Cancer Cell Int 2024; 24:228. [PMID: 38951897 PMCID: PMC11218202 DOI: 10.1186/s12935-024-03417-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2024] [Accepted: 06/22/2024] [Indexed: 07/03/2024] Open
Abstract
BACKGROUND In the treatment of oral cavity cancer, margin status is one of the most critical prognostic factors. Positive margins are associated with higher local recurrence and lower survival rates. Therefore, the universal goal of oral surgical oncology is to achieve microscopically clear margins. Near-infrared fluorescence guided surgery (FGS) could improve surgical resection using fluorescent probes. αVβ6 integrin has shown great potential for cancer targeting due to its overexpression in oral cancers. Red fluorescent contrast agent IRDye 680 coupled with anti-αVβ6 peptide (IRDye-A20) represents an asset to improve FGS of oral cancer. This study investigates the potential of IRDye-A20 as a selective imaging agent in 3D three-dimensional tongue cancer cells. METHODS αVβ6 integrin expression was evaluated by RT-qPCR and Western Blotting in 2D HSC-3 human tongue cancer cells and MRC-5 human fibroblasts. Targeting ability of IRDye-A20 was studied in both cell lines by flow cytometry technique. 3D tumor spheroid models, homotypic (HSC-3) and stroma-enriched heterotypic (HSC-3/MRC-5) spheroids were produced by liquid overlay procedure and further characterized using (immuno)histological and fluorescence-based techniques. IRDye-A20 selectivity was evaluated in each type of spheroids and each cell population. RESULTS αVβ6 integrin was overexpressed in 2D HSC-3 cancer cells but not in MRC-5 fibroblasts and consistently, only HSC-3 were labelled with IRDye-A20. Round shaped spheroids with an average diameter of 400 μm were produced with a final ratio of 55%/45% between HSC-3 and MRC-5 cells, respectively. Immunofluorescence experiments demonstrated an uniform expression of αVβ6 integrin in homotypic spheroid, while its expression was restricted to cancer cells only in heterotypic spheroid. In stroma-enriched 3D model, Cytokeratin 19 and E-cadherin were expressed only by cancer cells while vimentin and fibronectin were expressed by fibroblasts. Using flow cytometry, we demonstrated that IRDye-A20 labeled the whole homotypic spheroid, while in the heterotypic model all cancer cells were highly fluorescent, with a negligible fluorescence in fibroblasts. CONCLUSIONS The present study demonstrated an efficient selective targeting of A20FMDV2-conjugated IRDye 680 in 3D tongue cancer cells stroma-enriched spheroids. Thus, IRDye-A20 could be a promising candidate for the future development of the fluorescence-guided surgery of oral cancers.

Abstract
INTRODUCTION A diagnosis of oral squamous cell carcinoma in adolescent patients is extremely rare. When an oral squamous cell carcinoma lesion arises near the teeth and/or periodontium, it can be easily misdiagnosed as an inflammatory condition of endodontic or periodontal origin. METHODS This is a case report of an otherwise healthy 14-year-old patient who was referred for endodontic evaluation and treatment of a soft-tissue swelling in the anterior maxilla. RESULTS The unexpected definitive diagnosis of invasive oral squamous cell carcinoma underscores the importance of proper diagnostic testing. CONCLUSIONS Accurate interpretation of pulp testing results, periapical and cone beam computed tomography imaging, timely biopsy, and prompt definitive treatment are critical when a lesion of nonodontogenic origin is suspected.

Abstract
In a scenario where there is an increased incidence of oral squamous cell carcinoma (OSCC) in younger age groups, the diagnosis of pseudo-malignant lesions that mimic the histopathology of a moderate or even high-grade carcinoma becomes imperative for oral pathologists. Though paediatric malignancies such as melanomas and thyroid carcinomas and even OSCCs have been reported in young children, they are rare in the pre-pubertal age group. Melanocytic naevi such as Spitz naevi (SNs) or atypical SNs is, however, more common in this age group and could create some difficulty in diagnosis due to its histological variations that could mimic a malignancy. Hence, the need for a cautious correlation between clinical and histopathological features becomes manifold. Adjunct tools that use diagnostic and molecular techniques such as immunohistochemistry (IHC) and comparative genomic hybridisation (CGH) help in diagnosis and in differentiating certain types of SNs from Spitzoid melanomas or melanomas. A case that histopathologically resembled a moderately differentiated squamous cell carcinoma without any evidence of melanocytic content proved to be a melanocytic naevus after clinical correlation of both age and immunohistochemical analysis. This case report with review brings to light the importance of being aware of such pseudo-malignant lesions in our daily practice.

Abstract
Background: The objective of this study is to assess whether the impact of marital status on oral tongue squamous cell carcinomas (OTSCC) prognosis varied by gender, age, and race. Methods: We examined the clinicopathological variables using chi-squared tests, and we evaluated the association between survival and different variables using the methods of Kaplan-Meier. Univariate and multivariate analyses were performed to determine the effects of each variable on survival. Results: A total of 5282 patients were analyzed. The rate of being married was higher among Asian or Caucasian, and this rate decreased with higher tumor stage. While both married male and female survivors benefit from their marital status, we found a differential in OS based on gender, with females benefiting more than males (male P = .038; female P = .009, respectively). Patients who were divorced/separated/widowed (male HR = 1.275, 95% CI: 1.085-1.499; female HR = 1.313, 95% CI: 1.083-1.593) and never married (male HR = 1.164, 95% CI: 0.983-1.378; female HR = 1.224, 95% CI: 0.958-1.565) had increased hazard of OS compared with married/partnered patients (male P = .038; female P = .009). Subgroups analysis shows that the effect of marital status was significantly associated with treatment outcome only in Caucasian patients aged 50 years or older who harbored non-metastatic disease and received surgery (P < .001). Conclusion: While there are survival benefits for married patients with OTSCC, married/partnered females may benefit more than males. Age, race, and gender could affect the correlation between marital status and survival.

Abstract
The present systematic review aimed to assess the prevalence of oral HPV-related lesions, categorized as benign (verruca vulgaris "VV", squamous cell papilloma "SP", condyloma acuminata "CA", and focal epithelial hyperplasia "FEH") and malignant (oral squamous cell carcinoma "OSCC"), in descending order of occurrence in pediatric subjects (≤18 years of age). The secondary objectives were to evaluate the frequency and types of oral lesions described in relation to HPV genotypes and the HPV vaccine type (if any). The study protocol, compliant with the PRISMA statement, was registered at PROSPERO (CRD42022352268). Data from 60 studies, of which quality was assessed using the ROBINS-I tool, were independently extracted and synthesized. Along with seven poorly described benign HPV-related oral lesions that could not be categorized, a total of 146 HPV-related oral lesions, namely 47.26% (n = 69) VV, SP, and CA, 51.37% (n = 75) FEH, and 1.37% (n = 2) OSSC, were diagnosed in 153 pediatric subjects (M:F ratio = 1:1.4) with a mean age of lesion onset of 8.46 years. The viral genotypes detected were HPV-13 (30.61%), -6 (20.41%), -11 (16.33%), HPV-2 (12.24%), -32 (10.20%), -57 (6.12%), and -16 (4.08%). No HPV vaccination was reported in any case. Further studies should be conducted to evaluate the prevalence of HPV-related benign and malignant lesions and the potential role of HPV and associated vaccination in oral carcinogenesis in pediatric subjects.

Abstract
This review gives a brief history of the development of head and neck pathology in Europe from a humble beginning in the 1930s to the explosive activities the last 15 years. During the decades before the introduction of immunohistochemistry in the 1980s, head and neck pathology grew as a subspeciality in many European countries. In the late 1940s, the Institute of Laryngology and Otology with its own pathology laboratory was founded in London, and in 1964 the World Health Organization (WHO) International Reference Centre for the Histological Classification of Salivary Tumours was established at the Bland-Sutton Institute of Pathology, also in London. International collaboration, and very much so in Europe, led to the publication of the first WHO Classification of Salivary Gland Tumours in 1972. In the 1960s, a salivary gland register was organised in Hamburg and in Cologne the microlaryngoscopy was invented enabling microscopic endoscopic examination and rather shortly afterwards a carbon dioxide laser attached to the microscope became established and laryngeal lesions could be treated by laser vaporisation. During the last three decades, the use of immunohistochemistry supplemented with cytogenetic and refined molecular techniques has greatly facilitated the pathological diagnostics of head and neck lesions and has had a huge impact on research. Collaboration between different European centres has drastically increased partly due to establishment of scientific societies such as the Head and Neck Working Group (HNWG) within the European Society of Pathology and the International Head and Neck Scientific Group (IHNSG). A very large number of European pathologists have contributed to the 2nd, 3rd and 4th WHO books, and are involved in the upcoming 5th edition. Accredited educational meetings and courses are nowadays regularly arranged in Europe. Numerous textbooks on head and neck pathology have been written and edited by European pathologists. The increased collaboration has created larger series of tumours for research and new entities, mainly defined by their genetic abnormalities, are continuously emerging from Europe, particularly regarding salivary gland neoplasms and "undifferentiated" sinonasal tumours. These findings have led to a better and more precise classification and open the possibilities for new treatment strategies.

Abstract
BACKGROUND The objective of this study is to evaluate the early mortality rate and associated factors for early death in oral tongue squamous cell carcinomas (OTSCC) patients. METHODS Patients with OTSCC were extracted from the SEER database between 2004 and 2014. The early death (survival time≤3 months) rate was calculated, and associated risk factors were evaluated by the logistic regression models. RESULTS A total of 7756 patients were analysed and 282 (3.6%) patients died within 3 months after cancer diagnosis, among whom 214 (2.8%) patients died from cancer-specific cause. In univariate analyses, advanced age, divorced/single/widowed (DSW), higher histological grades, black, advanced T stage, advanced N stage, distant metastasis and no surgery were significantly associated with all-causes and cancer-specific early death. Multivariate analyses showed that advanced age, DSW, advanced T stage, advanced N stage, distant metastasis, and no surgery were significantly associated with all-cause and cancer-specific early death. CONCLUSION Our results showed that a total of 3.6% patients with OTSCC suffered early death. Predictors of early death are primarily related to age older than 60 years, advanced T stage, advanced N stage, distant metastasis and no surgery but also include unmarried status, but better prognostic and predictive tools in larger sample to select early death patients are needed.

Abstract
BACKGROUND Malignant neoplasms that affect children and adolescents are predominantly embryonic and generally affect blood system cells and supporting tissues. AIM This study aimed to summarize the scientific evidence about the prevalence of malignant lesions in the oral cavity of children and adolescents. DESIGN In this systematic review and meta-analysis (PROSPERO CRD42020158338), data were obtained from seven databases and the gray literature. Cross-sectional observational studies on the prevalence of biopsied oral pediatric malignancies were included. The Newcastle-Ottawa Scale assessed the quality of the included studies, and the GRADE approach evaluated the evidence certainty. The meta-analysis prevalence was calculated using MedCalc® software, adopting a 95% confidence level (CI; random-effect model). RESULTS Forty-two studies were included in the meta-analysis. Of the 64,522 biopsies, the prevalence of malignant lesions was 1.93% (n = 1,100; 95% CI = 1.21%-2.80%). Countries with a low socioeconomic profile showed the highest prevalence. The sample size did not influence the prevalence of oral malignancies, and unspecified lymphomas (12.08%; 95% CI = 5.73%-20.37%) and rhabdomyosarcoma (10.53%; 95% CI = 7.28%-14.30%) were the most common lesions. CONCLUSIONS Oral malignant lesions biopsied in children and adolescents had a prevalence of <3%, and lymphomas and sarcomas were the most prevalent lesions.

Abstract
Regulatory functions of circRNAs by targeting the micro RNA (miRNA)/mRNA axis have been increasingly found in oral squamous cell carcinoma (OSCC). CircRNA keratin 1 (CircKRT1) and miR-495-3p were dysregulated in OSCC. Programmed death ligand 1 (PDL1) was an important immunotherapeutic molecule in OSCC. Our objective was to explore whether circKRT1 could regulate cancer progression and immune evasion in OSCC by affecting the miR-495-3p/PDL1 axis. RNA expression was examined by quantitative real-time polymerase chain reaction. All protein levels were detected by western blot. OSCC cell growth was assessed by CCK-8 and colony formation assays. Cell migratory and invasive abilities were evaluated by transwell assay. CD8+ T-cell cytotoxicity was determined via lactate dehydrogenase assay. CD8+ T-cell percentage and apoptosis were analyzed by flow cytometry. Target screening was performed by Veen Diagram and RNA pull-down assay. Target binding was verified using dual-luciferase reporter and RNA immunoprecipitation assays. A xenograft in mice was conducted for in vivo experiment. CircKRT1 and PDL1 were highly expressed in OSCC tissues and cells. CircKRT1 knockdown repressed OSCC cell growth, migration, invasion, epithelial-mesenchymal transition, and CD8+ T-cell apoptosis, but enhanced CD8+ T cytotoxicity and percentage. The inhibitory effects of circKRT1 downregulation on OSCC progression and immune evasion were related to PDL1 expression inhibition. CircKRT1 sponged miR-495-3p and miR-495-3p targeted PDL1. OSCC progression and immune evasion were regulated by circKRT1 via the miR-495-3p/PDL1 axis. CircKRT1 also facilitated OSCC progression in vivo by regulating miR-495-3p and PDL1. This study clarified that circKRT1 worked as a miR-495-3p sponge to regulate PDL1, consequently affecting cancer progression and immune evasion in OSCC.

Abstract
OBJECTIVE To report the signalment, staging, surgical treatment, and survival time of juvenile dogs treated surgically for oral squamous cell carcinoma (OSCC). STUDY DESIGN Retrospective study. ANIMALS OR SAMPLE POPULATION Twenty-five dogs, <2 years of age with OSCC treated with surgery. METHODS Cases were solicited from the Veterinary Society of Surgical Oncology. Data retrieved included sex, breed, age, weight, clinical signs, tumor location, preoperative diagnostics and staging, histopathological diagnosis with margin evaluation, disease-free interval, and date and cause of death. A minimum follow-up time of 3 months was required for inclusion. RESULTS Eighteen dogs were <12 months of age, and seven were <24 months. Various breeds were represented, with a mean body weight of 22.3 ± 14.4 kg. No dogs had evidence of metastatic disease prior to surgery. All dogs underwent partial maxillectomy or mandibulectomy. Histological margins were complete in 24 dogs and incomplete in one. No dogs had evidence of metastatic disease or tumor recurrence. The median follow-up time was 1556 days (92 to 4234 days). All dogs were alive at the last follow-up except for one documented death, due to dilated cardiomyopathy. Median disease-specific survival time was not reached. CONCLUSION The prognosis after wide surgical excision of OSCC in juvenile dogs was excellent. CLINICAL SIGNIFICANCE OSCC in juvenile dogs can be effectively treated with surgery alone.

Abstract
Pediatric hematologic malignancies present an elevated survival rate, and these survivors may experience long-term complications, including secondary malignancies. This case describes a 17-year-old female patient previously treated for acute lymphoblastic leukemia (ALL) who developed a squamous cell carcinoma (SCC, T2N0M0) of the lateral border of the tongue diagnosed during dental follow-up 2 years and 9 months after the conclusion of ALL therapy (GBTLILLA99 protocol). The patient underwent exclusive surgical resection for the tongue SCC and is free of disease 11 years after the surgery. The current case report highlights the importance of monitoring the oral health of childhood cancer survivors. As part of a multidisciplinary team, our directives include counseling to avoid carcinogenic exposures.

Abstract
The objective of this study is to assess prognostic value of surgery for elderly oral tongue squamous cell carcinomas (OTSCC) patients. Patients with OTSCC were extracted from the SEER database between 2010 and 2014. The distributions of categorical demographic and clinicopathological characteristics were determined for different age groups: the 75-79, 80-84, and 85-102 years old groups. Univariate and multivariate analyses were performed to determine the effects of each variable on survival. A total of 1064 patients were analyzed. 75-79 years old patients tended to be male and rate of surgery declined with advancing age (P < 0.001). 75-79 years old patients more frequently presented with advanced stage compared to their older peers (P = 0.002). Compared to surgery groups, the hazard ratios for no surgery groups were 2.856 (95% CI 2.267-3.599; (P < 0.001)) for OS and 3.687 (95% CI 2.561-5.308; (P < 0.001)) for CSS in multivariable analysis. In subgroup analysis, the effect of no surgery was significantly associated with a higher risk of poor CSS in patients aged 75-79 years, 80-84 years and 85-102 years (P < 0.001, respectively). Our results showed that there were a series of factors contributing to poor outcomes in the elderly OTSCC patients, including clinicopathological characteristics and surgical management. Surgical resection is significantly associated with an improved OS and CSS, but further exploration in larger prospective clinical trials and better prognostic and predictive tools for select old patients for surgery are needed.

Abstract
Background Aim of this study was to describe the outcome of patients with gingival squamous cell carcinoma (GSCC), and to recognize aspects affecting clinical course and to consider survival rate.
Material and Methods The case records of patients, over a 10-year period, were retrospectively examined. Differences in distribution of the potential risk factors by prognosis were investigated through non-parametrical tests (Wilcoxon Rank-Sum and Fisher’s Exact). Survival curves for age, therapy and stage were built by the Kaplan-Meier method and compared with Log-Rank test.
Results 79 patients were analysed. Significant increase in mortality for patients older than 77 and for those with advanced stages was found. Cumulative survival rate 5 years after the diagnosis was 43%, while at 10 years was of 11%.
Conclusions With a statistical relationship between age and tumour stage with survival rates, and 70% of GSCC cases identified as stage IV, early GSCC diagnosis remains challenging. Key words:Gingival cancer, clinical appearance, treatment, retrospective study.

Abstract
The tongue squamous cell carcinoma (TSCC) is a highly prevalent head and neck cancer often associated with tobacco and/or alcohol abuse or high-risk human papillomavirus (HR-HPV) infection. HPV positive TSCCs present a unique mechanism of tumorigenesis as compared to tobacco and alcohol-induced TSCCs and show a better prognosis when treated. The poor prognosis and/or recurrence of TSCC is due to presence of a small subpopulation of tumor-initiating tongue cancer stem cells (TCSCs) that are intrinsically resistant to conventional chemoradio-therapies enabling cancer to relapse. Therefore, targeting TCSCs may provide efficient therapeutic strategy for relapse-free survival of TSCC patients. Indeed, the development of new TCSC targeting therapeutic approaches for the successful elimination of HPV+ve/-ve TCSCs could be achieved either by targeting the self-renewal pathways, epithelial mesenchymal transition, vascular niche, nanoparticles-based therapy, induction of differentiation, chemoradio-sensitization of TCSCs or TCSC-derived exosome-based drug delivery and inhibition of HPV oncogenes or by regulating epigenetic pathways. In this review, we have discussed all these potential approaches and highlighted several important signaling pathways/networks involved in the formation and maintenance of TCSCs, which are targetable as novel therapeutic targets to sensitize/eliminate TCSCs and to improve survival of TSCC patients.

Abstract
PURPOSE The purpose of this study was to describe 3 cases of tongue cancer in patients less than 21 years of age. Secondarily, a literature review was performed to examine disease presentation, risk factors, prognosis, and treatment strategies for young persons with tongue cancer. METHODS The authors presented 3 cases of childhood tongue cancer between 2009 and 2020 at the University of Michigan Department of Oral and Maxillofacial Surgery (Ann Arbor, MI). An electronic literature review was conducted via PubMed, Embase, Web of Science, and MLibrary. RESULTS Including the present case series, 64 studies reporting 108 cases were identified. Age at presentation ranged from newborn to 20 years, with a mean age of 14.5 years. The majority of patients were female (52.2%); 68.1% of patients presented with T1 or T2 disease. Nodal metastases were seen in 56.1% of patients. The most commonly identified predisposing factors included Fanconi anemia (13.9%), bone marrow transplant (9.3%), tobacco use (6.5%), and xeroderma pigmentosum (4.6%). Most patients received surgery alone (37.5%), followed by surgery with adjuvant radiation (33.8%); 60.6% underwent neck dissection. Overall survival was 60.3% at 1 year and 43.6% at 5 years. CONCLUSIONS Oral tongue cancer in the young is a rare disease with poorly understood etiology. There is a need for oncologists and maxillofacial surgeons to collaborate in the study of genetic, social, environmental, and medical risk factors contributing to the disease. All patients should undergo high-throughput genetic sequencing to expand our understanding of the disease process and allow for targeted treatment strategies.

Abstract
BACKGROUND To assess clinicopathological characteristics and prognostic value of age stratification on overall survival (OS) and cancer-specific survival (CSS) for stage IV oral tongue squamous cell carcinoma. METHODS A total of 1357 patients were extracted from the SEER database between 2010 and 2014. RESULTS Younger patients tended to be male and present with advanced N classification and advancing age increases the risk of cancer related death. Subgroups analysis shows that the effect of advancing age was significantly associated with a higher risk of poor survival in non-Asian who harbored T2/T3/T4a, N2b/N2c or non-metastatic disease (all p < 0.05). CONCLUSIONS In high-risk patients, tumor characteristics rather than age should be considered when making treatment decisions.

Abstract
Epithelial-to-mesenchymal transition (EMT) is key to invasion and metastasis by oral squamous carcinoma (OSCC) cells. MicroRNAs (miRNAs) such as miRNA-146a are known to be upregulated in OSCC. However, it is unclear whether they are involved in driving EMT. Here, we investigated the effect of miR-146a overexpression on proliferation, migration, and EMT in OSCC cells. OSCC cells were transfected with a plasmid expressing miR-146a precursor. Cell lines that stably overexpressed miRNA-146a were assessed for proliferation, colony formation, and invasiveness in vitro. Expression of markers and regulators of EMT, cell motility, and invasion were measured by qRT-PCR and western blot. Potential miRNA-146a binding sites in the 3'UTR of ST8SIA4 were identified by bioinformatic analysis. To confirm that miRNA-146a binds to and regulates ST8SIA4, we transfected OSCC cell lines with miRNA-146a mimics and a luciferase reporter construct containing either the wild type or mutant 3'UTR of ST8SIA4. OSCC cell lines that overexpressed miR-146a displayed higher proliferation, colony formation, invasion, and MMP-2 activity than cells transfected with a control vector. Overexpression of miR-146a also decreased expression of the epithelial cell marker E-cadherin and increased expression of Twist1, a transcription factor that promotes EMT, as well as markers associated with mesenchymal cells (vimentin and N-cadherin) and tumor invasion (p-paxillin and p-cortactin). Luciferase expression was lower in OSCC cells transfected with miRNA-146a mimics or with luciferase constructs carrying the wild type, but not mutant, 3'UTR of ST8SIA4. Overexpression of miR-146a promotes EMT phenotypes and may drive tumorigenesis and progression in OSCC, making it a useful target for future OSCC treatments.

Abstract
Regulatory T (Treg) cells can suppress antitumor immune response, but little is known about possible age-related differences in the number of these cells in the microenvironment of oral tongue squamous cell carcinoma (OTSCC). The aim of this study was to determine the number of FoxP3+ Treg cells in the microenvironment of OTSCC in young (≤ 45 years) and older (≥ 60 years) patients, and to correlate the findings with clinicopathological parameters (sex, tumor size/extent, regional lymph node metastasis, clinical staging, and histopathological grade of malignancy). Forty-eight OTSCCs (24 diagnosed in young patients and 24 diagnosed in older patients) were selected. Lymphocytes exhibiting nuclear immunopositivity for FoxP3 were quantified at the tumor invasive front and the results were analyzed statistically using the non-parametric Mann-Whitney test. FoxP3+ lymphocytes were observed in all cases assessed. The number of FoxP3+ lymphocytes in OTSCC tended to be higher in older patients (p = 0.055). Analysis of OTSCC in males and in early clinical stages revealed a higher number of Treg cells in older patients than in young ones (p < 0.05). In older patients, the number of Treg cells tended to be higher in smaller tumors (p = 0.079). Tumors with intense inflammatory infiltrate exhibited a larger number of Treg cells, both in young (p = 0.099) and older patients (p = 0.005). The results suggest a greater participation of Treg cells in immunoinflammatory responses in the microenvironment of OTSCC in older patients, particularly in males and in early stages.

Abstract
Oral cancer in children is rare. Diagnosis may be delayed as a result of confusion with reactive lesions. Furthermore, cancer staging, with or without bony invasion, can be complicated during tooth eruption. Literature on pediatric oral cancers is lacking, making determination of the possible etiopathology difficult. We describe an exceptional case of a 5-year-old male child who presented with anterior maxillary gingival pseudoepitheliomatous hyperplasia that progressed to carcinoma cuniculatum with invasive oral squamous cell carcinoma (OSCC). Because of the interesting timing of events, we hypothesize that human papillomavirus (HPV) inoculation through cutaneous squamous papilloma played a contributory role. A review of similar case reports in the literature is included. Biopsy of suspicious oral lesions should not be delayed because of the young age of the patient. Atypical hyperplasia should include squamous cell carcinoma (SCC) in the differential diagnoses. For surgical management of aggressive lesions during the mixed dentition, permanent successors should be included in the surgical margins to prevent recurrence.

Abstract
Many studies have shown that FZD2 is significantly associated with tumor development and tumor metastasis. The purpose of the present study was to gain insight into the role of FZD2 in the cell proliferation and invasion of tongue squamous cell carcinoma. According to TCGA-HNSC dataset, among the 10 Frizzled receptors, FZD2 exhibited the highest degree of differential expression between cancer tissues and normal tissues, and the overall survival of patients with higher FZD2 levels was shown to be significantly shorter compared with those with lower FZD2 levels. The upregulation of FZD2 in clinical tongue cancer tissues was validated by real-time PCR. Knockdown of FZD2 inhibited the proliferation, migration and invasion of CAL-27 and TCA-8113 cells, whereas overexpression of FZD2 led to the opposite results. Further analysis revealed that FZD2 is positively correlated with WNT3A, WNT5B, WNT7A and WNT2 and is negatively correlated with WNT4. These results indicated that FZD2 may act as an oncogene in tongue squamous cell carcinoma. Therefore, FZD2 may be a target for the diagnosis, prognosis and gene therapy of tongue cancer.

Abstract
To examine differences in survival and clinical outcomes of elderly patients without traditional risk factors presenting with oral squamous cell carcinoma. Retrospective review of 287 consecutive patients divided into 2 treatment period cohorts treated for oral SCC between the 1st Jan 2007 and 31st Dec 2012. Patients were classified as either smoker-drinkers (SD) or non-smoking, non-drinking (NSND). Only patients with oral sub-site primaries according to ICD-10 were included. Carcinomas of the lip, tonsil, base of tongue and oro-pharyngeal subsites were excluded. Of the study population (N = 287), 24.4% were NSND and 9.75% were NSND elderly (older than 70 years) females. >50% of tumours arose from the oral tongue in NSND patients (p = 0.022) and there was a higher rate of recurrent and persistent disease (42.9% vs 27.6%, p = 0.005). Disease specific survival at 5 years was significantly reduced when NSND elderly females were compared to all other patients (p < 0.001) as well as age matched controls (p = 0.006). This effect was verified independently in each cohort.The results of this study suggest that NSND elderly females are a distinct patient population with poorer disease specific survival outcomes.

Abstract
OBJECTIVES Tongue squamous cell carcinoma (TSCC) is a clinically devastating disease. However, most established TSCC cell lines currently show undesirable malignant behaviours. The purpose of this study is to establish a highly metastatic TSCC cell line to serve as a useful tool for basic research. MATERIALS AND METHODS TSCCs were induced by 4-nitroquinoline-1-oxide (4NQO) in Sprague-Dawley rats. Tumor cells were obtained from the cancer tissues by primary culture and were then purified by an in vitro invasion assay and a limiting dilution assay. The growth rate, cell cycle distribution, apoptotic rate, tumorigenicity and distant metastatic phenotypes of the rat tongue cancer cells were fully investigated and characterized. RESULTS To date, the rat tongue cancer cell line, named Rca-T, has been continuously cultured in vitro for over 210 passages and exhibit a long spindle-shaped morphology, adherent growth, and a stable epithelial phenotype. The population doubling time of Rca-T cells is 23.35 h. Approximately 39.8% of these cells are in S phase, and the apoptosis rate of Rca-T cells is 7.46%. Furthermore, in immunodeficient nude mice, both the xenograft rate and the incidence of experimental lung metastasis are 100%. The in vitro assays further reveal the highly malignant and epithelial-mesenchymal transition-like properties of Rca-T cells. CONCLUSION In this study, the tumorigenic and highly distant metastatic TSCC cell line Rca-T was established. The malignant features of this cell line, especially its metastatic potential, will enable a wealth of functional studies on the molecular mechanisms of TSCC metastasis in the future.

Abstract
BACKGROUND Head and neck cancer are one of the most common neoplasm pathologies in humans. The aim of this study was to analyze the type, characteristics, treatment and evolution of oral neoplasm or precancerous lesion in a sample of Andalusian population (Spain) derived from the Oncology Rehabilitation Hospital Unit during a period of 20 years. MATERIAL AND METHODS A retrospective descriptive study was carried out during the years 1991 and 2011 analyzing the type, characteristics, treatment and follow-up of oral neoplasm in the Oral and Maxillofacial Surgery Unit of the Universitary Hospital Virgen del Rocio. The inclusion criteria were patients whose underlying pathology was any type of benign or malignant neoplasm or presence of precancerous lesion that, after treatment, had been referred to the Prosthetic Rehabilitation Unit. RESULTS Of the initial analyzed sample of 60 patients, only 45 patients met the inclusion criteria. Of the final sample analyzed, 31 subjects were men (68.9%) and 14 women (31.1%) (p = 0.0169). The mean age of the sample was 57 years ± 13.83, been more frequently in older people with more than 50 years (73.3%) (p = 0.0169). The most common type of neoplasm was epidermoid carcinoma (64.4%). The site most frequently found in squamous cell carcinoma was the floor of the mouth (31%). The most frequent treatment modality was surgery with postoperative radiotherapy (42.2%). All patients had a minimum follow-up of 5 years, and a recurrence in this period was identified in 11.1% of the sample. Multivariate logistic regression showed a statistically significant association for the variables age (p = 0.0063) and smoking (p = 0.0434). CONCLUSIONS Epidermoid carcinoma is the most frequent tumor in the oral cavity, where increase age and smoking are confirmed as associated risk factors.

Abstract
Introduction Recent times have revealed an increase in incidence of Oral Squamous Cell Carcinoma (OSCC) in young adults including those who lack association with typical risk factors such as tobacco. There are reported variations in clinical behaviour of tumours in young and older individuals. Aim Present study evaluated differences in clinicopathological characteristics between two groups of OSCC, below and above 40 years of age. Materials and Methods An analytical study was performed on two groups of OSCC patients, below and above 40 years of age. Clinicopathological parameters of site distribution, type of habit, histological grade, nodal metastasis, margin status, mitotic index and Argyrophilic Nucleolar Organizing Regions (AgNOR) count were compared. Chi-square test and Students t- test were applied for statistical analysis. Results Present study revealed that mean AgNOR count was significantly higher in older group (6.38) than younger group (4.27). However, no significant differences were noted in site distribution, tobacco habit, histological grade, mitotic index, nodal metastasis and status of resected surgical margins between the two age groups. A trend for increased metastasis and poor histological differentiation was also observed in the older and younger age group respectively. Most common site was buccal mucosa followed by tongue in both groups. Conclusion Reasons for documented variability in tumour characteristics between young and older patients are currently unclear. Difference in AgNOR count found in present study is suggestive of variability in proliferative and ploidy characteristics between different age groups and supports the hypothesis of genetic and epigenetic influences in development of oral cancer.

Abstract
OBJECTIVE This study investigated the effect of RhoA silencing through RNA interference on proliferation and growth of tongue cancer cells, as well as explored the possible mechanisms of this effect. METHODS SSC-4 tongue cancer cells were cultured in vitro and then transfected with small interfering RNA to knock down RhoA expression. The tested cells were divided into three groups: experimental group (experimental group 1: transfected with RhoA-siRNA-1; experi-mental group 2: transfected with RhoA-siRNA-2), negative control group (transfected by random sequence NC-siRNA), and blank control group (transfected with Lipofectamine). The expression levels of RhoA mRNA were respectively measured by quantitative real-time polymerase chain reaction and western blot assay. Moreover, the expression levels of cyclin D1, p21, and p27 and RhoA protein were evaluated by Western blot assay. Proliferation and growth potentiality were analyzed through evaluation of doubling times and methyl thiazolyl tetrazolium assessment. RESULTS The expression levels of RhoA gene and protein of experimental groups significantly decreased following siRNA transfection compared with those in the negative and blank control groups. The expression of cyclin D1 decreased significantly and that of p21 and p27 increased significantly. The doubling time was extended and the growth potentiality decreased. CONCLUSIONS The results indicated that RhoA silencing can inhibit proliferation of tongue cancer cells, whereas RhoA affects cell proliferation by regulating the cell cycle pathway. Thus, RhoA is a potential target in gene therapy for tongue cancer.

Abstract
INTRODUCTION Pediatric head and neck Squamous cell carcinoma (PHNSCC) is a rare disease. The optimum treatment and outcome remains poorly understood because of rarity. METHODS We conducted an individual patient data analysis of PHNSCC. Two authors independently searched PubMed, google search, and Cochrane library for eligible studies using following search words: Pediatric Head and neck squamous cell carcinoma, Head and neck squamous cell carcinoma under age of 20, Head and neck squamous cell carcinoma in young, PHNSCC till June 1, 2016 published in English language. RESULTS Total of 217 patients of PHNSCC were found in the literature. Median age among the cohort was 15 years (Range: 0-20 years) with a clear male preponderance. Oral cavity tumors were commonest 75 (70%) followed by laryngeal neoplasms 16(15%). Median disease free survival was 9 months (Range: 0-216 months). Median overall survival was 48 months (Range: 1-216 months). In univariate analysis treatment modality had significant impact on disease free survival (DFS). Whereas, patients treated with Surgery, Laryngeal primary had significantly better OS. Patients with associated fanconis anemia had significantly worse overall survival (OS). CONCLUSION PHNSCC is a rare disease with poorer outcome. Associated DNA defects leads to poorer OS. Patients treated with surgery alone or surgery followed by adjuvant radiation had better DFS and OS. Molecular profiling and personalized therapy may improve survival with limited toxicity.

[PMID: 27876236 DOI: 10.1016/j.prp.2016.10.015] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/18/2016] [Revised: 10/18/2016] [Accepted: 10/28/2016] [Indexed: 12/30/2022]
Abstract
BACKGROUND Squamous cell carcinoma (SCC) of the oral cavity is a malignant epithelial tumor that most commonly involves the tongue, and mainly affects men between the fifth and seventh decades of life. This study compared the lymphatic vessel density and VEGF-C expression in SCCs of the tongue between young and old patients. METHODS Thirty-four SCCs of the tongue, 17 diagnosed in young patients (≤40y) and 17 diagnosed in old patients (>50y), were evaluated by immunohistochemistry. Lymphatic microdensity was determined based on the number of vessels immunoreactive to anti-D2-40 antibody. The percentage of neoplastic cells exhibiting cytoplasmic staining for VEGF-C was established for each case. RESULTS Assessment of intratumoral lymphatic microdensity (ILMD) disclosed a median number of 6.20 lymphatic vessels in young patients and of 6.60 in old patients (p=0.809). Analysis of peritumoral lymphatic microdensity (PLMD) revealed a median number of 3.60 lymphatic vessels in young patients and of 3.40 in old patients (p=0.769). In the tumor core, analysis of the percentage of immunopositive cells for VEGF-C revealed a median number of 95.95% in young patients and of 55.48% in old patients (p<0.001). In the deep invasive front, the median number of immunopositive cells for VEGF-C was 97.93% in young patients and 66.09% in old patients (p<0.001). CONCLUSIONS The results of this study suggest that the more aggressive biological behavior of SCC of the tongue in young patients may be related to a higher expression of VEGF-C.

Abstract
Background In recent years have been observed an increased incidence of OSCC in young individuals. Based on this, the aim this study was to describe the clinical characteristics of all cases of OSCC in younger patients, diagnosed in two oncology referral hospitals, at the northeast region of Brazil within a 12-year period. Material and Methods Data regarding general characteristics of patients (age, gender and tobacco and/or alcohol habits) and information about the lesions (tumor location, size, regional lymph node metastasis, distant metastasis and clinical stage) were submitted to descriptive and inferential analysis. Statistical analysis included Chi-square and Fisher’s exact tests (P<0.05). Results Out of 2311 registered cases of OSCC, 76 (3.3%) corresponded to OSCC in patients under 45 years old. Most of them were male (n=62, 81.6%) and tobacco and/or alcohol users (n=40, 52.8%). The most frequent site was the tongue (n=31, 40.8%), with predominance of cases classified at advanced clinical stage (III and IV, n = 46, 60.5%). The advanced stage of OSCC (III and IV) was statistically associated with male gender (P=0.035), lower education level (P=0.007), intraoral site(P<0.001), presence of pain symptomatology (P=0.006), and consumption of tobacco and/or alcohol (P=0.001). Conclusions The profile of OSCC in young patients resembles to the commonly characteristics reported for overall population. The late diagnosis in young patients usually results in poor prognosis, associated with gender, harmful habits and tumor location. Although prevalence is low, stimulus to prevention and to early diagnosis should be addressed to young individuals exposed to risk factors. Key words:Squamous cell carcinoma, head and neck neoplasms, risk factors, young patients, prognosis.

Abstract
N-a-Acetyltransferase 10 protein (Naa10p) is a potential prognostic biomarker and a modulator of several types of cancer. Despite the efforts to elucidate the relationship between Naa10p expression and clinical prognosis, little is known about its expression and role in human oral squamous cell carcinoma (OSCC). In this study, we firstly detected the mRNA and protein levels of Naa10p in 10 paired OSCC tissue samples and found Naa10p was frequently overexpressed in the tumor tissues of patients with OSCC. Further detection by immunohistochemistry was used to examine Naa10p expression in 124 OSCC tumor specimens by tissue microarray (TMA), and a relative high level of Naa10p protein expression was found in 98 out of 124 cases (79.03 %). Additional analyses illustrated that Naa10p expression inversely correlated with clinical stage (p = 0.047), degree of lymph node status (p = 0.020), differentiation (p = 0.022), and recurrence (p = 0.016) of patients with OSCC. The survival analysis showed that patients with Naa10p-positive expression had a better prognosis for disease-free survival (DFS) or overall survival (OS) than those with Naa10p-negative expression (p = 0.003 for both). Furthermore, we assessed the effect of Naa10p knockdown on motility of oral cancer cells in vitro, and the results showed that Naa10p inhibit cell wound healing, migration, and invasion. In summary, our study illustrated that the expression of Naa10p had a potential value for predicting the progression of OSCC and prognosis of OSCC patients.

Thymosin β4 induces proliferation, invasion, and epithelial-to-mesenchymal transition of oral squamous cell carcinoma. Amino Acids 2015; 48:117-27.

Abstract
The epithelial-to-mesenchymal transition (EMT) plays a vital role in carcinogenesis, invasion, and metastasis of many epithelial tumors including oral squamous cell carcinoma (OSCC), a common malignancy of the head and neck. However, the functional role of the actin-sequestering protein thymosin β4 (Tβ4) in the EMT in OSCCs remains unclear. Thus, we investigated whether overexpression of Tβ4 could induce in vitro tumorigenesis such as cell proliferation and anchorage independency and an EMT-like phenotype in OSCCs. Also, we examined whether it affects invasiveness and cell motility-associated signaling molecules. Tβ4-overexpressing OSCCs, SCC-15_Tβ4 and SCC-25_Tβ4, enhanced cell proliferation and colony formation. In addition, we observed that Tβ4 overexpression induced an EMT-like phenotype, accompanied by a decrease in expression of the epithelial cell marker E-cadherin and an increase in expression of mesenchymal cell markers vimentin and N-cadherin. Also, the expression level of Twist1, an EMT-inducing transcription factor, was significantly enhanced in SCC-15_Tβ4 and SCC-25_Tβ4 cells. Tβ4 overexpression augmented in vitro invasion and MMP-2 activity and enhanced the phosphorylation of paxillin and cortactin and expression of LIMK1. Taken together, these results suggest that Tβ4 overexpression could be one of the causes of tumorigenesis and progression in OSCCs. Further investigation on the Tβ4 molecule would encourage the development of specific targets for cancer treatment.

Abstract
BACKGROUND Oral tongue squamous cell carcinomas (TSCC) are a unique subset of head and neck cancers with a distinct demographic profile, where up to half of the cases are never smokers. A small proportion of patients with OSCC are known to respond to EGFR TKI. We used a high-sensitivity mass spectrometry-based mutation profiling platform to determine the EGFR mutation status, as well as other actionable alterations in a series of Asian TSCC. METHODS 66 TSCC patients treated between 1998-2009 with complete clinico-pathologic data were included in this study. Somatic mutation profiling was performed using Sequenom LungCarta v1.0, and correlated with clinical parameters. RESULTS Mutations were identified in 20/66(30.3%) of samples and involved TP53, STK11, MET, PIK3CA, BRAF and NRF2. No activating EGFR mutations or KRAS mutations were discovered in our series, where just over a third were never smokers. The most common mutations were in p53 (10.6%; n = 7) and MET (10.6%, n = 11) followed by STK11 (9.1%, n = 6) and PIK3CA (4.5%, n = 3). BRAF and NRF2 mutations, which are novel in TSCC, were demonstrated in one sample each. There was no significant correlation between overall mutation status and smoking history (p = 0.967) or age (p = 0.360). Positive MET alteration was associated with poorer loco-regional recurrence free survival (LRFS) of 11 months [vs 90 months in MET-negative group (p = 0.008)]. None of the other mutations were significantly correlated with LRFS or overall survival. Four of these tumors were propagated as immortalized cell lines and demonstrated the same mutations as the original tumor. CONCLUSIONS Using the Sequenom multiplexed LungCarta panel, we identified mutations in 6 genes, TP53, STK11, MET, PIK3CA, BRAF and NRF2, with the notable absence of EGFR and HER2 mutations in our series of Asian OSCC. Primary cell line models recapitulated the mutation profiles of the original primary tumours and provide an invaluable resource for experimental cancer therapeutics.

Tumour Biol 2014; 35:8801-11.

Abstract
Pituitary tumor-transforming gene 1 (PTTG1) is an important oncogenic transcription factor implicated in various malignancies, including oral squamous cell carcinoma (OSCC), a common malignancy of head and neck. Although PTTG1 is reportedly overexpressed in OSCC tissues, its role in human OSCC remains elusive. Thus, this study was conducted to explore the correlation between PTTG1 expression and tumorigenesis of OSCC. We first examined PTTG1 mRNA and protein expression in 28 pairs of OSCC tissues and adjacent non-tumor tissues. PTTG1 protein levels in 98 OSCC specimens were also evaluated by using immunohistochemistry. Our data showed that both mRNA and protein expression levels of PTTG1 in OSCC tissue specimens were markedly higher than that in the corresponding non-tumor tissue samples. A high level of PTTG1 protein expression was found in 74 out of 98 cases (75.51 %) and it was correlated with lymph node metastasis (P = 0.002) and tumor-node-metastasis (TNM) stage (P = 0.007) of patients with OSCC. Moreover, forced overexpression of PTTG1 enhanced SCC15 cell migration and invasion, whereas knockdown of PTTG1 resulted in reverse phenomena. In addition, elevated PTTG1 also increased the activities and expressions of matrix metalloproteinase (MMP)-2, and enhanced epithelial-mesenchymal-transition (EMT) process in SCC15 cells. The EMT changes were accompanied by downregulation of epithelial cadherin (E-cadherin) protein expression and upregulation of snail and vimentin. In summary, our results illustrate that PTTG1 may contribute to the development and progression of human OSCC.
