    • Abstract

    Background
    Non-small cell lung cancer (NSCLC) is the most common cancer worldwide. Majority of the patients present with advanced disease. For patients with good performance status, palliative chemotherapy consisting of a platinum-containing doublet has become Standard of care. Cisplatin plus gemcitabine is a viable option in the treatment of metastatic NSCLC. Biweekly use of this regimen has been found to be effective and tolerable in various cancers. Moreover, this schedule offers a more convenient way of administration. We retrospectively evaluated the efficacy and tolerability of this regimen in advanced NSCLC patients.

    Methods
    Medical records of advanced NSCLC patients who were treated with first-line biweekly cisplatin + gemcitabine chemotherapy were analyzed retrospectively. Cisplatin 50 mg/m2 and gemcitabine 1000 mg/m2 were given on day 1 of every 14 days of the cycle. Response rates, survival outcomes and toxicities were recorded.

    Results
    A total of 109 patients were evaluated in six centers of Anatolian Society of Medical Oncology. Of those, 94 patients were men (86%) and 15 were women (14%). The median age was 58 years (range, 25-82). Most of the patients had adenocarcinoma (n=62, 57%). All of them had ≤2 ECOG PS. Median 7 cycles therapy were given (range, 2-12). Patients were evaluated for response usually after every 4 cycles. There was no complete response. Forty-five patients (41%) achieved partial response (PR). Stable disease was observed in 27% of the patients leading to an overall clinical benefit rate of 68%. Median progression-free survival (PFS) was 5.9 months. Median overall survival (OS) was 12.6 months. Eight patients died due to progression during therapy. The most common non-hematologic toxicities were nausea and vomiting. Grade 3/4 toxicity was detected in eight (7%) patients. They were four anemias, two neutropenias, one vomiting and one nephropathy. In all grades, the most common hematologic toxicity was anemia (48%). Neutropenia was seen in 21% of the cases, but only one patient had febrile neutropenia. One patient had to discontinue therapy due to grade 2 nephropathy.

    Conclusion
    Biweekly cisplatin and gemcitabine is an effective and tolerable regimen in the first-line treatment of NSCLC.
