This study aimed to explore the prognostic impact of lymph node regression grade (LRG) in patients with locally advanced rectal cancer (LARC) following NCRT and radical surgery and develop a predictive nomogram for disease-free survival (DFS).MethodsLARC patients undergoing NCRT and radical surgery between 2013 and 2014 were enrolled and divided into LRG low ( ≤ 2), middle (3–9), and high (≥ 10) groups. Clinicopathological characteristics and survival outcomes were compared. Predictors for DFS were identified by Cox regression analysis, and a nomogram was constructed.ResultsA total of 257 LAR...

In this study, we performed a gene expression study using formalin-fixed paraffin-embedded (FFPE) tumor biopsy samples from 156 LARC patients (training cohort n = 60; validation cohort n = 96); we identified the nine-gene signature (FGFR3, GNA11, H3F3A, IL12A, IL1R1, IL2RB, NKD1, SGK2, and SPRY2) that distinctively differentiated responders from non-responders in the training cohort (accuracy = 86.9%, specificity = 84.8%, sensitivity = 81.5%) as well as in an independent validation cohort (accuracy = 81.0%, specificity = 79.4%, sensitivity = 82.3%). The signature was independent of all pathological and clinical features an...

Authors: Votava J, Kachlik D, Hoch J Abstract Total mesorectal excision (TME) was first described 40 years ago by Richard Heald. The purpose of this article is to point out importance of this surgical procedure. Starting from first attempts to surgically cure rectal carcinoma in the 19th century through Miles' operation at the beginning of the 20th century results were not satisfactory due to high number of local recurrences after resections for rectal cancer. Progress in surgical technique and knowledge of anatomy and embryology of the rectum led to development of TME. Principle of TME is surprisingly simple: remo...

DR DANIEL ALBO (Augusta, GA): There is a significant shift in the presentation of colorectal cancer in population-based studies. Currently, 3 of 10 rectal cancers are actually diagnosed before the age of 50 years. I noticed that you focused your study on colon cancer patients. Did you notice a significant number of these patients who present with rectal disease as a primary site, in particular, the carcinomatosis data set? Those are known to have an even more aggressive prognostic factor of outcomes.

ConclusionsAL may negatively impact cancer-specific outcomes after curative rectal cancer surgery and could be considered an independent negative prognostic factor.
