Second Opinion Expert Pathology Review in Bladder Cancer: Implications for Patient Care

Objectives. To review bladder specimens referred to our facility for secondary review to determine the frequency and degree of changes in pathological diagnoses, which could affect patient care. Methods. A retrospective review of 246 bladder specimens sent to our pathology department for second opinion pathological review was performed.
