The objective of this study was to assess the toxicity and efficacy of high-dose chemotherapy (HDC) with autologous peripheral stem cell transplantation (APBSCT) in women with metastatic or high risk ($\geq$9 axillary nodal involvement) stage II-III breast cancer. Forty-five women with either metastatic (n=23) or high risk (n=22) breast cancer were enrolled in the study and treated with HDC followed by APBSCT. At the time of transplant, the median age was 39 years (range: 26-64). All patients were pretreated with standard chemotherapy regimens. Metastatic patients with progression or stable disease after first-line chemotherapy were excluded. PBSC were harvested using G-CSF and the conditioning regimens ICE (ifosfamide, carboplatin, etoposide) and CNV (cyclophosphamide, mitoxantrone, etoposide) were used in most of the patients. The median number of CD34+ cells infused was 5.40x$10^6$/kg (range: 1.82-19.87x$10^6$ kg). G-CSF or GM-CSF was used in 39 patients in the post-transplant period. The median leukocyte engraftment (leukocyte<1000/$mm^3$) was 11 days (0-24) and platelet engraftment (20000/$mm^3$) was 11 days (0-27). In the early transplant period (0-$30^th$ day), 4 (8.8%) out of 45 patients died due to sepsis, renal failure, ARDS and intracranial hemorrhage. The most common grade II-III toxicities were mucositis (74%), nausea/vomiting (59%), and diarrhea (33%). No grade IV non-hematological toxicity was observed. The median follow-up for metastatic and high-risk groups were 14 months (range: 1-30) and 13 months (range: 1-31), respectively. The overall survival rates were 55% in metastatic and 77% in high-risk groups for two years. In conclusion, HDC with APBSCT is a potentially effective treatment for patients with breast cancer but should be given to selected patients to evaluate its efficacy.
