Approximately 90% of patients receiving highly emetogenic chemotherapy for treatment of cancer experience nausea and vomiting, making it one of the most prominent and feared side effects of cancer treatment. Not only does nausea and vomiting affect quality of life for patients, which can lead to poor compliance to chemotherapy or radiation therapy, but it can have serious effects on a patient's overall health, including severe metabolic imbalances and dehydration. There are, however, a number of prophylactic treatments for nausea and vomiting available to patients, which lower the incidence of nausea and vomiting to 30%.[i] "At NCCN, our mission is to improve the lives of patients with cancer, and we are excited to be able to provide the information that will help patients better understand this common side effect of cancer treatment," said Marcie R. Reeder, MPH, Executive Director, NCCN Foundation. "The NCCN Guidelines for Patients for Nausea and Vomiting are the first of a highly anticipated library of supportive care resources that provide patients with the same information their doctors use." The patient resources for nausea and vomiting are available on NCCN.org, as well as on the new NCCN Patient Guides for Cancer mobile app, which launched earlier this month. The new app is available free of charge for Android and iOS devices and features the complete library of NCCN Guidelines for Patients and NCCN Quick Guide™ sheets. "With the launch of the new mobile app, patients and caregivers have easy-to-understand cancer treatment information at the tips of their fingers. We are excited to deliver this world-class information to all audiences, whether in print, online, or via mobile device," added Ms. Reeder.
