Differences in blood microRNA and circulating tumor cells during immunotherapy

The Difference of microRNA Signature(S) and Circulating Tumor Cells in Blood Among Cancer Patients Before and Afte Immunotherapy

Chang Gung Memorial Hospital · NCT07260370

This project will test whether levels of microRNA and circulating tumor cells in the blood change before and after immunotherapy in adults with cancer.

What this trial studies

This observational project will enroll 300 adults with physician-diagnosed cancer who are starting immunotherapy. Participants will give small blood samples (two 10 mL tubes, up to three times) before and after treatment and investigators may review existing pathology tissue when needed. The project will compare quantities of free microRNAs, counts of circulating tumor cells, and surface antigen expression on both blood cells and available tumor tissue. Statistical analyses will identify patterns that correlate with treatment status and antigen expression.

Who should consider this trial

Good fit: Adults aged 20 or older who have been diagnosed with cancer and are scheduled to receive immunotherapy and can give informed consent are ideal candidates.

Not a fit: Patients under age 20, those who decline participation, or those unable to provide the required blood samples are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, the results could help clinicians use blood-based microRNA and circulating tumor cell measurements to monitor or predict response to immunotherapy.

How similar studies have performed: Previous research has shown that circulating tumor cells and microRNA can reflect cancer biology and sometimes predict therapy response, but findings have been mixed and these biomarkers are not yet standard clinical tools.
