Prostate cancer is one of the leading causes of death in men all over the world. Treatment options such as androgen ablation therapy and cytotoxic agents have many undesirable side effects, narrow therapeutic windows, or other limitations. In this research, we have explored the effects of paeonol on prostate cancer and its mechanism of action. Our results have shown that paeonol reduced the viability of prostate cancer cells in a dose-dependent manner. The wound-healing assay, a surrogate marker of tumor metastasis, showed that the relative wound width of 10 µM group was less than that of 50 µM paeonol-treated cells. Besides, the results of the transwell assay also showed that the number of migrated cells was significantly lower after treatment with 50 µM paeonol compared to the 10 µM group. The Western blot results showed that paeonol treatment induced a decrease in the mesenchymal markers (vimentin and N-cadherin), while the epithelial marker (E-cadherin) increased in a dose-dependent manner suggesting that paeonol effectively inhibits the epithelial-mesenchymal transformation in PC3 cells. Furthermore, the expression of STAT3 and p-STAT3 was also decreased after paeonol treatment, which indicated that the STAT3 signaling pathway was inhibited by paeonol. To conclude, the results summarized in this paper suggest that paeonol could be a potential candidate in the treatment of prostate cancer.

Abstract Background Prostate cancer (PC) is a leading cause of death in older men. Androgen deprivation therapy (ADT) is considered the standard-of-care for men with locally advanced disease. However, continuous androgen ablation is associated with acute and long-term adverse effects and most patients will eventually develop castration-resistant PC (CRPC). The recent approval of three, second-generation androgen receptor inhibitors (ARIs), apalutamide, enzalutamide, and darolutamide, has transformed the treatment landscape of PC. Treatment with these second-generation ARIs have produced positive trends in metastasis-free survival, progression-free survival, and overall survival. For patients with non-metastatic CRPC, who are mainly asymptomatic from their disease, maintaining quality of life is a major objective when prescribing therapy. Polypharmacy for age-related comorbidities also is common in this population and may increase the potential for drug–drug interactions (DDIs). Method This review summarizes the multiple factors that may contribute to the therapeutic burden of patients with CRPC, including the interplay between age, comorbidities, concomitant medications, the use of ARIs, and financial distress. Conclusions As the treatment landscape in PC continues to rapidly evolve, consideration must be given to the balance between therapeutic benefits and potential treatment-emergent adverse events that may be further complicated by DDIs with concomitant medications. Patient-centered communication is a crucial aspect of alleviating this burden, and healthcare professionals (HCPs) may benefit from training in effective patient communication. HCPs should closely and frequently monitor patient treatment responses, in order to better understand symptom onset and exacerbation. Patients also should be encouraged to participate in exercise programs, and health information and support groups, which may assist them in preventing or mitigating certain determinants of the therapeutic burden associated with PC and its management.

Prostatic Atrophy

In this special issue of Endocrine-Related Cancer, we are celebrating the 80th anniversary of hormone ablation as treatment for metastatic prostate cancer. Our understanding has evolved from the observation that androgen withdrawal, either surgical or pharmacological, resulted in prostatic atrophy in animal models, to its application in patients, to investigation of the mysterious way in which prostate cancer escapes androgen dependence. We are now in an era of novel AR pathway inhibitors, combination of androgen ablation with chemotherapy, PARP inhibitors, immunotherapies, guided radiotherapy, and novel drug application based upon genetic testing of individual tumors. In this Anniversary Issue, we bring together a collection of eight reviews that cover not only the history of 80 years of progress after the initial identification of androgen ablation as an effective treatment of prostate cancer, but subsequent improvements in the understanding of the biology of the disease, development of novel treatment paradigms, resistance to those treatments and disease progression following that resistance.
