels were counted individually with the Leica Application Suite v4 program. All statistical analyses were performed using SPSS 18.0 (Chicago, IL, USA) software, and p values ≤ 0.05 were considered significant. RESULTS In the Cox regression analysis, advanced age (p=0.03) and a history of type 2 diabetes (p=0.014) or chronic pancreatitis (p=0.02) were shown to be prognostic factors for pancreatic cancer. Blood vessel density (BVD) had no relationship with clinical-pathological features or death. Lymphatic vessel density (LVD) was inversely correlated with death (p=0.002), and by Kaplan-Meyer survival analysis, we found a significant association between low LVD (p=0.021), VEGF expression (p=0.023) and low patient survival. CONCLUSIONS Pancreatic carcinogenesis is related to a history of chronic inflammatory processes, such as type 2 diabetes and chronic pancreatitis. In pancreatic cancer development, lymphangiogenesis can be considered an early event that enables the dissemination of metastases. VEGF expression and low LVD can be considered as poor prognostic factors as tumors with this profile are fast growing and highly aggressive.

Abstract
The tumor stroma is comprised of extracellular matrix, non-malignant cells, and the signaling molecules they produce. It is an integral and vital component of primary tumors that together with the underlying genetic defects in the tumor cells determines the growth characteristics, morphology, and invasiveness of the tumor. In parallel to continuing genetic changes in the tumor cells themselves, the tumor stroma progressively evolves during primary tumor development. Cancer cells that disseminate from primary tumors are dependent on this stromal microenvironment, and therefore the microenvironment they encounter at secondary sites determines their fate. For those cells that survive at these sites, stromal progression can serve to re-establish a supportive tumor stroma, fostering the outgrowth of the cells as metastases. Formation of a metastatic niche that supports the survival and growth of disseminated tumor cells is a key feature of this stromal progression. The endogenous organ microenvironment can provide components of the metastatic niche. In addition, microenvironmental changes in organs prior to receipt of disseminated tumor cells can be induced by factors secreted systemically by primary tumors, causing the formation of pre-metastatic niches. Further maturation of metastatic niches can be responsible for the re-activation of dormant disseminated tumor cells many years after removal of the primary tumor. The concept of the metastatic niche and stromal progression has profound consequences for our understanding of metastatic disease, and promises to open up new strategies for the diagnosis, prognostic evaluation, and therapy of cancer.

Abstract
Laryngeal carcinoma is a common head and neck cancer with poor prognosis. Patients with laryngeal carcinoma usually present late leading to the reduced treatment efficacy and high rate of recurrence. Despite the advance in the use of molecular markers for monitoring human cancers in the past decades, there are still no reliable markers for use to screen laryngeal carcinoma and follow the patients after treatment. Epigenetics emerged as an important field in understanding the biology of the human malignancies. Epigenetic alterations refer to the dysregulation of gene, which do not involve the alterations of the DNA sequence. Major epigenetic changes including methylation imbalance, histone modification, and small RNA dysregulation could play a role in the development of human malignancies. Global epigenetic change is now regarded as a molecular signature of cancer. The characteristics and behavior of a cancer could be predicted based on the specific epigenetic pattern. We here provide a review on the understanding of epigenetic dysregulation in laryngeal carcinoma. Further knowledge on the initiation and progression of laryngeal carcinoma at epigenetic level could promote the translation of the knowledge to clinical use.
