Mast Cell Tumors In A Dog
by equinesportsmed - January 10, 2023    View Case Report
Hi Steve and Erin--

Patty is a 9 year old FS lab with a long history of low grade MCT. She has been managed with herbs and anti-inflammatories, and over the past 5 years has had various small lesions on her extremities removed. Last October, one of her lesions, on her trunk, came back as high grade, and the surgeon recommended chemo, which she started a few weeks ago.

I have had her on modified XFZYT since August 2021, and added some 6 Gentlemen when she had a day of GI upset post-chemo. She has had 2 treatments (CHOP, I believe) so far, and seems to have episodes of heat a few days later. I think the oncologist is happy with her response. When I saw her yesterday, I was struck with how her lavender tongue and toned pulse seemed more like a XCHT case. And this latest tumor definitely came up in the fall. Might I conclude that the modified XFZYT is not cutting it for her (since she has continued to get mast cell lesions while on it), and she might derive more benefit from XCHT?

Her energy and attitude remains good, but she has episodes of hind end weakness and pain. Her mobility was reported to be better after an AP treatment yesterday-- BL 18, 23, 25 and right limb points. I also sent her home with some Hoxsey to be given if she has another post-chemo hot spell.

Thanks in advance,

Karen

Hi Karen,

I commonly use Xiao Chai Hu Tang to back up mXFZYT in mast cell cases, so that's a good news. You could look at the existing herb/chemo protocol as having 'peeled a layer of the onion', showing you the underlying cause of the Blood stasis, which is commonly a Shao Yang disharmony

Heat signs can be associated with Shao Yang disharmony, so XCHT may take care of them. Other causes to keep in mind post chemo are Qi deficiency and Yin/Blood deficiency. You've addressed these two, but if you're only using Six Gentlemen here and there, you could be more consistent with it and see if the Heat signs vanish. Or maybe they will vanish with the XCHT. If not, then you have your Hoxsey to resort to

So add XCHT to the modXFZYT, not replace, right? I *think* they have been giving 6G continuously, rather than symptomatically because she asked for a new bottle-- mom has been out of town since the holidays, so communication with her partner at home can be a little haphazard.

Thanks so much!

Yes, I would add it. mXFZYT has probably been helpful and should likely be reinforced, instead of discontinued
