Hello @shannona and welcome to Connect. I see that you recently posted about GIST tumors in your pelvis and omentum. I am sure that you are glad that your tumors appear to be shrinking.

You are asking some good questions about immunotherapy. As I looked for other members with cancer in the area of the pelvis and omentum, I see that many are members in the area of gynecological cancers. Was the cancer in your pelvis a gynecological cancer as well?

I did look for some information on GIST tumors and immunotherapy and found information on the National Institute of Health website:

--Current Status of Immunotherapy for Gastrointestinal Stomal Tumors
https://pubmed.ncbi.nlm.nih.gov/28186088/
Have you discussed the option of immunotherapy with your oncology team?
