In a cross-continental benchmark, breast tumor segmentation generalized reasonably across institutions, but predicting pathologic complete response from pre-treatment DCE-MRI alone was no better than random for nearly all teams.
Multicenter breast DCE-MRI data and segmentations from patients in the I-SPY 1/ACRIN 6657 trials,

The MAMA-MIA Challenge: Advancing Generalizability and Fairness in Breast MRI Tumor Segmentation and Treatment Response Prediction
In a cross-continental benchmark, breast tumor segmentation generalized reasonably across institutions, but predicting pathologic complete response from pre-treatment DCE-MRI alone was no better than random for nearly all teams.
