Du XL, Gao D, Li Z. Incidence trends in prostate cancer among men in the United States from 2000 to 2020 by race and ethnicity, age and tumor stage. Front Oncol 2023; 13:1292577. [PMID: 38098506 PMCID: PMC10720073 DOI: 10.3389/fonc.2023.1292577] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2023] [Accepted: 11/15/2023] [Indexed: 12/17/2023] Open
Abstract
Purpose To explore whether prostate cancer incidence trends from 2000 to 2020 in the United States differed by race and ethnicity, age and tumor stage; to explore racial differences in prostate cancer incidence change due to the impact of COVID-19 pandemic lockdown in 2020; and to determine if there is any high-risk population that can be targeted for prevention. Methods We identified 1,098,349 men who were diagnosed with incident prostate cancer at age ≥20 in 2000-2020 in 17 registries of the Surveillance, Epidemiology, and End Results (SEER) program in the United States; of whom, 778,437 were non-Hispanic whites, 155,111 non-Hispanic blacks, 4,200 American Indians and Alaska Natives (AIAN), 55,267 non-Hispanic Asians/Pacific Islanders, and 105,334 Hispanics. Results Age-adjusted incidence rate of prostate cancer was the highest in blacks (302.6 cases per 100,000 men), followed by whites (186.6), Hispanics (153.2), AIAN (108.5), and Asians (104.9). Age-adjusted prostate cancer incidence rates dramatically decreased from 2000 to 2013 for all ethnic men. However, age-adjusted prostate cancer incidence rates increased from 2014 to 2020, in which the increasing incidence trend looked sharper in blacks and whites, flatter in Asians, and leveled in AIAN and Hispanics. Among men with local or regional stages across all years, prostate cancer incidence rate was significantly higher in blacks, but significantly lower in Hispanics, AIAN, and Asians as compared to whites. Among men in 2007-2013, the risk of distant stage prostate cancer was statistically significantly elevated in blacks (rate-ratio: 2.22, 95% CI: 2.06-2.38) and Hispanics (1.16, 1.06-1.25), not significantly different in AIAN (1.30, 0.92-1.76), but still significantly lower in Asians (0.73, 0.66-0.82) as compared to whites. There was a drop of prostate cancer incidence from 2019 to 2020 likely due to the impact of COVID-19 pandemic lockdown on the access to medical care in 2020. Overall prostate cancer incidence rate decreased by 40.4 cases per 100,000 population from 277.4 in 2019 to 237.0 in 2020 for blacks, 20.9 from 164.2 to 143.3 for whites, 16.8 from 124.8 to 108.0 for Hispanics, 14.9 from 101.7 to 86.8 for AIAN, and 12.6 from 88.4 to 75.8 for Asians. Conclusion The decreasing trend of prostate cancer incidence from 2000 to 2013 was statistically significant for all ethnic men. There was an increasing prostate cancer incidence from 2014 to 2020. Age-adjusted incidence rate of prostate cancer was the highest in blacks, followed by whites, Hispanics, AIAN, and Asians, regardless of age groups, tumor stages, and time periods. There will also be a need to monitor and investigate the prostate cancer incidence trend during and after COVID-19 pandemic season.

Chlordecone-contaminated epilithic biofilms show increased adsorption capacities. THE SCIENCE OF THE TOTAL ENVIRONMENT 2022; 825:153942. [PMID: 35189234 DOI: 10.1016/j.scitotenv.2022.153942] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/05/2021] [Revised: 02/11/2022] [Accepted: 02/13/2022] [Indexed: 06/14/2023]
Abstract
The rivers of Guadeloupe and Martinique (French West Indies) show high levels of chlordecone (CLD) contamination. This persistent molecule has a dramatic impact on both aquatic ecosystems and human health. In these rivers, epilithic biofilms are the main endogenous primary producers and represent a central food source for fish and crustaceans. Recently, their viscoelastic properties have been shown to be effective in bio-assessing pollution in tropical environments. As these properties are closely related to the biochemical composition of the biofilms, biochemical (fatty acids, pigments, extracellular polymeric substances (EPS) monosaccharides) and molecular markers (T-RFLP fingerprints of bacteria, archaea and eukaryotes) were investigated. Strong links between CLD pollution and both biofilm biochemistry and microbial community composition were found. In particular, high levels of CLD were linked with modified exo-polysaccharides corresponding to carbohydrates with enhanced adsorption and adhesion properties. The observed change probably resulted from a preferential interaction between CLD and sugars and/or a differential microbial secretion of EPS in response to the pollutant. These changes were expected to impact viscoelastic properties of epilithic biofilms highlighting the effect of CLD pollution on biofilm EPS matrix. They also suggested that microorganisms implement a CLD scavenging strategy, providing new insights on the role of EPS in the adaptation of microorganisms to CLD-polluted environments.

Abstract
Cancer causes a fifth of deaths in the Caribbean region and its incidence is increasing. Incidence and mortality patterns of cancer in the Caribbean reflect globally widespread epidemiological transitions, and show cancer profiles that are unique to the region. Providing comprehensive and locally responsive cancer care is particularly challenging in the Caribbean because of the geographical spread of the islands, the frequently under-resourced health-care systems, and the absence of a cohesive approach to cancer control. In many Caribbean countries and territories, cancer surveillance systems are poorly developed, advanced disease presentations are commonplace, and access to cancer screening, diagnostics, and treatment is often suboptimal, with many patients with cancer seeking treatment abroad. Capacity building across the cancer-control continuum in the region is urgently needed and can be accomplished through collaborative efforts and increased investment in health care and cancer control.

Abstract
Although research has reported that prostate cancer (PCa) incidence and mortality rates are among the highest for African Americans, the data is inconclusive regarding PCa rates in native African men, Black men residing in other countries, and men in Asia, Europe, and the Americas. Data reveals that prostate-specific antigen (PSA) testing and disease incidence have risen significantly in developing and Asian countries, and PCa has become one of the leading male cancers in many of those nations. The objective of this study was to review published peer-reviewed studies that address PCa in different regions of the world to get a better understanding of how PCa incidence, prevalence, detection, and mortality are influenced by race, ethnicity, and geography. A secondary goal was to compare PCa data from various world regions to contextualize how disproportionate the incidence and mortality rates are among men from the African diaspora versus men of European, Hispanic, and Asian descent, as well as to highlight the need for more robust screening and treatment guidelines in developing countries. There are differences in incidence and mortality rates between men of African, Asian, Hispanic, and European ancestry, confirming the involvement of genetic factors. However, differences between men of the same race and ethnicity who live in different countries suggest that environmental factors may also be implicated. Availability and access to diagnostic and health-care services as well as recommendations regarding PCa testing vary from country to country and contribute to the variability in incidence and mortality rates.

Abstract
Prostate cancer is one of the leading causes of death in men aged 40 to 55. Genistein isoflavone (4', 5', 7-trihydroxyisoflavone) is a dietary phytochemical with demonstrated anti-tumour activities in a variety of cancers. Topotecan Hydrochloride (Hycamtin) is an FDA-approved chemotherapy drug, primarily used for secondary treatment of ovarian, cervical and small cell lung cancers. This study was to demonstrate the potential anticancer efficacy of genistein-topotecan combination in LNCaP prostate cancer cells and the mechanism of the combination treatment. The LNCaP cells were grown in complete RPMI medium, and cultured at 37°C, 5% CO(2) for 24-48 hrs to achieve 70-90% confluency. The cells were treated with varying concentrations of genistein, topotecan and genistein-topotecan combination and incubated for 24 hrs. The treated cells were assayed for (i) post-treatment sensitivity using MTT assay and DNA fragmentation, (ii) treatment-induced apoptosis using caspase-3 and -9 binding assays and (iii) treatment-induced ROS generation levels. The overall data indicated that (i) both genistein and topotecan induce cellular death in LNCaP cells, (ii) genistein-topotecan combination was significantly more efficacious in reducing LNCaP cell viability compared with either genistein or topotecan alone, (iii) in all cases, cell death was primarily through apoptosis, via the activation of caspase-3 and -9, which are involved in the intrinsic pathway, (iv) ROS generation levels increased significantly with the genistein-topotecan combination treatment. Treatments involving genistein-topotecan combination may prove to be an attractive alternative phytotherapy or adjuvant therapy for prostate cancer.
