The Role of Glucose Transporters in Oral Squamous Cell Carcinoma. Biomolecules 2021; 11:biom11081070. [PMID: 34439735 PMCID: PMC8392467 DOI: 10.3390/biom11081070] [Citation(s) in RCA: 27] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2021] [Revised: 07/18/2021] [Accepted: 07/20/2021] [Indexed: 02/06/2023] Open
Abstract
Oral squamous cell carcinoma (OSCC) is a prevalent malignancy associated with a poor prognosis. The Warburg effect can be observed in OSCCs, with tumours requiring a robust glucose supply. Glucose transporters (GLUTs) and sodium-glucose co-transporters (SGLTs) are overexpressed in multiple malignancies, and are correlated with treatment resistance, clinical factors, and poor overall survival (OS). We conducted a systematic review to evaluate the differences in GLUT/SGLT expression between OSCC and normal oral keratinocytes (NOK), as well as their role in the pathophysiology and prognosis of OSCC. A total of 85 studies were included after screening 781 papers. GLUT-1 is regularly expressed in OSCC and was found to be overexpressed in comparison to NOK, with high expression correlated to tumour stage, treatment resistance, and poor prognosis. No clear association was found between GLUT-1 and tumour grade, metastasis, and fluorodeoxyglucose (FDG) uptake. GLUT-3 was less thoroughly studied but could be detected in most samples and is generally overexpressed compared to NOK. GLUT-3 negatively correlated with overall survival (OS), but there was insufficient data for correlations with other clinical factors. Expression of GLUT-2/GLUT-4/GLUT-8/GLUT-13/SGLT-1/SGLT-2 was only evaluated in a small number of studies with no significant differences detected. GLUTs 7 and 14 have never been evaluated in OSCC. In conclusion, the data demonstrates that GLUT-1 and GLUT-3 have a role in the pathophysiology of OSCC and represent valuable biomarkers to aid OSCC diagnosis and prognostication. Other GLUTs are comparatively understudied and should be further analysed because they may hold promise to improve patient care.

Prediction of the treatment outcome using machine learning with FDG-PET image-based multiparametric approach in patients with oral cavity squamous cell carcinoma. Clin Radiol 2021; 76:711.e1-711.e7. [PMID: 33934877 DOI: 10.1016/j.crad.2021.03.017] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2020] [Accepted: 03/26/2021] [Indexed: 12/15/2022]
Abstract
AIM To investigate the value of machine learning-based multiparametric analysis using 2-[18F]-fluoro-2-deoxy-d-glucose positron-emission tomography (FDG-PET) images to predict treatment outcome in patients with oral cavity squamous cell carcinoma (OCSCC). MATERIALS AND METHODS Ninety-nine patients with OCSCC who received pretreatment integrated FDG-PET/computed tomography (CT) were included. They were divided into the training (66 patients) and validation (33 patients) cohorts. The diagnosis of local control or local failure was obtained from patient's medical records. Conventional FDG-PET parameters, including the maximum and mean standardised uptake values (SUVmax and SUVmean), metabolic tumour volume (MTV), and total lesion glycolysis (TLG), quantitative tumour morphological parameters, intratumoural histogram, and texture parameters, as well as T-stage and clinical stage, were evaluated by a machine learning analysis. The diagnostic ability of T-stage, clinical stage, and conventional FDG-PET parameters (SUVmax, SUVmean, MTV, and TLG) was also assessed separately. RESULTS In support-vector machine analysis of the training dataset, the final selected parameters were T-stage, SUVmax, TLG, morphological irregularity, entropy, and run-length non-uniformity. In the validation dataset, the diagnostic performance of the created algorithm was as follows: sensitivity 0.82, specificity 0.7, positive predictive value 0.86, negative predictive value 0.64, and accuracy 0.79. In a univariate analysis using conventional FDG-PET parameters, T-stage and clinical stage, diagnostic accuracy of each variable was revealed as follows: 0.61 in T-stage, 0.61 in clinical stage, 0.64 in SUVmax, 0.61 in SUVmean, 0.64 in MTV, and 0.7 in TLG. CONCLUSION A machine-learning-based approach to analysing FDG-PET images by multiparametric analysis might help predict local control or failure in patients with OCSCC.

Abstract
Molecular changes that affect mitochondrial glycolysis have been associated with the maintenance of tumor cells. Some metabolic factors have already been described as predictors of disease severity and outcomes. This systematic review was conducted to answer the question: Is the glycolytic pathway correlated with the prognosis of oral squamous cell carcinoma (OSCC)? A search strategy was developed to retrieve studies in English from PubMed, Scopus, and ISI Web of Science using keywords related to squamous cell carcinoma, survival, and glycolytic pathway, with no restriction of publication date. The search retrieved 1273 publications. After the titles and abstracts were analyzed, 27 studies met inclusion criteria. Studies were divided into groups according to two subtopics, glycolytic pathways and diagnosis, which describe the glycolytic profile of OSCC tumors. Several components of tumor energy metabolism found in this review are important predictors of survival of patients with OSCC.

Abstract
OBJECTIVE To assess the utility of deep learning analysis using 18F-fluorodeoxyglucose (FDG) uptake by positron emission tomography (PET/CT) to predict disease-free survival (DFS) in patients with oral cavity squamous cell carcinoma (OCSCC). METHODS One hundred thirteen patients with OCSCC who received pretreatment FDG-PET/CT were included. They were divided into training (83 patients) and test (30 patients) sets. The diagnosis of treatment control/failure and the DFS rate were obtained from patients' medical records. In deep learning analyses, three planes of axial, coronal, and sagittal FDG-PET images were assessed by ResNet-101 architecture. In the training set, image analysis was performed for the diagnostic model creation. The test data set was subsequently analyzed for confirmation of diagnostic accuracy. T-stage, clinical stage, and conventional FDG-PET parameters (the maximum and mean standardized uptake value (SUVmax and SUVmean), heterogeneity index, metabolic tumor volume (MTV), and total lesion glycolysis (TLG) were also assessed with determining the optimal cutoff from training dataset and then validated their diagnostic ability from test dataset. RESULTS In dividing into patients with treatment control and failure, the highest diagnostic accuracy of 0.8 was obtained using deep learning classification, with a sensitivity of 0.8, specificity of 0.8, positive predictive value of 0.89, and negative predictive value of 0.67. In the Kaplan-Meier analysis, the DFS rate was significantly different only with the analysis of deep learning-based classification (p < .01). CONCLUSIONS Deep learning-based diagnosis with FDG-PET images may predict treatment outcome in patients with OCSCC. KEY POINTS • Deep learning-based diagnosis of FDG-PET images showed the highest diagnostic accuracy to predict the treatment outcome in patients with oral cavity squamous cell carcinoma. • Deep learning-based diagnosis was shown to differentiate patients between good and poor disease-free survival more clearly than conventional T-stage, clinical stage, and conventional FDG-PET-based parameters.

Abstract
Alterations in histone modifications play a crucial role in the progression of various types of cancer. The histone methyltransferase SETDB1 catalyzes the addition of methyl groups to histone H3 at lysine 9. Here, we describe how overexpression of SETDB1 contributes to melanoma tumorigenesis. SETDB1 is highly amplified in melanoma cells and in the patient tumors. Increased expression of SETDB1, which correlates with SETDB1 amplification, is associated with a more aggressive phenotype in in vitro and in vivo studies. Mechanistically, SETDB1 implements its effects via regulation of thrombospondin 1, and the SET-domain of SETDB1 is essential for the maintenance of its tumorigenic activity. Inhibition of SETDB1 reduces cell growth in melanomas resistant to targeted treatments. Our results indicate that SETDB1 is a major driver of melanoma development and may serve as a potential future target for the treatment of this disease.

Abstract
Positron emission tomography/computed tomography (PET/CT) examinations are indispensable in determining the stage, evaluating the treatment response, and diagnosing recurrence and metastasis during oral cancer treatment. In this study, we examined the correlation between the maximum standardized uptake value (SUVmax) for 18F-FDG PET/CT and the progressive factors, biological characteristics, and prognosis of oral cancer. We included 52 cases of oral squamous cell carcinoma with surgery as the initial treatment. Inclusion criteria included tumor diameter of ≥ 1 cm excluding superficial cancer. We performed 18F-FDG PET/CT examinations before surgery and determined the correlation between SUVmax and clinicopathological factors, such as histological grade, Ki-67 expression, as well as progress factors. SUVmax was significantly correlated with clinical T stage, vascular invasion, lymphatic invasion, Ki-67 expression, and postoperative event (recurrence or metastasis) in Student's t test. Using a cut-off SUVmax of 8.0, clinical T stage, lymph node metastasis, vascular invasion, infiltrative pattern, and Ki-67 expression significantly correlated in chi-squared test. Although observed and expected 3-year overall survival rates were not significantly different, observed and expected 3-year disease-free survival rates were significantly different. Analyzing each clinicopathological factor using various data obtained from 18F-FDG PET/CT scans may be useful to determine prognosis during oral cancer treatment.

Abstract
The present study examined whether the pathological tumor volume (PTV) was correlated with the survival outcomes in patients with oral squamous cell carcinoma (SCC) and clinical lymph node metastasis. Forty-seven patients who underwent radical surgery without preoperative treatment were enrolled. The PTV of the primary tumor, which was surgically resected without preoperative treatment, was calculated based on the diameters in three dimensions. A survival analysis was performed using a Cox proportional hazards model. A PTV of ≥18 cm3 was significantly correlated with shorter overall survival (P<0.01) and local recurrence-free survival (P<0.01) in a univariate analysis. A multivariate analysis with adjustment for the pathological stage (stage I–II/III–IV), primary site (tongue/others) and positive surgical margin and/or extracapsular extension (absent/present) showed that a PTV of ≥18 cm3 was significantly correlated with shorter overall survival (P<0.01) and local recurrence-free survival (P<0.01). The present findings suggested that PTV in oral SCC provides a prognostic parameter that may predict shorter or longer overall and local recurrence-free survival.

Abstract
A novel system auxiliary to the Union for International Cancer Control classification may allow the prognosis of patients with malignant tumors at similar stages to be predicted, as currently this is challenging. The present study generated a novel system to predict populations at low risk among patients with stage III/IV oral squamous cell carcinoma (OSCC). A total of 41 patients who were diagnosed at stages III/IV OSCC and underwent surgical tumor resection were analyzed. Band-like or follicular lymphocyte infiltration, intraepithelial micro-abscess formation and natural killer (NK) cell infiltration were histopathologically evaluated. Cox's proportional hazards regression model was used to identify prognostic factors, and a set of factors was selected from a combination of those prognostic factors to create a logic covariate model. A logic regression analysis for 41 patients with OSCC revealed that the presence of intraepithelial micro-abscesses and a lower density of NK cells were significantly associated with a favorable prognosis among patients with stage III/IV OSCC. These results suggested that the host innate immune responses, including neutrophil and NK cell infiltrations, are useful for prognostic prediction in patients with advanced malignant tumors.

Abstract
Treatment of thyroid cancer has incurred much focus because of its high prevalency. As a new strategy treating thyroid cancer, hyperthermia takes several advantages compared with surgery or chemotherapy, including minimal invasion, low systematic toxicity and the ability to enhance the immunogenicity of cancer cells with the expression Hsp70 which serves as Toll-like receptors-4 (TLR-4 agonist). However, Hsp70 as a molecular chaperone can protect cells from heat induced apoptosis and therefore compromise the tumor killing effect of hyperthermia. In this study, to solve this problem, a combined hyperthermia therapy was employed to treat thyroid cancer. We prepared a probe with the tumor targeting agent AG to monitor thyroid tumor issue and generate heat to kill tumor cells in vivo. At the same time Quercetin (inhibitor of HSP70) and lipopolysaccharide (LPS) (agonist of TLR-4) were used for the combined hyperthermia therapy. The results showed that compared with free IR820, AG modification facilitated much enhanced cellular uptake and greatly pronounced tumor targeting ability. The combined therapy exhibited the most remarkable tumor inhibition compared with the single treatments both in vitro and in vivo. These findings verified that the new therapeutic combination could significantly improve the effect of hyperthermia and shed light on a novel clinical strategy in thyroid cancer treatment.

Abstract
The present study investigated the possible correlation between 18F-2-fluorodeoxyglucose (18F-FDG)-uptake parameters and clinicopathological parameters in hypopharyngeal squamous cell carcinoma (HPSCC). A total of 53 patients, newly diagnosed with HPSCC, received pretreatment 18F-FDG-positron emission tomography/computed tomography (PET/CT). Metabolic tumor volume (MTV), total lesion glycolysis (TLG), and maximum and peak standardized uptake values (SUVmax and SUVpeak) were calculated as 18F-FDG-uptake parameters of the primary tumor. Tumor thickness, depth of invasion and pathological tumor volume were pathologically measured. Upon univariate survival analysis, SUVmax ≥28.5, SUVpeak ≥19, MTV ≥12 and TLG ≥42 were significantly associated with a shorter overall survival (OS) time, and MTV ≥12 and TLG ≥42 were significantly associated with a shorter distant metastasis-free survival (DMFS) time. Upon multivariate analysis with adjustment for clinical T category and treatment group, patients with SUVmax ≥28.5 exhibited a significantly shorter OS time, while TLG ≥42 was significantly correlated with shorter OS and DMFS times. Upon simple regression analysis, TLG was found to be significantly associated with tumor thickness and depth of invasion, while MTV was found to be closely associated with pathological tumor volume. In conclusion, pretreatment 18F-FDG-PET/CT is likely to provide valuable prognostic parameters in HPSCC.

Abstract
We previously demonstrated that activated microglia release excessive glutamate through gap junction hemichannels and identified a novel gap junction hemichannel blocker, INI-0602, that was proven to penetrate the blood-brain barrier and be an effective treatment in mouse models of amyotrophic lateral sclerosis and Alzheimer disease. Spinal cord injury causes tissue damage in two successive waves. The initial injury is mechanical and directly causes primary tissue damage, which induces subsequent ischemia, inflammation, and neurotoxic factor release resulting in the secondary tissue damage. These lead to activation of glial cells. Activated glial cells such as microglia and astrocytes are common pathological observations in the damaged lesion. Activated microglia release glutamate, the major neurotoxic factor released into the extracellular space after neural injury, which causes neuronal death at high concentration. In the present study, we demonstrate that reduction of glutamate-mediated exitotoxicity via intraperitoneal administration of INI-0602 in the microenvironment of the injured spinal cord elicited neurobehavioral recovery and extensive suppression of glial scar formation by reducing secondary tissue damage. Further, this intervention stimulated anti-inflammatory cytokines, and subsequently elevated brain-derived neurotrophic factor. Thus, preventing microglial activation by a gap junction hemichannel blocker, INI-0602, may be a promising therapeutic strategy in spinal cord injury.

Abstract
BACKGROUND Although positron emission tomography computed tomography has proven diagnostic and staging value in head and neck carcinoma, it does not have optimal sensitivity or specificity. The positron emission tomography computed tomography fluorodeoxyglucose standardised uptake value has been shown to be associated with carcinoma stage. This study evaluated the impact of major clinicopathological factors on the standardised uptake value at the primary site and at neck lymph node metastases. SUBJECTS AND METHODS Two hundred and forty-three oral cavity and laryngopharyngeal carcinoma patients who underwent positron emission tomography computed tomography were included. Correlation between the positron emission tomography computed tomography standardised uptake value and various clinicopathological factors was analysed. RESULTS A positive correlation was found between the standardised uptake value and the size and depth of tumour infiltration, and lymph node positivity. Higher standardised uptake values were seen for more advanced tumour stages. The presence of perineural invasion, lymphatic invasion and extracapsular spread were all associated with increased standardised uptake values. CONCLUSION Most of the clinicopathological features of head and neck carcinoma which are well known to be poor prognostic factors have a significant impact on positron emission tomography computed tomography fluorodeoxyglucose standardised uptake value.

Abstract
CONCLUSION Maximum standardized uptake values (SUVmax) have prognostic value for induction chemotherapy (ICT) response and survival in oropharyngeal and hypopharyngeal squamous cell carcinoma (OHSCC) patients. Pretreatment positron emission tomography with the use of fluorodeoxyglucose ((18)F-FDG PET) may be an aid in deciding the treatment strategy in OHSCC patients. OBJECTIVES We investigated the association between pretreatment (18)F-FDG PET and response to ICT and survival in OHSCC patients. METHODS We conducted a retrospective cohort study of 58 OHSCC patients treated at Aichi Cancer Center Hospital. The predictive impact of SUVmax of the primary tumor site was evaluated using statistical multivariate proportional hazard models. RESULTS Thirty-one cases (53%) were located in the oropharynx and 27 (47%) in the hypopharynx. Median SUVmax was 11.6 (range 3.2-23.5), and was significantly higher in the 8 patients with less than stable disease than in the 50 with more than partial response (median SUVmax, 17.3 vs 11.1; p = 0.002). In multivariate analysis, hazard ratios for the medium and high SUVmax groups relative to the low group were 3.07 (95% confidence interval, 0.62-15.29; p = 0.170) and 4.71 (0.97-22.89; p = 0.055), respectively, and the dose-response relationship was statistically significant (p trend = 0.047). A similar tendency was observed on subclassification by oropharynx and hypopharynx.

Abstract
Adriamycin (ADM) has been effective against many types of solid tumors in clinical applications. However, its use is limited because of systemic toxicities, primarily cardiotoxicity, and multidrug resistance. In this study, a new active receptor-mediated complex, ADM conjugated with 2-amino-2-deoxy-d-glucose and succinic acid (2DG-SUC-ADM), was designed to target tumor cells through glucose transporter 1 (GLUT1). MTT assay and confocal images showed that the complex had better inhibition rate to tumor cells and low toxicity to normal cells. Most importantly, the complex displayed a potential to reverse overcome multidrug resistance in cancer cells, with more complex transported into the nucleus of tumor cells. Our in vivo experiments also showed that this new complex could significantly decrease organ toxicity and enhance the antitumor efficacy compared with free ADM, indicating a promising drug of 2DG-SUC-ADM for targeted cancer therapy.

Abstract
OBJECTIVES We investigated the relationship between overall survival of patients and pretreatment [(18)F]-2-fluorodeoxyglucose ((18)F-FDG) uptake, assessed by positron emission tomography combined with computed tomography (PET/CT) in hypopharyngeal squamous cell carcinoma. METHODS Thirty-one patients who were newly diagnosed as resectable hypopharyngeal squamous cell carcinoma underwent pretreatment (18)F-FDG-PET/CT. We used the maximum standardized uptake value (SUVmax) as (18)F-FDG uptake. Overall survival rate was calculated by the Kaplan-Meier method. RESULTS The median SUVmax was 11.53 (range 2.49-22.33). Patients with SUVmax ≥ 13 significantly exhibited shorter overall survival in univariate analysis (p < 0.01). Moreover, by Cox proportional hazards model of multivariate analysis, SUVmax ≥ 13 was a significant prognostic factor independent of clinical T and N classification, and treatment group (p < 0.02). CONCLUSIONS These results suggested that SUVmax obtained by pretreatment (18)F-FDG PET/CT assessment is an important prognostic factor in patients with hypopharyngeal squamous cell carcinoma.

Abstract
Purpose To evaluate the prognostic value of preoperative neck lymph node (LN) assessment with 18F-fluorodeoxyglucose positron emission tomography (18F-FDG PET), computed tomography (CT), and magnetic resonance imaging (MRI) in oral cavity squamous cell carcinoma (OSCC) patients with pathologically positive LN. Materials and Methods In total, 47 OSCC patients with pathologically positive LN were retrospectively reviewed with preoperative 18F-FDG PET and CT/MRI. All patients underwent surgical resection, neck dissection and postoperative adjuvant radiotherapy and/or chemotherapy between March 2002 and October 2010. Histologic correlation was performed for findings of 18F-FDG PET and CT/MRI. Results Thirty-six (76.6%) of 47 cases were correctly diagnosed with neck LN metastasis by 18F-FDG PET and 32 (68.1%) of 47 cases were correctly diagnosed by CT/MRI. Follow-up ranged from 20 to 114 months (median, 56 months). Clinically negative nodal status evaluated by 18F-FDG PET or CT/MRI revealed a trend toward better clinical outcomes in terms of overall survival, disease-free survival, local recurrence-free survival, regional nodal recurrence-free survival, and distant metastasis-free survival rates even though the trends were not statistically significant. However, there was no impact of neck node standardized uptake value (SUVmax) on clinical outcomes. Notably, SUVmax showed significant correlation with tumor size in LN (p < 0.01, R2 = 0.62). PET and CT/MRI status of LN also had significant correlation with the size of intranodal tumor deposit (p < 0.05, R2 = 0.37 and p < 0.01, R2 = 0.48, respectively). Conclusion 18F-FDG PET and CT/MRI at the neck LNs might improve risk stratification in OSCC patients with pathologically positive neck LN in this study, even without significant prognostic value of SUVmax.

Abstract
Glucose plays a central role in the cellular energy metabolism. Malignant tumors exhibit an elevated rate of glycolysis over normal tissues. In this study, two near-infrared fluorescent dyes, Cypate and ICG-Der-02, with different water solubility, were conjugated to 2-amino-2-deoxy-D-glucose (2DG) to form Cypate-2DG and ICG-Der-02-2DG, respectively, for NIR fluorescent imaging of tumors in nude mice. The clear routes and tumor targeting abilities of the two NIR fluorescent 2DG probes were compared. Results showed that ICG-Der-02-2DG with higher hydrophilicity was cleared faster by kidneys than the more lipophilic Cypate-2DG. Cypate-2DG had slower but stronger tumor targeting ability compared with ICG-Der-02-2DG. To investigate the correlation between the targeting ability of the probe and the glucose transporter (GLUT1) expression levels of cancer cells, the accumulation of Cypate-2DG in tumors was assessed in MCF-7/estradiol, U87MG, MCF-7 and MDA-MB-435 tumor xenografts, which express different levels of GLUT1. The results show that both Cypate-2DG and ICG-Der-02-2DG possess tumor targeting ability on all the tumors examined, with a proportional correlation to GLUT1 expression. The findings demonstrate the broad applicability of these molecular probes for optical imaging of tumors and glucose-related pathologies.
