Implication

Analyses identify circulating T cell profiles and tumor microenvironment types linked to immune checkpoint blockade outcomes in sarcoma, suggesting personalized treatment strategies.

Key Points

To identify biomarkers associated with response and resistance to immune checkpoint blockade in sarcoma patients.
Analyzed peripheral blood and tumor samples from sarcoma patients in clinical trials.
Used flow cytometry to define T cell immunotypes in circulating blood samples.
Employed RNA sequencing to classify tumor microenvironment subtypes.
Applied deep learning to analyze tumor slides for lymphoid aggregates.
Proliferative circulating T cell immunotype linked to worse overall survival.
Immune-enriched/non-fibrotic tumor microenvironment subtype associated with better response and survival outcomes.
Automated analysis detected lymphoid aggregates in tumors, aiding in identifying immune-enriched profiles.
