Bhalang K, Danuthai K. Expression of p53 in toluidine blue positive oral squamous cell carcinoma lesions and expression of Ki67 in vinegar positive oral squamous cell carcinoma lesions. FRONTIERS IN ORAL HEALTH 2023; 4:1239961. [PMID: 37876530 PMCID: PMC10593433 DOI: 10.3389/froh.2023.1239961] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2023] [Accepted: 09/20/2023] [Indexed: 10/26/2023] Open
Abstract
The aims of this study were to investigate the sensitivity and specificity of toluidine blue and/or vinegar in oral cancer screening and to examine the correlation between clinical screening using toluidine blue and vinegar and the expression of the tumor marker p53 and proliferation marker Ki67, respectively. The study consisted of 87 patients with suspected oral squamous cell carcinoma lesions. Toluidine blue and/or vinegar were applied to the lesions, followed by biopsies. The tissues were diagnosed histopathologically and underwent immunohistochemical process for p53 or Ki67. The results revealed that the sensitivity and specificity of oral cancer screening using toluidine blue were 93% and 46%, respectively; whereas the sensitivity and specificity using vinegar were 85% and 81%, respectively. A statistically significant correlation between the use of vinegar and the expression of Ki67 (p = 0.019) was observed. Although there was a difference in the expression of p53 between specimens that were positive and negative to toluidine blue, the correlation did not reach a significant level. Based on the results from this study, vinegar has a lower sensitivity than toluidine blue but a higher specificity for oral cancer screening. The results of the clinical screening using vinegar correlated with the expression of Ki67 at the cellular level.

Abstract
The prognosis of laryngeal cancer is affected by clinicopathological factors. Because of that, an effective prognostic marker is very valuable in managing the clinical process. The p53 evaluation method, used in the literature recently, was used for the first time in laryngeal cancer. We evaluated PTEN with 2 methods with the highest significance in the literature on laryngeal cancer. All demographic and histopathological data from 140 laryngeal cancers were compared with p53 and PTEN expressions and survival. p53 staining patterns were classified as wild and mutant. PTEN expression was evaluated according to the staining intensity named PTEN1 and according to the proportion of stained cells named PTEN2. In the series, 93.6% were males, and the mean survival was 38 months. 69.3% of cases were p53 mutants. PTEN loss was found to be 85.7% and 57.9%, respectively. Tumor size and thyroid cartilage invasion for PTEN1 and age for p53 were identified as independent predictive factors (P < .01). Advanced age, total laryngectomy, and extranodal spread were independent poor prognostic factors for overall survival and the presence of subglottic involvement, perineural invasion, and extranodal spread were for disease-free survival (P < .01). This is the first study in which the new p53 classification was used in laryngeal cancer, and will contribute significantly to the literature with differences from the previous evaluation patterns. Evaluation of PTEN based on staining intensity is more appropriate compared to the percentage of stained cells.

Abstract
BackgroundMetastasis dominates the prognosis of eyelid sebaceous carcinoma (SC). This study aimed to explore risk factors for nodal metastasis and develop a nomogram to predict nodal metastasis in patients with eyelid SC.MethodsA retrospective case–control study was performed, comprising 320 patients with eyelid SC. Cox analyses were employed to investigate predictors of metastasis-free survival (MFS), and a nomogram was established and validated by the bootstrap method.ResultsForty patients (12.5%) developed nodal metastasis during a median follow-up of 48.0 months, and the median period between the initial treatment and first nodal metastasis was 18.5 months (range 6.0–80.0 months). The 1-year, 3-year and 5-year nodal metastasis rates were 5.5%, 12.5% and 15.4%, respectively. Diffuse pattern (HR: 4.34, 95% CI 1.75 to 10.76, p=0.002), orbital invasion at presentation (HR: 3.22, 95% CI 1.42 to 7.33, p=0.005), perineural invasion (HR: 3.24, 95% CI 1.11 to 9.49, p=0.032) and high Ki-67 percentage (HR: 1.03, 95% CI 1.01 to 1.05, p<0.001) were identified as independent risk factors for nodal metastasis. A nomogram that integrated these four factors had a C-index of 0.785, demonstrating a strong power in predicting nodal metastasis of eyelid SC.ConclusionsWe identified risk factors for nodal metastasis and developed a nomogram to provide individualised estimates of nodal metastasis for eyelid SC patients and guide postoperative management. This nomogram contained clinicopathological factors besides the T category of the TNM staging system and suggesting great clinical value.

Abstract
Laryngeal carcinoma is the second common malignancy of the upper aerodigestive tract after lung cancer; in most cases is a squamous cell carcinoma, whose risk factors include tobacco smoking and alcohol consumption. Despite therapeutic progress, the five-year overall survival rate for this malignancy has remained nearly 50% and many patients already present metastasis at the time of diagnosis. To date, there are no tools that predict the evolution of laryngeal carcinoma: in this light, during the last years, many studies were planned with the aim to investigate the role played by different biomarkers expressed by larynx cancer, which can help make an early diagnosis, predict disease evolution and direct therapeutic choice. This review aims to summarize these markers and correlating them with disease evolution.

Abstract
Head and neck squamous cell carcinoma (HNSCC) is highly variable by tumor site, histologic type, molecular characteristics, and clinical outcome. During recent years, emerging targeted therapies have been focused on driver genes. HNSCC involves several genetic alterations, such as co-occurrence, multiple feedback loops, and cross-talk communications. These different kinds of genetic alterations interact with each other and mediate targeted therapy response. In the current review, it is emphasized that future treatment strategy in HNSCC will not solely be based on "synthetic lethality" approaches directed against overactivated genes. More importantly, biologic, genetic, and epigenetic alterations of HNSCC will be taken into consideration to guide the therapy. The emerging genetic alterations in HNSCC and its effect on targeted therapy response are discussed in detail. Hopefully, novel combination regimens for the treatment of HNSCC can be developed.

Abstract
The aim of this study was to determine the prognostic value of Ki-67 immunostaining in patients affected by laryngeal squamous cell carcinoma. A systematic review was carried out in a tertiary university referral center. An appropriate string was run on PubMed to retrieve articles dealing with Ki-67 immunohistochemical staining and laryngeal squamous cell carcinoma. A double cross-check was performed on citations and full-text articles by two investigators independently to review all manuscripts and perform a comprehensive quality assessment. Of 85 abstracts identified, 18 articles were included. These studies reported on 1,342 patients with histological confirmed diagnosis of laryngeal squamous cell carcinoma. Most studies showed a statistical association between Ki-67 immunohistochemical expression and at least one of the clinical and histopathological parameters considered by the authors. Overall the studies analyzed suggested that the tumoral proliferative index was statistically connected respectively with T stage (2/18), N stage (4/18), grading (6/18), disease-free survival (10/18) and overall survival (4/18). Our review strongly suggests that immunohistochemical staining of Ki-67 correlates with tumoral aggressiveness and worse prognosis in patients affected by laryngeal squamous cell carcinoma. Further high-quality prospective studies should be carried out to confirm our finding and determine the eventual differences between cancers of specific laryngeal subsites.

Abstract
Background The incidence of oropharyngeal squamous cell carcinoma (OPSCC) is increasing due to fundamental changes in oncogenesis related to effects of the human papilomavirus (HPV). Virally-mediated tumours behave and respond to treatment differently than their classic, carcinogenically-mediated counterparts despite similar stage and grade of disease. This difference in behaviour has lead to investigation of etiologies of OPSCC at the molecular level. Molecular biomarkers offer potential insight into the behaviour of OPSCC. Identifying a subset of patients that are more likely to have recurrence and distant metastasis is valuable for prognostication and treatment planning. There is limited information regarding the profiles of these biomarkers in locoregional and distant metastases in OPSCC. Objective This study was designed to identify biomarker profiles predictive of locoregional and distant metastases and recurrence in OPSCC. Methods Cross-sectional study of a prospectively-collected oropharyngeal tumour database was undertaken. All patients with OPSCC presenting to the University of Alberta Hospital from 2002-2009 were included in the study. Data collection from the Alberta Cancer Registry, including demographics, nodal status, distant metastases, treatment, recurrence, and survival, was undertaken. Tissue micro-arrays (TMAs) were constructed for each tumour specimen using triplicate cores (0.6mm) of formalin-fixed, paraffin-embedded (FFPE) pre-treatment tumour tissue. TMAs were processed using immunohistochemistry for p16, EGFR, Ki67, p53, and Bcl-XL. Positivity for each biomarker was determined using quantified AQUAnalysis ® scores on histoplots. Multivariate statistics were utilized to assess the relationship between each biomarker and locoregional and distant metastases, as well as recurrence-free survival (RFS). Results High expression of p16 (p=0.000) and Bcl-XL (p=0.039) independently demonstrated a significant association with nodal disease at presentation. Kaplan-Meier analysis demonstrated improved RFS in patients with high p16 and decreased RFS in patients with high p53 expression. Cox regression analysis supported p16 as an independent prognosticator for improved RFS. p53 demonstrated an association with recurrence, but when compared to p16 status, nodal status, and staging, was not an independent predictor of recurrence. Conclusions Biomarker profiling using p16, Bcl-xL, and p53 may be useful in prognostication and treatment planning in patients with OPSCC.

Abstract
We reinvestigated rearrangements occurring in region q13 of chromosome 11 aiming to: (i) describe heterogeneity of the observed structural alterations, (ii) estimate amplicon size and (iii) identify of oncogenes involved in laryngeal cancer progression as potential targets for therapy. The study included 17 cell lines derived from laryngeal cancers and 34 specimens from primary laryngeal tumors. The region 11q13 was analyzed by fluorescence in situ hybridization (FISH), array comparative genomic hybridization (aCGH) and gene expression microarray. Next, quantitative real time PCR was used for chosen genes to confirm results from aCGH and gene expression microarray. The observed pattern of aberrations allows to distinguish three ways, in which gain and amplification involving 11q13 region may occur: formation of a homogeneously staining region; breakpoints in/near 11q13, which lead to the three to sevenfold increase of the copy number of 11q13 region; the presence of additional copies of the whole chromosome 11. The minimal altered region of gain and/or amplification was limited to ~1.8 Mb (chr.11:69,395,184-71,209,568) and comprised mostly 11q13.3 band which contain 12 genes. Five, out of these genes (CCND1, ORAOV1, FADD, PPFIA1, CTTN) had higher expression levels in comparison to healthy controls. Apart from CCND1 gene, which has an established role in pathogenesis of head and neck cancers, CTTN, ORAOV1 and FADD genes appear to be oncogene-candidates in laryngeal cancers, while a function of PPFIA1 requires further studies.

Abstract
BACKGROUND The optimal management of advanced laryngeal and hypopharyngeal cancers (L&HC) must involve consideration of both survival and functional effect of the given treatment approach. Despite over two decades of investigations of several treatment options, including surgery, radiotherapy, chemotherapy or some combinations thereof, little consensus exists as to which treatment offers the best survival, together with functional speech and swallowing. AIM To determine predictive and prognostic value of p53, EGFr, Ki-67 in patients with advanced laryngeal and hypopharyngeal cancer, treated with larynx preservation intent. MATERIALS AND METHODS Thirty-three patients received 2-3 cycles of induction chemotherapy (ICHT) consisting of cisplatin and fluoruracil and underwent subsequent radical radiotherapy. Immunohistochemical analyzes of p53, EGFr and Ki-67 were performed. RESULTS Response to ICHT was obtained in 24 patients (75%). Better response to ICHT was correlated only with EGFr expression (p = 0.04, RR = 1.91). The 5-year loco-regional control (LRC) and disease-specific survival (DSS) rates were 48% and 57%, respectively. The 5-year larynx preservation rate was 68% in responders to ICHT compared to 21% in non-responders (p = 0.02). It was also higher in patients without EGFr expression (but not significantly, p = 0.43). CONCLUSION Lack of EGFr expression is a favorable predictive factor for response to ICHT. Neither p53 nor Ki-67 have predictive and prognostic value in larynx preservation treatment.

Abstract
Overexpression of Epidermal Growth Factor Receptor (EGFR) and also of cell cycle control proteins, such as cyclin D1 is a frequent event in squamous cell carcinoma of the larynx (LSSC). Our aim was to correlate their protein levels with telomerase catalytic subunit (h-TERT) expression. Using tissue microarray technology, fifty-five paraffin embedded histologically confirmed primary LSSCs and also ten dysplastic lesions were cored at a diameter of 1.5 mm. Immunohistochemistry (IHC) was performed by the use of anti-EGFR, anti-cyclin D1, and anti-h TERT monoclonal antibodies. Chromogenic in situ hybridization (CISH) analysis was also applied using EGFR gene and chromosome 7 probes, respectively. EGFR, cyclin D1 and h-TERT protein overexpression was observed in 48/55 (87.2%), 19/55 (34.5%) and 21/55 (38.1%) carcinoma cases, respectively. EGFR protein expression was statistically associated with grade (P=0.01), and also with stage (P=0.001) of the examined tumors. Borderline statistical significance was assessed correlating overall cyclin D1 expression to h TERT expression (P=0.06). Simultaneous up regulation of the three proteins was established in 7/55 (12.7%) cases, correlated to the stage of the tumors (P=0.05). EGFR gene amplification was observed in 7/65 (10.7%) carcinomas and dysplasias, whereas chromosome 7 aneuploidy was detected in 4/65 (6.1%) of those cases.Simultaneous up regulation of EGFR, cyclin D1 and h TERT proteins correlates with advanced stage in LSCC. EGFR gene amplification and not only protein over expression maybe is the eligible criterion for targeted therapeutic strategies in those patients.

Abstract
CONCLUSION These data indicate that the expression of p53, epidermal growth factor receptor (EGFR) or proliferating cell nuclear antigen (PCNA) is not a reliable predictor of the prognosis or the effect of adjuvant radiotherapy in patients with laryngeal squamous cell carcinoma (LSCC). OBJECTIVE The aim of this study was to investigate the prognostic significance of p53, EGFR, and PCNA in LSCC and to assess the relationships between the expression of these molecular markers and the effect of adjuvant radiotherapy. PATIENTS AND METHODS We retrospectively reviewed the expression of these molecular markers in 75 patients with LSCC. RESULTS None of the expressions of these molecular markers was associated with disease-free survival or overall survival and no significant correlations were found between them and the effect of adjuvant radiotherapy. Also, they were not associated with each other.

Abstract
CONCLUSION Contrary to most reports, our study shows that the expression of cyclin D1 is not an independent prognostic factor in patients with laryngeal cancer (LC). No correlation between cyclin D1 expression and survival rates in LC was found in a multivariate analysis. OBJECTIVES The aim of this study was to determine the possible relevance of the expression of cyclin D1 protein in LC as prognostic criteria and to analyse correlation of the expression with clinicopathological features and survival rates. MATERIALS AND METHODS Immunohistochemistry staining was used to detect the expression of cyclin D1 in 130 samples of laryngeal cancer and in 22 specimens of laryngeal nodules. RESULTS Cyclin D1 expression was found in 52 (40%) LC samples and in 3 (13.6%) samples of laryngeal nodules. There was no significant correlation between cyclin D1 expression and clinicopathological features of LC. A multivariate analysis of survival confirmed that cyclin D1 expression was not an independent prognostic factor in LC.

Abstract
BACKGROUND Although p53 overexpression is frequent in head and neck squamous cell carcinomas (HNSCCs), controversy remains regarding the prognostic significance of that overexpression. The objective of this study was to investigate the expression pattern and prognostic significance of p53 expression in HNSCC of the same location, treated in the same way, and with long-term follow-up. METHODS P53 expression was determined by immunohistochemistry in paraffin-embedded tissue specimens from 107 consecutive patients (107 primary squamous cell carcinomas of the supraglottic larynx and 46 matched lymph node metastases). All patients underwent surgical resection and bilateral neck dissection. RESULTS A strong correlation was observed between p53 expression in the primary tumor and in the matched lymph node metastases (P=.0001). P53 overexpression in the lymph nodes was an independent predictor of regional recurrence (P=.027). Likewise, expression of p53 in the lymph nodes correlated significantly with disease-specific survival (P=.018). Five years after treatment, 70% of patients with p53-negative, metastatic lymph nodes remained alive, whereas only 30% of patients with p53-positive lymph nodes remained alive. In multivariate analysis, lymph node status and p53 expression in the lymph nodes remained associated with survival. CONCLUSIONS The current data suggested that, although p53 overexpression is common in supraglottic carcinomas, its expression in the primary tumor is of limited clinical significance. However, the results supported the role of p53 in the lymph node metastases as an independent predictor of regional failure and a poor prognosis in patients with HNSCC. A prospective trial is indicated to validate these findings.

Abstract
Cyclin D1 is one of the key proteins involved in cell cycle control, and it is believed that its overexpression may be connected with tumorigenesis. A reason for cyclin D1 deregulation may be connected to a common G870A polymorphism at codon 242 in exon 4 of the CCND1 gene. This single nucleotide substitution, localized in the conserved splice donor site between exon 4 and the intron 4 boundary, might modulate the frequency of alternative splicing. It has been postulated that the A allele results in a higher level of mRNA (transcript b) encoding a protein with an altered C-terminal domain. The influence of CCND1 G-->A polymorphism for the risk of cancer and the prognosis of patients with different types of solid tumors has already been suggested. This study was conducted to investigate the association between the cyclin D1 gene polymorphism and laryngeal cancer risk, as well as the clinical outcome. We also examined the relationship between genotype/allele distributions and the cyclin D1 expression profile. The genotyping study was done using the PCR-RFLP method in 63 patients with larynx cancer and 102 healthy controls. The heterozygotic genotype GA as well as a combination of GA and AA genotypes were associated with an increased risk of larynx cancer compared to the GG genotype (OR =3.02; P =0.004 and OR =2.52; P =0.013, respectively). The A allele frequency was higher in cancer cases (0.484) than in controls (0.416) that were connected with a slightly increased risk of cancer development (OR =1.34); however, the difference was not significant. The AA genotype was associated with an early cancer onset compared to the GG genotype (median age: 51.5 and 63.0 years, respectively). We also demonstrated that the AA genotype was associated with the occurrence of lymph node metastases (OR =3.26) and a higher level of cyclin D1 overexpression. These results suggest that the CCND1 A allele may be a genetic factor that modulates the risk of larynx cancer development, and it may also have an effect on tumor biology and disease prognosis.

Abstract
Many factors affect the prognosis in operable laryngeal squamous cell carcinoma (LSCC). Many clinical factors have been implicated in tumor recurrence and poor survival of the patients. The aim of the present study is to investigate the demographic, clinical and histological characteristics as prognostic factors. Moreover, our aim is to analyze the role of modern molecular biomarkers in the prognosis of patients with LSCC. One hundred patients with operable laryngeal carcinoma underwent surgery as primary treatment between April 1999 and April 2002. Ninety-four of them were men and 6 women, with a median age of 62 years (39-77). All demographic data of the patients were recorded. Staging of the tumor revealed 20 cases with T2 cancer, 46 cases with T3 and 34 cases with T4, while N classification included 91 patients with N0 tumor, 3 with N1 and 6 with N2. Among the 100 cases, 47 were located in the glottis, 46 in the supraglottic region and 7 were transglottic. Histology grading revealed 35 cases of grade G1, 50 cases of G2 and 15 cases of G3. Postoperatively, all patients were followed regularly for the possibility of tumor relapse, with a median follow-up period of 40.2 months (4.8-58.4). During the operation, a tissue specimen was collected from the tumor. The specimens were used for RNA and DNA extraction. Isolated RNA was used to investigate the expression of wt-p53, bcl-2, VEGF and EGFR by the reverse transcriptase PCR method (RT-PCR) using specific primers, while genomic DNA was used for the detection of EBV and HPV (16/18 subtypes) by the consensus primer-mediated polymerase chain reaction method (PCR). All data such as tumor recurrence and survival were recorded. Statistical analysis was performed using the SPSS and STATA statistical packages in order to investigate the role of all clinical and molecular factors and their combinations as significant prognostic markers. The tumor recurrence rate was 31%, while the tumor associated death rate was 27% and total death rate 30%. Univariate analysis for overall survival showed significance for the T stage, TNM stage and site of the tumor. Univariate analysis for the time to progression showed significance for the T stage, N stage, TNM stage, site of the tumor and tumors simultaneously positive for EGFR and VEGF, while EGFR expression was borderline insignificant. Multivariate analysis revealed TNM stage as the only significant factor for overall survival, and TNM stage, site of the tumor and EGFR expression as significant factors for time to progression. The molecular biomarkers EGFR and VEGF have a prognostic significance in laryngeal cancer in addition to the established clinical prognostic factors such as the stage and site of the tumor. These markers, apart from their role in carcinogenesis, seem to play an important role in tumor relapse.
