A joint letter to the editor in the Journal of Clinical Oncology provides an important reminder of the intent of the ASCO and College of American Pathologists (CAP) guideline panel on Human Epidermal Growth Factor Receptor 2 (HER2) Testing, and also reconciles some pathology technical aspects with the recent guideline on Immunohistochemical Testing of Estrogen and Progesterone Receptor (ER and PgR) Testing in breast cancer. Read the letter by Elizabeth Hammond, MD, Daniel F. Hayes, MD and Antonio Wolff, MD, co-chairs of the ASCO/CAP guideline panels.

CAP Accreditation Program requirements for ER/PgR testing are being created and will be available in the June 2010 edition of the Anatomic Pathology (ANP) Accreditation Checklist. These new requirements will assure the quality of ER/PgR testing provided by accredited laboratories and incorporate CAP/ASCO ER/PgR guideline recommendations into the CAP accreditation program.
CAP accredited laboratories performing ER/PgR testing will be required to enroll and participate in CAP-accepted proficiency testing by 2011.
Learn more about new and revised checklist requirements.
With CAP Surveys, you can prepare to meet the PT requirements as outlined in the newly adopted CAP/ASCO ER/PgR guideline and the upcoming CAP accreditation checklist requirements.
