Interpret a “malignancy panel”
Low PTH: high calcium
PTHrp +: tumor present in the body
Elevated Ca, ↓ P, ↑ PTH = hyperparathyroidism
Why should you not tx with prednisome until samples for dx are taken?
Because it treats lymphoma
What is contained in mast cell granules
Histamine
How does increased histamine and gastrin induce ulcers
Histamine receptors cause ↑ acid production
Excess gastrin = gastric hyperacidity
How do you tx ulcers?
H2 blockers, proton- pump inhibitors
Sucralfate

How do you tx insulinoma
Surgical removal pancreatic mass
Glucagon and dextrose infusion (CRI)
Avoid sugars, small frequent meals
Pred, diaxoide and streptozoticin
What is the cause of anemia in most cancer patients?
↓ RBC production, serium iron derangement, ↓ RBC lifespan, and disordered erythropoietin
What tumor-types are associated with DIC?
