In a patient with distal esophageal cancer with a single non-regional neck lymph node, would you offer chemoradiation therapy or surgery to the primary site if the lymph node has a complete radiographic response after chemotherapy? 

If the patient continued to have dysphagia or disease in the esophagus, that would push me to do consolidative chemoradiation. If they are enjoying a good quality of life and no swallowing symptoms and no evidence of disease, I don't believe there is enough data to uniformly recommend chemoradiation...
