P. Bojko et al., High-dose chemotherapy with peripheral blood stem cell transplantation forpatients with advanced ovarian cancer, J CANC RES, 127(4), 2001, pp. 243-250
Purpose: We report the results of high-dose chemotherapy (HDC) with periphe
ral blood stem cell transplantation in twenty-one patients with primarily a
dvanced or relapsed ovarian cancer. Methods: Twenty-five women underwent st
em cell collection, and 21 were finally treated with different regimens of
HDC containing cyclophosphamide, etoposide, carboplatin, and treosulfan. Th
e patients received cyclophosphamide +/- cisplatin and cisplatin + paclitax
el, respectively, followed by G-CSF (n = 24) or GM-CSF (n = 1) for stem cel
l mobilization. Results: A mean of 7.2 +/- 6.1 x 10(6) CD34 + cells per kg
bw were collected. Thirteen patients received double transplants and one pa
tient received a triple transplant. The median age was 47 years (range 24-6
1 years) and the mean number of prior regimens was three (range 1-8). Engra
ftment occurred on time in all patients and there was one treatment-related
death resulting in an overall mortality rate of 4.8% among the 21 patients
treated with HDC. The response rate was 72% (48% CR, 24% PR) and the mean
time to progression and overall survival after HDC were 7 and 32 months, re
spectively. Conclusion: HDC could be performed safely in patients with adva
nced ovarian cancer. However, even with a high response rate, the duration
of response is short, warranting new treatment approaches to further improv
e the outcome of this population of patients with unfavorable prognosis.
