BACKGROUND: Gastrointestinal stromal tumors (GISTs) commonly metastasize to the liver and peritoneum. Metastases may be detected synchronously at the time of initial diagnosis or develop metachronously after curative-intent resection. Nonetheless, the prognostic significance of metastasis timing in advanced GIST remains unclear.
METHODS: We retrospectively analyzed 147 patients with metastatic GIST treated at multiple institutions between 2003 and 2012. The patients were categorized into synchronous (n = 51) and metachronous (n = 96) groups. Clinicopathological characteristics and overall survival (OS) were compared using Kaplan-Meier analysis and Cox proportional hazards models. Among patients with metachronous disease, the outcomes were further evaluated according to the recurrence interval.
RESULTS: The median OS was significantly shorter in the synchronous group (6.7 years) than in the metachronous group (12.8 years; p = 0.001). Metastasis timing remained an independent prognostic factor in multivariable analysis (hazard ratio 2.36, 95% confidence interval 1.39-4.00; p = 0.001). Among patients with metachronous metastasis, early recurrence within 2 years after surgery was associated with significantly inferior survival compared to late recurrence.
CONCLUSION: Metastasis timing was associated with survival in patients with metastatic GIST. Both synchronous presentation and early metachronous recurrence were associated with poorer outcomes.
