We hypothesize that p16 hypermethylation in tumor and adjacent non-tumor mucosa identifies patients who have impaired response to stress signals associated with smoking, and that p16 hypermethylation and associated over expression of downstream targets such as COX-2, VEGF, EGFR and IL6 can be abrogated by soy isoflavone supplementation.
The overall long term goal of the proposed research is to determine if administration of a soy isoflavone will provide a basis for secondary prevention and cancer control that can decrease tumor recurrence and increase overall survival and quality of life in patients with head and neck squamous carcinoma. Secondarily, we hope to identify candidate genes and intermediate endpoints for future primary prevention trials. The inclusion of Karmanos Cancer Institute and Emory University will provide additional new patient accrual and improved access to minority patients.
We will conduct a Phase II trial to determine whether short term (3 weeks) soy isoflavone administration can modulate p16 methylation and tissue expression of p53, p16, EGFR, VEGF, Bcl-xL and COX-2 in resected specimens and adjacent non-tumor mucosa to potentially identify markers useful as intermediate endpoints and define how quickly changes in gene markers might be seen. Correlation of pretreatment tissue markers with serum and saliva markers will be determined to identify potential surrogates of tissue markers that could be useful in serial monitoring protocols in patients or high risk populations with oral leukoplakia or dysplasia where serial tumor specimens are not available. This protocol is designed to provide a comprehensive assessment of adjuvant soy isoflavone and molecular markers in a prospective clinical trial setting. Accrual will be enhanced by the addition of Karmanos Cancer Institute and Emory University.

Correlation Between Squamous Cell Carcinoma Antigen Level and the Clinicopathological Features of Early-Stage Cervical Squamous Cell Carcinoma and the Predictive Value of Squamous Cell Carcinoma Antigen Combined With Computed Tomography Scan for Lymph Node Metastasis.
The aim of this study was to analyze the relationship between serum squamous cell carcinoma antigen (SCC-Ag) and the clinicopathological features of cervical squamous cell carcinoma. The value of SCC-...

This study aimed to construct a prediction model for cervical squamous cell carcinoma and evaluate its accuracy in diagnosing cervical squamous cell carcinoma.
Overexpression of keratin 17 (K17) is highly associated with poor prognosis in squamous cell carcinoma (SCC) of the cervix. This study was performed to (1) determine whether K17 may be a prognostic bi...
A carcinoma derived from stratified squamous epithelium. It may also occur in sites where glandular or columnar epithelium is normally present. (From Stedman, 25th ed)
A mixed adenocarcinoma and squamous cell or epidermoid carcinoma.
A skin carcinoma that histologically exhibits both basal and squamous elements. (From Dorland, 27th ed)
A heterogeneous aggregate of at least three distinct histological types of lung cancer, including SQUAMOUS CELL CARCINOMA; ADENOCARCINOMA; and LARGE CELL CARCINOMA. They are dealt with collectively because of their shared treatment strategy.
Cancer or tumors of the URETHRA. Benign epithelial tumors of the urethra usually consist of squamous and transitional cells. Primary urethral carcinomas are rare and typically of squamous cells. Urethral carcinoma is the only urological malignancy that is more common in females than in males.
Stress is caused by your perception of situations around you and then the reaction of your body to them. The automatic stress response to unexpected events is known as 'fight or flight'. Discovered by Walter Cannon in 1932, it is the release of h...
