CV1-secreting sCAR-T cells potentiate the abscopal effect of microwave ablation in heterogeneous tumors.

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
Microwave ablation (MWA) triggers a weak systemic immune response that leads to the abscopal regression of distant metastases while killing local tumors, known as the abscopal effect. Combining MWA with chimeric antigen receptor (CAR)-T cells demonstrates promise in enhancing the abscopal effect in antigen-homogeneous tumors. However, the loss of the antigen recognized by CAR or intrinsic antigenic heterogeneity in solid tumors poses a major obstacle. SIRPα variant (CV1)-secreting CAR-T (sCAR-T) cells elicit an abscopal effect on distant tumors with antigen heterogeneity in mice receiving local MWA. Mechanistically, sCAR-T cells can locally eliminate antigen-positive tumors and secrete CV1, whereas the secreted CV1 can activate macrophages that migrate to non-ablated tumor sites in response to post-MWA chemokines, eliciting a macrophage-dependent abscopal effect that enables phagocytosis of antigen-heterogeneous cancer cells. This macrophage-dependent abscopal effect instigated by MWA and sCAR-T cells offers a clinically translatable strategy in metastatic solid tumors with antigen heterogeneity.
