Abstract
-
PURPOSE: To establish the feasibility of high dose ifosfamide, carboplatin, and etoposide (ICE) chemotherapy followed by autologous stem cell transplantation (ASCT) in patients with high-risk or metastatic breast cancer.
MATERIALS AND METHODS
High-risk breast cancer is defined as 10 or more involved axillary
lymph nodes (n=3) or stage III (n=2). Patients with metastatic cancer have relapsed diseases after curative resection (n=10) or initially metastatic lesion (n=1). Colony stimulating factor with either cyclophosphamide or combination chemotherapy was administered to mobilize the stem cells.
High dose chemotherapy consisted of ifosfamide 16 g/m2, carboplatin 1.8 g/m2, and etoposide
0.75 g/m2 (dose I) and later modified to ifosfamide 12 g/m2, carboplatin 1.35 g/m2, and etoposide 1.2 g/m2 (dose II).
RESULTS
The median duration of grunulocyte nadir (<500/ microliter) was 11 (10~17) days and platelet
transfusion dependency (<20,000/ microliter) was 11 (7~53) days in 14 patients who achieved
engraftment. One out of 5 patients with high-risk breast cancer relapsed after high dose therapy.
Two patients remain disease-free at 18th and 40th months. Two among the 4 patients treated
with dose I died due to treatment-related complications. The responses of metastatic diseases to ICE chemotherapy were 1 continuing CR, 1 CR, 1 PR, 4 SD and 3 PD in 10 evaluable patients.
CONCLUSION
High dose ICE chemotherapy, especially dose II and ASCT were feasible in
high-risk or metastatic breast cancer.
