The Molecular Screening Study for the Umbrella Trial (SUKSES) in Relapsed Small Cell Lung Cancer Patients [SUKSES-S]

This protocol is a molecular screening protocol only. No drug intervention study will be included in this protocol. Based on the molecular profiling, patients may be eligible for drug intervention study of SUKSES trial. This procedure (molecular profiling) can be performed before, during, or after the initial treatment. DNA will be extracted from the archived or fresh tissue and blood. NGS-based cancer panel and Nanostring CNV will be tested with DNA from tissue and/or blood. Immunohistochemistry and FISH will be done by pathologists using archived or fresh tissue. In addition, blood collection will be conducted at Baseline (initial), three weeks, six weeks, twelve weeks, and subsequent imaging. Tumor tissues (fresh or archival) will be analyzed using NGS-based cancer panel, nanostring CNV, immunohistochemistry and/or FISH. Specific methods of each molecular tests will be defined with standard laboratory manual developed by pathologists.
