The impact of different radiotherapy modalities on the development and characteristics of second primary bladder cancers (BCa) and BCa-specific mortality (BCa-SM) remains unclear. Thus, we evaluated the incidence and biological behavior of subsequent BCa and related survival in patients who underwent radiation therapy for prostate cancer (PCa).

Impact of prostate cancer radiotherapy on the biological behavior and specific mortality of subsequent bladder cancer.

 Prostate cancer is the second leading cause of cancer-related deaths in Western countries. Most patients diagnosed with advanced prostate cancer can be treated with the main treatment: androgen deprivation therapy (ADT). The androgen receptor (AR) signaling axis plays a pivotal role in the progression of prostate cancer. However, most patients can ultimately progress to the castration-resistant prostate cancer (CRPC) stage within 2 years. At this stage, drugs targeting the AR signaling axis, including enzalutamide and abiraterone acetate, cannot prevent the progression of prostate cancer, thus predicting a poor prognosis. The molecular mechanism lies in the aberrant AR reactivation, which exhibits an adaptive response to ADT, such as the presence of AR splice variants. Thus, CRPC treatment remains a challenge.  In addition to the AR axis, a mechanism leading to this progression should be determined. The present study mainly compared palmitoylated proteins between androgen-treated LNCaP cells and non-treated LNCaP cells by palmitoylome profiling, to illustrate the changes at proteomic levels.  To screen the androgen-induced palmitoylated proteins, we conducted proteomic experiments using clickable palmitate probe (Alk-C16) between three individual pairs of androgen-treated and non-treated LNCaP cells.  We identified 4351 unique peptides corresponding to 835 proteins, among them a number of these identified proteins were palmitoylated proteins, particularly eIF3L. Androgen treatment significantly increased the palmitoylation level of eIF3L, an individual subunit of eIF3. As an initiation factor, eIF3L plays a pivotal role in the translation of mRNAs encoding growth-promoting proteins by enhancing translation rates, thus controlling cell proliferation.  In this study, we demonstrated that the regulation of eIF3L palmitoylation may provide new directions for the therapy of prostate cancer. Moreover, the increased level of androgen-induced eIF3L may be used as a biomarker for the diagnosis of early-stage prostate cancer.

Androgen upregulates the palmitoylation of eIF3L in human prostate LNCaP cells.

To assess the efficacy and safety of green-light laser photoselective vaporisation of the prostate (PVP) compared with transurethral resection of the prostate (TURP) for lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH).

Comparison of photoselective green light laser vaporisation versus traditional transurethral resection for benign prostate hyperplasia: an updated systematic review and meta-analysis of randomised controlled trials and prospective studies.

BACKGROUND Evidence directly evaluating the efficacy of tadalafil vs. tamsulosin for lower urinary tract symptoms (LUTS) secondary to benign prostate hyperplasia (BPH) is limited. We performed a meta-analysis of published studies to assess the comparative effectiveness of tadalafil vs. tamsulosin in treating LUTS suggestive of BPH. MATERIAL AND METHODS After performing a comprehensive publication search with PubMed, EMBASE, and Cochrane Controlled Trials Register using the search terms "tadalafil", "tamsulosin", "lower urinary tract symptoms", and "controlled", 335 articles were screened, out of which 7 randomized controlled trials published up to July 2019 were identified and included in this meta-analysis review. RESULTS From 335 screened articles, 7 studies (totalling 1601 patients) were finally included in our analysis. There was no statistically significant difference between tadalafil and tamsulosin in improving the clinical outcomes of total International Prostate Symptom Score (IPSS),voiding subscores, storage subscores, quality of life (QoL) scores, maximum flow rate (Qmax), and postvoid residual urine (PVR), but a statistically significant difference was observed in the International Index of Erectile Function scores (IIEF scores). CONCLUSIONS Tadalafil and tamsulosin have similar effects in managing LUTS secondary to BPH. Tadalafil is superior to tamsulosin in treating LUTS suggestive of BPH when associated with erectile dysfunction (ED).
