title: [Chemotherapy-associated myelosuppression in gynecological oncology].
abstract: OBJECTIVE
  A clinically important myelosuppression due to adjuvant chemotherapy is seen more frequently as dosage is intensified and new drugs are used. The assessment of the cytopenia expected is frequently hampered by a lack of directly comparable data. The aim of this study was to compare - in our own patient population - the chemotherapy-associated myelosuppression of four chemotherapeutic regimens used in gynecological oncology.
  
  
  METHODS
  79 patients with primary breast cancer and 26 patients with epithelial ovarian carcinoma underwent cytostatic treatment, and the associated myelosuppression was evaluated by the determination of cytopenia and the need for supportive therapy. The chemotherapy regimens investigated were CMF (cyclophosphamide 600 mg/m(2), methotrexate 40 mg/m(2), 5-fluorouracil 600 mg/m(2), 6xq3w), EC/CMF (epirubicin 90 mg/m(2), cyclophosphamide 600 mg/m(2), 4xq3w, followed by CMF, 3xq3w), DE (docetaxel 75 mg/m(2), epirubicin 90 mg/m(2), 6xq3w) and CC (cyclophosphamide 600 mg/m(2), carboplatin AUC 6, 6xq3w).
  
  
  RESULTS
  The EC/CMF and DE regimens were used significantly more frequently for more advanced tumor stages, but there were no differences concerning tumor-dependent prechemotherapeutic myelosuppression. Hemopoiesis was most impaired in the CC group with a mean drop of serum hemoglobin of 1.5 g/dl to the end of the cytostatic treatment; correspondingly, most transfusions of concentrated erythrocytes were needed in this group. The strongest suppression of leukopoiesis was found in the DE group, with a mean drop in leukocyte counts of 6.2 x 10(3)/microliter per cycle; in this group, a mean of 7.6 ready-made syringes with 263 microgram Lenogastrim was used to stimulate leukopoiesis. The severest drop in the mean thrombocyte count, i.e. 171.7 x 10(3)/microliter, was found in the CC group.
  
  
  CONCLUSIONS
  The CC regimen impairs thrombo- and erythropoiesis most, whereas the DE regimen causes marked leukopenia. The regimen with the smallest myelosuppression was CMF. No severe cytopenia-associated complications were detected in any of the cases investigated.
