The Office for National Statistics (ONS) is the UK’s largest independent producer of official statistics and is the recognized national statistical institute for the UK has collected and published cancer survival rate in England. Dataset includes one to five-year and predicted 10 year age standardized net survival estimates for adults (aged 15-99 years) diagnosed in England with one of the 21 most common cancers.
For the predicted estimates, they applied rules restricting the analyses to cancers and periods of follow-up for which sufficient data were available to make robust estimates of survival. This is because survival estimates are unstable when there are few patients at risk initially and when the number at risk drops sharply over time. Survival at a certain time since diagnosis is only reported if at least 10 patients were alive at that time; and if there were at least 5 events in either the years before or the years after; additionally, at least one event in the years before this time is required.
