Combination Anticancer Therapy of Paclitaxel and Everolimus for Relapsed or Refractory Small Cell Lung Cancer

Small cell lung cancer (SCLC) accounts for 15% to 20% of all lung cancer, and more than half of these patients are diagnosed with extensive-stage disease (ED). SCLC is a particularly aggressive form of lung cancer with a tendency for rapid tumor growth, early dissemination and high frequency of the metastasis In this study, we evaluate the MTD of everolimus combined with paclitaxel combination chemotherapy in SCLC.

Inclusion criteria

• Patients with histologically or cytologically confirmed small cell lung cancer
• Regarding a limited disease, the disease in a patient, who had concurrent chemoradiation therapy before, is relapsed or progressing, the patient should have received the first line platinum-based anticancer therapy. The disease should be progressing/relapsed during or after the previous treatment.
• Regarding an extensive disease, the progression/relapse of the disease during or after the first line platinum-based anticancer therapy should be confirmed.
