Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This pilot phase I trial studies freeze-dried black raspberries in treating patients with oral squamous cell cancer undergoing surgery. Chemoprevention is the use of certain drugs to keep cancer from forming. Eating freeze-dried black raspberries may help prevent or treat oral cancer

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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).

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Patients with newly diagnosed, biopsy-proven previously untreated squamous cell carcinoma (SCC) of the oral cavity (stages I - IV); suspected cases of SCC will be allowed if biopsy is performed and results of SCC confirmed on subsequent histopathologic analysis (i.e. frozen section) prior to enrollment and initiation of LBR administration
* Patients must already be planned for surgical resection of their tumor (prior to being considered eligible for this study)
* Patients must be able to take nutrition/medications orally
* No prior history of intolerance or allergy to berry or berry-containing products

Exclusion Criteria

* History of intolerance (including hypersensitivity or allergy) to berry or berry-containing products
* Known history of bleeding disorder or patient on systemic anticoagulation therapy (i.e. coumadin, heparin) for purposes of the study biopsy
* Pregnant women; although there are no known adverse effects of black raspberries upon the fetus, if patients become pregnant during period of LBR administration, then LBR will be discontinued and patient will be removed from the study
* Inability to grant informed consent
* Patients must not be planning to receive chemotherapy or radiation therapy prior to their surgery or this will affect endpoint analysis and these patients will be excluded from the study
* Patients taking cyclooxygenase (COX)-I or COX-2 inhibitors, who cannot be taken off the medication due to their clinical condition will be excluded given that these agents may interfere with biomarkers studied
* Vegetarians will be excluded from the study since we anticipate that this patient population will have difficulty adhering to a low-phenolic diet (restricts basically all plant-based foods)
