AI Article Synopsis
- Prostate cancer can spread to uncommon sites like the rectal mucosa, which results in more advanced disease and a worse prognosis.
- A 65-year-old man had a PET/CT scan that showed intense PSMA uptake in areas including his prostate, bladder, and rectum.
- The imaging helped identify the rectal wall as a site of metastasis, indicating that PSMA PET/CT could be useful for detecting rare prostate cancer metastases early on.
Article Abstract
Prostate cancer metastasis to the rectal mucosa, a relatively rare metastatic site, leads to a higher clinical stage and poorer prognosis. A 65-year-old man with prostate cancer underwent 18 F-prostate-specific membrane antigen (PSMA) PET/CT for staging. Intense 18 F-PSMA uptake occurred at the primary lesion, bladder, adjacent seminal vesicle, and rectum. PET/CT imaging revealed increased homogeneous round activity of the rectal wall. The final diagnosis was prostate cancer metastasis to the rectal mucosa. This case suggested that 18 F-PSMA PET/CT may assist in locating rare metastases of prostate cancer, with potential value for early staging.

Coding Variants of the Genitourinary Development Gene Carry High Risk for Prostate Cancer.

Purpose: Considerable genetic heterogeneity is currently thought to underlie hereditary prostate cancer (HPC). Most families meeting criteria for HPC cannot be attributed to currently known pathogenic variants.
Methods: To discover pathogenic variants predisposing to prostate cancer, we conducted a familial case-control association study using both genome-wide single-allele and identity-by-descent analytic approaches.
Expression Patterns of DLL3 Across Neuroendocrine and Non-Neuroendocrine Neoplasms Reveal Broad Opportunities for Therapeutic Targeting.

Neuroendocrine neoplasms (NENs) encompass a diverse set of malignancies with limited precision therapy options. Recently, therapies targeting DLL3 have shown clinical efficacy in aggressive NENs, including small cell lung cancers and neuroendocrine prostate cancers. Given the continued development and expansion of DLL3-targeted therapies, we sought to characterize the expression of DLL3 and identify its clinical and molecular correlates across diverse neuroendocrine and non-neuroendocrine cancers.

Objective: This study aimed to investigate the influence of p16 immunohistochemical expression on the biochemical recurrence rate of pT2-pT3 prostate cancer.
Materials And Methods: A total of 488 pT2-pT3 stage prostate adenocarcinomas undergoing radical prostatectomy were included in this study. Following a review of Gleason classification and retrieval of sociodemographic and clinicopathological data, as well as the date of last consultation and biochemical recurrence, immunohistochemistry for p16 was performed.
CRM1 regulates androgen receptor stability and impacts DNA repair pathways in prostate cancer, independent of the androgen receptor.

Among the known nuclear exportins, CRM1 is the most studied prototype. Dysregulation of CRM1 occurs in many cancers, hence, understanding the role of CRM1 in cancer can help in developing synergistic therapeutics. The study investigates how CRM1 affects prostate cancer growth and survival.
