When a direct lesion measurement TEST is selected on the report option or detected by the report processing (such as
LDIAM, or
DIAMETER or a variation of this test), the measurements (as recorded in
TRSTRESN) are summed across (Target) lesion values at a given time unit.
Select Study Visit to use
VISIT/
VISITNUM and potentially Time Point (
TRTPT if detected) for defining groups of lesions that should be aggregated to create a measurement for tumor burden.
Select Study Day to sum lesions based on the date of the test (transformed into days relative to study start).
