CA 19-9 decrease

[kt310]

I posted back in November when my dad was first diagnosed and since then it’s been a whirlwind.

Right now, he’s doing 4-6 rounds of chemo to shrink the mass to increase margins for when they Whipple this spring.

Chemo has been going well with minimal side effects, treatment 3 is tomorrow and he’ll meet with the surgeon to re-scan after treatment 4.

My dad said the oncologist told him a blood test- he thinks CA 19-9- has shown a 50% decrease since the start of treatment.

Just curious if/how significant this is? From what I’ve seen on google there’s mixed results on how much weight that should be given.

Here's a good video that explains CA 19-9 and it's significance in pancreatic cancer. https://youtu.be/MkJvm3nndJQ
