We analysed the outcomes of women with metastatic breast cancer (MBC) from three randomised phase III trials of aromatase inhibitors according to oestrogen receptor (ER) and progesterone receptor (PgR) status. Both receptors were analysed in 1010 of the 1870 women (54%), including 31 that were ER-/PgR-, which were excluded. Of the remaining 979, 726 (74%) were ER+/PgR+ but 253 were single hormone receptor positive (213 ER+/PgR-, 40 ER-/PgR+). Although there were no differences in clinical benefit or time to progression, the median overall survival of women with ER+/PgR+ tumours was significantly longer than those with single HR positive tumours (800 versus 600 days, p=0.01). In women with ER+ tumours, the median overall survival of those with tumours that were also PgR+ was significantly longer than those that were PgR- (800 versus 625 days, p=0.02). The PgR status is an important prognostic factor for survival in MBC.
Survival increased significantly in women with advanced ovarian cancer after centralized primary treatment. • Disease-free survival increased significantly in women with advanced ovarian cancer after centralization. • Centralization was identified as a significant independent factor for increased disease-free and relative survival. • Complete cytoreduction was identified as a significant independent factor for increased disease-free and relative survival.
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.
