Pulmonary Carcinoma In A Dog
by LGraham - July 8, 2025
Buster, 11 yo MC Brussels-Griffon X (could be 2-3 yrs older?), 7 KG, BCS 4/9, diagnosed with pulmonary carcinoma

Main goal:
Primary owner (my partner) does not want to pursue chemo or radiation therapy, due to potential side effects, costs, and QOL concerns. Patient is already on XCHT (for hypercalcemia, see below), and I'm contemplating adding modified XFZYT. Open to other suggestions, especially considering that after LU lobectomy earlier today, my very experienced/excellent surgical colleague said he "didn't like how the mass was trying to invade the hilus" (he took as much as he could, but is suspicious that the margins will be dirty), and "didn't like the appearance (color, texture, size, etc) of the lymph node".

Do not have a current T&P dx, as patient has been under anes twice in last 5 days. However, I will update this post with info later this week, once he's off some of his postop drugs. I didn't think of doing it last week before anes :( Overall, he's a slightly deficient, older dog with Liver tendencies (fussy about certain things, such as his ears and nail trims ).

Picky eater, not food motivated; current diet is Dr. Harvey's Paradigm and/or Raw Vibrance base with cooked salmon or pork or beef (primary owner is immunocompromised and therefore prefers not to feed raw).

Bloodwork: CBCs consistently normal; most recent CBC (today) normal except for elevated platelets (476K) and slight monocytosis. Chemistries historically normal, including last week, except for incr Ca (12.3 mg/dl) and slightly incr ALP (has been around 130 for the last 5 years).

Clinical History:
1 - Pulmonary carcinoma
mild, non-productive, static cough, approx 6 mo duration
- thoracic radiographs in March 2025 were suspicious
- due to struggles to get reliable images of cranial thoracic area, thoracic/abdominal CT w/ U/S guided aspirates done 7.3.25, confirming R cranial lung lobe mass, aspirates confirmed carcinoma

2 – hypercalcemia (primary hyperparathyroidism)
- serum Ca fluctuating between 11 - 12 mg/dl over the last 2-3 years; crept up tor 13 on bloodwork done prior to a March 2025 dental
- parathyroid panel done June 2025; N PTH in face of incr iCa (1.74 mmol/L); Parathormone Related Protein 0; cervical U/S confirmed a R parathyroid mass
- started XCHT 3 weeks ago, which has dropped the iCa from 1.74 to 1.53 mmol/L
- decided not to pursue parathyroidectomy today, due to the possibility of the thoracic mass being a high grade/invasive carcinoma, and the fact that this dog does not do well with repeated blood draws or prolonged hospitalizations.

3 – C 6-7 disc disease
- apparent on thoracic rads
- one episode, July 2024, of significant R-sided neck pain (medically managed), with root signature sign; intermittent, mild R forelimb lameness was noted summer/fall 2024, during which time he received Meloxicam PO 0.7mg (0.1 mg/kg) and occasional chiro adjustments.
- no obvious issues w/in last 6 months, no meloxicam given

4 – atopic dermatitis/chronic otitis externa
- ongoing mgmt w NCSU Derm team
- currently on weekly immunotherapy, w/ rare Cytopoint injections
(peak pollen times – spring & fall), plus topical Posatex daily AS + weekly AD
- when ears flare, typically very low grade yeast, but the most recent AS flare was rods, tx with short course of Florfenicol.

5 – KCS, pigmentary keratitis, endothelial dystrophy/degeneration, intermittent corneal edema w/ historical corneal ulceration
- ongoing mgmt w NCSU Ophtho team
- currently on topical OU Diclofenac q 12, Tacrolimus q 12, Muro-128 5% (saline ointment) q 8, artificial tears at night (q 24)
- despite consistent tx, pigmentary keratitis is worsening

I am just chiming in because my own 12.5yo Stella was diagnosed with bronchogenic carcinoma last October and I contacted Dr Marsden about it. You can maybe find it in the forum? She has been on modified XFZYT, XCHT, and LJZT + turkey tail and lions mane + ApoCaps since and is 9mth out and doing well. She still has an occasion gagging cough, has definitely lost muscle mass, but she still has a healthy appetite and goes for hikes with the other pups. I found the Liu Jun Zi Tang really helped with her reduced appetite.

But obviously, Dr M will give the most solid advice,

Thanks Corinne - adding LJZT is an excellent suggestion. I'll assess his T&P later today, but I'd bet LJZT will fit him well, esp for his picky appetite in general. He's 3 days post op, and isn't eating as well as I'd like him to, so it seems like a good fit based on current signs (side note, he last ate well at about 36 hours post op, a few hours after I had given him some injectable ondansetron & maropitant - so again, prob a good fit for LJZT).

Hi LG!

I agree that a Liu Jun Zi Tang + Modified Xue Fu Zhu Yu Tang + Xiao Chai Hu Tang combination (full doses of each) should stabilize this case. I would expect further improvements in hypercalcemia and allergy symptoms, and the beginnings of improvements in the cough and KCS within a few weeks at the outside. I have repeatedly found enduring stability of primary lung tumors on the above protocol, even in humans, adding years to lifespan. Hopefully this dog enjoys the same benefits. The real food diet should be continued for maximum benefits and any other therapies you want to add in addition (such as IP6, garlic, omega 3s, tumeric, Apocaps, etc. will all be fine with these formulas).

Let us know how it goes!
