Tumor w/ minor grow with no Octreotide & larger growth w/ the shot

I was diagnosed with metastatic neuroendocrine cancer in the liver 4cm x 3.1 cm in Sept. Grade 2, non-functioning, well differentiated KCI 6-8%. My MRI in Dec measured it 4.2 x 3.4 when I received no treatment. Very minor change.

My March MRI after receiving 4 shots of Octreotide showed the tumor measuring 5.2 x 2.4 3 months later. The 5.2cm showing 30% growth with treatment. Other side of the tumor declined 30%.

Another tumor was .8 x .9 in Sept and .9 x .9 in Dec and 1.5 x 1.3 in March. 36% and 44% larger.

It seems to me that there is more growth now with Octreotide than when I was not receiving treatment.

I wonder if anyone else had the same experience. The PA simply said it might have been even been more growth if I had not had the treatment.

Wondering how the decision is made that Octreotide or any treatment is effective.

My glucose has gone up every month I have taken the shot, and now is 50% higher than when I started. Bilirubin has gone up the same amount and I am low on iron and % saturation for iron. Known side effects.

I intend to discuss with the dr on my next appt. Interested in others experience. Thanks.
