Tumor regression grade (TRG)PurposeLocally advanced rectal cancer (LARC) patients achieving ypT3 status following neoadjuvant chemoradiation are considered to have poor response with minimal downstaging. However, residual cancer cell amounts vary in the subserosa/perirectal fat. Tumor regression grading...
A novel tumor staging system incorporating tumor regression grade (TRG) with lymph node status (ypN-category) results in better prognostication than ypTNM stage groups after neoadjuvant therapy for esophageal squamous cell carcinoma. Ann Surg. 2022;276:784. Article PubMed Google Scholar Davies AR,...

Pathologically, there are mainly two kinds of methods to assess the residual cancer: tumor-node-metastasis (TNM) and tumor regression grade (TRG). Although TNM has been widely accepted, it still has some limitations, for it is based on the location rather than the amount of residual tumor. ...

To compare Tumor Volume Reduction Rate (TVRR) measured by MR Volumetry after preoperative chemoradiotherapy (CRT) and pathological Tumor Regression Grade (TRG) in Locally Advanced Rectal Cancer (LARC). Material and methods In total, 20 patients with LARC (cT3-T4) treated with CRT followed by To...
In participants with locally advanced rectal cancer following neoadjuvantchemotherapy, diffusion-weighted imaging (DWI) improved the ability of MRI toidentify potential pathologic complete response, with DWI-modified MR tumorregression grade enabling accurate prediction of a pathologic complete response(area ...
Tumor regression grade (TRG) was quantitated in five grades: TRG 1 (complete regression) showed absence of residual cancer and fibrosis extending through the different layers of the esophageal wall; TRG 2 was characterized by the presence of rare residual cancer cells scattered through the fibrosis...
A Expansion of γδ T cells measured by flow cytometry is compared with tumor regression over time. The red dotted line represents γδ T cell frequency measured in peripheral blood from patient E-013. Tumor measurements from E-013 by CT scan are indicated by the black line. Arrow denotes ...
