Baseline 18F-FDG PET/CT-derived heterogeneity index predicts poor pathological response after neoadjuvant chemoradiotherapy in locally advanced rectal cancer.

Comparison of metabolic variables in FDG PET/CT in rectal cancer patients who achieved a complete or incomplete response following neoadjuvant chemoradiotherapy.

18F-FDG PET/CT metabolic parameter to predict pathological complete response and survival after neoadjuvant immunotherapy plus chemoradiotherapy in resectable esophageal squamous cell carcinoma

Evaluating the diagnostic efficacy of 18F-FDG PET/CT for achieving pCR after nICRT for ESCC and its prognostic value for survival showed that patients with poorer OS and DFS had poorer prognostic factors for OS and DFS, but LnSUVmax2 has diagnostic value for lymph nodes metastasis.

18F-FDG PET/CT radiomics across treatment timepoints for predicting response to neoadjuvant therapy in locally advanced esophageal cancer: a systematic review and meta-analysis

Pathological complete response (pCR) after neoadjuvant therapy is achieved in only about 20%–40% of patients with locally advanced esophageal cancer (LAEC), yet it is the strongest determinant of long-term survival. 18 F-fluorodeoxyglucose ( 18 F-FDG) positron emission tomography/computed tomography (PET/CT)...

Association of PET/CT-Derived Metabolic Parameters with Pathological Complete Response After Neoadjuvant Systemic Therapy in Breast Cancer: An Analysis Across Molecular Subtypes

Background: Pathological complete response (pCR) following neoadjuvant systemic therapy (NST) is associated with improved outcomes in breast cancer. We evaluated the association between PET/CT-derived metabolic parameters and pCR and explored whether these associations differed according to molecular subtype. Methods:...

Comparison between 18 F-FDG PET/MRI and CT for distant metastases detection in restaging of locally advanced rectal cancer after neoadjuvant chemoradiotherapy

To evaluate the diagnostic accuracy of total-body 18 F-FDG PET/MRI compared with contrast-enhanced CT in detecting distant metastases in patients with locally advanced rectal cancer (LARC) after neoadjuvant chemoradiotherapy (pCRT). This retrospective study included patients with LARC treated with pCRT bet...

Integrated model of MRI biomarkers and clinical factors for predicting pathologic response after neoadjuvant chemoradiotherapy in locally advanced rectal cancer.
