The landscape for advanced prostate cancer has significantly evolved over the past decade. However, there remains a notable lack of robust evidence across various facets of clinical practice. The Taiwan Urological Association organized the 2022 Taiwan Advanced Prostate Cancer Consensus Conference (TAPCCC) to address specific topics designed to augment existing guidelines. The TAPCCC 2022 questionnaire was designed based on the Advanced Prostate Cancer Consensus Conference 2022 held by the Advanced Prostate Cancer Society and tailored to regional characteristics and medical practice in Taiwan. The questionnaire involved 7 areas of advanced prostate cancer: high-risk and locally advanced prostate cancer, biochemical recurrence, management of metastatic hormone-sensitive prostate cancer, management of nonmetastatic castration-resistant prostate cancer, importance of lifestyle and prevention of complications in advanced prostate cancer, management of metastatic castration-resistant prostate cancer, and oligometastatic and oligoprogressive prostate cancer. The panel experts voted anonymously on 93 predefined questions before and after the conference following a modified Delphi process. A consensus was defined as ≥75% agreement of answer options and strong consensus was defined as ≥90% agreement of answer options. A total of 61 Taiwanese panel experts were involved. Of the 93 questions asked, 40 (43.0%) achieved consensus and 14 (15.1%) reached a strong consensus. In addition, 18 questions (19.4%) demonstrated a ≥75% agreement while combining answer options. The voting results were presented alongside the most recent guidelines and evidence found in the literature, a detailed report of which is included in Supplementary Materials, http://links.lww.com/URSC/A51. In conclusion, the TAPCCC 2022 successfully identified salient issues, and the consensus answer options arising from the conference merit thorough evaluation for integration into clinical practice. The voting results offer guidance for clinicians navigating the management of advanced prostate cancer, particularly in situations where there is a paucity of robust evidence. [ABSTRACT FROM AUTHOR]

The effect of telmisartan on prostate cancer DU145 cell survival and the underlying mechanism of apoptosis involving peroxisome proliferator-activated receptor (PPAR) pathway were investigated. Cultured DU145 cells were treated pharmacologically with telmisartan and GSK0660 (a PPAR-delta antagonist); or by RNA interference with siRNA of PPAR-delta. The treatment effects on cell survival were evaluated with cell viability assay, life and dead cell staining and flow cytometry. Western blot analysis for PPAR-delta protein expression was also performed. The results showed that telmisartan (0–80 µm) dose-dependently reduced DU145 cell survival. Flow cytometry demonstrated cancer cell cycle arrest with increase of sub-G1 phase. GSK0660 partially but significantly restored the telmisartan-treated cell viability. Similarly, siRNA of PPAR-delta significantly reversed the telmisartan-induced apoptosis. Western blot showed that telmisartan significantly increased DU145 cell PPAR-delta protein expression. Co-incubation with siRNA of PPAR-delta inhibited the telmisartan effect of PPAR-delta up-regulation. In conclusion, telmisartan induces prostate cancer DU145 cells apoptosis through the up-regulation of PPAR-delta protein expression. Pharmacological inhibition or genetic silencing of PPAR-delta activity can both reverse the telmisartan-induced apoptotic effect. Thus the PPAR-delta pathway might be a potential target for the treatment of prostate cancer. [ABSTRACT FROM AUTHOR]
