The risk of relapse of colorectal cancer depends on tumor characteristics such as location and Dukes' stage. Recurrences may be metastatic only (70%), locoregional only (20%) or both (10%). The main objective of postoperative follow-up is to detect recurrent disease as early as possible, in order to allow curative resection. Most relapses are now diagnosed when still asymptomatic. Different imaging methods help to diagnose these recurrences. The CT scan allows to examine the liver, lymph nodes, anastomosis and the pelvic cavity. MRI can bring complementary information in some selected cases. Lastly, percutaneous needle biopsies will be useful to prove the diagnosis. For the detection of distant metastases, chest X-ray, hepatic echography and CT scan examination can be used.
结直肠癌复发的风险取决于肿瘤特征，如位置和 Dukes 分期。复发可能仅为转移（70%）、仅为局部区域（20%）或两者皆有（10%）。术后随访的主要目的是尽早发现复发性疾病，以便进行根治性切除。现在大多数复发在仍无症状时被诊断出来。不同的影像学方法有助于诊断这些复发。CT 扫描可用于检查肝脏、淋巴结、吻合口和盆腔。在某些特定情况下，MRI 可以提供补充信息。最后，经皮穿刺活检有助于确诊。对于远处转移的检测，可使用胸部 X 光、肝脏超声检查和 CT 扫描检查。
