Giap HV, Jeon JY, Kim KD, Lee KJ. Conservative orthodontic treatment for severe pathologic migration following total glossectomy: A case report. Korean J Orthod 2022; 52:298-307. [PMID: 35418522 PMCID: PMC9314215 DOI: 10.4041/kjod21.215] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2021] [Revised: 01/09/2022] [Accepted: 01/14/2022] [Indexed: 11/10/2022] Open
Abstract
Glossectomy combined with radiotherapy causes different levels of tongue function disorders and leads to severe malocclusion, with poor periodontal status in cancer survivors. Although affected patients require regular access to orthodontic care, special considerations are crucial for treatment planning. This case report describes the satisfactory orthodontic management for the correction of severe dental crowding in a 43-year-old female 6 years after treatment for tongue cancer with total glossectomy combined with radiotherapy, to envision the possibility of orthodontic care for oral cancer survivors. Extraction was performed to correct dental crowding and establish proper occlusion following alignment, after considering the possibility of osteoradionecrosis. Orthodontic mini-implants were used to provide skeletal anchorage required for closure of the extraction space and intrusion of the anterior teeth. The dental crowding was corrected, and Class I occlusal relationship was established after 36 months of treatment. The treatment outcome was sustained after 15 months of retention, and long-term follow-up was recommended.

Abstract
Background: As the human papillomavirus (HPV) infections are detected in healthy oral mucosa as well as in oral lesions, dental practitioners have an important role in detecting any possible lesions that might be caused by this virus. Therefore, the aim of this study was to investigate the outcomes of orthodontic treatments and HPV infections and to report a rare case of ongoing orthodontic treatment superposed on an HPV infection. Methods: An electronic English literature research of the articles published between the years 2011–2021 was conducted between December 2021–February 2022, accessing PubMed, Web of Science, Embase, Scopus, and Google Scholar. The terms “HPV”, “orthodontics”, “orthodontic treatment”, “tooth movement”, “tooth mobility”, and “malocclusion” were searched. The following inclusion criteria were pursued: articles published in English language; studies reporting HPV infection in subjects with past or ongoing orthodontic treatment; and case reports of subjects with HPV and orthodontic treatment. Exclusion criteria were: articles in languages other than English, studies related to malignancies other than HPV and orthodontic treatment; and studies reporting patients with HPV and no orthodontic treatment. Results: Following the systematic review, which includes six papers, a case of orthodontic treatment superposed on a HPV infection is presented. Conclusion: Incumbent, postponed HPV infection on an ongoing orthodontic treatment might affect treatment outcome and patient compliance.

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

Abstract
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.

High SOX8 expression promotes tumor growth and predicts poor prognosis through GOLPH3 signaling in tongue squamous cell carcinoma. Cancer Med 2020; 9:4274-4289. [PMID: 32307911 PMCID: PMC7300415 DOI: 10.1002/cam4.3041] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2019] [Revised: 02/24/2020] [Accepted: 03/14/2020] [Indexed: 01/29/2023] Open
Abstract
According to our previous study, GOLPH3 is markedly up-expressed in tongue squamous cell carcinoma (TSCC), which is also associated with poor survival. However, it remains unclear about key upstream and downstream mechanisms of GOLPH3. This study aimed to illuminate new mechanisms modulating GOLPH3 upregulation and promoting TSCC development at the molecular level. Using mass spectrometry and agarose-streptavidin-biotin pull-down analyses, SOX8 (SRY-Box 8) was identified to be the new protein to bind the GOLPH3 promoter within TSCC cells, which was further verified to be the regulator of GOLPH3 upregulation. The knockdown of SOX8 suppressed the promoter activity of GOLPH3, while secondarily inhibiting TSCC cell proliferation both in vivo and in vitro. Interestingly, GOLPH3 overexpression rescued the SOX8 knockdown-mediated suppression on TSCC proliferation. Additionally, exogenous over-expression of SOX8 also activated the activity of promoter as well as GOLPH3 expression, in the meantime of promoting TSCC development. Moreover it was discovered that SOX8 regulated GOLPH3 expression through interacting with TFAP2A. Moreover our results suggested that the SOX8 level was increased within tumor tissue compared with that in para-cancer normal counterpart, which showed positive correlation with the GOLPH3 level. According to Kaplan-Meier analyses, TSCC cases having higher SOX8 and GOLPH3 expression were associated with poorer prognostic outcomes. Taken together, this study reveals that SOX8 enhances the TSCC cell growth via the direct transcriptional activation of GOLPH3, which also indicates the potential to use SOX8/GOLPH3 pathway as the treatment target among TSCC patients.

Abstract
Background The occurrence of oral tongue squamous cell carcinoma (TSCC) in nonsmoking young adults, especially females, has increased. Yet, there is no clear evidence to support the existence of any single determinant. This case reports the presence of TSCC in an 18-year-old female with no recognizable risk factor for oral cancer development. Methods Histological examination and p16 immunohistochemistry were performed. Formalin-fixed paraffin-embedded sections were prepared from resected tissue and DNA was extracted for molecular OncoScan analysis. Results Histological and immunochemical analysis showed a p16-negative poorly differentiated keratinizing squamous cell carcinoma. OncoScan analysis of this tumor revealed a high confidence TP53:p.R213*:c.637C>T somatic mutation as well as copy number alterations of chromosomal regions including gains of 1p, 3q, 5p, 7p, 8p, 8q, 11q, 15q, 17q, and 20p, and losses on 1p, 3p, 18q, and 22q. Conclusion The TP53:p.R213*:c.637C>T mutation detected is indicative of a genetic predisposition to cancer and it is the first to be reported in TSCC in a nonsmoking young adult. Level of Evidence Case report.

Abstract
OBJECTIVES Squamous cell carcinoma (SCC) is a malignant disease that affects the oral cavity. Lidocaine has shown antiproliferative and cytotoxic activity on several cell types. The rapid dispersion is a limitation issue; however, the complexation in cyclodextrin improved pharmacological features and modified the drug release. This study investigated the effects of lidocaine (lido) complexed with 2-hydroxypropyl-β-cyclodextrin (HP-β-CD-lido) on cell viability and proliferation of human tongue squamous cell carcinoma SCC9 and SCC25. METHODS The complex formation was confirmed by differential scanning calorimetry (DSC) and scanning electron microscopy (SEM). Cells SCC9 and SCC25 were exposed to lido and HP-β-CD-lido (40-4000 μm), and the effects on cell viability (MTT) and antiproliferative activity (SRB) were tested. KEY FINDINGS Differential scanning calorimetry and SEM results demonstrated the occurrence of host-guest interaction. Lido and HP-β-CD-lido (4000 μm) significantly reduced the viability of SCC9 cells to 83% and 63%, respectively. The viability of SCC25 treated with lido, and HP-β-CD-lido (4000 μm) was 71% and 44%, respectively. Lido (4000 μm) reduced the proliferation of SCC9 and SCC25 to 39.5% and 23.7%, respectively. HP-β-CD-lido (4000 μm) was cytotoxic for both cell lines. CONCLUSIONS HP-β-CD was able to potentiate the in vitro cytotoxic effects of lidocaine on human squamous cell carcinoma.

Abstract
Head and neck squamous cell carcinoma (HNSCC), accounting for more than 80% in head and neck malignancies, kills thousands of people a year in the world. Despite most of the patients are more than 45, and the occurrences of head and neck cancer shows a decreasing trend; however, horribly, the incidences of the patients under 45 years old is steadily increasing. Hence, it's of vital importance to get more pathogen information about risk factors of HNSCC in children and young adults. This review outlines the etiologic spectrum of HNSCC, especially oral/oropharyngeal squamous cell carcinoma, in patients under 45 years of age.

Abstract
BACKGROUND Orbital apex syndrome (OAS) is a complex and uncommon disorder that typically damages multiple cranial nerves in association with optic nerve dysfunction. OAS is associated with several different pathologies, however; only a few cases have been reported in association with head and neck cancer (HNC) so far. MATERIAL AND METHODS A case series of HNC patients diagnosed with OAS is described including clinicopathological data, image findings, and disease outcome. RESULTS Ptosis and diplopia were diagnosed in four male patients with mean age of 61.2 years who were undergoing treatment for late-stage carcinomas of the tongue, larynx, and nasopharynx, eventually leading to the diagnosis of OAS. The mean overall survival rate after the diagnosis of OAS was 9.5 months. CONCLUSIONS The current study reinforces evidence that OAS indicates poor prognosis and highlights the importance of early diagnosis.

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
OBJECTIVE To evaluate the distribution of oral and maxillofacial pathologies (OMFPs) and its association with patient age in young- and middle-aged adults. METHODS Distribution of histopathologically diagnosed OMFPs (n = 385) treated during 2007-2010 was recorded and the association with patient age was retrospectively analyzed. RESULTS The main diagnostic categories included benign exophytic lesions (45.3%), white benign lesions (13.5%), potentially malignant lesions/disorders (10.1%), intrabony lesions (9.8%), mucosal discoloration (7.8%), benign pigmented lesions (7.3%), chronic trauma/inflammation (3.9%), and oral malignancy (2.1%). Potentially malignant lesions/disorders as a diagnostic category were positively associated with age (OR = 1.07 for 1 year; P < 0.001) and specifically the diagnoses of oral lichen planus (OR = 1.04 for 1 year; P = 0.037) and dysplastic changes (OR = 1.08 for 1 year; P = 0.013) that comprised this category. Pigmented melanocytic lesions were negatively associated with age (OR = 0.94 for 1 year; P = 0.039) as well as benign/reactive exophytic lesions (OR = 0.98 for 1 year; P = 0.038), the latter included the histopathological diagnosis of benign salivary gland pathologies (OR = 0.90 for 1 year; P < 0.001). CONCLUSION This study provided baseline information regarding the distribution OMFPs among young- and middle-aged adults. It is important to highlight the high frequency of potentially malignant lesions/disorders and oral malignancy in young- and middle-aged adults, as these lesions require lifelong follow-up.
