Study of Use of CTC in NSCLC

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to assess whether the detection of circulating tumor cells (CTC) could be used as a tool to earlier diagnose, more accurately predict treatment response / failure and predict overall survival in non-small cell lung cancer (NSCLC) patients

Detailed Description
-----------------
Lung cancer remains the most common cause of cancer mortality in the world for both men and women. More than half of patients diagnosed will die within the first year. Given these concerning facts, we are in need of novel methodologies to diagnose patients at earlier stages of the disease, more accurately predict treatment response / failure and predict overall survival. The use of CTC has been investigated and shown to predict progression free survival and overall survival in metastatic breast cancer, and recommended as a breast cancer tumor marker by the American Society of Clinical Oncology. There have also been relationships between CTC's and survival, shown in metastatic colorectal and prostate cancer. However, CTC's have not been thoroughly investigated in non-small cell lung cancer. This trial will assess if the detection of circulating tumor cells could be used as a tool to help further advance treatment for NSCLC patients.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| To estimate the correlation between the number of circulating tumor cells (CTC) and clinical stage of the disease |  | Completed within 6 months of the last sample collected | 
| In Stage I, II or III patients with resectable disease, to obtain preliminary data to assess whether the number of CTC in post operative peripheral blood samples decrease compared with the number of CTC in the pre operative peripheral blood samples |  | Measured up to 12 week post op | 
| To obtain preliminary data to assess whether lower numbers of CTC are associated with a reduction in tumor burden (by RECIST criteria) on imaging |  | Completed within 6 months of the last sample collected | 
| To obtain preliminary data to assess whether there is a decrease in the number of CTC during treatment with chemotherapy in Stage IV disease |  | measured up to completion of 4 cycles of chemo or up to 12 weeks after completion of radiation and chemo treatment | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| To obtain preliminary data on the association of baseline number of CTC and disease-free survival for patients with all stages of disease |  | Will be assessed for up to 2 years after subjects last visit | 
| To obtain preliminary data on the association of baseline number of CTC and overall survival for patients with all stages of disease |  | Will be assessed for up to 2 years after subjects last visit |
