Longitudinal Monitoring of Tumor Specific Mutations in Patients With Lung Cancer
DescriptionPRIMARY OBJECTIVES: I. To evaluate the ability of next generation sequencing (NGS) to monitor the evolution of cancer-specific mutations in patients undergoing treatment for non-small cell lung carcinoma and for whom the molecular profile of the tumor cells prior to treatment is known. II. Compare the sensitivity of digital droplet polymerase chain reaction (ddPCR) to that of NGS for detecting the appearance of EGFR T790M mutations in patients treated with an EGFR tyrosine kinase inhibitor. OUTLINE: Patients undergo collection of blood samples at baseline and every 12 weeks for up to 6 times.
Inclusion and Exclusion Criteria
- A diagnosis of non-small cell lung carcinoma for which the molecular profile of the primary tumor has been obtained from a block of paraffin-embedded, formalin-fixed tissue that remains available
- Zubrod performance status 0 or 1
- Patients must have metastatic or unresectable disease and be starting a new line of systemic treatment at the time of enrollment; there are no constraints regarding the time interval between the initial collection of samples for molecular profiling studies at the time of diagnosis prior to treatment and subsequent collections of circulating cell-free deoxyribonucleic acid (DNA) or circulating tumor cells
- Patients must have measurable disease according to Response Evaluation Criteria in Solid Tumors (RECIST) version (v)1.1
- Ability to understand and the willingness to sign a written informed consent; Note: There will be no discrimination between type of treatment or whether they are on continuous versus intermittent therapy
- Known severe anemia (hemoglobin [Hb] < 8g/dL)
- Patients will be excluded if trackable driver mutations are not identified in the primary tumor tissue
