RESUMO
BACKGROUND: According to the strongly negative grade D recommendation of the U.S. Preventive Services Task Force in 2012, the prostate-specific antigen (PSA) test was not only not recommended but was also warned against. As a result in the USA there was a stage shift towards more advanced tumor stages under the newly detected prostate cancers; however, in contrast to the highly questionable American PLCO study, the European ERSPC study showed a clear reduction in prostate cancer-related mortality. OBJECTIVE: In this patient cohort it was investigated whether the tumor stage distribution in curatively treated prostate cancer has significantly changed, whether this has an influence on the perioperative results and complication rates and how these changes could have occurred. MATERIAL AND METHODS: Patients after radical prostatectomy from 2008 to 2010 were compared to those from 2017. Demographic data, intraoperative courses, perioperative and postoperative complications and histopathological results were compared. RESULTS: A total of 1276 operations were analyzed. Preoperative PSA levels showed a significant increase in 2017 (10.5⯱ 13.4â¯ng/ml vs. 8.4⯱ 9.1â¯ng/ml, pâ¯= 0.032). The pathological staging revealed a 20% increase in T3 tumors (49.4% versus 29.0%, pâ¯< 0.001). Correspondingly, moderately and poorly differentiated cancers and therefore those with higher aggressiveness were significantly more frequent with 11.2% (pâ¯< 0.001) and 10.4% (pâ¯< 0.001), respectively. The number of patients with lymph node metastases at prostatectomy even increased fourfold (4.5% vs. 16.9%, pâ¯< 0.001). CONCLUSION: In the radical prostatectomy group, there was a shift to unfavorable and metastatic tumor stages. This negative trend seems largely to be caused by a lower acceptance of early detection by means of PSA determination.

A cross-sectional survey was carried out in Gedaref state, eastern Sudan to investigate the prevalence of positive leishmanin skin tests and environmental factors related to Leishmania donovani infection. A total of 3835 people living in 11 villages in 3 regions were screened. Soil types and tree densities were determined in 33 villages inhabited by 44 different tribes. The highest rates of positive skin tests were in Rahad region (33.9%), Atbara (21.6%) and Gedaref (10.6%), with an average of 21.1% for the state. Risk of infection by L. donovani varied significantly between different tribes. Higher densities of Acacia and Balanites spp. trees were in Masaleet villages, suggesting that the relatively high risk of L. donovani exposure in this tribe is due to environmental factors.
