It appears that the primary tumor was at the gastro-esophagealjunction. This is usually (but not always) an adenocarcinoma. Theaseadeno-carcinomas are not usually responsive to radiation therapy. So thedecision about radio-therapy depends on what the pathology of the resectedtumor showed.
2. I am not sure what this question means.
3. Limited to months not years on an AVERAGE. Some patients may live longer.

5. I would consider placement endoscopically of a stent if this is feasible. This will improve his quality of life and allow him to take something by mouth. However, this procedure will not do anything to the tumor itself. I think at this stage it is more important to consider improving quality of life rather than only prolonging life (which may mean more suffering).
