My brother was diagnosed with Terminal stage 4 oesophageal cancer in March. He is coming up to his 5th ECX infusion next week. The scan after the 3rd infusion showed a small reduction in the size of the cancer. Jumping forward, when his treatment stops after 6 cycles and taking in to account his original terminal diagnosis, assuming that there is still some cancer there, what happens to it - will it automatically start to grow again and if so, what would be a realistic average life span or might it just stay the same reduced size and if so, is there any possibitilty / probability of a long life ahead. I expect the former is true and would prefer to have a realistic picture of what lies ahead.
