abstract = {Muscle-invasive bladder cancer (MIBC) is a biologically
heterogeneous disease with variable prognosis after radical
cystectomy. While conventional clinicopathological
parameters offer limited prognostic value, growing evidence
highlights the role of the tumor immune microenvironment
(TIME)-including immune cell composition and spatial
architecture-as robust biomarkers for disease progression
and outcomes.The study included 251 consecutive patients
with MIBC who underwent cystectomy (2004-2014, LMU Munich).
Three 1-mm-diameter cores were sampled from the tumor
invasive front and center in the cystectomy specimen. Six
immune checkpoint proteins (ICPs; IDO, PD-L1, PD-1, LAG-3,
TIM-3, and VISTA) were quantified digitally following
immunohistochemical (IHC) staining. ICP-positive immune and
tumor cells were stratified and densities were
hierarchically clustered. Multivariable Cox models were then
used to assess the association with overall (OS) and
disease-free survival. The minimum tumor sample count needed
to detect the maximum ICP expression per patient was
estimated via a 1000-fold bootstrap resampling
simulation.IDO+ and VISTA+ immune cells dominated the TIME,
while PD-L1+ tumor cells exhibited a dichotomous expression
pattern. Analysis of three spatially distinct cores was
sufficient to recover maximal expression of low-abundance
TIM-3+ and VISTA+ immune cells, while four cores were
required for all other markers. ICP-based clustering
revealed three TIME subtypes (CID1-3), of which CID3 was
associated with markedly worse prognosis (median OS 18.5 vs
100.5 mo; p = 0.0007). This classification outperformed
Union for International Cancer Control staging and improved
patient stratification in late-stage MIBC.A six-marker,
multiregional ICP panel delivers a robust,
stage-independent, actionable risk stratification in MIBC.
At least four biopsies are advised for routine immune
profiling; further longitudinal external validation is
warranted.},
