[Significance of stem cell-supported high-dose chemotherapy in the treatment of gynecological malignancies: indications and current clinical trials in the Federal Republic of Germany].

The use of hematopoetic growth factors and stem cell support reduces the dose limiting hematopoetic toxicity's, resulting in a remarkable increase in dose intensity of chemotherapy. As far as data from phase I/II trials are available high dose chemotherapy (HDC) may be integrated in the systemic treatment of breast and ovarian cancers. In metastatic breast cancer HDC may induce fairly high but short response rates. Long term survival is expected in 20% of the cases. Patients with limited metastatic disease, without significant prior chemotherapy, partial or complete response to induction chemotherapy and complete remission after HDC may benefit from HDC. In phase I/II trials HDC improved recurrence free survival in high risk patients (e.g. > 9 positive LN) compared to historic controls and may therefore be a curative approach. Ovarian cancer is very chemosensitive. Conventional chemotherapies induce multidrug resistance rapidly. Just as in breast cancer-Phase I/II trials demonstrated high response rates to HDC, which again were short of duration.
