Radiosensitizer - Wikipedia
A radiosensitizer is an agent that makes tumor cells more sensitive to radiation therapy. It is sometimes also known as a radiation sensitizer or radio-enhancer. Conventional chemotherapeutics are currently being used in conjunction …
What is a Radiosensitizer and How Is It Used in Radiation Therapy?
2018年1月11日 · A radiosensitizer, or a radiosensitizing agent, is a drug that makes cancer cells more vulnerable to radiation therapy. Radiation therapy uses high-energy radiation to shrink tumors by disrupting the DNA of cancer cells, causing them to die.
Radiosensitizer - an overview | ScienceDirect Topics
Radiosensitizers are drugs or chemical compounds that enhance the lethal effects of radiation. Importantly, a good radiosensitizer must have a favorable therapeutic ratio. In other words, it must have a differential effect between tumors and normal tissues to be clinically useful.
Definition of radiosensitizer - NCI Dictionary of Cancer Terms
Also called radiosensitizing agent. Any substance that makes tumor cells easier to kill with radiation therapy. Some radiosensitizers are being studied in the treatment of cancer.
Natural Radiosensitizers in Radiotherapy: Cancer Treatment by …
Increasing the radiosensitivity of cancer cells improves the processes leading to their elimination during radiotherapy and prolonging the survival of cancer patients. In order to enhance the effect of radiotherapy in the treatment of radioresistant neoplasms, radiosensitizers are used.
Development of Novel Radiosensitizers through the National …
Radiation therapy is a mainstay of the curative and palliative treatment of cancer. The addition of radiosensitizing chemotherapy to definitive radiation therapy has been one of the most significant breakthroughs in the treatment of cancer over the past several decades.
Radiosensitizing Agent - an overview | ScienceDirect Topics
A radiosensitizer, or a radiosensitizing agent, is a pharmacologic agent that potentiates the toxicity of radiation therapy. Radiation therapy uses various external energy sources such as X-rays and protons to shrink tumors by disrupting their DNA.

2023年8月14日 · A radiosensitizing dose is a higher dose of radiation given to a patient prior to taking a standard radiation therapy dose. It is used to increase the sensitivity of the tumor cells to radiation treatment, making the cancer more likely to respond to the lower dose radiation therapy.
Boosting the Radiosensitizing and Photothermal Performance of Cu
2019年2月1日 · Herein, we report that dumbbell-shaped heterogeneous copper selenide-gold nanocrystals can serve as an efficient radiosensitizer for enhanced radiotherapy. The mean lethal dose of X-rays to 4T1 tumor cells can be drastically decreased about 40%, that is, decreasing from 1.81 to 1.10 Gy after culture with heterostructures.
Radiosensitizing high-Z metal nanoparticles for enhanced …
Since GBM is a radioresistant malignancy and the most of GBM recurrences occur in the radiotherapy field, increasing the effectiveness of radiotherapy using high-Z metal nanoparticles (NPs) has recently attracted attention.
