For example, if a patient had radiotherapy to a limb and also to the lungs for a Ewing?s sarcoma these should be entered in one episode of treatment but as separate radiotherapy courses with their respective site, total dose, and number of fractions. They will both be within one episode
Short | Identifier of the radotherapy episode

56. Radiotherapy.target.site
Definition | RT sites are coded with a 3 tier level (see list). The first is ?Tier 1?. The first digit/s of the code, describes the large topographical body areas e.g. brain, chest, abdomen, limb. Since radiation fields often involve more than one topographical area we have added ?cervico-thoracic?, ?thoraco abdominal? and ?abdomino pelvic? areas to Tier 1. The second (Tier 2) includes subcategories of Tier 1 sites e.g. brain stem, heart, liver, upper limb. Where the information is available a third (Tier 3) of further subdivisions includes more detailed areas. When using the SurPass platform, as you start typing the name of the site, a drop down list with related terms will appear (special sites like Inverted Y are included). If the RT site listed in the medical record cannot reasonably be matched to one of the sites listed in the computer, choose ??Other' (.98 in tier 2) and then add in free text the name of this RT site.

Definition | RT sites are coded with a 3 tier level (see list). The first is ?Tier 1?. The first digit/s of the code, describes the large topographical body areas e.g. brain, chest, abdomen, limb. Since radiation fields often involve more than one topographical area we have added ?cervico-thoracic?, ?thoraco abdominal? and ?abdomino pelvic? areas to Tier 1. The second (Tier 2) includes subcategories of Tier 1 sites e.g. brain stem, heart, liver, upper limb. Where the information is available a third (Tier 3) of further subdivisions includes more detailed areas. When using the SurPass platform, as you start typing the name of the site, a drop down list with related terms will appear (special sites like Inverted Y are included). If the RT site listed in the medical record cannot reasonably be matched to one of the sites listed in the computer, choose ??Other' (.98 in tier 2) and then add in free text the name of this RT site.
