Prostate cancer (PCa) and type two diabetes mellitus (T2DM) are both increasing prevalent conditions and often occur concurrently. However, the relationship between the two is more complex than just two prevalent conditions co-existing. This review systematically explores the literature around the interplay between the two conditions. It covers the impact of pre-existing T2DM on PCa incidence, grade and stage, as well as exploring the impact of T2DM on PCa outcomes and mortality and the interaction between T2DM and PCa treatments...

Androgen receptor is the major driver of and testosterone the natural growth factor of prostate cancer (PC). Studies exploring the relationship among circulating testosterone levels, PC aggressiveness, and patient prognosis showed contradictory results. We performed a comprehensive literature search for studies reporting the independent relationship between serum testosterone and prognosis of PC patients. Meta-analyses using random effects models were conducted to estimate pooled hazard ratios (HRs) and 95% confidence intervals (CIs)...

BACKGROUND: After radical cystoprostatectomy (RC), postoperative erectile dysfunction (ED) is a common consequence with multiple contributing etiologies. The inflatable penile prosthesis (IPP) offers patients a definitive treatment option when ED is refractory to medical therapies. Because of the hostile postoperative anatomy of these patients, a careful surgical approach is necessary for successful outcomes and to avoid adjacent organ injury. To date, there is no series describing the outcomes of 3-piece IPP placement in patients with urinary diversions...

BACKGROUND: Tumor cells may be expressed as a result of oxidative stress. The extent of oxidative stress correlates with aggressive and metastatic potency of cancer. OBJECTIVE: One simple way to control prostate cancer is through chemoprevention which refers to the administration of natural or synthetic agents to block, reverse, or delay the process of carcinogenesis. The most chemopreventive agents are antioxidants in the nature. METHODS: In this review, we summarized the effects of dietary antioxidants with a focus on their molecular mechanisms and possible roles in the treatment of prostate cancer cells...

The human genome is 'pervasively transcribed' leading to a complex array of non-coding RNAs (ncRNAs) that far outnumber coding mRNAs. ncRNAs have regulatory roles in transcription and post-transcriptional processes as well numerous cellular functions that remain to be fully described. Best characterized of the 'expanding universe' of ncRNAs are the ~ 22 nucleotide microRNAs (miRNAs) that base-pair to target mRNA's 3' untranslated region within the RNA-induced silencing complex (RISC) and block translation and may stimulate mRNA transcript degradation...

Over 90% of prostate cancers over-express prostate specific membrane antigen (PSMA) and these tumor cells may be accurately targeted for diagnosis by 68 Ga-PSMA-positron emission tomography/computed tomography ( 68 Ga-PSMA-PET/CT) imaging. This novel molecular imaging modality appears clinically to have superseded CT, and appears superior to MR imaging, for the detection of metastatic disease. 68 Ga-PSMA PET/CT has the ability to reliably stage prostate cancer at presentation and can help inform an optimal treatment approach...

Metastases to the pancreas account for less than 5 percent of all malignancies affecting the pancreas. The most common secondary malignancy of the pancreas is renal cell carcinoma. We report a patient presented with abdominal pain and weight loss. Computed tomography (CT) imaging showed pancreatic head mass. Biopsy from the mass showed prostate metastasis after 13 years from radical prostatectomy and Leuprolide therapy. This case demonstrates a rare location for prostate metastasis which was the pancreas. To our knowledge there are only six cases reported in literature...

Background: Androgen deprivation therapy (ADT) with luteinizing hormone-releasing hormone (LHRH) agonists is well established for the treatment of men with metastatic prostate cancer. As clear differences in efficacy, safety, or tolerability between the available LHRH agonists are lacking, the healthcare management team needs to look to practical differences between the formulations when selecting therapy for their patients. Moreover, as the economic burden of prostate cancer rises alongside earlier diagnosis and improved survival, the possibility for cost savings by using products with specific features is growing in importance...
