OBJECTIVES To examine the impact of epidermal growth factor receptor (EGFR) expression level on the efficacy of monoclonal antibodies against the EGFR. METHODS In four human head and neck carcinoma cell lines, epidermal growth factor expression was knocked down by lentiviral RNA interference. Next, the efficacies of cetuximab and panitumumab at(More)
The present study examined the relationship between MAGE-A tumor antigens and the efficacy of diamindichloridoplatin (DDP), 5-fluorouracil (5-FU), docetaxel, and paclitaxel for in vitro treatment of head and neck cancer. In the present study, five cell lines of human squamous cell carcinomas were treated with DDP (25–400 μM), 5-FU (0.75–12 mM), docetaxel(More)
The nonsurgical treatment of head and neck squamous cell carcinoma (HNSCC) usually consists of radiation and chemotherapy. In general, the treatment efficacy of chemotherapy in head and neck cancer is limited. Apart from the placenta, testis and fetal keratinocytes, melanoma-associated antigens-A (MAGE-A) are only found in malignancies. Even though their(More)
BACKGROUND Over-expression of epidermal growth factor receptor (EGFR) has been observed in a variety of epithelial tumours. The selective inhibition of the associated signalling pathway using monoclonal antibodies appears to be a promising therapeutic target. Individual differences in response rates, particularly against highly selective chemotherapeutic(More)
PURPOSE In oral cancer and in other tumor entities, melanoma-associated antigens are present. These antigens contribute to tumor progression and poor prognosis, and reduce the cytotoxicity of antineoplastic drugs. The aim of this study was to investigate the diagnostic potential of these antigens in combination with oral brush biopsies. MATERIAL AND(More)
Treatment of head and neck squamous cell carcinoma (HNSCC) remains challenging. Non‑surgical approaches typically comprise radiotherapy and antineoplastic chemotherapy, of which platinum‑based agents are the most common. Similar to other malignancies, targeted therapies have an increasing role in the treatment of head and neck cancer. The overexpression of(More)
Head and neck squamous cell carcinoma (HNSCC) ranks as the sixth most common tumor entity worldwide. Unfortunately, the multimodal treatment consisting of surgery, radiation, and chemotherapy does not show the desired efficacy. The intent of this study was to evaluate the sensitivity and specificity of an oral brush biopsy in combination with glucose(More)
There is a growing body of evidence indicating that several melanoma-associated antigen-A (MAGE-A) subgroups contribute to the malignancy of head and neck cancer. The present study retrospectively analyzed the expression of all known MAGE-A subgroups in the tumor front and center of 38 head and neck cancer patients (Union for International Cancer Control(More)
Head and neck squamous cell carcinoma (HNSCC) is a heterogeneous disease characterized by a tumor microenvironment (TME) that overexpresses vascular endothelial growth factor receptor (VEGFR) and fibroblast growth factor receptor (FGFR), which can lead to neovascularization, tumor growth and metastasis. Therapeutic strategies inhibiting these signaling(More)
Squamous cell carcinoma of the head and neck (HNSCC) is the sixth most common malignancy worldwide. The past decades have not led to substantial improvement in diagnosis and therapy. Analysis of miRNA-expression may help to determine the progression profiles and outcomes of many different diseases, including HNSCC. Therefore, in this investigation, 43(More)
