Anticipated administration of GM-CSF in the treatment of non small cell lung cancer.
The purpose of this study was to verify the kinetic response of the human marrow myeloid progenitor cells to the short term use of GM-CSF and its impact on the therapeutic activity of this three-drug cisplatinum containing regimen in non small cell lung cancer (NSCLC). Sixty patients with stage III-B and IV NSCLC were randomised to receive GM-CSF for 3 days, five days prior to the onset of chemotherapy. The chemotherapy regimen consisted of Mitomycin-C: 6 mg/m2 on day one, Ifosfamide: 2000 mg/m2 days 1 to 3, Mesna: 2000 mg/m2 days 1 to 3, Cisplatinum: 30 mg/m2 days 1 to 3, and was repeated every 4 weeks. All the patients received 30-50 Gy of radiotherapy to the primary and/or metastatic sites. There were positive correlations between stage of the disease, chemosensitivity of the tumor, number of chemotherapy cycles and overall survival (p=0.000). Administration of GM-CSF was an independent prognostic parameter in locally advanced and metastatic disease (p=0.041). In the GM-CSF receiving arm more courses could be given (117 versus 99, p=0.0415), and less courses were postponed (6 versus 22). In this arm, the mean of granulocyte nadir was higher (p=0.033) and mean time to granulocyte recovery became shorter (p=0.001) as the number of chemotherapy cycles increased. It was concluded that, dose intensification with GM-CSF prophylaxis is benefical in increasing the treatment tolerability by decreasing the intensity of granulocytopenia as well as providing rapid recovery.
