PURPOSE As an approach to evaluate the expression pattern and status of activation of signaling pathways in clinical specimens from head and neck squamous cell carcinoma (HNSCC) patients, we established the Head and Neck Cancer Tissue Array Initiative, an international consortium aimed at developing a high-density HNSCC tissue microarray, with a high(More)
Using expression microarray, we have previously shown that human cyclin G2 (hCG2) is significantly down-regulated in laser capture microdissected oral cancer epithelia. Western analysis showed detectable hCG2 protein in normal (2 of 2) but not in malignant (4 of 4) oral keratinocyte cell lines. Immunohistochemistry analysis done on oral cancers showed that(More)
Alteration in epidermal growth factor receptor (EGFR) expression is frequently associated with malignant transformation of epithelial tissues, including oral mucosa. This study examines the mutations in the coding region of the human EGFR gene in normal and malignant human oral keratinocytes. To examine the intragenic mutations in the human EGFR gene, a(More)
For the doctors and other medical staff treating oral cancers, it is necessary to standardize basic concepts and rules on oral cancers to progress in the treatment, research and diagnosis. Oral cancers are integrated in head and neck cancers and are applied to the general rules on head and neck cancer, but it is considered that more detailed rules based on(More)
PURPOSE Long-term outcomes of patients with squamous cell carcinoma of the head and neck (SCCHN) remain unsatisfactory despite advances in combination of treatment modalities. SCCHN is characterized by locoregional spread and it is clinically accessible, making it an attractive target for intratumoral biological therapies. EXPERIMENTAL DESIGN OBP-301 is a(More)
BACKGROUND Osteoporosis (OP) is one of the most serious diseases in the modern world, and OP patients frequently suffer from fragility fractures in the hip, spine and wrist, resulting in a limited quality of life. Although bisphosphonates (BPs) are the most effective class of anti-bone-resorptive drugs currently available and the most commonly prescribed(More)
Tumor protein D54 (TPD54) belongs to the TPD52 family of proteins and is expressed in several types of cancer, including oral squamous cell carcinoma (OSCC). Here, we investigated relationships between various OSCC-related characteristics and TPD54 expression in vitro. The expression of TPD54 in several OSCC-derived cell lines and normal, non-malignant,(More)
PURPOSE We evaluated whether preoperative chemotherapy with S-1 and concurrent radiotherapy is feasible and efficacious in the treatment of advanced oral squamous cell carcinoma. METHODS Participants comprised 39 patients with oral carcinoma (stage III, n = 15; stage IVA, n = 24). All patients received a total radiation dose of 40 Gy, in once-daily 2-Gy(More)
Squamous cell carcinoma (SCC) is one of the most common cancers of the head and neck region worldwide and is generally treated surgically in combination with radiotherapy and/or chemotherapy. However, anticancer agents have numerous serious side effects, and alternative, less toxic agents that are effective as chemotherapeutics for SCC are required. The(More)
PURPOSE The aims of this study were to use computed tomography (CT) imaging to determine the anatomical features of the mandibular body and ramus in Japanese subjects and to relate the findings to bone harvesting from the mandibular ramus. MATERIALS AND METHODS The mandibles of 100 patients (28 males and 72 females) under dental implant treatment plan(More)
