Preoperative Evaluation of Lower Rectal Cancer by Pelvic MR with and without Gel Filling

چکیده
Patients with rectal cancer in the lower third of the rectum have three main options for surgical treatment including transanal resection, abdominoperineal resection (APR), total mesorectal excision (TME) and preoperative concurrent chemoradiotherapy (CCRT) with surgical management. However, APR can lead to a decreased quality of life, viewed in colostomy and compared to other surgical treatments. To achieve an acceptable quality of life, sphincter-saving procedures have become increasingly popular (1, 2). In recent years, high-resolution pelvic magnetic resonance imaging (MRI) has achieved an essential role in the determination of circumferential resection margin (CRM) and the evaluation of sphincter invasion. The prediction of sphincter involvement and measurement of the distance from the anal verge are important for treatment planning in patients with lower rectal cancer INTRODUCTION

MR imaging for preoperative evaluation of primary rectal cancer: practical considerations.
High-resolution magnetic resonance (MR) imaging plays a pivotal role in the pretreatment assessment of primary rectal cancer. The success of this technique depends on obtaining good-quality high-resolution T2-weighted images of the primary tumor; the mesorectal fascia, peritoneal reflection, and other pelvic viscera; and superior rectal and pelvic sidewall lymph nodes. Although orthogonal axial...

Rectal cancer is a common malignancy that continues to have a highly variable outcome, with local pelvic recurrence after surgical resection usually leading to incurable disease. The success of tumor excision depends largely upon accurate tumor staging and appropriate surgical technique, although the results of recent surgical trials indicate that evaluation of the involvement of the mesorectal...

OBJECTIVE To investigate the accuracy of preoperative computed tomography (CT), magnetic resonance (MR) imaging and diffusion-weighted imaging with background body signal suppression (DWIBS) in the prediction of nodal involvement in primary rectal carcinoma patients in the absence of tumor invasion into pelvic structures.

Preoperative chemoradiotherapy (CRT) and lateral pelvic lymph node (LPLN) dissection (LPLD) based on pretreatment imaging are performed to improve oncological outcomes at our institution. However, the advantage of LPLD following preoperative CRT in advanced rectal cancer remains unclear. The objective of the present study was to assess the validity of this approach. Thirty-two patients with adv...

BACKGROUND We retrospectively reviewed magnetic resonance (MR) images of 96 patients with diagnosis of rectal cancer to evaluate tumour stage (T stage), involvement of mesorectal fascia (MRF), and nodal metastasis (N stage).Our gold standard was histopathology. METHODS All studies were performed with 1.5-T MR system (Symphony; Siemens Medical System, Erlangen, Germany) by using a phased-array...
