[PMID: 36857878 DOI: 10.1016/j.archoralbio.2023.105661] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2022] [Revised: 02/19/2023] [Accepted: 02/21/2023] [Indexed: 02/24/2023]
Abstract
OBJECTIVE To characterize the epidemiological, clinical, and prognostic features of multiple primary cancers (MPC) following oral squamous cell carcinoma (OSCC). DESIGN Data from the Surveillance, Epidemiology, and End Results Program database were analyzed to determine the standardized incidence ratio (SIR) of multiple subsequent sites, difference in clinical and prognostic features between MPC and single primary OSCC. RESULTS The sites with the highest SIRs were the oral cavity (SIR = 69.48), other oral cavity and pharynx (SIR=55.46), pharynx (SIR=39.21), tonsils (SIR=33.52), trachea (SIR=33.24), esophagus (SIR=18.00), and larynx (SIR=13.12). The 5- and 10-year survival rates for single primary OSCC were 57.9% (95% CI: 56.7-59.2%) and 47.1% (95% CI: 45.7-48.6%), respectively, while those for MPC were 66.9% (95% CI: 64.6-69.4%) and 42.2% (95% CI: 39.5-45.2%), respectively. The mean age of MPC patients was significantly higher than that of single primary OSCC patients. MPC are more common in the gums and other sites of the oral cavity, and more likely to be detected in early TNM stage and pathological grade. Age, site, T-stage, and N-stage were significantly associated with prognosis of MPC. CONCLUSIONS Significant differences in clinical and prognostic features were found between MPC and single primary OSCC. Considering MPC has a poor long-term prognosis, it is necessary to identify MPC and single primary OSCC early.

Abstract
Oral cavity squamous cell carcinoma (OCSCC) is one of the most common head and neck cancers worldwide. It is well known that risk factors for OCSCC include tobacco and excess alcohol consumption. However, in recent years, OCSCC incidence has been increasing in patients without these traditional risk factors. The cause of this increase is unclear and various genetic, environmental, and infectious factors have been hypothesized to play a role. Additionally, there are expert opinions that oral cancer in non-smoking, non-drinking (NSND) patients have a distinct phenotype resulting in more aggressive disease presentation and poorer prognosis. In this review, we summarize the current state of knowledge for oral cavity cancer in patients without traditional risk factors.

Abstract
OBJECTIVES To investigate the clinical and pathological features of multiple primary malignant neoplasms (MPMNs) cases. METHODS The clinical data of 24 105 tumour patients admitted to Jiangsu Cancer Hospital in 2018 were retrospectively reviewed, and 270 patients with MPMNs were selected as the research subjects. Among them, 101 cases of synchronous carcinoma (SC) and 92 cases of metachronous carcinoma (MC) were divided into groups for statistical analysis. Univariate and multivariate cox regression analyses were conducted using SPSS 22.0 software. RESULTS Among 24 105 cases, there was a male-to-female ratio of 1.45:1. Compared with MC cases, SC patients have a higher proportion of male cases. Primary neoplasms in gastric cancer, head and neck cancer, oesophageal cancer and colon cancer occupied most cases in male MPMNs, while primary breast cancer ranked first in female MPMNs. In addition, the leading secondary neoplasms were duodenal carcinoma, lung cancer and male MPMNs and lung cancer in female MPMNs. As for SC MPMNs, primary neoplasms were occupied by lung cancer, gastric cancer and oesophageal cancer, while the secondary neoplasms were mostly consisted of oesophageal cancer and lung cancer. Finally, the MC MPMNs were mostly consisted of breast cancer and gastric cancer as primary neoplasms, while lung cancer and oesophageal cancer as secondary neoplasms. CONCLUSIONS Screening for primary cancer should be strengthened over the age of 50 years for male patients with gastric cancer or female patients with breast cancer to reduce or monitor the occurrence of MPMNs.

[PMID: 34313009 PMCID: PMC8419750 DOI: 10.1002/cam4.4142] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2019] [Revised: 05/28/2021] [Accepted: 06/24/2021] [Indexed: 11/09/2022] Open
Abstract
Head and neck squamous cell carcinoma (HNSCC) is a common malignancy worldwide with a poor prognosis. DNA methylation is an epigenetic modification that plays a critical role in the etiology and pathogenesis of HNSCC. The current study aimed to develop a predictive methylation signature based on bioinformatics analysis to improve the prognosis and optimize therapeutic outcome in HNSCC. Clinical information and methylation sequencing data of patients with HNSCC were downloaded from The Cancer Genome Atlas database. The R package was used to identify differentially methylated genes (DMGs) between HNSCC and adjacent normal tissues. We identified 22 DMGs associated with 246 differentially methylated sites. Patients with HNSCC were classified into training and test groups. Cox regression analysis was used to build a risk score formula based on the five methylation sites (cg26428455, cg13754259, cg17421709, cg19229344, and cg11668749) in the training group. The Kaplan–Meier survival curves showed that the overall survival (OS) rates were significantly different between the high‐ and low‐risk groups sorted by the signature in the training group (median: 1.38 vs. 1.57 years, log‐rank test, p < 0.001). The predictive power was then validated in the test group (median: 1.34 vs. 1.75 years, log‐rank test, p < 0.001). The area under the receiver operating characteristic curve (area under the curve) based on the signature for predicting the 5‐year survival rates, was 0.7 in the training and 0.73 in test groups, respectively. The results of multivariate Cox regression analysis showed that the riskscore (RS) signature based on the five methylation sites was an independent prognostic tool for OS prediction in patients. In addition, a predictive nomogram model that incorporated the RS signature and patient clinical information was developed. The innovative methylation signature‐based model developed in our study represents a robust prognostic tool for guiding clinical therapy and predicting the OS in patients with HNSCC.

Presence of Human Papillomavirus and Epstein-Barr Virus, but Absence of Merkel Cell Polyomavirus, in Head and Neck Cancer of Non-Smokers and Non-Drinkers. Front Oncol 2021; 10:560434.

Abstract
OBJECTIVE Determine the presence and prognostic value of human papillomavirus (HPV), Epstein-Barr virus (EBV), Merkel cell polyomavirus (MCPyV), and cell cycle proteins in head and neck squamous cell carcinoma (HNSCC) of non-smokers and non-drinkers (NSND). METHODS Clinical characteristics and tumors of 119 NSND with HNSCC were retrospectively collected and analyzed on tissue microarrays. RNAscope in situ hybridization (ISH) was used to screen for the presence of HPV and MCPyV mRNA. Immunohistochemistry was performed for expression of p16 as surrogate marker for HPV, Large T-antigen for MCPyV, and cell cycle proteins p53 and pRb. Positive virus results were confirmed with polymerase chain reaction. For EBV, EBV encoded RNA ISH was performed. Differences in 5-year survival between virus positive and negative tumors were determined by log rank analysis. RESULTS All oropharyngeal tumors (OPSCC) (n = 10) were HPV-positive, in addition to one oral (OSCC) and one nasopharyngeal tumor (NPSCC). The other three NPSCC were EBV-positive. MCPyV was not detected. Patients with HPV or EBV positive tumors did not have a significantly better 5-year disease free or overall survival. Over 70% of virus negative OSCC showed mutant-type p53 expression. CONCLUSION In this cohort, all OPSCC and NPSCC showed HPV or EBV presence. Besides one OSCC, all other oral (n = 94), hypopharyngeal (n = 1), and laryngeal (n = 9) tumors were HPV, EBV, and MCPyV negative. This argues against a central role of these viruses in the ethiopathogenesis of tumors outside the oro- and nasopharynx in NSND. So, for the majority of NSND with virus negative OSCC, more research is needed to understand the carcinogenic mechanisms in order to consider targeted therapeutic options.

Abstract
BACKGROUND Panendoscopy is routinely used for the identification of occult second primary tumours in head and neck squamous cell carcinoma. However, its role in low risk subgroups, particularly non-smoking, non-drinking patients and patients presenting with early stage oral cavity lesions, is debatable. METHODS The records of 112 patients with T₁ or T₂ oral tongue squamous cell carcinoma were retrospectively reviewed. Demographic, disease characteristics and survival data were collected. RESULTS Average follow-up duration was 71.7 months (range, 3.6-238.3 months). Thirty-five patients died within this period. Thirteen second primary events were identified in 11 patients, with all but 2 tumours in the oral cavity or oropharynx. There was a single synchronous primary - a lung adenocarcinoma; all other events were metachronous. No non-smoking, non-drinking patients re-presented with a second primary tumour; tobacco and alcohol use are clearly risk factors for development of a second primary tumour. CONCLUSION The role of panendoscopy for identifying synchronous primary tumours in patients with early stage oral tongue squamous cell carcinoma should be re-evaluated, particularly in non-smoking, non-drinking patients who are at low risk of second primary development. Close follow up with regular clinical examination including flexible fibre-optic endoscopy may be sufficient in this subgroup.

Abstract
AIM This manuscript aims to describe an unusual case of multiple second primary squamous cell carcinomas (SCCs) in several sites of the oral mucosa in a nonsmoker and nondrinker woman and to discuss the diagnostic criteria, clinicopathological aspects and outcome of second primary tumor (SPT). BACKGROUND Patients treated for SCC of the head and neck are at high risk for developing SPT arising from the same dysplastic mucosal feld. Currently, there is no reliable method to predict which of the patients will develop SPT. CASE DESCRIPTION A 64-year-old nonsmoker and nondrinker woman developed several second primary oral SCCs in 7 years of follow-up, most of them being synchronic, treated by surgery without and with chemotherapy and radiotherapy. CONCLUSION Patients treated for SCC require a long-term and careful follow-up as the development of SPT contributes with significantly negative impact on the prognosis. CLINICAL SIGNIFICANCE This report describes the diagnosis and management of a very unusual case of several SPTs affecting different sites of the oral mucosa in the same patient. Moreover, the patient had no apparent risk factors associated with the development of the oral cancer. Therefore, a brief update concerning SPT and its diagnosis and management is also provided.

Abstract
BACKGROUND A small, albeit significant, number of head and neck squamous cell carcinoma (HNSCC) patients has no history of tobacco and alcohol use. Such non-habits associated HNSCCs may represent a distinct clinical entity and exhibit increased aggressiveness. The objective of the study was to understand differences in molecular etiology of habits, and non-habits associated tongue carcinomas. MATERIALS AND METHODS High-throughput gene expression profiling of 22 tumor samples was carried out. This was followed by quantitative real-time PCR validation of four of the identified differentially expressed genes. RESULTS AND CONCLUSION Eighteen genes were identified that correlate strongly with the habits- and non-habits distinction. Among the genes significantly overexpressed in the non-habits group are CCND1, a key cell-cycle regulator, DACT3, a modulator of the Wnt/beta-catenin pathway, and three genes associated with the Notch signaling pathway. CCND1 and DACT3 overexpression in non-habits associated tongue carcinomas were subsequently validated by quantitative real-time PCR in an independent cohort (n = 18) of patient samples. Gene expression data were integrated with publicly available protein interaction data to build a small protein interaction network containing five of 18 differentially expressed genes. This suggested that a functional 'network module' can be implicated in the subgroup distinction. All the tumors analyzed here were human papillomavirus (HPV) negative samples. An association between CCND1 overexpression in oral tumors and poor prognosis has previously been reported. Thus, CCND1 overexpression in non-habits associated anterior tongue carcinomas may contribute to their increased clinical aggressiveness.

Abstract
BACKGROUND/AIM The TP53 gene is a tumor suppressor gene. Its product is a nuclear protein that regulates cell cycle arrest, apoptosis and DNA repair. Anti-p53 clones DO-7 and PAb-240 recognize the amino acid sequences 21-25 and 213-217, respectively. This study aimed to evaluate the expression of these clones and their relationship with clinicopathological features and survival analysis in oral squamous cell carcinomas (OSCC). METHODS Information on 53 primary OSCC was collected at the Brazilian National Cancer Institute. An immunohistochemical method was applied to evaluate p53 expression (DO-7 and PAb-240). Their expression was analyzed quantitatively and correlated with clinicopathological features. Kaplan-Meier survival curves and log rank test were used. RESULTS Immunopositivity for DO-7 was present in 64% of the cases, while 58% were positive for PAb-240. There was no correlation between immunoexpression of both antibodies and clinicopathological features or survival analysis. DO-7 expression was significantly higher (p = 0.001) than that of PAb-240. CONCLUSIONS There were quantitative differences between the expression of the antibodies studied, which may reflect a different specificity of each one. To confirm immunohistochemical results and estimate the true prognostic role of TP53 in OSCC, it is important to perform mutation analysis.

Abstract
The aim of this study was to investigate the effects of a single exposure to whole cigarette smoke on human gingival fibroblast behavior. Normal oral mucosa fibroblasts were exposed once to whole cigarette smoke for 5, 15, or 30 min, and then were used to analyze cell adhesion, β1-integrin expression, cell growth and viability, cell capacity to contract collagen gel, and cell migration following wound infliction. Our findings showed that when gingival fibroblasts were exposed once to whole cigarette smoke, this resulted in a significant inhibition of cell adhesion, a decrease in the number of β1-integrin-positive cells, increased LDH activity in the target cells, and reduced growth. The smoke-exposed fibroblasts were also not able to contract collagen gel matrix and migrate following insult. Overall results demonstrate that a single exposure to whole cigarette smoke produced significant morphological and functional deregulation in gingival fibroblasts. This may explain the higher predisposition of tobacco users to oral infections and diseases such as cancer.

Abstract
INTRODUCTION Susceptibility to head and neck squamous cell carcinoma may be modified by functional polymorphisms in genes involved in the folate pathway, such as cystathionine beta-synthase (CBS). The CBS 844ins68 polymorphism is associated with DNA methylation changes and cancer development. MATERIAL AND METHODS A case-control retrospective study was conducted in 322 patients with head and neck squamous cell carcinoma and in 531 control subjects without cancer. The polymerase chain reaction-restriction fragment length polymorphism technique was used to genotype the polymorphism. For statistical analysis, χ(2) test was conducted to examine whether the genotypic frequency of CBS 844ins68 was in Hardy-Weinberg equilibrium and multiple logistic regression was used for comparisons between groups, and for interactions between the polymorphism and risk factors and clinical histopathological parameters. RESULTS No significant difference in CBS 844ins68 genotypic distribution was observed between the groups. Age > 50 years, male gender and tobacco consumption were predictors of the disease with increased risk of 7.89 (95% CI: 5.56-11.21), 2.49 (95% CI: 1.72-3.62), 6.44 (95% CI: 4.63-8.96) and 2.29 times (95% CI: 1.71-3.06) respectively. There was no association between the distribution of the CBS 844ins68 genotype and risk factors for this disease. According to clinical histopathological parameters, CBS 884ins68 polymorphism presented high frequency in oral cavity (p < 0.05) and patients with the polymorphism presented less survival time (p < 0.05). CONCLUSIONS We concluded that the CBS 844ins68 polymorphism is not associated with HNSCC risk and there is increased risk of this disease in male gender individuals smokers aged over 50 years. In adittion, the polymorphism is more frequent in patients with oral cavity as primary site and in patients with less survival time.

Abstract
OBJECTIVE Our aim was to validate the use of tissue microarrays (TMA) in oral squamous cell carcinomas (OSCC) to analyse epidermal growth factor receptor (EGFR) and Ki-67 expression. We also analysed the relationship that the expression of these markers may have with clinical, pathological and survival variables. PATIENTS AND METHODS The study sample comprised 39 unselected patients diagnosed and treated for OSCC. We analysed Ki-67 and EGFR expression by immunohistochemistry on formalin-fixed, paraffin-embedded surgical specimens. Whole sections (WS) were compared with double 1.5 mm core-tissue microarrays. RESULTS High EGFR expression was observed both on TMA (in 98% of the cases) and WS (in 100% of the cases) with substantial agreement kappa value (0.720). EGFR expression was not significantly associated with clinical, pathological and survival variables on TMA and WS. Ki-67 analysis showed a Spearman correlation of 0.741 with a Ki-67 mean labelling index of 45% in TMA and 56.8% in WS. We found a significant relationship between gender and Ki-67 labelling index on WS (P = 0.022) and TMA (P = 0.002). Clinical stage was the only parameter in multivariate analysis that had a significant predictive value. CONCLUSION We demonstrate that dual 1.5 mm core TMA is a valid, rapid, economical and tissue-saving way to study OSCC biopsies and that it presents strong correlation with the WS. EGFR overexpression in OSCC suggests that these tumours may be a candidate for therapy investigation directed to EGFR.

Abstract
BACKGROUND Local or regional lymph node recurrence is the most common pattern of treatment failure in oral squamous cell carcinoma (SCC). The local recurrence rate is 30% even when the surgical resection margin is diagnosed as tumour free. Accumulation of genetic changes in histologically normal epithelium in the surgical resection margin may explain the local recurrence rate. The purpose of this study is to investigate the presence of senescence markers, which may represent early malignant changes in the margin that in routine pathological evaluations are classified as histologically normal. METHODS Formalin-fixed, paraffin-embedded surgical specimens from 16 consecutive patients with oral SCC and a clear surgical margin were obtained. The margin was analysed by immunohistochemistry for p53, p16, Chk2, Laminin-5 and glycosylated oncofetal fibronectin. RESULTS Two patterns of p53 expression were found in the histologically normal epithelium in the surgical resection margin. One was characterized by no protein expression in the majority of cells, except for small clusters of basal and parabasal cells with nuclear staining. The other was characterized by p53 expression in the nuclei of most basal cells. The expression of p16 was confined to small groups of cells in the basal cell layer whereas Chk2 was only seen in one case. Upregulation of the stromal proteins, Laminin-5 or glycosylated oncofetal fibronectin, was only seen at regions of invasion. CONCLUSION Small groups of cells expressing p53 and p16 were found in the surgical resection margin that appeared to be histologically normal and may represent early malignant changes.
