High-resolution rectal MRI plays a crucial role in evaluating rectal cancer by providing multiple prognostic findings and imaging features that guide proper patient management. Quality reporting is critical for accurate effective communication of the information among multiple disciplines, for which a systematic structured approach is beneficial. Existing guides on reporting of rectal MRI are d...

Background. Here we present a concise review on the evaluation and management of locally recurrent rectal cancer, which despite marked reductions in the rate of recurrent rectal cancer remains an important problem. Methods. This educational review discusses the diagnosis, evaluation, and management of recurrent rectal cancer. Results. Despite improvements in both the neoadjuvant and surgical ma...

Standard treatment for stage II and III rectal cancer has long consisted of neoadjuvant long-course chemoradiotherapy (CRT) or short-course radiotherapy (SCRT) followed by total mesorectal excision...

Controversy remains regarding whether preoperative chemoradiation protocol should be applied uniformly to all rectal cancer patients regardless of tumor height. This pooled analysis was designed to evaluate whether preoperative chemoradiation can be safely omitted in higher rectal cancer.An international consortium of 7 institutions was established. A review of the database that was collected f...

Livin is a novel member of the inhibitor of apoptosis protein family, which has been identified to be expressed in various malignancies and is suggested to be associated with poor prognostic significance. However, no data are available concerning the significance of livin in mid-distal rectal cancer. In the present study, livin expression, and its association with clinicopathological characteri...

Introduction: Rectal cancer is a heterozygous disease in which cancerous cells grow in the rectum and lower parts of the colon. The primary cause of this cancer is not yet known, but factors such as over age 50, smoking, family history, improper diet or having a history of polyps and inflammatory bowel disease are the major risk factors for developing the rectum cancer. The rec...

Some clinical trials demonstrated local resection for clinical T1 rectal cancer was safe and effective. But for clinical T2 rectal cancer, the results were controversial. Neoadjuvant therapy (NT) is proven to reduce the opportunity of advanced rectal cancer recurrence in various researches. The objective of this Meta-Analysis was to evaluate the oncological outcomes of transanal endoscopic micr...

OBJECTIVE To determine whether quantitative perfusion parameters of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) correlate with immunohistochemical markers of angiogenesis in rectal cancer. MATERIALS AND METHODS Preoperative DCE-MRI was performed in 63 patients with rectal adenocarcinoma. Transendothelial volume transfer (K(trans) ) and fractional volume of the extravascular...

Background: In intracavitary brachytherapy for gynecological cancers, various techniques are used to locate the anterior rectal wall nearest to the sources but there is no consensus on the best method to do so. This study aimed to compare a technique used routinely in some centers that employs a wire marker to locate the position of the maximum rectal dose point, versus the method recommended b...

A case-control study of colorectal cancer in relation to dietary, smoking, and drinking habits was undertaken in Saitama Prefecture, Japan. The study was based on 181 newly diagnosed cases of adenocarcinoma of the colorectum at a single institution and 653 general population controls. Dietary habits were investigated on the basis of the intake of 12 foods and 12 food groups in a food intake fre...
