Efficacy and safety of Abraxane in treatment of progressive and recurrent non‐small cell lung cancer patients: A retrospective clinical study

BACKGROUND: Abraxane is a novel Cremophor-free nanoparticle paclitaxel that has been demonstrated to improve efficacy in the treatment of solid tumors. We undertook this retrospective study to evaluate the efficacy and safety of Abraxane in the progressive or recurrent non-small cell lung cancer (NSCLC) patients. METHODS: , d1, and were evaluated for efficacy and safety. The treatment was repeated every three weeks unless progressive lesions or unacceptable toxicities were found. RESULTS: There were no complete response and 11 partial responses (33.3%). Patients with squamous cell carcinoma showed better responses than those with adenocarcinoma (41.7% and 21.1%, respectively). Fourteen patients had stable disease, and the disease control rate was 75.8%. The median progression-free survival was five months (95% confidence interval [CI]: 3.5-6.5). Four patients (12.1%) experienced grade 3-4 hematologic toxicities; one anemia (3.0%), two leucopenia (6.1%) and one thrombocytopenia (3.0%). Six patients (18.2%) experienced grade 3-4 non-hematologic toxicities; two abnormal hepatic functions (6.1%), one fatigue (3.0%), one peripheral neuropathy (3.0%), and two alopecia (6.1%). CONCLUSION: Recurrent and progressive NSCLC patients pretreated with platinum-based chemotherapy might benefit from Abraxane with tolerable adverse events.
