New Q-Probes on expression rates in invasive breast cancer

Laboratories participating in the Q-Probes will provide their 2018 annual data on the percent of cases positive for ER, PR, and HER2. Laboratories will also provide data on up to 50 current cases as they accrue so that expression rates can be stratified by histologic type and grade and patient age. Unlike other CAP Surveys, this study allows laboratories to compare their results on patient specimens with those of other laboratories.

Participating laboratories will be asked to complete an accompanying questionnaire that will make it possible for them to also benchmark predictive marker reporting practices, with emphasis on the ways in which laboratories comply with the ASCO/CAP guideline for ER, PR, and HER2.

To enroll or for more information about Q-Probes No. 193, call the CAP at 800-323-4040 option 1. Or order online at https://estore.cap.org/, Quality Management.
