    • Abstract

    Background
    

    Amrubicin and cisplatin is one of active regimens for patients with extensive-disease small cell lung cancer (ED-SCLC). Combined modality of combination chemotherapy and concurrent thoracic radiotherapy has been recognized as standard treatment for LD-SCLC. This study aimed to determine the maximum tolerated dose (MTD), and dose limiting toxicity (DLT) of amrubicin and cisplatin with concurrent TRT in LD-SCLC.

    Method
    

    Patients fulfilling the following eligibility criteria were enrolled: chemotherapy-naïve, PS0-1, age =<75, LD-SCLC, and adequate organ function. Patients received escalating doses of amrubicin on days 1, 2, and 3, under a fixed 60 mg/m² of cisplatin on day 1. Four cycles of chemotherapy were repeated every 4 weeks. TRT of once-daily 2Gy/day commenced on day 2 of the first cycle of chemotherapy. The initial doses of amrubicin was 20 mg/m² (level 1), and the dose was escalated to 25 (level 2) and 30 (level 3) mg/m².

    Result
    

    Eight patients were enrolled at three dose levels. male/female=3/5; PS 0/1=4/4; median age (range) =68.5 (60-73). Two of two in level 3 experienced DLTs. The presentation of DLTs was grade4 neutropenia and leukopenia lasting more than four days. The MTD determined level 3, and level 2 was recommended for this combined modality. Evaluation of responses were 7 partial response and 1 progressive disease (response rate 87.5%) and the median overall survival time was 24.7 months, and suggested the regimen seemed to be modest activity.

    Conclusion
    

    In combined modality of this chemotherapy with TRT for LD-SCLC, MTD was amrubicin 30 mg/m² and cisplatin 60 mg/m², and DLTs were neutropenia and leukemia.
