    • Abstract

    Background
    Background: Pemetrexed activity is synergistic with both carboplatin and cisplatin in chemonaive NSCLC patients. Two phase II Pem plus carboplatin trials have confirmed the doublet’s activity in NSCLC and response rates were 31% and 24% (Scagliotti and al 2003, Zinner and al 2005). Carboplatin is a good alternative in unfit patients suggesting a balanced benefit/risk profile when combined with Pem.

    Methods
    Sixty-four patients unfit to receive cisplatin with measurable stage III-B IV NSCLC, received at least one dose of chemotherapy. Pem 500 mg/m2 over 10 min on day 1 with folic acid and vitamin B12 supplementation followed by carboplatin AUC 5 on the same day were given every 21 days for 4- 6 cycles. Primary endpoint was safety and efficacy ( progression free survival)

    Results
    Sixty four patients received at least one dose of chemotherapy. Median age was: 71.3 yrs (86−44,3), 90,6% of patients presented comorbilities , mainly cardiopathy (73,4%) . Stages IIIb: 15,6%, IV: 84,4%. Non squamous cell carcinoma: 100.% (adenocarcinoma: 92,2%, large cell carcinoma: 7.8% )Male 76,6%, female 23,4%. The median number of administered cycles was 4. Median progresion free survival and overall survival will be presented at the meeting. Grade 3/4 toxicities related to study drugs were: asthenia 6.1%, skin 3.1%, dyspnea 3.1% .Hematological grade 3/4 events were: neutropenia: 6.1%, thrombocytopenia: 1,6%, anemia: 14.1%. 10,9% of patients need dose reduction

    Conclusion
    In first line NSCLC, the combination of Pem plus carboplatin could be a valuable treatment alternative in unfit patients to recive cisplatin. Anemia is the most frequent toxicity in this combination.
