March 18, 2023 updated by: Liu Wenliang, Second Xiangya Hospital of Central South University

Circulating Tumor DNA (ctDNA) Dynamic Monitoring Plus Artificial Intelligence (AI)-Based Pathology Predict the Efficacy of Chemoimmunotherapy in Resectable Lung Squamous Cell Carcinoma (LSCC)

The goal of this observational study is to explore whether ctDNA dynamic monitoring plus AI-based pathology can more effectively predict the therapeutic effect of neoadjuvant chemoimmunotherapy for resectable lung squamous cell carcinoma, so as to accurately guide clinical diagnosis and treatment.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study is a single-center, observational, non-interventional, prospective study. 50 patients diagnosed with lung squamous cell carcinoma receiving neoadjuvant chemoimmunotherapy (ranging 2 to 4 cycles) will be planned to be enrolled in the study. Pre-treatment biopsy tissues of enrolled patients will be collected for whole exon sequencing (WES) testing, and personalized detection panel will be customized based on WES testing results. Peripheral blood will be collected 1 day before each cycle of neoadjuvant therapy, 1 day before surgery, 3 days after surgery, and 3 weeks after surgery for ctDNA testing. In addition, the prediction model of AI-based pathology will be constructed by AI deep learning based on pathological sections of pre-treatment biopsy tissues. All inclued patients will be regularly followed up for at least 5 years.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Pathologic completet response (pCR) rate
Time Frame: Up to 1 year
pCR rate is defined as the percentage of participants having an absence of residual tumor cells in resected lung specimens and lymph nodes following completion of neoadjuvant therapy.
Up to 1 year
ctDNA resolution
Time Frame: Up to 2 years
ctDNA resolution is defined as the change or resolution in tumor-derived DNA found in the bloodstream from diagnosis to after neoadjuvant therapy and after surgery, correlated with pathologic complete response (pCR)
Up to 2 years
Development of computer algorithm to identify pCR features
Time Frame: From retrospective data collection to algorithm development (6 month)
Development of computer algorithm to identify pCR features
From retrospective data collection to algorithm development (6 month)
Validation of computer algorithm to identify pCR features
Time Frame: From prospective data collection to algorithm validation (6 months)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Perioperative complications rate
Time Frame: Up to 3 years
Number of participants experiencing perioperative complications will be recorded.
