Complete regression of esophageal cancer with concomitant liver metastasis achieved by concurrent chemoradiation therapy.

We report a patient with esophageal cancer with concomitant liver metastasis in whom complete response was achieved by chemoradiation therapy. A 66-year-old man was diagnosed as having stage IVB esophageal cancer with synchronous metastasis in the liver and cardiac lymph node, and concurrent chemoradiation therapy was started. The chemotherapy, consisting of 5-fluorouracil (300 mg/body per day, continuous infusion) and low-dose cisplatin (5 mg/body per day on 1-5 days every week), was performed for 7 weeks. In addition, radiation therapy (2 Gy/day on 1-5 days every week) was employed for both the local and the metastatic lesions, along with the chemotherapy. Throughout the course of this therapy, the patient did not experience severe toxicity, and this chemoradiation therapy resulted in complete regression of both the local and the metastatic diseases. Subsequently, he was followed-up as an outpatient without any maintenance therapy, and he has been free of disease for 38 months after completion of the therapy. This concurrent chemoradiation therapy may be effective for esophageal cancer even with visceral metastasis.
