CHICAGO -- Follow-up to a National Cancer Institute trial indicates a modified radical mastectomy is no better for women with phase I or II cancer than breast-conserving surgery

These results echo the recently released findings of a 20-year follow-up of women who took part in two clinical trials comparing mastectomy with breast-conserving surgery in the 1970s and 1980s. Both trials failed to observe a survival advantage to mastectomy after 20 years among 1,851 patients in the United States and 701 patients in Italy Dr. Matthew Poggi at the annual meeting of the Radiological Society of North America.

Dr. Poggi said the biggest distinction between the current NCI trial and the other trials is the NCI trial did not require negative rumor margins. He could not say how many women had positive margins as some surgeries were performed at other institutions, but he estimated it at roughly 20%.

The NCI trial was conducted between 1979 and 1987. A total of 116 women were randomized to modified radical mastectomy and 121 to lumpectomy plus radiation. Radiation therapy was 4,500-5,040 cGy in 180 cGy administered five times a week for 5-5.5 weeks. All were given one boost, but no chest wall radiation was given, Dr. ...
