The clinical efficacy of COP-BLAM chemotherapy combined with human recombinant granulocyte colony-stimulating factor (G-CSF) was evaluated in 104 previously untreated patients with non-Hodgkin's lymphoma (NHL). According to the method of Laurence et al., a modified COP-BLAM regimen was administered every 21 days. G-CSF was added when the granulocyte count fell below 1000 x 10(9)/l. Ninety-eight of 104 (94.2%) patients achieved a complete remission; the 4-year survival rate was 82.4% with a median duration of observation of 26 months. Survival was significantly longer in patients with low serum LDH levels, B-cell type or low CRP or in earlier clinical stages, than in patients with high serum LDH levels, T-cell type of higher CRP levels or in advanced clinical stages. The mean duration of administration of G-CSF was 5.4 days. Twelve patients developed infections during treatment. The adverse effects of G-CSF included interstitial pneumonia, bone pain and fever. Patients administered COP-BLAM combined with G-CSF achieved a high rate of remission and had a low incidence of infection. Nearly all the patients could be treated in 21-day cycles. The results suggest that G-CSF combined with COP-BLAM was effective in treating NHL, because the patients can tolerate a higher dose of the anticancer agents.
