|Official Title:||A Phase 1b Pilot Study Evaluating Oral Administration of Freeze-Dried Black Raspberries in Pre-Surgical Patients With Oral Squamous Cell Carcinoma|
- Relationship between the length of short-term LBR administration to human oral cancer patients and the modulation, in oral cavity tissues, of LBR-responsive genes [ Time Frame: up to 60 months ]Statistical summaries of biopsy to surgery changes in quantitative real-time RT-PCR data made on the log scale (geometric mean of percent changes +/- s.e. expressed as a percentage).Confidence intervals produced and significance of the correlation between real-time RT-PCR values and period of treatment (i.e. time from biopsy to surgery) using Fisher's transformation of Spearman's rank correlation tested. Semi-quantitative IHC analyzed using an ordinal logistic model to determine significance of associations between period of treatment and change in staining from biopsy to surgery.
- Evaluate effects of lyophilized freeze-dried black raspberries (LBR) administration in humans on cell proliferation, apoptosis, and angiogenesis in oral cavity tissues using various established biomarkers. [ Time Frame: up to 60 months ]Biomarkers include Ki-67, PCNA, caspase-3, VEGF, or bFGF
- Assess feasibility of administering lyophilized freeze-dried black raspberries in oral troche form to pre-surgical patients diagnosed with squamous cell carcinoma of the oral cavity. [ Time Frame: from 7-28 days ]

lyophilized black raspberries(LBR) administration: 3 LBR troche lozenges (dissolved in mouth), 4 times/day beginning at minimum of 24 hrs following biopsy until night before surgery
I. To determine the relationship between the length of short-term lyophilized black raspberries (LBR) administration to human oral cancer patients and the modulation, in oral cavity tissues, of a subset of specific genes previously identified by us to be "LBR-responsive" and associated with LBR's chemopreventive activity.
I. To evaluate the effects of LBR administration in humans on cell proliferation, apoptosis, and angiogenesis in oral cavity tissues using various established biomarkers including Ki-67 or proliferating cell nuclear antigen (PCNA), caspase-3, vascular endothelial growth factor (VEGF) or basic fibroblast growth factor (bFGF).
II. To assess the feasibility of administering lyophilized freeze-dried black raspberries in oral troche form to pre-surgical patients diagnosed with squamous cell carcinoma of the oral cavity (compliance, tolerance, adverse events).
