Basaloid squamous cell carcinoma (BSCC) is a rare, aggressive and distinct variant of squamous cell carcinoma (SCC) of the upper respiratory and digestive tract. We have evaluated disease specific survival (DSS) and overall survival (OS) through Kaplan-Meier method and mortality risk through univariate statistical analysis of Cox in 42 cases of BSCC and other 42 of laryngeal SCC (LSCC) matched for both age and sex. We demonstrated that laryngeal BSCC is a more aggressive tumor than LSCC as is associated to higher nodal recurrence of pathology (5 vs 2 patients, overall risk, OR 2...

BACKGROUND/PURPOSE: To present a case report of retinal metastasis of laryngeal squamous cell carcinoma that was diagnosed by a histopathologic finding from the surgically extracted tumor tissue. METHODS: A 66-year-old man, who was suffered from the treatment-resistant laryngeal carcinoma, was referred to our department because of visual field defect in his right eye. A fundus examination revealed a parafoveal white retinal lesion, which rapidly expanded to the central fovea and decreased the visual acuity...

BACKGROUND: Transoral videolaryngoscopic surgery (TOVS) has been widely applied for early T stage head and neck cancer. The resection is performed with a minimum safety margin for function preservation under a limited surgical field of view, making it difficult to be certain of complete resection. OBJECTIVE: Our aim is the evaluation of the completeness of resection by initial TOVS resection, and the possibility of primary control by TOVS alone, allowing for repeat procedures for function preserving treatment in early T stage laryngeal, oropharyngeal, and hypopharyngeal cancer patients...

OBJECTIVE: Lymph node ratio (LNR) was shown to be a prognostic factor in laryngeal and oral cavity primaries. The purpose of this study was to investigate the impact of the lymph node ratio in oropharyngeal squamous cell carcinoma (OPSCC) with a high incidence of HPV-related disease. Therefore, the role of LNR was evaluated as an additional predictive parameter to the 8th edition of AJCC TNM staging system. METHODS: From December 2009 to August 2015, patients diagnosed with primary oropharyngeal squamous cell carcinoma were prospectively enrolled...

Background: Lymphoepithelial carcinoma is a tumor mostly diagnosed in the nasopharynx, but it has also been described in a variety of nonnasopharyngeal sites. It is extremely rare in the larynx and should be distinguished from squamous cell carcinoma. Therefore, it must be known by clinicians, pathologists and oncologists. In this case report, we discuss its etiopathogeny, its epidemiological, clinical, pathological and therapeutic aspects, and its outcome. Case presentation: An 81-year-old Morrocan man, smoker for 40 years, presented with a 1 year history of dysphonia, dyspnea and dysphagia...

Introduction: CA 19-9 is used as a tumor marker in colon, pancreas, biliary, and gastric cancers. Laryngeal cancer is the most common malignant epithelial tumor among head and neck cancers and has no specific tumor marker. Case report: A 66-year-old male patient had severe reflux symptoms during 5 years and had an isolated CA 19-9 elevation. Follow-up analysis revealed that he had larynx cancer and after laryngectomy, CA 19-9 levels decreased to normal range. Discussion: Currently, CA 19-9 is not a marker for malignancy...

OBJECTIVES: Salvage surgery is the gold-standard treatment for locoregional recurrence of laryngeal and hypopharyngeal cancer following radiation therapy. Imperfect oncologic and functional results, however, require patient selection. The main objective of the present study was to determine preoperative factors for survival. Secondary objectives were to study 5-year overall and disease-free survival, general and locoregional complications, and functional results in terms of feeding and tracheotomy closure...

Large cell neuroendocrine carcinoma (LCNEC) of the larynx is an aggressive form of neuroendocrine carcinoma that affects smokers at an average age of 60 years. LCNEC is characterized by large cells with round to ovoid nuclei distributed in a trabecular or nested growth pattern. Previously, laryngeal LCNEC and atypical carcinoid tumors were considered synonymous; however, laryngeal LCNEC has been shown to have higher mitotic rates and worse prognosis, which has led to laryngeal LCNEC to be separated from atypical carcinoid and classified as a poorly differentiated neuroendocrine carcinoma in the most recent World Health Organization classification...

The costimulatory signals CD28 and B7 have been shown to control tumor invasion and metastasis by regulating T cell activation, whereas the distribution characteristics of B7-associated proteins in laryngeal carcinoma (LC) tissue are still unclear. Here, the expression of members of the B7 superfamily, including B7-H1 (PD-L1), B7-DC (PD-L2) and B7-H4, in fifty-two LC samples was determined by immunohistochemistry, and the relationship between B7-H4 and epithelial-mesenchymal transition (EMT)-associated markers was further assessed by immunofluorescence double staining...

Late detection and lack of standard treatment strategies in larynx cancer patients result in high levels of mortality and poor prognosis. Prognostic stratification of larynx cancer patients based on molecular prognostic tumor biomarkers may lead to more efficient clinical management. Krüppel-like factor 4 (KLF4) and Heat Shock Protein 27 (HSP27) have an important role in tumorigenesis and are considered promising candidate biomarkers for various types of cancer. However, their role in larynx carcinoma remains to be elucidated...

Radioresistance (inherent or acquired) remains a major obstacle affecting the clinical outcome of radiotherapy for laryngeal carcinoma. Results from our laboratory and other groups suggest that aberrant glycosylation contributes to cancer acquired radioresistance. However, the role of glycosylation in inherent radioresistance of laryngeal carcinoma has not been fully uncovered. In this study, we investigated the glycan profiling of the inherent radioresistant (Hep-2max) and radiosensitive (Hep-2min) cell lines using lectin microarray analysis...

Squamous cell carcinomas of the head and neck (SCCHN) affect anatomical sites including the oral cavity, nasal cavity, pharynx, and larynx. Laryngeal cancers are characterized by high recurrence and poor overall survival, and currently lack robust molecular prognostic biomarkers for treatment stratification. Using an algorithm for integrative clustering that simultaneously assesses gene expression, somatic mutation, copy number variation, and methylation, we for the first time identify laryngeal cancer subtypes with distinct prognostic outcomes, and differing from the non-prognostic laryngeal subclasses reported by The Cancer Genome Atlas (TCGA)...

Expression of DCUN1D1 in laryngeal squamous cell carcinoma(LSCC) and its inhibition by small interfering RNA(siRNA) target in the TU-177 cells was investigated. Immunohistochemistry was used to detect the expression level of DCUN1D1 in LSCC tissue in 140 cases and analyze its relationship with clinical pathological characteristics. siRNA expression plasmid targeting DCUN1D1 was constructed and transferred into TU-177 cells. The effect of siRNA target DCUN1D1 gene silencing on proliferation, invasion and migration of TU-177 cells were observed by MTS assay and Transwell experiment...

Dedifferentiated chondrosarcoma of the larynx is a rare and highly malignant tumor. We present the report of a 59-year-old man with dedifferentiated laryngeal chondrosarcoma, which was difficult to diagnose even under microscopic examination. The original diagnosis was an aneurysmal bone cyst, and the final diagnosis was established only after careful consideration of the imaging, surgical, and microscopic findings. In clinical practice, there are many similarities between dedifferentiated chondrosarcoma and aneurysmal bone cysts...

The authors present a case of an 80-year-old Caucasian male with multiple gastric and rectal metastases from malignant melanoma presenting with hypochromic anemia as the sole symptom of disease without evidence of cutaneous and ocular tumor localization. The patient had a medical history positive for malignant lentigo melanoma of the occipital region of the scalp and early stage laryngeal squamous cell carcinoma and prostatic carcinoma treated with radiation therapy. The authors make some considerations on intestinal involvement by metastatic melanoma and discuss the choice of not treating with endoscopic procedures the gastric metastatic lesions most likely responsible for the clinical sign present at diagnosis...

We evaluated the efficacy of dose de-escalation to the normal larynx using conformal radiotherapy (CRT) for T1/T2 glottic cancer. For conventional RT (2DRT, n = 38), the laryngeal box received a median equivalent dose in 2 Gy fractions (EQD2) of 66 Gy. For CRT (n = 42; 3D-CRT, 20; intensity-modulated RT, 22), clinical target volume (CTV)1 (gross tumor with a 3-mm margin) and CTV2 (laryngeal box) received median EQD2s of 66.6 Gy and 52.2 Gy, respectively. With a 71-month median follow-up, five-year local control and overall survival rates for 2DRT vs...

Laryngeal squamous cell carcinoma (LSCC) is one of the most common head and neck cancer, with high mortality and incidence. MicroRNA-26a (miR-26a) is involved in the development and progression of several tumors. However, the roles of miR-26a and its target CKS2 in LSCC progression are not yet clear. The mRNA and protein expression was determined using RT-PCR and Western blotting assay, respectively. Cell proliferation was detected using a Cell Counting kit-8 assay (CCK-8). Transwell assay was used to evaluate cell migration and invasion...
