PET scan questions

I was hoping for some insight on a PETscan I recently had. Since I've been having ongoing bowel obstruction symptoms and a SLOW rising ca125 my surgeon wanted me to have a PET/CT. The CT scan was clear but the PETscan showed one hotspot on my colon. The oncologist said it would unusual to have only ONE hotspot on a PETscan in cases of a reoccurence. My CA125 actually went down from a 14 to a 10 and the catscan was clear. He cannot confirm or deny a reoccurence and wants me to have a colonoscopy. Has anyone heard of a similar finding. I'm hoping the hotspot is nothing more than a polyp. Also, is brain a mestastic site for ovarian. I've been suffering from headaches and very paranoid!

Here is my experience with a Pet Scan. I had a CT scan and a Bone scan. All was clear. Then I had a Pet Scan and it picked up an enlarged lymph node in my arm pit. I had surgery to remove the enlarged lymph node and guess what? All it was, was an enlarged lymph node. That lymph node had been that way for 25 years. The only reason they took it out was because some lymphoma's can lay dorment for years and years. Sorry, my spelling is not that great. Hope this info helps you out. Paula

I would think a colonoscopy would be in order, especially with obstruction problems. PET scans can be more accurate indicators of cancer activity than CTs, because they target the disease.

Have you spoken to your doctor about your headaches? Are you drinking enough water? (my husband always suggests dehydration when I have a headache, and sometimes he's right..)

I have never had a PET, but the CT scans showed one tumor on my colon after a bout of diverticulitis. After we fought the bowel disease with anti biotics and hospitalization, the tumor showed up in the same spot. I did not have a colonoscopy because it is close enough to the rectum that it can be felt with a physical.
It was not felt two weeks ago after 4 doses of carboplatin. And all of the left side pain is gone.

I believe the brain is a mestastic site. I would ask my doctor for sure.

Hi Nancy, Many times there are areas in the pet scans that are not cancer even though they light up. I know I have areas in my chest wall and other lymph nodes that light up but have never shown on the ctscan and by now they should have. I knew of someone also who had areass that lit up, not ovarian cancer person, but when they biopsied it was not cancer. Just thought I'd toss that out. Prayers for peace for you. Hugs bonnie

I had headaches for awhile, too - everyday. I asked my doctor the same question: does OVC spread to the brain. He said it's rare, but can happen.

My doctor said OVC usually stays in the lower part of body (organs), but can spread to bones.

HI Nancy. I don't usually comment on these boards, just lurk and loiter. I lost my mother to uterine cancer in June. I wanted to comment on your pet scan question. What were your SUV nos. Did they say? When we received my mother's diagnosis of Stage IV based on a cat scan and then pet scan, the dr. kept mentioning the SUV . My sisters and I were like what the hell is he talking about. Anyhow, the SUV stands for standard uptake volume and it's a measurement of how much cells light up during the pet scan based on how much of the radioactive glucose they take up. The theory being cancer cells are gluttons and more active and will take in more of the solution. A reading higher than 2.7 is malignancy per my mother's gyn/oncologist. DO you know what your SUV nos. were. If the hotspot had a lower no. than that, it's most likely not malignant. There can be alot of false positives and negatives with these scan as well. Infection, inflammation can all make things light up.
I hope this info. helps you.

thanks for that golden nugget. I have had 3 or 4 PET/CT's and although I saw that SUV on the report, never quite understood. It all makes sense now.

Thanks for the input...very interesting! My suv was 4.7 and yes, it was malignant. 13mm area that was undetected on ct scan.

Nancy: I have not had a Pet Scan yet, but my Oncologist told me that Ovarian Cancer does not spread to the brain. It is very very rare.
