直肠癌(Rectal Cancer)是发生于直肠黏膜上皮的恶性肿瘤,占大肠癌的65%左右。其发病与饮食、遗传等因素密切相关,早期诊断和治疗
Rectal cancer MRI is a rapidly evolving field of radiology. Clear understanding of key pelvic anatomic landmarks and their clinical implications along with awareness of several prognostic features at baseline MRI and after completion of neoadjuvant chemoradiotherapy is crucial in order to guide accurate...
The aim of this review is to analyse the risk and the pattern of local recurrences in rectal cancer and to provide an overview of the role of imaging in early detection of LRs. We performed a literature review of studies published on Web of Science and MEDLINE up to January ...
Guidelines recommend chemoradiation (CRT) before surgery for patients with clinical stage II-IIIrectal cancerin order to lower the risk of locoregional recurrence, but there is a growing concern among oncologists that the approach leads to overtreatment. But the issue has been how best to identify ...
If metastatic (local or systemic) rectal cancer is suspected, the following radiologic studies may be obtained: CT scanning of the chest, abdomen, and pelvis Pelvic magnetic resonance imaging (MRI): Preferred study Endorectal ultrasonography: May be used if pelvic MRI is not readily available ...
(DW-MRI) are correlated with molecular markers Ki-67, hypoxia-inducible factor 1α (HIF-1α), and vascular endothelial growth factor (VEGF) in rectal cancer (RC).Materials and MethodsNinety-one patients (64 males and 27 females) diagnosed with rectal cancer underwent 3.0T DW-MRI before any...
我国直肠癌(Rectal cancer,RC)发生率与结肠癌发生率接近1∶1;低位RC所占比例高,占RC总发生率的60%~75%;近年来,RC比例有下降趋势;青年人RC比例较高,占10%~15%。 临床表现 早期RC可无明显症状,病情发展到一定程度可出现下列症状:①排便习惯和性状改变;②大便逐渐变细;③直肠刺激症状;④肿瘤侵犯膀胱、尿道、阴...
