摘要
目的：探讨喉癌放疗后MR复查的临床价值。材料和方法：回顾性分析37例经病理证实的喉癌放疗后MR复查的表现。结果：18例单纯放射治疗、17例喉癌术后6～8周开始放疗、2例术后2年发现复发而行放疗。放疗后第6周MR示局部不同程度水肿，3～6个月后水肿消退，肿瘤范围也渐缩小或消失，但其中4例分别于1年、1年半、3年和6年MR复查示慢性水肿；单纯放射治疗后复发2例，术后放疗后复发5例，喉部分切除术后放疗后喉狭窄合并感染1例。结论：MR复查能观察喉癌放疗后出现的反应性水肿、慢性淋巴水肿、喉狭窄、原发肿瘤的好转和复发性喉癌。
Abstract
Objective: To explore the clinical value of follow-up MR scans after radiotherapy for laryngeal carcinoma. Materials and Methods: To analyze follow-up MR appearances of the larynx in 37 patients of laryngeal cancer with pathological evidences after radiotherapy. Results: Eighteen patients received merely radiotherapy. Seventeen patients received laryngectomy and post-operation radiotherapy 6 to 8 weeks after operation. Two patients received radiotherapy because of recurrent carcinoma two years after operation. MR appearances showed edema with different degree at the sixth week, and extinct at the third to sixth months after radiotherapy. The affected range of tumor also reduced or disappeared gradually. Four patients showed chronic edema after 1 year, 1.5 years, 3 years and 6 years respectively. Recurrent tumors were found in two patients after merely radiotherapy and in five patients after operation and post-operation radiotherapy. One patient showed laryngeal stenosis with infection. Conclusion: Follow-up MR scans can provide reliable images about reactive edema, chronic lymphedema, laryngeal stenosis, improvement of the primary tumors and recurrent laryngeal carcinoma.
