Key Quotes

“Currently we have about 30 different subtypes of lymphomas that are classified in dogs, and each of them again have their own specific diagnostic criteria, specific treatments, and prognoses.”

“CHOP is four different chemotherapy drugs... and there are essentially 16 treatments given over a 19 to 25 week protocol.”

“If we have, say, a more resistant phenotype or tougher type of lymphoma like a T cell, we really shouldn’t be treating them with CHOP. We should be using a LOP or a MOP based protocol.”

“The survival times (with half body radiation added) were over 2,000 days. So you’re talking like, you know, essentially six years.”

“A typical CHOP protocol at our hospital can sometimes range anywhere between $8,000 to $16,000 plus.”
