RESUMO
INTRODUCTION: Docetaxel can cause fluid retention reactions (FRRs) and hypersensitivity reactions (HSRs). The manufacturer recommends a multi-day oral dexamethasone premedication to prevent these toxicities, but steroid related side effects and regimen compliance remain a concern. This study aimed to determine if modified dexamethasone premedication regimens resulted in differences in HSRs or FRRs to docetaxel. We also examined side effects of dexamethasone and delays in chemotherapy. METHODS: A retrospective chart review was conducted on 82 early breast cancer patients treated with docetaxel. Three steroid regimens were examined: IV 20â mg single-dose dexamethasone, or IV 12â mg dexamethasone with either dexamethasone 8â mg BID for three days starting the day before chemotherapy or dexamethasone 4â mg BID for three days following chemotherapy. Adverse effects, delays in chemotherapy, and reasons for delays in chemotherapy were recorded. RESULTS: The incidence and severity of FRRs and HSRs was low, with less than 10% incidence of HSRs or FRRs in any group. Delays were most common in the group receiving dexamethasone 8â mg BID for 3 days starting the day before chemotherapy (63.3%) (p < 0.05) and were most commonly due to patient noncompliance (26%). CONCLUSION: A single dose of intravenous dexamethasone alone or followed by lower doses of oral dexamethasone may improve patient compliance and avoid delays in chemotherapy, without an increase in docetaxel toxicity.
