Comparing the Diagnostic Accuracy of Ultrasonography, CT, MRI, and PET/CT in Cervical Lymph Node Metastasis of Oral Squamous Cell Carcinoma. Biomedicines 2023; 11:3119. [PMID: 38137340 PMCID: PMC10740725 DOI: 10.3390/biomedicines11123119] [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: 10/06/2023] [Revised: 11/08/2023] [Accepted: 11/20/2023] [Indexed: 12/24/2023] Open
Abstract
(1) Background: In oral cancer staging, ultrasonography (US), computed tomography (CT), magnetic resonance imaging (MRI), and 2-deoxy-2-[fluorine-18]fluoro-D-glucose (FDG) with positron emission tomography/computed tomography (PET/CT) are routinely used in clinical practice. The present study is a retrospective examination of the diagnostic accuracy of cervical lymph node metastasis using US, CT, MRI, and PET/CT, with histopathological diagnosis as a reference, to compare the different diagnostic imaging modalities. (2) Methods: The participants included 16 patients with oral squamous cell carcinoma who underwent US-, CT-, MRI-, and PET/CT-based preoperative diagnostic imaging and simultaneous primary lesion resection and neck dissection, including 82 level regions and 424 lymph nodes. We compared the sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of each imaging modality based on the imaging results and the pathology results of metastasis. (3) Results: Of the four diagnostic imaging modalities, PET/CT exhibited the highest sensitivity but the lowest specificity and accuracy. US, CT, and MRI had high specificities. Comparing each level region and lymph node showed that differences were observed in PET/CT. (4) Conclusions: PET/CT to diagnose lymph node metastasis requires a comprehensive evaluation because it produces more false positives than other diagnostic imaging modalities. Using US, CT, and MRI, which have excellent spatial resolution, improves diagnostic accuracy at the lymph node level.

Identification of a serum-based microRNA signature that detects recurrent oral squamous cell carcinoma before it is clinically evident. Br J Cancer 2023; 129:1810-1817.

Abstract
BACKGROUND Survival rates for oral squamous cell carcinoma (OSCC) have remained poor for decades, a fact largely attributable to late-stage diagnoses and high recurrence rates. We report analysis of serum miRNA expression in samples from patients with high-risk oral lesions (HRL, including OSCC/carcinoma in situ lesions) and healthy non-cancer controls, with the aim of non-invasively detecting primary or recurrent disease before it is clinically evident. METHODS Discovery, test, and validation sets were defined from a total of 468 serum samples (305 HRL and 163 control samples). Samples were analysed using multiple qRT-PCR platforms. RESULTS A two-miRNA classifier comprised of miR-125b-5p and miR-342-3p was defined following discovery and test analyses. Analysis in an independent validation cohort reported sensitivity and specificity of ~74% for this classifier. Significantly, when this classifier was applied to serial serum samples taken from patients both before treatment and during post-treatment surveillance, it identified recurrence an average of 15 months prior to clinical presentation. CONCLUSIONS These results indicate this serum miRNA classifier is effective as a simple, non-invasive monitoring tool for earlier detection of recurrent disease when lesions are typically smaller and amenable to a wider array of treatment options to improve survival.

Clinical Experience with Autofluorescence Guided Oral Squamous Cell Carcinoma Surgery. Diagnostics (Basel) 2023; 13:3161. [PMID: 37891982 PMCID: PMC10605623 DOI: 10.3390/diagnostics13203161] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2023] [Revised: 10/02/2023] [Accepted: 10/05/2023] [Indexed: 10/29/2023] Open
Abstract
In our study, the effect of the use of autofluorescence (Visually Enhanced Lesion Scope-VELscope) on increasing the success rate of surgical treatment in oral squamous carcinoma (OSCC) was investigated. Our hypothesis was tested on a group of 122 patients suffering from OSCC, randomized into a study and a control group enrolled in our study after meeting the inclusion criteria. The preoperative checkup via VELscope, accompanied by the marking of the range of a loss of fluorescence in the study group, was performed before the surgery. We developed a unique mucosal tattoo marking technique for this purpose. The histopathological results after surgical treatment, i.e., the margin status, were then compared. In the study group, we achieved pathological free margin (pFM) in 55 patients, pathological close margin (pCM) in 6 cases, and we encountered no cases of pathological positive margin (pPM) in the mucosal layer. In comparison, the control group results revealed pPM in 7 cases, pCM in 14 cases, and pFM in 40 of all cases in the mucosal layer. This study demonstrated that preoperative autofluorescence assessment of the mucosal surroundings of OSCC increased the ability to achieve pFM resection 4.8 times in terms of lateral margins.

Abstract
Tumor recurrence in oral squamous cell carcinoma (OSCC) is frequent. However, no consensus about follow-up interval is available. The aim of this study was to analyze the recurrence pattern, detection method and associated parameters for possible risk stratification. Histopathological and epidemiological features were obtained retrospectively and correlated with tumor recurrence and overall survival, distant and lymph node metastases. A total of 760 patients were included, of which 216 patients showed tumor recurrence (mean after 24 ± 26 months). Within the first 12 months, 24% of the recurrences were detected. The primary detection method was clinical examination (n = 123, 57%). Tumor recurrence significantly correlated with advanced histopathological grading (G2/3 vs. G1, p < 0.000) and lymph node metastasis (p = 0.004). Tumor recurrence was frequent. Clinical examination was the primary detection method and manifestation within the first 6−12 months was high. The degree of histopathological grading may be useful for risk stratification.

Desmoglein-3 overexpression in oral squamous cell carcinoma is associated with metastasis formation and early recurrence: An immunohistochemical study. J Craniomaxillofac Surg 2021; 50:281-288.

Abstract
The purpose of this study was to determine the expression patterns of specific desmosomal cadherins (desmogleins [DSG] 1/2/3) in oral squamous cell carcinoma (OSCC), and to examine possible associations with clinicopathological parameters and recurrence rates. Changes in desmosomal cadherin assembly may promote tumor metastasis formation. Patients with surgically treated OSCC with 36-60 months of follow-up (median 46 months) qualified for inclusion in this retrospective cohort study. Demographic, clinical and pathohistological data were collected. DSG-1/2/3 expression patterns were determined by an immunohistochemical approach on tissue microarrays. Descriptive and inferential statistics and survival analyses were computed (p ≤ 0.05). The study sample consisted of 88 patients (female: 38; male: 50; average age: 63.02 ± 17.5 years). DSG-3 overexpression was detected in 45 of 88 specimens. The expression rates for DSG-1 (28/88) and DSG-2 (14/88) were low and inconspicuous. DSG-3 overexpression was significantly associated with poor histologic differentiation (G3, p = 0.001), the presence of cervical node metastasis at primary diagnosis (N+ status, p = 0.001) and early recurrence (p = 0.001). Due to its possible relevance for lymph node metastasis formation and early OSCC recurrence, determination of DSG-3 expression in OSCC specimens may be a valuable tool for treatment planning and post-therapeutic risk assessment.

Abstract
OBJECTIVE To identify the clinicopathological parameters that influence survival in patients with oral squamous cell carcinoma, in order to allow for the development of individualized surveillance programmes and reduce the delay in diagnosis of recurrence. MATERIALS AND METHODS Retrospective chart review of 553 patients with a treatment-naïve primary oral squamous cell carcinoma, who underwent primarily curative intended surgery. Exclusion criteria were neoadjuvant radio(chemo)therapy, follow-up < 1 year, perioperative death, inoperable disease, synchronous multiple malignancies and inadequate information on clinicopathological parameters. RESULTS The clinicopathological factors that influence overall survival, disease-free survival and locoregional control were calculated. In the multivariate survival analysis, the occurrence of recurrence, presence of extracapsular spread, T- and N-classification were shown to be independent risk factors for overall survival. CONCLUSION The identification of these risk factors can lead to the development of individualized follow-up programmes based on risk stratification. This allows for the earliest possible diagnosis of relapse which is essential to offer the patient a realistic second treatment chance and to improve survival rates.

Abstract
There is currently no consensus as to the ideal timing, frequency and modality of imaging for follow up of head and neck cancer patients. The aim of this study was to analyze the diagnostic accuracy of PET-CT versus MRI, and imaging at 3 versus 6 months for follow up of head and neck cancer patients treated with curative intent with no clinical signs of treatment failure. MATERIALS AND METHODS A retrospective study was performed for all head and neck cancers treated with curative intent at the Royal Derby Hospital. Data collected included demographic information, site of primary cancer, staging, treatment provided, type of follow up imaging performed and results of follow up imaging. Inclusion in the study was for oral, oropharyngeal and hypopharyngeal cancers treated with curative intent, asymptomatic patients, those who have had follow up imaging within 6 months of treatment, and those followed up for at least 2.5 years since treatment. RESULTS A total of 140 patients were included in the study. 25% of patients had evidence of recurrent/metastatic disease on imaging, 60% of which were identified within 6 months post treatment. The majority (60%) of failures were due to distant metastases. The sensitivity and specificity of both MRI and PET-CT was higher at 6 months post-treatment compared to 3 months post-treatment. Overall the sensitivity and specificity for PET-CT and MRI within 3-6 months post treatment were 94.7% and 83.5% and 60% and 85.7% respectively for identifying treatment failure. CONCLUSION Follow up Imaging at 6 months post treatment is more likely to accurately identify treatment failures with fewer false positives than imaging at 3 months. PET-CT is preferable to MRI for identifying post treatment locoregional and distant treatment failure.

Abstract
Aim: The aim of this study was to assess the effectiveness of the follow-up (FU) of patients after head and neck cancer treatment. Materials & methods: This is a retrospective cross-sectional study and concerns the analysis of outpatient records of 85 women and 355 men who reported at FU visits between 2011 and 2016 in ENT Department in the University Of Medical Sciences in Poznan, Poland. Results: The value of the FU scheme was confirmed by a high rate of recurrence detected in a medical examination (60%) and routine imaging studies (27%), as opposed to only 13% in spontaneous reports. Conclusion: The FU therapeutic profit in the form of high percentages of preclinical relapse at a reasonable cost is justified medically and socially.

Abstract
Background Metformin is a biguanide, belonging to the oral hypoglycemic agents and is a widely used in the treatment of type 2 diabetes. Evidence indicate that Metformin inhibits cell proliferation in several human cancers and inhibits the Warburg phenomenon in tumor cells. Results Low PDH levels were observed in OSCC, and Metformin promotes an increase in PDH levels in hypoxic conditions. Metformin also reduced HIF-1α mRNA and protein levels. Metformin demonstrated antiproliferative effects, inhibited migration, increased the number of apoptotic cells and increased the transcription of caspase 3. Objective The present study aims to explore the effects of Metformin in hypoxic conditions. Specifically, we focused on pyruvate dehydrogenase (PDH), (hypoxia-inducible factor 1α) HIF-1α levels and the oral squamous cell carcinoma (OSCC) cell phenotype. Additionally, we also investigated a theoretical consequence of Metformin treatment. Methods PDH levels in patients with OSCC and oral dysplasia were evaluated. Metformin was administered in vitro to test the effect of Metformin under hypoxic conditions. The results were complemented by Bioinformatics analyses. Conclusions In conclusion, our current findings show that Metformin reduces HIF-1α gene expression and increases PDH expression. Metformin inhibits cell proliferation and migration in the OSCC cell line model. Additionally, Metformin enhances the number of apoptotic cells and caspase 3 levels. Interestingly enough, Metformin did not increase the mutant p53 levels under hypoxic conditions.

Oral Oncol 2015; 53:80-4.

Abstract
OBJECTIVES Oral squamous cell carcinomas, and tongue malignancies in particular, are among the most common tumors of the oral cavity. Classification for therapeutic and prognostic purposes is routinely made using the tumor, node, metastasis (TNM) system; however, current definitions do not include tumor thickness. We therefore aimed to identify variables associated with survival, and to evaluate the correlation between tumor thickness and the occurrence of lymph node metastasis. PATIENTS AND METHODS All patients undergoing radical tumor resection for squamous cell carcinomas of the tongue between 2000 and 2012 were included. Specimens were analyzed histopathologically and co-variables were interpreted. Follow-up was performed clinically and radiologically for at least 3years according to current guidelines. RESULTS We included 492 patients who had a median follow-up of 70months. Variables associated with survival (p<0.05) were age, tumor stage, N stage, UICC (Union for International Cancer Control) stage, tumor grade, and recurrence. In the receiver operating characteristic curve and Youden-Index analyses, the optimal tumor thickness cut-off was 8mm to detect significant differences in overall survival. CONCLUSION We highlight the importance of tumor thickness as a predictive variable in tongue cancer. Specifically, a cut-off point of 8mm allowed for a more accurate and statistically precise prediction of lymph node metastasis. These findings could supplement the current classification of tongue cancers and form the basis for treatment.

Oral brush biopsy and melanoma-associated antigens A (MAGE-A) staining in clinically suspicious lesions. J Craniomaxillofac Surg 2015; 43:2214-8. [PMID: 26589180 DOI: 10.1016/j.jcms.2015.10.018] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2015] [Revised: 09/18/2015] [Accepted: 10/08/2015] [Indexed: 11/26/2022] Open
Abstract
PURPOSE In oral cancer and in other tumor entities, melanoma-associated antigens are present. These antigens contribute to tumor progression and poor prognosis, and reduce the cytotoxicity of antineoplastic drugs. The aim of this study was to investigate the diagnostic potential of these antigens in combination with oral brush biopsies. MATERIAL AND METHODS We analyzed 72 oral brush biopsy specimens for melanoma-associated antigens A (MAGE-A) expression by immunocytologic staining with the MAGE-A 57B antibody. A total of 24 healthy specimens, 15 lichen ruber cases, 18 leukoplakia cases, and 15 invasive carcinomas were studied. Incisional biopsy served as the gold standard. RESULTS In total, 66 of 72 specimens (91.6%) could be assessed. Twelve of 15 (80%) carcinomas stained positive for MAGE-A. MAGE-A staining was detected in four of 51 nonmalignant specimens, resulting in a false-positive rate of 7.8%. However, MAGE-A positive staining was significantly correlated with oral squamous cell carcinoma (p < 0.0005). Sensitivity and specificity for MAGE-A staining and carcinoma were 80% and 92.2%, respectively. The diagnostic accuracy was 89.4%. CONCLUSION Our results indicate that oral brush biopsy with MAGE-A staining serves as an additional tool for use in oral cancer diagnosis. These findings might help to facilitate an easier and more representative surveillance of the mucosa, particularly for large areas of altered mucosa.
