[Radiofrequency ablation for postoperative recurrent of metastatic lesions of esophageal cancer].
Radiofrequency ablation (RFA) was performed for the postoperative recurrent of metastatic lesions of esophageal cancer in 6 patients. All patients were males, and the median age was 59. Surgical curativities were A (3 cases), B (2) and C (1). The recurrent sites were intramediastinal omentum of gastric tube (2 cases), rt lung (2), rt adrenal grand (1) and liver (1). Four cases had a single recurrent lesion and the two had multiple lesions consisted of a single lesion as RFA target, and the lesions in a different site that were simultaneously treated by other therapeutic modalities. The median time of recurrence was 12 months after esophagectomy. RFA was performed once in the 3 cases, and twice in the other 3 cases. Therapeutic effect evaluated by CT was CR (2 cases), PR (3) and SD (1). No serious complications associated with RFA procedure were observed. Three patients died due to cancer recurrence within 7 months after RFA. However, RFA-treated lesions were well controlled to the end. RFA are safe and minimally invasive, thus, can be repeatedly performed technique that can induce a good local control of the target lesion equivalent to surgical resection. RFA is applicable as an effective local therapy for the recurrent or metastatic lesions of esophageal cancer.
