Guide for use:
Record the first or earliest date radiotherapy commenced for all courses of radiotherapy administered during the initial course of treatment. The initial course of treatment includes all treatments administered to the patient from diagnosis and before disease progression or recurrence.
The patient may receive more than one course of radiotherapy during the initial course of treatment. For example, in the treatment of cancer, radiotherapy may be administered to the primary site and the site of a distant metastasis. Record the start date for each course of treatment.
The start date of radiotherapy is recorded regardless of whether the course of treatment is completed as intended, and regardless of the intent or timing of treatment.
Record the start date for radiotherapy administered as external beam radiotherapy or brachytherapy. Do not include radiotherapy with unsealed radioisotopes.
This item should be used when collecting information about cancer patient care for safety and quality monitoring and other public health purposes.
