Abstract

PURPOSE: The treatment of small-cell lung cancer patients with good performance status aims to improve survival. Dose-intensification could be a way to achieve improved survival but can be limited by neutropenia and thrombocytopenia. Preliminary, nonrandomized feasibility studies showed that doxorubicin, cyclophosphamide, and etoposide (ACE) could be given every 2 (instead of the usual 3) weeks with granulocyte colony-stimulating factor (G-CSF) (lenograstim; Chugai-Rhône-Poulenc, Tokyo, Japan) support. The present multicenter randomized trial was designed to examine whether such dose-intensification improves survival while maintaining acceptable toxicity levels. PATIENTS AND METHODS: All patients were randomized to receive six cycles of ACE either every 3 weeks (control [C] group) or every 2 weeks with G-CSF (G group). The standard dose-intensity of ACE was increased by 50% in group G. RESULTS: Four hundred and three patients (G group: n = 201; C group: n = 202) were randomized. The received dose-intensity was 34% higher in the G group than in the C group. Complete response rates were 40% for the G group and 28% for the C group (P = .02), and overall rates were 78% for the G group and 79% for the C group. Survival was longer in the G group (hazard ratio = 0.80; 95% confidence interval, 0.65 to 0.99; P = .04), survival rates for the G and C groups being 47% and 39% at 12 months and 13% and 8% at 24 months, respectively. Metastasis-free survival, nonhematologic toxicity, and quality of life were similar in the two groups. In the G group, there was less neutropenia but more thrombocytopenia and more frequent blood and platelet transfusions. CONCLUSION: Increasing the dose-intensity of ACE with G-CSF support improved survival while maintaining acceptable toxicity.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
