Their project—the final one to be funded in the 17-year history of the Better Than Ever Training Program—is entitled: “Evaluating the Role of Diffusion Tensor Imaging in Predicting Development of Chemotherapy Induced Peripheral Neuropathy (CIPN) in Patients with Breast Cancer.”
In a description of their work, they note that some chemotherapies cause nerve damage that induces peripheral neuropathy, which can be debilitating and affect a patient’s daily activities long after their cancer treatment is completed. Symptoms can be both sensory and motor like pain, numbness, weakness, cramps, balance issues or problems walking. Sometimes these symptoms can present early on during the course of chemotherapy and the treatment can be altered (such as reduced dosage or treatment stoppage). While this may stop symptoms and help a few patients, such interventions might not be helpful in others. It is critical to identify those at risk of developing peripheral neuropathy so that appropriate interventions can be taken early on and prevent onset of such long-lasting side effects. Currently, assessment of peripheral neuropathy relies on clinical examination and sometimes, electrophysiologic testing is used.
Magnetic Resonance Neurography (MRN) and diffusion tensor imaging (DTI) are new techniques which are increasingly being used to evaluate peripheral nerves and assess peripheral neuropathy. These techniques rely heavily on certain imaging sequencing obtained by MRI. The investigators propose to further explore these novel imaging methods to see if they can help identify those at risk of developing CIPN.
In this study, they will enroll patients with breast cancer who will be treated with chemotherapy. Patients will undergo imaging of their legs and ankles before and after chemotherapy. We will investigate a possible relationship between these techniques and CIPN as a potential indicator to identify those at risk of developing neuropathy and as an aid in developing and evaluating preventive strategies in patients who need to undergo chemotherapy.
The Better Than Ever training program, the brainchild of program founder and champion Heather Alberts, wife of recently retired UA Cancer Center director emeritus David Alberts, MD, was a fitness training and fundraising program designed to help make walking, running or biking a regular part life.
From its inception in 2000, the program raised funds to support both basic science research and investigator-initiated clinical trials with an emphasis on breast and gynecologic cancers under the umbrella of Women’s Cancers at the UA Cancer Center.
“Sadly, the fundraising arm of the Better Than Ever program has come to an end and we released our final request for applications earlier this year. The focus of this year’s RFA was on correlative studies from ongoing or completed investigator-initiated clinical trials for women’s cancers,” said Setsuko K. Chamber, MD (right), chair of the BTE Scientific Review Committee, which selects recipients for these grants.
“This has been an extremely successful UA Cancer Center outreach effort and we are pleased that this year’s award brings the 17-year grant distribution total to just under $2 million. What an impressive end to this wonderful program!” she added.
