Gemcitabine plus vinorelbine in elderly or unfit patients with non-small cell lung cancer

Cisplatin-based combinations are efficacious in increasing the overall survival of patients with non-small cell lung cancer (NSCLC), but their toxicity makes them unsuitable for elderly and unfit patients. The primary objective of this non-randomized phase II study was to evaluate the feasibility and activity of the gemcitabine plus vinorelbine combination in previously untreated elderly and/or unfit patients with measurable stage III or IV NSCLC. Forty-three patients aged ≥ 65 years or with contraindications against cisplatin treatment (36 males and seven females: median age 66 years; range 48–75: PS 0 = 11, PS 1 = 19, PS 2 = 13) received intravenous (i.v.) gemcitabine 1000 mg m–2, followed by vinorelbine 25 mg m–2i.v. on day 1 and 8 every 21 days. Fifteen patients (34.9%) achieved partial remission (confidence interval: 27.6–42.2%) for a median duration of 6 months; the median survival of these patients has not yet been reached. A further 15 had stable disease for a median of 4 months and a median survival of 7 months. The 10 patients (23.2%) who experienced disease progression had a median survival of 4 months. Three patients are not evaluable. The 1-year actuarial survival rate is 31.1%. The treatment was well tolerated: only 35% of the patients had grade 3 or 4 granulocytopenia on day 14, none experienced episodes of neutropenic fever, and there was no evidence of severe haematological toxicity upon recycling. Only 9% of the patients suffered from gastrointestinal toxicity (grade 3); increased but reversible transaminase levels were observed in 11.6%. In conclusion, the results of this phase II study show that the combination of gemcitabine and vinorelbine is active and well tolerated in NSCLC, and thus encourage its use in elderly or unfit patients. © 2000 Cancer Research Campaig

Addition of either lonidamine or granulocyte colony-stimulating factor does not improve survival in early breast cancer patients treated with high-dose epirubicin and cyclophosphamide

Purpose : Lonidamine (LND) can enhance the activity of anthracyclines in patients with metastatic breast cancer. A multicenter, prospective, randomized trial was designed to determine whether the association of LND with high-dose epirubicin plus cyclophosphamide (EC) could improve disease-free survival (DFS) in patients with early breast cancer (BC) compared with EC alone. Granulocyte colony-stimulating factor (G-CSF) was added to maintain the EC dose-intensity. Patients and Methods: From October 1991 to April 1994, 506 patients with stage I/II BC Were randomly assigned to four groups: (A) epirubicin 120 mg/m(2) and cyclophosphamide 600 mg/m(2) administered intravenously on day 1 every 21 days for four cycles (124 patients); (B) EC plus LND 450 mg/d administered orally (125 patients); (C) EC plus G-CSF administered subcutaneously (129 patients); (D) EC plus LND plus G-CSF (128 patients). Results: Median follow-up was 55 months. Five-year DFS rate was similar for LND (B+D groups; 69.6%) versus non-LND arms (A+C groups; 70.3%) and G-CSF (C+D groups; 67.2%) versus non-G-CSF arms (A+B groups; 72.9%). Five-year overall survival (OS) was comparable in LND (79.1%) versus nonAND arms (81.3%) and in G-CSF (80.6%) versus non-G-CSF arms (79.6%). DFS and OS distributions in LND and G-CSF arms did not change according to tumor size, node, receptor, and menopausal status. G-CSF dramatically reduced hematologic toxicity without having a significant impact on dose-intensity (98.1% v 95.5% for C+D and A+B groups, respectively). Conclusion: EC is active and well tolerated in patients with. early breast cancer. The addition of LND or G-CSF does not improve DFS or OS. (C) 2003 by American Society of Clinical Oncology
