but would it have chaged the ultimate outcome?

This dog presented flat over the weekend with some melena. Liver values off the scale on bloods, abdo scan revealed a heterogenous, irregular spleen and a liver mass. He went downhill despite supportive treatment and was PTS on Sunday.

I feel horrendous that I didn't pick up on this sooner - once cytology came back as a MCT I should have started the work up; bloods and abdo scan, rather than just thinking about surgical removal. Perhaps this might have been detected sooner and I wouldn't have given the owners any false hope.

Panic over - I saw the dog this evening for a pre-op check, and the mass has disappeared, with a draining tract now present!

Now this is either a miracle cure, or it was an anal gland abscess all along and the FNA was misinterpreted. I'll speak to Idexx tomorrow!

It sounds like it would be worthwhile to do an incisional biopsy to grade the tumour so that you can assess the likelihood of getting adequate margins in this specific case. Although it requires another GA, I find owners are usually keen once they understand the implications of treating MCT, and if it is high grade, it avoids the dog undergoing a procedure which will not be curative. Good luck.

Hi,

I treated a dog with MCT a few yers ago, it was on the carpus, the dog was 13 and chemotherapy or amputation wasn't an option. I tried Masivet and was very happy with progress, the tumour shrank within 10days , the leg was almost normal, of course its not going to last long-term. They say 4-6 months, but we were not planning to debulk it. It gave us 13 months of normal life . I guess in your case I would give Masivet a go and then try to cut as much out as you can, but considering the location it s likely to be high grade MCT.
