Improved outcomes between time periods included reduced mortality for OG cancer and post\u2010surgical mortality 1\u2009year post gastrectomy. Patient multidisciplinary meeting presentation increased from 74% to 86%. Unwarranted variations included time from diagnosis to any treatment within 6\u2009weeks for non\u2010metastatic gastric cancer (64%, 2012\u20132016 and 60%, 2017\u20132021) and for oesophageal cancer patients (58%, 2012\u20132016 and 60%, 2017\u20132021). One regional Integrated Cancer Service (ICS) demonstrated statistically lower survival compared to the statewide average for gastric cancer in 2017\u20132021. There was greater variation in survival for gastric cancer for 2017\u20132021 compared to 2012\u20132016.
