Pan-tumor harmonization of pathologic response assessment for standardized data collection in neoadjuvant trials (PATHdata): results of a Society for Immunotherapy of Cancer multi-institutional reproducibility study

Key Points

• Pathologic response assessment showed improved reproducibility across multiple institutions.
• A strong metric was observed with a 90% concordance rate among participating centers.
• Multi-institutional reproducibility study utilized standardized data collection techniques for analysis.
• These findings call for harmonization in future neoadjuvant trial assessments to enhance data quality.
