Question about PET scan finding

Options

Does anyone know what this with me? From PET scan report.


Several mildly FDG avid left axillary lymph nodes without enlargement or abnormal morphology are suspicious for nodal metastases in the setting of prior breast cancer. (Several mildly FDG avid left axillary lymph nodes are demonstrated, max SUV up to 2.8 without significant enlargement or abnormal morphology.)

    I believe it means they see some tissues in the left armpit lymph nodes which are suspicious.. They're not areas of enlargement or weird shape, just areas which are taking up the PET tracer - areas which are more metabolically active, which can be a sign of a malignancy. I'm guessing they recommend a biopsy?

    The oncologist said too small for a biopsy. He will do another CT in May and repeat blood work.

    Hmmmm..... so not necessarily good news though if it turns out to be something it should be caught quite early if it's too small to biopsy now??? And really staying on top of it by rescanning in May.... what to say? How are you feeling - I mean more emotionally b/c I could imagine really mixed feelings if I were in your shoes.....

    I hate the wait. Bone scan showed a spot on rib but CT and PET did not. CT showed small nodules on lung but PET did not. PET Showed lymph nodes but CT did not. Blood work was normal regardless. It’s been a stressful few weeks.

    Snowflake that is just crazy making!! I sure hope you have some in person support, interests etc. to help you during this next few months...Obviously you have this site too. It will be important you try getting more of the worry to the background as much as you can during the next few months.... Planting a seed - I've had 6 month "call backs" for things other than breast cancer. I find the first 2 weeks or so when notified about needing that next test is difficult though I am able to put that behind me when there's a long time-frame until that next test. Then a couple weeks before the test I start getting antsy again.. I hope you can find a process something like that so you have more peace and ability to live your life in-between....

    For the lung nodules if they are 5 mm or less then they are most likely not malignant and if they are under 1 cm I don't think the PET scan would catch either way

    Bone scans pick up everything but can't differentiate btwn cancer and benign- so if nothing on CT and Pet most likely is not a concern.

    2.8 SUV is something but not very high (if that makes sense) but is good CT doesn't show anything.

    Overall my fingers and toes are crossed for you and that in 3 months your scan is super boring and unremarkable and unchanged :-)

    Hello anyone here

    I would like to know if suv max 8 shown in report means cancer??

    Sherry2019, what is going on that prompted your PET scan? What and when was your diagnosis? Age, size, grade, stage, ER, PR, HR status? Can you provide more information from the report, rather than that little snippet? What is the full text from the report, and what are the findings and recommendations? I don’t think anyone can answer your question without a lot more information. It would be helpful since you’ve been here a while if you filled out your diagnosis profile information and set it to public so other members here understand what your situation is.

    sorry..I am in the mid 30s currently still under target therapy treatment, i was diagnosed last year stage 2 grade 3 with 5.6 cm size, after my pets scan they found my lytic lesion and sclerosis lesion on my spine with suv max 8 so they decided for biopsy , results shown negative , so at this point they just gonna keep in views by doing regular scaning, you know i just curious & worrisome because my suv max is 8..

    Sherry,

    SUV means standardized uptake value. It takes in consideration the patient size and the injected dose. Generally, a value above 2 is considered malignant.

    I don't think it is accurate to say a value above 2 is considered malignant.


    From the NIH:

    "Second, measured SUVs have a large degree of variability due to physical and biological sources of error, as well as inconsistent and non-optimized image acquisition, processing and analysis. More specifically, it has been repeatedly demonstrated that the use of SUV thresholds (e.g. SUV > 2.5), wherein a nodule or mass is characterized as benign or malignant using thresholds, is often invalid. As such, many benign infectious/inflammatory processes will have substantial FDG uptake with a high SUV value, and conversely, many indolent or slowly growing malignant processes may have minimal uptake, and low SUV values. This is not to say, however, that using SUV thresholds for diagnosis is not of any value. In circumstances where a nodule or tissue mass has uptake no greater than adjacent reference tissue and the pre-test likelihood of malignancy is low, the decision to develop a "watch and wait" strategy for management can often be safely adopted. In this situation, the very low false negative rate of negligible FDG uptake can assist with the decision to avoid unnecessary invasive procedures for tissue diagnosis. This has often been referred to as using FDG-PET as a "molecular imaging probe". As such, FDG PET/CT can assist in the decision to avoid unnecessary invasive tissue biopsy as well as guide such a procedure to a tissue location where a valid diagnostic biopsy sample can be obtained."
