NSCLC

Brief summary

This study is an open, prospective and observational clinical trial. Adopting a prospective cohort study design, it selects patients with non-small cell lung cancer who receive neoadjuvant immunotherapy as the research subjects. Through systematic follow-up, it monitors the dynamic changes of cortisol levels of patients at different treatment stages and after surgery, and analyzes the associations between these changes and disease progression, treatment effect and adverse reactions.

Detailed description

This is a single-center prospective observational cohort study. No experimental intervention will be performed on the participants, all clinical treatments and examinations are fully in accordance with the routine clinical diagnosis and treatment specifications for resectable non-small cell lung cancer. We only prospectively collect the clinical data and laboratory test results of the participants to analyze the correlation between perioperative dynamic changes of cortisol and the outcomes of neoadjuvant immunochemotherapy.

Inclusion criteria

1. Histologically confirmed primary non-small cell lung cancer (NSCLC), with clinical stage ⅡA-ⅢB resectable/potentially resectable disease, assessed according to the 8th edition of the American Joint Committee on Cancer (AJCC) TNM staging system. 2. Aged 18 to 75 years old, with Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1. 3. Planned to receive standard neoadjuvant PD-1/PD-L1 immune checkpoint inhibitor combined with platinum-based doublet chemotherapy, followed by radical surgical resection. 4. Have complete clinical data, and can complete the scheduled perioperative blood tests (including serum cortisol and ACTH level detection) and follow-up visits according to the study protocol. 5. Voluntarily participate in this study, sign the written informed consent form, and are willing to cooperate with the research team to complete the study-related examinations and follow-up.

Exclusion criteria

1. Patients with confirmed pituitary or adrenal diseases, or abnormal baseline serum cortisol/ACTH levels outside the normal reference range before enrollment. 2. Patients with a history of long-term systemic glucocorticoid use within 3 months before enrollment, or perioperative glucocorticoid use before the postoperative cortisol test. 3. Patients with a history of other primary malignant tumors within 5 years before enrollment (except for cured basal cell carcinoma of the skin or cervical carcinoma in situ). 4. Patients with severe autoimmune diseases, severe liver and kidney dysfunction, severe cardiovascular and cerebrovascular diseases, or other comorbidities that cannot tolerate neoadjuvant therapy and radical surgery. 5. Patients who did not receive radical surgical resection after neoadjuvant therapy. 6. Patients with incomplete clinical data, who cannot complete the scheduled blood tests or follow-up visits. 7. Pregnant or lactating women. 8. Patients with mental illness or other conditions that cannot comply with the study protocol.

Design outcomes

Primary

MeasureTime frameDescription
Major Pathological Response (MPR) RateWithin 30 days after radical surgeryProportion of patients who achieved major pathological response, defined as viable residual tumor cells ≤10% in the resected primary tumor specimen after neoadjuvant immunochemotherapy, assessed according to IASLC standardized criteria.

Secondary

MeasureTime frameDescription
Correlation Between Perioperative Cortisol Dynamic Changes and Pathological ResponseFrom baseline (within 7 days before neoadjuvant treatment initiation) to 7 days after radical surgeryThe correlation between the relative change rate of serum cortisol (from baseline before neoadjuvant therapy to 1 day after surgery) and the proportion of residual viable tumor cells, as well as the achievement of MPR/pCR.
Incidence of Immune Checkpoint Inhibitor (ICIs)-Related Adrenocortical DysfunctionFrom neoadjuvant treatment initiation to 12 months after surgeryThe cumulative incidence of ICIs-related secondary adrenocortical dysfunction, including clinical and subclinical adrenocortical insufficiency, confirmed by serum cortisol and adrenocorticotropic hormone (ACTH) test results, assessed according to the Endocrine Society Clinical Practice Guidelines.
