Immunologic correlates in a CIC::DUX4 fusion-positive sarcoma responsive to dual immune checkpoint blockade.

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
cic:DUX4 sarcoma (CDS) is a rare and aggressive subtype of soft tissue sarcoma with poor prognosis and limited treatment options. Immunotherapy has not been studied in this disease. To our knowledge, response to immune checkpoint blockade (ICB) has not been previously reported. Here, we present the first case of a patient with CDS responding to dual ICB with nivolumab and relatlimab. Immunohistochemical (IHC) analysis of pre-treatment samples revealed minimal immune cell infiltration, with scarce CD3+, CD8+, and FOXP3+ T-cells and negligible expression of PD-L1 and PD-1 markers. Post-treatment tumor samples revealed a significant shift in the immune microenvironment, with increased CD8 + T-cell infiltration and co-expression of exhaustion markers PD-1 and LAG-3 following treatment. These findings suggest that doublet ICB can activate an antitumor immune response in CDS, overcoming the immune cold phenotype typically associated with this sarcoma. This case provides the first evidence of dual PD-1/LAG-3 blockade inducing an immune response in CDS. The favorable response and tolerability observed in this patient highlight the potential of dual ICB as a therapeutic option in CDS that merits further investigation.
