[|AI|]  Thanks for your question on Chat Doctor. Treatment, prognosis and life expectancy of any cancer is depended on its staging. And this goes true with esophageal malignancy. So to determine staging in his case following investigation s are needed.1. CT scan of neck to see for local extent of disease.2. PET scan to see for distal spread of disease. If distal spread is present then it is known as stage 4 cancer, and it carries poor prognosis. Life expectancy is less than 1 year. Only palliative chemotherapy and radiotherapy is given. In the absence of distal spread surgical removal of esophagus with clear margin is the treatment of choice. Post-operative chemotherapy and radiotherapy is given to prevent local as well as distal spread. In these cases life expectancy is less than 5 years. Overall esophageal malignancy is not having good prognosis because of poor feeding issues after surgery.
