Hello Ly, first of all let me say how very sorry I am for your diagnosis. My husband was given the same diagnosis as yourself in April 2018 when he was nearly 51. He has small cell neuroendocrine cancer of the oesophagus too, located near the junction of his stomach. I understand the difficulty in keeping up with the nutrition and putting as many calories into you as possible, it's hard but must be persevered with. Adequate nutrition & hydration is so vital to withstand chemotherapy. My husband's saving grace was that within 2 weeks of being diagnosed, his oesophagus had closed completely and he had to have a feeding tube inserted into his stomach. This enabled him to put on weight (he had gone down to 9st 7, which at 6ft 2 made him look skeletal). Have you thought of making soups, packed with high protein lentils, chicken etc. & blending. Also there are protein powders you can mix with water instead of milk. There are also quite alot of protein bars, drinks etc in health food shops. This can be expensive but I found a good affordable selection for my husband in Quality Save. I don't know what chemo you're on Ly, my husband had 5 cycles of carboplatin & etoposide first. Then he had 10 cycles of radiotherapy to his main tumour. After that he went on a clinical trial which worked for 19 months . He then had some more chemo for 4 cycles but that was not effective. We are now waiting to see if he can access another trial. Try not to lose hope,  as my husband was told initially he could only live for a couple of months. Since that awful day when we received the news, life has been an emotional & physical rollercoaster, but there have been so many pleasures experienced along the way to soften the very darkest of hours. Be your own advocate Ly, use a loud voice to find the best treatment available for this rare cancer & search the internet for trials. You may find something that maintains it for many months & allows you to catch your breath again & enjoy the simple pleasures in life once more. I wish you all the best Ly, don't lose hope.
