A Phase 1b Pilot Study Evaluating Oral Administration of Freeze-Dried Black Raspberries in Pre-Surgical Patients With Oral Squamous Cell Carcinoma
PRIMARY OBJECTIVES:
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.
SECONDARY OBJECTIVES:
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).

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
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.
