The 2 coprimary outcomes were a composite of death or heart failure (HF) hospitalization and a composite of myocardial infarction (MI) or late revascularization. Multivariable Andersen-Gill Cox models with robust variance estimators were used to incorporate recurrent events. Outcomes were modeled as a smooth function of MBF_stress and MBF_rest, with restricted cubic splines to allow nonlinearity. <b>Results:</b> The analysis included 8,131 consecutive patients (median age of 68 y; 46.1% were women; median follow-up of 520 d (interquartile range, 186-921 d), among whom 471 deaths, 828 HF hospitalizations, 164 MIs, and 429 late revascularizations occurred. After adjusting for the relevant covariates, an MFR of 2 achieved through a lower MBF_rest was associated with a significantly lower incidence of death and HF hospitalization, whereas an MFR of 2 achieved through a greater MBF_stress was associated with a significantly lower incidence of MI and late revascularization. Assessments of the partial χ² statistic, which measures the importance of predictors, similarly confirmed that MBF_rest was more important for predicting death or HF hospitalization whereas MBF_stress was more important for predicting MI or late revascularization. <b>Conclusion:</b> Measurements of absolute myocardial blood flow offer complementary prognostic value to MFR. A diminished MBF_stress may signal a greater risk of future ischemic outcomes, whereas an elevated MBF_rest may signal a greater risk of future death or HF hospitalization.</p>","PeriodicalId":94099,"journal":{"name":"Journal of nuclear medicine : official publication, Society of Nuclear Medicine","volume":" ","pages":"1406-1411"},"PeriodicalIF":9.1,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144328199","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to evaluate and compare their prognostic impact. <b>Methods:</b> This retrospective study analyzed 604 patients with localized ESCC who received induction chemotherapy followed by chemoradiotherapy, with or without surgery, at Asan Medical Center between 2006 and 2018. Metabolic responses after induction chemotherapy (before chemoradiotherapy) and after chemoradiotherapy were evaluated using European Organisation for Research and Treatment of Cancer-based criteria adapted for prognostic assessment. <b>Results:</b> In patients treated with definitive chemoradiotherapy (bimodality therapy), metabolic response after both induction chemotherapy and chemoradiotherapy was significantly associated with progression-free survival (PFS) and overall survival (OS). Complete metabolic response after induction chemotherapy correlated with the longest survival (PFS, 58.9 mo; OS, 90.8 mo), whereas progressive metabolic disease predicted poor prognosis (PFS, 3.7 mo; OS, 7.0 mo; <i>P</i> < 0.001). A similar pattern was observed for postchemoradiotherapy metabolic response. In patients who underwent surgery (trimodality therapy), metabolic response after induction chemotherapy did not significantly impact survival. However, in patients for whom surgery was initially planned, it remained prognostic, suggesting its prognostic relevance in the preoperative setting. Postchemoradiotherapy metabolic response was a strong independent prognostic factor in both bimodality therapy and trimodal therapy. Patients with diffuse esophagitis after chemoradiotherapy had intermediate survival outcomes, among complete metabolic response and partial metabolic response groups, indicating a distinct prognostic pattern. <b>Conclusion:</b> Postchemoradiotherapy metabolic response is a strong prognostic marker in localized ESCC, supporting its use for risk stratification. Early metabolic response after induction chemotherapy may also inform treatment decisions, particularly in surgery-intended patients.</p>","PeriodicalId":94099,"journal":{"name":"Journal of nuclear medicine : official publication, Society of Nuclear Medicine","volume":" ","pages":"1352-1364"},"PeriodicalIF":9.1,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144562476","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
