Comments
Guide for use:
The target site is collected for all courses of radiotherapy administered to the patient 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 target site for radiotherapy is recorded regardless of whether the course of treatment is completed as intended, the intent or timing of the radiotherapy, and the radiation therapy treatment modality.
Record the value representing all the sites targeted for radiotherapy during the initial course of treatment. There may be more than one site targeted for treatment. For example, the primary tumour site and the site of a distant metastasis may receive radiotherapy as part of the initial course of treatment. In this case code "5" would be recorded.
The target site for surgery is collected as a separate data item.
Comments:This is collected to identify which sites are targeted by radiotherapy and is useful in evaluating patterns of care and patient outcomes.
