Guidelines can address specific clinical situations (disease-oriented) or use of approved medical products, procedures, or tests (modality-oriented). Using the best available evidence, ASCO expert panels identify and develop practice recommendations for specific areas of cancer care that would benefit from using practice guidelines. Learn more about ASCO's Guideline Development Process.

In addition, the Practice Guidelines Implementation Network (PGIN) is a working group focused on the dissemination and implementation of ASCO guidelines. PGIN member activities include serving on Guideline Expert Panels; reviewing Guidelines; promoting dissemination of Guidelines and Clinical Tools; and reviewing and pilot testing selected Clinical Tools. PGIN members participate in these activities with the goal of assisting practices to increase the quality of oncology care, including facilitating shared decision-making with people with cancer and their caregivers. Members include oncologists, primarily community-based, oncology nurses, hematology/oncology pharmacists, and oncology practice managers.
