Study of CIPN risk in Early-stage Breast Cancer

This research study is studying proteins in the blood of patients with early-stage breast cancer. We want to see if these proteins can predict the occurrence of damage to the ends of nerves in hands and feet, which is a side-effect called chemotherapy induced peripheral neuropathy (CIPN). There is currently no test to check risk of CIPN. Researchers hope to use the results of this study to create a new test that would identify patients at increased risk of CIPN and help doctors select the best treatment and post-treatment care for their patients and improve patient recovery after chemotherapy.
