Description

Rouzier et al developed a nomogram for predicting the probability of being free from distant metastases 5 or 10 years after preoperative anthracycline chemotherapy and surgery for breast cancer. This can help advise patients about outcome following this form of management. The authors are from University of Texas Houston M.D. Anderson Cancer Center, Institut Gustave Roussy in Villejuif, and Hotel-Dieu in Beirut.
