<s>[INST] My dad, 73, has been diagnosed with Esophagel cancer stage 4 he also has pneumonia and a feeding tube to the stomach, plus a fistula eso/traq. He had a heart attack 30 years ago. Dr has said that cant do anything for him. No chemo, radiation, anything. That chemo wd kill him in a week. Do you agree. What is the time frame? [/INST] Hi, dearI have gone through your question. I can understand your concern. Your dad has esophageal cancer stage 4.  No surgery will help. Treatment options are chemotherapy and radiotherapy. Despite of treatment prognosis remains poor. Life expectancy is not good. He has not good health so chemotherapy side effects leads to worsening of life.  There is no major difference between lige expectancy with or without chemotherapy. Consult your doctor and plan accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using health care magic. Wish you a very good health. </s>
