Hi all, apologies for the long post, hoping to give as much info as possible.
Background:
Diagnosis: Unfavorable int-risk prostate cancer (T2a, Gleason 4+3, PSA 5.2) (I spoke to a surgeon today who said it was T3a so now I am confused)
Age: 59
PSA 5.2 (H) 01/31/2024
PSA 4.4 (H) 11/06/2023
PSA 4.9 (H) 10/10/2023
PSA 2.8 10/22/2019
PSA 1.7 07/21/2017
PSA FREE 0.6 01/31/2024
PSA % FREE 11.5 (L) 01/31/2024
IMAGING:
4/26/24 PSMA PET: Impression
1. LOCAL TUMOR: Mild tracer activity in the left prostate.
2. REGIONAL NODAL DISEASE (N stage): No positive regional lymph nodes (miN0).
3. DISTANT METASTASIS (M stage): No distant metastasis (miM0).
Tracer avid axillary, iliac, obturator, and inguinal lymphadenopathy. While this is not consistent with metastatic prostate cancer, it is concerning for a secondary malignancy.
Narrative
PSMA-LIGAND PET/CT SKULL VERTEX TO MID THIGHS
** HISTORY **:
59 years old, newly diagnosed risk prostate carcinoma, with concerning for pelvic metastatic disease on CT. Initial treatment strategy.
** TECHNIQUE **:
RADIOPHARMACEUTICAL: F-18 DCFPyL (piflufolastat) 9.9 mCi IV
Tracer uptake time: 65 minutes
PET and low-dose, noncontrast CT (used for attenuation correction and anatomical localization; not optimized for visceral and vascular evaluation) images acquired from skull vertex to mid thighs. miN/M staging scheme reported as per E-PSMA standardized reporting guidelines v1.0 (Eur J Nucl Med Mol Imaging 2021; 48: 1626-38); miT-stage is generally not reported as this assessment may be unreliable on basis of PET/CT and would be more reliably assessed anatomically with mpMRI.
CTDI: 2.6 mGy; DLP: 26810 mGy-cm
COMPARISON: CT 4/5/2024, MR 2/27/2024
** FINDINGS **:
PROSTATE
Tracer-avid lesion focality: Unifocal, left.
Overall highest intensity of lesional tracer uptake in the prostate gland: SUVmax 2.9, visual uptake score = 1 (>/= blood pool, < liver intensity)
Seminal vesicle involvement: None clearly identified (though PET/CT may have lower detection sensitivity / accuracy than mpMRI).
Other:
REGIONAL LYMPH NODES
Internal iliac nodes: No tracer-avid nodes.
External iliac nodes: No tracer-avid nodes.
However, there are non-tracer avid iliac chain lymph nodes. The largest is a 15 mm right external iliac node on image 260.
Obturator nodes: No tracer-avid nodes.
However, there are non-tracer avid obturator lymph nodes. The largest is measures 10 mm, image 256.
Presacral nodes: No tracer-avid nodes.
Other pelvic nodes: No tracer-avid nodes.
DISTANT METASTASIS
Common iliac nodes: No tracer-avid nodes.
Retroperitoneal (para-aortic, aortocaval, precaval) nodes: No tracer-avid nodes.
However, there are non-tracer avid bilateral inguinal lymph nodes. The largest is a 14 mm, image 27.
Inguinofemoral nodes: No tracer-avid nodes.
Supradiaphragmatic nodes: No tracer-avid nodes.
However, there is bilateral non-tracer axillary lymphadenopathy, measuring up to 15 mm in diameter.
Bones: No tracer-avid or destructive osseous lesion.
Liver: No tracer-avid lesion.
Lungs: No tracer-avid nodule or mass.
OTHER FINDINGS
Vasculature: Limited evaluation without IV contrast. Coronary and aortic calcification. Normal abdominal aortic diameter (<3cm)
4/5/24 bone scan: No scintigraphic evidence of osseous metastatic disease.
4/5/24 CT a/p: Bilateral inguinal and external iliac lymphadenopathy, concerning for metastatic disease

-PERINEURAL INVASION
2/27/24 MRI prostate: 1.6cm PI-RADS 5 lesion in left mid and apical peripheral zone; vol 19.2cc; Nonspecific inguinal lymph nodes measuring up to 1.4 cm on the right. 1 cm low left pelvic sidewall lymph node. 9 mm right pelvic sidewall lymph node
The radiologist suggested 3 markers to be inserted with 20 visits of external beam, also mentioned something else that I do not recall the name of but 5 visits with more radiation each time, both combined with Lupron for 6 months.
The surgeon suggested surgery non-nerve sparing on the left as there was PNI but could spare the right with pelvic lymph node dissection.
Of course, I have all this lymphadenopathy and they mentioned a secondary malignancy which is just great to add on top of what I was originally stressed out about. Has anyone ever had this arise?
Would love to hear your thoughts/ suggestions/ advice on the next steps moving forward.
