Neoadjuvant Treatment Real-world Clinical Outcomes in NSCLC
- Conditions
- Non-Small Cell Lung Cancer
- Interventions
- Drug: Neoadjuvant immunochemotherapyDrug: Neoadjuvant chemotherapy
- Registration Number
- NCT05974007
- Brief Summary
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.
- Detailed 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.

Group Intervention Description Resectable stage I-III NSCLC Neoadjuvant chemotherapy Patients with NSCLC patients receiving neoadjuvant therapy and undergoing surgeries. Resectability after neoadjuvant therapy is judged by the multidisciplinary team of thoracic surgeon, oncologist and radiation oncologist. Resectable stage I-III NSCLC Neoadjuvant immunochemotherapy Patients with NSCLC patients receiving neoadjuvant therapy and undergoing surgeries. Resectability after neoadjuvant therapy is judged by the multidisciplinary team of thoracic surgeon, oncologist and radiation oncologist.
- Primary Outcome Measures
Name Time Method Pathological Complete Response (pCR) Within 2 weeks after surgery defined as 0% of viable tumor cells in primary tumor and lymph nodes
Disease-free survival(DFS) DFS was defined as the time from surgery to the appearance of metastasis, up to approximately 5 years. Defined as the time from the date of randomization until the date of disease recurrence or death (by any cause in the absence of recurrence).
- Secondary Outcome Measures
Name Time Method Overall Survival (overall survival) Rate From date of surgery until date of death due to any cause. Assessed at 5 years. OS is defined as the time from surgery tiem until death from any cause, estimated from a Kaplan Meier plot of OS at the time of the primary analysis.
OS (overall survival) From date of surgery until date of death due to any cause, up to approximately 5 years. OS is defined as the time from surgery tiem until death from any cause.
EFS (event-free survival) Up to 5 years after first therapy. EFS was defined as time from study inclusion (first dose date) to disease progression, death, or discontinuation of treatment.
Event Free Survival (event-free survival) Rate From date of first received neoadjuvant therapy to 5 years after neoadjuvant. EFS was defined as time from study inclusion (first dose date) to disease progression, death, or discontinuation of treatment.
Major Pathological Response (MPR) Within 2 weeks after surgery defined as ≤10% of viable tumor cells
Patterns of Relapse Within 5 years after surgery Relapse was defined as disease recurrence at any site.
