Fluorouracil and dose-dense chemotherapy in adjuvant treatment of patients with early-stage breast cancer: an open-label, 2 × 2 factorial, randomised phase 3 trial. Lancet 2015; 385:1863–1872.

Conclusion

Some 2091 women with operable node positive breast cancer were enrolled. Dose-dense chemotherapy (every 2 weeks, instead of every 3 weeks) improved overall survival after median follow-up of seven years: 94 versus 89 per cent; P=0.001. Survival was unaffected by addition of fluorouracil to standard chemotherapy.
