The aim of this study was to assess the incidence and trends of oesophageal adenocarcinomas (OACs) and squamous cell carcinomas (OSCCs) in England from 1971 to 2037.
Data on 220,026 oesophageal cancers diagnosed in England between 1971 and 2013 were extracted. Multiple imputation was used to predict morphology data were missing. Incidence rates were modelled and extrapolated to 2037 using age-period-cohort models.
The OAC age-standardised incidence rate (ASRs) increase was greatest from 1972 to 1992 (from 4.8 to 12.3 for men and 1.1 to 3 per 100,000 for women) and slowed from 1992 to 2012 (with an increase to 17 for men and 3.8 per 100,000 for women). OSCCs rates decreased from 7.5 to 4.9 from 1972 to 2012 for men. For women, ASRs increased from 5.5 to 5.9 between 1972 and 1992 and then decreased to 4.7 per 100,000 until 2012. Rates until 2032 are predicted to stay stable for OACs and further decrease for OSCCs.
Imputing missing morphology allowed accurate and up-to-date estimates of trends and projections. We observed a slowing down of the increase in OAC ASRs and an overall decrease in OSCC ASRs.
