Prostate cancer is a public health problem in Senegal. It is one of the most common cancers in men and can be detected early by Psa measurement and confirmed by the pathological study which specifies the histological type and evaluates the histoprognostic scores (Gleason and pTNM). We did not find any anatomopathological study highlighting a link between the Psa t rate and histoprognostic Gleason scores in Senegal. Objective: We carried out this work aimed at determining whether there is a correlation between the Psa t rate and the histoprognostic Gleason score, in our context. Methodology: This is a retrospective, descriptive and analytical study conducted from January 2013 to October 2021, based on histologically proven prostate cancer cases with a specified Psa level, diagnosed in the pathological anatomy and cytology laboratory of Aristide Le Dantec hospital. Results: We identified 654 cases of prostate cancer. The average age was 68.59 ± 5.8 years with extremes of 40 years to 92 years. More than half of our cohort presented a clinical stage T2c, i.e. 56.94%. The average prostate volume on ultrasound was 81.81 ± 66 cc. The median Psa t was 110.5 ng/ml, with extremes ranging from 2 ng/ml to 74,770 ng/ml. Prostatic adenocarcinoma was the only histological type found in our patients. There was a predominance of Gleason score 6 (PICU grade group 1) observed in 35.17% of patients. Well-differentiated cancers were predominant and represented 35.17%. There was a statistically significant positive correlation between Psa t level and Gleason score (Spearman’s Rho = 0.305, p = 0.000). Conclusion: This study shows that in the Senegalese population, in patients with prostate cancer, the higher the Psa t level rises above normal, the higher the Gleason score tends to be.

Introduction: Intraductal carcinoma is often associated with high-grade, high-stage adenocarcinoma. Its frequency is variable and it is considered a poor prognostic factor. In our context, when prostatic carcinoma is diagnosed, pathologists do not always report the presence of this anatomopathological entity. We therefore conducted a study to determine the epidemiological and anatomopathological profile of patients with this lesion in Dakar. Materials and Methods: This is a retrospective descriptive study covering a 1-year period from January to December 2022. It focused on cases of intraductal carcinoma diagnosed among prostatic carcinomas collected in the anatomopathology laboratories of Hôpital Général Idrissa Pouye (HOGIP) and Hôpital Militaire de Ouakam (HMO). It was based on archives of anatomopathological reports, blocks and slides. A total of 200 cases of prostatic carcinoma were collated and reviewed to identify those presenting with intraductal carcinoma according to the diagnostic criteria of Guo and Epstein. Results: 87 cases of intraductal carcinoma were found, representing 43.5% of prostatic carcinomas. The mean age was 71 years. Patients in their seventh decade were the most represented, i.e. 42.5%. The majority of samples examined were biopsies (72.4%). The mean Psa level was 965.91 ng/ml, with extremes ranging from 0.03 to 10,000 ng/ml. Histologically, 96.5% of cases (N = 84) were invasive prostatic carcinoma. Gleason score 8 (4 + 4) was the most common, accounting for 42.53% (N = 37). On average, the study found four (04) foci of intraductal carcinoma per specimen, with extremes ranging from 1 to 30. Dense cribriform architecture accounted for 78.16%, loose cribriform for 11.5%, solid for 8.04% and micropapillary for 2.3%. Six cases (6.9%) showed foci of comedonecrosis. The vast majority of radical prostatectomies (87.5%) were classified as pT3. Node invasion and perineural sheathing were observed in 12.5% and 52.32% of cases respectively. Conclusi

Introduction: Prostate cancer is the second most common cancer in men. The diagnosis is most often based on the prostate biopsies’ analysis and on histological criteria recognizable on standard coloring. In some cases, the use of immunohistochemistry is important. Objectives: This paper aims to specify the p63 phenotypic profile of lesions diagnosed benign, with minimal suspect foci, difficult to interpret, HGPIN (high grade intraepithelial neoplasia) and LGPIN (low-grade prostatic intraepithelial neoplasia) and evaluate the manual technique of p63 immunohistochemistry. Patients and Method: This was a retrospective, descriptive study of prostate biopsies recorded in the PAC service of the HALD from January 1st, 2018 to December 31st, 2018. It was completed by a manual immunohistochemical study of the blocks enrolled from November 19th to December 4th, 2020 in the PAC department of the HPD. The studied parameters were: registry number, age, clinical stage, prostate volume, Psa level, microscopic appearance and p63 immunohistochemical profile. Results: Our study included 60 prostate biopsies. The ages of our patients varied from 45 to 77 years, with an average of 64.2 years and a standard deviation of 6.2. The majority of patients were at clinical stage cT2b (33%) with a prostate volume varying between 33.15 and 169.4 cc. The minimum value of Psa in our series is 5 ng/ml, the maximum being 100 ng/ml with an average level of 24.1 ng/ml and a standard deviation of 21.2. Our series included 50 adenomyomatous hyperplasias, 7 adenomyomatous hyperplasias associated with chronic prostatitis, 2 HGPIN and 1 LGPIN. After re-reading we found 5 discordant cases, which corresponded to minimal suspect foci (kappa = 0.5098). The p63 marking was informative in 53 cases, i.e. 88%, and non-informative in 7 cases, i.e. 12%. Among the uninformative markings, 2 were due to lack of tissue adhesion to the slides. Among the informative markings, 11 were negative. p63 immunohistochemistry was
