Among women with receptor-positive disease, the effects of five years of tamoxifen were really pretty impressive. It was preventing about 40 percent of the recurrences that you’d see within the first 10 years. And these differences are durable, they persist, we’ve now got 15-year follow-up on these trials. And those differences in the risk of recurrence, the differences in survival, are at least as big at year 15, as they were at year five or year 10. So, these are durable differences.

For chemotherapy, we don’t have the results from the new trials of taxanes, but what we do have is the long-term outcome in the old trials, the CMF chemotherapy or anthrocycline-based chemotherapy. And we see small, but real differences in long-term survival from CMF chemotherapy. We see the anthrocycline-based chemotherapy being a little bit better than the CMF chemotherapy in terms of long-term outcome. They’re small differences, but they’re real, because the numbers randomized were so big.
