DIAGNOSTIC ACCURACY OF COMPUTED TOMOGRAPHY FOR T STAGING OF RECTAL CANCER
Main Article Content
Abstract
Background: Rectal cancer is the third most common cancer and one of the leading causes of death in many countries worldwide. Early detection of rectal cancer plays an important role in the treatment and prognosis of this disease. In Vietnam, there are few studies on multi- detector CT (MDCT) and multi-plane reconstruction (MPR). Objective: To investigate the value of MDCT in diagnosing T-segmentation of rectal carcinoma. Materials & Methods: A cross-sectional descriptive study was conducted on 154 patients diagnosed with colorectal cancer who underwent MDCT and MPR before treatment at Bai Chay hospital from January 2018 to May 2022. Data was collected from the parameters of the MDCT according to the guidelines of the AJCC system version 8. The CT-scan reports are recorded independently of the pathology reports. Results: 102 cases of colorectal cancer were collected and analyzed between January 2018 and May 2022. Multi-sequence CT is highly valued in assessing the invasion of the superior mesenteric, perirectal fascia, peritoneum and adjacent organ with high sensitivity and specificity.
