Premedication with dexamethasone is an essential part of the prevention of hypersensitivity reaction (HSR) associated with taxane administration. However, the possibility of stopping dexamethasone premedication has been investigated in previous studies to reduce the steroid's adverse events; however, either the result or the particular protocol was limited. Thus, our study aimed to evaluate the incidence of HSR after dexamethasone premedication discontinuation after lack of HSR in two previous weekly paclitaxel infusions. Early breast cancer patients who received adjuvant weekly paclitaxel in a retrospective cohort from January 2012 through February 2016 at the King Chulalongkorn Memorial Hospital were reviewed. All patients received a standard premedication protocol prior to the first and second paclitaxel infusion. Dexamethasone was omitted in later cycles in all patients who did not undergo infusion HSR. Patients who developed HSR during the first or second cycles of paclitaxel infusion were excluded. The incidence of HSR during the later cycle of paclitaxel administration and factors associated with this adverse reaction were collected. Eighty-one of 85 patients who did not undergo infusion HSR after 2 cycles of weekly paclitaxel administration were retrospectively reviewed. The median age was 51 years (range 27-74 years). Only 16% of the patients had a BMI greater than 30 kg/m(2), 57.8% were premenopausal, 67.9% had no comorbidity, none had a history of allergy or asthma, 65.4% received weekly paclitaxel as a single agent, and 34.6% received weekly paclitaxel in combination with trastuzumab. Five of 81 patients reported grade I-II HSR (6.25%), which occurred mostly during the first 6 cycles (60%). Temporary discontinuation of paclitaxel infusion was observed in all HSR patients. No differences regarding age, BMI, menopausal status, and underlying disease between the HSR and no HSR groups were identified. Concerning the safety profile, peripheral neuropathy (gr I 60%, gr II 13.5%, and gr III 2.4%), myalgia (43.4%), and edema (10.5%) were commonly reported, whereas dyspepsia (5.3%) and insomnia (14.5%) were rarely described in withholding patients. Withholding dexamethasone premedication in non-experiencing HSR patients after two previous cycles of weekly paclitaxel administration was safe and did not impact the higher incidence of HSR. A discontinuing dexamethasone protocol should be recommended generally in these patients, especially those with a high risk for steroid-induced side effects.
