History of NCCN

On January 31, 1995, a press conference was held to announce the creation of a national alliance to develop and institute standards of care for the treatment of cancer and perform outcomes research – and so the NCCN was born. With 13 original NCCN Member Institutions, the goal was to ensure delivery of high-quality, cost-effective services to people with cancer across the country. NCCN became a developer and promoter of national programs to facilitate the fulfillment of NCCN Member Institution missions in education, research, and patient care. Now an alliance of 30 of the leading cancer centers, NCCN develops and communicates scientific, evaluative information to better inform the decision-making process between patients and physicians, ultimately improving patient outcomes.

What we do


The core resources made available by NCCN are the NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines®). These guidelines are the recognized standard for clinical policy in oncology and are the most comprehensive and most frequently updated clinical practice guidelines available in any area of medicine. Covering 97 percent of all patients with cancer and updated on a continual basis, the NCCN Guidelines® are developed through and explicit review of evidence (clinical trials, existing treatment protocol, etc.) integrated with expert medical judgment and recommendations by panels that are made up of representatives from the 30 NCCN Member Institutions.

The panels, each with a particular focus—tumor type, prevention, detection, risk reduction, or supportive care—comprise physicians and oncology researchers from the NCCN Member Institutions.

How we help patients


NCCN aims to provide people with cancer and the general public with state-of-the-art cancer treatment information in easy-to-understand language. The NCCN Guidelines for Patients®, translations of the NCCN clinical guidelines, help patients with cancer talk with their physicians about the best treatment options for their disease. NCCN Guidelines for Patients® do not replace the expertise and clinical judgment of the physician.

NCCN is committed to developing a comprehensive library with support from the NCCN Foundation®.
