Abstract
Radical prostatectomy and external beam radiotherapy are recognized as comparable treatment options for localized prostate cancer. Previous studies of oncological outcomes of surgery versus radiotherapy have reported their comparability or possible superiority of surgery. However, the issue of which treatment is better remains controversial. Several factors make fair comparison of their outcomes difficult: different patient backgrounds caused by selection bias, different definitions of biochemical recurrence and different complication profiles between the treatment modalities. In 2016, the first large randomized controlled trial was published, which compared radical prostatectomy, external beam radiotherapy and active monitoring in localized prostate cancer. More recently, another study has reported comparative outcomes of robot-assisted radical prostatectomy and volumetric modulated arc therapy, as the leading surgery and radiotherapy techniques, respectively. Furthermore, there has been a trend toward combining external beam radiotherapy with brachytherapy boost, especially in patients with high-risk prostate cancer. This review summarizes the updated evidence on oncological outcomes of surgery versus external beam radiotherapy for localized prostate cancer.

Abstract
Histone lysine N-methyltransferase 2D (KMT2D), an important methyltransferase that is involved in the methylation of lysine 4 in histone H3 (H3K4) and related to the development of prostate cancer. Hypermethylation of H3K4 is shown in prostate cancer (PCa). However, KMT2D inhibitors have not yet been developed. This article aims to design small molecule inhibitors targeting KMT2D_SET to prevent PCa cell proliferation and migration. Twenty-four inhibitors were firstly designed according to a virtual screening of computers,and shown different degrees of binding to KMT2D_SET. Compounds 1 and 16 showed high binding affinities to KMT2D, with KD values of 147 ± 32.9 μM and 176 ± 37.9 μM, respectively. In addition, they exerted strong inhibitory activity against the PCa cell lines PC-3 and DU145, with IC50 values of 1.1 ± 0.06 μM, 1.5 ± 0.06 μM and 1.8 ± 0.1 μM, 2.3 ± 0.2 μM, respectively. Furthermore, these two compounds significantly suppressed the migration of PCa cells.
