 * From NSABP B-06, B-13, B-14, B-19, and B-20. N=1259 (1024, ER+; 235, ER-). Treatments were randomized according to the trial.
 * ER(-): Overall 8-yr RFS 81% vs 90%(+Chemo). Survival 93% vs 91% (NS).
 * ER(+): RFS 86% vs 93%(+Tam) vs 95% (+Tam+Chemo). Survival 90% vs 92% vs 97%.
 * Overall mortality 8% (one-half of all deaths were attributed to breast cancer)
 * Conclusion: Adjuvant therapy should be considered in this population
