Radiation Therapy Oncology Group (RTOG) 85-01 trial showed a survival advantage for concomitant chemoradiation (50 Gray [Gy] in 25 fractions) with two concurrent and two adjuvant cycles of cisplatin and fluorouracil (5-FU), compared with radiotherapy alone (64 Gy in 32 fractions), with five-year survival rates of 27% versus 0%. 1 The subsequent

The non-SI unit rad is sometimes also used, predominantly in the USA. During radiation therapy, the cumulative absorption rates through the duration of the treatment are generally high in the area being treated. This radiation absorption may permanently destroy the glands that produce saliva, sweat, and other moisture when the dose exceeds 30 grays (Gy). The result is dry mouth and similar side effects. Se hela listan på news-medical.net Se hela listan på cdc.gov Milligray is a derived metric (SI) measurement unit of absorbed radiation dose of ionizing radiation, e.g. X-rays. The SI prefix milli stands for one thousandths . The milligray is equal to one thousandth of a gray (10 -3 Gy), and the gray is defined as the absorption of one joule of ionizing radiation by one kilogram (1 J/kg) of matter, e.g.

For curative cases, the typical dose for a solid epithelial tumor ranges from 60 to 80 Gy, while lymphomas are treated with 20 to 40 Gy. A short-course RT regimen of 25 Gy in 5 fractions is an acceptable treatment option for patients aged ≥65 years, mainly those with a poor performance status or contraindication to chemotherapy, which would be indicated in cases of methylated O6 methylguanine-DNA-methyltransferase promoter tumors. The required conditions for Acute Radiation Syndrome (ARS) are: The radiation dose must be large (i.e., greater than 0.7 Gray (Gy) 1, 2 or 70 rads). Mild symptoms may be observed with doses as low as 0.3 Gy or 30 rads. The dose usually must be external ( i.e., the source of radiation is outside of the patient’s body). The amount of radiation used in photon radiation therapy is measured in grays (Gy), and varies depending on the type and stage of cancer being treated. For curative cases, the typical dose for a solid epithelial tumor ranges from 60 to 80 Gy, while lymphomas are treated with 20 to 40 Gy. Absorbed dose is defined as the amount of energy deposited by ionizing radiation in a substance.
