Universal tolerance of nab-paclitaxel for gynecologic malignancies in patients with prior taxane hypersensitivity reactions / 부인종양

ABSTRACT

OBJECTIVE: To report on the incidence of nab-paclitaxel hypersensitivity reactions (HSRs) in patients with prior taxane HSR. METHODS: From 2005 to 2015, all patients who received nab-paclitaxel for a gynecologic malignancy were identified. Chart abstraction included pathology, prior therapy, indication for nab-paclitaxel, dosing, response, toxicities including any HSR, and reason for discontinuation of nab-paclitaxel therapy. RESULTS: We identified 37 patients with gynecologic malignancies with a history of paclitaxel HSR who received nab-paclitaxel. Six patients (16.2%) had a prior HSR to both paclitaxel and docetaxel while the other 31 patients had not received docetaxel. No patients experienced a HSR to nab-paclitaxel. Median number of cycles of nab-paclitaxel was 6 (range 2–20). Twelve patients received weekly dosing at 60 to 100 mg/m². The remainder of patients received 135 mg/m² (n=13), 175 mg/m² (n=9), or 225 mg/m² (n=3). Thirty four patients (91.9%) received nab-paclitaxel in combination with carboplatin (n=28, 75.7%), IP cisplatin (n=1, 2.7%), carboplatin and bevacizumab (n=3, 8.1%), or carboplatin and gemcitabine (n=2, 5.4%). Reasons for discontinuing nab-paclitaxel included completion of adjuvant therapy (n=16), progressive disease (n=18), toxicity (n=1), and death (n=1). There were no grade 4 complications identified during nab-paclitaxel administration. Grade 3 complications included neutropenia (n=9), thrombocytopenia (n=4), anemia (n=1), and neurotoxicity (n=1). CONCLUSION: Nab-paclitaxel is well-tolerated with no HSRs observed in this series of patients with prior taxane HSR. Given the important role of taxane therapy in nearly all gynecologic malignancies, administration of nab-paclitaxel should be considered prior to abandoning taxane therapy.
