Introduction & Objective: Prostatic carcinoma is the most common malignancy throughout the world among the males over middle age and the second leading cause of cancer-related deaths in western countries. The currently most established prognostic factors in prostatic carcinoma are histological grade (Gleason system) and tumor stage .Various new prognostic factors that have been suggested to pro...
Endogenous androgens have been suggested as determinants of risk of prostatic cancer. To examine this possibility, baseline sex hormone levels were measured in 1008 men ages 40-79 years who had been followed for 14 years. There were 31 incident cases of prostatic cancer and 26 identified from death certificates with unknown dates of diagnosis. In this study, total testosterone, estrone, estradi...

INTRODUCTION: Although accurate segmentation of the prostatic subregions is a crucial step for prostate cancer diagnosis, it remains challenge. OBJECTIVES: To propose deep learning (DL)-based cropping pipeline to improve performance DL networks segmenting prostate’s periphe
Prostate cancer is one of the most important malignancies in men. In old men the frequency of prostate cancer at necroscopy has been reported to exceed 40%. Dogs are the only large mammals other than humans with a significant incidence of spontaneous prostate cancer. Adenocarcinoma, transitional cell carcinoma and undifferentiated carcinoma are the most common histological type but the precise ...
To investigate whether prostatic calculi might influence the urinary retention (UR) probability, the quality of life (QOL) and the positive rate of cancer after prostate biopsy in middle-aged and old male with PSA higher than normal. This study comprised a retrospective analysis of data from 685 patients (prostatic calculi group 325 VS non-prostatic calculi group 360), those who had undergone t...
Background: Numerous studies confirmed that significant decrease in tissue decorin (DCN) expression is associated to tumor progression and metastasis in certain types of cancer including prostate cancer (PC). However, the potential prognostic value of tissue DCN in PC has not yet been investigated. Methods: A total number of 40 PC and 42 patients with benign prostatic hyperplasia (BPH) were inv...
Male breast cancer is uncommon, accounting for less than 1% of all breast cancers. Carcinoma metastatic to the male breast is also unusual, with metastatic prostatic carcinoma being among the most common primary sites from which such tumours derive. Metastatic prostatic cancer and primary breast cancer may be histologically indistinguishable without immunohistochemistry because both often infil...
Prostate cancer development is associated with hyperactive androgen signaling. However, the molecular link between androgen receptor (AR) function and humoral factors remains elusive. A prostate cancer mouse model was generated by selectively mutating the AR threonine 877 into alanine in prostatic epithelial cells through Cre-ERT2-mediated targeted somatic mutagenesis. Such AR point mutant mice...
