Study Description

Brief Summary:

This study aims to dynamically monitor the expression profile status of peripheral blood mononuclear cells (PBMC) and the changes in circulating tumor DNA (ctDNA) levels in patients with stage III locally advanced unresectable non-small-cell lung cancer(NSCLC) after concurrent chemoradiotherapy or sequential chemoradiotherapy, and to explore biomarkers related to the immune microenvironment and the optimal time point for immunotherapy after chemoradiotherapy.

Condition or disease	Intervention/treatment
Non-small Cell Lung Cancer Stage III	Genetic: biomarker detection

Study Design

• Study Type: Observational
• Estimated Enrollment: 50 participants
• Observational Model: Case-Only
• Time Perspective: Prospective
• Official Title: Dynamic Biomarkers of Immune Microenvironment for Stage III Locally Advanced Unresectable Non-small-cell Lung Cancer
• Estimated Study Start Date: February 2021
• Estimated Primary Completion Date: July 2022
• Estimated Study Completion Date: December 2022

Groups and Cohorts

Group/Cohort	Intervention/treatment
chemoradiotherapy	Genetic: biomarker detection; PBMC and ctDNA analysis

Outcome Measures

Primary Outcome Measures :

1. Biomarkers associated with immune efficacy [ Time Frame: up to 2 years ]
   According to the biomarker detection before and after chemoradiotherapy to identify biomarkers related to the immune microenvironment, including the expression levels of NK cells, T cells, B cells and other immune cells reflected by PBMC, as well as the expression levels of ctDNA
2. Optimal time for immunotherapy [ Time Frame: up to 2 years ]
   Changes in the expression levels of ctDNA and PBMC immune cells before and after chemoradiotherapy to find the optimal time point for immunotherapy

Eligibility Criteria

• Ages Eligible for Study: 18 Years to 70 Years (Adult, Older Adult)
• Sexes Eligible for Study: All
• Accepts Healthy Volunteers: No
• Sampling Method: Non-Probability Sample
