METHODS: The data of patients diagnosed with UC between 2004 and 2016 were collected using the National Health Insurance Service database. The overall treatment trends were assessed according to the chemotherapy regimens. The MVAC and GC groups were matched by propensity scores. Cox proportional hazard analysis and Kaplan–Meier analysis were performed to assess survival. RESULTS: Of 3,108 patients with UC, 2,880 patients were treated with GC and 228 (7.3%) were treated with MVAC. The transfusion rate and volume were similar in both the groups, but the granulocyte colony-stimulating factor (G-CSF) usage rate and number were higher in the MVAC group than in the GC group. Both groups had similar OS. Multivariate analysis revealed that the chemotherapy regimen was not a significant factor for OS. Subgroup analysis revealed that a period of ≥3 months from diagnosis to systemic therapy enhanced the prognostic effects of the GC regimen. CONCLUSIONS: The GC regimen was widely used as the first-line chemotherapy in more than 90% of our study population with metastatic UC. The MVAC regimen showed similar OS to the GC regimen but needed greater use of G-CSF. The GC regimen could be a suitable treatment option for metastatic UC after ≥3 months from diagnosis.
