Prognostic and predictive values of interim F-18-FDG PET during neoadjuvant chemoradiotherapy for esophageal cancer: a systematic review and meta-analysis
- Purpose To determine the prognostic and predictive value of early metabolic response assessed by a change in standardized uptake value (SUV) on interim F-18-FDG PET in patients with esophageal cancer undergoing neoadjuvant chemoradiotherapy.
Methods PubMed and Embase were searched up until 10 September, 2020, for studies evaluating a change in SUV on interim F-18-FDG PET for predicting a pathologic response, progression-free survival (PFS), or overall survival (OS) in patients with esophageal cancer. The sensitivity and specificity for predicting a pathologic response were pooled using bivariate and hierarchical summary receiver operating characteristic (HSROC) models. Meta-analytic pooled hazard ratios (HRs) and their 95% confidence intervals (CIs) were derived using a random-effects model.
Results A total of 11 studies (695 patients) were included in the meta-analysis. For nine studies assessing predictive accuracy, the pooled sensitivity and specificity of an early metabolic response for predicting a pathologic response were 0.80 (95% CI 0.61-0.91) and 0.54 (95% CI 0.45-0.63), respectively. The area under the HSROC curve was 0.64 (95% CI 0.60-0.68). Across the nine studies assessing prognostic value, an early metabolic response determined by interim PET showed pooled HRs for predicting PFS and OS of 0.44 (95% CI, 0.30-0.63) and 0.42 (95% CI, 0.31-0.56), respectively.
Conclusion Change in SUV on interim F-18-FDG PET had significant prognostic value and moderate predictive value for a pathologic response in esophageal cancer treated with neoadjuvant chemoradiotherapy. Interim F-18-FDG PET may help prognostic stratification and guide treatment planning in oncologic practice.
