Anyone have experience with gastrointestinal stromal tumor (GIST)?

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?

Thank you for sharing the link, will be surely helpful for me as I'm still new to GIST and still thinking about doing surgery or not.

Hello all,
I've had a CT scan of the whole abdomen last month because of a pulsating rhythm in my stomach. They found a large mass lesion of 8.8x9.9 x 10cm by size and said it's a possible GIST.

I'm now going to try Immunotherapy hoping it will shrink before going for surgery.

Hope we can all help each other by sharing our experiences here.

Thank you.

Hello @avidthinker and welcome to Mayo Connect. I appreciate you joining this discussion on GIST. I so like what you said in your second post about how important it is to have "a specialist that specializes in GIST and to seek second opinion if you are not comfortable with your current medical provider." Those are some important guidelines that can help you advocate for yourself when you have a health issue, especially if it is rare.

You mentioned that you are considering surgery. Does this indicate that a physician has recommended surgery at this time?

Are you comfortable sharing more about your journey with GIST? If so, please share what your symptoms were and how this was diagnosed.

Mine was larger than yours and they removed it (ended up in ER). Currently (3 mo later) on Imatinib and doing great.

Thank you for the warm welcome, will post more once there are changes and improvements after a month.

Look into joining the GIST Support International ( gistlistserv)
There is an online support group with a wealth of information and support for patients ,caregivers and families. It has been a lifeline for a dear friend when newly diagnosed Most important is to have a specialist that specializes in GIST and to seek second opinion if you are not comfortable with your current medical provider.
