SummaryPopulation-level survival in older patients with lymphoma is significantly lower than in younger patients. In this study, data were obtained from cancer registries in England and the United States (US) for patients diagnosed with Hodgkin lymphoma (HL), non-Hodgkin lymphoma (NHL) and myeloma. Five-year relative survival was calculated using period analysis. Generalised linear models were used to determine excess hazard ratios (EHR) for older compared to younger patients. Five-year relative survival was lower for older patients diagnosed with HL, NHL and myeloma in both countries. The greatest age-related survival inequality was observed for patients with HL: in 2006-10 the EHR comparing patients aged 75 + years with those aged 15-24 years was 14Á02 in the US and 15Á69 in England. For NHL, the EHR was 1Á91 in the US and 3Á81 in England. For myeloma, comparing patients aged 75 + years with those aged 25-44 years, the EHR was 2Á79 in the US and 3Á60 in England. Survival of patients with lymphoma is lower for older patients in both the US and England but the discrepancy is less in the US. Physicians should be encouraged to evaluate patients' frailty and co-morbidities as well as their age when considering treatment options for patients with lymphoma and myeloma.Keywords: non-hodgkin lymphoma, hodgkin lymphoma, multiple myeloma, survival, disparity.Compared with younger patients, older age is a poor prognostic factor in patients with Hodgkin lymphoma (HL) Sj€ oberg et al, 2012), non-Hodgkin lymphoma (NHL) (Storm et al, 2010;Pulte et al, 2013), and myeloma (Brenner et al, 2008a;Renshaw et al, 2010). Possible reasons for this disparity include more aggressive disease, difficulty in treating older patients adequately due to co-morbidities and frailty, under-treatment due to fear of increased risk of complications in older patients, or a combination of these. An indirect method by which possible under-treatment can be investigated is comparison of survival of patients by age in different countries. A significant disparity in survival of older patients in different countries with similar overall life expectancy and level of medical care might suggest under-treatment in the population with lower survival.The United States (US) and England have quite different systems in respect of the delivery of health services. In England, although some individuals and employees have private health insurance, all citizens are covered by the National Health Service, which is free at the point of delivery. In the US there is no universal health coverage, with the exception of citizens and permanent residents aged 65 years and older who are eligible for Medicare, a government-run health insurance system.The aim of the current study was to compare survival by age, in patients with HL, NHL and myeloma in the US and England, as a preliminary investigation of the extent of which health system factors affect survival from haematological malignancies.
