Most (but not all) cancer involving the urethra ends up being a form of transitional cell carcinoma (TCC). Besides the pressure on the urethra causing urinating problems the primary site ends up being the bladder. Although it can spread to other organs such as the lungs. You should ask the Vet(s) if they believe it's TCC. If the answer is yes, then you can try Chemo consisting of the drugs Mitoxantrone and Piroxicam. The Mitoxantrone is one of the more expensive Chemo drugs. For a dog the size of yours, you would want to ask the Vet for Metoclopromide 10 mg 3X daily for 72 hrs post treatment to control nausea. Mitoxantrone was not a problem for my Lymphoma puppy, when dosed with the Metoclopromide. The Piroxicam is a COX-2 inhibitor where the COX-2 is expressed as part of the TCC. Inhibiting its expression helps slow down the cancer. Piroxicam is also used in Vet medicine as an anti-plain, anti-inflamatory drug. It tends to be hard on the stomach and requires an acid blocker to prevent ulcers from occurring. Studies give this treatment Median and mean disease-free intervals 200 and 280 days, and survival times of 299 and 411 days. If money is an issue then Piroxicam alone gives about 181 days Median survival.Originally Posted by robinh
Discuss the Chemo option with your Vet(s). If they agree, then follow up on asking about getting supportive drugs to prevent nausea, along with the appropriate acid blocker dosage. It could give the dog a better quality of life in the remaining months, and also give you a little more time to spoil it even more.
