BACKGROUND: The International Agency for Research on Cancer (IARC) Monographs program assembles expert working groups who publish a critical review and evaluation of data on agents of interest. These comprehensive reviews provide a unique opportunity to identify research needs to address classification uncertainties. A multidisciplinary expert review and workshop held in 2009 identified research gaps and needs for 20 priority occupational chemicals, metals, dusts, and physical agents, with the goal of stimulating advances in epidemiological studies of cancer and carcinogen mechanisms. Overarching issues were also described. OBJECTIVES: In this commentary we review the current status of the evidence for the 20 priority agents identified in 2009. We examine whether identified Research Recommendations for each agent were addressed and their potential impact on resolving classification uncertainties. METHODS: We reviewed the IARC classifications of each of the 20 priority agents and identified major new epidemiological and human mechanistic studies published since the last evaluation. Information sources were either the published Monograph for agents that have been reevaluated or, for agents not yet reevaluated, Advisory Group reports and literature searches. Findings are described in view of recent methodological developments in Monographs evidence evaluation processes. DISCUSSION: The majority of the 20 priority agents were reevaluated by IARC since 2009. The overall carcinogen classifications of 9 agents advanced, and new cancer sites with either “sufficient” or “limited” evidence of carcinogenicity were also identified for 9 agents. Examination of published findings revealed whether evidence gaps and Research Recommendations have been addressed and highlighted remaining uncertainties. During the past decade, new research addressed a range of the 2009 recommendations and supported updated classifications for priority agents. This supports future efforts to systematically apply findings of Monograph reviews to identify research gaps and priorities relevant to evaluation criteria established in the updated IARC Monograph Preamble.

Context.--The incidence of prostate cancer with Gleason scores 2 through 4 has been decreasing for decades, largely because of evolving criteria for Gleason scores, including the 2005 International Society of Urological Pathology recommendation that scores of 2 through 4 should rarely, if ever, be diagnosed based on needle biopsy. Whether trends in assigning Gleason scores 2 through 4 vary by facility type and patient characteristics is unknown. Objective.--To assess trends in prostate cancer grading among various categories of treatment facilities. Design.--Analyses of National Cancer Database records from 1990 through 2013 for 434 612 prostate cancers diagnosed by core needle biopsy, including multivariable regression for 106 331 patients with clinical T1c disease diagnosed from 2004 through 2013. Results.--The proportion of prostate core needle biopsies with Gleason scores 2 through 4 declined from 11 476 of 53 850 (21.3%) (1990-1994) to 96 of 43 566 (0.2%) (2010-2013). The proportions of American Joint Committee on Cancer category T1c needle biopsies assigned Gleason scores 2 through 4 were 416 of 12 796 (3.3%) and 9 of 7194 (0.1%) during 2004 and 2013, respectively. Declines occurred earliest at National Cancer Institute--designated programs and latest at community programs. A multivariable logistic model adjusting for patient demographic and clinical variables and restricted to T1c cancers diagnosed in needle biopsies from 2004 through 2013 showed that facility type is independently associated with the likelihood of cancers in such specimens being assigned Gleason scores of 2 through 4, with community centers having a statistically significant odds ratio of 5.99 relative to National Cancer Institute-designated centers. Conclusions.--These results strongly suggest differences in Gleason grading by pathologists practicing in different facility categories and variations in their promptness of adopting International Society of Urological Pathology recommendations. (Arch Pathol Lab Med. 2017;141:1686-1696; doi: 10.5858/arpa.2016-0611-OA), Histologic grade is a valuable factor used in assessing prognosis and selecting treatment for patients with many forms of cancer, and this is especially true regarding the Gleason score for [...]

Agnes Kraus was one of the most recognizable and popular television actors in the German Democratic Republic. She rose to prominence in the 1970s when she became known for almost exclusively playing Berlin mothers, grandmothers and widows, whose brusque but caring manner was exaggerated for comedic effect, and her characters frequently served as the bearers of traditions and community cohesion. The lasting appeal of Kraus and her characters among audiences from the former GDR is evident from the recent re-release of her television series and films, which are now marketed as 'Agnes Kraus films'. It may be tempting to attribute Kraus' ongoing appeal to a desire to revisit the community spirit of the GDR that is encapsulated in these series and films. However, such a conclusion requires closer investigation for, as this article will argue, much of Kraus' appeal in the 1970s and 1980s resided in the fact that her characters transcended the specificities of nationallyframed values and structures readily identifiable with the GDR.
