Description
Records the dominant modality of radiation therapy used to deliver the most clinically significant boost dose to the primary volume of interest during the first course of treatment. This is accomplished with external beam fields of reduced size (relative to the regional treatment fields), implants, stereotactic radiosurgery, conformal therapy, or intensity-modulated radiation therapy. External beam boosts may consist of two or more successive phases with progressively smaller fields, and they are generally coded as a single entity. This field is used with Rad--Regional RX Modality [1570].
Rationale
Radiation treatment frequently is delivered in two or more phases that can be summarized as regional and boost treatments. A boost dose is administered to a volume within the regional volume. For outcomes analysis, the modalities used for each of these phases can be very important
