Proteomics in Small Cell Lung Cancer

This study is analyzing proteins in blood and tumor samples from people newly diagnosed with small cell lung cancer. The goal is to find biological patterns (called proteomics) that might predict how well standard chemotherapy works, and to better understand this aggressive cancer. **You may be eligible if...** - You have been newly diagnosed with small cell lung cancer confirmed by a pathologist - You have measurable cancer visible on a CT scan - You are eligible to receive standard chemotherapy with carboplatin and etoposide **You may NOT be eligible if...** - You have an active second cancer (other than minor skin cancer or early cervical cancer) - You have been previously treated for any cancer - You are currently taking anticoagulant medications (blood thinners — though aspirin and clopidogrel are allowed) - You are currently participating in another clinical drug trial Talk to your doctor to see if this trial is right for you.
