title: [High-dose chemotherapy and peripheral hemtopoietic cells (PBPC) in solid tumors].
abstract: High-dose chemotherapy is a policy which is increasing in the field of solid tumors both in Europe and in North America. Hundreds of patients undergo ABMT or PBPCT in Europe every year especially for breast carcinoma. Waiting for the results of several ongoing trials, high-dose chemotherapy has shown to be of extreme interest in the adjuvant setting of patients with high risk breast cancer in phase II trials. The best results had been reported by Peters and Gianni; with a minimum follow-up of 5 years 65 and 56% of their patients with ten or more axillary lymph nodes are alive disease free. These results are better than any others with standard doses. The only one published trial (from South Africa) on advanced disease clearly favours high-doses of cyclophosphamide, mitoxantrone and etoposide versus standard doses of cyclophosphamide, mitoxantrone and vincristine in terms of overall survival and time to relapse. The use of PBPC replacing ABMT has allowed an easier tolerability of the procedure and a reduction of the costs. There is a clear reduction of the toxic death rate to 1% in 1995 for breast cancer patients compared with 20% of fifteen years ago. Germ cell tumors in responding relapse after salvage chemotherapy seem to be ideal candidates for ABMT/PBPC programs with an expected 40% disease free survival. The clinical impact of the PBPC contamination by tumor cells is still nowadays a matter of debate at least for breast carcinoma and neuroblastoma. This review will focus on the present situation of high-dose chemotherapy for solid tumors with some insights to new technologies and their applications.
