m Eun Jung Dendrobii Herba is an herbal medicine that uses the stems of Dendrobium species (Orchidacea). It has been traditionally used to treat fever, hydrodipsomania, stomach disorders, and amyotrophia. In our previous study, a bibenzyl compound, moscatilin, which is isolated from Dendrobii Herba, showed potent cytotoxicity against a FaDu human pharyngeal squamous carcinoma cell line. Prompted by this finding, we performed additional studies in FaDu cells to investigate the mechanism of action. Moscatilin induced FaDu cell death by using 5 μM of concentration and by mediating apoptosis, whereas cell prol...

Formononetin induces apoptotic cell death through the suppression of mitogen‑activated protein kinase and nuclear factor‑κB phosphorylation in FaDu human head and neck squamous cell carcinoma cells. Oncol Rep. 2019 Dec 13;: Authors: Oh JS, Kim TH, Park JH, Lim H, Cho IA, You JS, Lee GJ, Seo YS, Kim DK, Kim CS, Yu SK, Kim HJ, Kim SG, Kim JS Abstract Formononetin, a phytoestrogen extracted from various herbal plants, has been investigated as an anticancer agent against diverse types of cancer. The aim of the present study was to investigate the induction of apoptotic cell death by formononetin ...

AbstractPositron emission tomography/computed tomography (PET/CT) has shown prognostic significance in head and neck cancer patients. The underlying pathologic features that could explain the mechanisms associated with this observation are not clear. To analyze the correlation between 18-F-fluoro-2-deoxy-d-glucose (18F-FDG) uptake assessed by PET/CT in head and neck cancer and histopathologic prognostic factors. Ninety-nine patients with laryngeal and pharyngeal squamous cell carcinoma were retrospectively reviewed for pretreatment PET/CT measurements, namely standardized uptake value (SUV), metabolic tumor volume (MTV), a...

Abstract Cancer stem cells (CSCs) play a key role in carcinogenesis and progression of head and neck squamous cell carcinomas (HNSCC). The most common markers indicating for CSCs are: CD44, CD24, CD133, ALDH1A1. Our objective was to evaluate the prognostic potential of CSC markers in HNSCC. The study included 49 patients treated for primary HNSCC, 11 patients with upper respiratory tract epithelial dysplasia and 12 subjects with the normal pharyngeal mucosa as a control group. The frequency and expression levels of the four CSC markers were assessed by immunohistochemistry. Univariate and multivariate analyses wer...

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.

ConclusionThis preliminary study demonstrated PG2 injection exhibited an excellent safety profile, and has potential in ameliorating the deterioration in QoL and the AEs associated with active anticancer treatment among patients with advanced pharyngeal or laryngeal HNSCC under CCRT. Further research in patients with other cancer types or treatment modalities may widen PG2 ’s application in clinical settings.

Conclusion: The majority of parotid SCC are metastases. In cases without known primary lesion and lack of infiltrative tumour growth, a carcinoma with unknown primary should be considered.

This study investigates the prognostic significance of active SRC expression in a homogeneous cohort of 122 human papillomavirus (HPV)-negative, surgically treated HNSCC patients. Immunohistochemical evaluation of the active form of SRC by means of anti-SRC Clone 28 monoclonal antibody was specifically performed and subsequently correlated with clinical data. The expression of p-SRC (Tyr419), total SRC, and downstream SRC effectors was also analyzed. Our results uncovered striking differences in the prognostic relevance of SRC expression in HNSCC patients depending on the tumor site. Active SRC expression was found to sign...

Authors: Chen D, Fan N, Mo J, Wang W, Wang R, Chen Y, Hu J, Wen Z Abstract Background: Patients with esophageal cancer (EC) frequently have multiple primary cancers. We conducted the present study to assess the risk of multiple primary malignancies for patients with squamous cell carcinoma (SCC) and adenocarcinoma (AC) of the esophagus and to investigate the influence of multiple primary tumors on the prognosis of EC patients. Methods: Using the data of 44,091 EC patients from the Surveillance Epidemiology and End Results (SEER) database, we calculated the standardized incidence ratios (SIRs) for overall multip...
