直肠癌术后放化疗后近期MRI观察

MRI observation of patients with rectal carcinoma after operation and postoperative radiotherapy and chemotherapy

目的 :使用MRI评价直肠癌术后放化疗后的近期疗效。方法 :选择我院 2 0 0 0年 3月～ 2 0 0 2年 10月直肠癌术后放化疗后 6～ 12个月患者 3 5例 ,行临床和其它影像学检查筛选确立重点检查部位 ,然后分别行盆腔、肝脏、脊柱等部位MR扫描 ,由 3位高年资医师阅片 ,统计复发和各部位转移例数。结果 :直肠癌局部复发伴周围转移 9例、肝转移 7例、脊柱转移 3例、多发转移 2例。结论 :直肠癌术后放化疗后近期局部复发较为多见 ,肝脏转移是其远处转移的主要形式 ,MRI是追踪其近期疗效的一种非常有效的手段。

Objective:To evaluate the recent therapeutic effect of radiotherapy and chemotherapy after operation in patients suffering from rectal cancer with MR imaging.Methods:35 patients with rectal cancer 6～12 months after operation and postoperative radiotherapy and chemotherapy were scanned with MR imaging after clinical and other radiological examination. The local recurrence and distant metastases of rectal cancer were analyzed.Results:The MR findings included: local recurrence (9 cases),liver metastases (7 cases),spinal metastases (3 cases) and multiple sites metastases (2 cases).Conclusion:Early local recurrence in patients with rectal cancer after operation and postoperative radiotherapy and chemotherapy is very common. Liver metastases are more common than other distant metastases. MR imaging is a very useful method for observing the recent therapeutic effect.
