Abstract
We present a case of prostate cancer (PC) developing in a hypogonadal patient with well-controlled type 1 diabetes. The purpose of reporting this case is to emphasize that regular prostate examinations and prostate-specific antigen (PSA) measurements should be preformed in the diabetic male, even though the incidence of PC is lower in this group of patients. In addition, these examinations and tests need to be preformed even in the hypogonadal patient with diabetes since the presence of a low serum testosterone (T) level does not preclude the development of PC. This is because the development of PC is not related to serum androgen levels but to the androgen levels within the prostate, and dihydrotestosterone (DHT) levels and not T levels within the prostate gland are responsible for the development of PC. In the hypogonadal male, intraprostatic DHT may be high since DHT can be formed from adrenal androgens, particularly androstenedione, through activation of 5α-reductase 2, which is the minority enzyme in the normal prostate but becomes the major enzyme in the formation and growth of PC.

Abstract
OBJECTIVES To estimate observed and relative survival of prostate cancer patients in sub-Saharan Africa (SSA) and to examine the influence of age, stage at diagnosis and the Human Development Index (HDI). PATIENTS AND METHODS In this comparative registry study, we selected a random sample of 1752 incident cases of malign prostatic neoplasm from 12 population-based cancer registries from 10 SSA countries, registered between 2005 and 2015. We analyzed the data using Kaplan-Meier and Ederer II methods to obtain outcome estimates and flexible Poisson regression modeling to calculate the excess hazards of death RESULTS: For the 1406 patients included in the survival analyses, 763 deaths occurred during 3614 person-years of observation. Of patients with known stage, 45.2% had stage IV disease, 31.2% stage III and only 23.6% stage I and II. The 1 and 5-year relative survival for the entire cohort was 78.0% (75.4-80.7) and 60.0% (55.7-64.6), while varying between the registries. Late presentation was associated with increased excess hazards and a 0.1 increase in the HDI was associated with a 20% lower excess hazard of death, while for age at diagnosis no association was found. CONCLUSIONS We found poor survival of SSA prostatic tumor patients, as well as high proportions of late stage presentation, which are associated with inferior outcome. This calls for investment in health-care systems and action regarding projects to raise awareness among the population to achieve earlier diagnosis and improve survival.

Abstract
Cutaneous metastasis is a rare event occurring most frequently in patients previously diagnosed with cancer. However, subungual metastases are even less frequent. The most common neoplasms associated with the latter are lung, kidney, and breast neoplasms. Lung cancer is the main cause of subungual metastases in the fingers, and genitourinary tract tumors are the main cause of subungual metastases in the toes. This is the first case report of an adenocarcinoma of the prostate with subungual metastasis.

Abstract
An immunohistochemical study on the cells proliferative activity by Ki-67 protein and localization of the matrix metalloproteinase-9 and the inhibitor of matrix metalloproteinase-1 was carried out at the benign prostatic hyperplasia (BPH) and the adenocarcinoma (AC) of different Gleason's grades. A significant decrease of the MMP-9 and TIMP-1 level in the AC of different gradations was observed. A moderate positive correlation between the Gleason score and cell proliferation Ki-67 index (rs = 0.674) and a moderate negative correlation with the level of such a score and expression of MMP-9 (rs = -0.660) was detected. A weak negative correlation exists also between the level of proliferative activity of secretory cells and the expression of MMP-9 by tumor cells (rs = -0.369). The invasive properties of AC cells that promote a degradation of the basal membrane and connective tissue in prostate may be explained by the imbalance between the MMP-9 and TIMP-1, which expression is significantly reduced in AC, in comparison with BPH.
