Patient management strategies and transplantation techniques in european stem cell transplantation centers offering breast cancer patients high-dose chemotherapy with peripheral blood stem cell support: a joint report from the EORTC and EBMT.

BACKGROUND AND OBJECTIVES It is increasingly being realized that there are very considerable variations in individual hospitals' strategies for managing a particular group of patients, even if using similar therapeutic regimens. Such variations make it impossible to generalize estimations of treatment costs from one setting to others. The objective of this study is to examine the extent of variation in the current approaches in Europe to peripheral blood stem cell transplantation (PBSCT) in breast carcinoma. DESIGN AND METHODS A questionnaire was developed and sent to the EBMT member institutions. The questionnaire comprised 85 questions covering the technical and clinical issues involved and the strategies followed for the management of the patients. This paper reports the results of the survey primarily by means of descriptive, univariate frequency distributions. The results of a more analytical approach, aiming at explaining patterns in the variations observed are also presented. RESULTS A completed questionnaire was returned by 162 centers; 60% university hospitals, 14% cancer centers and the rest general hospitals. Considerable variations are observed between the centers with respect to all aspects of patient management and technical procedures investigated. In many respects, general hospitals follow different routines from university hospitals and dedicated cancer centers. INTERPRETATION AND CONCLUSIONS Variability to the extent observed indicates an important scope for optimization of the procedures and a large potential for reduction of costs and perhaps for improvement of outcomes. Economic evaluations, for instance comparing PBSCT with autologous BMT as support for high dose chemotherapy, can not be generalized from one setting to another without careful examination of the procedures and strategies followed in each setting. European hospitals treating breast cancer patients with high dose chemotherapy supported by transplantation of peripheral blood stem cells use very different technical procedures for mobilization, harvest and re-implantation of stem cells. In addition, there are also wide variations in the way they manage the patients, e.g. with regard to the criteria for discharge from hospital after re-implantation.
