Prostate cancer is the second most common and the fifth leading cause of death by cancer in men worldwide now. The failure of androgen deprivation therapy (ADT) for prostate cancer caused by activated androgen receptor (AR) signaling pathways mostly found. The role of AR in growth and progression of prostate cancer is still unclear. Analysis of AR expression in prostate cancer has never been done in West Sumatera. This study aims to determine AR expression of prostate cancer and correlate with Gleason score and perineural invasion. A total of 56 prostate cancer from department of anatomical pathology in West Sumatera. Hematoxylin and eosin (HE) stained slides and paraffin blocks were retrieved. Slides of all cases were evaluated to review Gleason score, histopathological grading, WHO grade group based on ISUP 2014/WHO 2016 and perineural invasion. Androgen receptor immunohistochemistry (IHC) was applied on all cases. High AR expression was the mostly found (51,79%). The mostly prostate cancer is Gleason score 9 (44,64%), histopathological grading poorly differentiated/undifferentiated (76,78%), WHO grade group 5 (48,21%). Perineural invasion was noted in 39,29%. There was significant statistical correlation between AR expression and Gleason score, but no significant correlation with perineural invasion. AR expression is the important marker of prostate cancer progression.

Introduction: Prostate cancer is gradually reaching a very high incidence in Africa, especially in the Sub-Saharan region. Understanding the dynamics in occurrence of the disorder is one approach to developing effective public health programmes and interventions that will help curb the rising incidence. Objective: This study was aimed at providing comprehensive and credible data on prostate cancer by assessing the incidence, trend and presentation in the Brong Ahafo Region of Ghana. We sought to provide region-specific hardcore data that will help to assess the issue and provide remedies. Methodology: All prostate disease cases recorded from the year 2009 to 2018 were retrospectively reviewed. Subjects from 40 years and above were eligible for screening. Diagnostic and screening tools for prostate cancer at the study site include family history, serum prostate specific antigen (PSA) test, digital rectal examination, urological ultrasound scan and histopathology (biopsy). Age, PSA values and year of screening/diagnosis were also retrieved from patient folders for the study. Histological findings and parameters considered in the study included diagnosis, carcinoma grading, perineural invasion (PNI) and percentage of affected tissues (%TA). Results: Prostate cancer cases were 369, representing 36.4% of the 1,014 prostate diseases studied. The highest annual incidence was recorded in 2014 with 51 cases (13.8%). The ages of patients ranged from 46 to 101 years with a modal age range of 70 - 79 years and a mean ± SD of 72.2 ± 9.8. The mean PSA value recorded was 37.1ng/ml (±107.3) with predominance in the 11 - 20.9 ng/ml range. Majority of Group Grade 2-5 (79%) constituted progressive prostate cancer. There was no significant correlation (p = 0.091) between grade of prostate cancer and perineural invasion. Conclusion: There is a high incidence of prostate cancer in the Brong Ahafo Region of Ghana (32 per 100,000), predominantly advanced prostatic carcinoma. Reported cases also show high %TA (38.7%) and PNI (38.0%). Early screening for prostate diseases should be encouraged to avoid progression to advanced stage and public health interventions are needed to address some of these issues.
