Stomach Cancer

"Our son is 44 yrs. old and had been diagnosed with stomach cancer in Nov of last yr. After given chemo (Oxaliplatin) and Xeloda).It shrunk the tumor, but it damaged his nerves in his feet. In April of this yr. he had his stomach removed.The surgeon said it was the slow growing kind (neuroendocrine). Six weeks thereafter, another tumor grew back in the same area. This time it was the aggresive kind (adenocarcinoma) and now he also has a few spots in his liver.The chemo they tried (Ironotecan and Xeloda) shrunk the new tumor about 1/4 in size, but now the spots in the liver got somewhat larger, but didn't spread. They are now trying Herceptin along with (carboplatin, etoposide, and a shot of neulasta.There will be one more round of these starting on Oct 26th before another CT scan. We have been researching every day to find a procedure that would be effective with stomach cancer. When we asked about radiation with the Chemo, we were told that radiation hasn't been proven to extend the life of a patient, but all the success stories that we've come accross seem to be a combination of Chemo and radiation.We also heard of proton therapy, however we don't know if this applies to stomach cancer and what the risks are. It seems to us that they have given up on a cure and are just trying to maintain the cancer at this point. We refuse to give up. We are trying to advise him to get a second opinion while he is on Chemo because it takes six weeks to get another scan to see if it's working, if it's not working again time is slipping away from us. Dr. Jaggernauth, what would you suggest as to our options relating to the stomach cancer at this stage? Please help."
