<s>[INST] my father has stage 4 esophagus cancer he has had a year of chemo and today they stented the tumor area and took another biopsy. The tumor is protruding into the upper most part of the stomach stightly, but everything else looks good the dr said. I am just wanting to know what the chances of his survival with this cancer now protruding in the stomach area? what other steps other then the chemo should be done. They have done a wonderful job so far but cancer is just one of those things to me that Is treatable but is it curable? [/INST] Hi and welcome to Chat Doctor, thank you for your query. Stage 4 is practically not curable, even stage 3 isn't. Esophageal cancer is very serious disease with poor prognosis, but you should fight and give your best to make all this easier for your father. If this isn't operable and obviously isn't if there is involvement of surrounding tissue and organs then chemo is the only possible treatment-Everything else is palliative. He may have resection of stomach and ileostomy formation when obstruction develop and that's everything that surgery can do. Wish you good health. Regards. </s>
