Background
Radical surgery is attempted in a proportion of gastro oesophageal junction (GOJ) cancer patients and these selected patients have a good chance of long term survival. Increasing the resected proportion could possibly increase GOJ cancer survival in England. This presentation explores survival in relation to the intensity of radical surgical treatment for GOJ cancer.

Method
We identified 32,442 GOJ cancer patients from cancer registries in England, 1998-2003. Patients with radical surgical treatment were identified from the hospital episode statistics data. We computed the intensity of radical resection in GOJ cancer patients in PCT populations in England and assigned a PCT quintile of surgery to each patient. The survival of different groups of GOJ cancer patients were assessed in relation to PCT-quintile-of-surgery, age, sex, socio-economic deprivation, and cancer network, using Cox regression analysis.

Results
Intensity of radical resection ranged from 13% to 31% from the lowest to the highest PCT-quintile. Survival in the total patient population increased with radical surgery: upper vs. lower PCT-quintile: HR=0.90; p-trend<0.0001. Among the subset of resected patients, there was no statistically significant association (p-trend=0.79).

Conclusion
The data suggest that an increase in the intensity of radical surgery could plausibly lead to an overall increase in GOJ cancer survival. This analysis should be repeated for the next five year period as most cancer networks will have instituted action plans to comply with Improving Outcomes Guidance and radical surgery will have become more centralised.
