Abstract
BACKGROUND The anterolateral thigh (ALT) perforator flap is a workhorse flap for tongue reconstruction. The authors present an alternative option using the profunda artery perforator (PAP) flap for glossectomy reconstruction compared with the ALT flap. METHODS A retrospective review was conducted of 65 patients who underwent subtotal or total glossectomy reconstruction between 2016 and 2020 (46 ALT versus 19 PAP flaps). Flap volume was assessed using computed tomography scans at two different time points. Quality of life and functional outcomes were measured using the MD Anderson Symptom Inventory for Head and Neck Cancer. RESULTS Patients receiving a PAP flap had significantly lower body mass index compared with those receiving an ALT flap (22.7 ± 5.0 versus 25.8 ± 5.1; P = 0.014). Donor-site and recipient-site complications were similar, as was the mean flap volume 7 months after surgery (30.9% for ALT versus 28.1% for PAP; P = 0.93). Radiation and chemotherapy did not appear to have a significant effect on flap volume change over time. The most frequently reported high-severity items in MD Anderson Symptom Inventory for Head and Neck Cancer were swallowing/chewing and voice/speech for both cohorts. Patients who had reconstruction with a PAP flap had significantly better swallowing function ( P = 0.034). CONCLUSIONS Both the PAP and ALT flaps appear to be safe and effective choices for subtotal and total tongue reconstruction. The PAP flap can serve as an alternative donor site, especially in patients with low body mass index and thin lateral-thigh thickness undergoing reconstruction of extensive glossectomy defects. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, III.

Targeting notch-related lncRNAs in cancer: Insights into molecular regulation and therapeutic potential. Pathol Res Pract 2024; 257:155282. [PMID: 38608371 DOI: 10.1016/j.prp.2024.155282] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/15/2024] [Revised: 03/29/2024] [Accepted: 03/30/2024] [Indexed: 04/14/2024]
Abstract
Cancer is a group of diseases marked by unchecked cell proliferation and the ability for the disease to metastasize to different body areas. Enhancements in treatment and early detection are crucial for improved outcomes. LncRNAs are RNA molecules that encode proteins and have a length of more than 200 nucleotides. LncRNAs are crucial for chromatin architecture, gene regulation, and other cellular activities that impact both normal growth & pathological processes, even though they are unable to code for proteins. LncRNAs have emerged as significant regulators in the study of cancer biology, with a focus on their intricate function in the Notch signaling pathway. The imbalance of this pathway is often linked to a variety of malignancies. Notch signaling is essential for cellular functions like proliferation, differentiation, and death. The cellular response is shaped by these lncRNAs through their modulation of essential Notch pathway constituents such as receptors, ligands, and downstream effectors around it. Furthermore, a variety of cancer types exhibit irregular expression of Notch-related lncRNAs, underscoring their potential use as therapeutic targets and diagnostic markers. Gaining an understanding of the molecular processes behind the interaction between the Notch pathway and lncRNAs will help you better understand the intricate regulatory networks that control the development of cancer. This can open up new possibilities for individualized treatment plans and focused therapeutic interventions. The intricate relationships between lncRNAs & the Notch pathway in cancer are examined in this review.

Abstract
Laminin subunit alpha 3 (LAMA3) is a cancer regulator. However, its effects and regulatory pathways in oral squamous cell carcinoma (OSCC) progression remain unknown. This research aimed to determine the influence of LAMA3 regulation via methyltransferase-like 3 (METTL3) on OSCC progression. Using quantitative real-time polymerase chain reaction and bioinformatics analysis, the expression levels of LAMA3 and METTL3 in OSCC tissues were examined. The functional roles of LAMA3 and METTL3 were analyzed using cell functional experiments. Using methylated RNA immunoprecipitation and mRNA stability assays, LAMA3 and METTL3 regulation was investigated. In OSCC tissues, LAMA3 was upregulated. LAMA3 inhibition hampered OSCC cell proliferation, invasion, and migration while its overexpression facilitated OSCC cell progression. METTL3 serves as a crucial upstream regulator of LAMA3 in OSCC and upregulates LAMA3 expression via an m6A-dependent mechanism. The low METTL3 expression partially restored the enhanced malignant phenotype induced by LAMA3 overexpression. Our findings indicate that METTL3 and LAMA3 act as pro-oncogenic factors in OSCC, with METTL3 promoting OSCC malignancy via m6A modification-dependent stabilization of LAMA3 transcripts, representing a novel regulatory mechanism in OSCC.

Abstract
Oral cancer (OC), characterized by malignant tumors in the mouth, is one of the most prevalent malignancies worldwide. Chemotherapy is a commonly used treatment for OC; however, it often leads to severe side effects on human bodies. In recent years, nanotechnology has emerged as a promising solution for managing OC using nanomaterials and nanoparticles (NPs). Nano-drug delivery systems (nano-DDSs) that employ various NPs as nanocarriers have been extensively developed to enhance current OC therapies by achieving controlled drug release and targeted drug delivery. Through searching and analyzing relevant research literature, it was found that certain nano-DDSs can improve the therapeutic effect of drugs by enhancing drug accumulation in tumor tissues. Furthermore, they can achieve targeted delivery and controlled release of drugs through adjustments in particle size, surface functionalization, and drug encapsulation technology of nano-DDSs. The application of nano-DDSs provides a new tool and strategy for OC therapy, offering personalized treatment options for OC patients by enhancing drug delivery, reducing toxic side effects, and improving therapeutic outcomes. However, the use of nano-DDSs in OC therapy still faces challenges such as toxicity, precise targeting, biodegradability, and satisfying drug-release kinetics. Overall, this review evaluates the potential and limitations of different nano-DDSs in OC therapy, focusing on their components, mechanisms of action, and laboratory therapeutic effects, aiming to provide insights into understanding, designing, and developing more effective and safer nano-DDSs. Future studies should focus on addressing these issues to further advance the application and development of nano-DDSs in OC therapy.

Abstract
Background Photodynamic therapy (PDT) has emerged as a promising strategy for oral cancer treatment. Verteporfin is a powerful photosensitizer and widely used in the treatment of macular degeneration. However, rare work has reported its potential in the treatment of oral cancer. Methods In this study, we introduce an innovative approach of nano-photosensitizer based on Verteporfin, which was prepared by utilizing macrophage membrane to coat Verteporfin-loaded zeolitic imidazolate framework 8 (ZIF-8) for effective photodynamic therapy against oral cancer. Nanoparticle characteristics were assessed including size, zeta potential, and PDI. Cellular uptake studies were conducted using CAL-27 cells. Furthermore, inhibitory effects in both in vitro and in vivo settings were observed, ensuring biosafety. Assessment of anticancer efficacy involved tumor volume measurement, histological analyses, and immunohistochemical staining. Results In vitro experiments indicated that the nano-photosensitizer showed efficient cellular uptake in the oral cancer cells. Upon the laser irradiation, the nano-photosensitizer induced the generation of reactive oxygen species (ROS), leading to cancer cell apoptosis. The in vivo experiments indicated that the coating with cell membranes enhanced the circulation time of nano-photosensitizer. Moreover, the specificity of the nano-photosensitizer to the cancer cells was also improved by the cell membrane-camouflaged structure in the tumor-bearing mouse model, which inhibited the tumor growth significantly by the photodynamic effect in the presence of laser irradiation. Conclusion Overall, our findings demonstrate the potential of macrophage membrane-coated ZIF-8-based nanoparticles loaded with Verteporfin for effective photodynamic therapy in oral cancer treatment. This nano-system holds promise for synergistic cancer therapy by combining the cytotoxic effects of PDT with the activation of the immune system, providing a novel therapeutic strategy for combating cancer.

Cancers (Basel) 2023; 15:cancers15061885. [PMID: 36980773 PMCID: PMC10047362 DOI: 10.3390/cancers15061885] [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: 02/06/2023] [Revised: 03/17/2023] [Accepted: 03/19/2023] [Indexed: 03/30/2023] Open
Abstract
BACKGROUND Flap reconstruction is commonly used in advanced tongue carcinoma in order to compensate for the loss of tongue tissue and function. Surprisingly, a large number of reconstructed early-stage tongue cancer can be found. Survival or functional benefits in these cases remain unclear. METHODS A retrospective data analysis of 384 surgically treated tongue carcinoma patients was conducted aiming to find epidemiologic and survival differences between patients with (n = 158) or without flap reconstruction (n = 226). A prospective functional analysis was performed on 55 early-stage tongue cancer patients, 33 without and 22 with radial-forearm flap reconstruction, focusing on post-therapeutic swallowing function as the primary endpoint, speech as the secondary endpoint, xerostomia, quality of life, and mouth opening. RESULTS Consistent with the current literature, we demonstrated the significantly more frequent use of flap grafts in advanced tongue carcinomas. For the first time, we depicted a higher female ratio in the reconstructed group (p = 0.02). There were no significant differences in survival or functional outcomes between the groups. The none-reconstructed group showed more frequent use of adjuvant C/RT despite presenting fewer N+ stages. CONCLUSIONS The higher female ratio in the reconstruction group is plausible due to the anatomically smaller oral cavity and relatively larger carcinoma in women. A higher presence of close margins in the none-reconstruction group may explain the more frequent use of adjuvant C/RT. Since we found no survival or functional differences between the groups, we propose a critical approach toward flap reconstruction in T1/2 tongue carcinoma. At the same time, proportional aspects and adequate resection margins should be taken into account.

Abstract
Oral squamous cell carcinoma (OSCC) is one of the most common oral malignancies. Radiotherapy is the primary noninvasive treatment of OSCC for avoiding surgery-induced facial deformities and impaired oral function. However, the specificity of in situ OSCC limits radiotherapeutic effects because of the hypoxia-induced low radiosensitivity of tumors and the low radiation tolerance of surrounding normal tissues. Here, we design a highly efficient and low-toxic radiosensitization strategy. On the one hand, biocompatible poly(vinyl pyrrolidone)-modified tantalum nanoparticles (Ta@PVP NPs) not only have strong X-ray deposition capability to upregulate oxidative stress but also have photothermal conversion efficiency to improve hypoxia for tumor radiosensitivity. On the other hand, to optimize the spatial distribution of Ta@PVP NPs within tumors, mussel-inspired catechol with bioadhesive properties is grafted on tumor microenvironment-responsive sodium alginate (DAA) to form in situ hydrogels for precision radiotherapy. On this basis, we find that Ta@PVP-DAA hydrogels effectively inhibit OSCC development in mice under photothermal-assisted radiotherapy without facial deformities and damage to surrounding normal tissues. Overall, our work not only promotes the exploration of Ta@PVP NPs as new radiosensitizers for OSCC but also develops a nanocomposite hydrogel system strategy as a promising paradigm for the precision treatment of orthotopic tumors.

Abstract
BACKGROUND Anterolateral thigh (ALT) and Radial forearm free flaps (RFFF) are historically the most common methods of oral reconstruction. The Superficial circumflex iliac artery perforator flap (SCIP) is an alternative providing a donor site that can be readily closed primarily with improved cosmesis in younger patients, due to its concealability. METHODS We reviewed 135 patients who received ALT, RFFF or SCIP flaps for oral reconstruction in our institution. Our aim was to compare operative and perioperative outcomes between each cohort. ANOVA and χ2 test were used for statistical analysis. RESULTS There were 37 ALT, 64 RFFF and 35 SCIP reconstructions. Patients reconstructed with SCIP flaps had smaller resection volumes (P < 0.001) and earlier T and N classifications (P = 0.001, P = 0.008), and consequently reduced tracheostomy rates (P < 0.001), reduced need for enteral feeding at discharge (P < 0.001) and shorter length of stay and perioperative times (P < 0.001). SCIP flaps were more common in younger patients (P < 0.01). ALT flaps were used for more advanced disease (P = 0.001) and had larger resection volumes (P < 0.001) and increased need for assisted enteral feeding (P < 0.001). There were no significant differences in flap or donor site outcomes. There were two flap failures, both RFFF. CONCLUSION Each flap plays an important role in the reconstruction of oral defects, with larger defects preferentially reconstructed with ALT flaps. SCIP appears to be a reliable alternative in small defects with excellent perioperative and postoperative outcomes.

Establishment of a Prognostic Nomogram for Cancer-Specific Survival in Patients With Base-of-Tongue Squamous Cell Carcinoma: A Retrospective Study Based on the SEER Database. Cancer Control 2023; 30:10732748231210733. [PMID: 37969067 PMCID: PMC10655788 DOI: 10.1177/10732748231210733] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2023] [Revised: 07/16/2023] [Accepted: 10/02/2023] [Indexed: 11/17/2023] Open
Abstract
BACKGROUND The aim of this retrospective study was to construct and clinically apply a nomogram for cancer-specific survival (CSS) in patients diagnosed with base-of-tongue squamous cell carcinoma (BOTSCC) to predict their survival prognosis. METHODS We collected 8448 patients diagnosed with BOTSCC during 2004-2015 from the Surveillance, Epidemiology, and End Results (SEER) database and divided 30% and 70% of them into validation and training cohorts, respectively. We utilized backward stepwise regression in the Cox model to select variables. Predictive variables were subsequently identified from the variables selected above by using multivariate Cox regression. The new survival model was compared with the American Joint Committee on Cancer (AJCC) prognosis model using the following variables: calibration curve, time-dependent area under the receiver operating characteristic curve (AUC), concordance index (C-index), integrated discrimination improvement (IDI), decision-curve analysis (DCA), and net reclassification improvement (NRI). RESULTS A nomogram was established for predicting the CSS probability in patients with BOTSCC. Factors including sex, race, age at diagnosis, marital status, radiotherapy status, chemotherapy status, TNM AJCC stage, surgery status, tumor size, and months from diagnosis to treatment were selected through multivariate Cox regression as independent predictors of CSS. Calibration plots indicated that the model we established had satisfactory calibration ability. The AUC, C-index, IDI, DCA, and NRI results illustrated that the nomogram performed explicit prognoses more accurately than did the AJCC system alone. CONCLUSION We identified the relevant factors affecting the survival of BOTSCC patients and analyzed the data on patients suffering from BOTSCC in the SEER database. These factors were used to construct a new nomogram to give clinical staff a more-visual prediction model for the 3-, 5-, and 8-year probabilities of CSS for patients newly diagnosed with BOTSCC, thereby aiding clinical decision making.

Eugenol Induces Apoptosis in Tongue Squamous Carcinoma Cells by Mediating the Expression of Bcl-2 Family. LIFE (BASEL, SWITZERLAND) 2022; 13:life13010022. [PMID: 36675971 PMCID: PMC9861585 DOI: 10.3390/life13010022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/25/2022] [Revised: 12/16/2022] [Accepted: 12/19/2022] [Indexed: 12/24/2022]
Abstract
Head and neck squamous cell carcinoma is highly aggressive type of cancer for which the available treatment often causes patients severe side effects. Eugenol (Eug) is the major active constituent of clove essential oil and is known to possess antitumor properties. The present study aimed to assess the in vitro cytotoxicity of eugenol in SCC-4, tongue squamous carcinoma cells, and also in HGF, human gingival fibroblasts. Both cell lines were treated with five concentrations of Eug (0.1-1 mM) for 72 h. Cellular viability was assessed, followed by cellular morphological evaluation and by staining of the nuclei and cytoskeleton. RT-PCR was conducted in order to find the effect eugenol had on the expression on Bad, Bax, and Bcl-2 genes. Eugenol induced a dose-dependent decrease in viability in both cell lines, with the SCC-4 cells being significantly more affected. HGF cells detached from the plate at the highest concentrations used, while SCC-4 cells changed their morphology in a dose-dependent manner, with rounding, floating cells, and confluency loss being observed. Apoptotic-like signs such as chromatin and actin filaments condensation were clearly seen in SCC-4 cells, while RT-PCR revealed a significantly increased expression of pro-apoptotic genes Bax and Bad. Therefore, eugenol exerts its cytotoxic effect in tongue squamous cell carcinoma through inducing apoptosis.

Abstract
The purpose of the study was to assess and compare the quality of speech and swallowing between three reconstruction options (primary closure-group A, secondary intention healing-group B and flap reconstruction-group C), in small to moderate sized onco-surgical defects of oral tongue. 47 patients fulfilled the eligibility criteria during the study period, of which, 15 belonged to group A, 16 belonged to group B, 16 were in group C. Speech and swallowing assessment was done using Speech Intelligibility Assessment score and MD Anderson Dysphagia Inventory, respectively. The above tests were administered pre-operatively, 1 month and 6 months post-operativey in all the study participants. The average scores of speech intelligibility at 1 month were 66.13% (±19.96), 70.04% (±12.28) and 37.31% (±11.29) for groups A, B and C respectively. Similarly, average long term scores for speech intelligibility in these three groups were 72.7% (±17.72), 83.3% (±12.78) and 52.8% (±11.74) respectively. With regards to swallowing the composite scores at 1 month were 73.67 (±13.69), 68.31 (±16.06) and 41.81 (±5.44), and at 6 months were 83.2 (±10.24), 79.31 (±12.29) and 57.88 (±7.37), respectively for groups A, B and C. All the differences were statistically significant (p < 0.05). Healing by secondary intention offered the best functional outcome in terms of speech intelligibility, and primary closure offered best swallowing outcomes in operated cases of oral tongue. This trial has been registered with the Clinical Trials Registry-India in December 2018 (CTRI Reg. No: CTRI/2018/12/016803).

Abstract
Extracellular vesicles (EVs), nano-sized bilayer membrane structures containing lipids, proteins and nucleic acids, play key roles in intercellular communication. Compared to stem cells, EVs have lower tumorigenicity and immunogenicity, are easier to manage and cause fewer ethic problems. In recent years, EVs have emerged as a potential solution for tissue regeneration in stomatology through cell-free therapies. The present review focuses on the role of EVs in dental and maxillofacial tissue repair and regeneration, including in dental and periodontal tissue, maxilla and mandible bone, temporomandibular joint cartilage, peripheral nerve and soft tissue. We also make a brief overview on the mechanism of EVs performing functions. However, limitations and challenges in clinical application of EVs still exist and should be addressed in future researches.

Abstract
INTRODUCTION Partial glossectomy and reconstruction strategy for malignant tongue tumors influences speech and swallowing. OBJECTIVE The aim of this retrospective study was to evaluate long-term functional outcomes after partial glossectomy for pT2 mobile tongue carcinomas with a maximum dimension between 2 and 3cm. Different reconstruction strategies (with or without pedicled flap) were compared. METHODS Twenty-two patients with at least 12 months followup were included. Clinician-based and self-reported instruments were used to analyze tongue motility, speech intelligibility and articulation, swallowing, and quality of life. RESULTS Patients with a higher tongue motility had better articulation and lower dysphagia. Avoiding pedicled flap reconstruction seemed to guarantee lower impairment of speech and swallowing. Worse functional outcomes induced a lower quality of life. CONCLUSION Partial glossectomy results in tongue motility impairment and consequently alterations of oral functions. Since the type of reconstruction impacts long-term outcomes, it should be adequately planned before surgery.

Abstract
PURPOSE OF REVIEW Transoral robotic surgery (TORS) has experienced an evolution in recent years. This technique has proved to be a safe and effective method for extirpation of select oropharyngeal tumors. Advances in technology as well as improved surgeon experience allow for the resection of larger, more complex cancers. Although healing by secondary intention remains the current standard for limited oropharyngeal defects, larger resections demand reconstruction with vascularized tissue to minimize morbidity and optimize functional outcomes. The objective of this review is to evaluate recent literature regarding oropharyngeal reconstruction after TORS. RECENT FINDINGS A variety of reconstructive options to manage oropharyngeal defects exist. Several reconstructive algorithms have been suggested; however, careful consideration must be used to select the most ideal flap type. Locoregional flaps have shown excellent functional outcomes with limited morbidity. An increase in free flap reconstruction has been demonstrated, particularly among patients with larger TORS defects and following chemoradiation therapy. Despite limited data, robotic-assisted flap inset and microvascular anastomosis has recently shown promise. SUMMARY Reconstruction and flap selection following TORS should be tailored to the patient and unique oropharyngeal defect. Functional outcomes are promising with low complication rates among these patients.

Abstract
Oral squamous cell carcinoma (OSCC) is one of the top 15 most prevalent cancers worldwide. However, the current treatment models for OSCC (e.g., surgery, chemotherapy, radiotherapy, and combination therapy) present several limitations: damage to adjacent healthy tissue, possible recurrence, low efficiency, and severe side effects. In this context, nanomaterial-based photothermal therapy (PTT) has attracted extensive research attention. This paper reviews the latest progress in the application of biological nanomaterials for PTT in OSCC. We divide photothermal nanomaterials into four categories (noble metal nanomaterials, carbon-based nanomaterials, metal compounds, and organic nanomaterials) and introduce each category in detail. We also mention in detail the drug delivery systems for PTT of OSCC and briefly summarize the applications of hydrogels, liposomes, and micelles. Finally, we note the challenges faced by the clinical application of PTT nanomaterials and the possibility of further improvement, providing direction for the future research of PTT in OSCC treatment.

Abstract
Tongue squamous cell carcinoma (TSCC) is characterized by a poor prognosis and its 5‑year overall survival rate has not improved significantly. However, the precise molecular mechanisms underlying TSCC remain largely unknown. Through RNA screening, the present study identified a novel long noncoding RNA (lncRNA), keratin 16 pseudogene 6 (lncKRT16P6), which was upregulated in TSCC tissues and cell lines and associated with TSCC tumor stage and differentiation grade. Inhibition of lncKRT16P6 expression reduced TSCC cell migration, invasion and proliferation. lncKRT16P6 sponged microRNA (miR)‑3180 and upregulated GATA zinc finger domain containing 2A (GATAD2A) expression. miR‑3180 inhibition reversed the lncKRT16P6 depletion‑induced attenuation of TSCC malignancy and GATAD2A depletion reversed the miR‑3180 silencing‑induced enhancement of TSCC malignancy. In summary, the present study revealed a potential competitive endogenous RNA (ceRNA) regulatory pathway in which lncKRT16P6 modulates GATAD2A expression by binding miR‑3180, ultimately promoting tumorigenesis and metastasis in TSCC. Therefore, lncKRT16P6 may be used as a prognostic biomarker and therapeutic target for clinical intervention in TSCC.

Abstract
Reconstructive surgery in the management of head and neck cancer has evolved to include structure-specific approaches in which organ-specific treatment algorithms help optimize outcomes. Tongue cancer management and reconstruction are surgical challenges for which well-executed reconstructive plans should be completed promptly to avoid delaying any subsequently planned oncologic treatment. Crucial considerations in tongue cancer resection are the significant functional morbidity associated with surgical defects, particularly in terms of speech and swallowing, and the consequent negative impact on patients’ quality of life. With the evolution of microsurgical techniques and the development of the perforator flap concept, flap options can be tailored to the characteristics of various tongue defects. This has allowed the implementation of pliable flaps that can help restore tongue mobility and yield subsequent functional outcomes. Using an evolutional framework, we present this series of reviews related to tongue reconstruction. The first part of the review summarizes flap options and flap-related factors, such as volume and tissue characteristics. Related functional aspects are also presented, including tongue mobility, speech, and swallowing, as well as ways to evaluate and optimize these outcomes.

Abstract
BACKGROUND Embedded foreign bodies in the tongue are rarely seen in clinical settings. An untreated foreign body can cause a granuloma which often presents as an enlarged tongue mass. However, if foreign body ingestion status is unknown, physical examination and magnetic resonance imaging (MRI) tend to lead to suspicion of tongue cancer, especially in older patients. Thus, differential diagnosis of an enlarged tongue mass is important, especially because it is closely related to the choice of treatment method.
CASE SUMMARY A 61-year-old woman was admitted to the hospital with pain and noticeable swelling in the tongue that had persisted for over 1 mo. She had no previous medical history. MRI revealed abnormal signal intensities that were indicative of a neoplasm. Thus, the oral surgeon and radiologist arrived at a primary diagnosis of tongue cancer. The patient visited the Ear Nose and Throat Department for further consultation and underwent an ultrasound examination of the tongue. The ultrasonography was consistent with a linear hyperechoic foreign body which was indicative of an embedded foreign body (bone) in the tongue, even though the patient denied any history of foreign body ingestion. Complete surgical enucleation of the lesion was conducted. The mass which included a fish bone was completely removed. The post-operative pathological examination confirmed that the mass was a granuloma containing collagen fibers, macrophages and chronic inflammatory cells. The patient recovered without complications over a 2 mo follow-up period.
CONCLUSION We report a rare case of foreign body granuloma in the tongue that was primarily diagnosed as tongue cancer. The MRI and ultrasound examinations revealed a piece of bone in the left lateral aspect of the tongue. The granuloma, which contained a fish bone, was completely removed via surgery and confirmed via biopsy. Differential diagnosis of the enlarged tongue mass was critical to the selection of treatment method.

Abstract
Various abnormalities of the tongue, including cancers, commonly require surgical removal to sequester growth and metastasis. However, even minor resections can affect functional outcomes such as speech and swallowing, thereby reducing quality of life. Surgical resections alone create volumetric muscle loss whereby muscle tissue cannot self-regenerate within the tongue. In these cases, the tongue is reconstructed typically in the form of autologous skin flaps. However, flap reconstruction has many limitations and unfortunately is the primary option for oral and reconstructive surgeons to treat tongue defects. The alternative, but yet undeveloped strategy for tongue reconstruction is regenerative medicine, which widely focuses on building new organs with stem cells. Regenerative medicine has successfully treated many tissues, but research has inadequately addressed the tongue as a vital organ in need of tissue engineering. In this review, we address the current standard for tongue reconstruction, the cellular mechanisms of muscle cell development, and the stem cell studies that have attempted muscle engineering within the tongue. Until now, no review has focused on engineering the tongue with regenerative medicine, which could guide innovative strategies for tongue reconstruction.

Abstract
Tongue squamous cell carcinoma (TSCC) is one of the most common malignant tumor types in the oral and maxillofacial region. The etiology and pathogenesis behind TSCC is complicated. In the present study, three gene expression profiles, namely GSE31056, GSE13601 and GSE78060, were downloaded from the Gene Expression Omnibus (GEO). The GEO2R online tool was utilized to identify differentially expressed genes (DEGs) between TSCC and normal tissue samples. Furthermore, a protein-protein interaction (PPI) network was constructed and hub genes were validated and analyzed. A total of 83 common DEGs were obtained in three datasets, including 48 upregulated and 35 downregulated genes. Pathway enrichment analysis indicated that DEGs were primarily enriched in cell adhesion, extracellular matrix (ECM) organization, and proteolysis. A total of 63 nodes and 218 edges were included in the PPI network. The top 11 candidate hub genes were acquired, namely plasminogen activator urokinase (PLAU), signal transducer and activator of transcription 1, C-X-C motif chemokine ligand 12, matrix metallopeptidase (MMP) 13, secreted phosphoprotein 1 (SPP1), periostin, MMP1, MMP3, fibronectin 1 (FN1), serpin family E member 1 and snail family transcriptional repressor 2. Overall, 83 DEGs and 11 hub genes were screened from TSCC and normal individuals using bioinformatics and microarray technology. These genes may be used as diagnostic and therapeutic biomarkers for TSCC. In addition, SPP1 and FNl were identified as potential biomarkers for the progression of TSCC.

[PMID: 34440964 PMCID: PMC8401490 DOI: 10.3390/medicina57080758] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/17/2021] [Revised: 07/23/2021] [Accepted: 07/25/2021] [Indexed: 11/16/2022]
Abstract
Backgroundand Objectives: The reconstruction of tongue defects after cancer resection is challenging for reconstructive surgeons. The facial artery musculomucosal (FAMM) flap and the myomucosal buccinator flap (Bozola flap) are important tools in the reconstruction of intraoral defects. In this study, we describe the combination of both flaps—the extended, double-pedicled FAMM (dpFAMM) flap—and present clinical results of the reconstruction of moderate tongue defects in edentulous patients. Materials and Methods: a tongue defect, after squamous cell carcinoma excision, was reconstructed with the dpFAMM flap in 5 patients. Most of them received postoperative radiotherapy. Results: the healing process was uneventful in all patients. We did not observe flap necrosis or venous congestion. Tongue mobility, speech and swallowing were satisfactory. Conclusions: In conclusion, the dpFAMM flap is a good alternative in the reconstruction of moderate defects of the lateral part of the tongue. The flap is easy to harvest and has a good vascularity. This is a predictable method of reconstruction, especially for elderly patients with numerous comorbidities.

Abstract
Primary treatment of most oromaxillofacial tumors in dogs and cats is resective surgery. Management of malignant tumors may be very challenging as wide/radical free-margin surgical removal must be achieved while preserving vital functions. Removal of orofacial tumors may result in large defects exposing the oral cavity or creating a communication with the nasal, pharyngeal, or orbital cavities. Such defects require orofacial reconstruction in order to restore respiratory and manducatory functions. The veterinary surgeon must be familiar with reconstructive techniques in order to prevent the inability of closing the defect, which could lead to an insufficient resection. Small oral defects exposing the nasal cavity are best closed with local random mucosal flaps. Closure of large oral defects may be better achieved with a facial or major palatine-based axial-pattern flap. Small to moderate facial defects can be closed with local advancement or transposition skin flaps. Reconstruction of large facial defects often requires the use of locoregional axial pattern flaps such as the caudal auricular, the superficial temporal, or the facial (angularis oris) myocutaneous axial pattern flaps. Recent publications have shown that the facial (angularis oris) flap is a very versatile and reliable flap in orofacial reconstructive surgery. A surgical decision algorithm based on the size, nature, and location of the defect is proposed.

Abstract
Surgical excision is the main choice for tongue cancer treatment. However, the physiological functions of oral and maxillofacial regions might be severely impaired and high risk of tongue tumor recurrence cannot be avoided. It is thus becoming urgently important to develop alternative strategies for tongue cancer therapy. In this regard, a new class of near-infrared (NIR) light-responsive and peritumoral injectable hydrogel is fabricated with extraordinary photothermal therapy (PTT) for in situ tongue tumors. The as-prepared soft material exhibits good biocompatibility and ultra-strong photothermal effect due to the formed network by negatively charged proteins, chitosan molecules, and Ag3 AuS2 nanoparticles (NPs). In a well-constructed in situ tongue tumor model, tumors can be efficiently eradicated by one-time PTT treatment. Importantly, there are no side effects on surrounding normal tissues and potential tumor recurrence is inhibited. In stark contrast to traditional surgical excision, such biomaterials hold great potential for clinical treatment of oral cancers.

Volume and location of the defect as predictors of speech outcome after glossectomy: correlation with a classification. Int J Oral Maxillofac Surg 2021; 50:1533-1539.

Abstract
The evaluation of speech outcomes after resection and reconstruction of the oral tongue remains largely unsystematic. A cross-sectional study was performed to analyse the speech outcomes of patients who underwent curative treatment with appropriate reconstruction. Sixty-nine patients were assessed for speech intelligibility and phonetics using a validated speech intelligibility assessment tool in the local language. Volume defects were classified as class I (less than one third), II (one third to half), III (half to two-thirds), or IV (two-thirds to total glossectomy). Defect location was defined as lateral, tip, or sulcus. The χ2 test and Kruskal-Wallis test were used to test volume and location as predictors. Twenty-six patients had class I defects, 29 had class II defects, seven had class III defects, and seven had class IV defects. Twenty-two patients (31.9%) received adjuvant radiotherapy. Mean vowel, consonant, word, and paragraph intelligibility were 99.27%, 86.86%, 85.52%, and 88.72%, respectively. The incremental volume of the glossectomy defect was significantly correlated with speech intelligibility scores and phonatory alterations. In classes II and III, tip resection significantly affected interdental sounds. All patients in class III had affected alveolar and alveo-palatal sounds. The results positively corroborated the volume and location of the glossectomy defect to a classification system.

Abstract
This study aimed to characterize the swallowing outcomes after glossectomy and analyze factors affecting them. An attempt is made to propose a classification system and corroborate it to the results. This is a cross-sectional study to assess swallowing in carcinoma tongue patients treated surgically with or without reconstruction, followed by adjuvant therapy as indicated. One hundred and six patients were evaluated with videofluoroscopy (VFS). Volume defects were classified as I: less than one-third, II: one-third to half, III: half to two-thirds, IV: two-thirds to total glossectomy. Location was assigned as lateral, tip, and sulcus defects. Predictors were T stage, surgical approach, volume, location, and adjuvant radiotherapy. Chi-square and logistic regression were used for statistical analysis. Defects were Class I, II, III, and IV in 36, 42, 16, and 12 patients, respectively. Adjuvant radiotherapy was given in 40% of cases. Mean evaluation time was 14 months from treatment. On, Functional Oral Intake Scale (FOIS) score, as the Class of the defect increased, the percentage of patients with low scores (poor swallowing outcomes) showed an increasing trend (p < 0.001). Defect volume, T stage, approach, and radiotherapy correlated significantly with an abnormality of all VFS parameters (p < 0.001). On multivariate analysis, defect volume remained an independent predictor for oral parameters; radiotherapy emerged as the only independent predictor for pharyngeal parameters. The incremental volume of the defect is a significant independent predictor of swallowing. Based on this, we propose a classification for glossectomy.

Abstract
Although many algorithms exist to classify oral cavity defects, they are limited by either considering a single subsite or failing to provide a concise reconstructive algorithm for the breadth of defects. Based upon our experience as a tertiary referral center, a unifying algorithm is presented that guides free flap selection in this heterogenous population.

Abstract
Backround Tongue squamous cell carcinoma (TSCC) is the most common malignant tumor in the oral cavity. An increasing number of studies have suggested that long noncoding RNA (lncRNA) plays an important role in the biological process of disease and is closely related to the occurrence and development of disease, including TSCC. Although many lncRNAs have been discovered, there remains a lack of research on the function and mechanism of lncRNAs. To better understand the clinical role and biological function of lncRNAs in TSCC, we conducted this study. Methods In this study, 162 tongue samples, including 147 TSCC samples and 15 normal control samples, were investigated and downloaded from The Cancer Genome Atlas (TCGA). We constructed a competitive endogenous RNA (ceRNA) regulatory network. Then, we investigated two lncRNAs as key lncRNAs using Kaplan-Meier curve analysis and constructed a key lncRNA-miRNA-mRNA subnetwork. Furthermore, gene set enrichment analysis (GSEA) was carried out on mRNAs in the subnetwork after multivariate survival analysis of the Cox proportional hazards regression model. Results The ceRNA regulatory network consists of six differentially expressed miRNAs (DEmiRNAs), 29 differentially expressed lncRNAs (DElncRNAs) and six differentially expressed mRNAs (DEmRNAs). Kaplan-Meier curve analysis of lncRNAs in the TSCC ceRNA regulatory network showed that only two lncRNAs, including LINC00261 and PART1, are correlated with the total survival time of TSCC patients. After we constructed the key lncRNA-miRNA -RNA sub network, the GSEA results showed that key lncRNA are mainly related to cytokines and the immune system. High expression levels of LINC00261 indicate a poor prognosis, while a high expression level of PART1 indicates a better prognosis.

Abstract
Oral cancer has a high annual incidence rate all over the world, and the tongue is the most frequently affected anatomic structure. The current standard care is ablative surgery of malignant neoplasm, followed by tongue reconstruction with free flap. However, such reconstructive modalities with postsurgery radiotherapy or chemotherapy can hardly support the functional recovery of the tongue-particularly, functional taste bud regeneration-in reconstructed areas, thus seriously affecting patients' prognosis and life quality. Using a critical-sized tongue defect model in rats, we show that combinatory transplantation of small intestinal submucosa-extracellular matrix (SIS-ECM) with gingival mesenchymal stem cells (GMSCs) or their derivative exosomes promoted tongue lingual papillae recovery and taste bud regeneration as evidenced by increased expression of CK14, CK8, and markers for type I, II, and III taste bud cells (NTPdase 2, PLC-β2, and AADC, respectively). In addition, our results indicate that GMSCs or their derivative exosomes could increase BDNF expression, a growth factor that plays an important role in the proliferation and differentiation of epithelial basal progenitor cells into taste bud cells. Meanwhile, we showed an elevated expression level of Shh-which is essential for development, homeostasis, and maintenance of the taste bud organ-in wounded areas of the tongue among animals treated with GMSC/SIS-ECM or exosome/SIS-ECM as compared with SIS-ECM control. Moreover, our data show that GMSCs or their derivative exosomes promoted innervation of regenerated taste buds, as evidenced by elevated expressions of neurofilament and P2X3 at the injury areas. Together, our findings indicate that GMSC/SIS-ECM and exosome/SIS-ECM constructs can facilitate taste bud regeneration and reinnervation with promising potential application in postsurgery tongue reconstruction of patients with tongue cancer.
