The primary purpose of this non-interventional, multinational study is to assess the feasibility of assessing PD-L1 protein expression on cytological samples as a surrogate for histological samples obtained from participants with any stage of non-small cell lung cancer (NSCLC) or small cell lung cancer (SCLC).
A Non-Interventional Multinational Study to Assess PD-L1 Expression in Cytological Versus Histological Non-Small Cell or Small Cell Lung Cancer Specimens
- Samples must have been collected in a manner that is compliant with local ethics committee guidance
- Samples must originate from participants diagnosed with NSCLC or SCLC
- Participants must have a pair of at least one cytological and one histological specimen that: Both originate from inside the thorax or from the same ex-thoracic site; Are confirmed to have been collected within a window no more than 6 weeks apart from each other; and are in compliance with the protocol defined sample requirements for histological and cytological specimens
- Immune checkpoint inhibitor therapy from 4 weeks prior to collection of the first tumor sample until collection of the second matched sample
