Breast Cancer Trials of the Ludwig and International Breast Cancer Study Group
In early 1977 a meeting was convened by the Ludwig Institute for Cancer Research in Switzerland to plan international participation in adjuvant breast cancer trials. The group of international participants have now completed an initial series of four trials (studies I–IV) from July 1, 1978, to August 31, 1981 [1–7]. A fifth trial (study V) involving perioperative therapy completed accrual of 2,517 patients in December 1985 and will be analyzed initially in late 1986. The initial participants group conducting the trials, the Ludwig Breast Cancer Study Group, has now been renamed the International Breast Cancer Study Group (IBCSG), and this group has planned two new adjuvant protocols for commencement during 1986 (studies VI and VII).
