A Multi-dimensional Evaluation of the Effects of Linear Accelerator X-ray Irradiation on Red Blood Cells
China20 participantsStarted 2026-01-28
Plain-language summary
This study aims to investigate the effects of linear accelerator X-ray irradiation on the structure, mechanics and functional characteristics of red blood cells recovered from patients with malignant tumors during surgery. A red blood cell damage evaluation system based on multiple-dimensional indicators is established. Through atomic force microscopy, microfluidic chips and biochemical detection methods, the changes in red blood cell membrane structure, deformability and oxygen-carrying capacity under different irradiation doses are systematically evaluated. The dose-effect relationship between irradiation dose and red blood cell damage degree is clarified, providing experimental evidence for the safe dose of irradiation processing of autologous blood during surgery.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Patients scheduled for elective surgery for malignant tumors
* Age: 18 - 65 years old
* It is estimated that the surgical bleeding will be greater than or equal to 500 milliliters.
Exclusion Criteria:
* Disorders of red blood cell production (such as aplastic anemia, megaloblastic anemia, iron deficiency anemia, leukemia, myelofibrosis, etc.)
* Diseases caused by increased destruction of red blood cells (abnormalities in red blood cell membranes such as hereditary spherocytosis and paroxysmal nocturnal hemoglobinuria; abnormalities in hemoglobin such as thalassemia; abnormalities in red blood cell-related enzymes such as glucose-6-phosphate dehydrogenase deficiency, etc.)
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
