Evolving incidence patterns for locally advanced operable breast cancer by receptor status: SEER 2010-2021.

ABSTRACT: Tumor biologic risk has replaced anatomic disease burden for guiding chemotherapy use in HR-positive, early-stage breast cancer. Recent surgical trials support less frequent axillary lymph node dissection, potentially impacting incidence of N2-3 diagnoses. As the field considers applying genomic risk assessment tools for locally advanced, operable HR-positive breast cancer, we estimated current incidence of these cancers, focusing on HR-positive/HER2-negative disease. Of 486,031 cases recorded with Stage I-III HR-positive/HER2-negative disease in the U.S. National Cancer Institute Surveillance, Epidemiology, and End Results-17 database (2010-2021), 28,585 (5.9%) and 23,307 (4.8%) had N2-3M0(Any T) and T3-4N0-1M0 disease, respectively. Invasive lobular cancer, observed across all disease st
