BCAN 2019: Radiographic Consideration Prior to Clinical Trial Enrollment

Washington, DC (UroToday.com) Jamie Marko from the NIH Clinical Center, Bethesda, MD discussed radiographic consideration prior to clinical trial enrollment. All pre-trial enrollment imaging for bladder cancer should be <4 wks prior to enrollment. Generally, >1cm cut-off for defining malignancy accepted. Always archive prior exams to refer if needed for unequivocal lesions. Defining progression should be used from RECIST criteria >1cm for new lesion, <1cm demonstrate >50% growth on 2 consecutive exams with >5mm absolute increase or if <1cm >50% growth on a single exam or if multifocal sites are considered a recurrent disease. Define the date of recurrence/progression when definition met and do NOT backdate. Together, all of these standards will help clinical trial enrollment and coalesce accurate radiographic endpoints to compare data.
