What this trial studies

This clinical study investigates the optimal number of fiducial markers used in stereotactic body radiotherapy (SBRT) for patients with malignant tumors, specifically lung, liver, pancreatic, and renal cancers. It is a prospective, single-center observational study aiming to enroll 15 patients for each tumor type. Participants will receive SBRT with fiducial markers implanted according to the study protocol, and their progress will be monitored throughout the treatment. Informed consent will be obtained from all participants prior to enrollment.

Who should consider this trial

Good fit: Ideal candidates include patients diagnosed with lung, liver, pancreatic, or renal cell carcinoma who are scheduled to undergo SBRT.

Not a fit: Patients with anatomical challenges for needle insertion or those with poor organ function may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the precision and effectiveness of radiotherapy for various types of cancer.

How similar studies have performed: While the use of fiducial markers in SBRT has been explored, this specific approach to determining the optimal number is relatively novel.
