stomach,liver and lymph nodes have tumors

Barbara F

My husband was diagnosed in June and has stomach,liver and lymph node tumors. The cancer is stomach and he is bloated and has already had his stomach drained once, but his feet and legs are swollen and the diarretics aren't working. I want to know if anyone else has had such a case of this cancer when so many things are involved. Is he doing the right thing to be on a clinical trial? Will this get him into remission or just relieve the pain?
