Cohort study reveals higher chemotherapy dose intensity improves survival in testicular cancer, indicating granulocyte colony-stimulating factor supports optimal treatment delivery.

Key Points

To examine the relationship between chemotherapy relative dose intensity and treatment efficacy in testicular cancer, and evaluate the effect of adjunctive granulocyte colony-stimulating factor on maintaining dose intensity.
Retrospective cohort analysis of 33 patients with testicular cancer treated with the PVB regimen (cisplatin, vinblastine, and bleomycin) between 1981 and 1992 (N=25 evaluable).
Calculated relative dose intensity (RDI) for individual drugs and the combination, comparing standard-dose (RDI ≥ 0.9) to modified-dose (RDI < 0.9) groups.
Assessed the impact of granulocyte colony-stimulating factor (G-CSF) co-administration on achieving target RDI.
Among 25 evaluable patients, 20% (n=5) achieved complete response, 60% (n=15) achieved partial response (80% overall response rate), with a 78.4% 5-year overall survival rate.
Bleomycin RDI was significantly higher in complete responders (0.89) and partial responders (0.91) than nonresponders (0.32), and three-drug RDI was similarly elevated in responders (1.05 and 0.97 vs. 0.69), with RDI ≥ 0.9 conferring higher survival than RDI < 0.9.
Patients receiving adjunctive G-CSF achieved a significantly higher mean PVB regimen RDI than those receiving PVB alone (0.98 vs. 0.87, p < 0.01).
