Objectives: To determine the incidence and characteristics of prostate cancer in men with spinal cord injury (SCI). Little is known about the characteristics of prostate cancer in men with SCI, because prostate cancer screening is not aggressively performed in this population.
Methods: In one fiscal year, 648 men with SCI older than age 50 years were actively enrolled with the SCI service, 20,949 able-bodied men older than age 50 years were actively enrolled in the outpatient clinic database, and 945 patients with prostate cancer were in the cancer registry at our facility. These three databases were cross-referenced for prostate cancer diagnosis and stage and compared with the presence of SCI.
Results: Of the 648 patients with SCI, 12 patients with a prostate cancer diagnosis that preceded their injury were excluded. Of the remaining 636 patients, 11 (1.7%) had been diagnosed with prostate cancer since their injury. In contrast, of the 20,949 able-bodied men older than age 50 years seen at our facility in fiscal year 1999, 919 (4.4%) had prostate cancer. Of the patients with SCI and prostate cancer, 7 (63.6%) had locally advanced (Stage T3) or metastatic prostate cancer compared with 267 (29.1%) in the able-bodied population (P = 0.012).
Conclusions: Although the proportion of patients with a prostate cancer diagnosis was greater in the able-bodied patients, the prostate cancer detected in the patients with SCI tended to be of a more advanced stage and grade. The difference was likely a result of the decreased use of prostate cancer screening in this population.

The superiority of prostate-specific membrane antigen (PSMA) positron emission tomography (PET) over conventional staging methods such as computed tomography (CT) and bone scintigraphy has now been demonstrated for almost all clinical stages of prostate cancer. In primary diagnostics, PSMA-PET/CT is therefore the new standard for risk-adapted whole-body staging. At the same time, PSMA-PET/CT provides a new risk-based classification for predicting overall survival across all early and late stages of the disease.

Purpose To assess the impact of scanner manufacturer and scan protocol on the performance of deep learning models to classify prostate cancer (PCa) aggressiveness on biparametric MRI (bpMRI). Materials and Methods In this retrospective study, 5,478 cases from ProstateNet, a PCa bpMRI dataset with examinations from 13 centers, were used to develop five deep learning (DL) models to predict PCa aggressiveness with minimal lesion information and test how using data from different subgroups-scanner manufacturers and endorectal coil (ERC) use (Siemens, Philips, GE with and without ERC and the full dataset)-impacts model performance. Performance was assessed using the area under the receiver operating characteristic curve (AUC).

Orchidectomy and estrogenization of the male represent a procedure that is applicable in sex reassignment or in prostate cancer therapy. This approach has an influence on the hypothalamic-pituitary-adrenal axis and thus affects cardiovascular function and metabolism. We utilized orchidectomized rats to evaluate the effects of estradiol on the structure and hormonal output of the adrenal gland.

Objective: To assess the association between prostate-specific antigen (PSA) density (PSAD) and prostate cancer mortality after a benign result on systematic transrectal ultrasonography (TRUS)-guided prostate biopsy.
Patients And Methods: This retrospective study used data from the Finnish Randomised Study of Screening for Prostate Cancer (FinRSPC) collected between 1996 and 2020. We identified men aged 55-71 years randomised to the screening arm with PSA ≥4.

Patient stratification remains a challenge for optimal treatment of prostate cancer (PCa). This clinical heterogeneity implies intra-tumoural heterogeneity, with different prostate epithelial cell subtypes not all targeted by current treatments. We reported that such cell subtypes are traceable in liquid biopsies through representative transcripts.
