Curiosity: ChatGPT and my PET scan

Ok, take it as a curious/fun thing to ask chat gpt, not as a real medical consult.

I have given my PET scan results (in Italian) to chat gpt, to see if they were in line with my oncologist's opinion. I asked it to read the results and tell me if they were very negative, negative, neutral, positive or very positive.

The answer was between positive and very positive, with a chance of becoming definitely very positive because I still have 2 rounds of chemo.

My oncologist was more on positive and not very positive, but he was happy to have good results following the triplet therapy.

I should try this. I had a Pylarify scan performed after my BCR. I then got a second opinion on treatment from an MO at MSK. MSK also reviewed and provided a report. They were similar in some respects and different in others.

It be interesting what gets spit out ..garbage in garbage out.

Well, I was curious to see the results from dr chat gpt but it's just curiosity...and ok, sometimes when I encounter a term I am not sure about, I ask chat gpt instead of googling it, makes me save 30 seconds :-P

By "negative," I guess you mean "bad", not that the results were negative (which means the PET scan found nothing)? But did ChatGPT also confuse the meaning of the words?

nah, it did not, I was referring to positive response to treatment

This PSMA PET scan report describes the findings in a patient, likely with prostate cancer given the mention of the prostate and surrounding structures. Let's break down the findings:

Prostate and Seminal Vesicle Area: There is a reduction in the extent of the area showing increased uptake (hyperfixation) in the prostate tissue and the apex of the seminal vesicles. This suggests a positive response to treatment, as the affected areas are shrinking.

Lymph Nodes (Adenopathies) in the Pelvic and Retroperitoneal Areas: There's a marked reduction in both size and number of hyperfixing lymph nodes previously described in the bilateral pelvic area (maximum axis now about 2.3 cm vs 4 cm before) and retroperitoneal area (maximum axis now pericentimetric vs 2 cm before). Most of these lymph nodes also show a reduction in the uptake gradient (a measure of how much radiotracer they absorb). The most active one is in the right external iliac area with a stable maximum SUV (Standardized Uptake Value) of 25; the others show a maximum SUV of 13 compared to 27 previously. This also indicates a response to treatment.

Bone Lesions: The hyperfixing bone lesions (areas of increased uptake, indicative of cancer spread) located at the left acetabulum, sacrococcygeal junction, left iliac wing, right side of the L4 vertebral body, and the right third posterior rib arch have reduced uptake gradients. This suggests that these lesions are responding to treatment.

Ileopubic Branch Lesion: There's a lesion at the ileopubic branch on the left side that remains unchanged in terms of its increased uptake. This might indicate that this particular lesion is not responding to treatment as well as the others or could be stable disease.

Rest of the Body: The distribution of the radiotracer in the remaining examined body districts is regular, suggesting no abnormal uptake in other areas.

Overall, this report generally indicates a positive response to treatment, with a reduction in the size and activity of most of the cancerous lesions in the prostate, lymph nodes, and bones. However, the stable lesion at the ileopubic branch may need further evaluation or a different therapeutic approach.

Considering that there are still two rounds of Docetaxel chemotherapy remaining, the current PSMA PET scan results can be viewed in an even more positive light.

You will cause less confusion in discussing tests if you reserve the words positive to mean it found something, and negative to mean it found nothing. Prognosis can be "good" or "bad."

Just copy the medical test results verbatim in chat GPT and ask it to tell you what it means in layman's terms. Your question is confusing the way you've worded it. Does Chat think you meant outcomes or tumor detection?

Maxone73 in reply to swwags

No, it interpreted my question correctly as I referred to positive outcomes not to positive or negative results of the test

“Overall, this report generally indicates a positive response to treatment, with a reduction in the size and activity of most of the cancerous lesions in the prostate, lymph nodes, and bones”

you left off the word "outcomes" in your initial post sir.

I am now using chatgpt to write my computer programs :) it is amazing. i no longer need to remember arcane syntax or try to find old programs to copy from. i no longer need to struggle with writing regex. of course full programs never work quite right but i am now doing programming that i had given up on in my old age. i have written some programs with the help of chat that i would never have been able to finish on my own.

i am wondering what you submitted to chat, was it the narrative report already analyzed by a radiologist? i do not know of any way to submit an actual scan?

Well for small parts you cannot beat it especially when you are required to use a language you don’t know. I would not write an entire routine with it, tried but there is always something wrong. But technically a software engineer should use 2/3 of the time to do a top down analysis and break the code into single function atomic functions and then program bottom up, creating small pieces of code interlocked. Even if clients nowadays want to see something graphical asap! Oh well! To get back to your question no, a radiologist wrote the report comparing it with the pet scan I had 3 months ago. I have then fed it to chatgpt and asked to break it down point by point.

here is a gpt prompt that I use for my mri/ct/etc reports. Attach or paste a copy of the report and run this prompt. You can also ask questions about the results:

Expert-Level Analysis Prompt for Prostate Cancer Radiologist Reports

“Assume the role of an expert in interpreting radiologist reports for MRI and CT scans pertaining to prostate cancer. Utilize your comprehensive knowledge base to read and analyze the attached radiologist reports. Provide a detailed summary of each report, focusing on the following aspects:

1. Type of Scan: Identify whether the report is for an MRI or a CT scan, and note any specific techniques or contrasts used.

2. Findings: Elaborate on the key findings from the reports, especially concerning the prostate gland. Include details about the size, location, and characteristics of any lesions or abnormalities noted.

3. Comparative Analysis: If previous scan reports are included, compare the current findings with the past scans to identify any changes or progression in the condition.

4. Radiologist’s Impression: Summarize the radiologist’s conclusions or interpretations, particularly any recommendations or concerns raised.

5. Potential Clinical Implications: Based on the findings, discuss the potential clinical implications or considerations that might be relevant for the treatment or management of prostate cancer.

6. Areas for Further Investigation or Clarification: Highlight any areas in the reports that might require further investigation or clarification from a medical professional.

Conclude your summary with a brief overview of the overall condition as presented in the reports, keeping in mind the importance of accuracy and attention to detail in your analysis.”

One note: I never make a decision based just on these responses. Always verify since GPT can and does get things wrong

I’m just curious. Did you use the free ChatGPT or the paid version?

Strange.......... I just entered my ex-wife's name on ChatGPT and the system responded by cursing me out and then shut down....... I suspect it really works....

Note: I wish to offer my apologies if I offended anyone regarding my so-called humor about "race" or "misogyny". To me, humor is boundless and since we entered this word crying, I thought it would be a good idea to exit laughing.

Good Luck, Good Health and Good Humor.
