BCL2 and renal pelvis/ureter urothelial carcinoma: Jeong et al. analyzed several apoptosis-related markers in 112 consecutive UTUC patients (74), reporting that 27% and 24% of patients had altered expression of bcl-2 and caspase-3, respectively-the latter of which correlated with pathological tumor stage and grade; bcl-2 was not linked to any clinico-pathological parameter.
