Molecular subtypes and quantitative analysis of PD-L1 and tumor-associated immune cells in uterine carcinosarcoma.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveIn the present study, molecular subtypes were determined, programmed death-ligand 1 (PD-L1) and tumor-associated immune cells (TAICs) were quantitatively detected, and their effect on prognosis in uterine carcinosarcoma (UCS) was analyzed.
methodsThe study included 65 UCS cases. Direct sequencing of POLE exonuclease domain and immunohistochemistry of mismatch repair (MMR) deficiency proteins and p53 were used to stratify molecular subtypes. QuPath was used for quantitative immunohistochemical detection of PD-L1 and TAICs. The chi square test was used to determine the association between molecular subtypes and expression of PD-L1 and TAICs. The Kaplan-Meier method and Cox proportional hazards regression were used for plotting and survival analysis.
resultsIn 65 UCS cases, 1 case (1.5%) was POLE ultramutated (POLEmut) subtype, 11 cases (16.9%) were deficient MMR (dMMR) subtype, 32 cases (49.3%) were p53 mutant (p53mut) subtype, and 21 cases (32.3%) were nonspecific molecular profile (NSMP) subtype. The positive density of PD-L1 in tumor (p=0.022), CD8 in stroma (p=0.036), and CD163 in stroma (p=0.025) were significantly associated with molecular subtypes. The patients with POLEmut and dMMR subtypes had a relatively better prognosis trend than patients with NSMP and p53mut subtypes. The patients with high positive density of PD-L1 in tumor had significantly better prognosis; however, high positive density of CD163 in stroma showed significantly worse prognosis.
conclusionUCS could be classified into four molecular subtypes associated with prognosis. PD-L1 and M2 macrophages could effectively predict the prognosis of patients with UCS.
