All patients received dynamic contrast-enhanced MRI (DCE-MRI) pretreatment, after 2 cycles, 4 cycles, and after completion of treatment. The percentage change in tumor WIS from that before treatment (ΔWIS) was measured at each time point. Predictive performance for pCR was assessed by using the area under the receiver operating characteristic curve (AUC) for the overall cohort and across molecular subtypes.<h4>Results</h4>A total of 162 patients were included in this study (mean age, 51.9 years ± 9.1 [SD]), and 43 (26.5%) achieved pCR. Overall, ΔWIS demonstrated comparable performance in predicting pCR after 2 cycles (AUC, 0.82; 95% CI: 0.73, 0.91), 4 cycles (AUC, 0.86; 95% CI: 0.78, 0.93), and after completion of NAC (AUC, 0.87; 95% CI: 0.8, 0.93), with no significant differences observed (all p > 0.05). Utilizing optimal threshold values of -33%, -44%, and -59% at each time point, ΔWIS yielded sensitivities ranging from 74.4% to 86.0% and specificities ranging from 75.6% to 80.7%. In molecular subtype analysis, ΔWIS after 4 cycles exhibited excellent predictive performance for pCR in triple-negative breast cancers (AUC, 0.96; 95% CI: 0.9, 1), outperforming its performance in Luminal B tumors (AUC, 0.83; 95% CI: 0.71, 0.94; p = 0.04).<h4>Conclusion</h4>Tumor WIS changes from DCE-MRI could dynamically monitor neoadjuvant chemotherapy (NAC).<h4>Key points</h4>Question Currently, there is no widely accepted standard imaging biomarker for predicting pCR in breast cancer patients undergoing NAC. Findings WIS changes outperformed tumor size in predicting pCR at four time points during NAC, and showed comparable predictive performance across all time points. Clinical relevance Longitudinal changes in the WIS derived from dynamic contrast-enhanced MRI enable real-time prediction of pathologic response to NAC in patients with breast cancer, supporting personalized treatment monitoring and decision-making.","is_dataset_classified":null,"base_score":0.6931471805599453,"endowment":0.6931471805599453,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"41042372","pmcid":null,"openalex_id":"https://openalex.org/W4414778038","authors":[],"funders":[{"funder_name":"National Natural Science Foundation of China","grant_id":"82172025","title":null},{"funder_name":"National Natural Science Foundation of China","grant_id":"82302302","title":null},{"funder_name":"Science & Technology Development Fund of Tianjin Education Commission for Higher Education","grant_id":"2024KJ189","title":null},{"funder_name":"Tianjin Key Medical Discipline (Specialty) Construction Project","grant_id":"TJYXZDXK-009A","title":null}],"total_grants":4,"fwci":0.7026,"citation_percentile":0.73114478,"influential_citations":0,"citation_trend":[{"year":2025,"count":1}],"oa_status":"closed","license":"https://www.springernature.com/gp/researchers/text-and-data-mining","oa_locations":[{"url":"https://link.springer.com/content/pdf/10.1007/s00330-025-12042-w.pdf","host_type":"publisher"},{"url":"https://link.springer.com/article/10.1007/s00330-025-12042-w","host_type":"publisher"},{"url":"https://doi.org/10.1007/s00330-025-12042-w","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/41042372","host_type":"repository"}],"fields_of_study":["MRI in cancer diagnosis","Breast Cancer Treatment Studies","Lanthanide and Transition Metal Complexes"],"mesh_terms":["Adult","Breast Neoplasms","Contrast Media","Female","Humans","Image Enhancement","Magnetic Resonance Imaging","Middle Aged","Predictive Value of Tests","Retrospective Studies","Treatment Outcome","Chemotherapy, Adjuvant","Neoadjuvant Therapy"],"keywords":["Breast cancer","Neuroradiology","Breast MRI","Dynamic contrast","Chemotherapy","Dynamic contrast-enhanced MRI","Interventional radiology","Biomarker","Neoadjuvant therapy","Magnetic Resonance Imaging","Neoadjuvant chemotherapy","Pathologic Complete Response","Dynamic Contrast Enhancement"],"sdg_mappings":[],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-01T21:42:44.486152Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
