Argon plasma coagulation for a patient with locoregional failure after definitive chemoradiotherapy for esophageal carcinoma: a case report.
Patients who undergo definitive chemoradiotherapy (CRT) face a risk of residual resistant disease or disease recurrence at the primary site; therefore, salvage treatment may be required. An optimum strategy to minimize these risks clearly needs to be established. Argon plasma coagulation (APC) is a safe and convenient procedure now applied widely for therapeutic endoscopy. In this report we describe the successful use of APC over 6 years for the treatment of recurrent esophageal cancer after CRT. A 61-year-old Japanese man underwent CRT for a thoracic esophageal cancer. Pathological examination before CRT revealed a well-differentiated squamous cell carcinoma. Locoregional failure was observed 2 years after CRT, and an initial APC treatment was performed. The patient has now undergone APC ablation 7 times with no postoperative complications. No metastasis to lymph nodes or to other organs has been detected during the last 6 years. The usefulness of APC as a salvage treatment for locoregional failure after definitive CRT has not been established. In our experience, salvage APC is the best treatment option for some patients.
