Unfortunately cancer doesn't follow many rules about how it responds to things. My second rottie B'Elanna had paraneoplastic syndrome with immune-mediated hemolytic anemia, a very similar condition. We thought she just had IMHA until her stomach literally fell apart. She responded to treatment (she was on prednisolone, azathioprine, doxycycline, and azithromycin for suspected Bartonella infection) slowly for about a month, then just crashed and burned. We thought it was a perforated ulcer due to the pred, but the surgeon said her whole stomach was very friable, and biopsy results which came up a week after she died said she had cancer. We tried to get her stomach back together, but she had post-surgery complications (pulmonary thromboembolism, probably stomach fell apart again), so I had to euthanize her.
