Overview
Despite the clinical success of immune checkpoint blockade (ICB), in neoadjuvant setting, there is still a lack of valid data for operable NSCLC in the real world. This study aim to compare the clinical outcomes (pathologic response rate versus survival) of neoadjuvant immunochemotherapy with neoadjuvant chemotherapy in the real world, to explore the impact of clinicopathological factors on clinical outcomes in neoadjuvant immunochemotherapy setting, and to identify potential neoadjuvant immunochemotherapy beneficiaries.
Description
Although the application of neoadjuvant immunotherapy in NSCLC has brought a new treatment option to many patients, most evidence is based on interventional clinical trials, in which the participants are highly selected and the therapeutic strategies are restricted, resulting in limited representation. There is still a lack of large-scale multicenter real-world data to further verify the benefits in long term overall survival, identify the potential beneficiaries and optimize the therapeutic strategies of neoadjuvant immunochemotherapy.
To meet the forementioned need, the investigators will perform a multi-center retrospective cohort to describe the patterns of neoadjuvant immunochemotherapy use in real world, compare the efficacy of neoadjuvant immunochemotherapy ,and evaluate prognosis of neoadjuvant immunochemotherapy.
