What is hyperfractionated radiation?

(HY-per-FRAK-shuh-NAY-ted RAY-dee-AY-shun THAYR-uh-pee) Radiation treatment in which the total dose of radiation is divided into small doses and treatments are given more than once a day. Hyperfractionated radiation therapy is given over the same period of time (days or weeks) as standard radiation therapy.

What is radiotherapy meaning?

Listen to pronunciation. (RAY-dee-oh-THAYR-uh-pee) The use of high-energy radiation from x-rays, gamma rays, neutrons, protons, and other sources to kill cancer cells and shrink tumors.

What does hypofractionated radiation therapy mean?

(HY-poh-FRAK-shuh-NAY-ted RAY-dee-AY-shun THAYR-uh-pee) Radiation treatment in which the total dose of radiation is divided into large doses and treatments are given once a day or less often. Hypofractionated radiation therapy is given over a shorter period of time (fewer days or weeks) than standard radiation therapy.

What is the study of radiotherapy?

Radiotherapy technology is a branch of science which deals with treatmeet of cancerous cells through different radiotherapy techniques. Diferent radiotheraphy courses are available which aim to make students learn all the aspect of the field.

What is Hyperfractionation in radiotherapy?

This technique is the basis of radiotherapeutic techniques, such as hyperfractionation, which seeks to control tumors (with responses similar to the acute response tissues) without damaging the adjacent differentiated tissues.

What is accelerated Hyperfractionated radiotherapy for breast cancer?

Accelerated hyperfractionated radiotherapy for locally advanced breast cancer has been predominantly explored at MD Anderson. In a phase III trial, 72 Gy in 1.2 Gy twice daily fractions (bid) was compared with 60 Gy in 2 Gy fractions once a day (qd). The supraclavicular fossa in both arms was treated once a day to 50 Gy.

What is Accelerated fractionation in radiotherapy?

See Fractionation. Cf Accelerated fractionation. The treatment of a tumor with radiation applied in several small doses several hours apart on the same day instead of in a once-a-day dose.

Is hypofractionation possible with modern radiotherapy techniques for locally advanced NSCLC?

This approach has become more feasible as a result of decreasing radiotherapy volumes, which allow for more conformal radiotherapy delivery and limit the dose delivered to normal tissue. Few studies have evaluated hypofractionation with modern radiotherapy techniques for locally advanced NSCLC.
