A prospective multi-centre, randomized study comparing the addition of tapering dexamethasone to other standard of care therapies for taxane-associated pain syndrome (TAPS) in breast cancer patients.

Taxane-associated pain syndrome (TAPS) is common with docetaxel and is characterised by myalgias and arthralgias starting 2-3 days after treatment and can last for up to 7 days. Anecdotal evidence suggests that corticosteroids can reduce TAPS. This multicentre, randomized trial evaluated the effect of additional tapering dexamethasone on TAPS. 130 breast cancer patients commencing docetaxel were randomized to dexamethasone premedication (8 mg/twice daily for 3 days) or dexamethasone premedication followed by tapering dexamethasone (4 mg/daily for 2 days followed by 2 mg/daily for 2 days). The primary endpoint was absolute change in FACT-Taxane questionnaire during the first chemotherapy cycle. Secondary endpoints: proportion of patients with clinically significant TAPS, QoL, pain and toxicity. 110/130 patients had complete data included in the primary analysis. The fall in FACT-Taxane scores was lower in the experimental group on day 5 (p = 0.05), but not on day 7 (p = 0.21). There was no difference in FACT-Taxane scores over the entire study duration (p = 0.59). Fewer patients in the experimental arm reported TAPS on day 5 (30 vs. 47%). There was a borderline significant attenuation of impairment of QoL with experimental treatment on day 5 (p = 0.06), but not day 7 (p = 0.53). Tapered schedule was associated with more dyspepsia and insomnia. A tapering schedule of dexamethasone was associated with a brief reduction in docetaxel-associated symptoms which was observed only during dexamethasone exposure and did not persist after discontinuation of the drug.
