" Early descriptions of UTUC in LS were limited by small patient numbers, lack of pathological confirmation, placement in the broad categories of genitourinary malignancy (together with bladder or renal cell carcinomas) or kidney malignancy (without distinguishing renal pelvis or renal cell carcinoma) and no available molecular or genetic testing. Not until the later introduction of the Amsterdam Criteria II20 and the Bethesda Criteria21 did patients with extracolonic malignancies receive full consideration for study inclusion."
