Tumor Burden Linked to Worse Survival in Rare Cancers Treated with Immunotherapy

Mar 30, 2026

A secondary analysis of the Southwest Oncology Group S1609 trial found that larger baseline tumor burden correlated with shorter overall survival but not progression-free survival in rare cancer patients treated with nivolumab plus ipilimumab. The study of 722 patients showed tumor burden was independently associated with survival outcomes but not predictive of tumor regression after dual immunotherapy.
