I don’t believe CA19-9 values have any meaning. When I was first diagnosed with stage 1 pancreatic cancer my CA19-9 was 256. After 8 rounds of chemo and radiation my CA19-9 is 13.8, but yet I now have stage 4 with mets to the liver, tumors continue to grow. I, like most of you, was encouraged by the counts, but to no avail.
