Taxane acute pain syndrome (TAPS) is a commonly occurring adverse event after treatment with taxane-based chemotherapy, reducing the quality of life (QOL) and increasing the need for pharmaceutical interventions among patients with cancer, according to a study published in Supportive Care in Cancer.
Despite its prevalence, TAPS — arthralgia and myalgia that occurs shortly after administration of taxane-chemotherapy and lasts for approximately 1 week — does not have an associated validated assessment method and its impact on patient outcomes has not been thoroughly researched.
For this prospective study, researchers enrolled 75 patients with breast (n = 66) or prostate (n = 9) cancer initiating taxane-based chemotherapy to assess the nature and management of TAPS during treatment, and its impact on QOL. Patients were instructed to complete the NCI CTCAE to assess arthralgia/myalgia, and the Functional Assessment of Cancer Therapy-Taxane (FACT-T) and Brief Pain Inventory (BPI) were completed to evaluate QOL; questionnaires were provided at baseline and once between days 5 and 7 of each chemotherapy cycle.
After the first cycle of treatment, TAPS was observed in 36.2% (25 of 69) of patients, and 18.2% (8 of 69) of those patients experienced TAPS after subsequent cycles. Overall, 44% (33 of 75) of patients experienced TAPS throughout therapy.
Patients with TAPS had significantly reduced scores on the FACT-T, nonsignificantly reduced scores on BPI, and increased analgesic utilization (63% [21 of 33 patients]), but did not lead to any changes in chemotherapy dosing.
TAPS occurs in high rates and negatively affects QoL; the authors concluded that “prospective patient-reported outcome assessments are crucial to help individualize treatment strategies and improve management of TAPS.”
