PURPOSE: Taxane-associated acute pain syndrome (T-APS) is one of the most bothersome adverse effects caused by taxanes. We have previously reported the attenuating effect of dexamethasone (DEX) on T-APS and its risk factors under DEX prophylaxis. However, the appropriate DEX dosage administration remains unclear. Therefore, this study aimed to investigate whether DEX dose-dependently prevents T-APS in breast cancer patients.
METHODS: We retrospectively evaluated patients with breast cancer who received docetaxel (75 mg/m2)-containing chemotherapy without pegfilgrastim and regular non-steroidal anti-inflammatory drugs. The patients were divided into 4 mg/day and 8 mg/day DEX groups, with each DEX dosage on days 2-4 (n = 68 for each group). Primary endpoint was the comparison of all-grade T-APS incidence between the groups. Propensity score-matching was performed to adjust the baseline factors between the groups, and outcomes in the matched-population were also assessed.
RESULTS: The incidence of all-grade T-APS was 72.1% in 4 mg/day group and 48.5% in 8 mg/day group, which was significantly lowered by higher DEX dosage (P = 0.008). The severity of T-APS was also significantly reduced in 8 mg/day group (P = 0.02). These results were confirmed in the propensity score matching. Multivariate logistic analysis showed that higher DEX dosage was an independent T-APS preventive factor, whereas age < 55 years was a risk factor. Moreover, DEX-dosage-associated adverse effects similarly appeared in both groups.
CONCLUSION: Our study suggested that DEX dose-dependently prevents T-APS in breast cancer treatment. As understanding of the nature of T-APS and its appropriate management can significantly contribute to less onerous chemotherapy provision, further studies are required.
