Squamous cell carcinoma of the tongue: clinical and morphological analysis of 57 cases and correlation with prognosis

Conclusion: TNM clinical staging and HGM, evaluated in association, may be useful to estimate the prognosis of TSCC. Introdução: O carcinoma de células escamosas oral (CCEO) representa mais de 90% das neoplasias malignas de cabeça e pescoço. Possui prognóstico desfavorável devido à alta frequência de metástase linfonodal e invasão local. Estudos anteriores investigaram parâmetros relacionados com o comportamento biológico do CCEO e sua correlação com o desfecho clínico. Objetivo: Avaliar dados clínicos e morfológicos em casos de carcinoma de células escamosas de língua (CCEL), correlacionando esses achados com o prognóstico. Material e métodos: Cinquenta e sete espécimes de CCEL foram obtidos de pacientes submetidos à excisão cirúrgica em um hospital de referência de Natal, Brasil. Dados clínicos, a exemplo do estágio tumor-linfonodo-metástase (TNM) e do desfecho da doença (DD), foram coletados dos prontuários médicos. Secções histológicas coradas em hematoxilina e eosina foram analisadas quanto à gradação histológica de malignidade (GHM), com base no sistema de Bryne (1998). Resultados: A maioria dos pacientes (38,6%) foi diagnosticada no estágio TNM III, e 57,9% desenvolveram metástase...

AbstractThe natriuretic peptide (NP) system comprises of three ligands, the Atrial Natriuretic Peptide (ANP), Brain Natriuretic peptide (BNP) and C-type Natriuretic peptide (CNP), and three natriuretic peptide receptors, NPRA, NPRB and NPRC. Here we present a comprehensive study of the natriuretic peptide system in healthy murine and human submandibular salivary glands (SMGs). We show CNP is the dominant NP in mouse and human SMG and is expressed together with NP receptors in ducts, autonomic nerves and the microvasculature of the gland, suggesting CNP autocrine signalling may take place in some of these glandular structur...

ABSTRACT Carcinoma cuniculatum (CC), a rare variant of oral squamous cell carcinoma, presents well-differentiated neoplastic epithelial cells infiltrating the underlying submucosal or bone tissues, forming the so-called "rabbit burrows" filled with keratin. A 67-year-old female patient was referred complaining of a painless tumoral mass in the left mandibular body, with several months of evolution. Previous history indicated extraction of the teeth #37 and #38 and diagnosis of chronic suppurative osteomyelitis. A deep incisional biopsy revealed CC. Due to its microscopic features, suggesting an inflammatory or re...

ABSTRACT Squamous cell carcinoma is a malignant neoplasm that affects the structures and tissues of the oral cavity. Interleukins (IL) synthesized from a tumor modulate a cascade reaction that may influence the prognosis of the disease. We aim to investigate in the literature whether interleukins are mediators that negatively or positively influence the prognosis of patients with oral squamous cell carcinoma. A systematic review study was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes (PRISMA) instructions. PubMed (including MedLine), Scopus, Web of Science, SciELO and Latin A...

Lee Fah Yap Ian C. Paterson Head and neck squamous cell carcinoma (HNSCC) is the sixth most common cancer worldwide and includes squamous cell carcinomas of the oropharynx and oral cavity. Patient prognosis has remained poor for decades and molecular targeted therapies are not in routine use. Here we showed that the overall expression of collagen subunit genes was higher in cancer-associated fibroblasts (CAFs) than normal fibroblasts. Focusing on collagen8A1 and collagen11A1, we showed that collagen is produced by both CAFs and tumour cells, indicating that HNSCCs are collagen-rich environments. We then focused on ...
