Background Gastrointestinal stromal tumours ( GISTs ), despite complete surgical cytoreduction, are associated with recurrence rates of up to 50% at 2 years. At recurrence, tyrosine kinase inhibitor ( TKI ) therapy is recommended, conferring a survival of up to 55 months. Several studies have shown that patients with TKI ‐responsive recurrent GIST benefit from surgery. However, no studies have compared upfront surgery versus TKI alone. Methods Data were retrospectively collected from patients with recurrent GIST treated at S ingapore G eneral H ospital and N ational C ancer C entre S ingapore over a 12‐year period. Our primary end points were disease‐free and overall survival ( OS ). Results A total of 186 patients underwent curative surgery for GIST between J anuary 2000 and J une 2012. Fifty‐six (30%) patients experienced recurrence, of which 30 (54%) had resectable recurrent disease. Twenty‐four patients underwent upfront surgery for their recurrence while the remaining six patients opted for non‐surgical management. The median OS for all patients with recurrent GIST was 5.3 years (95% confidence interval ( CI ) 3.2–8.4). It was not reached for patients who underwent curative surgery for their recurrence, and was 3.9 years (95% CI 2.4–7.0) for patients who had palliative TKI and conservative management. There were significant differences in OS and disease‐specific survival between patients who underwent curative surgery for recurrence compared with those who had not. Conclusion Our study shows that upfront surgery is a reasonable treatment strategy for selected patients with recurrent GIST .
