NCG 5. Numerous studies have strongly suggested its association with higher recurrence risk in early-stage breast cancer and, to a lesser extent, increased resistance to hormonal therapy perhaps more so with tamoxifen than with aromatase inhibitors , resistance to nonanthracycline therapy, enhanced sensitivity to doxorubicin, and, in some series, to taxane-based therapy [ 14 ].
