Weekly paclitaxel for advanced non-small cell lung cancer patients not suitable for platinum-based therapy.
Platinum-based combinations are efficacious in the treatment of advanced non-small cell lung cancer (NSCLC) but their toxicity makes them unsuitable for elderly and for patients with co-morbidities. We assessed the efficacy and toxicity of low-dose of paclitaxel in patients who were elderly or who had contraindications against cisplatin therapy. Seventy-one patients (median age 68; range 42-82 years) with unresectable NSCLC were treated with weekly paclitaxel (80 mg/m2) infusion (1 h) for several cycles without intervening rest periods. Thirty-seven patients had PS 1 and 34 had PS 2 status. A total of 614 courses were administered (median 9, range 2-20). There were no episodes of grade 4 toxicities and only 1 patient had grade 3 thrombopenia. Grade 3 anemia or neutropenia were not observed and severe non-hematological toxicity was uncommon: grade 1-2 fatigue in 52%; grade 1-2 motor neuropathy in 42% and grade 3 in 5.5%; grade 1-2 sensory neuropathy in 46.3% of patients. Twenty-seven of the 67 evaluable patients (40.3%) had an objective response, whereas 26 patients (38.8%) had stable disease. The median overall survival for the entire group was 8.4 months (95% CI = 5.6 to 11.2) and the 1-year and 2-year survival was 37.4% and 12.1%, respectively. The median time-to-progression was 5.4 months (95% CI = 3.3 to 7.4). Our data show that low-dose weekly paclitaxel is active and well tolerated in this group of patients with NSCLC and poor prognosis and, as such, is useful for patients in whom platinum-based combinations are not suitable.
