Comments
Guide for use:
A total dose of radiation is delivered to the patient in a number of even parts or treatment sessions (fractions). Although a treatment session may include several treatment portals delivered within a confined period of time, usually a few minutes, it is still considered one fraction.
Record the number of fractions of radiotherapy treatment for all courses delivered to the patient during the course of treatment for cancer.
The patient may receive more than one course of radiotherapy during the course of treatment. For example, radiotherapy may be administered to the primary site and the site of a distant metastasis. Record the total radiation dose for each course of treatment.
The number of fractions administered is recorded regardless of whether the course of treatment is completed as intended and regardless of the intent or timing of treatment.
The number of radiotherapy fractions recorded should include any boost.
Brachytherapy (or implants) may be delivered more than once, each treatment is recorded as a fraction.
Do not include treatment with unsealed radioisotopes.Origin:

Comments:
The collection of specific treatment information is useful to evaluate patterns of care, the effectiveness of different treatment modalities, and treatment by patient outcome.
