$13 million grant to fund research into molecular targets for colorectal cancer

Grant and Award Announcement

Vanderbilt University Medical Center

NASHVILLE, Tenn. (April 16, 2002) – A team of Vanderbilt investigators has been awarded a highly competitive, $13 million Specialized Program of Research Excellence (SPORE) grant to fund an interdisciplinary program focused on colorectal cancer, the second leading cancer killer.

The National Cancer Institute SPORE in GI Cancer grant is the second SPORE to be funded at the Vanderbilt-Ingram Cancer Center, which received a SPORE in Lung Cancer last year. The GI SPORE involves the Gastroenterology Programs in the departments of Medicine, Surgery, Cancer Biology and Radiation Oncology.

The National Cancer Institute established SPOREs ten years ago to promote interdisciplinary research into specific cancer types that focuses on projects with a "translational" emphasis; that is, work that spans the gap from basic laboratory discovery to clinical application. Nationwide, 33 SPOREs for breast, GI, genitourinary, lung, ovarian, prostate and skin cancers are active at 23 institutions. Vanderbilt-Ingram, which received a SPORE in Lung Cancer last year, now joins only six other cancer centers to have more than one active SPORE grant. "We’re very excited about our SPORE in GI Cancer," said Dr. Robert J. Coffey Jr., Ingram Professor of Cancer Research, professor of Medicine and Cell and Developmental Biology, and director of the new SPORE. "Up till now, there have only been two SPOREs in GI cancers, none of which have focused exclusively on colorectal cancer."

Nearly 150,000 cases of colorectal cancer are expected to be diagnosed this year, according to the American Cancer Society, and because risk increases after age 50, incidence is expected to climb in coming years as the Baby Boom generation ages. More than 46,000 deaths are expected from colorectal cancer, making it the second leading cancer killer in both men and women.

The GI SPORE will provide $2.75 million each year for five years beginning June 1. The funding will support five research projects, which focus on translational research using a variety of molecular targets for prevention and therapy of colorectal cancer. The funding also supports six shared resources (cores).

Projects and their leaders are: Project 1 will focus on the epidermal growth factor receptor as a target for therapy in colorectal cancer (Coffey and Dr. Mace Rothenberg). This project will include a clinical trial using Iressa, an investigational EGF receptor-blocking agent.

Project 2 will evaluate combinations of drugs to block both the EGF receptor and cyclooxygenase 2 (COX-2) in Phase I and II trials in colorectal cancer patients (Coffey and Dr. Jordan Berlin).

Project 3 will use DNA microarray and imaging mass spectrometry to identify markers that correspond to response to neoadjuvant chemotherapy and radiation. The ultimate goal is to be able to predict response and tailor therapy for an individual patient. (Dr. Daniel Beauchamp and Dr. Bapsi Chak).

Project 4 will examine the role of p120 – a protein first identified at Vanderbilt – in the spread of colorectal cancer. (Al Reynolds, Ph.D., and Dr. Scott Pearson) Project 5 aims to identify markers for the recurrence of colon polyps that ultimately could be used to determine which patients might benefit most from regular screenings and preventive agents and which might reasonably undergo screening at longer intervals. (Wei Zheng, M.D., Ph.D., and Dr. William Grady).

Cores and their leaders are Administrative, Coffey; Tissue, Kay Washington, M.D., Ph.D.; Clinical Trials, Rothenberg; Emerging Technologies, Richard Caprioli, Ph.D., and Shawn Levy, Ph.D.; Biostatistics, Yu Shyr, Ph.D.; and Biomedical Informatics, Mary Edgerton, M.D., Ph.D. The cores were judged to be very strong, according to the reviewers, especially the Biostatistics Core, which they called a "model" for future projects.

The Vanderbilt-Ingram Cancer Center is the only Comprehensive Cancer Center designated by the National Cancer Institute in Tennessee, and one of only 41 nationwide. This designation, the highest ranking awarded to cancer centers by the world’s foremost authority on cancer, recognizes research excellence in cancer causes, development, treatment and prevention, as well as a demonstrated commitment to community education, information and outreach.
