متن کاملPreoperative staging of rectal cancer.
Detailed preoperative staging using high resolution magnetic resonance imaging (MRI) enables the selection of patients that require preoperative therapy for tumour regression. This information can be used to instigate neoadjuvant therapy in those patients with poor prognostic features prior to disturbing the tumour bed and potentially disseminating disease. The design of trials incorporating MR...
متن کاملPreoperative imaging staging of rectal cancer.
Carcinomas of the rectum are associated with a significant local and distant recurrence rate. Not all patients are appropriate candidates for preoperative radiation therapy. Preoperative identification of those most likely to benefit from neoadjuvant therapy is important. There is no general consensus on the role of endorectal ultrasonography, computed tomography (CT), and magnetic resonance im...
متن کاملPreoperative staging of esophageal and gastric carcinoma
Preoperative staging is of paramount importance for a patient with cancer of the upper GI tract.

Esophagectomy is...
متن کاملComparing results of preoperative staging of rectal tumor using endorectal ultrasonography and histopathology.
BACKGROUND Preoperative clinical staging of rectal tumors is very important to allow surgeons make informed decisions about the types of surgeries that should be performed. Endorectal ultrasonography (ERUS) is one of the tools that has been commonly used in clinical staging of rectal tumors. The aim of this study was to evaluate the accuracy of the preoperative rectal tumor staging using endore...
