Argon plasma coagulation for superficial squamous cell carcinoma in the residual esophagus after esophagectomy.

Abstract

BACKGROUND:

Patients after esophagectomy for esophageal squamous cell carcinoma (SCC) occasionally develop metachronous SCC in the residual esophagus. Although most of these second primary lesions are detected as superficial cancer at follow-up endoscopy, it is often difficult to perform endoscopic resection for these lesions near the site of anastomosis.

METHODS:

The objective of this study was to evaluate the effectiveness of argon plasma coagulation (APC) for superficial SCC in the residual esophagus after esophagectomy. Twelve patients (involving 15 s primary lesions) received APC for superficial SCC in the residual esophagus after esophagectomy. These lesions were difficult to perform endoscopic resection and they were treated using APC.

RESULTS:

There was no treatment-related complication. Complete remission (CR) was achieved in 13 (86.6%) of the 15 lesions: CR was achieved in 11 lesions (73.3%) after the first APC course, and in another 2 lesions (13.3%) after two or more APC courses. Of the 2 patients with persisting residual tumor, 1 patient received 12 times repeated-APC courses over 6 years, and eventually achieved local control without metastasis, the other patient received radiotherapy and cervical esophagectomy after treatment failure with APC. All patients survived except for one patient who died of old age and another patient who died of tongue cancer.

CONCLUSIONS:

APC was a safe treatment that was easy to perform. APC was concluded to be an effective treatment for superficial SCC in the residual esophagus after esophagectomy when endoscopic resection was difficult.
