JO - Cancers VL - 15 IS - 12 SN - 2072-6694 CY - Basel PB - MDPI M1 - DKFZ-2023-01295 SP - 3209 PY - 2023 AB - LARC is managed by multimodal treatments whose intensity can be highly modulated. In this context, we need surrogate endpoints to help predict long-term outcomes and better personalize treatments. A previous study identified 2yDFS as a stronger predictor of OS than pCR in LARC patients undergoing neoadjuvant RT. The aim of this pooled analysis was to assess the role of pCR and 2yDFS as surrogate endpoints for OS in a larger cohort. The pooled and subgroup analyses were performed on large rectal cancer randomized trial cohorts who received long-course RT. Our analysis focused on the evaluation of OS in relation to the pCR and 2-year disease status. A total of 4600 patients were analyzed. Four groups were identified according to intermediate outcomes: 12 KW - disease-free survival (Other) KW - intermediate endpoints (Other) KW - new risk-based classification (Other) KW - pathological complete response (Other) KW - personalized treatment (Other) KW - rectal cancer (Other) LB - PUB:(DE-HGF)16 C6 - pmid:37370819 DO - DOI:10.3390/cancers15123209 UR - https://inrepo02.dkfz.de/record/277133 ER -
