Summary

This study looked at 60 people with diffuse large B-cell lymphoma who were starting standard chemotherapy (R-CHOP). Researchers used advanced single-cell technology to analyze tumor and blood samples over two years. The goal was to find biomarkers that could help predict how well treatment works and track disease changes.
