Evaluation of Mesorectal Fascia in Mid and Low Anterior Rectal Cancer Using Endorectal Ultrasound Is Feasible and Reliable

2014

Accuracy of MRI in assessing mesorectal fascia and predicting circumferential resection margin decreases in low anterior rectal tumors.The purpose of this work was to evaluate the accuracy of endorectal ultrasound in predicting the pathologic circumferential resection margin in low rectal anterior tumors and to compare it with MRI findings.This was a prospective series comparing the preoperative circumferential resection margin assessed by endorectal ultrasound and MRI with pathologic examination.The study was conducted by a specialized colorectal multidisciplinary team at a tertiary teaching hospital.Between 2002 and 2008, 76 patients with mid to low rectal cancer were preoperatively evalu…

Local staging of rectal carcinoma and assessment of the circumferential resection margin with high-resolution MRI using an integrated parallel acquis…

2005

Purpose To assess the diagnostic accuracy of integrated parallel acquisition technique (iPAT) in local staging of rectal carcinoma in comparison to conventional high-resolution MRI. Materials and Methods A total of 28 patients with a neoplasm of the rectum and 15 control patients underwent MRI of the pelvis. High-resolution images were acquired conventionally and with iPAT using a modified sensitivity encoding (mSENSE). Image quality, signal-to-noise and contrast-to-noise ratios (SNR, CNR), tumor extent, nodal status, and delineation of the circumferential resection margin (CRM) were compared. In 19 patients with a carcinoma, MR findings were correlated with the histopathological diagnosis.…

Pretherapeutic MRI for decision-making regarding selective neoadjuvant radiochemotherapy for rectal carcinoma: interim analysis of a multicentric pro…

2012

Purpose: To study the accuracy of different cutoffs for an involved circumferential resection margin (CRM) compared with T and N categories measured by MRI as basis for selective application of neoadjuvant radiochemotherapy (nRCT) in rectal carcinoma. Materials and Methods: In a prospective multicenter observational study involving 153 primarily operated patients, the preoperative results of MRI with pathohistological findings of resected specimens were compared. Results: For a cutoff of ≤1 mm for involvement of the CRM, the accuracy of preoperative MRI was 90.9% (139/153). The negative predictive value was 98.5% (134/136). The four participating departments did not differ significantly. Fo…

EURECCA colorectal: multidisciplinary management: European consensus conference colon & rectum.

2014

Contains fulltext : 137861.pdf (Publisher’s version ) (Closed access) BACKGROUND: Care for patients with colon and rectal cancer has improved in the last 20years; however considerable variation still exists in cancer management and outcome between European countries. Large variation is also apparent between national guidelines and patterns of cancer care in Europe. Therefore, EURECCA, which is the acronym of European Registration of Cancer Care, is aiming at defining core treatment strategies and developing a European audit structure in order to improve the quality of care for all patients with colon and rectal cancer. In December 2012, the first multidisciplinary consensus conference about…

Rektumkarzinom: Behandeln wir zu häufig neoadjuvant? Vorschläge zu einer selektiveren, MRT-basierten Indikation

2006

The present-day optimised surgery (concept of total mesorectal excision) with quality assurance by standardized pathologic examination, advances in radiotherapy and the possibilities of high-spatial-resolution MR imaging require reconsideration of pros and contras of neoadjuvant therapy and respective data. According to the resulting new proposal neoadjuvant long-course radiochemotherapy is indicated for patients with 1) fixed questionably R0 resectable tumors, 2) mobile tumors with the MRT finding of tumor involving the mesorectal fascia or 1 mm or less from it, 3) low rectal tumors extending below the levator origin and invading beyond the muscularis propria. If a high risk of local recur…
