This paper provides a synthesis on socioeconomic inequalities in cancer incidence, mortality and survival across countries and within countries, with particular focus on the Italian context; the paper also describes the underlying mechanisms documented for cancer incidence, and reports some remarks on policies to tackle inequalities. From a worldwide perspective, the burden of cancer appears to be particularly increasing in developing countries, where many cancers with a poor prognosis (liver, stomach and oesophagus) are much more common than in richer countries. As in the case of incidence and mortality, also in cancer survival we observe a great variability across countries. Different studies have suggested a possible impact of health care on the social gradients in cancer survival, even in countries with a National Health System providing equitable access to care. In developed countries, there is increasing awareness of social inequalities as an important public health issue; as a consequence, there is a variety of strategies and policies being implemented throughout Europe. However, recent reviews emphasize that present knowledge on effectiveness of policies and interventions on health inequalities is not sufficient to offer a robust and evidence-based guide to the choice and design of interventions, and that more evaluation studies are needed. The large disparities in health that we can measure within and between countries represent a challenge to the world; social health inequalities are avoidable, and their reduction therefore represents an achievable goal and an ethical imperative.

Background The aim of this study was to describe the patterns of marriage and parenthood in a cohort of childhood cancer survivors included in the Off-Therapy Registry maintained by the Italian Association of Pediatric Hematology and Oncology. Design and Methods We analyzed a cohort of 6,044 patients diagnosed with cancer between 1960 and 1998, while aged 0 to 14 years and who were 18 years old or older by December 2003. They were followed up through the regional vital statistics registers until death or the end of follow up (October 30, 2006), whichever occurred first, and their marital status and date of birth of their children were recorded. The cumulative probabilities of being married and having a first child were computed by gender and compared by tumor type within the cohort. Marriage and fertility rates (the latter defined as the number of live births per woman-year) were compared with those of the Italian population of the same age, gender, area of residence and calendar period by means of the observed to expected (O/E) ratios. Results During the follow-up period, 4,633 (77%) subjects had not married. The marriage O/E ratios were 0.56 (95% CI: 0.51–0.61) and 0.70 (95% CI: 0.65–0.76) among men and women, respectively. Overall, 263 men had 367 liveborn children, and 473 women had 697 liveborn children. The female fertility O/E ratio was 0.57 (95% CI: 0.53–0.62) overall, and 1.08 (95% CI: 0.99–1.17) when analyses were restricted to married/cohabiting women Conclusions Childhood cancer survivors are less likely to marry and to have children than the general population, confirming the life-long impact of their previous disease on their social behavior and choices. The inclusion of counseling in the strategies of management and long-term surveillance of childhood cancer patients could be beneficial to survivors as they approach adulthood.

BACKGROUND.: It has been established that promoter hypermethylation occurs in several genes during the pathogenesis of head and neck cancer. The authors investigated the role played by the hypermethylation of 4 cancer‐related genes in the survival of patients who had laryngeal and hypopharyngeal cancer and in the occurrence of second primary tumors.METHODS.: Archival paraffin‐embedded tissue (PET) samples were available from patients who were enrolled in a multicentric European case‐control study that was performed between 1979 and 1982 and was followed up to 2000. Genomic DNA extracted from 235 PET samples were analyzed for promoter methylation status of the p16, O⁶‐methylguanine‐DNA methyltransferase (MGMT), death‐associated protein kinase (DAP‐K), and E‐cadherin genes by using a methylation‐specific polymerase chain reaction assay.RESULTS.: Hypermethylation was present in 44% of samples for p16, in 27% of samples for MGMT, in 42% of samples for DAP‐K, and in 43% of samples for E‐cadherin. Hypermethylation of either individual genes or their combination was not associated with mortality from all causes, mortality from upper aerodigestive tract cancer, or the occurrence of second primary tumors.CONCLUSIONS.: The analysis of a large series of patients with laryngeal and hypopharyngeal cancer suggested that hypermethylation is a frequent event in laryngeal and hypopharyngeal cancer, but it is not a predictor of mortality or second primary cancer.
