Abstract
The aim of this work is to clarify the incidence of meningitis/encephalitis in SARS-CoV-2 patients. We conducted an initial search in PubMed using the Medical Subject Headings (MeSH) terms "meningitis," and "encephalitis,", and "COVID-19" to affirm the need for a review on the topic of the relationship between meningitis/encephalitis and SARS-CoV-2 infection. We included case series, case reports and review articles of COVID-19 patients with these neurological symptoms. Through PubMed database we identified 110 records. After removal of duplicates, we screened 70 record, and 43 were excluded because they focused on different SARS-CoV-2 neurological complications. For eligibility, we assessed 27 full-text articles which met inclusion criteria. Seven articles were excluded, and twenty studies were included in the narrative review, in which encephalitis and/or meningitis case reports/case series were reported. Neurological manifestations of COVID-19 are not rare, especially meningoencephalitis; the hypoxic/metabolic changes produced by the inflammatory response against the virus cytokine storm can lead to encephalopathy, and the presence of comorbidities and other neurological diseases, such as Alzheimer's disease, predispose to these metabolic changes. Further study are needed to investigate the biological mechanisms of neurological complications of COVID-19.

Abstract
INTRODUCTION Submandibular sialadenectomy is a part of the classic technique of neck dissection for oral cavity cancers. However, its removal is associated with a reduction in the salivary outflow in many patients, as well as, some uncommon complications such as lingual and hypoglossal nerve injuries. Assessment of the necessity of such maneuvers should be addressed. PATIENTS AND METHODS The data of 105 patients with tongue cancer who underwent neck dissection in the Oncology Center, Mansoura University from January 2008 to March 2019 were reviewed and analyzed retrospectively. RESULTS In all the included patients, whether showing pathologic positive or negative lymph nodes, none showed capsular or parenchymal submandibular gland metastasis except for one patient who showed direct infiltration of the gland by the primary tumor. CONCLUSION Submandibular sialadenectomy may not be indicated as a part of neck dissection in tongue cancer patients. Further research should be conducted to focus on the effect of its preservation on disease-free and overall survival.

Abstract
OBJECTIVES In this study, a meta-analysis was conducted to evaluate the occult lymph node metastasis rate in patients with early-stage (T1-T2) oral tongue squamous cell carcinoma. Also, the correlation between occult lymph node metastasis rate and T2 ratio among T1-T2 or the reported year of each study was analyzed to adjust other confound variables. STUDY DESIGN Literature search. METHODS A systematic computerized search of the electronic databases was carried out for articles published between January 1, 1980, and December 31, 2018, which reported occult nodal metastasis rate in T1 and T2 (separately) tongue cancer patients. Statistical analysis was performed using Comprehensive Meta Analysis version 3.3.070. Publication bias was assessed by the Egger test and Begg funnel plot method. The correlation between occult nodal metastasis rate and T2 ratio or reported year, respectively, was assessed by meta-regression analysis. RESULTS From 19 studies, a total of 1567 cases were included in the meta-analysis. By random effects model, the mean occult cervical lymph node metastasis was 24.4% (95% confidence interval; 0.205-0.248). The meta-regression revealed that the T2 ratio and the reported year of the studies did not have a significant effect on the occult metastasis rate (correlation coefficient = 0.531 and 0.002, respectively, and P = .426 and 0.921, respectively). CONCLUSION The meta-analysis revealed that the early-stage oral tongue squamous cell carcinoma had a rate of 24.4% for occult nodal metastasis. The occult nodal metastasis rate was not significantly affected by neither T2 ratio among T1-T2 nor reported year of the studies.

Abstract
OBJECTIVES The main aim of the present study is to analyze the differences in the clinical behavior of pT1 and pT2 oral squamous cell carcinoma of the oral cavity and the importance of tumor thickness in these groups of patients. METHODS A retrospective analysis was conducted using the records of patients diagnosed with pT1 and pT2 oral squamous cell carcinoma between 2006 and 2015 to identify significant differences between these two groups of patients. Several pathological features such as T-stage, N-stage, tumor thickness, surgical margins, and locoregional failure were analyzed. RESULTS 194 patients were included in this study. Tumor thickness >0.4 cm was significantly related with nodal involvement and overall survival (p < 0.001). T and N stage, tumor thickness, extracapsular spread and surgical margins were associated with poorer outcomes in terms of overall survival (p < 0.001). CONCLUSION Tumor thickness represents an extremely important prognostic factor and to include depth of invasion (DOI) in the staging of oral squamous cell carcinoma will help in the choice of better treatment strategies and to improve overall survival.

Abstract
There is no clear guideline regarding the indication for routine lymph node extirpation and pathologic evaluation during staging of canine oral tumors, despite a relatively high reported nodal metastatic rate for select tumor types. It is particularly unclear if clinicians recommend removal of lymph nodes only when there is confirmation of metastasis, defined as the N+ neck, or if elective neck dissection (END) is routinely recommended to confirm the true pathologic metastatic status of lymph nodes in the clinical N0 neck (no evidence of metastasis on clinical staging with diagnostic imaging or cytology). When clinicians are recommending END as a staging tool to confirm nodal status, there is also ambiguity regarding the surgical extent for subsequent histopathologic evaluation. The objective of this cross-sectional survey study was to determine the current recommendations given by practicing specialists regarding lymph node removal for dogs with oral tumors. Overall, 87 responses were obtained from 49 private practices (56%) and 38 academic institutions (44%). Respondents identified as oncologists (44%, N = 38), soft tissue surgeons (40%, N = 35), and dentists (16%, N = 14). Regardless of tumor type and stage, extirpation and histopathology were most commonly recommended in the clinical N+ neck only. The recommendation to routinely perform END in the N0 neck was significantly associated with tumor type. Bilateral removal of the mandibular and retropharyngeal lymph nodes was recommended more often for oral malignant melanoma (OMM) than for oral squamous cell carcinoma (OSCC; p ≤ 0.0039) or for oral fibrosarcoma (OFSA; p ≤ 0.0007). The likelihood of recommending END increased with increasing tumor size. Academic clinicians were significantly (p < 0.01) more likely to recommend END compared to private practitioners for canine T1-T3 OMM, T3 OSCC, T2 OFSA, and MCT. This study highlights the variability in recommendations for lymph node pathology for dogs with oral tumors. While tumor type and size influenced the decision to pursue END, it was not routinely recommended, even for tumor types with a known propensity for metastasis. Prospective studies are warranted to determine the potential diagnostic and therapeutic value of END in the N0 neck in veterinary patients such that a consensus approach can be made.

Abstract
Objective: Neck management in cT1-2N0 tongue squamous cell carcinoma (SCC) remains controversial. Our goal was to compare the survival difference between PET-CT–guided neck dissection and elective neck dissection (END) for the treatment of cT1-2 tongue SCC. Methods: Patients with surgically treated cT1-2N0 tongue SCC were retrospectively enrolled. These patients were divided into two groups. Group A: The decision of whether to perform neck dissection was mainly based on the results of preoperative PET-CT examinations. Group B: Patients received END treatment without preoperative PET-CT examinations. The study endpoints were regional control (RC) and disease-specific survival (DSS). The Kaplan–Meier method was used to calculate the survival rates. Results: Group A consisted of 66 patients, and 16 patients underwent neck dissection owing to positive PET-CT results. Group B consisted of 169 patients. The 5-year RC rates in group A and group B were 86 and 87%, respectively, and the difference was not significant (p = 0.731). The 5-year DSS rates in group A and group B were 93 and 90%, respectively, and the difference was not significant (p = 0.583). Conclusions: Neck dissection can be safely avoided when the PET-CT scan reveals no neck lymph node involvement.

Abstract
Objectives Whether to perform elective neck dissection (END) or apply the observation (OBS) policy in patients with early‐stage oral squamous cell carcinoma (OSCC) without clinical evidence of cervical lymph node metastasis (cT1/T2N0) remains uncertain. The two most recent meta‐analyses include many studies published before the widespread availability of CT scanning in the 1990s. With the rapid advancement in imaging studies since 1990, the early clinical detection of cervical node metastasis has become more reliable without the need for END or pathological staging. Thus, we conducted a systematic review and meta‐analysis of studies comparing survival outcomes between END and OBS in patients with cT1/T2N0 OSCC. Methods We performed a systematic search of MEDLINE, PubMed, and Scopus for retrospective and prospective studies published between January 1, 1990, and January 1, 2018, comparing clinical outcomes between END and OBS in patients with cT1/T2N0 OSCC. Information on population characteristics, study design, overall survival (OS), disease‐specific survival (DSS), and disease‐free survival (DFS) was extracted and estimated. Effect measures for outcomes were hazard ratios (HRs) and 95% confidence intervals (CIs). Results Thirteen retrospective and two prospective randomized studies (3,158 patients) met the inclusion criteria. Compared to OBS, END failed to significantly improve OS (HR, 1.02; 95% CI, 0.95–1.09; P = .77; fixed‐effects model), DSS (HR, 1.07; CI, 1.02–1.13; P = .31; fixed‐effects model), and DFS (HR, 0.86; CI, 0.72–1.01; P = .12; random‐effects model). Conclusions Our findings indicate that in patients with cT1T2N0 OSCC, the OBS policy can yield markedly similar OS, DSS, and DFS to those resulting from END. Level of Evidence 2

Elective Neck Dissection Versus Wait-and-Watch Policy for Oral Cavity Squamous Cell Carcinoma in Early Stage: A Systematic Review and Meta-Analysis Based on Survival Data. J Oral Maxillofac Surg 2019; 77:2154-2167.

Abstract
PURPOSE Whether elective neck dissection (END) should be adopted for patients with clinically early-stage (cT1-2N0M0) oral cavity squamous cell carcinoma (OCSCC) remains debated. The aim of this systematic review was to compare the survival benefit of END with that of the wait-and-watch policy (WW) for patients with early-stage OCSCC based on survival data. MATERIALS AND METHODS According to the inclusion criteria, an exhaustive search for eligible studies was conducted. The study inclusion and data extraction were performed by 2 reviewers independently. The risk of bias was assessed in duplicate using the Risk Of Bias In Nonrandomized Studies of Interventions instrument. The hazard ratio (HR) of the time-to-event data was extracted or estimated. RevMan 5.3 and STATA 15.1 were adopted for data synthesis. RESULTS Of the 35 studies that were included, only 5 were assessed as having a low risk of bias. Results of the meta-analyses showed END could significantly decrease neck recurrence (relative risk = 0.45; confidence interval [CI], 0.35-0.59; P < .00001) and improve disease-free survival (HR = 0.55; CI, 0.42-0.71; P < .00001), overall survival (HR = 0.75; CI, 0.64-0.86; P < .0001), and disease-specific survival (HR = 0.76; CI, 0.61-0.94; P = .01) compared with WW for patients with cT1-2N0. The subgroup analysis showed that END could decrease neck recurrence (P < .00001) and improve disease-free survival (P = .001) for patients with early-stage tongue cancer and that supraomohyoid neck dissection could decrease neck recurrence (P = .02). For patients with cT1N0, END could significantly decrease the proportion with neck recurrence (P = .0008) and improve disease-free survival (P = .0003), but the difference between overall survival and disease-specific survival did not achieve significance. CONCLUSIONS END can decrease recurrence and improve survival time for patients with early-stage OCSCC. More high-quality studies are needed to make a solid conclusion, especially for patients with cT1N0M0.

Abstract
Nodal metastasis is the single most prognostic determinant in patients with oral squamous cell carcinoma (OSCC). Since its inception more than a century ago, the management of the neck has led to decreased surgical morbidity, with continued preservation of oncologic safety for OSCC. Nodal metastasis is the single most prognostic determinant in patients with OSCC. The decision for the extent of the neck dissection is tailored to tumor-specific characteristics, which dictate the probability and extent of nodal metastasis, including tumor size, location, histopathologic characteristics, and the presence or absence of clinical nodal disease. These factors are tools to aid diagnosticians in their decision making for individual patients.

Abstract
PURPOSE The aim of the current work is to provide evidence-based recommendations to practicing physicians and others on the management of the neck in patients with squamous cell carcinoma of the oral cavity and oropharynx. METHODS ASCO convened an Expert Panel of medical oncology, surgery, radiation oncology, and advocacy experts to conduct a literature search, which included systematic reviews, meta-analyses, randomized controlled trials, and prospective and retrospective comparative observational studies published from 1990 through 2018. Outcomes of interest included survival, regional disease control, neck recurrence, and quality of life. Expert Panel members used available evidence and informal consensus to develop evidence-based guideline recommendations. RESULTS The literature search identified 124 relevant studies to inform the evidence base for this guideline. Six clinical scenarios were devised; three for oral cavity cancer and three for oropharynx cancer, and recommendations were generated for each one. RECOMMENDATIONS For oral cavity cancers, clinical scenarios focused on the indications for and the hallmarks of a high-quality neck dissection, indications for postoperative radiotherapy or chemoradiotherapy, and whether radiotherapy alone is sufficient elective treatment of an undissected neck compared with high-quality neck dissection. For oropharynx cancers, clinical scenarios focused on hallmarks of a high-quality neck dissection, factors that would favor operative versus nonoperative primary management, and clarifying criteria for an incomplete response to definitive chemoradiation for which salvage neck dissection would be recommended. Consensus was reached and recommendations were made for all six clinical scenarios. Additional information is available at www.asco.org/head-neck-cancer-guidelines .

Abstract
To analyze the superiority of wait-and-see policy and elective neck dissection in treating cN0 patients with facial cutaneous cell carcinoma (cSCC).Patients with clinically negative parotid and neck metastasis disease were prospectively enrolled. Three groups were divided based on whether the patient received an operation of superficial parotidectomy or/and elective dissection, and regional control and disease-specific survival rates were compared.The occult parotid and neck metastasis rate was 20% and 16%, respectively. There was neck node metastasis without parotid metastasis in only 1 patient. All the node metastasis occurred in level II. Regional recurrence was noted in 16 (16%) patients, and 6 patients died of the disease. In the group undergoing superficial parotidectomy and elective neck dissection, 2 patients had neck node metastasis, and there was no disease-related death, further survival analysis indicated it had better regional control and disease-specific survival rates compared with the other 2 groups.Superficial parotidectomy and elective neck dissection are suggested for patients with T3-4 facial cutaneous squamous cell carcinoma.

Abstract
OBJECTIVES The purpose of this study was to evaluate the necessity of elective bilateral neck dissection for treating strict unilateral squamous cell carcinoma (SCC) of the tongue. METHODS A cohort of 169 patients with unilateral non-midline crossing SCCs of the tongue treated by local resection and neck dissection was investigated. Study endpoints were nodal relapse and overall survival. The mean follow-up was 7.4 years. RESULTS A total of 146 (88.1%) patients were treated by neck dissection. Lymph node metastases were diagnosed in 50 (34.2%) patients. Only two (1.1%) had contralateral lymph node metastases. Risk factors for developing a primary lymph node metastasis were size of tumor (T2/T3, p = 0.03; OR = 2.2), lymphangiosis (p = 0.003; OR = 4.7), and higher-grade differentiation (p = 0.051; OR = 2.43). Metachronous lymph node metastases were detected in 23 (13.6%) patients (19 ipsilateral, one contralateral and three bilateral). The main risk factor for developing a metachronous lymph node metastasis was the presence of a primary lymph node metastasis (p = 0.004; HR = 4.65). Patients with initial neck dissection came up with lower 5-year recurrence rates (13.6%) compared to patients without neck dissection (27.3%; p = 0.014). Bilateral neck dissection showed no advantage regarding nodal relapse free and overall survival (p = 0.606) compared to unilateral neck dissection irrespective of initial N or T stage. CONCLUSION Patients with unilateral SCC of the tongue benefit from an ipsilateral neck dissection regarding nodal relapse. The value of elective bilateral neck dissection as standard treatment seems questionable even if positive lymph nodes were diagnosed ipsilateral at primary therapy.

Maruyama T, Nishihara K, Umikawa M, Arasaki A, Nakasone T, Nimura F, Matayoshi A, Takei K, Nakachi S, Kariya KI, Yoshimi N. MicroRNA-196a-5p is a potential prognostic marker of delayed lymph node metastasis in early-stage tongue squamous cell carcinoma. Oncol Lett 2017; 15:2349-2363. [PMID: 29434944 PMCID: PMC5778269 DOI: 10.3892/ol.2017.7562] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2017] [Accepted: 11/20/2017] [Indexed: 12/25/2022] Open
Abstract
MicroRNAs (miRs) are expected to serve as prognostic tools for cancer. However, many miRs have been reported as prognostic markers of recurrence or metastasis in oral squamous cell carcinoma patients. We aimed to determine the prognostic markers in early-stage tongue squamous cell carcinoma (TSCC). Based on previous studies, we hypothesized that miR-10a, 10b, 196a-5p, 196a-3p, and 196b were prognostic markers and we retrospectively performed miR expression analyses using formalin-fixed paraffin-embedded sections of surgical specimens. Total RNA was isolated from cancer tissues and adjacent normal tissue as control, and samples were collected by laser-capture microdissection. After cDNA synthesis, reverse transcription-quantitative polymerase chain reaction was performed. Statistical analyses for patient clinicopathological characteristics, recurrence/metastasis, and survival rates were performed to discern their relationships with miR expression levels, and the 2−ΔΔCq method was used. miR-196a-5p levels were significantly upregulated in early-stage TSCC, particularly in the lymph node metastasis (LNM) group. The LNM-free survival rate in the low miR-196a-5p ΔΔCq value regulation group was found to be lower than that in the high ΔΔCq value regulation group (P=0.0079). Receiver operating characteristic analysis of ΔΔCq values revealed that miR-196a-5p had a P-value=0.0025, area under the curve=0.740, and a cut-off value=−0.875 for distinguishing LNM. To our knowledge, this is the first study to examine LNM-related miRs in early-stage TSCC as well as miRs and ‘delayed LNM’ in head and neck cancer. miR-196a-5p upregulation may predict delayed LNM. Our data serve as a foundation for future studies to evaluate miR levels and facilitate the prediction of delayed LNM during early-stage TSCC, which prevent metastasis when combined with close follow-up and aggressive adjuvant therapy or elective neck dissection. Moreover, our data will serve as a foundation for future studies to evaluate whether miR-196a-5p can serve as a therapeutic marker for preventing metastasis.

A retrospective study of 117 oral tongue carcinomas. J Craniomaxillofac Surg 2017; 46:155-161.

Abstract
PURPOSE The aims of this study were to evaluate the pattern of distribution of cervical metastasis in tongue cancer and to analyze the various therapeutic options available. Moreover, numerous histological features were analyzed to assess the impact of each factor on overall survival. MATERIALS AND METHODS A retrospective analysis was conducted using the records of patients diagnosed with oral tongue cancer between 2004 and 2010 in the Virgen de las Nieves University Hospital (HUVN). A total of 117 patients with squamous cell carcinoma of the tongue treated with glossectomy and selective neck dissection were included in the study. The pattern of distribution of cervical metastases and numerous histological features such as T-stage, N stage, surgical margins, tumor thickness, extracapsular spread (ECS) and vascular invasion were analyzed. RESULTS Level IIA was the most affected, followed by level III. The rate of skip metastasis was 7,4%. T and N stage, tumor thickness, ECS, surgical margins and nerve and vascular invasion were associated with poorer outcomes in terms of overall survival (p < 0,001). CONCLUSION Cervical nodal involvement represents the major prognostic factor in tongue cancer. A total of 51,2% of N+ patients presented T1 and T2 tumors in this series. We recommend performing neck dissection at the early stages in clinically N0 patients when a tumor thickness >0,4 cm is suspected. Level IV should be included in the neck dissection of clinically N0 tongue cancer.

Neck observation versus elective neck dissection in management of clinical T1/2N0 oral squamous cell carcinoma: a retrospective study of 232 patients. Chin J Cancer Res 2017; 29:179-188. [PMID: 28729768 PMCID: PMC5497204 DOI: 10.21147/j.issn.1000-9604.2017.03.03] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/30/2022] Open
Abstract
Objective The management of early-stage (cT1/2N0) oral squamous cell carcinoma (OSCC) remains a controversial issue. The aim of this study was to compare the clinical outcomes of neck observation (OBS) and elective neck dissection (END) in treating patients with cT1/2N0 OSCC. Methods A total of 232 patients with cT1/2N0 OSCC were included in this retrospective study. Of these patients, 181 were treated with END and 51 with OBS. The survival curves of 5-year overall survival (OS), disease-specific survival (DSS), and recurrence-free survival (RFS) rates were plotted using the Kaplan-Meier method for each group, and compared using the Log-rank test. Results There was no significant difference in 5-year OS and DSS rates between END and OBS groups (OS: 89.0% vs. 88.2%, P=0.906; DSS: 92.3% vs. 92.2%, P=0.998). However, the END group had a higher 5-year RFS rate than the OBS group (90.1% vs. 76.5%, P=0.009). Patients with occult metastases in OBS group (7/51) had similar 5-year OS rate (57.1% vs. 64.1%, P=0.839) and DSS rate (71.4% vs. 74.4%, P=0.982) to those in END group (39/181). In the regional recurrence patients, the 5-year OS rate (57.1% vs. 11.1%, P=0.011) and DSS rate (71.4% vs. 22.2%, P=0.022) in OBS group (7/51) were higher than those in END group (9/181).
Conclusions The results indicated that OBS policy could obtain the same 5-year OS and DSS as END. Under close follow-up, OBS policy may be an available treatment option for patients with clinical T1/2N0 OSCC.
