• Overall Response Rate (complete response + partial response) according to the RECIST criteria
  

• Assess duration of response for responding patients: defined as time from when response was first documented until time when progression was documented
  
• Time to progressive disease: defined as interval between trial enrollment and progressive disease or death, whichever occurred first
  
• Survival time-median survival time and 1-year survival: defined as time from study enrollment to date of death or date of last follow-up visit
  
• Assessment of toxicity profile of carboplatin and Abraxane using the National Cancer Institute Common Toxicity Criteria Adverse Events (NCI CTCAE) version 3.0
  

Patients are being asked to be in this study because they have extensive disease small cell lung cancer. All eligible participants who agree to be in the study will receive both abraxane and carboplatin. The researchers want to evaluate the activity and safety of the combination of abraxane and carboplatin, and if this combination can help people with extensive disease small cell lung cancer. Carboplatin is a chemotherapy drug that has been approved by the Food and Drug Administration (FDA) to treat ovarian cancer. It is in a class of drugs known as platinum-containing compounds. It slows or stops the growth of cancer cells in your body. Carboplatin is not approved by the FDA for use in the treatment of small-cell lung cancer, either alone or combined with other anti-cancer drugs. However, carboplatin given with paclitaxel is a standard or active treatment in patients with small cell lung cancer, non-small cell lung cancer, breast cancer, and ovarian cancer. Abraxane is a chemotherapy drug that was approved by the FDA to treat metastatic breast cancer after other chemotherapy has already been tried. Abraxane is a new preparation of the active ingredient in the chemotherapy drug, paclitaxel. In a study done in breast cancer patients, Abraxane was compared to paclitaxel. Abraxane has been shown to be more effective than paclitaxelin tumor response and tumor progression, in addition to having fewer side effects than paclitaxel. Abraxane was shown to cause less damage to a person's white blood cells (the cells that fight infection) and cause fewer allergic reactions; however, more patients developed numbness of their hands and feet.

Carboplatin and Abraxane are intravenous (IV) medications. Patients will begin treatment with 2 cycles (1 cycle = 21 days) of abraxane and carboplating. Then there will be a disease assessment at cycles 2 and 4. Patients with stable disease, partial response, or complete response will get additional cycles. Patients with progressive disease no will be taken off the study treatment. A maximum of 6 cycles will be given.
