1Reported efficacy for DBCG 77B is based on the 2010 update.
2Reported efficacy for NSABP B-13 is based on the 1996 update.
Note: No further systemic treatment; many of these trials incorporated RT, however (see individual papers for details). Jakesz et al. 1998 was conducted prior to routine testing of HER2, so it technically included "double-negative" patients. ECOG E1180 is also known as INT-0011.
