Among all sorts of news circulating as a result of the recent breast cancer conference in San Antonio, Texas is a report about an international study that has many touting Canadian chemotherapy treatments as the best therapies around -- even better than the commonly-used AC/T cocktail (doxorubicin and cyclophosphamide followed by paclitaxel) . The winning Canadian drug combinations -- EC/T (epirubicin and cyclophosphamide followed by paclitaxel) and CEF (cyclophosphamide, epirubicin, and fluorouracil) -- are reportedly more effective at preventing breast cancer recurrence than AC/T.
About 2,104 women in Canada and the United States participated in this international study. All had undergone surgery to remove a tumor and were receiving chemotherapy. The women, aged 60 and under, all had cancer that had spread to their lymph nodes, indicating the disease was likely to spread.
The women received one of three treatments -- AC/T, EC/T, or CEF -- and results revealed that for every 100 women who received EC/T or CEF, 10 women would suffer a recurrence. For every 100 women who received AC/T, 15 women would relapse.
The lead researcher of the study says it's too soon to say whether EC/T and CEF are more effective in the long-term. So participants will be followed for some time while researchers will try to make sense of their initial findings. In the meantime, they suspect AC/T will continue to be widely used because of its lesser side effects.
