Preoperative 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 کاملUltrasound Methods for Lower Rectal Cancer Staging
For ERUS the patient is prepared with an enema 2h before the study. ERUS is performed in the left lateral decubitus position and always starts with digital examination. Usually no sedation or general anesthesia is needed and the procedure is well tolerated by the patients. After a digital rectal examination is performed the probe covered with a balloon is inserted into the rectum. For better ac...
متن کاملEvolving standards in preoperative staging and treatment of rectal cancer.
Colorectal cancer has become the commonest cancer in Hong Kong since 2011 and rectal cancer constitutes about one third of all colorectal cancers.1 Rectal cancer has a much higher local recurrence rate of about 10% than colon cancer.2 Hence, stern efforts must be made to safeguard patients from recurrence during the management of rectal cancer. In current practice, good oncological outcome with...
متن کاملEfficacy of High Resolution Magnetic Resonance Imaging in Preoperative Local Staging of Rectal Cancer
OBJECTIVE To assess the efficacy of high-resolution magnetic resonance imaging (HRMRI) for preoperative local staging in patients with rectal cancer who did not receive preoperative radiochemotherapy. METHODS In this retrospective study, 30 patients with biopsy proved primary rectal cancer were evaluated by HRMRI. Two observers independently scored the tumour and lymph node stages, and circum...
