Notes:
*"Percent area involved" may seem like an odd thing to request 'cause it is sampling dependent, i.e. if the radiologist sticks the biopsy needle deeper into the lesion more of the core is positive, but urologists think it is important -- more important than perineural invasion.<ref>{{cite journal |author=Rubin MA, Bismar TA, Curtis S, Montie JE |title=Prostate needle biopsy reporting: how are the surgical members of the Society of Urologic Oncology using pathology reports to guide treatment of prostate cancer patients? |journal=Am.
