We can eradicate the global scourge of tobacco
378Asia, Africa and Latin America are at particular risk of marketing efforts by tobacco companies, with children being the most vulnerable. The Framework Convention on Tobacco Control has now become legally binding in the countries that have adopted it. John Seffrin discusses the global measures designed to prevent tobacco companies gaining a stronghold in developing countries, and reiterates why the US needs to be at the forefront in implementing these measures.

Serrated adenoma of the colorectum and the DNA-methylator phenotype
398Epithelial polyps of the colorectum have traditionally been classified into two main groups: neoplastic polyps or adenomas, and hyperplastic polyps. Serrated adenomas display features intermediate between hyperplastic polyps and adenomas. The absence of serrated adenomas in recently published series of colorectal polyps indicates that some pathologists do not recognize them. Yet, it is becoming increasingly clear that serrated adenoma serves as the precursor lesion for a major subset of colorectal cancers. It is likely that a significant proportion of these lesions do not evolve through the adenoma-to-carcinoma sequence, but through a largely independent 'serrated-polyp pathway' in which DNA methylation is a key genetic hallmark. Jass discusses the importance of the 'CpG-island-methylator phenotype' and the morphological and molecular correlations of serrated adenomas.

Therapy Insight: AIDS-related malignancies—the influence of antiviral therapy on pathogenesis and management
406Patients with HIV infection are at an increased risk of malignancies, especially Kaposi's sarcoma and certain B-cell lymphomas. Highly active antiretroviral therapy has helped to reduce the incidence of many HIV-associated tumors, but as the number of people living with AIDS is increasing, AIDS-associated malignancies will probably rise, posing a significant treatment challenge. Yarchoan et al. discuss the pathogenesis of AIDS-related malignancies, and describe the successful treatments for Kaposi's sarcoma and lymphomas using treatments based on viral, vascular or other pathogenesis-based targets.

Guidelines
REporting recommendations for tumor MARKer prognostic studies (REMARK)
416Despite the plethora of reports on tumor markers in oncology, the number of markers that have emerged as clinically useful is disappointing. There is considerable evidence that the quality of reporting of studies of biomarkers, particularly tumor prognostic markers, is generally poor. McShane et al. present guidelines that provide helpful suggestions on study design, patient characteristics, statistical analysis methods, and guidance on how to present data. The authors advocate the importance of transparent and complete reporting of tumor marker prognostic studies in order to increase accessibility and interpretability of trial data, which should help to improve patient treatment and management.
