Long‐term followup of breast cancer patients: The 30‐year report

Abstract

A cohort of 1458 breast cancer patients treated by radical mastectomy in the years 1940–1943 has been followed since that time. There are 184 known alive an average of 30.6 years later. Of the others, 836 have died of either their first or second breast cancers, and 349 have died of other causes. Sixty‐nine seem to have been definitely lost to followup, while followup is active but incomplete for 30 others. The actuarial 30‐year survival rate is 38%, and the cumulative rate of clinical second primary breast cancers is 16.4%. Copyright © 1974 American Cancer Society
