ConclusionThe expression of matrix metalloproteinases-2 and 9 in hypopharyngeal carcinoma was significantly higher than that in pericarcinoma tissue, and it was enhanced with the increase of clinical stage. The expression level was related to lymph node metastasis and tumor pathological stage. Thus, matrix metalloproteinases-2 and 9 may be involved in the occurrence, development, invasion and metastasis of hypopharyngeal carcinoma through a variety of mechanisms.ResumoIntroduçãoA função da metaloproteinase da matriz 2 e9 nas metástases e no desenvolvimento de carcinoma hipofaríngeo...

Conclusion.Compared with SCCHN, SmCCHN carries a worse survival and is more likely to present with more advanced stage.Implications for Practice.Small cell carcinoma of the head and neck (SmCCHN) is a rare subtype of head and neck cancer. In this Surveillance, Epidemiology, and End Results (SEER) data analysis, the characteristics and survival of SmCCHN are compared with those of the common squamous cell carcinoma of the head and neck. Results show that SmCCHN carries a worse prognosis and tends to present at a more advanced stage; SmCCHN also is ten times more likely to originate from the salivary glands. These findings m...

Authors: Wang G, Li X, Li L, Liu D, Sun R, Zhang Q, Geng C, Gong H, Gao X Abstract Clinical value of ultrasonic imaging in diagnosis of hypopharyngeal cancer with cervical lymph node metastasis was investigated. Eighty-nine patients who were diagnosed with hypopharyngeal cancer in Qilu Hospital of Shandong University (Qingdao) from January 2014 to June 2016 were retrospectively analyzed. Sixty-eight patients were diagnosed with hypopharyngeal cancer with cervical lymph node metastasis by pathological sections. Twenty-one patients did not have cervical lymph node metastasis. All the patients were diagnosed by palpat...

ConclusionIn summary, our deactivation model of MALAT1 disentangled the active function of it as a regulator of gene expression governing the hallmarks of laryngeal and hypopharyngeal cancer. Blocking this long non-coding RNA may restrain the development of laryngeal cancer.

Boffetta P, Hashibe M Abstract Head and neck cancer (HNC) risk prediction models based on risk factor profiles have not yet been developed. We took advantage of the large database including 14 studies (1981-2010) in the US from the International Head and Neck Cancer Epidemiology (INHANCE) Consortium to develop risk prediction models. Seventy percent of the data were used to develop HNC risk prediction models; the remaining 30% were used to validate the models. We used competing risk models to calculate absolute risks. The predictors included age, sex, education, race/ethnicity, alcohol drinking intensity, cigarett...

In this study, we found that 3-phosphoinositide-dependent protein kinase 1 (PDK1 or PDPK1) was overexpressed in HSCC. The overexpression was positively correlated lymph node metastasis, clinical stage, and distant metastasis and indicated poor outcome. Loss and gain-of-function revealed that PDK1 increased cell proliferation, migration and invasion in vitro as well as tumor growth and metastasis in vivo. Mechanically, PDK1 induced epithelial-mesenchymal transition and promoted metastasis by activating the Notch1 signaling pathway. We further illustrated that PDK1 bound with the Notch1 intracellular domain, thereby inhibiti...

Lateral neck masses may be due to congenital, infectious, or malignant disease. Sometimes, the mass can be the only sign of an asymptomatic cancer. A correct clinical approach and the differential diagnosis are the key points for a correct diagnosis. AbstractLateral neck masses may be due to congenital, infectious, or malignant disease.

This study aimed to test the role of Cx43 protein on Bcl-2 expression, tumor progression and response to taxane-based treatment in HNSCC. Human papillomavirus (HPV) negative HNSCC cell lines were tested for paclitaxel sensitivity through measuring apoptosis induction, cell viability and changes in Cx43 and Bcl-2 levels using flow cytometry, cell viability assay, immunocytochemistry and western blot. Inhibition of Cx43 expression using siRNA increased Bcl-2 protein levels in SCC25 (tongue squamous cell carcinoma) cells, while forced Cx43 expression reduced Bcl-2 levels and supported paclitaxel cytotoxicity in FaDu (hypophar...

Authors: Vahl JM, Schuler PJ, Greve J, Laban S, Knopf A, Hoffmann TK Abstract Total laryngectomy provides a curative approach for patients with advanced laryngeal and hypopharyngeal cancer without distant metastasis. Especially in stage cT4a disease, laryngectomy is superior to primary radio(chemo)therapy in retrospective studies. Further relevant indications for the procedure are tumor-related laryngeal dysfunction such as dysphagia and aspiration, as well as cancer recurrence after primary radio(chemo)therapy. The surgical procedure is highly standardized, with an appropriate safety profile. The subsequent l...
