Which data element describes the initial therapy provided to patients in NCDB?

• A. Type of first-course treatment administered
• B. Disease recurrence
• C. Survival information
• D. Tumor staging

Answer: (A)

This item tests identifying which NCDB data element records the initial therapy given to a patient. In the NCDB, the first-course treatment is documented as the type of initial treatment administered, capturing what was done first after diagnosis—such as surgery, chemotherapy, radiation, or a combination of these. This distinguishes initial therapy from other data fields that track later events or disease characteristics. Disease recurrence describes whether cancer returned after treatment, not the initial treatment itself. Survival information reflects patient outcomes over time, not the therapy given. Tumor staging notes how extensive the disease is at diagnosis, not what treatment was chosen first. Therefore, the element describing the initial therapy provided to patients is the type of first-course treatment administered.
