Single agent docetaxel plus granulocyte-colony stimulating factor (G-CSF) in previously treated patients with advanced non small cell lung cancer. A phase II study and review of the literature.
The use of salvage chemotherapy in advanced non small cell lung cancer (NSCLC) is controversial. However, many patients need to be treated in order to achieve relief of their symptoms. Docetaxel (taxotere) is one of the most active drugs for the treatment of advanced NSCLC and several studies have also shown its effectiveness in pretreated patients. In the present study, 23 patients were treated in order to evaluate both the effectiveness and toxicity of the single agent docetaxel. Furthermore, granulocyte-colony stimulating (G-CSF) factor was administered in order to reduce neutropenia related to docetaxel. Docetaxel was administered intravenously at a dose of 100 mg/m2, on day 1, and it was repeated every 3 weeks. G-CSF was administered for primary prophylaxis of neutropenia at the standard dose of 30 mg/day from day 4 to day 10 of each cycle. The treatment was tolerated well and 5 (21.7%) partial responses were obtained. The median time to progression and the median survival time were 3 and 5 months, respectively. The main side effect noted was fatigue, the intensity of which was grade 2 in 43.4% of cases and grade 3 in 8.7% of patients, respectively. One patient (4.3%) had grade 4 cutaneous toxicity. No cases of grade 4 neutropenia were reported. In conclusion, docetaxel is active when used for salvage chemotherapy in advanced NSCLC whilst concurrent primary prophylactic administration of granulocyte-colony stimulating factor seems to decrease severe neutropenia.
