[PMID: 38297336 PMCID: PMC10832330 DOI: 10.1186/s12903-024-03914-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2023] [Accepted: 01/18/2024] [Indexed: 02/02/2024] Open
Abstract
INTRODUCTION A prospective observational study was modified to assess the efficacy of surgery alone for the treatment of locally advanced oral squamous cell carcinoma. (LA-OSCC) MATERIALS AND METHODS This prospective, single-institution, single-arm study involved 174 patients who underwent major surgery for LA-OSCC. Participating patients did not receive postoperative radiation. After initial curative treatment, patients were routinely monitored via clinical examination and imaging. The follow-up period was 3-70 months. Tumour recurrence and death were considered as the Clinical End Point in Research. RESULTS The 5-year overall survival (OS), disease-free survival (DFS), and locoregional control rates for 174 patients were 66.7% (95% confidence interval [CI], 59.8 to 73.6), 66.1% (95% CI, 59.2 to 73.0), and 82.4% (95% CI, 76.5 to 88.3), respectively. CONCLUSION A study of patients with LA-OSCC treated with surgery alone may have the optimal therapeutic impact for LA-OSCC, as evidenced by solid data for our next RCT trial. This conclusion still needs to be validated in higher-level RCTs.

[PMID: 35949109 PMCID: PMC9769451 DOI: 10.1080/15384101.2022.2109897] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2022] [Revised: 04/08/2022] [Accepted: 08/02/2022] [Indexed: 12/24/2022] Open
Abstract
The aim is to explore the underlying mechanism of basic leucine zipper ATF-like transcription factor 2 (BATF2) in tongue squamous cell carcinoma (TSCC). The expression of BATF2 in TSCC tissues and corresponding adjacent normal TSCC tissues, human TSCC cell lines (SCC-15 and CAL-27) and human normal tongue epithelial cells NTEC was detected. Then, SCC-15 cells with stable BATF2 knockdown and CAL-27 cells with BATF2 overexpression were established to investigate the functional effect of BATF2 on TSCC. Thereafter, the effect of BATF2 on TSCC angiogenesis and BATF2 m6A methylation was also examined. BATF2 was significantly downregulated in TSCC tissues and cell lines, and BATF2 overexpression could suppress growth, metastasis and angiogenesis of TSCC. Mechanistically, vascular endothelial growth factor A (VEGFA) was identified as a downstream gene of BATF2, and it was confirmed that BATF2 suppressed growth, metastasis and angiogenesis of TSCC via inhibiting VEGFA. In addition, the N6-methyladenosine (m6A) modification of BATF2 mRNA mediated by METTL14 suppressed its expression in TSCC. METTL14/BATF2 axis could serve as a novel promising therapeutic candidate against angiogenesis for TSCC.

Abstract
Tongue squamous cell carcinoma (TSCC) is considered the most common malignant tumor among the oral squamous cell carcinomas with a poor prognosis. Understanding the underlying molecular mechanisms that underpin TSCC and its treatments is the focus of the research. Deregulated expression of microRNAs (miRNAs) has recently been implicated in various biological processes linked to cancer. Therefore, in this study, we attempted to investigate miRNAs and their targets expressed in TSCC, which could be involved in its oncogenesis. We performed next-generation sequencing of small RNAs and transcriptomes in H357 TSCC cell line and human oral keratinocytes as a control to find miRNAs and mRNAs that are differentially expressed (DE), which were then supplemented with additional expression datasets from databases, yielding 269 DE miRNAs and 2094 DE genes. The target prediction followed by pathway and disease function analysis revealed that the DE targets were significantly associated with the key processes and pathways, such as apoptosis, epithelial-mesenchymal transition, endocytosis and vascular endothelial growth factor signaling pathways. Furthermore, the top 12 DE targets were chosen based on their involvement in more than one cancer-related pathway, of which 6 genes are targeted by miR-128-3p. Real-time quantitative PCR validation of this miRNA and its targets in H357 and SCC9 TSCC cells confirmed their possible targeting from their reciprocal expression, with MAP2K7 being a critical target that might be involved in oncogenesis and progression of TSCC by acting as a tumor suppressor. Further research is underway to understand how miR-128-3p regulates oncogenesis in TSCC via MAP2K7 and associated pathways.

Abstract
Background Some head and neck cancer surgeons found that many patients with locally advanced head and neck squamous cell carcinoma (LA-HNSCC) without postoperative radiotherapy (PORT) also have a good prognosis. The purpose of this study was to determine the effect of PORT on survival in patients with LA-HNSCC. Methods A case-match cohort analysis was performed at two institutions on patients with LA-HNSCC. Patients who received surgery alone were case-matched 1: 1 with patients treated by surgery plus PORT based on pT, pN, tumor subsite etc. Results 114 patients were matched into 57 pairs, with a median follow-up period of 40.2 months. No difference in overall survival (OS, HR 0.88; 95% CI 0.50–1.58; P = 0.79) or disease-specific survival (DFS, 0.86; 95% CI 0.50–1.50; P = 0.76) was observed with no PORT. Conclusions PORT isn’t necessary for patients with LA-HNSCC who are treated for the first time as long as the head and neck cancer surgeon adhere to appropriate surgical concepts. The indications of PORT for patients with LA-HNSCC need to be further discussed.

Abstract
The aim of this study was to better understand posterior oral cavity cancer (POCC) and its surgical treatment. This was a retrospective study of 76 patients who were diagnosed with POCC and underwent surgical treatment. Twenty-eight patients were treated with anatomical unit resection surgery (AURS) and 48 patients with conventional surgery. After initial treatment with curative intent, the patients were followed-up regularly with clinical examinations and imaging; the median duration of follow-up was 30.9 months (range 2-67 months). The 3-year overall survival was 64.3% in the experimental AURS group and 39.6% in the conventional surgery control group (hazard ratio 0.49, 95% confidence interval 0.26-0.93; P=0.031). The 3-year disease-free survival was 64.3% in the experimental group and 37.5% in the control group (hazard ratio 0.53, 95% confidence interval 0.27-1.02; P=0.114). In conclusion, AURS is an effective surgical treatment for POCC that can considerably improve patient survival rates.

Abstract
Purpose The expression profile, clinical effects, and detailed roles of NOP14 antisense RNA 1 (NOP14-AS1) in tongue squamous cell carcinoma (TSCC) remain ambiguous and need to be further explored. Thus, this work was initiated to offer further solid evidence regarding the expression and roles of NOP14-AS1 in TSCC. Furthermore, additional efforts were exerted to reveal the molecular events by which NOP14-AS1 affects the malignant behaviours of TSCC. Methods NOP14-AS1 expression was detected in TSCC tissues and cell lines using quantitative reverse transcription-polymerase chain reaction. Cell Counting Kit-8 assay, flow cytometric analysis, Transwell migration and invasion assays, and xenograft tumor model analysis were performed to assess the malignant biological behaviors of TSCC cells after NOP14-AS1 depletion. Mechanistic studies were performed using bioinformatics analysis, luciferase reporter assay, RNA immunoprecipitation, and rescue experiments. Results NOP14-AS1 upregulation was identified in TSCC tissues and cell lines. Patients with TSCC exhibiting a high NOP14-AS1 expression faced shorter overall survival than those with a low NOP14-AS1 expression. Functionally, NOP14-AS1 depletion facilitated apoptosis and impeded cell proliferation, migration, and invasion in TSCC. In vivo, the growth of TSCC cells was hindered by NOP14-AS1 depletion. Mechanically, NOP14-AS1 functioned as a competing endogenous RNA by sponging microRNA-665 (miR-665), thereby overexpressing the target high mobility group box 3 (HMGB3) of miR-665. Lastly, rescue experiments confirmed that the introduction of HMGB3 overexpression plasmid or miR-665 inhibitor could abrogate the inhibition of aggressive phenotypes triggered by NOP14-AS1 knockdown. Conclusion NOP14-AS1 executed pro-oncogenic activities in TSCC cells by targeting the miR-665/HMGB3 axis. The NOP14-AS1/miR-665/HMGB pathway may be a valuable prognostic indicator and therapeutic target for preventing TSCC.

Abstract
Background Circular RNA_0001742 (circ_0001742) has been reported to be upregulated in tongue squamous cell carcinoma (TSCC) tissues/cells and regulate TSCC cell proliferation, migration, and invasion. This study aimed to further investigate the clinical significance of circ_0001742 in TSCC management. Methods Totally, 146 TSCC patients underwent surgical treatment were reviewed. Their fresh‐frozen tumor tissue and adjacent tissue were acquired for detecting circ_0001742 expression via reverse transcription‐quantitative polymerase chain reaction. According to circ_0001742 expression in tumor tissue, all patients were classified as tumor circ_0001742 low (0%‐50% percentile) and high (50%‐100% percentile) patients, the latter were further divided into the tumor circ_0001742 high+ (50%‐75% percentile), high++ (75%‐90% percentile), and high+++ (90%‐100% percentile) patients, respectively. Results Circ_0001742 expression was increased in TSCC tumor tissue compared with adjacent tissue, and it presented good value in discriminating tumor tissue from adjacent tissue (area under the curve (AUC): 0.870, 95% CI: 0.831‐0.910). Tumor high circ_0001742 expression was associated with higher T stage, N stage, and TNM stage, but not age, gender, or pathological grade. Furthermore, OS was reduced in tumor circ_0001742 high patients compared with tumor circ_0001742 low patients; moreover, OS was the shortest in tumor circ_0001742 high+++ patients, followed by tumor circ_0001742 high++ patients and tumor circ_0001742 high+ patients, and the longest in tumor circ_0001742 low patients. In addition, multivariate Cox's regression analysis revealed that higher tumor circ_0001742 expression was an independent predictive factor for decreased OS. Conclusion Circ_0001742 serves as a potential biomarker for advanced tumor stage and poor survival in TSCC patients.

Prognostic value of epithelial-mesenchymal transition-inducing transcription factors in head and neck squamous cell carcinoma: A meta-analysis. Head Neck 2020; 42:1067-1076. [PMID: 32048783 DOI: 10.1002/hed.26104] [Citation(s) in RCA: 26] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2019] [Revised: 01/14/2020] [Accepted: 01/28/2020] [Indexed: 12/26/2022] Open
Abstract
Epithelial-mesenchymal transition (EMT) plays a critical role in cancer progression and is primarily regulated by several EMT-inducing transcription factors (EMT-TFs), including TWIST1, TWIST2, SNAI1, SNAI2, ZEB1, and ZEB2. However, the prognostic value of EMT-TFs remains controversial in head and neck squamous cell carcinoma (HNSCC). Studies on the prognostic role of EMT-TFs in HNSCC were searched for in the Web of Science, Science Direct, Proquest, EMBASE, PubMed, and Cochrane Library. Meta-analysis was performed by using Revman 5.2 software. The pooled analysis showed that overexpression of EMT-TFs indicated a poor overall survival (OS) (HR = 1.93, 95% CI = 1.67-2.23) of HNSCC. Subgroup analysis for individual EMT-TFs revealed that overexpression of TWIST1 (HR = 1.61, 95% CI = 1.29-2.02), SNAI1 (HR = 2.17, 95% CI = 1.63-2.88), SNAI2 (HR = 1.90, 95% CI = 1.38-2.62), and ZEB1 (HR = 2.70, 95% CI = 1.61-4.53) were significantly associated with poor OS of HNSCC. These findings support the hypothesis that overexpression of EMT-TFs indicates a poor prognosis for HNSCC patients.

Introduction The incidence of tongue squamous cell carcinoma (TSCC) has increased in recent decades. However, the function of long non-coding RNA (lncRNA) CASC9 in the occurrence and progression of TSCC is unclear. In this work, we attempted to clarify the role of lncRNA CASC9 in determining the phenotype of TSCC cells, and to clarify the underlying mechanisms. Methods We used qRT-PCR analysis to identify the level of CASC9 mRNA expression in TSCC clinical samples and cell lines. We investigated cell proliferation, and cell migration and invasion of TSCC cells transfected with siCASC9 or siNC using CCK-8 and transwell assays. Bioinformatics analysis and a luciferase reporter assay were employed to predict and verify the target microRNA (miRNA). Results CASC9 was up-regulated in the TSCC tissues and cells, and predicted a poor prognosis. CASC9 silencing significantly inhibited cell proliferation, migration, and invasion of the TSCC cells compared with the non-targeting control small interfering RNA (siCtrl) treatment. miR-423-5p was predicted as the targeting miRNA of CASC9; this was verified by a luciferase reporter assay. CASC9 expression showed a negative correlation with miR-423-5p expression and a positive correlation with SOX12 expression. The miR-423-5p inhibitor can rescue the carcinogenesis effect of CASC9 on TSCC cells. Conclusion Our work indicates that CASC9 plays a role in TSCC tumorigenesis; this novel information will improve TSCC molecular targeting therapy.

Abstract
Surgical options for treating early tongue squamous cell carcinoma and patient survival were explored. Clinical records of 128 patients with early tongue squamous cell carcinoma who were treated in Henan Province Hospital of TCM from June, 2010 to June, 2013 were retrospectively analyzed. According to adopted treatment plan, the patients were divided into 3 groups: 42 patients in surgical therapy alone group, 46 patients in preoperative radiotherapy group, and 40 patients in postoperative radiotherapy group. Statistical analysis was performed on the general data of patients and clinical records, as well as the 5-year survival rate and recurrence rate. The overall 5-year survival rate for all patients was 86.7% (111/128), and the 5-year disease-specific survival rate was 88.8% (111/125). In the individual groups, the 5-year survival rate and the 5-year disease-specific survival rate were 91.3% (84/92) and 91.3% (84/92), respectively, in the surgical therapy alone group 76.9% (10/13) and 83.3% (10/12), respectively, in the preoperative radiotherapy group, and 73.9% (17/23) and 81.0% (17/21), respectively, in the postoperative radiotherapy group. There were no statistically significant differences in 5-year survival rate (χ2=5.990, P=0.051) and 5-year disease-specific survival rate (χ2=2.223, P=0.329) among the three groups. In total, there were 25 cases of recurrence during follow-up. The recurrence rate was 19.5%; the local recurrence rate was 11.7% (15/128); and the regional recurrence rate was 7.8% (10/128). There were 6 cases of metastasis, and the metastatic rate was 4.7%. There were no statistically significant differences in recurrence rate and metastatic rate among the three groups. Compared with surgical therapy alone, radiotherapy combined with surgical therapy neither improved 5-year survival rate nor reduced recurrence rate. Therefore, surgical therapy alone is suggested to be the preferred option for treating early tongue squamous cell carcinoma.

Abstract
Transoral salivary fistulas are one of the most serious postoperative complications after operations for oral cancer, and we propose a new, two-step suture method to avoid them. From January 2005 to September 2017, 240 patients were recruited at the Shanghai Ninth People's Hospital and divided into experimental (n=89) or control (n=151) groups. The experimental group was treated by a two-step suture technique, while the control group had conventional sutures. Statistical differences were assessed using the chi squared and t tests, as appropriate. Only two patients developed transoral salivary fistulas in the experimental group, while in the control group there were 14 (9%). The incidence of fistulas in the experimental group was significantly lower than that in the control group (p=0.035). Regression analysis showed that there was a significant correlation between the groups and the incidence of salivary fistulas (p=0.032). The two-step suture technique is safe, effective, and easy to learn, and could reduce the incidence of postoperative salivary fistulas.

Abstract
Autophagy modulation is a potential therapeutic strategy for tongue squamous cell carcinoma (TSCC). Melatonin possesses significant anticarcinogenic activity. However, whether melatonin induces autophagy and its roles in cell death in TSCC are unclear. Herein, we show that melatonin induced significant apoptosis in the TSCC cell line Cal27. Apart from the induction of apoptosis, we demonstrated that melatonin-induced autophagic flux in Cal27 cells as evidenced by the formation of GFP-LC3 puncta, and the upregulation of LC3-II and downregulation of SQSTM1/P62. Moreover, pharmacological or genetic blockage of autophagy enhanced melatonin-induced apoptosis, indicating a cytoprotective role of autophagy in melatonin-treated Cal27 cells. Mechanistically, melatonin induced TFE3(Ser321) dephosphorylation, subsequently activated TFE3 nuclear translocation, and increased TFE3 reporter activity, which contributed to the expression of autophagy-related genes and lysosomal biogenesis. Luzindole, a melatonin membrane receptor blocker, or MT2-siRNA partially blocked the ability of melatonin to promote mTORC1/TFE3 signaling. Furthermore, we verified in a xenograft mouse model that melatonin with hydroxychloroquine or TFE3-siRNA exerted a synergistic antitumor effect by inhibiting autophagy. Importantly, TFE3 expression positively correlated with TSCC development and poor prognosis in patients. Collectively, we demonstrated that the melatonin-induced increase in TFE3-dependent autophagy is mediated through the melatonin membrane receptor in TSCC. These data also suggest that blocking melatonin membrane receptor-TFE3-dependent autophagy to enhance the activity of melatonin warrants further attention as a treatment strategy for TSCC.

Abstract
OBJECTIVE Resection of posteriorly located oral squamous cell carcinomas (OSCCs) remains challenging for head and neck surgeons. However, several surgical techniques, such as lip and mandibular splitting, as well as submental "visor drop-down" of intraoral soft tissues, have been proposed for this purpose. Merrick et al. suggested that a pedicled genial drop-down surgical approach should be used to resect dorsally located OSCCs. Our study investigated patient outcomes following this surgical procedure, as no previous study has analyzed long-term follow-up data. MATERIAL AND METHODS All patients who underwent surgery using the pedicled genial "visor drop-down" approach at the Maxillofacial Department of the University Hospital Giessen in Germany between 1995 and 2010 were included in this study. In addition, our study required that patients diagnosed with OSCC had no history of other intraoral malignancy or any other form of malignancy. A preliminary questionnaire was completed for each patient based on retrospective analysis of available data from medical reports. RESULTS A total of 51 patients fulfilled all inclusion and exclusion criteria and were evaluated retrospectively. In total, 32 patients were excluded from the study due to OSCC recurrence or acquisition of a different type of malignancy. The male to female distribution of patients in our study was 30 to 21 (58.8%-41.2%), and the mean ages of female and male patients were 57.7 (SD 14.3) and 55.7 (SD 14.4) years, respectively. Approximately 76.5% of tumors were located along the dorsal aspect of the tongue, 17.6% were along the floor of the mouth, 3.9% were in the dorsal mandibular region, and 1.9% were in the dorsal palatal region. The mean overall operation time was 6.25 h, and 28 patients received microvascular flaps for reconstruction. Results of final histopathological examination suggested primary in-sano resection of the tumor in 84.3% of patients. Overall, the 5-year postoperative survival rate was 52.9%; 31.3% of the patient cohort was not followed up for the full 5-year period. In addition, 15.7% of the patients included in our study died during the study period. Unimpaired functional outcomes in terms of swallowing and speech were observed in 86.3% of patients. CONCLUSION The pedicled genial "visor drop-down" approach, also known as the ex corpore linguae, is a suitable method for the radical resection of dorsally located OSCCs, with a promising 5-year survival rate and satisfactory postoperative oral function.

Abstract
Oral tongue squamous cell carcinoma (OTSCC) is the most common oral malignancy with different histopathological symptoms and etiology of tumorigenesis. Migration and invasion is the most important characteristics of OTSCC, and limits tumor therapy in clinics. The epithelial‑to‑mesenchymal transition (EMT) signaling pathway is an important process in the progress of tumor cell migration and invasion. Previous studies have indicated that C‑X‑C chemokine receptor‑7 (CXCR‑7) promotes the progression and metastasis of tumor cells, presenting a potential target molecule for cancer therapy. The present study investigated the inhibitory effects of C‑X‑C chemokine‑7 (CXC‑7) on human OTSCC cells both in vitro and in vivo. The results demonstrated that the Tca8113 human OTSCC cell line expressed higher levels of CXC‑7 mRNA compared with the hNOE human normal oral epithelial cell line. MTT assays indicated that CXC‑7 suppressed Tca8113 cell growth, and the cytotoxicity of CXC‑7 was indicated as the cell survival of the negative control group was significantly decreased compared with the blank control and hNOE cells. Migration and invasion assays revealed that CXC‑7 inhibited Tca8113 cell local expansion and distant metastasis. In addition, the results demonstrated that the extracellular signal‑regulated kinase (ERK)/protein kinase B (AKT) signaling pathway was inhibited after CXC‑7 treatment in Tca8113 cells. N‑cadherin, E‑Cadherin, Snail and Slug expression levels in the ERK/AKT signaling pathway were inhibited in Tca8113 cells after treatment with CXC‑7. It was demonstrated that important extracellular matrix proteins involved in cell migration, including Slug, collagen type I and Vimentin, were significantly downregulated by CXC‑7 treatment. In conclusion, CXC‑7 inhibited growth and migration in OTSCC cells, mediated by the EMT signaling pathway. This suggests that CXC‑7 serves an inhibitory role in OTSCC migration, implicating CXCR‑7 as a promising biomarker for chemokine receptor‑based drug development.

Abstract
BACKGROUND Tongue resection is a surgical challenge because of its adverse effects on language articulation, swallowing, respiration, the eventual quality of life, and poor prognosis of advanced disease. To date, the currently accepted standard treatment has been based on excision of the primary lesion with a 1.5-2-cm circumferential macroscopic margin. Compartmental tongue surgery (CTS) is a surgical technique that removes an anatomo-functional compartment containing the primary tumor. METHODS AND TECHNIQUES This is a prospective study that was carried out from June 2012 to January 2015 for patients with carcinoma affecting oral tongue. We enrolled all cases with ≥T2 tongue cancer with or without infiltration of floor of the mouth. Patients underwent compartmental tongue resection with reconstruction using island submental flap. RESULTS Pharyngeal tear occurred in two cases that were repaired by simple suture. Bleeding occurred in two cases with control of the affected vessels. Loco-regional recurrence was detected only in two cases that underwent CTS, while 18 patients who underwent traditional tongue resection had local recurrence. CONCLUSION CTS via pull through technique with submental island flap reconstruction for large tongue cancer has been evolved to improve oncologic resections, obtaining a better local control of disease and increased survival rate with concomitant successful functional and esthetic outcomes especially in elderly patients with serious comorbidities.

Abstract
This study characterized the infiltration of primary tumors along the muscles, fascia and spaces of the maxillofacial region in buccal squamous cell carcinoma (BSCC) and suggested a new surgical strategy that is suitable for most stages. Based on the anatomic characteristics and infiltration of the primary tumor a new surgical approach - unit resection buccal surgery (URBS) - was developed. We evaluated this new surgical strategy, across a cohort of 127 BSCCs: 60 cases treated with URBS and 67 cases treated with conventional surgery. Notably there was no statistical difference in the clinicopathological variables between the two groups. After initial treatment with curative intent, the patients were regularly followed-up with clinical examination and imaging. URBS proved suitable for almost all stages of BSCC, and was particularly advantageous for advanced stages of BSCC. At 2 years post-treatment, the rates of overall survival were 83.3% in the URBS group and 60.1% in the conventional surgery group, respectively (hazard ratio 0.38; 95% CI 0.20 to 0.75; P=0.005). Similarly, the rates of disease-free survival were 76.6% and 51.9% in the URBS group and the conventional surgery group, respectively (hazard ratio 0.42; 95% CI 0.23 to 0.75; P=0.003). The principles of URBS are suitable for almost all stages of BSCC, especially advanced stages. URBS may improve the prognosis of BSCC patients.

Abstract
CD73 is a cell surface immunosuppressive enzyme involved in tumor progression and metastasis. While patients whose cancer cells express elevated CD73 are typically associated with an unfavorable outcome, the clinical impact of CD73 expression in patients with Head and neck squamous cell carcinoma (HNSCC) remains unclear. In the present study, we investigated the prognostic significance of CD73 in HNSCC using gene and protein expression analyses. Our results demonstrate that high levels of CD73 are significantly associated with reduced overall survival in patients with HNSCC. We also investigated the functional role of CD73 in vitro and demonstrated that CD73 promotes HNSCC migration and invasion through adenosine A3R stimulation and the activation of EGF/EGFR signaling. Moreover, in vivo xenograft studies demonstrated that CD73 promotes tumorigenesis. In conclusion, our study highlights a role for CD73 as a poor prognostic marker of patient survival and also as a candidate therapeutic target in HNSCCs.

Radiochemotherapy for locally advanced squamous cell carcinoma of the head and neck: Higher-dose cisplatin every 3 weeks versus cisplatin/5-fluorouracil every 4 weeks. J Craniomaxillofac Surg 2016; 44:1436-40. [PMID: 27499514 DOI: 10.1016/j.jcms.2016.06.033] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2016] [Revised: 05/27/2016] [Accepted: 06/29/2016] [Indexed: 11/20/2022] Open
Abstract
Many patients with locally advanced squamous cell carcinoma of the head and neck (LASCCHN) receive cisplatin-based radiochemotherapy. The optimal regimen is still unclear when considering both efficacy and feasibility. This study compared two regimens for locoregional control (LRC), overall survival (OS), and adverse events. Data of 329 patients with LASCCHN receiving definitive or postoperative radiochemotherapy were retrospectively analyzed. A total of 131 patients received 100 mg/m(2) cisplatin on days 1, 22, and 43 (group A), and 198 patients received 20 mg/m(2) cisplatin plus 600/1000 mg/m(2) 5-FU on days 1-5 and days 29-33 (group B). Radiochemotherapy regimens plus nine factors were compared for LRC and OS, and radiochemotherapy regimens additionally for adverse events. On univariate analysis, chemotherapy type was not associated with LRC (p = 0.36). On multivariate analysis, performance score (p = 0.039), N-category (p = 0.007), histologic grade (p = 0.007), upfront surgery (p = 0.030), and pre-radiochemotherapy hemoglobin levels (p < 0.001) were associated with LRC. On univariate analysis, chemotherapy type had no impact on OS (p = 0.64). On multivariate analysis, performance score (p < 0.001), T-category (p = 0.025), N-category (p < 0.001), histologic grade, and hemoglobin levels (p < 0.001) were associated with OS. Renal failure occurred significantly more often in group A (p = 0.008). Otherwise, adverse events were not significantly different. Thus, both radiochemotherapy regimens appeared similarly effective for LASCCHN. Patients receiving 100 mg/m(2) of cisplatin require close monitoring of their renal function.

Abstract
Objective The objective of this study was to review the published literature and investigate whether E-cadherin gene is a prognostic factor in head and neck squamous cell carcinoma by conducting a meta-analysis. Methods Studies were identified from the databases Embase, Medline, and Cochrane Library by using the keywords “E-cadherin gene” and “head and neck cancer”. Overall survival (OS) and disease-free survival (DFS) were the primary outcome measurements. Results Our literature review identified 1,458 articles; 19 studies with a total number of 2,012 cases were eligible for inclusion in the meta-analysis. The hazard ratio (HR) for OS of patients with decreased expression of E-cadherin gene was 0.57 (95% CI =0.37, 0.89; P=0.000). However, statistical heterogeneity was unacceptably high (I2=74.5%, P=0.000). After sensitivity analysis, heterogeneity became acceptable, and the effect measure was still significant (I2=7.0%; HR =0.52; 95% CI =0.40, 0.66; P=0.000). The HR for DFS was 0.53 (95% CI =0.42, 0.67; P=0.000). Conclusion This meta-analysis showed clear evidence that high E-cadherin gene expression is a positive prognostic factor of head and neck squamous cell carcinoma, resulting in better OS and DFS. However, this conclusion must be interpreted with caution due to a few limitations.

Ren ZH, Zhang CP, Ji T. Expression of SOX2 in oral squamous cell carcinoma and the association with lymph node metastasis. Oncol Lett 2016; 11:1973-1979.

Abstract
Oral squamous cell carcinomas (OSCCs) are a growing problem in the world. The various existing treatments have not markedly improved the survival rate of patients with OSCC during the past three decades. Novel treatment strategies are required. Sex determining region Y-box 2 (SOX2) is a transcription factor that is involved in the maintenance of embryonic stem cell pluripotency and in multiple developmental processes. SOX2 expression was indicated to act as a prognostic factor in various types of tumors, including breast, colorectal, gastric and lung cancer and glioblastoma, and as a link between malignancy and stemness. Cancer stem cells (CSCs) may be responsible for the genesis, growth and metastatic spread of tumors. The poor survival outcomes for OSCC patients may be attributable to a poor selection of target cells for treatment, as current oral cancer therapies are generally aimed at the global mass of tumor. Therefore, the consideration that novel approaches to oral cancer may be targeted using SOX2 and CSCs appears reasonable. In order to better understand the oncogenic roles and the corresponding signal transduction pathways of the SOX2 protein, the present study emphasizes the role of SOX2 in OSCC, including the proteins associated with OSCC, and reviews the literature regarding the role of SOX2 in lymph node metastasis. The aim of the present study is to provide a reference for future studies that engage in research on the aforementioned subject.
