Abstract

In advanced breast cancer high-dose consolidation chemotherapy with haematological rescue has resulted in prolonged disease free and overall survival in a small percentage of patients. Maximal reduction of the tumor burden by intensive induction treatment preceding the high-dose chemotherapy may favor that outcome. The aims of this study were to find a rapid highly effective induction regimen with acceptable toxicity and to examine the optimal time for peripheral blood progenitor cell (PBPC) collection for haematological rescue. Twenty-four patients received 4 cycles of FAC chemotherapy (5-FU, adriamycin, cyclosphamide), each followed by 10 micrograms/kg/d of lenograstim (glycosylated rHuG-CSF) s.c. day 2 to 11. Chemotherapy was administered at 4 dose intensity levels with 6 patients including at each level (level 1: 500(F)/50(A)/500(C) mg/m2/3wk, level 2: 500/50/500 mg/m2/2wk, level 3: 500/75/500 mg/m2/2wk, m2/2wk, level 4: 500/75/1000 mg/m2/2wk d1 i.v.). In addition lenograstim (10 micrograms/kg/d s.c.) was administered for a period of 10 days before (period X) and after (period Y) chemotherapy. In 16 patients (4 at each dose intensity level) assessment of PBPC was performed during period X and Y as well as during cycle 1 and...Continue Reading

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.
