  Purpose

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.

Primary Outcome Measures:
  • Determine if preoperative (300 mg/day x 21 days) soy isoflavone modulates p16 methylation and expression of p16, COX-2, VEGF, EGFR, IL6, p53 and Bcl-xL in tumor/non-tumor mucosa in patients with head/neck squamous carcinoma undergoing tumor resection. [ Time Frame: 6 months, 12 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • toxicity of short-term, preoperative treatment with soy isoflavone. [ Time Frame: 12 months ] [ Designated as safety issue: Yes ]
  • overall and relapse-free survival. [ Time Frame: 12 months ] [ Designated as safety issue: No ]

Estimated Enrollment: 120
Study Start Date: February 2010
Estimated Study Completion Date: December 2016
Estimated Primary Completion Date: December 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Soy isoflavone treatment arm
A three week administration of moderate (300 mg daily) dose soy isoflavone
Drug: Soy Isoflavone
Dosage - 300 mg/day Route of Administration - oral Frequency - 2, 150 mg capsules daily with food for 21 doses
Other Name: PTI G-2535 (unconjugated isoflavones - 70)

Detailed Description:

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.
