Description: 
Records the total number of treatment sessions (fractions) administered during the first course of treatment.
Registry Coding Instructions: 

·         The number of treatments or fractions will typically be found in the radiation oncologist’s summary letter for the first course of treatment. Determination of the exact number of treatments or fractions delivered to the patient may require assistance from the radiation oncologist for consistent coding.
 
·         Although a treatment session may include several treatment portals delivered within a relatively confined period of time—usually a few minutes—it is still considered one session.
 
·         The total number of treatment sessions (fractions) is the sum of the number of fractions of regional treatment and the number of fractions of boost treatment.
·         Count brachytherapy or implants as a single treatment or fraction.
 

Analytic Note: 

This item is reported as an optional item per the ROADS manual for cases diagnosed between January 1, 1996 and December 31, 2002, and required thereafter.
