Consistency Analysis of PD-L1s in Non-small Cell Lung Cancer Patients' Cancer Tissues and in Plasma Exosomes Before and After Radiotherapy:A Clinical Trial

The detection of tissue PD-L1 immunohistochemistry in NSCLC has an important role in guiding for the treatment of immune detection point.Radiation therapy can enhance the effect of immunotherapy,but radiation dose and timing are waiting to be solved. At the same time,tissue detection is time-consuming and laborious, liquid biopsy can reflect the information of tumor tissue,PD-L1 mRNA in plasma exosomes (pExo) is expected to be simple, rapid, non-invasive means of detection. The project is planned to explore the consistency analysis of PD-L1 expression level detected in advanced non-small cell cancer patients' cancer tissues and pExo before and after radiotherapy.The investigators have designed five kinds of radiation-division with bioequivalent doses, and detected the expression levels of PD-L1 in pExo after 24h, 48h of each stage of radiotherapy.PD-L1 mRNA levels in pExo detected at different time points,by using variance analysis of repeated measures design information.Probing the best timing and manner of radiotherapy division which can make PD-L1 express more,guiding clinical practice of radiotherapy combining with immunotherapy.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
