Abstract:received P+AI (94.2% 1st line; 5.8% ≥2 nd line) and 741 pts received P+F (51.1% 1 st line; 48.9% ≥2 nd line). Mean (SD) age at palbociclib initiation was 62.3 (10.6) years for P+AI and 64.0 (10.0) years for P+F pts. Most pts had a performance status (ECOG) at palbociclib initiation of 0 or 1 (P+AI: 86.4%; P+F: 87.7%). Of those pts with metastatic disease (P+AI: n = 906; P+F: n = 661), 49.2% P+AI and 48.7% P+F pts had visceral disease; 43.5% P+AI and 39.5% P+F pts had bone only metastases.Median follow-up durat… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
