<p><strong>Background: </strong>Prognosis for tongue squamous cell carcinoma depends upon lymph node metastasis and the treatment plan depends upon the management of cervical lymph node metastasis.<strong></strong></p><p><strong>Methods: </strong>A prospective analysis of early squamous cell carcinoma oral tongue was done February 2017 to February 2020 in previously untreated and biopsy proven patients with T1-2N0 cancer of tongue and patients with clinically negative nodes on the basis of palpation, ultrasound and computerized tomography (CT) and previously untreated and biopsy proven patients with T1-2N0 cancer of oral cavity. After proper work up, patients were divided into two groups. Group 1 (n=35) patients that underwent a surgical excision of primary tumor with 15mm safe margin and selective neck dissection (level I, II, III), group 2 (n=33) patients that underwent surgical excision of primary tumor with 15 mm safe margin and neck observation. All patients with tumor thickness ≥4 mm were included in this group. </p><p><strong>Results: </strong>The study included 51 (75%) males and 17(25%) female patients. In this study, recurrence was significantly related to tumor thickness (p&lt;0.05) i.e., &gt;4 mm tumor thickness showed significantly higher local recurrence and nodal recurrences. Also, a significantly higher relationship was seen between nodal recurrence and postoperative close surgical margins (p&lt;0.05).</p><p><strong>Conclusions: </strong>Elective neck dissection becomes necessary in patients with T2N0 tumors and tumor thickness of &gt;4 mm as frequency of occult metastasis and recurrence is more in these patients.</p>

Background: Non-coding RNA-activated by DNA damage (NORAD), a novel identified lncRNA, was found to be aberrantly expressed in various types of cancer. This meta-analysis was performed to evaluate the value of lncRNA NORAD as a prognostic biomarker in human cancers. Methods: We searched PubMed, Web of Science, PMC, and Embase databases thoroughly for eligible literatures. Studies which explored the relationship of lncRNA NORAD expression with clinical outcomes in human cancers were included in our meta-analysis. Review Manager version 5.3 and Stata SE 12.0 were used to perform the data analyses. Results: Our meta-analysis results indicated that cancer patients with high lncRNA NORAD expression tended to have unfavorable overall survival (OS) (HR = 1.67; 95% CI, 1.44-1.95; P < 0.00001). Moreover, elevated lncRNA NORAD expression showed a significant relationship with poor tumor grade (OR = 1.61; 95% CI, 1.01-2.56; P = 0.05) and more lymph node metastasis (LNM) (OR = 2.66; 95% CI, 1.60-4.43; P = 0.0002). Conclusions: LncRNA NORAD could serve as a valuable biomarker to predict poor prognosis and LNM in various human tumors.

Several studies have demonstrated that melanoma-derived extracellular vesicles (EVs) are involved in lymph node metastasis; however, the molecular mechanisms involved are not completely defined. Here, we found that EMILIN-1 is proteolyzed and secreted in small EVs (sEVs) as a novel mechanism to reduce its intracellular levels favoring metastasis in mouse melanoma lymph node metastatic cells. Interestingly, we observed that EMILIN-1 has intrinsic tumor and metastasis suppressive-like properties reducing effective migration, cell viability, primary tumor growth, and metastasis. Overall, our analysis suggests that the inactivation of EMILIN-1 by proteolysis and secretion in sEVs reduce its intrinsic tumor suppressive activities in melanoma favoring tumor progression and metastasis.

Abstract Background.—Cytokeratin 7 (CK7) and cytokeratin 20 (CK20) are 2 types of intermediate filament protein. Expression of CK7 is seen in the majority of primary urinary bladder carcinomas. CK20 is restricted to superficial and occasional intermediate cells of the normal urothelium of the bladder. Aberrant CK20 expression has been documented in urothelial carcinoma and has proved useful as an ancillary diagnostic aid for urinary bladder tumor. Our hypothesis is that the pattern of CK7 and CK20 expression in metastatic urothelial carcinoma duplicates the expression of the same markers in the primary tumors. Therefore, immunohistochemical staining of metastatic tumors for these 2 markers may be helpful for differential diagnosis in ambiguous metastatic tumor deposits. Objective.—To determine the concordance of CK7 and CK20 expression in primary bladder urothelial carcinoma and the matched lymph node metastasis. Design.—We studied 26 patients with lymph node metastases who underwent radical cystectomy and bilateral lymphadenectomy for bladder carcinoma. Immunohistochemical staining for CK7 and CK20 was performed on formalin-fixed paraffin-embedded tissues containing primary cancers and lymph node metastases. Results.—In all cases, there was a concordant expression of CK20 in the primary cancer and its matched lymph node metastasis. Twelve cases (46%) showed positive CK20 immunoreactivity in the primary tumor and its matched lymph node metastases, whereas 14 cases (54%) were negative for CK20 in both the primary tumor and lymph node metastasis. All cases showed positive CK7 immunoreactivity in the primary cancers and matched lymph node metastases. Conclusions.—CK20 immunoreactivity is reliably observed in metastases from bladder cancer when the primary tumor expresses CK20.
