Brief summary
Therapies involving the immune system have already shown great promise in early clinical trials for the treatment of renal cell carcinoma and melanoma. One of the great challenges now facing this field is to extend these findings to other cancers. Little is currently understood about the nature of the immune response to more common gastrointestinal cancers. The first goal of this proposal is to collect blood and tissue samples from patients with early or late stage gastrointestinal cancers. These samples will be evaluated to better understand the immune response to these two cancers. The second goal of this proposal is to evaluate the specimens of these patients for changes and genetic markers that correlate with the presence of cancer. The information gathered from these studies will directly enhance our ability to design, conduct and monitor novel immunotherapeutic protocols for the treatment of patients with gastrointestinal cancer.
Detailed description
The first goal of this proposal is to collect cells from the peripheral blood, tumor draining lymph nodes and tumor infiltrating lymphocytes in patients with early or late stage gastrointestinal cancers. These samples will be evaluated in a variety of immunological assays to better understand the immune response to these two cancers. The second goal of this proposal is to evaluate using novel proteomic, cellomic, and genomic techniques the serum and peripheral blood lymphocytes of these patients for protein, cellular changes and genetic markers that correlate with the presence of cancer. The information gathered from these studies will directly enhance our ability to design, conduct and monitor novel immunotherapeutic protocols for the treatment of patients with gastrointestinal cancer.
Interventions
OTHERSpecimen bank
Patients will be asked to provide approximately 60-120 cc (4-8 tablespoons) of peripheral blood. Select patients who undergo surgical resection of their tumor will be asked to provide portions of the tumor and tumor draining lymph nodes for further analysis. In addition patients undergoing surgical resection may be asked to provide additional peripheral blood samples at time of routine follow-up (at least 4-6 weeks after initial blood draw and between subsequent draws).
