Background
Oesophageal and gastric adenocarcinoma (OGA) treatment remains challenging. Improvements in early diagnosis, staging and management might have contributed to survival prolongation. To examine this hypothesis, we assessed outcomes of resected OGA patients in our institution over 10 years, comparing two time periods, 2001–2005 and 2006–2010.
Methods
Records from patients who had undergone surgery with radical intent and follow-up for OGA were retrospectively reviewed. Patients followed up at hospitals other than the Royal Marsden Hospital were excluded. Two different cohorts were identified: patients with oesophageal and type I or type II oesophagogastric junction (OGJ) tumours, and patients with gastric and type III OGJ tumours.
Results
We identified 360 patients: 147 from 2001–2005 and 213 from 2006–2010. The characteristics were comparable across the two time periods. Between 2001–2005 and 2006–2010, the percentage of R0 resections increased (from 67.1 to 81.1 % for proximal tumours and from 76.3 to 95.9 % for gastric and type III OGJ tumours). The mean number of lymph nodes retrieved increased over time. The 5-year overall survival rate increased significantly from 42.3 to 56.6 % for proximal tumours and from 38.8 to 55.3 % for gastric and type III OGJ tumours. Similarly, the disease-free survival rate significantly increased from 34.6 to 53.5 % for proximal tumours and from 35.9 to 51.1 % for gastric and type III OGJ tumours.
Conclusion
This study comprehensively describes the improvement in survival outcomes in a major UK referral centre over a 10-year period, identifying potentially relevant factors such as increased number of R0 resections and higher lymph node yield.
