Abstract
This article has been retracted: please see Elsevier Policy on Article Withdrawal(http://www.elsevier.com/locate/withdrawalpolicy).
This article has been retracted at the request of the Authors.
Retraction due to duplication of data publication and text re-cycling by the authors: The Proceedings article has been retracted at the request of the authors as most of the data presented and text had already appeared in the author's previous paper entitled "A randomized attempt to increase the efficacy of cytotoxic chemotherapy in metastatic breast cancer by hormonal synchronization". M E Lippman, J Cassidy, M Wesley and R C Young,J Clin Oncol, 2(1984) 28–36.This was due to their misunderstanding of the respective publishing and copyright policies of the journals and the implications of publishing in a conference proceedings.
