    • Abstract

    Background
    The addition of BV to cytotoxic agent(s) prolonged survival for non-Sq NSCLC patients (pts). However, there is no definitive evidence for the cytotoxic agent(s) plus BV is superior to the cytotoxic agent(s) alone for elderly non-Sq NSCLC. We conducted the feasibility study of PEM plus BV as the first-line treatment for elderly advanced or recurrent non-Sq NSCLC.

    Methods
    Major eligibility and exclusion criteria were followings; chemotherapy-naïve; unfit for bolus combination chemotherapy; stage III/IV or relapsed non-Sq NSCLC; age≥70; PS 0-1; no evidence of brain metastasis; no history of hemoptysis and irradiation for thorax. PEM (500mg/m[2]) and BV (15mg/kg) were administrated intravenously on day 1 every 3 weeks. The primary endpoint was toxicity and the secondary endpoints were objective response rate (ORR), progression-free survival (PFS), overall survival (OS), and the percentage of pts who completed more than 3 cycles.

    Results
    From November 2010 to April 2012, total 12 pts were enrolled. Patients characteristics were following; Male/Female=6/6; Median age (range) 78 (72-81); Histology was all adenocarcinoma; Activating EGFR mutation No/Yes/unknown=9/2/1; Stage IIIB/IV/Recurrence=2/8/2; ECOG PS 0/1=6/6; Smoking History Yes/No=6/6. Severe toxicities (Grade 3≥) were leukopenia (25%), neutropenia (25%), anemia (8%), thrombocytopenia (8%), febrile neutropenia (8%), anorexia (8%), hypertension (8%), fatigue (8%), nausea (8%), and perforation (colon) (8%). No dose-limiting toxicity and treatment-related death was occurred. Three patients achieved PR and the ORR was 25%. The median PFS and OS were 5.6 months (mo) (95% C.I. 1.1-7.9 mo) and 10.3 mo (95% C.I. 6.9-15.6 mo) in 11 evaluated pts, respectively. The 1-year survival rate was 49% (95% C.I. 12-79%). Seven of 12 pts (58%) received more than 3 cycles.

    Conclusion
    PEM plus BV as first-line treatment for elderly non-Sq NSCLC was well tolerable and promising.
